Questions 4

An All-Flash vSAN cluster has 4 nodes with this disk group composition on each host:

1 × 800 GB SAS SSD

6 × 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. Add a second disk group with a new cache device and distribute the capacity disks equally.

B. Add a second cache device to the same disk group to increase the caching size.

C. Modify advanced vSAN configuration parameters to utilize the complete 800 GB for caching.

D. Replace the existing cache device with a larger cache device.

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).

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.
