PAS-C01 Migration Practice Question
A technology company is migrating its SAP Business Warehouse (BW) system to AWS. The system includes an SAP HANA database (2 TB) and multiple application servers. The migration plan is to use SAP HANA System Replication (HSR) for the database and AWS Application Migration Service (MGN) for the application servers. The network connection is AWS Direct Connect with 1 Gbps bandwidth. During a test migration, the HSR replication is working, but the MGN replication for one of the application servers is failing with an error: "The agent cannot communicate with the MGN service endpoint." The source server is a Windows Server 2016 machine. The administrator has verified that the source server has internet connectivity. Which action is most likely to resolve the issue?
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
✓
Configure an HTTP proxy on the source server to route traffic through the corporate proxy.
The error indicates the MGN agent cannot reach the service endpoint. Since the source server has internet connectivity, the issue is likely that outbound traffic to the MGN endpoint is blocked by a corporate proxy or firewall. Configuring an HTTP proxy on the source server (option B) allows the agent to route traffic through the corporate proxy, which is a common requirement in enterprise environments. Option C (creating a VPC endpoint) is not applicable because the source server is on-premises, not in a VPC. Option A (reinstalling the agent) does not address the connectivity issue. Option D (changing OS) is irrelevant.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reinstall the MGN agent on the source server.
Why it's wrong here
Reinstalling the MGN agent does not resolve connectivity issues between the agent and the MGN service endpoint. The error persists because the agent cannot communicate, which is not fixed by reinstallation.
- ✓
Configure an HTTP proxy on the source server to route traffic through the corporate proxy.
Why this is correct
Configuring an HTTP proxy on the source server allows the MGN agent to route traffic through the corporate proxy, which is likely required to reach the MGN service endpoint. This directly addresses the communication failure while maintaining internet connectivity.
- ✗
Create a VPC endpoint for AWS Application Migration Service in the source VPC.
Why it's wrong here
Creating a VPC endpoint for AWS Application Migration Service is not applicable because the source server is on-premises, not within an AWS VPC. VPC endpoints provide private connectivity within AWS, not from on-premises networks.
- ✗
Change the source server's OS to Linux.
Why it's wrong here
Changing the source server's operating system from Windows to Linux does not resolve the communication issue. The error is network-related, not OS-dependent.
