PAS-C01 Design of SAP Workloads on AWS Practice Question

This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 runs SAP S/4HANA on AWS in a multi-AZ deployment. The SAP HANA database is 2 TB and uses EBS gp3 volumes. During a monthly patching cycle, the primary database fails over to the secondary, but the secondary takes over 30 minutes to come online. Which TWO changes would most likely reduce the failover time? (Choose two.)

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.
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.

A
Increase the provisioned IOPS and throughput on the EBS log volumes.
Higher log volume performance improves replication throughput.
B
Place the primary and secondary HANA servers in a cluster placement group.
Placement groups reduce network latency between nodes.
C
Use different EC2 instance types for primary and secondary to balance cost.
Why wrong: Asymmetric instances can cause performance mismatch.
D
Deploy all HANA nodes in the same Availability Zone to reduce network latency.
Why wrong: Same AZ removes HA benefit.
E
Enable EBS optimization on the secondary instance's EBS volumes.
Why wrong: EBS optimization is automatic on current gen instances.

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

✓

Increase the provisioned IOPS and throughput on the EBS log volumes.

Option A is correct because increasing the provisioned IOPS and throughput on the EBS log volumes accelerates the replay of redo logs during the takeover process. SAP HANA relies on log replay to bring the secondary database to a consistent state; higher IOPS/throughput reduces the time required to apply pending log entries, directly shortening failover duration.

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 network latency or instance placement (Options D and B) as the primary cause of slow failover, when in reality the bottleneck is the I/O performance of the log volumes during log replay.

Detailed technical explanation

How to think about this question

SAP HANA uses a log-based replication mechanism where the primary writes redo log entries to EBS log volumes, and the secondary replays them asynchronously or synchronously. During failover, the secondary must replay all unapplied log entries; the speed of this replay is directly limited by the IOPS and throughput of the log volumes. In practice, gp3 volumes can be provisioned with up to 16,000 IOPS and 1,000 MB/s throughput, and increasing these values can reduce failover from minutes to seconds in high-transaction environments.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
