Question 9
A 12-node vSAN cluster has been deployed across three server racks in a data center. 
  • There are four nodes in each server rack. 
  • A vSAN fault domain has been configured for each server rack for a total of three fault domains. 
  • All virtual machines in the cluster have the vSAN default storage policy assigned to them. 
  • This policy has not been modified. 
  • vSphere HA is enabled for the cluster. 
  • One of the server racks loses power. 
How does this affect virtual machines running on this cluster? 
  1. Since there are four nodes in each server rack, erasure coding is used to rebuild data that was lost due to the server rack power failure. vSphere HA monitors the rebuild process and powers on all affected virtual machines after the rebuild process is complete.
  2. Virtual machine data in the failed server rack is rebuilt immediately using parity information. vSphere HA powers off and restarts all of the virtual machines to rebalance storage utilization across the cluster. 
  3. All virtual machine data remains accessible. Virtual machines running on nodes in the failed server rack are restarted on nodes in the other two server racks. 
    Virtual machines in the other two server racks continue to run.
  4. Virtual machines running on nodes in the failed server rack remain offline for 60 minutes. Virtual machines in the other two server racks continue to run and are marked "Degraded".
Correct answer: C
Question 10
Which of the listed configurations is a supported vSAN configuration?
  1. Four physical hosts 
    Every host has one vSAN disk group 
    Each vSAN disk group contains one cache device and five capacity devices 
    The vSAN service is enabled on a VMkernel adapter on every host
  2. Three physical hosts 
    Every host has one vSAN disk group 
    Each vSAN disk group contains two cache devices and four capacity devices 
    The vSAN service is enabled on a VMkernel adapter on every host
  3. Four physical hosts 
    Two of the host have one vSAN disk group, the other two hosts are "compute-only" nodes 
    Each vSAN disk group contains one cache device and three capacity devices 
    The vSAN service is NOT enabled on the "compute-only" nodes
  4. Four physical hosts 
    Two of the host have one vSAN disk group, the other two hosts are "compute-only" nodes 
    Each vSAN disk group contains one cache device and three capacity devices 
    The vSAN service is enabled on a VMkernel adapter on every host
