VCP-VVF Practice Test 29 — 15 Questions

Question 1

An administrator is designing a vSphere Foundation 9 environment with a vSAN datastore. The administrator needs to ensure that virtual machines remain available even if a single disk or disk group fails. Which vSAN storage policy setting should be configured?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Number of failures to tolerate = 1. The 'Number of failures to tolerate' policy setting is the primary mechanism in vSAN for defining redundancy. Setting it to 1 instructs vSAN to maintain at least one additional copy of the data so that a single disk or disk group failure does not cause data loss or unavailability. The other settings address performance, capacity reservation, or provisioning behavior, but none provide the required fault tolerance.

Answer

Number of disk stripes per object = 2

Answer

Force provisioning = Yes

Answer

Object space reservation = 100%

Question 2

An administrator is deploying a new three-node vSphere Foundation cluster. The design requires that virtual machine files be placed on a datastore that supports the vSphere Virtual Volumes (vVols) framework so that per-VM storage policies can be enforced at a granular level. The storage array has already been registered as a VASA provider and presents a protocol endpoint. Which action must the administrator take next so that the vVols datastore becomes visible and usable in the vSphere Client?

Accepted Answer

Rescan the storage adapter on each host and mount the storage container that the array exposes as a vVols datastore.. Once the VASA provider is registered and the protocol endpoint is presented, the array advertises storage containers that ESXi hosts discover during a storage rescan. Mounting a discovered container produces the vVols datastore that appears in the vSphere Client and supports granular per-VM storage policies. No VMFS formatting or NFS client configuration is involved, because the container itself is the datastore backing.

Answer

Add the protocol endpoint to a new datastore cluster and enable Storage DRS so the container is created automatically.

Answer

Create a VMFS datastore on the protocol endpoint LUN and enable the vVols attribute on it.

Answer

Configure the NFS client on each host to mount the storage container using the array management IP address.

Question 3

An administrator is deploying vSphere Foundation 9.0 and wants to understand how vSphere Distributed Services Engine (DPU-based infrastructure offloading) changes the host architecture before ordering hardware. Which statement correctly describes the role of a data processing unit in this environment?

Accepted Answer

The DPU provides a separate ARM-based compute domain that runs infrastructure services offloaded from the x86 host, while ESXi remains the hypervisor on the server.. vSphere Distributed Services Engine moves infrastructure services onto a DPU that has its own ARM-based compute domain, while ESXi remains the hypervisor running on the x86 server CPUs. This split allows networking, storage, and security functions to be offloaded, freeing server cores for virtual machines. The DPU is integrated in the host rather than hosting the hypervisor or acting as a simple passthrough accelerator.

Answer

The DPU must be installed in a separate management cluster and communicates with ESXi hosts only over a dedicated Fibre Channel fabric.

Answer

The DPU replaces the hypervisor kernel, and ESXi runs entirely inside a virtual machine hosted on the DPU's ARM cores.

Answer

The DPU acts only as a passthrough PCIe device that accelerates encryption but cannot run any independent software services.

Question 4

An administrator is troubleshooting a performance issue on a vSphere 9.0 cluster. A virtual machine running a latency-sensitive database is experiencing high CPU ready time. The administrator runs esxtop and observes that the %RDY value for the VM is consistently above 10%. Which action should the administrator take FIRST to reduce CPU ready time for this VM?

Accepted Answer

Reduce the number of vCPUs assigned to the virtual machine.. High CPU ready time (%RDY) indicates the VM is waiting for physical CPU resources. A common cause is over-provisioning vCPUs, which increases co-scheduling constraints. Reducing the vCPU count makes it easier for the hypervisor to find available cores, directly lowering ready time. Adding vCPUs or pinning to cores can worsen the problem. Increasing shares only helps under contention and does not address over-sized vCPU allocation.

Answer

Increase the CPU share value for the virtual machine.

Answer

Enable CPU affinity for the virtual machine to pin it to specific physical cores.

Answer

Increase the number of vCPUs assigned to the virtual machine.

Question 5

An administrator is deploying a new vSphere Foundation 9 environment and needs to provide centralized, policy-based storage management for a mixed workload of block and file datastores. Which vSphere Foundation component should be used to create and assign storage policies that abstract the underlying datastore capabilities?

Accepted Answer

vSphere Storage Policy Based Management (SPBM). vSphere Storage Policy Based Management is the correct choice because it is the centralized framework within vSphere Foundation that abstracts storage capabilities and enforces policies across block and file datastores. It allows administrators to define requirements such as encryption, replication, and performance, and then assign those policies to virtual machines, ensuring consistent management regardless of the underlying storage technology.

Answer

NFS 4.1 datastore

Answer

VMFS6 datastore

Answer

vSphere Virtual Volumes (vVols)

Question 6

An administrator is configuring a vSphere Standard Switch on a new ESXi host. The physical uplink connects to a switch port that carries VLAN 10 (management) and VLAN 20 (virtual machine traffic) as tagged 802.1Q frames. Virtual machines must send their traffic untagged on VLAN 20. Which virtual switch port group configuration should the administrator use for the virtual machine network?

Accepted Answer

Set the port group VLAN ID to 20. When a physical uplink carries multiple tagged VLANs, each virtual machine port group is assigned the specific VLAN ID it should use. Setting the port group VLAN ID to 20 lets the standard switch tag outbound frames and untag inbound frames, so guests can send ordinary untagged traffic. VLAN 4095 enables guest tagging, VLAN 0 uses the native VLAN, and the default value is 0, none of which satisfy the requirement.

Answer

Set the port group VLAN ID to 4095

Answer

Leave the port group VLAN ID at its default value

Answer

Set the port group VLAN ID to 0

Question 7

An administrator is setting up vSphere Lifecycle Manager (vLCM) in a vSphere Foundation 9.0 environment to manage ESXi host images. The administrator wants to ensure that all hosts in a cluster are compliant with a specific firmware version for their network adapters. Which component must be included in the vLCM image to manage firmware?

Accepted Answer

A hardware support manager (HSM) added as a plugin to vLCM.. To manage firmware with vSphere Lifecycle Manager, a hardware support manager (HSM) must be added as a plugin. The HSM integrates with vLCM to provide firmware updates for hardware components like network adapters. Without an HSM, vLCM can only manage ESXi base images and add-ons, not firmware. Therefore, the administrator must include an HSM in the vLCM configuration to ensure firmware compliance.

Answer

A vendor-specific ISO image uploaded to the vLCM depot.

Answer

A base image that includes the latest ESXi version.

Answer

An add-on component that contains the firmware payload.

Question 8

An administrator is troubleshooting intermittent VM disconnects in a vSphere 9.0 environment. The environment uses a vSphere Distributed Switch with 24 uplinks across two leaf-spine fabric switches. The administrator suspects a physical switch port is flapping. Which ESXi command should the administrator run to verify the current link state and detect any physical NIC down events on the host?

Accepted Answer

esxcli network nic get -n vmnic0. The correct command is esxcli network nic get -n vmnic0, which provides detailed link status for a specific physical NIC. It shows whether the link is up or down, speed, duplex, and other counters. This directly addresses the need to verify link state and detect flapping on an ESXi 9.0 host.

Answer

esxcli network ip interface ipv4 get

Answer

esxcli network vswitch dvs vmware list

Answer

esxcli network firewall ruleset list

Question 9

An administrator is troubleshooting a vSphere 9.0 cluster where a virtual machine experiences periodic brief network outages. The VM has a single VMXNET3 adapter connected to a standard vSwitch with two physical uplinks in an active/standby team. Investigation shows that when the active uplink fails, the standby takes over, but the VM's MAC address table on the physical switch does not update immediately. Which vSphere feature should the administrator enable to reduce the failover time and avoid MAC address table update delays?

Accepted Answer

Notify Switches. Enabling Notify Switches makes ESXi send a RARP packet when a vNIC moves to a different uplink, which updates the physical switch's MAC address table. This avoids the delay where the switch still forwards frames to the failed uplink, causing packet loss. The other options either detect failures or manage load but do not directly trigger the MAC table update needed for fast convergence.

Answer

Beacon probing

Answer

Failback

Answer

Route based on physical NIC load

Question 10

An administrator is managing a vSphere Foundation 9.0 environment with multiple ESXi hosts in a cluster. The administrator needs to ensure that when a host enters maintenance mode, all virtual machines are automatically migrated to other hosts using vSphere vMotion. Which cluster setting must be enabled to achieve this?

Accepted Answer

vSphere DRS is enabled and set to fully automated.. To automatically migrate VMs when a host enters maintenance mode, DRS must be enabled and set to fully automated. DRS uses vMotion to evacuate VMs to other hosts in the cluster. While vMotion must be configured, it is DRS that orchestrates the migrations. HA does not handle planned maintenance evacuations.

Answer

vSphere vMotion is enabled on all VMkernel adapters.

Answer

vSphere HA is enabled with host monitoring.

Answer

vSphere DRS is enabled but set to partially automated.

Question 11

An administrator must guarantee that a business-critical virtual machine always has physical memory reserved so it is never reclaimed by the balloon driver or swapped to a datastore, regardless of host memory pressure. Which vSphere setting should be configured?

Accepted Answer

Set the virtual machine's memory reservation equal to its configured memory size. A memory reservation of the full configured size locks physical host memory to the virtual machine, preventing the VMkernel from reclaiming those pages via ballooning or swapping. Shares only affect contention priority, and limits and swap-file placement change behavior without guaranteeing memory. The reservation is the mechanism that provides the hard protection the scenario demands.

Answer

Configure a memory limit equal to the virtual machine's configured memory size

Answer

Set the virtual machine swap file location to a high-performance datastore and disable page sharing

Answer

Enable memory compression on the host and set a high memory shares value for the virtual machine

Question 12

An IT architect is designing a new vSphere Foundation 9.0 environment that must support a 25 GbE storage network with end-to-end lossless Ethernet for iSCSI traffic. The physical switches are already configured for Priority Flow Control and Data Center Bridging. Which ESXi network construct should the architect design to meet this requirement?

Accepted Answer

A vSphere Distributed Switch with a dedicated VMkernel adapter and Data Center Bridging enabled for the iSCSI traffic class. Lossless Ethernet for iSCSI on ESXi requires the host to participate in Data Center Bridging so that Priority Flow Control can be negotiated with the upstream switches. Only the vSphere Distributed Switch exposes DCB configuration in vSphere Foundation 9.0, and pairing it with a dedicated VMkernel adapter keeps storage traffic isolated. Standard switches and NIOC-based prioritization cannot deliver the lossless guarantee the scenario demands.

Answer

A standard vSphere Standard Switch with a dedicated VMkernel adapter and jumbo frames enabled

Answer

A vSphere Distributed Switch with Network I/O Control version 3 enabled and shares set to High for the iSCSI VMkernel adapter

Answer

A vSphere Distributed Switch with a dedicated VMkernel adapter on a VLAN that has no teaming policy applied

Question 13

An administrator is configuring vSphere Foundation 9.0 to use vSphere Trust Authority (vTA) for securing ESXi hosts. The administrator has deployed the Trust Authority Cluster and configured the Trusted Cluster. After attesting the ESXi hosts, the administrator notices that some hosts are not compliant. Which action should the administrator take to ensure the hosts become compliant?

Accepted Answer

Verify that the hosts' TPM 2.0 is enabled and the attestation certificates are valid.. For vSphere Trust Authority, hosts must have TPM 2.0 enabled and valid attestation certificates. Non-compliance indicates attestation failure, often due to TPM misconfiguration or expired certificates. The administrator should verify these components to restore compliance. Other actions like restarting services or reinstalling ESXi do not address the root cause.

Answer

Add the hosts to a different cluster with vSphere HA enabled.

Answer

Reinstall ESXi on the non-compliant hosts.

Answer

Restart the Trust Authority Agent service on the non-compliant hosts.

Question 14

An administrator is designing a vSphere Foundation 9 environment with a vSAN datastore. The administrator needs to ensure that virtual machines remain available even if a single disk or disk group fails. Which vSAN storage policy setting should be configured?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

A standard key provider backed by an external Key Management Server (KMS). Encryption at rest with separation from host compromise requires keys to be held outside the host's direct control and access to be gated by attestation. A standard key provider backed by an external KMS keeps key material off the ESXi host, and vSphere Trust Authority adds an independently attested trust cluster that decides which hosts may retrieve keys. Together they meet both requirements, while Native Key Provider, vTPM, and encrypted vMotion address different problems.

Answer

Encrypted vMotion

Answer

vSphere Native Key Provider

Answer

vSphere Virtual TPM (vTPM) devices

Question 15

An administrator is configuring vSphere Distributed Switch (vDS) health check in a vSphere Foundation 9.0 environment. The administrator wants to verify that VLAN and MTU settings are consistent across all ESXi hosts participating in the vDS. Which health check should be enabled?

Accepted Answer

VLAN and MTU. The VLAN and MTU health check in vSphere Distributed Switch validates that VLAN and MTU configurations are consistent across all ESXi hosts in the switch. It checks physical NICs, VMkernel adapters, and virtual switches for mismatches. Enabling this health check ensures that network settings are uniform, preventing connectivity issues caused by configuration drift.

Answer

MTU Check

Answer

Team and Failover

Answer

Network Health
