HPE6-A47 Designing Aruba Solutions Questions and Answers

Questions 4

A customer needs a wired network solution that can recognize and prioritize a wide array of different types of traffic, including casual Web browsing, voice, video, SAP Online, and file sharing.

The architect needs to choose between the Aruba 2930F or the 2540 Switch Series for the access layer switch. Why would the architect choose the 2930F rather than the 2540 Switch Series for this customer?

Options:

A.

The 2930F Series supports LLDP-MED for detecting VoIP traffic, while the 2540 Series does not.

B.

The 2930F Series supports advancing routing, including multi-area OSPF, while the 2540 Series does not.

C.

The 2930F Series supports more options for class-based QoS policies that the 2540 Series.

D.

The 2930F Series can provide better congestion management with its much deeper buffers.

A.

MCs should be deployed centrally on the same VLAN to better meet these goals

B.

MCs in a cluster must have additional AP licenses to support APs of a failed controller

C.

The MC 7030 does not support enough APs for the requirements

D.

The MC 7030 only supports clusters with up to three members

Questions 15

Read this scenario thoroughly, and then answer each question that displays on the right side of the screen.

An architect proposes these products for a customer who wants a wireless and wired upgrade:

  • Aruba 2930M switches at the access layer
  • Aruba 5406R switches at the core
  • Aruba AP-325s
  • Aruba 7205 Mobility Controllers (MCs), deployed in a cluster
  • Aruba Mobility Master (MM)
  • Aruba ClearPass Cx000V
  • Aruba AirWare

The architect also needs to propose a security plan for the solution. The customer has 900 employees and up to 30 guests a day. The customer wants to protect the internal perimeter of the network with authentication and simple access controls. The customer is most concerned about wireless security, but also wants to ensure that only trusted users connect on the wire. However, the customer also wants all wired traffic to be forwarded locally on access layer switches. The customer already has a third-party firewall that protects the data center.

The customer wants to use certificates to authenticate user devices, but is concerned about the complexity of deploying the solution. The architect should recommend a way to simplify. For the most part users connect company-issued laptops to the network. However, users can bring their own devices and connect them to the network. The customer does not know how many devices each user will connect, but expects about two or three per-user. DHCP logs indicate that the network supports a maximum of 2800 devices.

Refer to the provided scenario.

Which solution should the architect recommend on the 2930M switches to authenticate and control wired employee devices?

Options:

A.

MAC-Auth on edge ports and no tunneled node

B.

802.1X on edge ports and per-user tunneled node

C.

802.1X on edge ports and no tunneled node

D.

Mac-Auth on edge ports and per-user tunneled node

C.

assign wired users to different VLANs from wireless users, based on port or role assignments on access layer switches. Extend the VLANs to the core.

D.
