• Question 57:

  An administrator is notified that a bare metal database server is down. This database server is being served storage using a Nutanix Volume Group. Upon investigating, the administrator finds that the disks in the database server that map to the vDisks in the volume group have gone offline.

  What is causing this issue?

  A. The Volume Group Load Balancer has been disabled.

  B. Port 9443 is blocked in the server firewall.

  C. Port 3260 has been blocked in the server firewall.

  D. A CVM serving the Volume Group has gone offline.

  Correct Answer: D

• Question 58:

  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 59:

  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
