When designing a vSAN Cluster, which three should be considered when sizing a vSAN datastore? (Choose three.)

A. Storage Policy or Policies to be used

B. capacity device queue depth

C. vSAN Slack Space

D. cache disks with 10% of the Disk Group

E. On-Disk Format overheard

F. endurance level of capacity disk used

A failed storage controller has two vSAN disk groups attached. The components contained on the drives in those disk groups are marked Degraded. vSAN reports that some objects do not comply with their assigned storage policy. How is the compliance issue resolved?

A. Initiate a proactive rebalance to force component repairs.

B. Degraded components are repaired after CLOM Repair Delay Timer expires.

C. Rebuilding of the degraded components starts immediately.

D. Storage policies must be reapplied to all affected objects.

An administrator observes this health check warning:

Controller firmware is VMware certified

They proceed to update the latest firmware on the Storage Controller. After a successful firmware upgrade, the same health check alert continues to display.

Which statement is true?

A. Controller is not VMware certified and hence any firmware version displays a warning.

B. The recently installed firmware is yet to be certified and included in VMware Compatibility Guide.

C. The VMware vSAN Health Service needs to be restarted for changes to take effect.

D. The alert can be ignored and silenced, since the firmware is newer than the recommended firmware.

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.

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.

An architect is designing network high availability for a new vSAN Cluster. Which is a supported configuration for this design?

A. Use LACP on the distributed switch with a route based on IP hash algorithm.

B. Create multiple VMkernel adapters on the same subnet for vSAN.

C. Configure multicast to use two separate network interfaces for vSAN traffic.

D. Create an additional TCP/IP stack within the cluster and specify vSAN type.

A major upgrade of the ESXi code on an existing vSAN cluster was just completed. Upon logging on to the vSphere Web Client, the vSphere administrator encounters UI timeouts on vSAN specific menus. What could cause this?

A. vSphere Update Manager is offline.

B. vSAN Performance Service is offline.

C. vCenter Server has yet to be upgraded.

D. vSAN on-disk format has yet to be upgraded.

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 PowerCLI command:

Set-VMHost -VMHost "esxi-host01.corp.local" -State "Maintenance"

What is the default behavior?

A. 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.

B. 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.

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 not be live migrated to another host not in maintenance mode and storage objects will be migrated if it is required to be accessible.

Which step can be avoided when replacing a capacity tier device on a controller with passthrough mode and support for hot-plug?

A. Shut down the host.

B. Add the new disk to the disk group.

C. Remove the disk from the disk group.

D. Replace the physical drive.

A customer environment includes:

4-node vSAN cluster

5 SQL servers with an OS virtual disk and database virtual disk

Current policy uses the vSAN Default Storage policy

A vSAN administrator has created a new policy with fault tolerance method of Erasure Coding with Failures to tolerate equal to 1. The administrator will apply this new policy to the OS disk only.

Considering this scenario, which two statements are true? (Choose two.)

A. The policy can't be applied as there are not enough nodes to comply with the policy.

B. The object tree will have to be rebuilt when the policy is applied.

C. vSAN policies can only be applied to entire VMs.

D. This policy will require additional transitional space, until all objects are recreated.

E. The policy will result in size reduction and only will require 1.5x space instead of 2x.
