VCP-VVF Vmware Vsphere Foundation Fundamentals — 15 Questions

Question 1

An administrator is managing a vSphere Foundation environment and needs to place an ESXi host into Maintenance Mode without powering off the virtual machines running on it. Which DRS setting must be configured to ensure these virtual machines are automatically migrated to other hosts in the cluster?

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

Accepted Answer

Fully Automated DRS. Enabling Automated DRS allows vCenter to automatically migrate virtual machines off a host when it enters Maintenance Mode.

Answer

Disabled DRS

Answer

Partially Automated DRS

Answer

Manual DRS

Question 2

An administrator needs to configure Enhanced vMotion Compatibility (EVC) on an existing vSphere cluster containing mixed generations of Intel Xeon processors. What is a strict prerequisite before enabling EVC on the cluster?

Accepted Answer

The cluster must contain no virtual machines powered on with a feature set higher than the baseline.. All powered-on virtual machines in the cluster must be compatible with the target EVC baseline, often requiring them to be powered off or migrated if their current CPU feature set exceeds the baseline.

Answer

All ESXi hosts in the cluster must be placed into Maintenance Mode simultaneously.

Answer

All running virtual machines must have CPU hot-add enabled.

Answer

All virtual machines in the cluster must be powered off.

Question 3

An administrator is configuring storage I/O control (SIOC) on a datastore shared by multiple clusters in a vSphere Foundation environment. During peak hours, a batch processing VM overwhelms the datastore with IOPS. Which SIOC configuration prevents this VM from starving other critical workloads?

Accepted Answer

Configure a hard IOPS limit on the specific virtual machine disks causing contention.. Setting an explicit IOPS limit or shares configuration per virtual disk in SIOC governs the maximum IOPS a VM can consume on the shared datastore.

Answer

Increase the datastore congestion threshold percentage from 30ms to 50ms.

Answer

Disable Storage DRS on the shared datastore cluster.

Answer

Assign a higher disk share value to the batch processing virtual machine.

Question 4

An administrator is troubleshooting a memory-constrained vSphere cluster. A virtual machine with a configured memory size of 32 GB has a balloon driver (vmmemctl) that is actively reclaiming 8 GB of guest memory. Which underlying condition explains why the memory balloon driver is active?

Accepted Answer

The ESXi host memory usage has crossed the active reclamation threshold, requiring memory reclamation.. Ballooning activates when host-level memory consumption exceeds the target free threshold, prompting the ESXi hypervisor to reclaim memory from VMs.

Answer

The guest operating system has experienced a hardware memory error on the physical DIMM.

Answer

The virtual machine has exceeded its configured memory reservation limit.

Answer

The virtual machine has a memory limit set lower than its active working set.

Question 5

A vSphere administrator notices that a high-priority virtual machine is experiencing CPU contention on an eight-socket ESXi host. The virtual machine is configured with 16 vCPUs and the host has physical NUMA nodes containing 8 cores each. Which configuration step will best mitigate performance degradation caused by remote memory accesses?

Accepted Answer

Resize the virtual machine to 8 vCPUs to match the physical NUMA node size.. Aligning the vCPU count of a virtual machine to fit within a single physical NUMA node (or multiples thereof) prevents wide NUMA spanning and reduces remote memory latency.

Answer

Configure CPU shares to High for the affected virtual machine.

Answer

Increase the reservation on the virtual machine's memory settings to maximum.

Answer

Enable hyperthreading globally on the ESXi host cluster.

Question 6

A cluster in a vSphere Foundation environment has High Availability (HA) enabled. An ESXi host suffers a sudden kernel panic and disconnects from the management network, but its virtual machines continue running because the heartbeat datastores are still reachable. How does vSphere HA respond to this isolated host state?

Accepted Answer

HA executes the configured isolation response, such as powering off or shutting down VMs on that host.. When an ESXi host loses management network connectivity but can still heartbeat to storage, HA classifies it as isolated and executes the configured isolation response.

Answer

HA ignores the state change until management network connectivity is fully restored.

Answer

HA immediately powers off all VMs on the isolated host and restarts them on surviving hosts.

Answer

HA migrates all running VMs using vMotion to healthy hosts in the cluster.

Question 7

An administrator wants to deploy a new virtual machine from an OVF template stored on a local workstation using the vSphere Client. Which inventory object should the administrator right-click to initiate this deployment wizard?

Accepted Answer

Cluster or ESXi host. To deploy a template or OVF/OVA, the administrator right-clicks a cluster, host, or resource pool and selects 'Deploy OVF Template'.

Answer

Data center

Answer

vCenter Server root object

Answer

Virtual machine folder

Question 8

An administrator needs to monitor the real-time resource utilization of a specific virtual machine in the vSphere Client. Which tab in the vSphere Client should the administrator select to view live CPU and memory performance charts?

Accepted Answer

Monitor tab. The Monitor tab within a virtual machine's object view provides real-time and historical performance charts for CPU, memory, network, and storage.

Answer

Configure tab

Answer

Permissions tab

Answer

Summary tab

Question 9

An administrator is setting up a new virtual machine and needs to attach a persistent raw disk device. Which disk provisioning type should the administrator select during the virtual machine creation wizard?

Accepted Answer

Raw Device Mapping (RDM). Raw Device Mapping (RDM) allows a virtual machine to directly access a storage volume (LUN) from the SAN.

Answer

Thick Provision Lazy Zeroed

Answer

Thin Provision

Answer

Thick Provision Eager Zeroed

Question 10

An administrator needs to take a snapshot of a critical database virtual machine before applying a patch. Which option should be selected to ensure that memory state is NOT included in the snapshot file?

Accepted Answer

Deselect 'Snapshot virtual machine memory'. Unchecking 'Snapshot virtual machine memory' creates a crash-consistent snapshot without capturing the running RAM state.

Answer

Power off the virtual machine prior to snapshotting

Answer

Enable quiescing on the virtual machine settings

Answer

Select 'Disable Guest Customization'

Question 11

An administrator is managing a vSphere Foundation environment and needs to place an ESXi host into Maintenance Mode without powering off the virtual machines running on it. Which DRS setting must be configured to ensure these virtual machines are automatically migrated to other hosts in the cluster?

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

Accepted Answer

SDRS ensures that the destination datastore has sufficient available IOPS capacity to honor the 500 IOPS reservation.. SDRS respects SIOC reservations and limits when evaluating placement recommendations to ensure IOPS guarantees are not violated by moving a VM to a congested datastore.

Answer

SDRS suspends migration if any VMDK on the datastore has an active IOPS setting.

Answer

SDRS automatically converts the IOPS reservation into a storage capacity quota.

Answer

SDRS ignores SIOC reservations and solely relies on space utilization metrics for placement.

Question 12

An administrator is configuring a Resource Pool hierarchy in a vSphere Foundation cluster. A child resource pool is set to 'Expandable Reservation'. When does this setting take effect during resource contention?

Accepted Answer

When the child resource pool exhausts its own reservation and the parent has unreserved resources available.. Expandable Reservation allows a child resource pool to borrow unreserved resources from its parent resource pool when its own reservation is exhausted.

Answer

When the parent resource pool runs out of physical memory and triggers vSphere HA.

Answer

When virtual machines inside the child pool are powered off.

Answer

When Storage DRS initiates a datastore migration.

Question 13

A vSphere Foundation cluster has Proactive HA configured with a provider such as Dell OpenManage or HPE OneView. An ESXi host reports a degraded hardware status warning for a redundant power supply. How does Proactive HA respond to this event?

Accepted Answer

Proactive HA generates a recommendation or automatically migrates VMs off the degraded host based on the cluster automation setting.. Proactive HA evaluates vendor-supplied health sensors and acts according to the configured automation level, such as migrating VMs off the degraded host.

Answer

Proactive HA isolates the host from the management network using firewall rules.

Answer

Proactive HA immediately powers off the host to prevent electrical damage.

Answer

Proactive HA triggers vSphere HA to perform a hard restart of the host.

Question 14

An administrator is managing a vSphere cluster with strict licensing compliance rules. A specific virtual machine must be restricted to run on only two designated ESXi hosts out of a six-host cluster. Which construct should the administrator configure?

Accepted Answer

A VM-Host affinity rule specifying a Host Group containing the two designated hosts.. Virtual Machine-to-Host affinity rules (using 'Should run on' or 'Must run on' rules with datastores or host groups) restrict VM placement to specific hosts.

Answer

A storage DRS anti-affinity rule on the virtual machine disks.

Answer

A DRS resource pool share allocation set to restrict CPU scheduling.

Answer

An Enhanced vMotion Compatibility (EVC) baseline targeting those two hosts.

Question 15

An administrator wants to migrate a running virtual machine from one vCenter Server to another vCenter Server across different data centers without downtime. Which type of migration should be initiated in the vSphere Client?

Accepted Answer

Cross-vCenter vMotion. Cross-vCenter vMotion allows migrating running VMs between different vCenter instances.

Answer

Cold Migration

Answer

Storage vMotion

Answer

Standard vMotion
