Free Practice Questions for the HP Aruba Certified Professional - Campus Access HPE7-A01 Exam (2026 Updated)

The reason is that the linkup delay timer is a feature that delays bringing downstream VSX links up, following a VSX device reboot or an ISL flap. The linkup delay timer has two phases: initial synchronization phase and link-up delay phase.

The initial synchronization phase is the download phase where the rebooted node learns all the LACP+MAC+ARP+STP database entries from its VSX peer through ISLP. The initial synchronization timer, which is not configurable, is the required time to download the database information from the peer.

The link-up delay phase is the duration for installing the downloaded entries to the ASIC, establishing router adjacencies with core nodes and learning upstream routes. The link-up delay timer default value is 180 seconds. Depending on the network size, ARP/routing tables size, you might be required to set the timer to a higher value (maximum 600 seconds).

When both VSX devices reboot, the link-up delay timer is not used.

Therefore, by configuring the linkup delay timer to include LAGs 101 and 102, which are part of the same VSX device as LAG 201, you can ensure that both devices have enough time to synchronize their databases and form routing adjacencies before bringing down their downstream links.

Active Gateway is the first-hop protocol feature that is used for VSX L3 gateway as per Aruba recommendation. Active Gateway is a feature that allows both VSX peers to act as active gateways for different subnets, eliminating the need for VRRP or other first-hop redundancy protocols. Active Gateway also provides fast failover and load balancing for L3 traffic across the VSX peers. The other options are incorrect because they are either not recommended or not supported by Aruba CX VSX.

The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna. A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario. References: https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/wlan-rf/rf-fundamentals.htm https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/wlan-rf/antennas.htm

The calculated Equivalent Isotropic Radiated Power (EIRP) for AP1 is 17 dBm.

EIRP is the measured radiated power of an antenna in a specific direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It can also take into account the losses in transmission line, connectors, and other components. The formula for EIRP is:

EIRP = P + G - L

where P is the output power of the radio, G is the gain of the antenna, and L is the loss of the cable and connectors.

For AP1, we have:

P = 10 dBm G = 9 dBi L = 2 dB

Therefore,

EIRP = 10 + 9 - 2 EIRP = 17 dBm

These are two correct statements regarding OSPFv2 route redistribution for Aruba OS CX switches. Route redistribution is a process that allows routes from one routing protocol or source to be injected into another routing protocol or destination. OSPFv2 is a link-state routing protocol that supports route redistribution from various sources, such as connected, static, BGP, etc. The “redistribute connected” command will redistribute all connected routes for the switch, including local loopback addresses, into OSPFv2. The “redistribute static route-map connected-routes” command will redistribute all static routes that have a matching permit statement in the route map named “connected-routes” into OSPFv2. The other statements are incorrect because they either do not reflect the correct behavior of route redistribution commands or do not exist as valid commands.

Wi-Fi 6 is an industry certification for products that support the new wireless standard 802.11ax, also known as “high-efficiency wireless”. Wi-Fi 6 offers increased capacities, improved resource utilization and higher throughput speeds than previous standards.

Option B: ClientMatch

This is because option B shows how to use ClientMatch to optimize the wireless performance of Wi-Fi 6 clients on a UniFi network.  ClientMatch is a feature that uses machine learning to analyze the traffic patterns of each client and assign them to the best available AP based on their location, device type, and network conditions 2 .

Therefore, option B is the best technology to implement for your customer’s issue.

The correct answer is C. Create a new SVI and use attach command.

To create a new SVI for a separate routing table, you need to use the attach command to associate the SVI with a VRF (Virtual Routing and Forwarding) instance. A VRF is a logical entity that allows multiple routing tables to coexist on the same switch. Each VRF has its own set of interfaces, routing protocols, and routes that are isolated from other VRFs.

According to the AOS-CX Virtual Switching Framework (VSF) Guide 1 , one of the steps to configure VRF-aware VSF is:

Configure the VRFs on each member switch and assign the SVIs to the respective VRFs using the attach command. For example:

switch(config)# vrf red

switch(config-vrf)# exit

switch(config)# interface vlan 10

switch(config-if-vlan)# ip address 10.1.1.1/24

switch(config-if-vlan)# attach vrf red

The above commands create a VRF named red and assign VLAN 10 SVI to it. The SVI has an IP address of 10.1.1.1/24.

The other options are incorrect because:

A. You cannot attach a VRF to a VLAN directly. You need to create an SVI for the VLAN and then attach the VRF to the SVI.

B. You cannot create a new routing table manually. You need to create a VRF and then use routing protocols or static routes to populate the routing table for the VRF.

D. You cannot attach a routing table to a VLAN directly. You need to create an SVI for the VLAN and then attach a VRF that has a routing table associated with it.

The correct answer is B. An event log message is created.

The do-not-disable parameter is used to prevent the switch from disabling the port when a loop is detected by the loop-protect feature. Instead, the switch will generate an event log message that indicates the port number and the VLAN ID where the loop was detected. The switch will also send a trap to the SNMP manager, if configured 1 .

The other options are incorrect because:

A. Port status will not be validated once status is cleared. The port will remain enabled even if a loop is detected, unless the loop-protect action is changed to tx-disable or tx-rx-disable 1 .

C. The network analytics engine will not be triggered by a loop detection. The network analytics engine is a feature that allows users to monitor and troubleshoot network issues using scripts and agents 2 .

D. Port status LED will not blink in amber with 100Hz. The port status LED will indicate the normal port status, such as link speed and activity, regardless of the loop detection 3 .

The persona role option that should be selected to deploy a Gateway and take advantage of all the SD-WAN features is A. ArubaOS 10 Branch.

ArubaOS 10 Branch is a persona that enables the Gateway to provide both LAN and WAN functionality for branch networks. The Gateway can act as a wireless controller, a router, a firewall, and an SD-WAN device. The SD-WAN features include route and tunnel orchestration, dynamic path steering, forward error correction, SaaS traffic optimization, SASE orchestration, and more 1 .

The other options are incorrect because:

B. ArubaOS 10 VPN Concentrator: This is a persona that enables the Gateway to act as a VPN concentrator for remote access or site-to-site VPN connections. It does not provide SD-WAN features 2 .

C. ArubaOS 10 Wireless: This is a persona that enables the Gateway to act as a wireless controller for campus networks. It does not provide SD-WAN features 3 .

D. ArubaOS 10 Mobility: This is a persona that enables the Gateway to act as a mobility controller for campus networks. It does not provide SD-WAN features.

This is the correct explanation of how roles can help keep consistent policy enforcement in a distributed overlay fabric. Roles are used to assign group based policy IDs (GBPs) to devices after they authenticate with ClearPass or a local database. GBPs are then used to tag the traffic from the devices and send them to the ingress VTEP, which applies the GBP on the VXLAN header. The egress VTEP then enforces the policy based on the GBP and the destination device. The other options are incorrect because they either do not describe the correct sequence of events or do not use the correct terms. References: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch03.html https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch05.html

Active gateway is a first hop redundancy protocol that eliminates a single point of failure. The active gateway feature is used to increase the availability of the default gateway servicing hosts on the same subnet. An active gateway improves the reliability and performance of the host network by enabling a virtual router to act as the default gateway for that network.  If you have enabled active gateway, VRRP is not required 3 . Active gateway is similar to VRRP in that routed traffic from the VSX node is sourced from the switch interface MAC and not the virtual MAC address (VMAC). Each active gateway sends a periodic broadcast hello packet to avoid VMAC aging on the access switches.  The switch views the active gateway IP as a self IP address 3 .  Active gateway is preferable over VRRP because with VRRP traffic is still pushed over the ISL link, resulting in latency in the network 3 . Therefore, VRRP and active gateway are mutually exclusive on a VLAN, and answer A is correct.

According to the Aruba Documentation Portal 1 , PAPI (Port Aggregation Protocol) is a protocol that allows multiple physical ports to be aggregated into a single logical port for increased bandwidth and performance. PAPI can be used between AOS-CX switches and gateways, or between AOS-CX switches and other devices.

Option A: Implement an IPSec tunnel to protect PAPI between the AOS-CX switches and the gateway

This is because option A shows how to implement an IPSec tunnel between two devices using the interface command and the ipsec command.  An IPSec tunnel can provide encryption and authentication for PAPI traffic between two devices, such as an AOS-CX switch and a gateway 2 .

Therefore, option A is a feasible option to protect this traffic.

I hope this helps you. If you need more information, please let me know. ????

Multi-Domain Authentication is the feature that should be enabled to support the requirement that the switch must be able to authenticate a single computer connected through a VoIP phone. Multi-Domain Authentication is a feature that allows an Aruba CX switch to apply different authentication methods and policies to different devices connected to the same port. For example, a VoIP phone and a computer can be connected to the same port using a single cable, but they can be authenticated separately using different credentials and assigned to different VLANs. The other options are incorrect because they either do not support multiple devices on the same port or do not provide authentication. References: https://www.arubanetworks.com/techdocs/AOS-CX/10.05/HTML/5200-7540/GUID-7D9E9F6E-5C2A-4F7E-BE6D-A2C3A6C7B9F9.html https://www.arubanetworks.com/assets/tg/TB_ArubaCX_Switching.pdf

The important advantage supplied by SNMPv3 is enhanced security, including authentication and message integrity . SNMPv3 employs a User-based Security Model in which authentication protocols such as MD5 or the SHA family can validate the sender and verify that the SNMP message has not been altered during transmission. HPE Aruba specifically documents SNMPv3 authentication protocols and recommends SNMPv3 because it provides authentication and strong privacy mechanisms that are absent from SNMPv2c. Aruba Networking

SNMPv2c relies on community strings , which are transmitted without the stronger user-based authentication and privacy protections available in SNMPv3. Aruba notes that SNMPv1 and SNMPv2c community names can be transmitted in clear text, whereas SNMPv3 supports authenticated users and encrypted management traffic. Aruba Networking

Options A and B are not unique SNMPv3 advantages. 64-bit counters were introduced with SNMPv2, particularly through Counter64 objects, and GetBulk was also introduced with SNMPv2 to improve retrieval efficiency. Option C is actually characteristic of SNMPv1/v2c rather than an SNMPv3 improvement.

Consequently, the distinguishing SNMPv3 feature among the available answers is message integrity .

Study Guide Topics: SNMPv3, SNMPv2c, User-Based Security Model, Authentication, Message Integrity, Privacy/Encryption, AOS-CX Network Management.

The statements that are true regarding Aruba NAE agents are A and C.

A. A single NAE script can be used by multiple NAE agents. This means that you can create different instances of the same script with different parameters or settings. For example, you can use the same script to monitor different VLANs or interfaces on the switch 1 .

C. NAE agents will never consume more than 10% of switch processor resources. This is a built-in safeguard that prevents the agents from affecting the switch performance or stability. If an agent exceeds the 10% limit, it will be automatically disabled and an alert will be generated 2 .

The other options are incorrect because:

B. NAE agents are not active at all times. They can be enabled or disabled by the user, either manually or based on a schedule. They can also be disabled automatically if they encounter an error or exceed the resource limit 1 .

D. NAE scripts do not need to be reviewed and signed by Aruba before being used. You can create your own custom scripts using Python and upload them to the switch or Aruba Central. You can also use the scripts provided by Aruba or other sources, as long as they are compatible with the switch firmware version 1 .

E. A single NAE agent cannot be used by multiple NAE scripts. An agent is an instance of a script that runs on the switch. Each agent can only run one script at a time 1 .

For switches to participate in the same Multiple Spanning Tree Protocol (MSTP) region , their MST region configuration must match. One of the critical parameters is the configuration revision number , configured in AOS-CX using:

spanning-tree config-revision < REVISION-NUMBER >

HPE Aruba Networking explicitly states that all switches within an MST region must have identical revision numbers . The revision number forms part of the MST region identity along with the configuration name and VLAN-to-instance mapping. Aruba Networking

This is essential for VLAN load balancing because MSTP allows different VLAN groups to be mapped to different MST instances. Each instance can then use a different spanning-tree topology/root, allowing otherwise blocked redundant links to forward traffic for other VLAN groups. Aruba ' s MSTP configuration example specifically demonstrates that changing the root for individual instances permits more effective load sharing across redundant links. Aruba Networking

The spanning-tree priority does not need to be identical; in fact, different instance priorities are deliberately used when different switches should become roots for different MST instances. Likewise, “root” and “secondary root” describe root-election behavior rather than an MST region parameter that must be identical across Access-1 and the other participating switches.

Therefore, among the choices, spanning-tree config-rev is the required identical configuration.

Study Guide Topics: MSTP, MST Regions, Configuration Revision, VLAN-to-MSTI Mapping, Root Bridge Selection, VLAN Load Balancing.

The correct built-in AOS-CX management role is administrators . HPE Aruba Networking defines the administrators group as the default role with full management privileges and explicitly assigns it privilege level 15 . Members of this group can perform firmware upgrades, modify switch configuration, view sensitive configuration information, add or remove local user accounts, change passwords, and use all supported REST API methods. Aruba Networking

The existing auditors assignment does not satisfy the requirement. The auditors group is intentionally restricted to audit-related operations and is assigned privilege level 19 , not 15. Its CLI access is limited to the auditor context, and its Web UI and REST API permissions are similarly restricted to logging and auditing resources. Aruba Networking

AOS-CX also documents the mapping used with TACACS+: privilege level 15 maps to administrators , privilege level 1 maps to operators, and privilege level 19 maps to auditors. Aruba Networking

Therefore, because this user needs both firmware-upgrade capability and privilege level 15 , the appropriate default management role is administrators .

Study Guide Topics: AOS-CX Management Users, Built-in User Groups, RBAC, Privilege Levels, Administrators vs. Auditors, Firmware Management, TACACS+ Authorization.

According to the Aruba Documentation Portal 1 , the ArubaOS-CX switch supports various features to control the ingress traffic on specific ports, such as rate limiting, QoS shaping, and access control. These features can help reduce the impact of excessive broadcast traffic on the network performance and availability.

This is because rate limiting is a feature that allows you to limit the inbound or outbound traffic on a port based on a percentage of the port capacity or a fixed amount of bytes per second.  Rate limiting can help prevent broadcast storms by reducing the amount of broadcast packets that enter or leave a port

 https://www.arubanetworks.com/techdocs/central/latest/content/nms/aos-cx/cfg/conf-cx-access-control.htm  2 : https://community.arubanetworks.com/blogs/esupport1/2021/02/08/broadcast-storm-containment-in-aruba-pvos-switches  3 : https://techhub.hpe.com/eginfolib/networking/docs/switches/K-KA-KB/15-18/5998-8160_ssw_mcg/content/ch05.html

On an AOS-CX switch , REST API authentication uses the HTTP POST method against the login resource. Aruba specifies that a REST API session is initiated by sending the username and password through a POST request. After successful authentication, the switch returns session information that is used for subsequent API requests. Aruba Networking

For changing the administrator password, Aruba documents the use of PUT against the user resource, for example PUT /rest/v10.xx/system/users/admin, with the new password included in the request data. Therefore, D correctly associates POST with login and PUT with changing the management password . Aruba Networking

Option A is incorrect because AOS-CX does not provide comprehensive semantic validation for REST writes. Aruba explicitly warns that configuration errors written directly to the database can destabilize the switch. Aruba Networking

Option B is also incorrect. Read-only mode blocks writes to most resources, but exceptions exist. POST is still permitted for functions such as login , and certain PUT/POST operations remain available. Aruba Networking Option C simply reverses the correct HTTP methods.

Study Guide Topics: AOS-CX REST API, REST Authentication, HTTP POST/PUT Methods, API Access Modes, Read-Write versus Read-Only Access.

The difference in the noise floor perceived by a client using a bonded 40 MHz wide channel as compared to an unbonded 20 MHz wide channel is 3 dB. The noise floor is the level of background noise in a given frequency band. When two adjacent channels are bonded, the noise floor increases by 3 dB because the bandwidth is doubled and more noise is captured. The other options are incorrect because they do not reflect the correct relationship between bandwidth and noise floor.

The reason is that ClearPass OnBoard is a tool that allows you to enroll Mac computers into a ClearPass Policy Manager site using an Apple MDM push certificate. This certificate can be obtained from Apple or from a third-party PKI provider.

Aruba 9004 gateway supports ZTP on port G0/0/0 by default 1 .  If the gateway is connected to a different port, such as G0/0/V1, it will not be able to communicate with Aruba Activate and Aruba Central, which are required for ZTP 2 .  Moreover, port G0/0/V1 is configured as a DHCP server by default, which can cause IP address conflicts with the existing network 3 . Therefore, the technician should move the cable on the gateway to port G0/0/0, which will allow the gateway to obtain an IP address from the network DHCP server and start the ZTP process. The other options are not correct because they will not solve the issue or enable ZTP.  For example, option D will not work because factory defaulting and rebooting the gateway will not change the port configuration or behavior 3 .

The correct answers are A and D.

According to the web search results, VSX LAG is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless IoT devices 1 . VSX LAGs span both aggregation switches and appear as one device to partner downstream or upstream devices or both when forming a LAG with the VSX pair 2 .

One of the statements that is true about VSX LAG is that the total number of configured links may not exceed 8 for the pair or 4 per switch 1 . This means that a VSX LAG across a downstream switch can have at most a total of eight member links, and a switch can have a maximum of four member links. When creating a VSX LAG, it is recommended to select an equal number of member links in each segment for load balancing 1 .

Another statement that is true about VSX LAG is that outgoing traffic is preferentially switched to local members of the LAG 2 . This means that when active forwarding and active gateway are enabled, north-south and south-north traffic bypasses the ISL link and uses the local ports on the switch. This optimizes the traffic path and reduces the load on the ISL link 2 .

The other statements are false or not relevant for VSX LAG. Outgoing traffic is not switched to a port based on a hashing algorithm, which may be either switch in the pair. This is a characteristic of MLAG (Multi-Chassis Link Aggregation), which is a different feature from VSX LAG. LAG traffic is not passed over VSX ISL links only while upgrading firmware on the switch pair. This is a scenario that may occur when performing hitless upgrades, which is a feature that allows software updates without impacting network availability. The number of VSX lags that can be configured on all 83xx and 84xx model switches is not 255, but depends on the switch model and firmware version. For example, the AOS-CX 10.04 supports up to 64 VSX lags for 8320 switches and up to 128 VSX lags for 8325 and 8400 switches.

Option C is the correct configuration to ensure that APs will work properly. It uses the  ap  command to configure a port profile for APs with VLAN 100 as the native VLAN and VLAN 200 and 300 as tagged VLANs. It also enables LLDP on the ports to discover the APs and assign them to the port profile automatically. The other options are incorrect because they either do not use the  ap  command, do not enable LLDP, or do not configure the VLANs correctly. References: https://www.arubanetworks.com/techdocs/AOS-CX_10_08/UG/bk01-ch02.html https://www.arubanetworks.com/techdocs/AOS-CX_10_08/UG/bk01-ch03.html

The required optimization is to use IEEE 802.3az Energy Efficient Ethernet (EEE) across the AP deployment. Aruba documentation states that 802.3az allows supported APs to consume less power during periods of low data activity , which directly matches the scenario of reducing nighttime energy consumption. Aruba Networking

However, Aruba explicitly documents that 802.3az is not supported on the AP-315 or the 330 Series , which includes the AP-335. Aruba Networking Consequently, those older AP-315 and AP-335 units must be replaced with models supporting EEE. The AP-515 belongs to a newer generation and does not fall within Aruba ' s documented EEE exclusions, so replacing the AP-515 is unnecessary.

After installing EEE-capable replacements, 802.3az should be enabled across the AP environment , allowing Ethernet links to reduce power usage during low-traffic periods.

IPM is not the primary mechanism for this requirement. Aruba describes Intelligent Power Monitoring as dynamically restricting AP functions when AP consumption approaches or exceeds its available power budget . It is primarily concerned with operating an AP within available PoE resources, rather than automatically exploiting nighttime Ethernet inactivity. Aruba Networking

Study Guide Topics: Energy Efficient Ethernet (802.3az), AP Ethernet Link Profiles, AP Power Optimization, Intelligent Power Monitoring (IPM), Campus WLAN Sustainability.

MAC Caching is a feature that allows a guest user to bypass the captive portal page after the first authentication based on their MAC address 1  MAC Caching can be enabled under the splash page settings in Aruba Cloud Guest 2  MAC Caching can improve the user experience and reduce the network overhead by eliminating the need for repeated authentication.

This is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports. A dedicated management port is a physical port that is used exclusively for out-of-band management access to the switch. A dedicated management VRF is a virtual routing and forwarding instance that isolates the management traffic from other traffic on the switch. By creating a dedicated management VRF and assigning the management port to it, the administrator can enhance the security and performance of the management access to the switch. The other options are incorrect because they either do not apply to switches with dedicated management ports or do not follow Aruba-recommended best practices.

A failed VLAN Probe indicates that the gateway cluster members do not have the required common Layer 2 connectivity for those VLANs. When the VLAN probes fail, the relationship between cluster members is effectively treated as L3-connected rather than L2-connected . Aruba’s clustering documentation distinguishes these two operating conditions very clearly.

For an L3-connected cluster , only APs are fully replicated . Client/user information is not fully synchronized between cluster members, and high-value application sessions are not synchronized. Aruba’s official ArubaOS 8 Fundamentals Guide summarizes the distinction as follows: for L2-connected members, APs and clients are fully replicated, users and high-value sessions are synchronized, and failover occurs without deauthentication. For L3-connected members, only APs are fully replicated , users and high-value sessions are not synchronized, and users can be deauthenticated during failover. Aruba Networks

Therefore, option B precisely describes the outcome when VLAN probing fails across the required VLANs. Option A requires L2-connected clustering. Option C describes full L2 redundancy. Option D is reversed: L3-connected operation does not provide hitless client failover and users may be deauthenticated during a gateway failure. Aruba Networking

Study Guide Topics: Gateway Clustering, VLAN Probe, L2-Connected vs. L3-Connected Clusters, AP/Client State Synchronization, Stateful Failover, High-Value Session Synchronization.

These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work.

The command loop-protect enables loop protection on each layer 2 interface (port, LAG, or VLAN) for which loop protection is needed. Loop protection can find loops in untagged layer 2 links, as well as on tagged VLANs.

Policy Manager uses Group Policy Identifier (GPID) to carry policy information in traffic for in-line enforcement. Policy Manager also integrates with Cloud Auth, ClearPass, or third-party solutions to provide flexible network access control.

The other options either use more commands or do not create the VRF or the VLAN.

Option C uses the following commands:

vrf eng: This command creates a VRF named eng and enters the VRF configuration mode 1 .

vlan 25: This command creates a VLAN with ID 25 and enters the VLAN configuration mode 2 .

interface vlan 25: This command creates an SVI on VLAN 25 and enters the interface configuration mode 3 .

ip address 10.105.43.1/24 ipv6 address fd00:5780::102d:4df6/64 vrf attach eng: This command assigns an IPv4 address of 10.105.43.1 with a subnet mask of 255.255.255.0 and an IPv6 address of fd00:5780::102d:4df6 with a prefix length of 64 to the SVI, and attaches it to the VRF eng.

QoS stands for Quality of Service and is a mechanism that allows network devices to prioritize and differentiate traffic based on certain criteria, such as application type, source, destination, etc 3 .  QoS involves identifying specific traffic for special treatment and applying policies and actions to improve its performance or meet certain service level agreements (SLAs) 3 .  QoS can help network devices to manage congestion, delay, jitter, packet loss, bandwidth allocation, etc., for different types of traffic 3 .  QoS can be implemented at various layers of the network stack and across different network domains.
