The correct answer is Local NVMe instance store, along with Instance store and EBS io2 Block Express, because the application demands high-performance, low-latency storage attached to a single EC2 instance for caching, and these three options provide the necessary block-level performance with direct attachment. Instance store and Local NVMe instance store offer ultra-low latency by using physically attached disks on the host server, though they are ephemeral, while EBS io2 Block Express delivers persistent, high-durability block storage with sub-millisecond latency for critical cache data. On the SAP-C02 exam, this scenario tests your ability to distinguish between local ephemeral storage and network-attached persistent block storage, often appearing in migration questions where stateful applications rely on disk-based caching. A common trap is choosing shared solutions like EFS or S3, which introduce network latency and multi-instance access, violating the single-instance, low-latency requirement. Memory tip: for a single EC2 cache, think “local for speed, io2 for persistence”—if the cache can be rebuilt, use instance store; if it must survive reboots, choose io2 Block Express.
SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. 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.
A company is migrating a stateful application that uses local disks for caching to AWS. The application requires high-performance, low-latency storage that can be attached to a single EC2 instance. Which THREE AWS services or features should the company consider for the cache storage?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon EBS io2 Block Express
Option A (Instance store), Option C (EBS io2 Block Express), and Option E (Local NVMe instance store) are correct. Instance store provides high-performance local storage but ephemeral. EBS io2 Block Express provides high-performance persistent block storage. Local NVMe instance store is high-performance and local. Option B (EFS) is shared file system. Option D (S3) is object storage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Amazon EFS
Why it's wrong here
EFS is a shared file system, not block storage for a single instance.

✗
Amazon S3
Why it's wrong here
S3 is object storage with higher latency, not suitable for low-latency cache.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 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.
