VCP VMware Certified Professional 2 — Questions and Answers
Question 1: Which vSphere component is responsible for managing virtual machine files and datastores on an ESXi host?
- vCenter Server
- vSphere Web Client
- VMkernel (Correct answer)
- vSphere Data Services
Correct answer: VMkernel
The VMkernel is the core OS of ESXi that manages hardware resources, including storage I/O and datastore access for VMs.
Question 2: A VM is configured with a VMXNET3 network adapter. What is a primary advantage of VMXNET3 over the E1000 adapter?
- It requires no VMware Tools installation
- It supports higher throughput with lower CPU overhead (Correct answer)
- It is compatible with all legacy guest OSes
- It provides hardware-level encryption
Correct answer: It supports higher throughput with lower CPU overhead
VMXNET3 is a paravirtualized adapter designed for performance, offering higher throughput and significantly reduced CPU overhead compared to E1000.
Question 3: What is the default port used by vCenter Server for HTTPS management traffic?
- 80
- 443 (Correct answer)
- 902
- 9443
Correct answer: 443
Port 443 is the standard HTTPS port used for vSphere Client and API connections to vCenter Server.
Question 4: Which vSphere feature allows you to encrypt virtual machine disks at rest without modifying the guest OS?
- vSphere Replication
- vSphere VM Encryption (Correct answer)
- VMware HCX
- vSAN Deduplication
Correct answer: vSphere VM Encryption
vSphere VM Encryption encrypts VM files, including VMDK files, at the hypervisor level without requiring guest OS changes.
Question 5: What happens to a virtual machine's memory balloon when the ESXi host is under memory pressure?
- The balloon driver deflates to free guest memory
- The balloon driver inflates, reclaiming guest memory for the host (Correct answer)
- The VM is immediately migrated to another host
- The VM's memory reservation is automatically increased
Correct answer: The balloon driver inflates, reclaiming guest memory for the host
Under host memory pressure, the balloon driver in the guest OS inflates, forcing the guest to reclaim and page out its own memory, which the host then reuses.
Question 6: Which permission model component in vCenter determines what actions a user can perform on an object?
- User account
- Role (Correct answer)
- Privilege
- Group
Correct answer: Role
A role is a collection of privileges, and assigning a role to a user on an object determines what actions that user can perform.
Question 7: In a vSphere HA cluster, what is the purpose of the 'Admission Control' policy?
- To prevent unauthorized users from powering on VMs
- To reserve cluster resources so failover capacity is always available (Correct answer)
- To limit the number of snapshots per VM
- To enforce DRS rules during VM placement
Correct answer: To reserve cluster resources so failover capacity is always available
Admission Control ensures that enough host resources are reserved in the cluster to restart VMs from failed hosts during a failover event.
