Quick Answer
The answer is an EC2 instance with high network bandwidth and Enhanced Networking. This is correct because SAP HANA System Replication initial sync requires massive network throughput to transfer the full 5 TB database within the 8-hour window; without sufficient bandwidth, the sync will exceed the time limit regardless of storage performance. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that HSR initial sync is a network-bound operation, not a storage-bound one, and the common trap is choosing EBS gp3 volumes, which are secondary to network capacity. Remember that Enhanced Networking with ENA can deliver up to 100 Gbps, making it the bottleneck to solve first. Memory tip: think “sync speed = network speed” for HSR initial sync.
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 company is migrating an SAP HANA database to AWS using the SAP HANA System Replication (HSR) with asynchronous mode. The database size is 5 TB. The migration must be completed within 8 hours. Which AWS resource is most critical to ensure the initial data synchronization completes within the time window?
EC2 instance with high network bandwidth and Enhanced Networking
HSR initial sync is network-bound; high bandwidth instances reduce sync time.
EBS snapshots for the initial data copy
Why wrong: HSR uses log shipping, not snapshots.
EBS gp3 volumes with sufficient IOPS
Why wrong: Storage performance is important but the bottleneck is network bandwidth for sync.
Amazon S3 multipart upload for initial data
Why wrong: S3 is not used in HSR.

Correct answer & explanation
EC2 instance with high network bandwidth and Enhanced Networking
Option B is correct. The initial sync requires high network throughput; using an instance with high network bandwidth (e.g., ENA, up to 100 Gbps) is critical. Option A (EBS gp3 volume) is important but secondary to network. Option C (EBS snapshots) are not used in HSR. Option D (S3 multipart upload) is irrelevant.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

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.
