PAS-C01 Technology Practice Question
An administrator is setting up an SAP system on AWS and needs to assign a static private IP address to the SAP application server. Which AWS resource should be used to ensure the private IP address remains the same even after an instance stop/start?
⚠ Common exam trap
Watch out — candidates often confuse the persistence of an Elastic IP (which is a public IP) with the need for a static private IP, or they mistakenly think that secondary private IPs on the primary ENI survive instance stop/start, when in fact only an ENI as a standalone resource guarantees private IP persistence.

Correct answer & explanation
✓
Elastic Network Interface (ENI) with a primary private IP
An Elastic Network Interface (ENI) with a primary private IP address retains its private IP address across instance stop/start cycles because the ENI is a separate resource that persists independently of the instance lifecycle. When you attach an ENI to an SAP application server, the primary private IP (assigned from the VPC subnet) remains fixed even after the instance is stopped and started, ensuring consistent network addressing for SAP communication.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
VPC endpoint
Why it's wrong here
VPC endpoints are for private connectivity to AWS services, not for instance IPs.
- ✓
Elastic Network Interface (ENI) with a primary private IP
Why this is correct
An ENI retains its private IP address even when detached or attached to a different instance.
- ✗
Secondary private IP address on the primary network interface
Why it's wrong here
The secondary IP is tied to the ENI but can change if the ENI is recreated.
- ✗
Elastic IP address
Why it's wrong here
Elastic IP is a public IP address, not private.
