Exhibit
fio benchmark on the selected EC2 family: - Device: /dev/nvme1n1 - 4 KiB random read IOPS: 710,000 - Average latency: 0.18 ms - Sequential throughput: 2.8 GiB/s Workload notes: - Workers download source video files from S3 - They generate temporary frame extracts and intermediate artifacts locally - Final MP4 outputs are uploaded to S3 immediately after processing - If an instance terminates, the job is retried from the original source file
Based on the exhibit, which storage choice best matches the workload requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Use io2 EBS volumes because they provide the highest durable block storage performance.
io2 can be very fast, but the workload does not require durable local scratch data, so paying for persistence adds unnecessary cost and complexity.
B
Best answer
Use instance store NVMe for the temporary processing workspace.
Instance store fits a high-IOPS scratch workload where data can be lost safely and rebuilt from S3. The benchmark shows extremely low latency and very high random I/O performance, which is ideal for intermediate transcode files. Because the job can be retried from the source object, persistence is not needed on the local workspace.
C
Distractor review
Use Amazon EFS for the workspace so the temporary files survive instance replacement.
EFS is shared and persistent, but a network file system adds latency and is unnecessary when the workspace is disposable.
D
Distractor review
Use S3 as the working directory and read and write the intermediate files directly there.
S3 is object storage, not a low-latency filesystem for frequent read-modify-write scratch operations and temporary intermediates.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Use instance store NVMe for the temporary processing workspace. — The exhibit makes the key tradeoff explicit: the workspace is temporary, the job can be re-run from the source data, and the measured access pattern is extremely IOPS-intensive with very low latency. That points to instance store NVMe, which provides excellent local scratch performance at no durability cost. Durable block storage or shared network storage would add overhead without improving the job’s success criteria, because the important data already lives in S3. Why others are wrong: io2 is durable, but durability is not required for transient processing artifacts, so it is an overbuild. EFS is designed for shared persistent file access, but the workload does not need shared state and would incur extra network latency. S3 is durable and cheap, but it is object storage, not a suitable working filesystem for random temporary file access.
