VCP-DCV Practice Test 36 — 15 Questions

Question 1

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?

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

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 2

An organization has deployed a vSphere Distributed Switch (vDS) across multiple ESXi hosts. The security team requires that no virtual machine can change its MAC address to impersonate another device. Which security policy setting on the distributed port group should be configured to fulfill this requirement?

Accepted Answer

Set 'Forged transmits' to 'Reject'.. The 'Forged transmits' policy, when set to 'Reject', drops any outbound frames with a source MAC address different from the one assigned to the virtual NIC. This prevents a VM from impersonating another device by spoofing its MAC address. Option B is incorrect because 'MAC address changes' controls whether the VM can change its effective MAC address, but this does not prevent the VM from sending frames with a forged source MAC. Option C is incorrect because 'Promiscuous mode' allows the VM to see all traffic on the port, which is a security risk but unrelated to MAC impersonation. Option D is incorrect because traffic shaping limits bandwidth, not MAC security.

Answer

Set 'MAC address changes' to 'Reject'.

Answer

Set 'Promiscuous mode' to 'Reject'.

Answer

Enable traffic shaping and set a low average bandwidth.

Question 3

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 4

A vSphere environment experiences periodic performance degradation during peak business hours. Analysis shows that one ESXi host's CPU ready time for a specific mission-critical VM is consistently above 20%. Which corrective action should be taken first?

Accepted Answer

Migrate the VM to a different host with lower CPU utilization. High ready time indicates CPU contention. Moving the VM to a less loaded host using DRS or manual migration can immediately reduce ready time. Increasing resources without addressing contention is ineffective.

Answer

Increase the VM's memory reservation

Answer

Set a higher CPU limit on the VM

Answer

Add more vCPUs to the VM

Question 5

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 6

A company has a vSphere 7.0 cluster with 6 ESXi hosts connected to a Dell EMC PowerStore array using iSCSI. They are using VMFS6 datastores. After a recent firmware upgrade on the array, they notice that performance on one datastore has degraded significantly. The datastore is used by several high-I/O VMs. The administrator runs 'esxcli storage core path list' and sees that all paths to that datastore are active but with varying latency. The PSP is set to Round Robin with IOPS limit of 1000. The SATP is VMW_SATP_ALUA. The storage administrator confirms that the array is in active-active mode. What should the administrator do to improve performance?

Accepted Answer

Increase the Round Robin IOPS limit to 10000.. The Round Robin PSP with an IOPS limit of 1000 is causing the ESXi host to switch paths too frequently, which can lead to higher latency due to path thrashing and suboptimal use of the array's active-active ALUA mode. Increasing the Round Robin IOPS limit to 10000 reduces the frequency of path switches, allowing each path to handle more I/Os before switching, which improves performance for high-I/O workloads on VMFS6 datastores.

Answer

Enable the array's QoS policy and configure the datastore for VAAI.

Answer

Change the PSP to Most Recently Used (MRU) to reduce path thrashing.

Answer

Change the SATP to VMW_SATP_DEFAULT_AA and reconfigure the iSCSI initiator.

Question 7

An administrator notices that a VMFS datastore has only one optimized path. The exhibit shows the output of esxcli storage nmp path list for that datastore. What should the administrator do to fully utilize both storage controllers?

Accepted Answer

Change the SATP to VMW_SATP_ALUA.. The exhibit shows only one optimized path because the storage array uses Asymmetric Logical Unit Access (ALUA), which requires the VMW_SATP_ALUA SATP to properly recognize and manage both active/optimized and active/non-optimized paths. With the default SATP (e.g., VMW_SATP_DEFAULT_AA), the host treats all paths as active but fails to distinguish optimized from non-optimized paths, often resulting in only one path being used. Changing to VMW_SATP_ALUA allows the host to correctly identify the optimized path and actively use both storage controllers for load balancing.

Answer

Rescan the storage adapters.

Answer

Change the PSP to Round Robin.

Answer

Enable the path failover policy.

Question 8

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 9

A vSphere administrator needs to ensure that a critical VM restarts automatically if the ESXi host fails. Which feature should be configured?

Accepted Answer

vSphere HA. vSphere HA provides host failure detection and automatic restart of VMs.

Answer

vSphere vMotion

Answer

vSphere DRS

Answer

vSphere Fault Tolerance

Question 10

An administrator sees that a vLCM remediation task for a host has failed with the error: 'The VIB is incompatible with the host's base image.' The host is using a custom image that includes a third-party driver. What is the most likely cause?

Accepted Answer

The VIB version is not compatible with the ESXi version in the image.. A VIB incompatible with the base image typically indicates a version mismatch or dependency issue; updating the VIB to a compatible version resolves this. Option A is wrong because the VIB is present but incompatible. Option C is wrong because you cannot simply skip incompatible VIBs. Option D is wrong because removing the VIB may break hardware functionality.

Answer

The third-party driver should be removed from the image.

Answer

The VIB is missing from the cluster image.

Answer

The administrator should ignore the error and proceed.

Question 11

Which TWO of the following are prerequisites for enabling jumbo frames on a vSphere host for storage traffic?

Accepted Answer

The VMkernel port must be configured with MTU 9000. Jumbo frames require physical switch support and VMkernel port MTU configuration. The storage array, guest OS, and vCenter do not directly affect host-level jumbo frame operation.

Answer

The virtual machine guest OS must support jumbo frames

Answer

The storage array must support jumbo frames

Answer

The vCenter Server must be configured for jumbo frames

Question 12

An administrator wants to use Storage DRS to balance space usage across datastores. What must be configured?

Accepted Answer

Storage DRS automation level. The storage DRS automation level (manual, partially automated, fully automated) controls whether migration recommendations are generated or applied automatically. SIOC, policies, and host affinity are not required for space balancing.

Answer

Host affinity rules

Answer

SIOC

Answer

Storage policy

Question 13

Which two factors most directly influence vSphere NUMA scheduling decisions for a VM? (Choose two.)

Accepted Answer

Host NUMA node topology. The correct options are A and C. vSphere NUMA scheduling uses the number of vCPUs and the host NUMA node topology to place the VM on a single node. Memory reservation and VM version are secondary. Storage policy is not relevant.

Answer

VM memory reservation

Answer

VM storage policy

Answer

Virtual machine version

Question 14

An administrator is configuring a vSAN cluster with all-flash capacity. The cluster uses RAID-5 erasure coding with a policy of 'Number of failures to tolerate = 1' (PFTT=1). The administrator wants to minimize storage overhead while ensuring availability. Which vSAN storage policy setting should be used?

Accepted Answer

Set 'Primary level of failures to tolerate' to 1 and 'Primary level of failures to tolerate method' to 'RAID-5 (Erasure Coding)'. For all-flash vSAN, RAID-5/6 erasure coding is recommended. With PFTT=1, RAID-5 requires only 1 parity component, minimizing overhead. Option C is correct. Option A (RAID-1 mirroring) would use more capacity. Option B (RAID-6) is for PFTT=2 and adds more overhead. Option D (no redundancy) is not fault tolerant.

Answer

Set 'Primary level of failures to tolerate' to 1 and 'Primary level of failures to tolerate method' to 'RAID-1 (Mirroring)'

Answer

Set 'Primary level of failures to tolerate' to 2 and 'Primary level of failures to tolerate method' to 'RAID-6 (Erasure Coding)'

Answer

Set 'Primary level of failures to tolerate' to 0

Question 15

Based on the exhibit, which statement about the virtual machine's memory state is TRUE?

Accepted Answer

The VM is actively swapping memory because of memory pressure.. SWCUR (current swapped memory) is 512 MB, and SWR/s and SWW/s show non-zero swap rates, indicating that the VM is actively swapping memory to disk. MCTLSZ is 0, meaning no ballooning is occurring. The VM's memory size is 4096 MB. Swapping is a sign of memory pressure.

Answer

The VM is using the memory balloon driver to reclaim memory.

Answer

The VM is using transparent page sharing to reduce memory usage.

Answer

The VM has no memory pressure and is performing optimally.
