An administrator has successfully deployed a vSAN Stretched Cluster and needs to ensure that any virtual machines that are created are placed in the appropriate site.
Which two steps are needed to complete this task? (Choose two.)
Correct Answer:
AE
To ensure that any virtual machines that are created are placed in the appropriate site, the administrator needs to create VM/Host groups for the two sites and create a storage policy that includes site affinity rules and apply to VMs. VM/Host groups allow the administrator to group virtual machines and hosts based on their location or preference. Site affinity rules specify which site a virtual machine should be placed on or prefer to run on. A single VM/Host group across both sites would not allow the administrator to control the placement of virtual machines. Putting the VMs in a vSphere DRS group or in the correct VM group would not affect their site affinity. References: 1, page 12; 2, section 3.2
What is 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)?
Correct Answer:
D
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
A vSAN administrator is planning to deploy a new vSAN cluster with these requirements:
Physical adapters share capacity among several traffic types Guaranteed bandwidth for vSAN during bandwidth contention Enhanced security
Which two actions should be taken to configure the new vSAN cluster to meet these requirements? (Choose two.)
Correct Answer:
CE
Utilizing Network I/O Control and isolating vSAN traffic in a VLAN are the two actions that should be taken to configure the new vSAN cluster to meet the requirements. Network I/O Control allows the vSAN administrator to create network resource poolsand assign bandwidth shares or reservations to different traffic types, such as vSAN, vMotion, or management. This ensures that vSAN traffic has guaranteed bandwidth during contention and can achieve better performance and availability. Isolating vSAN traffic in a VLAN enhances the security of the cluster by preventing unauthorized access or interference from other network segments. It also simplifies the network configuration and management by reducing the broadcast domain and avoiding IP address conflicts. Creating static routes between the vSAN hosts, using IOPS Limit rules in storage policies, and enabling jumbo frames are not necessary or recommended actions for this scenario. Static routes are not required for vSAN communication, as vSAN uses multicast or unicast depending on the version and configuration. IOPS Limit rules are used to limit the IOPS allocated to an object, which can degrade the performance and latency of the application. Jumbo frames can improve the network efficiency and throughput, but they are not mandatory for vSAN and require consistent configuration across all network devices. References:

A vSAN administrator has two identical VMware vSAN clusters, one for staging workloads and another for production workloads. Due to an unforeseen capacity requirement, the vSAN administrator is tasked with merging the staging vSAN cluster into the production.
Which three actions should the vSAN administrator perform on the staging cluster prior to moving the vSAN nodes to the production cluster? (Choose three.)
Correct Answer:
ABD
The three actions that the vSAN administrator should perform on the staging cluster prior to moving the vSAN nodes to the production cluster are:
✑ Disable vSAN Services: This will stop any vSAN-related operations on the staging cluster, such as resynchronization, rebalancing, or repair. This will also prevent any new virtual machines from being created or migrated to the staging cluster.
✑ Delete all Disk Groups: This will remove all disks from the vSAN cluster and erase all data on them. This will also free up the disks for use in the production cluster.
✑ Delete all partitions from the capacity disks: This will ensure that there are no remnants of any previous vSAN configuration on the disks. This will also avoid any potential conflicts or errors when adding the disks to the production cluster.
Enabling File Services, marking the disks for partial reservation, and removing all capacity drives are not necessary or recommended actions for this scenario. Enabling File Services would add an unnecessary layer of complexity and overhead to the staging cluster. Marking the disks for partial reservation would reduce the available capacity for vSAN and potentially cause performance issues. Removing all capacity drives would leave only cache disks in the staging cluster, which would not be compatible with vSAN. References:

An administrator wishes to prevent vCenter notifications of vSAN Health status during a scheduled maintenance window.
Which action can be taken to achieve this goal?
Correct Answer:
B
To prevent vCenter notifications of vSAN Health status during a scheduled maintenance window, the administrator can disable the alarm from the HTML client. This will suppress the alerts for a specified duration or until the alarm is re-enabled. Disabling the performance service, running performance diagnostics, or disabling SNMP service will not affect the vSAN Health status notifications.
