PAS-C01 Operations and Maintenance Practice Question
An SAP system on AWS is experiencing high latency. Which THREE metrics should be examined in Amazon CloudWatch to diagnose the issue?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
NetworkIn/NetworkOut
Options A, D, and E are correct. A (NetworkIn/NetworkOut) can indicate network bandwidth saturation, which causes latency. D (CPUUtilization) can indicate CPU bottleneck, leading to processing delays. E (EBS VolumeQueueLength) indicates storage I/O wait, a common cause of latency in SAP systems. B (DiskReadBytes) alone is less informative without queue length; high read/write bytes don't necessarily indicate latency. C (StatusCheckFailed) is for instance health, not performance latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
NetworkIn/NetworkOut
Why this is correct
Network metrics can reveal congestion.
- ✗
DiskReadBytes
Why it's wrong here
Disk reads alone may not indicate latency; queue length is better.
- ✗
StatusCheckFailed
Why it's wrong here
Status checks indicate hardware/software issues, not directly latency.
- ✓
CPUUtilization
Why this is correct
High CPU can cause application latency.
- ✓
EBS VolumeQueueLength
Why this is correct
Queue length indicates I/O wait, a common cause of latency.

AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
