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 3-node All-Flash vSAN cluster has this configuration:

One disk group per host All disk groups have identical make and model disks of an 800GB NVMe SSD cache and 2x 4TB SAS SSDs each An administrator has been tasked with expanding storage capacity by adding one additional disk group with this configuration: 1.6TB SAS SSD cache and 1x 4TB SAS SSDs Assuming all the disks are compliant with the vSAN HCL, which is true?

A. The additional disk group would not be possible as vSAN would not allow it.

B. The additional disk group would work and be fully supported by VMware support.

C. The additional disk group will generate an `Advanced vSAN Configuration in sync' health check warning.

D. The additional disk group would make this cluster an unsupported configuration.

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.

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.

Which two are requirements for Kubernetes cluster virtual machines when leveraging vSphere Cloud Native Storage (CNS)? (Choose two.)

A. configure UEFI firmware

B. Set the Disk Mode to Independent

C. set the disk.EnableUUID advanced setting to TRUE

D. virtual machine hardware version 15 or higher

E. minimum of 4 vCPUs per node

An architect has been asked to design a vSAN Stretched Cluster. The architect will configure Microsoft Active Directory to replicate between a server on Site A (preferred) and a server on Site B (non-preferred). The architect must minimize the amount of raw storage capacity used.

Which storage policy needs to be applied to the Active Directory server on site A?

A. Dual site mirroring

B. None

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 two statements are true about a vSAN Cluster when the vCenter Server managing it is offline? (Choose two.)

A. vSAN health information is available through esxcli commands.

B. vSAN continues to operate and all VMs inherit the default vSAN storage policy.

C. Use a Web browser to monitor vSAN through the vSphere Host Client.

D. Manage and view vSAN health information using RVC commands.

E. vSAN continues to operate, but vSAN performance metrics will be lost.

An administrator is working with an application which has three characteristics:

latency sensitive database striped over multiple virtual disks no application redundancy

Which storage policies meet the VM performance and cluster constraint while protecting against at least 1 failure?

A. RAID 6, Stripe Width 2

B. RAID 1, Stripe Width 2

C. RAID 1, Stripe Width 1

D. RAID 5, Stripe Width 1

Which Kubernetes component must be configured to allow for dynamics provisioning of container volumes on vSAN?

A. vSphere Container Storage Interface driver

B. vSphere Cloud Storage Plugin

C. glusterfs

D. Cinder
