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

Which two statements are true about enabling deduplication and compression on an All-Flash vSAN cluster with data? (Choose two.)

A. On-disk format version 3.0 or later is required to support deduplication and compression.

B. This can be enabled through storage policies and does not require any data migration.

C. Deduplication and Compression cannot be enabled on an existing vSAN datastore with data.

D. Move one host at a time to maintenance mode and enable deduplication and compression.

E. This requires data evacuation and disk format upgrade of all the disk groups.

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.

A vSAN Cluster stretched across Data Site 1 and Data Site 2 has a vSAN data network configured with an MTU of 9000. The witness node has been placed in a remote site across a WAN with an MTU of 1500. The vSAN health check, 'vSAN: MTU check (ping with large packet size)', reports a failed ping.

What two actions could resolve the issue? (Choose two.)

A. Reduce the MTU from 9000 to 1500 on all vSAN VMkernel interfaces.

B. Reconfigure the VLAN of the witness traffic to be identical to data nodes.

C. Configure proper routing from data sites to the witness across the WAN.

D. Reconfigure WAN link to support an MTU of 9000.

E. Stretch L2 traffic from WAN to both data sites.

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.

Three months ago, an administrator deployed vRealize Operations Manager from vCenter to manage his newly deployed four-node vSAN 6.7 All-Flash cluster. What must the administrator do to continue using vRealize Operations Dashboards for vSAN?

A. Reconfigure the vSAN cluster.

B. Upgrade vRealize Operation Manager.

C. Apply the correct license to the vSAN cluster.

D. Reconfigure the vRealize Operations Manager.

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 company is using vSAN Data At Rest Encryption. vCenter is placed on a separate management cluster with external storage. The external storage system has suffered from a disk error and the vCenter Server restore from backup has been

unsuccessful, due to media errors.

Considering the scenario, which statement is true?

A. All encrypted disk groups become unmounted and remain offline until vCenter Server is back online.

B. The data within the vSAN datastore is lost, if the hosts are powered off.

C. The VMs on the vSAN datastore need to be migrated to another datastore as quickly as possible to prevent data loss.

D. A new vCenter can be deployed using the existing KMS profile and associated with the existing vSAN encrypted clusters.

A healthy vSAN Stretched Cluster has the existing vSAN Witness Host swapped for a new vSAN Witness Host using the "Change Witness Host" wizard. If the administrator takes no further action, which two does the vSAN Health Check report show? (Choose two.)

A. Performance Service

An administrator has been tasked with the shutdown process of one of the nodes in a 4-node vSAN Cluster, in order to replace a motherboard. The administrator must select the correct maintenance mode option to ensure all objects remain compliant with the vSAN Default Storage Policy. No changes have been made to this policy.

Which maintenance mode option should the administrator select?

A. Allow Reduced Redundancy

B. Ensure Accessibility

C. Full Data Migration

D. No Data Migration
