VCP-DCV vSphere Architecture, Products and Solutions Practice Test 3 — 15 Questions

Question 1

Refer to the exhibit. A vSphere administrator is reviewing a cluster configuration JSON. What can be determined from the configuration?

Accepted Answer

The cluster uses a slot-based admission control policy.. The 'ha_admission_control_policy' is set to 'fixedSlotPolicy', indicating slot-based admission control.

Answer

vSphere DRS is set to partially automated.

Answer

The cluster can tolerate two host failures.

Answer

The cluster has admission control disabled.

Question 2

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?

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 3

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.. With a 'Should' rule (separate VMs), DRS does not enforce the rule; it only logs a compliance violation if VMs run on the same host. Manual vMotion overrides DRS, so VM1 will remain on the host with VM2 and a violation is logged. Option A correctly describes this behavior. 'Must' rules would enforce separation, but 'Should' rules are advisory only.

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 4

What is the maximum number of ESXi hosts that can be managed by a single vCenter Server instance in vSphere 8 (standard domain)?

Accepted Answer

2000. 2000. In vSphere 8, a single vCenter Server instance can manage up to 2000 ESXi hosts in the standard domain. Option A (1000) is the limit for vCenter Server 7.x and earlier. Option B (500) is not the correct limit for any recent version. Option C (4000) is the limit for hosts in a linked mode group but not for a single instance.

Answer

1000

Answer

500

Answer

4000

Question 5

A vSAN cluster uses a storage policy with FTT=2 (RAID-6). Each object is 256 GB. What is the minimum usable capacity required to store 10 such objects, accounting for overhead?

Accepted Answer

6.4 TB. FTT=2 RAID-6 requires 3 copies (data + 2 parity). For 256 GB objects, total raw capacity per object = 768 GB. For 10 objects, raw = 7680 GB. With default overhead (~1.2x), usable is about 6.4 TB. Option A ignores overhead, B underestimates, D overestimates.

Answer

5.12 TB

Answer

2.56 TB

Answer

10.24 TB

Question 6

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 supports RPO as low as 5 minutes (depending on configuration). vMotion is for live migration, not replication. Storage vMotion is for storage migration. SRM uses replication but is a disaster recovery orchestration platform, not a replication engine itself.

Answer

Storage vMotion

Answer

vSphere vMotion

Answer

Site Recovery Manager (SRM)

Question 7

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 8

A company uses Linked Mode vCenter Servers across two data centers. One of the links fails. What happens to the management capabilities?

Accepted Answer

Each vCenter Server can manage its own inventory, but cross-datacenter tasks fail.. In a Linked Mode configuration, each vCenter Server operates independently but shares licensing, roles, and permissions across the group. When the link fails, each vCenter Server retains full management capability over its own inventory, but cross-datacenter operations—such as moving a VM between clusters managed by different vCenter Servers—fail because the inter-vCenter communication channel is unavailable.

Answer

Both vCenter Servers become unavailable.

Answer

One vCenter Server takes over management of both data centers.

Answer

vSphere HA on both clusters reactivates the link.

Question 9

An administrator wants to deploy a new ESXi host using vSphere Lifecycle Manager (vLCM). The host has a different hardware version than the cluster baseline. Which action is required?

Accepted Answer

Create a separate cluster with a compatible image specification for the new host.. vSphere Lifecycle Manager (vLCM) uses image-based management, where a single image specification defines the exact software and firmware versions for all hosts in a cluster. If a host has a different hardware version, it cannot accept the same image because the hardware compatibility requirements differ. Creating a separate cluster with a compatible image specification allows the host to be managed independently with its own lifecycle baseline.

Answer

Use a host profile to apply the configuration.

Answer

Replace the host hardware to match the baseline.

Answer

Manually install the same ESXi version on the host before adding to the cluster.

Question 10

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 allows live migration of VM files while the VM remains powered on. vMotion migrates compute. vSphere Replication is for DR. Storage DRS balances storage but does not directly migrate without downtime.

Answer

Storage DRS

Answer

vSphere Replication

Answer

vSphere vMotion

Question 11

Which TWO features are provided by vSphere vDS (Distributed Switch) but not by a standard switch?

Accepted Answer

LACP support. The correct answers are B and D. LACP support (B) and Network I/O Control (D) are features exclusive to vSphere Distributed Switches. MTU configuration (A) and VLAN support (C) are available on both standard and distributed switches. Port mirroring (NetFlow) (E) is also a vDS-only feature, but the question specifically asks for TWO features commonly cited in exam objectives; LACP and Network I/O Control are the primary ones.

Answer

MTU configuration

Answer

VLAN support

Answer

Port mirroring (NetFlow)

Question 12

Which THREE parameters are considered by vSphere DRS when generating initial placement recommendations for a new VM?

Accepted Answer

Host network utilization. Options B, C, and D are correct. When generating initial placement recommendations for a new VM, vSphere DRS considers host CPU load, host memory load, and host network utilization. Storage I/O latency (option A) is not considered by DRS but by Storage DRS. VM power state (option E) is not a parameter for placement.

Answer

Storage I/O latency

Answer

VM power state

Question 13

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 14

A company has a vSphere cluster with vSphere HA enabled. During a host failure, virtual machines on the failed host do not restart. The administrator checks the HA agent log and sees the error message: 'HA agent on host <hostname> has no master detected'. Which of the following is the most likely cause?

Accepted Answer

The management network is isolated and HA isolation response is not configured. The error 'HA agent on host <hostname> has no master detected' indicates that the host cannot communicate with the HA master. This is typically caused by management network isolation. If the isolation response is not configured, the host may not take corrective action (e.g., attempt to contact master via datastore heartbeats). Option A is incorrect because datastore heartbeats are a secondary mechanism for detecting isolation, not the primary cause of the error. Option C is incorrect because vCenter Server being stopped does not prevent HA agents from electing a master among themselves. Option D is incorrect because VDS uplink failure detection policy is related to network teaming and failover, not directly to HA agent communication.

Answer

Datastore heartbeats are failing on the failed host

Answer

vCenter Server service is stopped

Answer

The VDS uplink failure detection policy is set to 'Link Status only'

Question 15

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)
