Correct Answer: BE

Explanation: 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.

Correct Answer: B

Explanation: vSphere High Availability is the correct answer because it meets the requirements of making the virtual machine available quickly after a failure occurs and minimizing administrative effort. vSphere HA monitors the health and availability of the hosts and virtual machines in a cluster and automatically restarts any failed virtual machines on other hosts within minutes. vSphere HA also supports proactive HA, which can migrate virtual machines from hosts that are about to fail or have degraded performance. vSphere HA is easy to configure and manage, as it only requires enabling HA on the cluster level and setting some basic policies and options. Distributed Services Engine,Fault Tolerance, and vSphere Distributed Resource Scheduler are not valid or optimal solutions for this scenario. Distributed Services Engine is a new feature in vSphere 7 that provides network services such as firewalling, load balancing, routing, and NAT for virtual machines and containers. It does not directly affect the availability or recovery of virtual machines after a failure. Fault Tolerance provides continuous availability for virtual machines by creating a secondary copy of the virtual machine that runs in lockstep with the primary copy on another host. If the primary copy fails, the secondary copy takes over without any interruption or data loss. However, Fault Tolerance has some limitations and overheads, such as requiring dedicated network bandwidth, supporting only one vCPU per virtual machine, and consuming twice as much CPU and memory resources as a single virtual machine. Fault Tolerance also requires more administrative effort than vSphere HA, as it needs to be enabled and configured for each individual virtual machine. vSphere Distributed Resource Scheduler is a feature that balances the workload and resources across a cluster by automatically migrating virtual machines based on their demand and priority. It does not directly affect the availability or recovery of virtual machines after a failure, although it can work together with vSphere HA to find optimal hosts for restarting failed virtual machines.

Correct Answer: B

Explanation: The host rebuild reserve is a feature that allows vSAN to reserve space in the cluster for vSAN to be able to repair in case of a single host failure. This reservation is set to one host worth of capacity, which means that if one host in the vSAN cluster fails and no longer contributes storage, there is still sufficient capacity remaining in the cluster to rebuild and re-protect all vSAN objects. This feature prevents the creation of new VMs or powering on VMs if such operations consume the reserved space. By default, the host rebuild reserve is disabled, but it can be enabled in the vSAN Services configuration. The other options are not related to the hostrebuild reserve.
