A vSAN administrator needs to enable vSAN ESA.
Which two requirements need to be met? (Choose two.)
Correct Answer:
BE
To enable vSAN ESA, two requirements that need to be met are: vSAN Standard license or higher, and vSAN ReadyNodes configuration. vSAN Standard license or higher is required to use vSAN ESA, as it is a feature that is only available in vSAN 8.0 or later versions. vSAN ESA is an optional, alternative architecture to vSAN OSA that is designed to process and store data with higher efficiency, scalability, and performance. vSAN ReadyNodes configuration is required to use vSAN ESA, as it is a hardware configuration that is pre-configured, tested, and certified for VMware Hyper-Converged Infrastructure Software. Each vSAN ReadyNode is optimally configured for vSAN ESA with the required amount of CPU, memory, network, and storage NVMe devices. The other options are not correct. vSAN Build Your Own configuration is not supported for vSAN ESA, as it might not meet the hardware requirements or compatibility for vSAN ESA. vSAN Witness Appliance is not required to use vSAN ESA, as it is only needed for stretched cluster or two-node cluster configurations.

An administrator is tasked to create a Kerberos secured NFS v4.1 file share.
Which information is minimally required during the configuration of the File Service?
Correct Answer:
B
To create a Kerberos secured NFS v4.1 file share, the administrator needs to provide the following information during the configuration of the File Service:
✑ Active Directory Domain: The domain name of the Active Directory server that provides Kerberos authentication service for the NFS server and clients. For example, example.com.
✑ User Account: The user name of the Active Directory account that has permissions to join the NFS server to the domain and create service principal names (SPNs) for the NFS server. For example, administrator@example.com.
✑ Password: The password of the Active Directory account that is used for authentication. For example, P@ssw0rd.
These information are required to enable Kerberos security for NFS 4.1 and allow the NFS server to obtain a Kerberos ticket from the Active Directory server. The administrator also needs to specify the NFS share name, path, and access permissions1 References: 1: VMware vSphere Storage Guide, page 118
Refer to the exhibit.
An administrator uses SSH to log into a vSAN ESA host and runs theesxcli vsan debug object overviewcommand.
The administrator notices the Healthy Components column, the last column, is reporting some components are not in a fully healthy state.
What could cause this behavior?
Correct Answer:
D
The most likely cause for some components to be not in a fully healthy state is that one host is in maintenance mode with the ensure accessibility option. This option creates temporary durability components on other hosts to maintain the required number of failures to tolerate (FTT) until the original components are restored or rebuilt. These durability components are not considered fully healthy because they do not have full redundancy and might not be compliant with the storage policy. The other options do not explain why some components are not fully healthy, as they do not affect the FTT or the compliance state of the objects.

A vSAN administrator was presented with 30 additional vSAN ReadyNodes to add to an existing vSAN cluster. There is only one administrator to complete this task.
What is the fastest approach?
Correct Answer:
D
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.

A six-node vSAN ESA cluster contains multiple virtual machines, and a vSAN storage policy with the rule "Failures to tolerate" set to "1 failure - RAID-5 (Erasure Coding)" is assigned. A vSAN administrator has changed the rule in the assigned policy to "2 failures - RAID-6 (Erasure Coding)".
What is the result of this change?
Correct Answer:
D
The updated policy is serially applied to the virtual machines is the correct answer because changing the rule in the assigned policy will trigger a policy compliance check and a resynchronization of the affected objects. The policy change will not be rejected, queued, or ignored, as it is a valid and supported operation. However, the policy change will not be applied in parallel, as that would cause too much network and disk traffic. Instead, the policy change will be applied one virtual machine at a time, starting with the most critical ones, until all virtual machines are compliant with the new policy. References:
