PAS-C01 Technology Practice Question
A company is planning to migrate its SAP HANA database to AWS. The database size is 3 TB, and they need high I/O performance with low latency. The SAP workload is critical and requires high availability. Which AWS storage solution should they choose for the HANA data volume?
Answer choices
Why each option matters
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 volumes.
AWS strongly recommends using Amazon EBS io2 Block Express volumes for SAP HANA data volumes due to their high performance, low latency, and high durability, which meet SAP's critical workload and high availability requirements. Option A (EBS gp3) is cost-effective but may not provide the consistent low latency required for SAP HANA. Option B (EC2 Instance Store) offers low latency but is ephemeral and does not provide data persistence, making it unsuitable for database data. Option C (EFS with Provisioned Throughput) is a file system, not block storage, and is not supported for SAP HANA data volumes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon EBS gp3 volumes.
Why it's wrong here
gp3 volumes are suitable for many workloads but may not meet the stringent latency requirements of SAP HANA under heavy load.
- ✗
EC2 Instance Store volumes.
Why it's wrong here
Instance Store is ephemeral and data is lost on instance stop/termination, so it is not suitable for persistent HANA data.
- ✗
Amazon EFS with Provisioned Throughput.
Why it's wrong here
EFS is a file system, not block storage, and is not recommended for HANA data volumes.
- ✓
Amazon EBS io2 Block Express volumes.
Why this is correct
io2 Block Express offers high performance, low latency, and high durability, making it ideal for SAP HANA.
