An architect is designing network high availability for a new vSAN Cluster.
Which is a supported configuration for this design?
D18912E1457D5D1DDCBD40AB3BF70D5D

• A.  Use LACP on the distributed switch with a route based on IP hash algorithm.
• B.  Configure multicast to use two separate network interfaces for vSAN traffic.
• C.  Create an additional TCP/IP stack within the cluster and specify vSAN type.
• D.  Create multiple VMkernel adapters on the same subnet for vSAN.

An architect has been asked to plan the Impact of a storage policy change to one of the production All-Flash based vSAN datastores. The change will reduce the failures to tolerate value from 2 to 1 for objects with a RAID-1 (Mirroring) layout in the existing policy. This change will be applied to multiple VMs.
Which statement is correct in this scenario?

• A.  There will be no objects rebuilt that impact performance.
• B.  FTT-2 requires another change to apply a RAID-6 configuration.
• C.  The policy will need to be recreated and applied with an additional tag.
• D.  There will be an object rebuild impact on performance.

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

An All-Flash vSAN cluster has 4-nodes with this disk group composition on each host:
* 1 x 800 GB SAS SSD
* 6 x 3.84 TB SATA SSD
An administrator observes that in an All-Flash cluster, the Write
Buffer Free Percentage is consistently low. As a result there is increased latency experienced by the workloads.
Which remediation steps will resolve this issue?

• A.  Replace the existing cache device with a larger cache device.
• B.  Add a second cache device to the same disk group to increase the caching size.
• C.  Add a second disk group with a new cache device and distribute the capacity disks equally.
• D.  Modify advanced vSAN configuration parameters to utilize the complete 800 GB for caching.

A vSAN disk group contains one cache drive and four capacity drives. A drive that belongs to this disk group has failed. The entire disk group containing the failed drive Is offline.
What are two possible reasons the entire disk group Is offline? (Choose two.)

• A.  Data-at-rest encryption is enabled for the disk group.
• B.  Deduplication and compression is enabled on the cluster.
• C.  Two capacity dnves in the disk group are offline.
• D.  The failed drive is configured as a cache drive for the disk group.
• E.  RAID-5/6 (Erase Coding) is one of the failure tolerance methods in use.
