Demo Questions

Question 1
In stretched clusters, what is a benefit of implementing a virtual witness rather than a physical witness?
  1. Reduced vSphere licensing
  2. Shared metadata between separate clusters
  3. Increased vSAN datastore capacity
  4. Increased compute for running VMs
Correct answer: A

Question 2
A storage administrator discovers vSAN is rebalancing components across a cluster randomly and faces degraded performance on the applications. 
What should be done to avoid these issues?
  1. Size at least two disk groups on each node
  2. Maintain a minimum of 10 percent unused capacity
  3. Keep total storage consumption <70 percent
  4. Ensure there is sufficient queue depth on the I/O Controller
Correct answer: A

Question 3
What is the purpose of slack space in vSAN?
  1. Increases overall vSAN capacity
  2. Allows for maintenance and failure operations
  3. Stores vSphere HA heartbeats
  4. Provides vSAN analytic data
Correct answer: B

Question 4
The objects on a 4-node vSAN cluster are assigned a RAID-5 policy. A network outage occurs causing host one to lose connectivity with the rest of the cluster. Seventy-five minutes elapse. 
What is the health state of the objects?
  1. Reduced availability with no rebuild
  2. Reduced availability with no rebuild – delay timer
  3. Non-availability related incompliance [non-compliance]
  4. Reduced availability
Correct answer: D
Question 5
A vSAN 5-node cluster has two sets of VMs, each associated with a separate storage policy. 
  • Group A (Storage Policy: FTT=0)
  • Group B (Storage Policy: FTT=2)
What are two possible results when two hosts in the vSAN cluster fail permanently? (Choose two.)
  1. VMs in Group B will become inaccessible if a third host permanently fails.
  2. vSAN will rebuild data associated with Group A.
  3. VMs in Group A might experience data inaccessibility.
  4. VMs in Goup B might experience data loss.
  5. A host can be put into maintenance mode without impacting VMs in either Group A or B.
Correct answer: CD
Question 6
A vSAN cluster has this configuration:
  • 4 hosts with 1 disk group per host 
  • Each disk group contains 1 cache device and 7 capacity devices 
What are two ways to increase the vSAN datastore storage capacity? (Choose two.)
  1. Add a host to the cluster
  2. Add a cache device to each disk group
  3. Add a capacity drive to each disk group
  4. Replace a cache device with a larger cache device
  5. Add a disk group to each host
Correct answer: AE
Question 7
vCenter Server is offline. 
What are two ways to check the health of a vSAN cluster? (Choose two.)
  1. ESXi system logs on vSAN datastore
  2. vSphere Host Client
  3. esxcli
  4. HCIBench
  5. esxtop
Correct answer: BC

Question 8
What are two purposes of a vSAN storage policy? (Choose two.)
  1. Determine how storage objects are provisioned
  2. Determine vSAN encryption level
  3. Guarantee the required level of service
  4. Enable deduplication and compression
  5. Enable TRIM/UNMAP
Correct answer: AC

Question 9
Which two conditions should be verified before removing the ESXi host from a vSAN cluster? (Choose two.)
  1. Data evacuation is complete.
  2. Encryption is disabled.
  3. ESXi host is in maintenance mode.
  4. Resyncs are running.
  5. All objects are currently healthy.

In a 10-node hybrid vSAN cluster, each node has seven 4TB magnetic disks and one 2TB SSD. 
What is the raw storage capacity of the vSAN datastore?
  1. 140TB
  2. 150TB
  3. 280 TB
  4. 300 TB
