VCP-DCV vSphere Architecture, Products and Solutions Practice Test 5 — 15 Questions

Question 1

A company experiences frequent host failures. The cluster has 5 hosts with 128 GB RAM each. The VMs have vCPU and memory reservations ranging from 1 GHz/512 MB to 4 GHz/8 GB. The administrator needs to ensure that if one host fails, the remaining hosts can accommodate all VMs. Which admission control policy is recommended?

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

Accepted Answer

Use cluster resource percentage - reserve 20% CPU and memory.. Percentage-based admission control with 20% reserve (equivalent to 1 out of 5 hosts) provides headroom for a single host failure while minimizing wasted capacity. For mixed VM sizes, slot-based admission control (Option A) can be inefficient due to varying reservation sizes. Disabling admission control (Option C) risks resource shortages during a failure. Option D reserves 25%, which is more than necessary and wastes resources.

Answer

Define slot sizes based on the largest VM.

Answer

Disable admission control and rely on DRS.

Answer

Use cluster resource percentage - reserve 25% CPU and memory.

Question 2

An administrator creates a DRS rule to separate two VMs (VM1 and VM2) using a 'Should' rule (separate VMs). After the rule is created, VM1 is manually vMotioned to a host that already runs VM2. What is the expected behavior?

Accepted Answer

VM1 remains on the host and a compliance violation is logged.. A 'Should' rule in DRS is a soft rule, meaning it is not strictly enforced. If an administrator manually vMotion's VM1 to a host running VM2, DRS will not automatically migrate it away; instead, it will log a compliance violation. The VM remains on the host, and the violation is recorded for review.

Answer

DRS automatically migrates VM1 to a compliant host.

Answer

The target host is placed into maintenance mode.

Answer

VM1 is powered off to prevent performance issues.

Question 3

An administrator wants to replicate a critical VM to a remote site with a Recovery Point Objective (RPO) of 15 minutes. Which vSphere feature should be used?

Accepted Answer

vSphere Replication. vSphere Replication is the correct feature because it provides asynchronous replication of VMs to a remote site with an RPO as low as 15 minutes. It operates at the VM level and is included with vSphere, making it suitable for this requirement without additional licensing for SRM.

Answer

Storage vMotion

Answer

vSphere vMotion

Answer

Site Recovery Manager (SRM)

Question 4

Which switch type requires a separate vCenter Server to manage its configuration?

Accepted Answer

vSphere Distributed Switch. The vSphere Distributed Switch (VDS) requires a separate vCenter Server to manage its configuration because the VDS is a centralized virtual switch that spans multiple ESXi hosts, and its configuration is stored in the vCenter Server database rather than on individual hosts. Without vCenter, the VDS cannot be created, configured, or managed, as the ESXi hosts rely on vCenter to synchronize the distributed port group settings and network policies across the cluster.

Answer

Virtual Edge Gateway Switch

Answer

vSphere Standard Switch

Answer

vSphere Edge Switch

Question 5

An administrator needs to migrate a powered-on VM from one datastore to another without any downtime. Which vSphere feature should be used?

Accepted Answer

Storage vMotion. Storage vMotion migrates a powered-on VM's virtual disks from one datastore to another with zero downtime, keeping the VM running throughout the copy. It is the correct feature when the requirement is datastore-level migration of a live VM.

Answer

Storage DRS

Answer

vSphere Replication

Answer

vSphere vMotion

Question 6

Which TWO capabilities are exclusive to vSphere with Tanzu compared to standard vSphere clusters?

Accepted Answer

Tanzu Kubernetes Grid Service. Options B and C are correct. vSphere with Tanzu provides a native Kubernetes control plane and the Tanzu Kubernetes Grid Service for managing Kubernetes workloads, which are not available in standard vSphere clusters. A (DRS and HA) and D (vMotion) are general vSphere features, not exclusive to vSphere with Tanzu. E (vSAN storage policies) is a vSAN capability, not exclusive to vSphere with Tanzu.

Answer

DRS and HA

Answer

vMotion

Answer

vSAN storage policies

Question 7

An administrator configures DRS on a cluster with two hosts. The administrator wants to ensure that two critical VMs (VM1 and VM2) always run on separate hosts. Which rule type should the administrator create?

Accepted Answer

Separate Virtual Machines. The 'Separate Virtual Machines' rule (option A) is correct because it explicitly instructs DRS to place VM1 and VM2 on different ESXi hosts, ensuring host-level isolation for availability. This rule type enforces an anti-affinity constraint that DRS respects during initial placement and subsequent load-balancing migrations, preventing both VMs from running on the same host simultaneously.

Answer

Virtual Machines to Hosts (Should run)

Answer

Keep Virtual Machines Together

Answer

Virtual Machines to Hosts (Must not run)

Question 8

An administrator notices that a virtual machine on an NFS datastore is experiencing intermittent performance degradation. The ESXi hosts are connected to the NFS server via a 10 GbE network. The administrator uses esxtop and sees high average latency on the storage device, but the NFS server reports low latency. What is the most likely cause?

Accepted Answer

Network congestion is causing TCP retransmissions. The most likely cause is network congestion causing TCP retransmissions. When the ESXi host sees high average latency on the NFS datastore but the NFS server reports low latency, it indicates that the delay is occurring in the network path between the host and the server, not on the server itself. TCP retransmissions due to network congestion would cause the host to experience higher latency than the server, matching the symptoms.

Answer

Jumbo frames are enabled on the ESXi hosts but not on the NFS server

Answer

The NFS server is performing data deduplication on the datastore

Answer

The NFS datastore is mounted with read-only permissions

Question 9

An administrator is planning a storage upgrade for a vSphere cluster. The cluster currently uses VMware vSAN as the primary datastore. The administrator wants to add capacity to the vSAN datastore without adding additional hosts. Which action should the administrator take?

Accepted Answer

Add a new disk group on each host with additional capacity disks. Adding a new disk group on each host with additional capacity disks directly increases vSAN datastore capacity without requiring host replacement. This method allows you to add new capacity disks while preserving existing disk groups and data placement policies. Option A is incorrect because replacing existing disks with larger ones, while possible, typically requires data evacuation or is more disruptive, and it is not the recommended approach when disk slots are available. Option B is invalid because disk groups are per-host; combining disks across hosts is not supported. Option D does not increase vSAN capacity and introduces a different datastore type.

Answer

Replace existing disks in each host with larger capacity disks and claim them to the same disk group

Answer

Combine disks from different hosts into a single disk group

Answer

Add a new VMFS datastore and use Storage vMotion to move VMs

Question 10

Which two of the following are characteristics of the vSphere Enhanced vMotion Compatibility (EVC) feature? (Choose two.)

Accepted Answer

It allows vMotion between hosts of different CPU generations within the same cluster. Option B is correct because EVC's core purpose is to enable vMotion (and DRS) between ESXi hosts with different CPU generations by presenting a common, compatible CPU feature set within the same cluster. Option D is correct because EVC achieves this by masking (hiding) newer CPU features from VMs so that all hosts in the cluster expose a uniform baseline CPU feature set, allowing live migration across mixed hardware. Option A is incorrect because EVC is configured at the cluster level (via the cluster's EVC settings), not per individual host. Option C is incorrect because memory overcommit is a separate memory-management behavior controlled by host/VM memory settings and reservations, not a default effect of EVC. Option E is incorrect because EVC can typically be enabled on a cluster without powering off all VMs, provided the hosts are compatible; it does not require all VMs to be powered off.

Answer

It is configured at the host level

Answer

It enables memory overcommit by default

Answer

It requires all VMs to be powered off before enabling

Question 11

A financial services firm maintains a multi-site vSphere environment with independent vCenter Server systems in New York and London, each managing approximately 200 virtual machines. The company requires a disaster recovery solution that can orchestrate failover of an entire site with automated IP address changes and integrated testing capabilities. They also need centralized management and the ability to attach the recovery site's vCenter to the same vCenter Single Sign-On domain as the protected site. The current vCenter versions are 7.0 Update 3. Which solution best meets these requirements while adhering to VMware best practices?

Accepted Answer

Deploy vCenter Site Recovery (SRM) paired with vSphere Replication, and use Enhanced Linked Mode to connect the vCenter systems.. VMware Site Recovery Manager (SRM) with vSphere Replication provides orchestrated disaster recovery with automated IP address changes and integrated testing capabilities. Enhanced Linked Mode allows both vCenter Server systems to share the same vCenter Single Sign-On domain, meeting the centralized management requirement. This combination is the VMware best-practice solution for multi-site failover with independent vCenter Servers.

Answer

Implement a vSAN stretched cluster across both data centers and enable proactive HA policies.

Answer

Configure vCloud Availability for vCloud Director to replicate VMs between sites.

Answer

Use vCenter High Availability (VCHA) to protect the vCenter Server and rely on vSphere HA for VMs.

Question 12

A financial services company runs a vSphere 8 environment with three clusters managed by a single vCenter Server. The security team mandates that all management traffic, including vMotion and vSAN, be isolated on dedicated VLANs. An administrator must verify which VMkernel adapters are configured for vMotion on each ESXi host. Which vSphere component provides this information in the vSphere Client?

Accepted Answer

The VMkernel adapters tab under the Networking section of each ESXi host. The VMkernel adapters tab is the authoritative place to see which services each VMkernel port has enabled, including vMotion. It shows the VLAN, IP address, and enabled services, allowing the administrator to confirm that vMotion is isolated on the correct VLAN across all hosts.

Answer

The Physical adapters tab under the Networking section of each ESXi host

Answer

The Host Profiles configuration for each ESXi host

Answer

The vSphere Distributed Switch topology diagram in the vSphere Client

Question 13

A small business runs three ESXi hosts in a single vSphere cluster. The administrator wants centralized management, alarm-based monitoring, and a single inventory view without deploying additional appliances. Which vSphere component provides this functionality?

Accepted Answer

VMware vCenter Server. vCenter Server is the management plane of vSphere, providing a single inventory, alarms, roles, and cluster services. The ESXi host client manages one host only, the vSphere Client is just the UI, and vRealize Operations is an add-on analytics product. For centralized management of multiple hosts, vCenter Server is the required component.

Answer

VMware ESXi host client

Answer

VMware vRealize Operations Manager

Answer

VMware vSphere Client (HTML5)

Question 14

An administrator is planning a new vSphere deployment for a small branch office. The branch has only three ESXi hosts and no shared storage array. The administrator wants to aggregate the local disks from all three hosts into a single distributed datastore that provides policy-based, software-defined storage. Which vSphere solution should be used?

Accepted Answer

VMware vSAN. vSAN is the only listed solution that takes the local disks already present in the three ESXi hosts and presents them as one distributed, policy-driven datastore without requiring an external array or file server. The other choices either depend on external storage hardware or represent a retired product.

Answer

NFS datastore mounted from a Linux server

Answer

VMware vSphere Storage Appliance (VSA)

Answer

VMware Virtual Volumes (vVols)

Question 15

An administrator is planning a new vSphere deployment and wants to use a storage architecture that presents file-level storage over the network, supports VMware vStorage APIs for Array Integration (VAAI) primitives, and allows multiple ESXi hosts to access the same datastore concurrently. Which storage type best matches these requirements?

Accepted Answer

NFS 3.1 datastore. NFS is the file-level network storage protocol in vSphere. NFS 3.1 datastores support VAAI primitives and can be mounted by multiple ESXi hosts simultaneously, enabling shared storage for HA and vMotion. Fibre Channel and iSCSI are block-level, and vVols is an array-integration framework, so NFS best matches the requirements.

Answer

iSCSI software adapter LUN

Answer

VMFS on a Fibre Channel LUN

Answer

Virtual Volumes (vVols) on NFS
