An administrator receives an alert for vCenter being unavailable. With vCenter running on vSAN, the administrator wants to know if any other VMs are impacted. What command can an administrator run to determine the overall health of the vSAN objects?

• A.esxcli vsan storage list
• B.esxcli vsan health cluster list
• C.esxcli vsan errands timemachine get
• D.esxcli vsan cluster get

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.Add a second VMkernel port on the new subnet for all hosts and remove original vSAN VMkernel ports.
• B.Migrate current vSAN VMkernel ports to a distributed switch and enable vSphere Network I/O Control.
• C.Migrate the VMs using Storage vMotion off the vSAN datastore and rebuild a new vSAN Cluster using the new subnet.
• D.Place the hosts Into maintenance mode and update the IP addresses of the current vSAN VMkernel ports to the new subnet.

Reference the exhibit.

A university campus has a site topology illustrated in the exhibit. Adjacent connected buildings are connected with a single 40gb layer 3 network with a RTT of 0.6ms as depicted by each line. An architect wants to configure a fault domain in each building.
What would the architect need change in order to implement a fully supported vSAN Cluster?

• A.Decrease the existing RTT between the existing links by 0.1ms or more.
• B.Enable IPv6 networks across all buildings for vSAN connectivity.
• C.Enable a single Layer 2 network across all buildings for vSAN connectivity.
• D.Add an additional link to the existing adjacent links to make it redundant.

Which two statements regarding networking are true for a vSAN Stretched Cluster? (Choose two.)

• A.The vSAN data network must communicate with the vSAN witness host.
• B.PIM is required for stretched vSAN clusters.
• C.A 5ms RTT or less is required between the data sites.
• D.A Stretched Layer 2 network is required at the vSAN data sites and at the witness site.
• E.A Stretched Cluster can use Layer 2 or Layer 3 communication for the vSAN network.

Which is true of the vSAN iSCSI target service?

• A.Security is provided through the iSCSI CHAP & Mutual CHAP Authentication methods.
• B.It is a VMware supported solution to provide iSCSI targets to applications that require multiple connections per session (MCS).
• C.The vSAN default storage policy determines the characteristics of the vSAN iSCSI target service storage objects.
• D.It is a VMware supported cost effective way to provide shared storage to another hypervisor.
