Demo Questions

Question 1
A single disk in a vSAN disk group suffers from an unrecoverable hardware failure. This causes vSAN to set the health status for all disks in the group to Permanent disk loss, indicating disk failure. 
Assuming all other disks have not suffered from a hardware failure, why would vSAN mark all disks in the group as failed?
  1. The vSAN disk management service has failed.
  2. The affected vSphere host is offline.
  3. The key management server is offline.
  4. Deduplication and compression are enabled on the vSAN cluster.
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 3-node vSAN cluster will take which two actions, when a drive is physically removed from a vSAN node? (Choose two.)
  1. Marks all components on that device as absent
  2. Marks all components on that device as degraded
  3. Waits for the configured delay timer before rebuild
  4. Marks all components on that device as stale
  5. Starts component rebuild immediately
Correct answer: AC

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
An organization is no longer compliant with security requirements because a vSphere administrator disabled encryption on a vSAN cluster. 
Which vCenter Server role ensures only authorized vSphere administrators have access to encryption functionality?
  1. Administrator
  2. Read-only
  3. No cryptography administrator
  4. No access
Correct answer: C

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

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.
Correct answer: CE

Question 10
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
