- A
Use a Dedicated Host and configure two separate virtual servers using VMware on AWS.
Why wrong: Option A is incorrect because a Dedicated Host is not required; the 'same host' capability works on any EC2 instance. VMware on AWS is not needed.
- B
Configure two network interfaces (ENIs) on the instance, one for ASCS and one for ERS.
Why wrong: Option B is incorrect because two ENIs are not required; a single ENI suffices for both ASCS and ERS.
- C
Assign multiple private IP addresses to the same ENI and configure ASCS and ERS to bind to different IPs.
Why wrong: Option C is incorrect because assigning multiple private IPs to the same ENI is possible but not necessary; SAP's built-in 'same host' feature handles the binding without manual IP assignment.
- D
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, allowing both instances to run simultaneously on the same EC2 instance without requiring separate virtual servers or complex networking.
PAS-C01 SAP ASCS/ERS same host configuration 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. A key principle to apply: sAP ASCS/ERS same host configuration. 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 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, allowing both instances to run simultaneously on the same EC2 instance without requiring separate virtual servers or complex networking. Option A is incorrect because a Dedicated Host is not needed; the 'same host' capability works on any EC2 instance. Option B is incorrect because two ENIs are not required; a single ENI suffices. Option C is incorrect because although assigning multiple private IPs is possible, it is not the standard or necessary configuration; SAP's built-in 'same host' feature handles the binding without manual IP assignment.

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.

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
SAP ASCS/ERS same host configuration
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.
