An administrator has a VM that consumes large amounts of storage and has the following characteristics:
• Create large / sequential writes
• Data must be kept for years
• Data is normally only accessed at the end of the year to run report
The administrator decides to use Erasure Coding to save space.
Which feature should the administrator utilize to save space for this VM?
An administrator needs to make sure an RF2 cluster can survive a complete rack failure without negatively effecting workload performance. The current cluster configuration consists of the following:
• 30 nodes: distributed 10 nodes per rack across three 42U rack
• Each nodes is configured with 40TB usable storage all flash (Cluster Total 1.2 PB Usable)
• Current cluster utilization is 900TB storage
Which configuration changes should be made to make sure that the cluster meets the requirements?
What is the minimum number of blocks required to utilize block awareness?
A 2
B. 3
C. 4
Refer to the exhibit.
After performing ESXi to AHV conversion on a cluster, the alerts shown in the exhibit display on Prism. What should the administrator do to resolve this issue efficiently?
An organizations Nutanix Cluster is based on VMware vSphere. The cluster is configured to download software updates automatically. The administration needs to verify and eventually upgrade VMware hypervisor via Prism Ul.
After logging in to Prism, the administrator receives the message shown:
No available versions for upgrade
What is causing the current state?
An application owner had reported that an AHV - based critical application VM is performing very slowly, after initial diagnostics is has been observed that the CPU utilization is significantly higher than normal.
What two actions should the administrator take on this VM without shutting it down? choose two.
An administrator is unable to discover a Nutanix-hosted iSCSI Block device allocated to a bare-metal host.
What is causing this issue?
In a Nutanix cluster, a Protection Domain contains 50 entities that are replicated to a remote Single Node Replication Target.
The current schedule configuration is as follows:
• Repeat every 6 hours
• Local Retention Policy 1
• Remote Retention Policy 8
• Starting time 12 am
At 8 am on Monday, the administrator discovers that a protected VM is corrupted. The latest good state was Sunday 2 pm. The administrator needs to maintain current protection.
Which strategy should the administrator use to meet these requirements?
An administrator is updating disk firmware using LCM and receives the following message:
“there have been 10 or more cluster services restarts within 15 minutes in the Controller VM”
The message appears as each drive is upgraded.
What is the reason this message is being generated?
An administrator is currently using both 10g uplink with LACP and balance-tcp. A single VM should not be allowed to use more than a single 10G uplink, and both uplinks should be utilized.
Which two command should be used to configure the bond? (choose two)
A systems administrator configures a protection domain replication between two Nutanix clusters. After the first successful replication, the administrator tests DR by clicking activate on the remote cluster.
While VMs are active on the remote cluster, the protection domain is marked as active on both clusters.
What steps are required to return both clusters to their original state?
An administrator receives reports that VDI desktop performance in an 8-node Nutanix VDI environment is poor. Opening applications takes between 1 and 2 minutes.
When investigating the issue, the following conditions are found:
• Cluster memory utilization: 80%
• Cluster SSD utilization: 70%
• Average VM CPU Wait Time: 11%
• CVM CPU utilization: 75%
Which action should be taken to improve VDI performance?
A three-node cluster has a Nutanix Files instance with three FSVMs.
What happens after a node failure?
An administrator needs to replace the self-signed certificate on a cluster. Which two requirements must be met as part of the process? (Choose two.)
An administrator has a custom backup application that requires a 2TB disk and runs in Windows. Throughput is considerably lower than expected.
The application was installed on a VM with the following configuration:
• Four vCPUs with one core/vCPU
• 4GB of Memory
• One 50GB vDisk for the Windows installation
• One 2TB vDisk for the application
What is the recommended configuration change to improve throughput?
The networking team makes changes to the Top of Rack switches to which the Nutanix cluster are attached. A few VMs are able to communicate with each other on the same node but are unable to connect to other parts of the network.
What is the likely cause of this issue?
An administrator needs to provide data integrity at the application level for a VM that is replicated to a secondary site.
Which requirement will satisfy this task?
An organization subscribes to field advisories from the Nutanix support portal. An administrator receives an email about a rare problem that could cause cluster instability and affect the entire AOS cluster. The organization is running Vmware vsphere 6.x on Nutanix.
What action should be taken to resolve this issue?
A Nutanix cluster is deployed with the following configuration:
• Three four-node blocks (A, B, and C)
• All Flash Redundancy Factor 2
What is the effect of simultaneous disk failures on two nodes located in block A?
An administrator is responsible for the following Nutanix Enterprise Cloud environment:
• A central datacenter with a 20-node cluster with 1.5PB of storage
• Five remote sites each with a 4-node cluster with 200TB storage
The remote sites are connected to the datacenter via 1GB links with an average latency of 6 ms RTT. What is the minimum RPO the administrator can achieve for this environment?
An administrator is performing a set of routine checks and notes that Prism Central is running with 4 vCPUs and 21 GB RAM. The organizations environment is based on two Nutanix clusters with 170 VMs plus a Legacy vSphere infrastructure. No manual changes have been done on Prism Central VM.
Which configuration justifies the current Prism Central configuration?
