- A
EBS Volume Queue Length
High queue length indicates I/O requests waiting, often a sign of storage bottleneck.
- B
EC2 SwapUsage (as custom metric)
Why wrong: Swap usage is important but not a standard CloudWatch metric; it requires custom monitoring.
- C
EC2 CPU Utilization
High CPU utilization can indicate performance issues.
- D
EC2 NetworkIn
Why wrong: NetworkIn is usually not a direct indicator of SAP health unless there is a network bottleneck.
- E
SAP work process usage (via SAP monitoring)
If work processes are fully utilized, the system cannot handle more requests.

PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is running an SAP NetWeaver system on AWS. The system includes a primary application server (PAS) and a dialog instance. The administrator wants to monitor the SAP system health using Amazon CloudWatch. Which THREE metrics should be monitored to proactively detect performance issues? (Choose THREE.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"primary"Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.

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
✓
EBS Volume Queue Length
EBS Volume Queue Length is a critical metric for SAP workloads because it directly indicates I/O latency. A high queue length means the storage subsystem cannot keep up with the SAP database or application server I/O requests, which can cause transaction delays and system hangs. Monitoring this metric allows proactive detection of storage bottlenecks before they impact SAP performance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often focus on CPU and memory metrics (like SwapUsage) because they are common in general server monitoring, but for SAP on AWS, storage I/O performance (EBS Queue Length) and SAP-specific work process utilization are more directly tied to application responsiveness and must be included alongside CPU Utilization.
Detailed technical explanation
How to think about this question
EBS Volume Queue Length represents the number of pending I/O requests waiting to be processed. For SAP NetWeaver, which relies on synchronous I/O for database transactions and log writes, a sustained queue length above 1 can indicate that the EBS volume's provisioned IOPS or throughput is insufficient. This metric is available in CloudWatch for EBS volumes attached to EC2 instances, and it is a leading indicator of storage performance degradation that can cause SAP work processes to wait, leading to dialog step timeouts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
Quick reference
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 |
