VCP Data Center Virtualization 2 — Questions and Answers
Question 1: Which vSphere feature allows a virtual machine to be moved from one ESXi host to another without any downtime?
- Storage vMotion
- vMotion (Correct answer)
- Fault Tolerance
- High Availability
Correct answer: vMotion
vMotion enables live migration of running VMs between ESXi hosts with zero downtime by transferring memory state over the network.
Question 2: What is the maximum number of vCPUs supported per virtual machine in vSphere 8?
- 64
- 128
- 256 (Correct answer)
- 512
Correct answer: 256
vSphere 8 supports up to 256 vCPUs per virtual machine, enabling workloads requiring massive parallel processing.
Question 3: In VMware vSAN, what is the purpose of the 'failures to tolerate' (FTT) policy?
- Defines the number of snapshots allowed per VM
- Specifies how many host or disk failures the cluster can sustain without data loss (Correct answer)
- Sets the maximum IOPS for a storage object
- Determines the stripe width for performance optimization
Correct answer: Specifies how many host or disk failures the cluster can sustain without data loss
The FTT policy in vSAN determines how many simultaneous host or disk failures the cluster can endure while maintaining data availability.
Question 4: Which VMware component is responsible for providing distributed firewall capabilities at the hypervisor level?
- VMware NSX (Correct answer)
- vSphere Distributed Switch
- vCenter Server
- VMware Aria Operations
Correct answer: VMware NSX
VMware NSX provides a distributed firewall that enforces microsegmentation policies at the vNIC level on each ESXi host.
Question 5: What happens to virtual machines running on an ESXi host when HA is triggered due to host failure?
- VMs are permanently deleted
- VMs are restarted on surviving hosts in the cluster (Correct answer)
- VMs are migrated live to other hosts
- VMs enter a suspended state until the host recovers
Correct answer: VMs are restarted on surviving hosts in the cluster
vSphere HA detects host failure and automatically restarts the affected VMs on remaining healthy hosts in the cluster.
Question 6: Which storage policy component in vSAN defines how data is distributed across disk groups for performance?
- Number of disk stripes per object (Correct answer)
- Failures to tolerate
- Object space reservation
- Flash read cache reservation
Correct answer: Number of disk stripes per object
The 'number of disk stripes per object' policy controls how many capacity devices each storage object is striped across, affecting performance.
Question 7: In a vSphere cluster, what is the role of the vCenter Server?
- Provides the hypervisor kernel for running VMs
- Manages and orchestrates ESXi hosts and their resources centrally (Correct answer)
- Handles VM-to-VM network traffic switching
- Stores virtual machine disk files
Correct answer: Manages and orchestrates ESXi hosts and their resources centrally
vCenter Server is the centralized management platform that provides orchestration, monitoring, and administration for ESXi hosts and VMs in a cluster.
