Question 15

An administrator has received an alert indicating that a single capacity device is close to failing within the production vSAN Cluster. The administrator must now complete preemptive maintenance on the vSAN Cluster without impacting the availability of workloads or vSAN File Services.

The following information is known about the vSAN Cluster:

✑ vSAN 7.x Cluster

✑ vSAN node count: 8

✑ De-Duplication and Compression: Enabled.

✑ Encryption: Disabled

Current Utilization: 45%

✑ Disk Groups: 2

✑ Devices per node: 2 x 400 GB SSD, 6 x 1.8 TB SSD

Which three steps should the administrator take to successfully complete the task? (Choose three.)

    Correct Answer: A, B, E

    To preemptively address the potential failure of a capacity device in a vSAN cluster while ensuring no disruption to workloads, the administrator should first place the affected host into maintenance mode. This step ensures that any necessary physical replacement can be performed without impacting the overall system. Next, they should remove the affected disk group from the vSAN cluster and choose the Full Data Migration option to ensure that all data is safely moved to other devices in the cluster. Finally, they should replace the failed disk with a new storage device that is of identical class and capacity, maintaining the integrity and balance of the vSAN environment.

DD&Compression requires to remove the whole disk group. Maintenance mode for replacing replace with similar sized device

dikboyOptions: BEF

I choose B,E,F If you upgrade the capacity device, verify the following requirements: - Verify that the cluster contains enough space to migrate the data from the capacity device. - Place the host in maintenance mode. See Place a Member of Virtual SAN Cluster in Maintenance Mode. "Select the flash capacity device or magnetic disk, and click Remove selected disk(s) from disk group." https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-4E3390C1-6C50-49E5-AEB6-C9BC037979A1.html

In your link it is clearly mentioned that entire disk group must be remove if deduplication and compression is enabled on the cluster...so i will go with ABE

JonesythegreatOptions: BCE

I am going BCE. Technically you shouldn't have to put the host in maintenance mode to replace a disk. When vSAN detects a disk is going to failure it will automatically move that data and stop using that disk. In this case it would stop using the disk group because of compression. See https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.virtualsan.doc/GUID-AA72CA1D-803D-4D1D-87BB-E7D86EC947D2.html calling out when replacing a failed disk group, use the "No Data Migration Option".

I disagree on C. The url you listed lists "No Data Migration" option for FAILED drive. In this question is is talking about drive that is "close to failing". This means that all of the data is still accessible and user should be able to migrate it off before the disk fails. We also don't want to "impact the availability" of the workload, which means that we don't want vSAN to start rebuilding data only 60 min after the disk group is removed.

ABF答案是对的

huijianqian

capacity device is close to failing

huijianqianOptions: BCE

bce. e-Duplication and Compression: Enabled.

huijianqian

capacity device is close to failing ，so ABF
