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.

An SAP system running on AWS uses a large memory-optimized instance (e.g., u-6tb1.metal). The system administrator notices that SAP workloads are occasionally hitting memory swap, causing performance degradation. The SAP application is configured to use SAP HANA. What is the most effective solution to address 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

✓

Enable HANA memory overcommit and use Kernel Same-page Merging (KSM) to reduce memory pressure

Option A is correct because enabling HANA memory overcommit allows the operating system to allocate more memory to processes than is physically available, while Kernel Same-page Merging (KSM) deduplicates identical memory pages, reducing overall memory consumption. This directly addresses the memory pressure causing swap without requiring additional hardware or disruptive changes to the SAP HANA configuration.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    Enable HANA memory overcommit and use Kernel Same-page Merging (KSM) to reduce memory pressure

    Why this is correct

    Reduces memory usage by sharing identical pages.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Configure HANA Large Pages to reduce memory fragmentation

    Why it's wrong here

    Large pages help CPU efficiency, not memory capacity.

  • ✗

    Set up a CloudWatch alarm to notify when memory usage exceeds 90%

    Why it's wrong here

    Monitoring alone does not solve the issue.

  • ✗

    Increase swap space on an attached EBS volume

    Why it's wrong here

    Swap on EBS is slower and increases latency.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the misconception that increasing swap space or using monitoring alone can resolve memory pressure, when the correct approach is to reduce actual memory consumption through techniques like KSM and overcommit.

Detailed technical explanation

How to think about this question

KSM works by scanning memory pages and merging identical pages into a single copy-on-write page, which is particularly effective in virtualized or HANA environments where multiple processes may load the same data. HANA memory overcommit leverages the Linux kernel's overcommit handling (vm.overcommit_memory=1) to allow the HANA process to allocate more virtual memory than physical RAM, relying on KSM to reduce actual physical memory usage. In real-world scenarios, this combination can reduce memory footprint by 10-30% without impacting HANA performance, but must be carefully tuned to avoid OOM killer intervention.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
