The correct prerequisite is that the SSM Agent must be installed and running on each EC2 instance. This agent acts as the bridge between the instance and the AWS Systems Manager service, enabling secure command execution, patching workflows, and inventory collection. Without the agent, Systems Manager cannot initiate SAP patching tasks or communicate with the instance at all. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this concept tests your understanding of foundational Systems Manager operations, often appearing as a distractor where candidates assume IAM roles alone are sufficient—roles are necessary, but the agent is the non-negotiable first step. A common trap is forgetting that custom or imported SAP AMIs do not include the agent pre-installed, unlike standard Amazon Linux or Windows AMIs. Memory tip: Think of the SSM Agent as the “key in the ignition”—without it, no patching engine can start.
PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 wants to use AWS Systems Manager to automate patching of SAP application servers. What is a prerequisite for Systems Manager to manage these EC2 instances?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Install the SSM Agent on the EC2 instances.
AWS Systems Manager requires the SSM Agent to be installed and running on EC2 instances to enable communication with the Systems Manager service for patching and other management tasks. Without the agent, Systems Manager cannot send commands, initiate patching workflows, or gather inventory data from the instances. The SSM Agent is pre-installed on many Amazon Linux and Windows AMIs but must be manually installed on custom or imported images.
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.
An instance profile with appropriate permissions is needed, but not separate roles per instance.
✓
Install the SSM Agent on the EC2 instances.
Why this is correct
SSM Agent is required for Systems Manager to communicate with instances.
Related concept
Read the scenario before looking for a memorised answer.
✗
Ensure the instances have public IP addresses.
Why it's wrong here
Systems Manager can work via VPC endpoints without public IPs.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume SSH or public IP addresses are required for remote management, but Systems Manager is designed to work without them, relying solely on the SSM Agent and IAM permissions over HTTPS.
Detailed technical explanation
How to think about this question
The SSM Agent runs as a system service (e.g., amazon-ssm-agent on Linux) and establishes a bidirectional WebSocket connection to the Systems Manager service using AWS Identity and Access Management (IAM) credentials from the instance profile. For patching, Systems Manager uses the AWS-RunPatchBaseline document, which the agent executes locally to apply patches based on the configured patch baseline. In environments with strict network controls, you can use AWS Systems Manager VPC endpoints (interface endpoints) to keep traffic within the VPC, eliminating the need for internet access or public IPs.

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
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.
