質問 1：
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.

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. Configure proper routing from data sites to the witness across the WAN.
C. Reconfigure the VLAN of the witness traffic to be identical to data nodes.
D. Stretch L2 traffic from WAN to both data sites.
E. Reconfigure WAN link to support an MTU of 9000.
正解：A,E

質問 5：
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 section of the vSAN UI, what is the current state of this cluster?
A. Objects will be resynchronized when the Object Repair Timer expires.
B. Resync Throttling has caused data resynchronization scheduling.
C. Offline host reconnected to the cluster and all objects are synchronized.
D. Metadata resynchronization is scheduled to occur every 60 minutes.
正解：D

質問 6：
An administrator Is reassessing subnet use in preparation for migrating existing vSAN Clusters to a new subnet.
Which steps should the administrator perform to ensure all VMs remain online during the vSAN network subnet migration?
A. Place the hosts Into maintenance mode and update the IP addresses of the current vSAN VMkernel ports to the new subnet.
B. Migrate the VMs using Storage vMotion off the vSAN datastore and rebuild a new vSAN Cluster using the new subnet.
C. Add a second VMkernel port on the new subnet for all hosts and remove original vSAN VMkernel ports.
D. Migrate current vSAN VMkernel ports to a distributed switch and enable vSphere Network I/O Control.
正解：D

質問 7：
An administrator is planning to upgrade from vSAN 6.6 to a newer version. Which is recommended for this upgrade?
A. Perform a rolling upgrade of the hosts via vSphere Update Manager after upgrading vCenter.
B. From the command line, turn multicast off in order to migrate to unicast mode.
C. vSAN VASA Providers must be changed to be internally managed prior to the upgrade.
D. Certificates used by VASA must be upgraded on vSphere prior to the upgrade.
正解：A

質問 8：
An administrator would like to put a vSAN host in an existing vSAN Cluster in maintenance mode. vMotion is configured and DRS is set to Fully Automated and all other advanced settings are their defaults.
The administrator uses this PowerCU command:
Set-VMHost -VMHost "esxi-hoat01.corp.local" -State "Maintenance"
What is the default behavior?
A. Virtual machines will not be live migrated to another host not in maintenance mode and storage objects will be migrated if it is required to be accessible.
B. Virtual machines will be live migrated and all storage objects residing on this host will migrate to another host that is not in maintenance mode.
C. Virtual machines will be live migrated to another host not in maintenance mode and storage objects will not migrate regardless of policy and state.
D. Virtual machines will be live migrated to another host not in maintenance mode and storage objects will be migrated if it is required to be accessible.
正解：B
