Exam 3V0-23.25 Topic 1 Question 59 Discussion

Actual exam question for VMware's 3V0-23.25 exam
Question #: 59
Topic #: 1

An Infrastructure Manager is sizing the "Operations Reserve" for a VCF 9.0 Workload Domain. The developers plan to use vSAN Data Protection with highly aggressive snapshot schedules for their CI/CD pipelines (e.g., snapshots every 15 minutes, retaining 48 hours).
```
[SDDC Manager - Capacity Configuration]
Default vSAN Thresholds
Host Rebuild Reserve: 15% (Enabled)
Operations Reserve: 5% (Customized)
```
Historically, the manager lowered the Operations Reserve to 5% to grant more capacity to VMs.
How does the interaction of heavy snapshot activity and this customized Operations Reserve directly impact the cluster's stability and performance? (Select all that apply.)

A. If the Operations Reserve is exhausted by snapshot consolidation overhead, vSAN will throttle incoming VM write I/O to zero to prevent datastore corruption. B. Deep snapshot chains generate significant metadata overhead; when background snapshot deletions occur, they consume temporary staging space which can quickly exhaust a 5% Operations Reserve. C. The system will fail to delete older snapshots when the retention limit is reached if the Operations Reserve is full, causing the datastore to rapidly fill to 100%. D. vSAN ESA snapshots do not consume Operations Reserve space because they are log-structured B- tree pointers, making the 5% setting perfectly safe.
