This PAS-C01 practice question tests your understanding of migration. 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 financial services company is migrating its SAP HANA-based system from on-premises to AWS. The system is critical and must have a recovery point objective (RPO) of less than 1 minute and recovery time objective (RTO) of less than 15 minutes. The migration strategy is to use SAP HANA System Replication (HSR) in synchronous mode to an EC2 instance in the same region, then perform a takeover. However, during the test, the HSR replication latency is consistently above 100 ms, which prevents synchronous replication from working. The network between on-premises and AWS uses AWS Direct Connect with 1 Gbps bandwidth, and the physical distance is about 50 miles. Which action should the administrator take to achieve the RPO/RTO requirements?
Deploy the target EC2 instance in an AWS Local Zone closer to the on-premises data center.
Local Zones reduce physical distance and latency.
Use a Site-to-Site VPN instead of Direct Connect.
Why wrong: VPN typically adds latency.
Use asynchronous HSR mode instead of synchronous.
Why wrong: Asynchronous mode may not meet RPO of <1 minute.
Increase the Direct Connect bandwidth to 10 Gbps.
Why wrong: Bandwidth does not reduce 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
Deploy the target EC2 instance in an AWS Local Zone closer to the on-premises data center.
Synchronous HSR over long distance is challenging due to latency. Option A is correct because using AWS Local Zones reduces latency. Option B is wrong because increasing bandwidth does not reduce latency. Option C is wrong because asynchronous mode does not meet the RPO. Option D is wrong because VPN is slower and adds more latency.
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.
Deploy the target EC2 instance in an AWS Local Zone closer to the on-premises data center.
Why this is correct
Local Zones reduce physical distance and latency.

Use a Site-to-Site VPN instead of Direct Connect.
Why it's wrong here
VPN typically adds latency.
Use asynchronous HSR mode instead of synchronous.
Why it's wrong here
Asynchronous mode may not meet RPO of <1 minute.
Increase the Direct Connect bandwidth to 10 Gbps.
Why it's wrong here
Bandwidth does not reduce latency.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
