• Question 53:

  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?

  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 the cluster 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 54:

  An administrator is managing multiple Windows and Linux VMs connected to Nutanix Volumes. The Linux VMs are experiencing intermittent connectivity issues. The Windows VMs do not experience the same issue. Which option should the administrator use to resolve this issue?

  A. Utilize Jumbo Frames

  B. Add additional disks to the Volume Group

  C. Set the SCSI timeout value to 60

  D. Utilize a separate subnet for the Linux VMs

  Correct Answer: C

• Question 55:

  An administrator needs to migrate workloads from a Nutanix cluster running VMware ESXi to Nutanix AHV. The migration process needs to be completed in multiple VM groups and support roll back in case any problems are found during user acceptance testing.

  Which action should the administrator perform?

  A. Use Cross Hypervisor DR to replicate VMs from ESXi to AHV

  B. Use VMware Converter

  C. Use Nutanix one-click cluster conversion from ESXi to AHV

  D. Use storage live migration

  Correct Answer: C

• Question 56:

  An administrator receives an alert in Prism indicating that interface eth2, on an AHV host is receiving many CRC errors. After togging into the problematic host, the following command is run to show the indicated output: What is causing this issue?

  

  

  A. Incorrect link speeds on the switch

  B. The interface is incorrectly configured with Jumbo Frames

  C. A misconfigured bond

  D. A physical layer network problem

  Correct Answer: B

  Explanation: Ref: rx_crc_errors are caused either by faults in layer 1 (in the past, we have seen failed twinax cables and incorrect types of fibre being used), or issues with jumbo frames on the network. In an environment with 10 Gig switches that use cut-through forwarding (Cisco Nexus, Arista, Cisco devices using IOS default to Store and Forward switching), any packets that come into the switch will get forwarded out the destination interface once the switch has read the destination MAC address. If that packet has an MTU over what is configured on the interface, it will cut off the packet at the designated MTU, causing the server to receive a malformed packet, which will throw a CRC error. If you have a layer 1 issue, you will see rx_crc_errors, not on all but one or two nodes.

• Question 57:

  An administrator deletes a large amount of data from a Volume Group presented to a Linux VM. The administrator notices that the deleted data has not been reclaimed as usable storage. What action should be taken to reclaim the storage capacity?

  A. Shrink the Volume Group that is associated with the Linux VM

  B. Unmount the Volume Group and then Remount the Volume Group

  C. Enable the unman operation on the Linux VM

  D. Run Defrag on the Linux VM

  Correct Answer: B

• Question 60:

  A customer has NearSync configured. When the administrator tries to restore a snapshot from 3 minutes ago, it is not available. The snapshots are happening at 15-minute intervals instead of at the 5-minute configured interval. When the protection domain was initially set up, the snapshots were happening at the expected 5-minute interval.

  What should the customer do to enable the snapshots to happen at the expected interval?

  A. Utilize Metro Availability to meet this requirement

  B. Change the protection domain to use Async DR

  C. Fix a connectivity issue because the protection domain reverted to Async

  D. Configure the protection domain to take snapshots on 15-minute intervals

  Correct Answer: C
