質問 3:
An All-Flash vSAN cluster has 4-nodes with this disk group composition on each host:
* 1 x 800 GB SAS SSD
* 6 x 3.84 TB SATA SSD
An administrator observes that in an All-Flash cluster, the Write
Buffer Free Percentage is consistently low. As a result there is increased latency experienced by the workloads.
Which remediation steps will resolve this issue?
A. Add a second cache device to the same disk group to increase the caching size.
B. Replace the existing cache device with a larger cache device.
C. Modify advanced vSAN configuration parameters to utilize the complete 800 GB for caching.
D. Add a second disk group with a new cache device and distribute the capacity disks equally.
正解:C
質問 4:

B. latency between sites
C. geographical distance
D. bandwidth between sites
E. number of objects
正解:C,D,E
質問 5:
A hardware 10 controller manufacturer has released a new version of firmware which brings performance improvements to the controller that the vSAN disk group is currently using. The administrator would like to upgrade to the new firmware version.
Which action should the administrator perform?
A. Check against the vSAN Compatibility Guide that this new firmware version Is certified and Install it with any certified driver.
B. Install the latest version of vSphere before upgrading to the newest version of firmware.
C. Install the new firmware as soon as possible after testing in his/her lab to take advantage of the performance improvements.
D. Check against the vSAN Compatibility Guide for the correct certified firmware and driver combination and upgrade both firmware and driver.
正解:C
質問 6:
An administrator needs to perform an urgent maintenance activity on a host that is part of a 3-node vSAN cluster. All the disk groups in the cluster are balanced. They need to choose a maintenance mode option to ensure:
*There is no downtime to any of the virtual machines running in the cluster
*Virtual Machine accessibility is maintained
*No data is left on the host that could possibly cause data loss
Which statement is true if the administrator chooses 'Ensure accessibility' as the maintenance mode option?
A. Data Migration is minimized even if VM becomes non-compliant with its storage policy.
B. All data on the host going into maintenance mode will be evacuated.
C. Only VMs will be migrated with vMotion and no data migration will occur.
D. All VMs and data on host will be migrated to ensure that there is no data loss.
正解:A
質問 7:
A vSAN all-flash environment with these host specifications has reported high network latency, write latency, and faces degraded performance:
* One 1Gbps (vSAN, vMotion Traffic)
* One 1Gbps (Management, Fault Tolerance traffic)
Based on the specifications of each host, what is recommended to resolve the issue?
A. collapse all traffic into one 1Gbps NIC
B. change stripe width to 12
C. collapse all traffic shared under two 10Gbps NICs
D. change MTU to 9000
正解:C
質問 8:
Refer to the exhibit.

An administrator is managing a 4-node, hybrid vSAN cluster. One of the hosts in the cluster went offline.
Referencing the information displayed in the section of the vSAN UI, what is the current state of this cluster?
A. Objects will be resynchronized when the Object Repair Timer expires.
B. Resync Throttling has caused data resynchronization scheduling.
C. Metadata resynchronization is scheduled to occur every 60 minutes.
D. Offline host reconnected to the cluster and all objects are synchronized.
正解:C
