Exam 5V0-21.21 topic 1 question 38 discussion

Actual exam question from VMware's 5V0-21.21
Question #: 38
Topic #: 1
[All 5V0-21.21 Questions]

A company has engaged a consultant to upgrade an existing vSAN cluster to vSAN 7.0 U1.
During the discovery phase, the consultant found the following information about the existing environment:
✑ The VMware vCenter Server has recently been upgraded from VMware vSphere 6.7 U3 to version 7.0 U1.
✑ The vSAN Cluster was recently expanded with identical hardware specification, but from a different hardware vendor.
The hardware for each vSAN node is listed on the vSAN Compatibility Guide (VCG) for vSAN 7.

✑ The vSAN Cluster has the following configuration:
- vSAN version: 6.6.1
- Number of vSAN nodes: 10
- Encryption: enabled
- Deduplication and Compression: enabled
- vSAN Capacity Utilization: 60%
✑ Each vSAN node has the following configuration:
- VMware vSphere ESXi version: 6.5 Update 3
- CPU: 2 processors, 20 cores
- RAM: 768GB RAM.
- Disk: 2 Cache SSDs and 6 Capacity SSDs
- Network: 4 x 10GbE
Which three recommendations should the consultant make to ensure all data remains protected in the event of a vSAN failure? (Choose three.)

  • A. The Full data migration maintenance mode option must be chosen to protect the data during the upgrade.
  • B. The Ensure accessibility, migration maintenance mode option must be chosen to protect the data during the upgrade.
  • C. The upgrade process should be completed using host upgrade baselines in VMware vSphere Lifecycle Manager (vLCM).
  • D. The vSAN nodes should be upgraded to vSphere ESXi 7.0 U1.
  • E. The upgrade process should be completed using images in VMware vSphere Lifecycle Manager (vLCM).
  • F. The vSAN nodes should be upgraded to vSphere ESXi 6.7 U3.

I think ACD https://kb.vmware.com/s/article/2146381 To ensure protection : full data migration Migration to same version as vCenter. I think we can't use images on different hardware vendor.

Ensure Accessibility: It has the potential to impact VM data availability if you were to have another failure (component or hosts) within that maintenance timeframe.

Selected Answer: BCD
BCD for sure, I just finished vSphere environment upgrade and used BCD, No way A as it is take for ever and no need for FULL data migration, when upgrading vSAN Node - esxi host it hardly takes 10 minutes using baseline image and if you enable quick boot even much less and hence the delay timer repair of 60 minutes is far more than enough but you have the option to increase it to whatever you want then when done revert it back as per VMware recommendation. None of the links provided by aziza12 and Khlalmeety prove B over A is correct.. Full data migration is when you permanently taking the host offline as per this definition from VMware Full Data Migration This option moves all of the vSAN components from the host entering maintenance mode to other hosts in the vSAN cluster. This option is commonly used when a host will be offline for an extended period of time or permanently decommissioned.

ACD. Full data migration for upgrades: https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.virtualsan.doc/GUID-521EA4BC-E411-47D4-899A-5E0264469866.html Upgrade a cluster: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan.doc/GUID-ABABC0DF-2519-4C8F-A5B1-2AECF86247AB.html

Sorry BCD. Ensure Accessibility NOT Full Data Migration.

A is correct because, whether it will take forever or not, the question specifically asks to make sure the data is protected. Time is not a factor. C is correct due to different hardware vendors, so you can't use an image. D is correct because it is the same version as the vCenter.

Selected Answer: ACD
A - Because the question calls for data to be protected in the event of a vSAN failure, so full migration. C - From experience, I've used host upgrade baselines dozens of times for ESXi upgrades. I do import an image to do it, but I don't think this should be confused with "E" -- not sure what that's about. D - Always upgrade vCenter first (which they have), then ESXi, then vSAN... well, there's a lot more to it, but you don't want your hosts being behind vSAN version as the hosts are what are keeping vSAN up and running.

Still same answer, but clarification about "E" -- I assume that we don't choose that because some components are from a different vendor.

bcd, theres no full data migration nessecary - imagine the node contains 40TB of data. An update would take hours just to evacuate the node

A: To "ensure" protection - i.e. to take every precaution to guarantee data is protected (doesn't matter if ESXi upgrades only take 10 mins - you have to be risk-averse), use Full Data Migration C: vLCM images are only applicable to ESXi v7.0 and higher, so we must use host upgrade baselines: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere-lifecycle-manager.doc/GUID-B54663AB-B1D1-4E87-8B8C-76FF2998A477.html D: Upgrade hosts to ESXi v7 U1, since the requirement was to go to vSAN v7 U1

The capacity utilization is %60 for 10 nodes so if use full data migration, utilization would be %66 so the capacity is OK for full data migration, hence, for more safe upgrades need to do full data migration... and from 6.5 U3 to 7.0 u1 is OK, so I think the answer should be ACD

BCD, there is no full migration necessary. A direct upgrade from 6.5 to 7.0 is also possible. A VSAN upgrade then is nothing more that to upgrade the disk format.
