- A
Adjust the S3 bucket policy to allow access from the new VPC.
Why wrong: 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.
- B
Update the Amazon Route 53 DNS records for the SAP application and database servers.
When instances are migrated to a new VPC, their private IP addresses may change; DNS records must be updated to maintain name resolution.
- C
Modify the SAProuter configuration (e.g., saprouttab) to use the new IP address or hostname of the SAProuter instance.
SAProuter connections rely on the IP address/hostname of the SAProuter instance; if it changes, the configuration must be updated.
- D
Recreate IAM roles for the SAP application servers.
Why wrong: IAM roles are global and not tied to a specific VPC; they do not need to be recreated.
- E
Update security group rules and network ACLs to allow SAP traffic in the new VPC.
Security groups and network ACLs are VPC-specific and must be configured to permit required SAP ports and protocols.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
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.
Option B is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
SAProuter uses the saprouttab file to define allowed routes and destination IPs/hostnames; during a VPC migration, the SAProuter instance's IP changes, requiring an update to saprouttab and the SAProuter service restart. Route 53 DNS records must be updated to reflect the new VPC's CIDR ranges and private IPs, as SAP applications often use hostnames for internal communication, and stale DNS entries cause resolution failures. Security group and NACL rules must be reconfigured to permit SAP-specific ports (e.g., 3299 for SAProuter, 3200 for SAP GUI, 36xx for message server) in the new VPC's subnet boundaries.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
