PAS-C01 Operations and Maintenance Practice Question
An SAP administrator notices that the SAP HANA database on an EC2 instance is running out of memory frequently. The instance type is r5.4xlarge with 128 GiB of memory. Which action should the administrator take to resolve this 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
✓
Scale up to a larger instance type with more memory
Scaling up to a larger instance type, such as moving from an r5.4xlarge to an r5.8xlarge or higher, directly increases the available memory for SAP HANA, resolving the out-of-memory issue. Option A is incorrect because reducing the SAP HANA buffer cache size would degrade database performance and does not address the underlying memory shortage. Option B is incorrect because increasing swap space introduces disk-based paging, which can severely slow down HANA due to high latency, and is not a recommended solution. Option C is incorrect because enabling SAP HANA compression can reduce memory usage for data storage but does not add memory capacity; it is a tuning measure, not a direct fix for running out of memory.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduce the SAP HANA buffer cache size
Why it's wrong here
Reducing buffer cache can impact performance.
- ✗
Increase swap space on the instance
Why it's wrong here
Swap space can cause performance degradation.
- ✗
Enable SAP HANA compression
Why it's wrong here
Compression is already typically enabled; not a direct fix.
- ✓
Scale up to a larger instance type with more memory
Why this is correct
Larger instance provides more memory.
