VCP-VMC 2024 Question 33
Select 2An administrator is tasked with deploying a new virtual machine (VM) in a VMware vSphere environment. The VM needs to have high-performance disk storage and must maintain its state even if the host fails. Which virtual machine components should the administrator configure to meet these requirements?
- A
Use a virtual disk stored on a shared datastore with redundancy.
- B
Enable snapshots to ensure VM state can be restored after a failure.
- C
Attach a virtual NVMe controller for high-performance disk I/O.
- D
Use a physical RDM (Raw Device Mapping) for direct access to a physical LUN.
- E
Configure a virtual floppy disk to store critical data backups.
Show answer and explanation
Correct answers: A, C
Explanation
To meet the requirements, the administrator should configure a virtual disk on a shared datastore with redundancy, which ensures that the VM's data is protected and accessible even if the host fails. Adding a virtual NVMe controller further enhances the storage performance, making it suitable for high-performance workloads. Snapshots and physical RDMs do not fully address the requirements, and virtual floppy disks are obsolete in modern environments.
- A. Correct.
Using a virtual disk stored on a shared datastore with redundancy ensures that the VM's state and data are protected in the event of a host failure through technologies like vSphere HA and shared storage.
- B. Incorrect.
While snapshots provide a way to revert the VM to a previous state, they are not a solution for maintaining VM state or performance during a host failure. Snapshots are not intended for long-term use or high-performance environments.
- C. Correct.
Attaching a virtual NVMe controller provides high-performance storage access, which aligns with the requirement for high-performance disk I/O.
- D. Incorrect.
A physical RDM allows direct access to a physical LUN but is not optimal for shared storage or redundancy in a high-availability environment.
- E. Incorrect.
A virtual floppy disk is outdated and not suitable for storing critical data backups or ensuring high performance.
