Exam 5V0-22.21 topic 1 question 18 discussion

C. The configuration must meet the same latency and bandwidth requirement as local vSAN. E. Either Layer 2 and Layer 3 communications can be used.

E - No brainer. So C or D for the other choice? C is a recommendation for HCI Mesh only. It's a requirement for Stretched Cluster only. So, D&E

Here is the whole question: A site administrator wishes to implement HCI Mesh between two clusters on vSAN 7.0 U2 that are in geographically separate sites and which are administered within a single datacenter. Which two requirements should the vSAN administrator consider in order to accomplish this goal? All the documentation I have read points to C and D being the answers. Encryption is disabled when HCI Mesh is selected in the config, and the Compatibility check makes sure the latency is below 5000 microseconds.

The only listed requirements are latency and encryption. The other options aren't requirements but are supported options. A is a supported network topology that can reduce latency, but is not a HCI mesh requirement. B is a supported configuration to reduce latency if using a shared NIC for traffic, but again, not required. E is supported, but also no a requirement. C and D are the only requirements.

In an HCI Mesh Architecture, since VM’s living in one cluster may be using storage resources in another cluster, the network communication requirements will need to meet adequate levels of performance to not hinder the workloads.  Latency between the clusters will add to the effective latency seen by the VMs using resources across a cluster.  The recommendations are as follows:

Encryption in transit is not supported. While nothing said regarding network requirements. And E for sure https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan.doc/GUID-9113BBD6-5428-4287-9F61-C8C3EE51E07E.html

2 network requirements is :A a leaf spine topology and C same latency as local VSAN . vsan student guide page 139 ---- correct answer A,C

There is a missing paragraph describing a situation where a vSAN administrator needs to deploy a vSAN HCI Mesh between two geographically separate sites. I answered C and E.

even if the exhibit is missing the options is talking about HCI Mesh networking requirements and recommendations, in which case the correct answer is A and C. They are the only 2 options that make sense

This question is incomplete, probably an exibihit is missing...

There could be, but based on supplied answers BE and reference. This could be correct as per this also - https://core.vmware.com/resource/vmware-vsan-hci-mesh#section3 which points out - Use of vSphere Distributed Switches (vDS) is needed to allow for proper bandwidth sharing via NIOC...Advantages of NIC Teaming: To utilize NIC teaming, two or more network adapters must be uplinked to a virtual switch. The main advantages of NIC teaming are: Increased network capacity for the virtual switch hosting the team. Passive failover in the event one of the adapters in the team goes down.

Is it possible that there is a picure missing?
