5V0-22.23 Exam Dumps : VMware vSAN Specialist v2

To deploy a new two-node vSAN cluster with a shared witness, the administrator must meet several requirements, one of which is that the ESXi hosts must have a minimum of 64 GBs of memory. This is because each host must have enough memory to run the VMs and also to support the vSAN metadata overhead. The other options are not requirements for a two-node vSAN cluster with a shared witness. The ESXi hosts do not need SSDs or NVMe for Virtual Flash File System, as they can use any supported storage devices for vSAN. The ESXi host’s controller cache and advanced features do not need to be disabled, as they can be used to improve performance and reliability. The ESXi host’s drives do not need to be configured in RAID 1, as vSAN uses its own software-defined RAID mechanism to provide Failures to Tolerate.

To upgrade multiple vSAN Witness nodes with vLCM (single image management) that are used for vSAN Stretched and two-node Clusters, the administrator can upgrade two witness node types: appliance witness node and nested witness node. An appliance witness node is a virtual ESXi host that runs on a physical ESXi host and contains the witness components of VM objects stored in the vSAN cluster. A nested witness node is a virtual ESXi host that runs on another virtual ESXi host and contains the witness components of VM objects stored in the vSAN cluster. Both types of witness nodes can be managed by vLCM as independent nodes since vSphere 7.0 Update 3, as long as they are version 7.0 Update 2 or later. The other options are not correct. A shared witness node is a witness node that serves multiple vSAN clusters, which is not supported by vLCM. A dedicated witness node is a witness node that serves only one vSAN cluster, which is not a specific type of witness node. A physical witness node is aphysical ESXi host that contains the witness components of VM objects stored in the vSAN cluster, which cannot be upgraded by vLCM.

To implement HCI mesh between two clusters on vSAN that are located in geographically separate sites, the vSAN administrator should consider the following requirements:

• Either Layer 2 or Layer 3 communications can be used. HCI mesh supports both Layer 2 and Layer 3 network configurations, as long as the network latency and bandwidth requirements are met3
• The configuration must meet the same latency and bandwidth requirement as local vSAN. HCI mesh requires a network latency of less than or equal to 5 ms RTT between any two hosts in the participating clusters, and a network bandwidth of at least 10 Gbps for the vSAN network vmkernel port3 References: 3: VMware vSAN Specialist v2 Exam Preparation Guide, page 15
