VCP Technology & Digital Tools 4 — Questions and Answers
Question 1: Which vSphere feature provides zero-downtime protection for VMs by maintaining a continuous mirror of a running VM on a secondary host?
- vSphere Fault Tolerance (FT) (Correct answer)
- vSphere High Availability (HA)
- vSphere DRS
- vSphere Replication
Correct answer: vSphere Fault Tolerance (FT)
vSphere Fault Tolerance maintains a live shadow VM on a secondary host that continuously mirrors the primary VM's execution state, providing zero RPO and zero RTO protection.
Question 2: A vSphere admin uses PowerCLI to script infrastructure tasks. What is PowerCLI built upon?
- Windows PowerShell and .NET Framework (Correct answer)
- Python with REST API bindings
- Bash shell with SOAP API calls
- Java SDK with CLI wrappers
Correct answer: Windows PowerShell and .NET Framework
VMware PowerCLI is a collection of PowerShell modules built on the .NET Framework that provide cmdlets for managing vSphere, NSX, vSAN, and other VMware products.
Question 3: What is the role of the vSphere vCenter Server in a VMware infrastructure?
- Centralized management platform for ESXi hosts and VMs (Correct answer)
- Hypervisor that runs directly on physical hardware
- Network virtualization controller for NSX
- Storage policy enforcement engine for vSAN
Correct answer: Centralized management platform for ESXi hosts and VMs
vCenter Server is the centralized management platform that provides a single pane of glass for managing multiple ESXi hosts, VMs, clusters, and advanced features like DRS, HA, and vMotion.
Question 4: Which VMware feature enables administrators to enforce compliance and desired-state configuration across ESXi hosts using baseline profiles?
- vSphere Lifecycle Manager (vLCM) (Correct answer)
- vSphere Update Manager (VUM)
- VMware Skyline
- vSphere Configuration Profiles
Correct answer: vSphere Lifecycle Manager (vLCM)
vSphere Lifecycle Manager (vLCM) manages the lifecycle of ESXi hosts using image-based or baseline-based remediation to enforce compliance across the cluster.
Question 5: Which vSphere storage technology allows administrators to pool local flash and HDD storage across ESXi hosts to create a shared datastore?
- vSAN (Virtual SAN) (Correct answer)
- VMFS datastore on shared FC SAN
- NFS datastore on NAS array
- Raw Device Mapping (RDM)
Correct answer: vSAN (Virtual SAN)
VMware vSAN aggregates local storage devices (SSDs and HDDs) from multiple ESXi hosts into a distributed, shared datastore managed through storage policies.
Question 6: What does the vSphere API for I/O Filtering (VAIO) enable third-party vendors to provide?
- In-path data services like caching and replication at the hypervisor layer (Correct answer)
- Direct hardware access for VMs bypassing the hypervisor
- Automated VM placement based on I/O metrics
- Storage array offload for deduplication and compression
Correct answer: In-path data services like caching and replication at the hypervisor layer
VAIO allows third-party vendors to insert I/O filter modules into the VM data path to provide services such as caching, replication, and encryption at the hypervisor level.
Question 7: An administrator wants to capture a point-in-time state of a VM including memory, disk, and settings. Which technology should be used?
- VM Snapshot (Correct answer)
- vSphere Replication
- VM Clone
- vSphere Fault Tolerance
Correct answer: VM Snapshot
A VM snapshot captures the complete state of a VM including its memory contents, virtual disk state, and VM settings at a specific point in time.
