PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP system uses a secondary IP address for the SAP application. After an instance reboot, the secondary IP address is no longer attached. What is the most likely cause?
⚠ Common exam trap
Candidates often confuse the behavior of Elastic IP addresses (which persist across stop/start if associated with an ENI) with secondary private IP addresses, which do not persist on the primary ENI after a stop/start cycle.

Correct answer & explanation
✓
The secondary IP address is not automatically re-attached after instance stop/start
When an EC2 instance is stopped and started, any secondary private IP addresses assigned to its primary Elastic Network Interface (ENI) are automatically released and not re-attached. The SAP application relies on this secondary IP address, so after a stop/start cycle the address is lost, requiring manual re-assignment or automation to restore it.
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 Elastic IP address was not associated with the instance
Why it's wrong here
Elastic IPs remain associated even after reboot.
- ✓
The secondary IP address is not automatically re-attached after instance stop/start
Why this is correct
Secondary IPs are not persistent across stop/start; they must be re-attached or use an ENI.
- ✗
The security group removed the IP address
Why it's wrong here
Security groups filter traffic but don't manage IP assignment.
- ✗
The Elastic Network Interface (ENI) was deleted
Why it's wrong here
ENIs persist unless explicitly deleted.
