Question 123

Refer to the exhibit.

A Cisco engineer is configuring a next-generation Cisco HyperFlex HX data platform with 2 x Cisco UCS 6248UP fabric interconnects, 8 x Cisco HX-Series HX240c-M4SX servers, plus 8 x Cisco UCS B200-M4 blade servers, Cisco UCS 5108 blade chassis, and Cisco UCS 2204XP fabric extenders. The solution is configured with HX Release 4.5(2a) using VMware ESXi 7.0 U2. After the engineer migrates all customer VMs to the new solution platform, the engineer decides to create HX Native snapshots for all the VMs. The engineer performs the operation and notices that some of the VMs are not creating snapshots. What is the most probable reason that the HX Native snapshots are not created?

    Correct Answer: A

    VMs or resource pools with duplicate names within the HX Data Platform vCenter are not supported and cause HX native snapshots to fail. This is because the snapshot process requires unique identifiers for each VM to correctly maintain and manage snapshot data. Duplicate names can lead to conflicts and errors in the snapshot creation process, preventing it from completing successfully.

Discussion
WasamelaOption: B

The answer is B, "The source disk is thick provisioned" as when this happens all the storage space is allocated upfront, regardless of whether it's being used or not, leading to inefficiencies and limitations when creating the Snapshots.

FcpoultryOption: C

On second thoughts, perhaps "C"is correct as we are talking about VMs. Suspended VMs - Creating the first HX native snapshot and the HX SENTINEL snapshot on VMs in a suspended state is not supported. https://www.cisco.com/c/en/us/td/docs/hyperconverged_systems/HyperFlex_HX_DataPlatformSoftware/AdminGuide/5-0/b-hxdp-admin-guide-5-0/m_hxdp_snapshots.html#id_13130

FcpoultryOption: A

Duplicate names - VMs or Resource Pools with duplicate names within the HX Data Platform vCenter are not supported and cause HX native snapshots to fail. This includes parents and children within nested resource pools and resource pools within different vCenter clusters. https://www.cisco.com/c/en/us/td/docs/hyperconverged_systems/HyperFlex_HX_DataPlatformSoftware/AdminGuide/5-0/b-hxdp-admin-guide-5-0/m_hxdp_snapshots.html#id_13130
