This PAS-C01 practice question tests your understanding of migration. 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.
During the migration of an SAP ERP system to AWS, the SAP application team reports that after migrating the database to Amazon RDS for SAP HANA, batch jobs that previously ran in 2 hours now take 5 hours. The system uses AWS Direct Connect with adequate bandwidth. Which action is most likely to resolve this performance issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Enable Multi-AZ deployment for RDS.
Why wrong: Multi-AZ is for high availability, not performance.
Increase the RDS instance size and storage IOPS.
Larger instance provides more CPU and memory for HANA.
Reduce the automated backup retention period.
Why wrong: Backup retention does not affect runtime performance.
Increase the Direct Connect bandwidth.
Why wrong: Bandwidth is not the bottleneck if batch jobs are compute-bound.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Increase the RDS instance size and storage IOPS.
SAP HANA on RDS uses a single-AZ deployment by default; enabling Multi-AZ adds a standby but does not improve performance. However, the most impactful change is increasing the instance size (compute and memory) to match the on-premises capacity. Option A is wrong because RDS Multi-AZ does not improve performance. Option B is wrong because the bandwidth is already adequate. Option D is wrong because reducing backup retention does not affect runtime performance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Enable Multi-AZ deployment for RDS.
Why it's wrong here
Multi-AZ is for high availability, not performance.
Increase the RDS instance size and storage IOPS.
Why this is correct
Larger instance provides more CPU and memory for HANA.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
Reduce the automated backup retention period.
Why it's wrong here
Backup retention does not affect runtime performance.
Increase the Direct Connect bandwidth.
Why it's wrong here
Bandwidth is not the bottleneck if batch jobs are compute-bound.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
