VCP-VVF Practice Questions

Question 1

An enterprise architect is planning a vSphere Foundation 9.0 upgrade and needs to ensure that vCenter Server supports Enhanced Linked Mode (ELM). What is the architectural requirement for ELM across multiple vCenter instances?

Accepted Answer

All participating vCenter Server appliances must belong to the same Single Sign-On (SSO) domain during or after deployment.. Enhanced Linked Mode allows administrators to view and manage multiple vCenter servers from a single interface, requiring them to be joined to the same vCenter Single Sign-On (SSO) domain.

Answer

Cross-vCenter Enhanced Linked Mode requires all hosts to run identical CPU models from different vendors.

Answer

The underlying ESXi hosts must be managed by a single master physical blade chassis.

Answer

All vCenter instances must share the exact same external Microsoft SQL database instance.

Question 2

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.. Setting the host BIOS and ESXi power management policy to 'High Performance' or 'Static' prevents CPU P-state/C-state latency overheads that could impact sensitive latency-critical applications.

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 3

An enterprise architect is designing a backup and recovery architecture for vSphere Foundation 9.0 virtual machines. Which THREE data transport modes are supported by modern backup software leveraging VADP (vSphere APIs for Data Protection)? (Choose three.)

Accepted Answer

HotAdd mode (attaching virtual disks to a backup proxy virtual machine). VADP supports multiple backup transport modes including HotAdd, SAN (Direct SAN access), and NBD/NBDSSL (Network Block Device).

Answer

Analog modem dial-up SLIP protocol

Answer

Bluetooth wireless PAN streaming

Question 4

An administrator is designing a vSphere Foundation 9.0 cluster and wishes to implement Network I/O Control (NIOC) version 3 to manage traffic contention on 10GbE/25GbE uplinks. How does NIOC prioritize traffic across system traffic types?

Accepted Answer

By allocating user-defined shares and reservation percentages to specific system traffic types on the distributed switch uplinks.. NIOC version 3 uses shares, reservation, and limits applied to defined system traffic types (such as vMotion, FT, vSAN, iSCSI, NFS, and Management) on the distributed switch.

Answer

By enforcing strict packet drop rules on management traffic when vMotion exceeds 80% utilization.

Answer

By rewriting DSCP bits on physical core switch headers directly.

Answer

By dynamically migrating virtual machines to less congested physical switches using BGP routing.

Question 5

An IT architect is designing a backup solution for a vSphere Foundation 9.0 vCenter Server Appliance. Which recommended standard should be established for protecting the VCSA configuration?

Accepted Answer

Configure scheduled File-Based Backup (Native Backup) from the VCSA management interface (Appliance Management UI / port 5480).. vCenter Server Appliance Native Backup (file-based backup) scheduled regularly provides a fast and reliable method to back up VCSA configurations, certificates, and database metadata.

Answer

Export the vCenter database tables manually using Microsoft Access via ODBC.

Answer

Take guest operating system level screenshots every 10 minutes using a desktop recorder.

Answer

Rely solely on physical top-of-rack switch configuration backups.

Question 6

An administrator is preparing to deploy vCenter Server 9.0 in a high-availability architecture. What is the fundamental prerequisite regarding DNS for the vCenter Server Appliance (VCSA) deployment?

Accepted Answer

Configured Forward (A) and Reverse (PTR) DNS records corresponding to the VCSA FQDN.. VCSA deployment requires valid Forward (A) and Reverse (PTR) DNS records to ensure reliable identification and certificate generation.

Answer

Static ARP entries mapped on all upstream core routing devices.

Answer

Network Time Protocol (NTP) disabled during the initial installation wizard.

Answer

Active Directory domain controller roles installed directly onto the appliance OS.

Question 7

An administrator is designing a vSphere Foundation 9.0 cluster and wants to optimize memory resource utilization across virtual machines. Which memory management technique reclaims idle memory from running VMs by temporarily reallocating it to VMs experiencing memory pressure?

Accepted Answer

Memory ballooning via the VMware Tools balloon driver (vmmemctl).. Transparent Page Sharing (TPS) and memory ballooning are classic hypervisor memory reclamation techniques; ballooning actively reclaims allocated guest memory.

Answer

Enabling Fibre Channel multipathing round-robin policies.

Answer

Upgrading physical RAM modules without rebooting the ESXi host.

Answer

Forcibly killing guest operating system background services using remote SSH commands.

Question 8

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 9

An enterprise architect is integrating vSphere Foundation 9.0 with an external hardware security module (HSM) cluster using KMIP. Which architectural standard ensures that vCenter Server securely establishes keys for VM encryption without exposing cleartext credentials?

Accepted Answer

Mutual TLS (mTLS) certificate authentication combined with KMIP-compliant key exchange.. KMIP (Key Management Interoperability Protocol) version 1.1 or higher establishes secure mutual TLS authentication and cryptographic operations between vCenter and the HSM.

Answer

IPsec transport mode tunnels terminated on the ESXi management vmkernel interface.

Answer

OAuth 2.0 token exchange via the vCenter Lookup Service.

Answer

LDAP over SSL (LDAPS) binding using shared secret service accounts.

Question 10

A security architect is hardening a vSphere Foundation 9.0 environment and needs to restrict access to the ESXi host CIM (Common Information Model) service. Which design practice aligns with modern security hardening standards?

Accepted Answer

Disable the CIM server service on ESXi hosts if hardware monitoring is handled out-of-band via IPMI/iLO/iDRAC.. Disabling unused or insecure management services like CIM (or restricting access) reduces the attack surface of the ESXi hypervisor.

Answer

Grant CIM access permissions to all authenticated Active Directory users.

Answer

Configure the CIM service to use unencrypted HTTP ports for faster hardware polling.

Answer

Route all CIM traffic through the vCenter Server database layer.

Question 11
