An ESXi host reports 'No datastores found' in the inventory after a storage maintenance window. Which action is the most appropriate first step to restore access to shared VMFS datastores?

A cluster is configured with vSphere HA. After a host failure, several VMs do not restart on remaining hosts even though those hosts are powered on. Which cluster setting is the most likely cause?

An administrator wants to apply consistent networking (port groups, uplinks, and policies) across multiple ESXi hosts and simplify ongoing changes. Which vSphere feature best meets this requirement?

A VM frequently experiences high disk latency, but only on one datastore. Other VMs on different datastores are unaffected. Which metric in vSphere is MOST directly useful to confirm the latency is storage-device related rather than guest OS CPU contention?

A support engineer needs to expand a VM's VMDK that is running low on space. The disk is not the boot disk and the application can tolerate an online disk expansion. What is the recommended approach?

A VMkernel adapter used for vMotion is configured on several hosts. vMotion attempts fail with timeouts only when migrating between hosts in different racks. The physical network team confirms routing between racks is allowed but MTU differs by segment. What is the MOST likely cause and best corrective action?

An administrator needs to add a new ESXi host to an existing vCenter Server inventory. Which action is required to complete the add-host workflow successfully?

A VM running on an ESXi host reports "No network connectivity." The port group is configured correctly and other VMs on the same port group have connectivity. Which is the most likely VM-specific cause?

An administrator wants to prevent accidental deletion of a critical VM but still allow operators to power it on/off. Which vSphere feature best meets this requirement?

After migrating a VM to a new datastore, the VM fails to power on with an error indicating the file is locked. What is the most appropriate first action?

A VM is running out of disk space on its system drive. The administrator expands the VMDK from vCenter Server, but the guest OS still shows the old capacity. What should the administrator do next?

Users report intermittent VM network drops in a cluster using vSphere Distributed Switches. The issue occurs only after failover between uplinks on a specific host. Which configuration is most likely to cause this behavior?

An administrator needs to ensure that vMotion traffic is isolated from virtual machine traffic on the same ESXi hosts. Which approach aligns with vSphere best practices?

A vSphere administrator wants to increase VM availability during an ESXi host failure, but the application cannot tolerate being restarted from scratch. Which vSphere feature best addresses this requirement?

After a storage array maintenance event, multiple datastores are visible to some ESXi hosts but not others. The affected hosts show no storage path errors, but the datastores are missing. What is the most appropriate next troubleshooting step?

An administrator enables EVC on a cluster after adding newer CPUs. Shortly after, a VM cannot vMotion into the cluster, and the compatibility check fails even though the VM is powered on and running. Which VM condition most commonly prevents vMotion due to CPU feature exposure?

An administrator needs a centralized interface to manage ESXi hosts, clusters, and VM lifecycle tasks. Which component provides this primary management plane?

A VM is running but users report that it cannot be cleanly rebooted from the vSphere Client and guest operations show as unavailable. Pings to the VM still work. What is the most likely cause?

An administrator creates a new VM and expects it to receive an IP address from DHCP, but the guest shows no network connectivity. The vNIC is connected and the correct port group is selected. Which additional check is MOST appropriate on the ESXi networking side?

After a host reboot, multiple VMs fail to power on with an error indicating the datastore is inaccessible. The datastore uses iSCSI. Which is the BEST initial troubleshooting action?

A VM experiences frequent short pauses. Performance charts show memory ballooning and swapping on the ESXi host. Which action is MOST likely to reduce the pauses?

An administrator needs to allow a helpdesk team to reset VM passwords using guest OS customization tools but must prevent them from deleting VMs. What is the BEST approach?

A vMotion attempt fails. The error indicates that the source and destination hosts cannot access the same VM files. The VM is on shared storage in the cluster. What is the MOST likely cause?

An administrator needs to move a VM to a new distributed port group but must preserve the current MAC address to avoid breaking an application license bound to it. What is the BEST method?

A host intermittently disconnects from vCenter. The management network is stable, and DNS and NTP are correct. Logs show repeated certificate validation errors when the host tries to reconnect. What is the BEST next step to restore stable management connectivity?

A VMFS datastore shows repeated path failovers and high latency during peak hours. The storage array and fabric are healthy. The ESXi hosts use multiple paths to the LUN. Which setting is MOST likely to improve performance consistency by balancing I/O more effectively across active paths (when supported)?

An administrator needs to verify that ESXi host management agents are healthy because the host intermittently shows as “Not responding” in vCenter Server. Which action is the most appropriate first step on the ESXi host?

A support engineer needs to confirm whether a VM is actually powered on from the ESXi host perspective after the vSphere Client shows a stale power state. Which command provides the most direct view of VM power state on an ESXi host?

A VM must be isolated from other VMs on the same VLAN but still allowed to communicate with its default gateway. Which vSphere networking feature best meets this requirement on a vSwitch/port group?

An administrator is planning a vCenter Server deployment for a small environment and wants to minimize administrative overhead while maintaining centralized management for multiple ESXi hosts. Which component provides the centralized inventory and management plane for ESXi hosts and VMs?

A VM cannot vMotion and fails with an error indicating the target host cannot access the VM’s files. Other VMs can vMotion successfully. Which is the most likely cause?

A VM shows high disk latency and the datastore performance charts indicate elevated read/write latency during peak hours. What is the best next step to determine whether the issue is within the guest OS or on the storage path/infrastructure?

An administrator needs to ensure that when a VM is powered off, it can be moved between resource pools without impacting other running workloads. Which statement best describes the impact of moving a powered-off VM between resource pools?

A cluster uses HA. After a host failure, some VMs fail to restart because there is not enough unreserved capacity. Which setting most directly controls the amount of capacity set aside to guarantee failover resources?

A VM experiences intermittent network connectivity. The physical switch team reports that the ESXi host uplink is configured as an 802.3ad LACP port-channel. The ESXi host is using a standard vSwitch with two uplinks and a port group set to "Route based on IP hash". Which design issue is most likely causing the intermittent connectivity?

A VM backup product reports failures due to "changed block tracking inconsistent" after a storage issue. The VM also has multiple snapshots. What is the best remediation approach to restore reliable CBT-based backups while minimizing risk?

An administrator needs to quickly confirm which vCenter Server feature enables centralized management of ESXi hosts and their inventory from a single interface. Which component provides this capability?

A support technician is asked to ensure a virtual machine can be restored to a known-good state after installing a driver update. What is the most appropriate action before making the change?

A VM is connected to the correct port group but cannot reach any network resources. Other VMs on the same port group work normally. Which is the MOST likely VM-level cause?

After a power outage, multiple VMs show as 'inaccessible' in vCenter Server, but the ESXi host is connected and running. Datastores appear mounted on the host. Which initial troubleshooting step is MOST appropriate?
