A cluster experiences intermittent high CPU ready time on multiple VMs during business hours. The administrator wants to identify whether contention is coming from overcommitment or from a specific noisy neighbor VM. Which metric and view is most appropriate to start with in vSphere Client?

A vCenter Server is used to manage multiple clusters. The security team requires that different administrators can only see and manage VMs in their own departments, while still using the same vCenter Server. What is the recommended way to implement this requirement?

A VM is protected by vSphere HA. The administrator wants the VM to restart with a higher priority than other VMs after a host failure, and also wants to ensure the VM is restarted even if it is not responding (OS hang) without waiting for long timeouts. Which combination of features meets these requirements?

A team wants to allow developers to create and revert to known-good VM states during testing, but the storage team is concerned about uncontrolled growth and long snapshot chains. What is the best-practice guidance to provide?

An ESXi host has two physical uplinks connected to separate physical switches. The requirement is to maintain connectivity if a single uplink or switch fails, and also to avoid MAC flapping or loops when using upstream redundancy. Which configuration is most appropriate on a vSphere Distributed Switch?

A VMFS datastore is experiencing intermittent latency spikes. The array team confirms the underlying LUNs are healthy. The administrator suspects path thrashing due to an incorrect multipathing policy on ESXi. Which combination is most likely to cause periodic latency due to frequent path switching?

An administrator needs to ensure that only specific VLANs are permitted on a trunk port group used by virtual machines on a vDS. What is the most appropriate configuration to meet this requirement?

A storage array supports VAAI primitives. The administrator wants to offload storage-intensive operations to the array to reduce ESXi CPU usage and speed up provisioning. Which operation benefits directly from VAAI offload on supported block storage?

A cluster uses vSphere HA with admission control enabled. After adding several new VMs, the administrator cannot power on additional VMs even though current CPU and memory utilization are low. Which HA behavior most likely explains this condition?

A vSphere administrator needs to quickly identify which ESXi hosts have Secure Boot enabled across multiple clusters. Which vCenter Server feature should be used to view this host compliance state at scale?

A VM running a latency-sensitive database must be protected from ballooning and swapping during host memory contention. Which setting best addresses this requirement?

An administrator must provide L2 network isolation between tenant networks on the same distributed switch while using the same IP subnet and VLAN ID. Which vSphere feature is designed for this use case?

After a failed vCenter Server appliance reboot, the vSphere Client is unavailable, but ESXi hosts are reachable via direct Host Client access. The administrator needs to determine whether critical vCenter services are running. Which interface provides the most direct way to check and manage vCenter services?

A cluster uses vSphere DRS. A specific VM must always remain on a subset of hosts due to licensing restrictions, but it should still be eligible for vMotion within that subset. Which configuration meets the requirement?

A VM has multiple virtual disks. The administrator wants only one data disk to be excluded from snapshots because it is backed up by an in-guest agent and changes frequently. Which VM setting should be used?

An administrator is troubleshooting packet loss for a VM connected to a vSphere Distributed Switch. The physical switch configuration is suspected. Which vSphere feature can help validate VLAN and MTU consistency between the VDS and the upstream physical network?

A vSphere administrator plans to use vSphere HA with datastore heartbeating. The environment contains several datastores, but some are mounted only on a subset of hosts. What is the best practice to ensure reliable datastore heartbeating for HA across the cluster?

A storage administrator wants to prevent a single host from consuming an excessive number of IOPS on a shared VMFS datastore, impacting other hosts. Which capability directly addresses this requirement?

A security policy requires that ESXi hosts do not accept management connections unless they are explicitly from authorized administration systems. The environment uses a dedicated management network. Which approach best meets the requirement while aligning with vSphere best practices?

An administrator wants to ensure all ESXi hosts in a cluster use the same NTP configuration and SSH service policy. Which vSphere feature is the best fit for enforcing these settings at scale?

A virtual machine loses network connectivity after being migrated to another host. Other VMs on the destination host have normal connectivity. The VM is connected to a distributed port group. What is the most likely cause?

A VM must be prevented from consuming excessive CPU and impacting other workloads. Which setting provides a strict upper bound on CPU consumption for that VM?

A VM running a database requires the lowest possible latency. The administrator is considering VM settings changes. Which action is most aligned with low-latency best practices?

An administrator wants a cluster to automatically load balance VMs across hosts based on resource demand, but also wants maintenance operations to still function normally. Which feature should be enabled/configured?

A security team requires that VMs on a specific network segment be prevented from communicating with each other at Layer 2, while still allowing communication to upstream routers and services. Which vSphere networking policy best meets this requirement?

An administrator receives an alarm that a host has lost access to one storage path, but the datastore remains accessible. The environment uses multipathing for redundancy. What is the most appropriate interpretation?

An administrator needs to move a VM to another datastore with no downtime. The VM currently uses a thick-provisioned VMDK, and the target datastore supports thin provisioning. What can the administrator do to both migrate the VM and change the disk provisioning format during the move?

A cluster uses vSphere Distributed Switches and Network I/O Control (NIOC). During periods of congestion, vMotion traffic must be guaranteed bandwidth without starving management traffic. Which configuration best addresses this requirement?

An administrator wants to enforce that only VMs with a specific naming convention and placed in a particular folder can be powered on. Which feature should be used to implement this control within vCenter Server?
