The answer is to migrate to io1 or io2 EBS volumes with provisioned IOPS. This is correct because SAP ASE write performance on AWS EBS is heavily dependent on consistent, low-latency I/O, and io1/io2 volumes deliver guaranteed IOPS that eliminate the burst-bucket limitations and throughput variability inherent in gp2 volumes, which cause write latency spikes under sustained load. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of how database workloads require predictable block storage performance, and a common trap is choosing gp3—while it offers baseline performance, it still lacks the dedicated IOPS provisioning of io1/io2 for write-heavy SAP ASE transactions. Remember the memory tip: “For SAP writes that never sleep, choose provisioned IOPS deep.”
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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 application running on AWS is experiencing high latency for database write operations. The system uses SAP ASE on Amazon EC2 with gp2 EBS volumes. Which change is most likely to improve write performance?
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Migrate to io1/io2 EBS volumes with provisioned IOPS.
Option B is correct because io1/io2 volumes provide consistent IOPS performance suitable for database workloads. Option A is wrong because gp3 may still not guarantee low latency writes. Option C is wrong because instance store is ephemeral and data is lost on stop/termination. Option D is wrong because S3 is object storage, not block storage for database.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Move database write logs to Amazon S3 for better throughput.
Why it's wrong here
S3 is object storage with higher latency; not suitable for database write logs.
✓
Migrate to io1/io2 EBS volumes with provisioned IOPS.
Why this is correct
Provisioned IOPS volumes are designed for consistent, low-latency database workloads.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Migrate to gp3 EBS volumes with higher baseline performance.
Why it's wrong here
gp3 improves but does not guarantee provisioned IOPS for bursty writes.
✗
Use instance store volumes for database data files.
Why it's wrong here
Instance store is ephemeral and not durable; not suitable for database persistence.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Migrate to io1/io2 EBS volumes with provisioned IOPS. — Option B is correct because io1/io2 volumes provide consistent IOPS performance suitable for database workloads. Option A is wrong because gp3 may still not guarantee low latency writes. Option C is wrong because instance store is ephemeral and data is lost on stop/termination. Option D is wrong because S3 is object storage, not block storage for database.
