• Question 32:

  An administrator is patching a production Stretched Cluster using VMware Update Manager. Which statement is accurate?

  A. The witness hosts can be patched using normal patch processes with VMware Update Manager.

  B. Witness hosts cannot be patched or upgraded using VMware Update Manager.

  C. The witness host does not need to be upgraded as there is no data on the node, just metadata.

  D. The witness host must be deleted and a new witness host must be deployed.

  Correct Answer: A

• Question 33:

  A higher level of resiliency has been requested for an existing vSAN Stretched Cluster. A key requirement will be the addition of a third site to protect against a potential double site failure of the two mirrored sites in the stretched cluster. What solution would meet the resiliency requirement?

  A. Replicate to the third site at the VM level using vSphere Replication.

  B. Configure vSAN Stretched Cluster with FTT=2 to replicate to the third site.

  C. Add the third site to the existing vSAN Stretched Cluster.

  D. Replicate to the third site at the vSAN datastore level using Site Recovery Manager.

  Correct Answer: C

• Question 34:

  An infrastructure architect is designing a vSAN Cluster that must satisfy these requirements:

  support storage policies with 2 failures ?RAID-1 (Mirroring)

  support storage policies with 2 failures ?RAID-6 (Erasure Coding)

  virtual machines must maintain compliance with the storage policy rules above when one host is in maintenance mode with full data migration

  What is the minimum number of hosts needed to achieve these design requirements?

  A. 6

  B. 8

  C. 5

  D. 7

  Correct Answer: A

• Question 35:

  Refer to the exhibit.

  

  An administrator is managing a 4-node, hybrid vSAN cluster. One of the hosts in the cluster went offline.

  Referencing the information displayed in the resyncing objects section of the vSAN UI, what is the current state of this cluster?

  A. Offline host reconnected to the cluster and all objects are synchronized.

  B. Objects will be resynchronized when the Object Repair Timer expires.

  C. Resync Throttling has caused data resynchronization scheduling.

  D. Metadata resynchronization is scheduled to occur every 60 minutes.

  Correct Answer: D

• Question 36:

  Refer to the exhibit.

  

  A vSAN Cluster stretched across Data Site 1 and Data Site 2 has a vSAN data network configured with an MTU of 9000. The witness node has been placed in a remote site across a WAN with an MTU of 1500. The vSAN health check, 'vSAN: MTU check (ping with large packet size)', reports a failed ping.

  What two actions could resolve the issue? (Choose two.)

  A. Reduce the MTU from 9000 to 1500 on all vSAN VMkernel interfaces.

  B. Reconfigure the VLAN of the witness traffic to be identical to data nodes.

  C. Configure proper routing from data sites to the witness across the WAN.

  D. Reconfigure WAN link to support an MTU of 9000.

  E. Stretch L2 traffic from WAN to both data sites.

  Correct Answer: AD

• Question 37:

  A vSAN administrator is working on a 4 host homogenous vSAN Cluster that has 2 disk groups per host. One of the hosts needs to be permanently removed and repurposed for some other use. These are the out of order steps which need to be completed:

  1.

  Delete the disk group(s) that reside on the host you want to decommission.

  2.

  Wait for resync traffic to complete and the host to enter maintenance mode.

  3.

  Ensure there is sufficient capacity in the vSAN disk groups to decommission a node.

  4.

  Put the host into maintenance mode with full data migration selected.

  5.

  Move the ESXi host out of the cluster. What is the correct order?

  A. 3, 1, 4, 2, 5

  B. 3, 4, 2, 1, 5

  C. 4, 3, 2, 5, 1

  D. 4, 3, 2, 1, 5

  Correct Answer: B

• Question 38:

  A vSAN administrator wants to implement end-to-end prioritization of vSAN traffic across the network in a shared network infrastructure that is using vSphere Distributed Switches (VDS). Which two can help achieve this objective? (Choose two.)

  A. Configure CoS or DSCP with high priority tag at the VDS and equivalent in the physical network.

  B. Enable jumbo frames for vSAN VMkernel ports and configure LACP for optimal load balancing.

  C. Enable Network I/O Control and allocate higher shares for vSAN traffic.

  D. Configure multiple vSAN VMkernel interfaces to load balance across multiple uplinks.

  E. Enable network resource pool at the VDS level to prioritize vSAN traffic.

  Correct Answer: BC

• Question 39:

  Which is true of the vSAN iSCSI target service?

  A. It is a VMware supported cost effective way to provide shared storage to another hypervisor.

  B. The vSAN default storage policy determines the characteristics of the vSAN iSCSI target service storage objects.

  C. Security is provided through the iSCSI CHAP and Mutual CHAP Authentication methods.

  D. It is a VMware supported solution to provide iSCSI targets to applications that require multiple connections per session (MCS).

  Correct Answer: B

• Question 40:

  Which storage policy can be assigned to virtual machines in a 5-node, all flash vSAN cluster, to provide the highest level of redundancy?

  A. 1 failure

  Correct Answer: B
