vSAN will use a 4+1 RAID-5 data placement scheme with parity will be used is the correct answer because vSAN 8 ESA uses adaptive RAID-5 erasure coding that depends on the number of hosts in the cluster. If the cluster has 6 or more hosts, vSAN will use a 4+1 RAID-5 scheme, where the data is written as a stripe of 4 data bits and 1 parity bit across 5 hosts. This provides a failure tolerance of 1 (FTT=1) and a space efficiency of 1.25x. If the cluster has less than 6 hosts (3 to 5), vSAN will use a 2+1 RAID-5 scheme, where the data is written as a stripe of 2 data bits and 1 parity bit across 3 hosts. This also provides a failure tolerance of 1 (FTT=1) but a space efficiency of 1.5x. In this case, the cluster has 5 hosts, so vSAN will use the 4+1 RAID-5 scheme.

The other options are incorrect for the following reasons:

• A, vSAN will use a 2+1 RAID-5 data placement scheme with parity will be used, is incorrect because vSAN will only use this scheme if the cluster has less than 6 hosts but more than 2 hosts. In this case, the cluster has 5 hosts, so vSAN will use the 4+1 RAID-5 scheme.
• B, RAID 5 will provide an FTT=2 level of protection in this case, is incorrect because RAID 5 can only provide an FTT=1 level of protection, regardless of the number of hosts or the data placement scheme. To achieve an FTT=2 level of protection, vSAN would need to use RAID 6 erasure coding, which requires at least 6 hosts in the cluster.
• D, vSAN will spread the components across all of the disk groups, is incorrect because vSAN will not necessarily spread the components across all of the disk groups in the cluster. vSAN will only spread the components across as many disk groups as needed to meet the storage policy requirements and to balance the load and capacity. In this case, vSAN will only need to spread the components across 5 disk groups for each stripe of RAID-5 data. References:

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:

To monitor the performance of vSAN File Services, the vSAN administrator must enable both the vSAN File Services and the vSAN Performance Service. The vSAN File Services provides SMB file shares to host clients, while the vSAN Performance Service collects and analyzes performance statistics and displays them in the vSphere Client. The other services are not related to vSAN File Services performance monitoring.

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:

To add 30 additional vSAN ReadyNodes to an existing vSAN cluster with the fastest approach, the vSAN administrator should use a Host Profile that was extracted from an existing host. AHost Profile is a configuration template that captures the settings of a reference host and applies them to other hosts or clusters. This way, the administrator can quickly and consistently configure multiple hosts with the same settings, such as network, storage, security, and services. The other options are not correct. Running vim-cmd to capture and apply the configuration from an existing host is not as fast or convenient as using a Host Profile, as it requires running commands on each host individually. Launching Quickstart to Add Hosts to a vSAN Cluster is not possible, as Quickstart is only available for new clusters or clusters that were configured through Quickstart. Cloning the ESXi boot partition to all new hosts is not recommended, as it might cause conflicts or errors with the host identity, network settings, or licenses.
