VCP-VCF Administrator 2024 Question 199
Select 2You are managing a VMware Cloud Foundation environment and are tasked with implementing a VM storage policy to ensure that a mission-critical VM benefits from high availability and performance. The storage infrastructure includes vSAN with deduplication and compression enabled. Which configuration should you include in the VM storage policy?
- A
Set 'Failures to Tolerate' (FTT) to 1 with RAID-1 (Mirroring)
- B
Set 'Failures to Tolerate' (FTT) to 2 with RAID-5 (Erasure Coding)
- C
Enable 'Force Provisioning' to bypass storage compliance checks
- D
Set the 'Object Space Reservation' to 100%
- E
Enable 'IOPS Limit for Object' at 1000
Show answer and explanation
Correct answers: B, D
Explanation
For mission-critical VMs, it is essential to balance high availability, performance, and storage efficiency. Configuring 'Failures to Tolerate' (FTT) to 2 with RAID-5 provides redundancy while optimizing storage space in a vSAN environment with deduplication and compression. Additionally, setting the 'Object Space Reservation' to 100% guarantees full provisioning of storage resources, ensuring consistent performance. These choices align with best practices for managing critical workloads in VMware Cloud Foundation.
- A. Incorrect.
Setting 'Failures to Tolerate' (FTT) to 1 with RAID-1 (Mirroring) provides high availability, but RAID-1 consumes more storage space and may not be the most efficient choice in environments using deduplication and compression.
- B. Correct.
Setting 'Failures to Tolerate' (FTT) to 2 with RAID-5 (Erasure Coding) provides both high availability and efficient storage utilization, making it suitable for mission-critical VMs in a vSAN environment with deduplication and compression enabled.
- C. Incorrect.
Enabling 'Force Provisioning' is not recommended for mission-critical workloads because it bypasses compliance checks, which could result in suboptimal or unsupported configurations.
- D. Correct.
Setting the 'Object Space Reservation' to 100% ensures that the storage object is fully provisioned, which is important for guaranteeing performance for mission-critical workloads.
- E. Incorrect.
Enabling 'IOPS Limit for Object' at 1000 limits the performance of the VM's storage, which is undesirable for mission-critical workloads requiring high performance.
