VCP-VVF IT Architectures Technologies Standards — 25 Questions

Question 1

An administrator is designing a new vSphere Foundation 9.0 cluster using 32-core AMD EPYC processors. Which hardware design standard must be verified to ensure maximum VM density and NUMA efficiency without cross-socket memory latency penalties?

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

Accepted Answer

Size virtual machine vCPUs to fit within the core and cache boundaries of a single physical NUMA node.. To maximize VM density and NUMA efficiency on AMD EPYC processors, VM vCPU counts should be sized to fit within a single physical NUMA node (core and cache boundaries). This avoids cross-socket memory access, which incurs higher latency and reduces performance. vSphere's NUMA scheduler places VMs on a single node when possible, but oversized VMs span nodes and suffer penalties.

Answer

Configure the hypervisor to span all vCPUs evenly across all sockets regardless of core counts.

Answer

Enable Fault Tolerance for every virtual machine to force physical socket load-balancing.

Answer

Disable hyperthreading globally across all hosts in the vCenter Server cluster settings.

Question 2

A data center architect is planning a vSphere Foundation 9.0 deployment utilizing NVMe-oF (NVMe over Fabrics) with TCP. Which architectural requirement is mandatory for the underlying physical network infrastructure?

Accepted Answer

Enforce a maximum transmission unit (MTU) of 9000 bytes across all physical switch ports and VMkernel adapters handling NVMe-oF traffic.. NVMe over Fabrics relies heavily on lossless or near-lossless low-latency packet delivery, making Jumbo Frames (MTU 9000) a standard architectural recommendation to reduce CPU overhead and fragmentation.

Answer

Configure spanning tree protocol (STP) with PortFast disabled on all access ports.

Answer

Implement static routing tables between every ESXi VMkernel port and storage controller.

Answer

Deploy Fibre Channel over Ethernet (FCoE) gateways on all top-of-rack switches.

Question 3

An infrastructure architect is configuring network security standards for a vSphere Foundation 9.0 environment. They want to ensure that all virtual machine traffic traversing a vSphere Distributed Switch cannot be sniffed by compromised guest operating systems using promiscuous mode. Which configuration setting must be enforced?

Accepted Answer

Set Promiscuous Mode, MAC Address Changes, and Forged Transmits to 'Reject' at the distributed port group security policy level.. Port group security policies on the vSphere Distributed Switch include Promiscuous Mode, MAC Address Changes, and Forged Transmits, which should be set to 'Reject' to prevent sniffing and spoofing.

Answer

Configure IP Source Guard on the physical switch access ports.

Answer

Deploy an external hardware tap appliance inline with the physical uplinks.

Answer

Enable BPDU Guard on all physical uplink switch ports connected to the ESXi host NICs.

Question 4

An administrator is reviewing host power management policies in a vSphere Foundation 9.0 cluster. To ensure compliance with strict application performance SLAs while achieving energy efficiency, which DPM (Distributed Power Management) and CPU power management standard should be implemented?

Accepted Answer

Configure ESXi power management policy to 'High Performance' and tune BIOS to OS-controlled or static maximum frequency.. To meet strict performance SLAs while still achieving energy efficiency, configure the ESXi power management policy to 'High Performance' and set the BIOS to OS-controlled or static maximum frequency. This ensures the host does not downclock CPUs in ways that add latency, while still allowing DPM to power off hosts when the cluster is idle. High Performance policy keeps CPUs at maximum frequency, and OS-controlled BIOS lets ESXi manage P-states deterministically.

Answer

Enable aggressive DPM with automated host power-off triggered every 5 minutes.

Answer

Disable Intel SpeedStep or AMD Cool'n'Quiet without specifying an ESXi power policy.

Answer

Set CPU power efficiency policy to maximum energy savings across all database nodes.

Question 5

An administrator is designing a vSphere Foundation 9.0 environment with high availability. Which component acts as the primary orchestrator for cluster-wide high availability (HA) failover actions if an ESXi host suffers a sudden power failure?

Accepted Answer

The elected HA Master ESXi host in the cluster.. In a vSphere HA cluster, the elected HA Master ESXi host is responsible for orchestrating cluster-wide HA failover actions. When a host suffers a sudden power failure, the HA Master detects the failure and coordinates the restart of affected virtual machines on other hosts in the cluster. The HA Master is elected from among the ESXi hosts and maintains the cluster's HA state.

Answer

The vSAN Witness Appliance residing at the secondary site.

Answer

The Platform Services Controller embedded in vCenter Server.

Answer

The external hardware load balancer connected to the vCenter Appliance.

Question 6

An administrator is setting up a new vSphere Foundation 9.0 cluster and needs to configure shared storage access using IP networks. Which VMkernel adapter service must be enabled to support software iSCSI storage traffic?

Accepted Answer

Software iSCSI traffic does not require a dedicated VMkernel service checkbox, but requires proper port binding to the iSCSI software adapter.. To use software iSCSI in ESXi, an administrator must enable the iSCSI service or bind a VMkernel port configured for iSCSI traffic.

Answer

The 'Fault Tolerance Logging' VMkernel service checkbox.

Answer

The 'Management' VMkernel service checkbox.

Answer

The 'vSphere Provisioning' VMkernel service checkbox.

Question 7

An IT planner is reviewing network topologies for a vSphere Foundation 9.0 environment. Which standard defines the encapsulation method used by Geneve tunnels when deployed with NSX in a modern data center design?

Accepted Answer

Geneve (Generic Network Virtualization Encapsulation). Geneve (Generic Network Virtualization Encapsulation) is the encapsulation protocol itself, defined in RFC 8926, and is the standard used by NSX for overlay tunnels in modern data center designs. It encapsulates Layer 2 frames within UDP, typically on port 6081, and supports extensible metadata via TLV options. NSX-T and later NSX versions use Geneve as the default overlay encapsulation.

Answer

VLAN tagging (IEEE 802.1Q)

Answer

Point-to-Point Tunneling Protocol (PPTP)

Answer

Fibre Channel over Ethernet (FCoE)

Question 8

An enterprise architect is designing a backup and recovery standard for a vSphere Foundation 9.0 environment. Which technology should be integrated with vCenter Server to enable efficient, crash-consistent or application-consistent virtual machine snapshots without placing heavy processing loads on the ESXi host CPU?

Accepted Answer

vSphere APIs for Data Protection (VADP) utilizing Changed Block Tracking (CBT).. vSphere APIs for Data Protection (VADP) allow backup vendors to offload snapshot creation and data transport using Changed Block Tracking (CBT).

Answer

Network I/O Control bandwidth throttling shares.

Answer

Fault Tolerance continuous replication logs.

Answer

Storage DRS inter-datastore cloning.

Question 9

A systems architect is evaluating storage policy designs for a vSAN datastore in a vSphere Foundation 9.0 cluster. When configuring the Failures to Resist (FTT) policy using Erasure Coding (RAID-5/6), what is the minimum number of host fault domains required for a RAID-5 storage policy?

Accepted Answer

At least 4 fault domains (hosts). RAID-5 Erasure Coding in vSAN requires a minimum of 4 fault domains (hosts) to distribute data and parity blocks effectively.

Answer

At least 3 fault domains (hosts)

Answer

At least 6 fault domains (hosts)

Answer

At least 2 fault domains (hosts)

Question 10

An architect is planning the port requirements for a vSphere Foundation 9.0 environment. Which standard TCP port must be open on firewalls between ESXi hosts and vCenter Server for primary agent communication (vpxa)?

Accepted Answer

TCP port 902. TCP port 902 is used by vCenter Server to communicate with the heartbeat agent (vpxa) on ESXi hosts.

Answer

TCP port 1433

Answer

TCP port 3389

Answer

TCP port 80

Question 11

An administrator is designing a vSphere Foundation 9.0 cluster and needs to enable Enhanced Data Protection for virtual machines. Which vCenter feature works in conjunction with vSphere Trust Authority to ensure keys are released only to verified, trusted ESXi hosts?

Accepted Answer

vSphere Trust Authority (vTA). vSphere Trust Authority (vTA) is the vCenter feature that establishes a trust relationship between ESXi hosts and a trusted cluster, ensuring that encryption keys are released only to hosts whose attestation proves they are in a known-good state. It works with the Key Provider Service and attestation to gate key release. This is the mechanism that underpins Enhanced Data Protection for VMs.

Answer

Enhanced vMotion Compatibility baselines.

Answer

High Availability host isolation responses.

Answer

Storage DRS automated placement rules.

Question 12

An administrator is designing a vSphere Foundation 9.0 environment and needs to deploy the vCenter Server Appliance. Which deployment size should be selected for a medium enterprise environment managing up to 400 hosts and 4,000 virtual machines?

Accepted Answer

Select the appropriate deployment size (such as Small or Medium) matching the host and VM count guidelines in the VMware Configuration Maximums documentation.. VMware publishes deployment-size guidelines in the Configuration Maximums documentation that map host and VM counts to Tiny, Small, Medium, Large, and X-Large vCenter Server Appliance profiles. For up to 400 hosts and 4,000 VMs, the administrator should select the size that matches those published guidelines rather than guessing or defaulting to Tiny.

Answer

Utilize the unconfigured default template without assigning any CPU or memory resources.

Answer

Deploy vCenter as a physical Windows Server 2025 cluster with SQL Server.

Answer

Always select the 'Tiny' deployment size to conserve disk space regardless of host counts.

Question 13

An administrator is designing a vSphere Foundation 9.0 cluster. When configuring high availability (HA) admission control, which admission control policy is recommended to ensure sufficient resources are reserved for failover without over-complicating capacity math?

Accepted Answer

Percentage of Cluster Resources reserved for CPU and Memory.. Host failures to tolerate (FTT) or Percentage of Cluster Resources are standard, modern HA admission control policies that automatically scale as cluster size changes.

Answer

Static manual reservation of 32 physical CPU cores per virtual machine.

Answer

Routing failover requests through an external public cloud broker.

Answer

Disabling admission control entirely to allow 100% resource overcommit.

Question 14

An IT architect is evaluating storage policy options for a vSAN datastore in a vSphere Foundation 9.0 cluster. Which THREE storage policy rules can be enforced via vSAN storage policies? (Choose three.)

Accepted Answer

Failures to Resist (FTT / RAID level configuration). Option A (Failures to Resist / RAID level configuration) is correct because vSAN storage policies define the number of failures to tolerate (FTT) and the corresponding RAID-1/RAID-5/RAID-6 configuration that determines how many host, disk, or rack failures the datastore can survive. Option C (Flash Read Cache Reservation) is correct because vSAN storage policies include a Flash Read Cache Reservation setting (expressed as a percentage of the object's logical size) that reserves flash capacity for read cache on hybrid configurations. Option E (Disk Stripe Width) is correct because vSAN storage policies let you set the number of disk stripes per object to improve performance by spreading I/O across multiple capacity devices. Option B is incorrect because VLAN reconfiguration on physical switch ports is a network administration task handled by the switch, not a vSAN storage policy rule. Option D is incorrect because Active Directory password complexity is governed by domain Group Policy or fine-grained password policies, not by vSAN storage policies.

Answer

Automatic physical switch port VLAN reconfiguration

Answer

Active Directory domain controller password complexity rules

Question 15

An administrator is designing a vSphere Foundation 9.0 cluster and needs to configure networking redundancy. Which TWO teaming and failover methods are supported on vSphere Distributed Switches? (Choose two.)

Accepted Answer

Route Based on Originating Virtual Port. VDS support multiple teaming policies including Route Based on Originating Virtual Port and Route Based on IP Hash.

Answer

Border Gateway Protocol Autonomous System Path Prepending

Answer

Spanning Tree Protocol Root Bridge Selection

Answer

Point-to-Point Serial Line Framing

Question 16

An enterprise architect is planning virtual machine resource controls in a vSphere Foundation 9.0 cluster. Which THREE parameters can be configured on a virtual machine's CPU or memory settings? (Choose three.)

Accepted Answer

Shares. In vSphere, a virtual machine's CPU and memory resource settings expose three standard allocation controls: Shares (B), Limit (C), and Reservation (D). Shares (B) set the relative priority of the VM within a resource pool or host when contention occurs, expressed as High/Normal/Low or a custom numeric value. Reservation (C) guarantees a minimum amount of CPU (MHz) or memory (MB) that the VM is entitled to, and Limit (D) caps the maximum CPU or memory the VM may consume, both configurable per VM. Physical Socket Count Multiplexing (A) is not a real vSphere VM CPU parameter — socket count is set via 'Number of virtual sockets' and cores per socket, not multiplexing. BIOS Voltage Scaling Factor (E) is not a vSphere resource control at all; power management is handled at the host/BIOS level, not as a per-VM CPU or memory setting.

Answer

Physical Socket Count Multiplexing

Answer

BIOS Voltage Scaling Factor

Question 17

An administrator is designing a vSphere Foundation 9.0 environment and needs to configure vCenter Server Single Sign-On (SSO) identity sources. Which THREE identity source types are natively supported by vCenter Server SSO? (Choose three.)

Accepted Answer

Local OS users (local vpxuser / local system accounts). Option B is correct because vCenter Server SSO natively supports Local OS users, allowing authentication against the local operating system accounts on the vCenter Server host (for example, local vpxuser/system accounts) as an identity source. Option D is correct because Active Directory is a natively supported SSO identity source, configurable either via Integrated Windows Authentication (IWA) or as Active Directory over LDAP. Option E is correct because OpenLDAP directory services are also natively supported as an SSO identity source type in vCenter Server. Option A does not belong because anonymous guest web tokens via public web scrapers are not an SSO identity source type. Option C does not belong because local Bluetooth pairing with mobile smartphones is not an authentication mechanism supported by vCenter Server SSO.

Answer

Anonymous guest web tokens via public web scrapers

Answer

Local Bluetooth pairing with mobile smartphones

Question 18

An administrator is designing a vSphere Foundation 9.0 cluster and configuring vSphere HA response actions. Which TWO configurable actions can vSphere HA take when a host isolation event is detected (Host Isolation Response)? (Choose two.)

Accepted Answer

Leave virtual machines powered on. The Host Isolation Response in vSphere HA defines what happens to VMs running on an ESXi host that has lost management network connectivity to the cluster. Option A (Leave virtual machines powered on) is correct because this is the default and recommended setting; the host keeps its VMs running, and the master host does not attempt to restart them elsewhere, avoiding unnecessary downtime and split-brain risk. Option B (Power off virtual machines) is also correct because vSphere HA can be configured to power off the isolated host's VMs, allowing the master host to restart them on healthy hosts in the cluster (or, in newer versions, the 'Power off and restart' behavior). Option C is wrong because reformatting datastores with VMFS-6 is not a vSphere HA isolation action and would destroy data. Option D is wrong because permanently decommissioning an ESXi motherboard is a hardware lifecycle task, not an HA response. Option E is wrong because vSphere HA does not migrate VMs to AWS EC2; that would require a separate hybrid-cloud or disaster-recovery solution.

Answer

Reformat all attached datastores with VMFS-6

Answer

Permanently decommission the ESXi motherboard

Answer

Instantly migrate all VMs to public cloud AWS EC2 instances

Question 19

An enterprise architect is planning a vSphere Foundation 9.0 upgrade using vSphere Lifecycle Manager (vLCM). Which THREE components can be managed and validated as part of a vLCM single cluster image? (Choose three.)

Accepted Answer

ESXi base image version. In vSphere Lifecycle Manager, a cluster image is composed of three managed layers: the ESXi base image (option A), which defines the ESXi version and its core VIBs; the Vendor Add-on (option C), which supplies the hardware vendor's driver and firmware bundle validated for that server platform; and Firmware and Driver Add-ons (option D), which deliver additional component-level firmware and driver updates beyond the vendor add-on. These three elements are exactly what vLCM composes, remediates, and validates against the desired state of the cluster image. Option B is incorrect because top-of-rack switch firmware is network infrastructure managed outside vLCM, not part of a cluster image. Option E is incorrect because guest OS patching is handled by tools like vSphere Configuration Profiles, vRealize/VMware Aria Operations, or Microsoft update mechanisms, not by vLCM cluster images.

Answer

Top-of-rack physical switch firmware images

Answer

Microsoft Windows Server guest operating system patches

Question 20

An infrastructure architect is designing a vSphere Foundation 9.0 cluster and evaluating advanced storage policies for vSAN. Which THREE data services are native to vSAN and configurable via storage policies? (Choose three.)

Accepted Answer

Deduplication and Compression. Option A (Deduplication and Compression) is correct because vSAN natively supports space efficiency features that can be enabled and controlled through vSAN storage policies, allowing block-level deduplication and compression on supported all-flash configurations. Option C (Encryption, Data-at-Rest Encryption) is correct because vSAN provides native data-at-rest encryption, and enabling it is governed by storage policy settings such as the encryption rule tied to a KMS. Option E (Checksum, automatic integrity checking and self-healing) is correct because vSAN performs automatic checksum verification and self-healing to detect and repair silent data corruption, and these integrity behaviors are part of vSAN's native data services configurable via policy. Option B is incorrect because replacing a failed physical server chassis motherboard is a hardware service action, not a vSAN data service or storage policy setting. Option D is incorrect because automatic physical fibre channel cable weaving is not a vSAN capability; vSAN is a software-defined storage solution and does not manage physical FC cabling.

Answer

Automated replacement of failed physical server chassis motherboards

Answer

Automatic physical fibre channel cable weaving
