Running Scripts on Tagged Instances with Run Command

This DOP-C02 practice question tests your understanding of configuration management and iac. 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.

A company uses AWS Systems Manager to manage a fleet of EC2 instances. They need to run a script on all instances that have a specific tag 'Environment:Development'. Which Systems Manager capability should be used?

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

✓

Run Command

Run Command is the correct capability because it allows you to remotely and securely execute scripts or commands on targeted EC2 instances using AWS Systems Manager. You can target instances by specifying tags, such as 'Environment:Development', and Run Command will execute the script on all matching instances without requiring SSH or RDP access.

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.

  • ✗

    Inventory

    Why it's wrong here

    Inventory collects metadata.

  • ✗

    Patch Manager

    Why it's wrong here

    Patch Manager is for patching.

  • ✓

    Run Command

    Why this is correct

    Run Command executes scripts on instances based on tags.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    State Manager

    Why it's wrong here

    State Manager is for maintaining desired state, not running scripts on demand.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is confusing Run Command with State Manager, as both can execute scripts, but State Manager is for recurring, state-enforcement tasks (using associations), not for immediate, tag-based ad-hoc execution.

Detailed technical explanation

How to think about this question

Run Command uses the SSM Agent on the instance to receive and execute commands via the Systems Manager service, leveraging AWS Identity and Access Management (IAM) roles for authentication and authorization. It supports both rate control (e.g., concurrency and error thresholds) and output logging to Amazon S3 or CloudWatch Logs, making it ideal for targeted, one-time operations like running a script on tagged instances. Under the hood, Run Command sends a command document (either pre-built or custom) to the SSM Agent, which executes it locally and reports status back to the service.

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.

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.
