Quick Answer
The answer is AWS Systems Manager Run Command, as it enables low-latency execution of forensic scripts directly on EC2 instances via the SSM Agent while securely storing command output in Amazon S3 or CloudWatch Logs. This capability is ideal for incident response because it avoids the overhead of interactive sessions or complex automation, allowing rapid, auditable data collection without persistent access. On the AWS Certified Security Specialty SCS-C02 exam, this scenario tests your understanding of how Run Command differs from Session Manager (which is interactive) and State Manager (which is for scheduled maintenance). A common trap is choosing Session Manager for its shell access, but the question emphasizes minimal latency and secure result storage, not interactive control. Remember the tip: “Run Command runs and stores; Session Manager shells and explores.”
This SCS-C02 practice question tests your understanding of threat detection and incident response. 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's incident response team is using AWS Systems Manager to run commands on EC2 instances for forensic analysis. The team needs to ensure that the commands are run with minimal latency and that the results are stored securely. Which Systems Manager capability should the team use?
AWS Systems Manager Automation
Why wrong: Automation is for multi-step workflows.
AWS Systems Manager Session Manager
Why wrong: Session Manager provides interactive shell access, not command execution with stored results.
AWS Systems Manager Patch Manager
Why wrong: Patch Manager is for patching, not forensic commands.
AWS Systems Manager Run Command
Run Command executes commands with low latency and can store output in S3.

Correct answer & explanation
AWS Systems Manager Run Command
AWS Systems Manager Run Command is the correct capability because it allows the incident response team to execute commands on EC2 instances with minimal latency by using the SSM Agent to run scripts or commands directly, and it can store command output in Amazon S3 or CloudWatch Logs for secure, durable storage. This meets the requirement for low-latency execution and secure result storage without requiring interactive sessions or complex automation workflows.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Systems Manager Automation
Why it's wrong here
Automation is for multi-step workflows.
AWS Systems Manager Session Manager
Why it's wrong here
Session Manager provides interactive shell access, not command execution with stored results.
AWS Systems Manager Patch Manager
Why it's wrong here
Patch Manager is for patching, not forensic commands.
AWS Systems Manager Run Command
Why this is correct
Run Command executes commands with low latency and can store output in S3.

Common exam traps
The trap here is that candidates often confuse Session Manager (interactive access) with Run Command (non-interactive execution), assuming that 'minimal latency' implies a live session, but Run Command is actually faster for scripted tasks because it avoids session setup overhead and can target multiple instances in parallel.
Trap categories for this question
Command / output trap
Session Manager provides interactive shell access, not command execution with stored results.
Detailed technical explanation
Run Command uses the SSM Agent (which runs on the instance) to receive commands via the Systems Manager service endpoint over HTTPS (port 443), enabling near-instant execution without requiring SSH or RDP. Output can be encrypted at rest in S3 using SSE-S3 or SSE-KMS, and the command execution is logged in AWS CloudTrail for auditability. In a forensic scenario, this allows the team to run memory acquisition or disk analysis scripts across hundreds of instances simultaneously with sub-second latency.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Variation 1. A company is designing an incident response plan for AWS. The plan must include the ability to collect forensic data from EC2 instances without requiring SSH key pairs. Which TWO AWS services can be used to acquire forensic data from EC2 instances without remote access? (Choose 2.)
easyWhy A: AWS Systems Manager Run Command allows you to run scripts or commands on EC2 instances via the SSM Agent, without requiring SSH keys or direct network access. This enables forensic data collection (e.g., memory dumps, log files) by executing commands remotely through the AWS Systems Manager service, using IAM roles for authentication.
