VCP-DCV Practice Test 22 — 15 Questions

Question 1

A company's vSphere environment consists of four ESXi hosts, each with two 10 GbE physical NICs. The administrator configures a VDS with two dvUplinks and uses load-balancing policy 'Route based on IP hash'. To use IP hash, what additional configuration is required on the physical switches?

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

Accepted Answer

Configure link aggregation (LACP or static EtherChannel) on the switch ports. IP hash requires link aggregation (either LACP or static EtherChannel) to be configured on the physical switch ports to ensure proper hashing and load balancing. Option A is incorrect because VLAN trunking is a separate configuration and not directly required for IP hash. Option B is incorrect because configuring LACP on the VDS uplink port groups is optional and not mandatory for IP hash; the necessary link aggregation must be done on the physical switches. Option D is incorrect because IGMP snooping is used for managing multicast traffic and is not related to IP hash load balancing.

Answer

Enable VLAN trunking on the switch ports

Answer

Configure LACP on the VDS uplink port groups

Answer

Enable IGMP snooping on the switch

Question 2

Which storage feature in vSphere allows a VM to be migrated from one datastore to another without any downtime?

Accepted Answer

Storage vMotion. Storage vMotion is the correct answer because it enables live migration of a virtual machine's virtual disk files from one datastore to another with zero downtime. It uses a mirrored copy mechanism where the source and destination datastores are synchronized before the VM is switched to the destination, ensuring continuous VM availability.

Answer

vMotion

Answer

Distributed Resource Scheduler (DRS)

Answer

Storage DRS

Question 3

An administrator is troubleshooting performance issues on a vSphere cluster. Which TWO metrics should be monitored to identify CPU ready time contention?

Accepted Answer

Co-Stop. CPU ready time contention occurs when a virtual machine is ready to execute instructions but the ESXi host's CPU scheduler cannot immediately allocate physical CPU cycles. The %RDY metric directly measures the percentage of time a VM is waiting to be scheduled on a physical CPU, while Co-Stop specifically tracks time lost when vCPUs in a single VM are forcibly co-scheduled and then descheduled due to contention on the same physical core. Both metrics are primary indicators of CPU scheduling pressure.

Answer

Disk Kernel Latency

Answer

Memory Swap In Rate

Answer

Network Packet Drop Rate

Question 4

Which THREE of the following are characteristics of vSAN stretched clusters?

Accepted Answer

Provides site-level fault tolerance. Stretched clusters require a witness host in a third location, provide site-level fault tolerance, and require two fault domains (one per site). RAID 5/6 is supported but not unique to stretched clusters; it is still a single vSAN cluster.

Answer

Supports RAID 5/6 erasure coding

Answer

Uses a dedicated vSAN cluster separate from the main datastores

Question 5

An organization is upgrading from vSphere 7.0 Update 3 to vSphere 8.0. The current environment uses legacy baselines for patching. They want to move to vLCM. What must the administrator do to enable vLCM for the existing clusters?

Accepted Answer

Remove all legacy baseline attachments from the cluster before enabling vLCM.. VLCM cannot be enabled on a cluster that has legacy baseline attachments; all baseline attachments must be removed first. Option A is incorrect because while vCenter must be upgraded to vSphere 8, ESXi hosts can be upgraded after enabling vLCM. Option B is unnecessary; existing clusters can be used once baselines are removed. Option D is incorrect because vLCM is not backward compatible with legacy baselines.

Answer

Upgrade all ESXi hosts to vSphere 8 before enabling vLCM.

Answer

Create a new cluster and migrate hosts to it.

Answer

Enable vLCM on the cluster directly; it is backward compatible.

Question 6

An administrator manages a vSAN cluster with 5 ESXi hosts in a single failure domain. The cluster uses vSAN version 8 and is configured with a single disk group per host. A storage policy is applied to a group of VMs with 'Number of failures to tolerate = 1' and 'Primary level of failures = Host'. One host experiences a catastrophic hardware failure and is now marked as 'Absent' in the vSAN cluster. The administrator checks the vSAN health and finds that the affected host's disk group is completely lost. One of the VMs from that group previously had two replicas on different hosts and a witness component on a third host. The VM is still powered on, and the administrator sees that one replica was on the failed host. The other replica and witness are on surviving hosts. What is the current state of this VM regarding data accessibility?

Accepted Answer

The VM is fully accessible because it still has one replica and the witness.. With FTT=1 and primary level of failures = Host, the VM's object has 2 replicas and 1 witness. The surviving replica and witness are sufficient to maintain full read/write access. vSAN can rebuild the lost replica on another host, but even before rebuild, the VM remains fully accessible because there is still a complete replica. Option D correctly states this. Option A is incorrect because performance does not degrade; the VM uses the surviving replica. Option B is incorrect because the VM is accessible and can be rebuilt. Option C is incorrect because the witness is metadata; the VM has a full replica for reads.

Answer

The VM is accessible but performance is degraded because the disk group on the failed host is gone.

Answer

The VM is inaccessible because the lost replica cannot be rebuilt without a replacement host.

Answer

The VM is inaccessible because the witness component is now the only copy and cannot be used for reads.

Question 7

An administrator is configuring a vSphere Standard Switch. Which two settings are essential for basic network connectivity of virtual machines?

Accepted Answer

Port group name. For basic network connectivity of virtual machines on a vSphere Standard Switch, a port group must be created. Two essential settings are the port group name (to identify the network) and a VLAN ID (to associate the VMs with the correct VLAN; VLAN 0 is the default untagged VLAN). Without a name, the port group cannot be created; without a VLAN ID, VMs may not be properly segmented or may lack network access. Other options like MTU, network adapter type, and security policy are not essential for basic connectivity.

Answer

MTU

Answer

Network adapter type (e.g., E1000)

Answer

Security policy

Question 8

Place the steps to create a new standard virtual switch in vSphere in order.

Accepted Answer

Select a host, then access networking, then click Add Networking, then choose the connection type, then create and configure the new standard switch.. The correct sequence for creating a new standard virtual switch in vSphere is: select a host, access its networking settings, click Add Networking, choose the connection type (e.g., Virtual Machine), and finally create and configure the new standard switch. This order ensures you follow the wizard's logical steps and avoid errors.

Answer

Select a host, then click Add Networking, then access networking, then choose the connection type, then create and configure the new standard switch.

Answer

Access networking, then select a host, then click Add Networking, then choose the connection type, then create and configure the new standard switch.

Answer

Select a host, then access networking, then choose the connection type, then click Add Networking, then create and configure the new standard switch.

Question 9

Refer to the exhibit. An administrator runs the vmkfstools command on a VMFS datastore. Which information can be derived from the output?

Accepted Answer

The datastore ID is the file system UUID.. The output shows the file system UUID directly.

Answer

The datastore is formatted with VMFS version 6.82.

Answer

The datastore supports ESXi 6.5 and later.

Answer

The datastore has 1 TB capacity.

Question 10

An administrator is designing a new vSphere cluster for a mission-critical application that requires extremely low network latency between VMs within the same cluster. The cluster will use vSphere vMotion for maintenance. Which network configuration best meets these requirements?

Accepted Answer

Configure a distributed switch with jumbo frames and a dedicated VLAN for VM traffic.. A distributed switch with jumbo frames (MTU 9000) reduces CPU overhead and improves throughput for latency-sensitive VM traffic, while a dedicated VLAN isolates VM traffic from management and vMotion, minimizing contention. Jumbo frames allow larger payloads per packet, reducing the number of packets and interrupt processing, which is critical for low-latency applications. The distributed switch also provides consistent network policy across hosts, essential for vMotion compatibility.

Answer

Create separate standard switches for VM traffic and management.

Answer

Enable SR-IOV on the physical NICs and assign virtual functions to VMs.

Answer

Use a single vSphere Standard Switch for all traffic.

Question 11

An administrator is troubleshooting SSH connectivity to an ESXi host from a management workstation at 10.10.10.2. The SSH session is established, but the administrator cannot ping the host's IP 10.10.10.1. Based on the exhibit, what is the most likely cause?

Accepted Answer

ICMP traffic is blocked by the ESXi firewall.. The administrator can establish an SSH session, which proves that the ESXi host's SSH service is running and that TCP port 22 is reachable from the management workstation. However, the inability to ping the host's IP address (10.10.10.1) indicates that ICMP echo requests are being blocked. By default, the ESXi firewall blocks ICMP traffic, so the most likely cause is that ICMP is filtered by the host firewall.

Answer

The default gateway is not set correctly.

Answer

The SSH service is not running on the host.

Answer

The management workstation is on a different VLAN.

Question 12

Which TWO statements are true regarding vSphere Lifecycle Manager (vLCM) clusters? (Choose two.)

Accepted Answer

vLCM can manage vSAN clusters using a single image.. VLCM can manage vSAN clusters using a single image, which ensures that all hosts in the cluster run the same software version and driver/firmware combinations, including vSAN-specific components. This simplifies lifecycle management by eliminating the need for separate baselines and reduces compatibility issues.

Answer

vLCM only supports clusters with identical hardware.

Answer

vLCM can only remediate hosts that are part of a cluster.

Answer

vLCM requires vCenter Server to be in Enhanced Linked Mode.

Question 13

Which TWO conditions must be met to successfully enable vSphere Network I/O Control (NIOC) on a vSphere Distributed Switch? (Choose two.)

Accepted Answer

All ESXi hosts in the cluster must be connected to the same vDS.. NIOC operates at the vDS level and requires all hosts participating in the NIOC configuration to be attached to the same distributed switch. This ensures consistent network resource allocation and traffic shaping policies across the cluster. Option D is correct because NIOC is a premium feature that requires an Enterprise Plus license, as it leverages advanced resource management capabilities not available in lower license tiers.

Answer

Each ESXi host must have a dedicated vDS.

Answer

The vDS must have at least one uplink.

Answer

The physical switches must support LACP.

Question 14

An administrator wants to use vLCM to manage a cluster with 10 ESXi hosts. After enabling vLCM, what is the first step to ensure all hosts are running the same desired image?

Accepted Answer

Define a desired state image for the cluster.. With vLCM, the first step after enabling it on a cluster is to define a desired state image. This image specifies the exact ESXi version, firmware, and driver versions that all hosts in the cluster must match. Without defining this image, vLCM has no target configuration to validate or enforce against the hosts.

Answer

Remediate the cluster immediately to apply the default image.

Answer

Place all hosts into maintenance mode.

Answer

Create a host upgrade baseline and attach it to the cluster.

Question 15

Which THREE are valid methods to isolate and secure management traffic on a vSphere Distributed Switch? (Choose three.)

Accepted Answer

Assign a specific VLAN ID to the management port group.. Assigning a specific VLAN ID to the management port group isolates management traffic at Layer 2 by tagging frames with a unique VLAN identifier. This prevents unauthorized access from other VLANs and ensures that management traffic is logically separated from other network traffic on the same vSphere Distributed Switch.

Answer

Enable Route based on IP hash on the management port group.

Answer

Use Private VLANs on the management port group.
