This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 on AWS is experiencing high read latency from the SAP HANA database. The system uses Provisioned IOPS EBS volumes. Which action would most likely improve read latency?
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.
Change the EBS volume type to gp2.
Why wrong: gp2 has lower performance than io1/io2.
Disable write caching on the EBS volumes.
Why wrong: Write caching does not affect read latency.
Move the HANA data to instance store volumes.
Why wrong: Instance store is ephemeral and unreliable for databases.
Increase the provisioned IOPS on the EBS volumes.
More IOPS can reduce read latency.
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 provisioned IOPS on the EBS volumes.
Increasing the provisioned IOPS on the EBS volumes directly addresses high read latency by raising the I/O performance ceiling for the SAP HANA database. Since the system already uses Provisioned IOPS (io1/io2) volumes, higher IOPS reduces queue depth and read latency under heavy workloads, which is a common requirement for SAP HANA.
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.
Change the EBS volume type to gp2.
Why it's wrong here
gp2 has lower performance than io1/io2.
Disable write caching on the EBS volumes.
Why it's wrong here
Write caching does not affect read latency.
Move the HANA data to instance store volumes.
Why it's wrong here
Instance store is ephemeral and unreliable for databases.
Increase the provisioned IOPS on the EBS volumes.
Why this is correct
More IOPS can reduce read latency.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Common exam traps
The trap here is that candidates may think increasing IOPS always helps, but the key nuance is that the system already uses Provisioned IOPS, so the correct action is to increase the provisioned IOPS value, not change volume types or rely on ephemeral storage.
Detailed technical explanation
Provisioned IOPS EBS volumes (io1/io2) allow you to specify a consistent IOPS rate, independent of volume size, which is critical for SAP HANA’s real-time analytics. High read latency often stems from IOPS exhaustion, where the volume’s queue depth increases; increasing provisioned IOPS reduces queue depth and latency. In contrast, gp2 volumes rely on a credit-based burst model, which can deplete under sustained loads, causing throttling and higher latency.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
