- A
Use a Dedicated Host and configure two separate virtual servers using VMware on AWS.
Why wrong: VMware on AWS is unnecessary complexity; SAP supports running both instances on the same OS.
- B
Configure two network interfaces (ENIs) on the instance, one for ASCS and one for ERS.
Why wrong: Multiple ENIs are not required; a single ENI can handle both services via different ports.
- C
Assign multiple private IP addresses to the same ENI and configure ASCS and ERS to bind to different IPs.
Why wrong: Multiple IPs on one ENI are possible but not the standard approach for same-host ASCS/ERS; the roles typically use different ports.
- D
Install both ASCS and ERS on the same EC2 instance using the SAP NetWeaver 7.4 or later 'same host' capability.
Starting with NetWeaver 7.4, SAP supports running ASCS and ERS on the same physical host, which simplifies the architecture.
Quick Answer
The correct answer is to install both ASCS and ERS on the same EC2 instance using the SAP NetWeaver 7.4 or later 'same host' capability. This works because starting with NetWeaver 7.4, SAP introduced native support for running both the ASCS and ERS instances on a single host, allowing Pacemaker to manage them as clustered resources without requiring separate physical servers or complex networking workarounds. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of SAP’s built-in high-availability features versus AWS-specific configurations like multiple ENIs or dedicated tenancy—common traps that distract from the simpler, SAP-native solution. A key memory tip is to remember that "7.4 is the door" for same-host ASCS and ERS, meaning any version 7.4 or later unlocks this capability natively, so avoid overcomplicating the answer with unnecessary AWS networking tricks.
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.
A company is migrating its SAP ERP system to AWS and needs to maintain high availability. The SAP Central Services (ASCS) and ERS instances are currently on two separate physical servers. The company wants to use a single EC2 instance for both roles with Pacemaker clustering. Which configuration ensures that both instances can run simultaneously on the same host?
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
Install both ASCS and ERS on the same EC2 instance using the SAP NetWeaver 7.4 or later 'same host' capability.
Option D is correct because SAP NetWeaver 7.4 and later support the 'same host' configuration for ASCS and ERS. Option A is wrong because multi-IP configuration is not typically required. Option B is wrong because dedicated tenancy is not necessary. Option C is wrong because using a single ENI with multiple IPs is not standard.
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
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
