PAS-C01 Migration Practice Question
An organization is migrating their SAP ERP system to AWS and needs to set up a disaster recovery (DR) site in another AWS region. They want to use AWS Elastic Disaster Recovery (DRS) for SAP HANA. The source HANA system is running on-premises on a physical server. They have installed the DRS agent on the source server. During the initial replication, they notice that the data transfer is very slow. What should they do to improve replication speed?
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
✓
Increase the number of concurrent data streams in the DRS agent configuration
AWS Elastic Disaster Recovery (DRS) allows configuring multiple concurrent data streams to increase network throughput and improve replication speed. Option A is incorrect because DRS already uses asynchronous replication by default; switching to asynchronous does not change the current mode. Option B is incorrect because Amazon RDS for HANA is a managed database service, not a DR target for DRS; DRS replicates to EC2 instances. Option C is incorrect because the staging area subnet size affects storage capacity, not replication speed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Switch to asynchronous replication mode
Why it's wrong here
Asynchronous replication may not be suitable for DR.
- ✗
Use Amazon RDS for HANA as the DR target instead of EC2
Why it's wrong here
RDS does not support HANA DR replication via DRS.
- ✗
Increase the size of the staging area subnet
Why it's wrong here
Staging area size does not affect replication speed.
- ✓
Increase the number of concurrent data streams in the DRS agent configuration
Why this is correct
More streams can utilize available bandwidth better.
