VCP-VMC 2024 Question 34
Select 2An administrator is tasked with deploying a new virtual machine (VM) in a vSphere environment. The VM will host a database application requiring high storage performance and fault tolerance. Which of the following components should the administrator configure to meet the requirements?
- A
Use a Paravirtual SCSI (PVSCSI) adapter for the virtual machine's storage controller.
- B
Enable the VM's Fault Tolerance feature to ensure high availability.
- C
Use an NFS-based datastore for the VM's storage to maximize performance.
- D
Configure a RAID-5 policy on the physical storage backing the VM.
- E
Add multiple virtual NICs to the VM for network redundancy.
Show answer and explanation
Correct answers: A, B
Explanation
To meet the requirements of high storage performance and fault tolerance for a database application, the administrator should use a Paravirtual SCSI (PVSCSI) adapter for optimized storage I/O and enable the VM's Fault Tolerance feature for continuous availability. These configurations ensure minimal downtime and optimal performance for the application.
- A. Correct.
A Paravirtual SCSI (PVSCSI) adapter is optimized for high-performance storage I/O in VMware environments, making it ideal for database applications.
- B. Correct.
Fault Tolerance provides continuous availability by creating a live shadow instance of the VM, ensuring no downtime in case of a host failure.
- C. Incorrect.
While NFS-based datastores are supported, they are generally not the best choice for high-performance database workloads compared to block-based storage like VMFS or vSAN.
- D. Incorrect.
RAID-5 policies provide fault tolerance but are not optimized for high write performance, which is critical for database applications.
- E. Incorrect.
Adding multiple virtual NICs improves network redundancy but does not directly address storage performance or fault tolerance requirements.
