In vSphere 7, which DRS mode allows administrators to receive migration recommendations without automatic execution?

Answer: Manual

Manual DRS mode generates migration recommendations that administrators must approve and execute manually.

Which vSphere 7 feature allows live migration of VMs between vCenter Server instances without shared storage?

Answer: Cross-vCenter vMotion

Cross-vCenter vMotion in vSphere 7 supports live migration of VMs across different vCenter Server instances, including without shared storage.

What is the purpose of Enhanced vMotion Compatibility (EVC) in a vSphere cluster?

Answer: Mask advanced CPU features to ensure vMotion compatibility across different CPU generations

EVC masks host CPU features to a common baseline so VMs can be vMotioned between hosts with different CPU generations.

In vSphere 7 vSAN, what is the 'Failures to Tolerate' (FTT) policy setting of 1 with RAID-1 mirroring?

Answer: Data is mirrored across 2 hosts, tolerating 1 host failure

FTT=1 with RAID-1 mirrors VM data across 2 hosts, so the cluster can tolerate the failure of 1 host without data loss.

Which vSphere 7 tool is used to assess host compliance against a desired configuration baseline?

Answer: vSphere Host Profiles

vSphere Host Profiles capture and enforce a reference host configuration, allowing compliance checks against all cluster hosts.

What is a vSphere 7 resource pool used for?

Answer: Partitioning CPU and memory resources among VMs in a hierarchy

Resource pools allow hierarchical partitioning of CPU and memory resources with shares, reservations, and limits among groups of VMs.

In vSphere 7, which technology enables persistent memory (PMem) to be used as a high-performance storage tier for VMs?

Answer: vSphere Persistent Memory (vPMem)

vSphere Persistent Memory (vPMem) exposes host NVDIMM/PMem hardware to VMs as either a vPMem disk or a vPMem datastore.
