SOA-C02 Practice Question: SSM Run Command for executing scripts across a…
This SOA-C02 practice question tests your understanding of ssm run command for executing scripts across a…. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. A key principle to apply: sSM Run Command. 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 security policy prohibits opening SSH port 22 on any EC2 instance. The operations team needs to run a shell script on 150 Linux instances to collect configuration inventory data. The script output must be captured for review. How should the team execute the script?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Create a bastion host with SSH access and use a for loop to SSH into each instance and run the script
The security policy explicitly prohibits SSH. A bastion host would require port 22 to be open on all 150 instances to the bastion's IP — this directly contradicts the policy.
B
Distractor review
Use EC2 Instance Connect to establish a temporary SSH session for each instance and run the script
EC2 Instance Connect pushes a temporary SSH public key to the instance metadata and then opens an SSH connection. It still uses SSH and requires port 22 to be open in the security group — violating the policy.
C
Distractor review
Terminate all instances and re-launch them from a new AMI that includes the configuration inventory already baked in
Terminating and replacing instances to collect inventory data is destructively disproportionate. Run Command collects the data from running instances with no disruption.
D
Best answer
Use SSM Run Command with the AWS-RunShellScript document targeting all 150 instances; send output to an S3 bucket
Run Command invocations use the SSM Agent's existing outbound HTTPS connection (port 443) — no inbound rule changes are needed. The command output for each instance is stored separately in S3, allowing the team to review per-instance results. Commands can target instances by tag (e.g., Environment=production) to avoid listing all 150 instance IDs manually.
Common exam trap
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.
Technical deep dive
How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- SSM Run Command
- AWS-RunShellScript
- managed instances
- no SSH required
- command output to S3
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.

Question 1
A company uses Amazon CloudFront to deliver content to a global audience. The origin is an Application Load Balancer in us-east-1. The SysOps administrator wants to reduce costs by minimizing the number of requests that reach the origin server. Which action should the administrator take?
Question 2
A company runs a batch processing application on Amazon EC2 that runs for 2 hours every night. The workload can tolerate interruptions. Which EC2 purchasing option provides the lowest cost for this use case?
Question 3
A SysOps administrator needs to monitor the CPU utilization of an Amazon RDS DB instance and receive an alarm when CPU utilization exceeds 80% for 5 consecutive minutes. Which AWS service should be used to create this alarm?
Question 4
A company runs a critical web application on Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). The application uses session stickiness (sticky sessions) to maintain user sessions. The SysOps administrator notices that when instances are replaced during a scale-in or failure event, users lose their session data. The administrator needs to preserve session data across instance failures without losing stickiness benefits. What should the administrator do?
Question 5
A company runs a production web application on a single Amazon EC2 instance. The application experiences a predictable and steady workload 24/7. The SysOps administrator wants to minimize compute costs for this instance while ensuring it remains available during the expected workload. Which EC2 purchasing option should the administrator use?
Question 6
A company has a VPC with public and private subnets. The private subnets host application servers that need to make outbound HTTPS connections to the internet. The SysOps administrator must implement a solution that provides outbound internet connectivity while preventing inbound connections from the internet. Additionally, the solution must allow the company to control which domains the application servers can access. Which solution should the administrator implement?

FAQ
Questions learners often ask
What does this SOA-C02 question test?
SSM Run Command
What is the correct answer to this question?
The correct answer is: Use SSM Run Command with the AWS-RunShellScript document targeting all 150 instances; send output to an S3 bucket — AWS Systems Manager Run Command uses the SSM Agent already installed on the instances to execute commands without requiring SSH access or open inbound ports. The AWS-RunShellScript document accepts a shell script body. Instances are targeted by tag, resource group, or list. Command output (stdout/stderr) can be written to an S3 bucket or CloudWatch Logs for review. No security group changes are required — SSM Agent uses the instance's outbound HTTPS connection to the SSM service endpoint.
What should I do if I get this SOA-C02 question wrong?
