Question #6 (Topic: Topic 1)
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?
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.
Answer: C
Question #7 (Topic: Topic 1)
During planned maintenance of a four-node vSAN cluster, an outsourced IT contractor accidentally removed a 2.5" SSD cache disk from one of the vSAN nodes.
The storage policy has been configured with FTT=1 RAID 1, and the disk management UI marked the disk group as absent.
Which remediation steps should the administrator select to ensure VMs become compliant with the storage policy as soon as possible?
The storage policy has been configured with FTT=1 RAID 1, and the disk management UI marked the disk group as absent.
Which remediation steps should the administrator select to ensure VMs become compliant with the storage policy as soon as possible?
A. replace the SSD cache disk > rescan > add disk back in disk group
B. enter host in maintenance > remove from disk group > shutdown host > replace disk > power on host
C. remove disk group > enter host in maintenance > fully evacuate all data > exit maintenance
D. vSAN Health Check > retest > object health > repair objects immediately
Answer: A
Question #8 (Topic: Topic 1)
A 3-node All-Flash vSAN cluster has this configuration:
✑ One disk group per host
✑ All disk groups have identical make & 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?
✑ One disk group per host
✑ All disk groups have identical make & 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.
Answer: D
Question #9 (Topic: Topic 1)
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.
Answer: AE
Question #10 (Topic: Topic 1)
Which two statements regarding networking are true for a vSAN Stretched Cluster? (Choose two.)
A. A 5ms RTT or less is required between the data sites.
B. The vSAN data network must communicate with the vSAN witness host.
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 Stretched Layer 2 network is required at the vSAN data sites and at the witness site.
Answer: AD
