VMware Certified Professional - Data Center Virtualization Practice Exam 2025: Latest Questions

An administrator wants to centrally manage multiple ESXi hosts and enable cluster features such as DRS and HA. Which component provides this functionality?

A VM must be prevented from being powered on unless it uses a specific port group. Which feature should the administrator use to enforce this requirement?

A virtual machine experiences high memory usage, and the administrator observes ballooning activity on the ESXi host. What does ballooning indicate?

An administrator needs to ensure that vMotion traffic is isolated from management traffic and uses a dedicated uplink. What is the recommended approach?

A VMFS datastore is nearing capacity. The administrator adds additional extents to the datastore instead of expanding an existing LUN. What is a key operational drawback of using multiple extents on a VMFS datastore?

An administrator wants to roll out a standardized set of ESXi settings (for example, NTP, syslog, and networking) to many hosts and keep them consistent over time. Which vSphere feature is best suited for this goal?

A VM requires access to a physical USB dongle attached to an ESXi host. The VM must keep access to the dongle even if the VM is migrated with vMotion. Which solution best meets the requirement?

After enabling HA on a cluster, some hosts show an HA configuration warning related to the management network. Which action most directly addresses HA's dependency for host heartbeating?

A vSphere administrator is troubleshooting intermittent iSCSI storage latency. The ESXi host has two VMkernel adapters configured for iSCSI on separate VLANs, but both VMkernel adapters are using the same active uplink on the vSwitch. What should the administrator change to properly support iSCSI multipathing best practices?

A VM was converted from a physical server and now has poor network performance. The VM is using an emulated NIC type. Which change most commonly improves performance and reduces CPU overhead?

An administrator needs to provide a help desk team the ability to power on/off and reset VMs in a specific folder, but must not allow reconfiguration (CPU/memory/disk) or host-level actions. What is the best approach?

A VM must use two 10Gb uplinks for redundancy. Management wants the VM traffic to fail over automatically if one physical NIC fails, without requiring any changes inside the guest OS. Which vSphere networking feature best meets this requirement?

An administrator needs to verify that a datastore is accessible on all ESXi hosts in a cluster and identify any hosts that have lost connectivity. Which view in the vSphere Client provides this information most directly?

A vCenter Server appliance becomes unreachable. DNS is resolving correctly and the ESXi host running the appliance is healthy. You can access the VCSA management interface, but the vSphere Client login fails because core vCenter services are not running. What is the most appropriate next step?

A cluster uses DRS in fully automated mode. A particular business-critical VM must remain on its current host during a scheduled application validation window, but DRS should continue to operate normally for other VMs. What should the administrator do?

A VM has an application that is sensitive to time drift. The environment uses NTP on ESXi hosts. What is the recommended best practice for time synchronization inside the VM?

An administrator enables Network I/O Control (NIOC) on a vSphere Distributed Switch to prevent vMotion traffic from impacting production VM traffic during peak periods. Which configuration best achieves this goal?

A VM is experiencing high storage latency. The datastore is shared and performance issues affect multiple VMs during backup windows. The storage array team confirms no array-side faults. Which vSphere feature can help prevent one VM from monopolizing shared datastore I/O and impacting others?

After replacing an ESXi host’s physical NICs, the host shows as connected in vCenter, but VMs on that host lose network connectivity on a vSphere Distributed Switch (vDS). Other hosts on the same vDS are unaffected. What is the most likely cause?

A company plans to use vSphere Lifecycle Manager (vLCM) image-based remediation for a cluster. They require standardized firmware and driver compliance alongside ESXi updates and want to detect deviations from the approved hardware baseline. Which capability should be included in the design to meet this requirement?

An administrator needs a distributed virtual switch configuration that remains available even if vCenter Server is temporarily unavailable. Which component provides this capability?

A VM running a database workload is experiencing CPU Ready time spikes during business hours. The VM's CPU usage is moderate, but it competes with many other VMs on the same host. Which configuration change is most likely to reduce CPU Ready for this VM without adding new hardware?

A vSphere administrator wants to prevent a VM from being powered on unless it is encrypted. Which vSphere feature is designed to enforce this requirement at the VM level?

After migrating a vCenter Server to a new IP address, several ESXi hosts show as disconnected in the vSphere Client. DNS has been updated and resolves correctly. What is the most likely cause?

A cluster contains a mix of ESXi hosts with different CPU generations. The administrator needs to enable vMotion compatibility while allowing newer CPUs to run modern instructions when possible. Which feature best meets this requirement?
