VMware vSAN Specialist v2: 5V0-22.23

Correct Answer: D

Explanation: The minimum required number of hosts to provide data redundancy for a vSAN stretched cluster using dual-site mirroring and local protection with 1 failure - RAID-1 (Mirroring) is six hosts. This is because a vSAN stretched cluster requires at least three hosts per site, and each site must have enough hosts to tolerate one host failure. Therefore, the minimum configuration is three hosts per site, plus one witness host at a third site, for a total of six hosts. References: [VMware vSAN Specialist v2 EXAM 5V0- 22.23], page 14

Correct Answer: A

Explanation: The impact to any virtual machine that was running on the failed host using vSANPolicy1 is that each virtual machine will be restarted on another vSAN host using vSphere HA. This is because vSANPolicy1 has a Failures to Tolerate setting of 1 failure - RAID-5 (Erasure Coding), which means that each object has four components (three data and one parity) distributed across four hosts. If one host fails, the object can still be accessed with the remaining three components,and vSphere HA will restart the virtual machine on another host. vSAN will also try to rebuild the missing component on another host, if there is enough capacity and resources. The other options are incorrect because they either assume that the object is unavailable or that the recovery process is delayed or impossible.

Correct Answer: C

Explanation: To upgrade the vSAN environment from vSAN 7.0 U3 to vSAN 8.0 using vLCM in a non-internet connected environment, the administrator should configure the vSphere Lifecycle Manager to download updates from a local UMDS-shared repository. UMDS stands for Update Manager Download Service, which is a component of vSphere Lifecycle Manager that can be used to download patches and updates for ESXi hosts, virtual appliances, and VMware Tools from the VMware online depot and store them in a shared repository. The administrator can then configure the vSphere Lifecycle Manager to use the UMDS-shared repository as a custom depot for patching and upgrading the vSAN cluster. This option allows the administrator to perform offline upgrades without requiring internet access for the vSAN cluster12 References: 1: VMware vSphere Lifecycle Manager Administration, page 22 2: VMware vSphere Update Manager Download Service, page 5
