• Question 91:

  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 thefollowing:

  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?

  A. Expanse the cluster by adding 3 additional nodes per rack, 9 nodes total.

  B. Expanse the cluster by adding 2 additional nodes per rack, 6 nodes total.

  C. Expanse thecluster by adding 9 nodes to a new 42U rack

  D. Expanse the cluster by adding 8 nodes to a new 42U rack

  Correct Answer: A

• Question 92:

  An administrator deploys Exchange on a Nutanix cluster. The administrator creates two containers with RF2 configuration:

  One container for Exchange

  One container for the other VMs

  The Exchange VM isexperiencing I/O performance issues.

  Which changes to Storage Optimization should be used on the Exchange container to enhance I/O performance?

  A. No data reduction

  B. Post process Deduplication only

  C. Inline compression and EC-X

  D. Inline compression andDeduplication

  Correct Answer: A

• Question 93:

  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?

  A. 1. On the remote site, deactivate the Protection Domain using ncli

  2. On the primary site, select theProtection Domain and dick migrate

  B. 1. On the remote site, promote the Protection Domain

  2. On the primary site, change the Protection Domain state from Decoupled to Disabled 3 Enable the original primary site as remote site

  C. 1. On the prima7 site,suspend replications

  2.

  On the remote site, deactivate the Protection Domain using ncli

  3.

  On the remote site, migrate the protection domain back to the primary site

  D. 1 On the remote site, restore the snapshots from the Protection Domain

  2. On the remote site, select the Protection Domain and migrate to the primary site

  Correct Answer: A

• Question 94:

  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 sitewithin the Data Protection Dashboard

  Correct Answer: D

  Correct Answer: A

• Question 96:

  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 toprioritize 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 theHardware 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
