• Question 1:

  Refer to the exhibit.

  

  An administrator creates a security policy that isolates their financial application from accessing the Internet When viewing the policy in Prism Central, several connections from the application are outbound to the Internet. What is causing this issue with the policy?

  A. The 0.0.0.0 address was not specified in the outbound rule.

  B. The blocked connections are illustrated for information only.

  C. The Activate box was not checked in the rule, so it is not enforcing.

  D. The policy has been left in monitor mode instead of enforcing mode.

• Question 2:

  Over the period of 2 to 3 weeks, a cluster displays the following:

  Periods where Warning Alerts of memory usage over 75% are asserted Periods where Critical Warnings of memory usage over 90% are asserted Periods of slow of frozen VDI desktops have caused work stoppage or slowdown VDI clones have periodically not powered up when called, causing work stoppage

  Which steps should be used to prioritize the administrator's troubleshooting efforts?

  A. Assess resource health on Hardware page Review the Analysis page for memory usage demand Determine the VDI workload-to-host affinity across the cluster

  B. Analyze Alert Pages for a root cause of memory problem Analyze VM table page to access the VM functionality Analyze the VDI Clone properties for possible VDI Workload stress

  C. Check Analysis page for CPU demand Verify VDI workload property for memory subscription Review the Hardware page to determine if the cluster has sufficient RAM

  D. Review Analysis Page for memory use pattern Alert with VDI workload demand Analyze current and future workload in the Capacity Runaway tab for sufficient resources

  Correct Answer: D

• Question 3:

  An administrator is deploying an application that requires maximum I/O throughput for scratch data. The administrator is concerned that the throughput requirement is greater than what can be provided by a single cluster node. What should the administrator do to meet this requirement?

  A. Create a volume group with several virtual disks and attach to the VM

  B. Create a volume group with one virtual disk attached to the VM

  C. Create a virtual disk attached to the VM's PCI interface

  D. Create several virtual disks attached to the VM's virtual SCSI controller

  Correct Answer: A

• Question 4:

  An administrator needs to initiate a new VDI project within a couple of months. Prism Central reports there are no storage resources to accommodate such workloads.

  The administrator sees many powered-off VMs and has the authority to delete test VMs powered off at least for 30 days. Test VMs belong to the Test category.

  Using Prism Central, which steps are required to identify the correct VMs to be deleted?

  A. Use Capacity Runway to filter by Test and Powered-off VMs

  B. Filter VMs list, choose Test category and Inactive under Efficiency

  C. Create a new Scenario selecting Test VMs. filter by uptime

  D. Create a new Project selecting Test VMs, sorting by power state

  Correct Answer: B

• Question 5:

  

  An administrator has two clusters: Site A and Site B. Async DR is configured between the clusters as follows: Site A is the Primary Site

  Site B is the Secondary inactive Site, no VMs running Site A is fully in Production Site B used as Backup/Disaster Recovery

  The customer wants to perform a planned failover between the sites. How should the administrator accomplish this?

  A. Click Activate on the Secondary site within the Data Protection Dashboard

  B. Click Activate on the Secondary site and run deactive NCLI command on Primary site

  C. Choose Migrate on the Secondary site within the Data Protection Dashboard

  D. Choose Migrate on the Primary site within the Data Protection Dashboard

  Correct Answer: D

• Question 6:

  A customer has a four-node cluster and is using Volume Groups to provide storage services to a SQL cluster. In the event of a CVM failure in the cluster, what is the expected IO path of the volume group's iSCSI targets?

  A. vDisk directed at failure CVM are redirected to Data Services IP until CVM is reconnected

  B. vDisk directed to CVM that failed to disconnect and will not reconnect without manual intervention

  C. vDisk directed to failed CVM are redirected to another CVM and automatically reconnect

  D. vDisk directed at failed CVM will disconnect and reconnect when the failed CVM comes back online

  Correct Answer: C

• Question 7:

  A customer needs a DR solution designed around the following requirements:

  There are 8 ms of latency between Sites A and B The administrator needs the shortest RPO/RTO possible Application consistent snapshots are required Use of Nutanix VSS

  Which Data Protection Method should be used?

  A. Async

  B. Metro Availability

  C. Near Sync

  D. Cloud Connect

  Correct Answer: C

• Question 8:

  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?

  A. 0 minutes

  B. 15 minutes

  C. 1 hour

  D. 6 hours

  Correct Answer: B

• Question 9:

  An administrator receives an error indicating that the CVMs in the cluster are not syncing to any NTP servers. An investigation of the issue finds:

  The NTP servers are configured in Prism The time on all CVMs is the same Both the CVMs and AHV hosts are configured for the UTC time zone

  Which two steps can be taken to troubleshoot this issue? (Choose two.)

  A. Confirm that the NTP servers are reachable from the CVMs.

  B. Restart genesis on all CVMs.

  C. On a CVM. run the command a Hash ntpq -pn.

  D. Restart the chronos service on all CVMs.

  Correct Answer: AC

• Question 10:

  An administrator is deploying several new application VMs to a Nutanix cluster. The application is very transactional with a 28/72 random, read/write ratio. What should the administrator do?

  A. Add a minimum of four SSDs to each node to ensure all writes go to the SSDs.

  B. Add a minimum of four virtual disks to each VM, and aggregate them on guest OS level.

  C. Add one large SSD to each node and enable Flash Mode for the VMs.

  D. Add one large virtual disk to each VM. and use it for all application data.
