質問 2

How does vSAN respond when a vSAN drive is pulled from a server chassis or a host if a vSAN cluster fails without warning?

（A）Components on the affected device(s) are marked as healthy. vSAN will attempt to rebuild the components after the VSAN.ComponentRecovery timer, which is set to 60 minutes by default, expires.

（B）Components on the affected device(s) are marked as stale. vSAN will attempt to rebuild the components after the VSAN.ComponentRecovery timer, which is set to 90 minutes by default, expires.

（C）Components on the affected device(s) are marked as inaccessible. vSAN will attempt to rebuild the components the next time a host enters maintenance mode.

（D）Components on the affected device(s) are marked as absent. vSAN will attempt to rebuild the components after the VSAN.ClomRepairDelay timer, which is set to 60 minutes by default, expires.

（E）Components on the affected device(s) are marked as degraded. vSAN will attempt to rebuild the components the next time a host enters maintenance mode.

質問 3

Consider the following scenario in a vSAN cluster that contains six hosts:
* All virtual machines are assigned the vSAN Default Storage Policy, which has not been modified.
* Deduplication and compression are not enabled.
* Every vSAN disk group in the cluster contains one cache device and five capacity devices What happens when a capacity devices transmits SCSI sense code errors and fails?

（A）All components on the affected device are marked "offline". vSAN attempts to rebuild the components on other healthy devices in the cluster after 60 minutes by default.

（B）All components on the affected device are marked "degraded". The host containing the affected drive is placed into maintenance mode using the 'ensure accessibility' option.

（C）The host containing the affected drive is placed into maintenance mode using the "ensure accessibility" option. An administrator must log into the vSphere Web Client and click Repair Objects immediately.

（D）All components on the affected device are marked "degraded". vSAN attempts to rebuild the components on other healthy devices in the cluster without delay.

質問 4

Which statement is true about vSAN three-node cluster configuration?

（A）A storage policy with a RAID-5/6 erasure coding rule cannot be applied to a virtual machine object.

（B）Three-node clusters can tolerate a maximum of 2 host failures as long as there are at least 2 disk groups in each host.

（C）Three-node clusters can tolerate a maximum of 2 host failures.

（D）A storage policy with a deduplication and compression rule can be applied to a virtual machine object.

質問 5

When using vSAN in a two-node direct connect configuration, how do data nodes communicate with the vSAN witness appliance?

（A）If the data node management VMkernel interfaces that are tagged for management traffic only have connectivity with the vSAN witness, they will provide communication with the vSAN witness.

（B）An alternate VMkernel interface that has connectivity to the vSAN witness must be tagged with a vSAN traffic type of "witness" VM

（C）The vCenter Server acts as a proxy between data nodes and the vSAN witness.

（D）Two-node direct connect does NOT require connectivity to the vSAN witness appliance.

質問 6

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?

（A）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.

（B）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.

（C）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.

（D）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".
