PAS-C01 Migration Practice Question
A large enterprise is migrating its SAP S/4HANA system to AWS. The system includes a production SAP HANA database (4 TB) and a development SAP HANA database (1 TB). The migration strategy is to use SAP HANA System Replication (HSR) for both databases to EC2 instances in the same AWS region. The company has a compliance requirement that the production database must be in a different AWS account than the development database. The network between on-premises and AWS uses AWS Direct Connect with 10 Gbps bandwidth. During the test migration, the HSR replication for the development database works, but the production database fails to establish replication. The error log shows: "HSR connection timed out." The security groups and network ACLs for the production target EC2 instance allow inbound traffic on port 30101 from the on-premises source IP. What is the most likely cause of the failure?
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
✓
The production target EC2 instance is in a different AWS account, and there is no VPC peering or Transit Gateway between the accounts to allow connectivity.
HSR requires communication between the source and target HANA instances. If the target is in a different account, VPC peering or Transit Gateway is needed for cross-account connectivity. Option A is correct because cross-account communication requires VPC peering or Transit Gateway. Option B is wrong because the port is correct. Option C is wrong because HSR does not use port 443. Option D is wrong because the source is on-premises, not in another AWS account.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The production target EC2 instance is in a different AWS account, and there is no VPC peering or Transit Gateway between the accounts to allow connectivity.
Why this is correct
Cross-account communication needs VPC peering or Transit Gateway.
- ✗
The production source HANA instance is not configured to replicate to a different AWS account.
Why it's wrong here
HSR can replicate across accounts if networking allows.
- ✗
The production target EC2 instance is using the wrong port for HSR.
Why it's wrong here
Port 30101 is correct for HSR.
- ✗
The security group on the production target EC2 instance does not allow inbound traffic on port 443.
Why it's wrong here
HSR uses port 30101, not 443.
