The answer is an Elastic Network Interface (ENI) with a primary private IP address. This is correct because an ENI is a virtual network card that persists independently of the EC2 instance’s lifecycle; when you attach an ENI with a primary private IP to an SAP application server, that IP remains static even after the instance is stopped and started. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this concept tests your understanding of network resilience for SAP workloads, where IP stability is critical for system replication and client communication. A common trap is confusing Elastic IPs (which are for public addressing) with private IP persistence, or assuming a secondary private IP on an ENI is equally stable—it is not, as secondary IPs can be reassigned. Remember the mnemonic: “ENI keeps the IP, Elastic IP keeps the public.”
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 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?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Elastic Network Interface (ENI) with a primary private IP
Option C is correct because an Elastic Network Interface (ENI) retains its private IP address and can be attached to an instance. Option A is wrong because Elastic IP is for public IPs. Option B is wrong because a secondary private IP on an ENI can change if not attached. Option D is wrong because a VPC endpoint is for connecting to AWS services, not for instance IPs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Related concept
Read the scenario before looking for a memorised answer.
✗
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
