PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP system administrator needs to monitor the memory usage of SAP HANA on AWS. Which CloudWatch metric or log should be used to track HANA memory consumption?
⚠ Common exam trap
Watch out — candidates often confuse OS-level memory metrics (which require the CloudWatch Agent) with HANA-specific memory metrics, not realizing that HANA’s internal memory management (e.g., column store, row store, heap) is only accessible through its SQL views, not through standard OS monitoring tools.

Correct answer & explanation
✓
SAP HANA CloudWatch integration via SQL queries
SAP HANA exposes memory consumption metrics via built-in SQL views (e.g., M_HOST_MEMORY, M_MEMORY), and the SAP HANA CloudWatch integration uses a dedicated AWS Lambda function to execute these SQL queries and push the results as custom CloudWatch metrics. This is the only option that directly captures HANA-specific memory usage, such as allocation limit, used memory, and heap memory, rather than generic OS-level metrics.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
CloudWatch Logs from HANA trace files
Why it's wrong here
Trace files are not structured metrics.
- ✓
SAP HANA CloudWatch integration via SQL queries
Why this is correct
HANA exposes memory metrics via SQL, which can be sent to CloudWatch.
- ✗
EC2 instance-level memory metrics
Why it's wrong here
EC2 metrics show host memory, not HANA usage.
- ✗
AWS CloudWatch Agent for OS metrics
Why it's wrong here
OS metrics do not show HANA-specific memory.
