PAS-C01 Technology Practice Question
An SAP application on AWS needs to be migrated to a new virtual private cloud (VPC). The SAP system uses SAProuter to connect to SAP support. Which THREE components must be updated or re-configured during the migration to ensure uninterrupted connectivity?
⚠ Common exam trap
The trap here is that candidates may overlook DNS updates (Option B) as a critical step, assuming IP addresses are static, or mistakenly think IAM roles (Option D) or S3 policies (Option A) are relevant to network-level connectivity during a VPC migration.
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
✓
Update the Amazon Route 53 DNS records for the SAP application and database servers.
Updating Amazon Route 53 DNS records ensures that the SAP application and database servers can be reached using their new private or public IP addresses in the new VPC. Without this update, clients and SAP support connections via SAProuter would fail due to DNS resolution pointing to the old VPC's IPs, causing connectivity interruptions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Adjust the S3 bucket policy to allow access from the new VPC.
Why it's wrong here
S3 bucket policies use IAM principals and VPC conditions, but if the S3 bucket remains the same, the policy does not need to change just because the VPC changes.
- ✓
Update the Amazon Route 53 DNS records for the SAP application and database servers.
Why this is correct
When instances are migrated to a new VPC, their private IP addresses may change; DNS records must be updated to maintain name resolution.
- ✓
Modify the SAProuter configuration (e.g., saprouttab) to use the new IP address or hostname of the SAProuter instance.
Why this is correct
SAProuter connections rely on the IP address/hostname of the SAProuter instance; if it changes, the configuration must be updated.
- ✗
Recreate IAM roles for the SAP application servers.
Why it's wrong here
IAM roles are global and not tied to a specific VPC; they do not need to be recreated.
- ✓
Update security group rules and network ACLs to allow SAP traffic in the new VPC.
Why this is correct
Security groups and network ACLs are VPC-specific and must be configured to permit required SAP ports and protocols.
