- A
AWS Config
Why wrong: AWS Config evaluates resource configurations against desired policies and provides compliance history, but it does not automate patching. It can detect drift but cannot schedule or apply patches.
- B
Amazon Inspector
Why wrong: Amazon Inspector is a vulnerability management service that scans workloads for software vulnerabilities and network exposure. It identifies missing patches but does not apply them or provide a centralized patching dashboard.
- C
AWS Systems Manager Patch Manager
AWS Systems Manager Patch Manager automates the process of patching managed instances. With cross-account support via AWS Organizations and IAM roles, it allows you to define a single patch baseline, schedule patching across multiple accounts, and view aggregated compliance status in the Systems Manager console.
- D
AWS Trusted Advisor
Why wrong: AWS Trusted Advisor inspects your AWS environment and makes recommendations based on AWS best practices in categories like cost optimization, performance, security, and fault tolerance. It does not offer patch management or scheduling capabilities.
Quick Answer
The answer is AWS Systems Manager Patch Manager, which is the correct choice because it enables centralized patching across multiple AWS accounts by integrating with AWS Organizations, allowing a single operations team to define patch baselines, schedule patching, and view compliance status from a unified console without switching accounts. On the AWS Certified Cloud Practitioner CLF-C02 exam, this scenario tests your understanding of how Patch Manager, part of AWS Systems Manager, provides a single pane of glass for multi-account patch compliance management—a common trap is confusing it with AWS Config or Amazon Inspector, which focus on resource compliance and vulnerability scanning rather than automated patching. Remember that Patch Manager is the tool for applying patches, while Config tracks configuration changes; for exam success, think “Patch Manager patches, Config checks.” A helpful memory tip: “Patch Manager is your patch commander for multi-account compliance.”
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. 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. A key principle to apply: systems Manager Patch Manager automates patching of EC2 instances and on-premises servers.. 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 Organizations to manage multiple accounts. The operations team runs hundreds of Amazon EC2 instances across these accounts for various applications. The security team requires that all EC2 instances be patched with the latest security updates within 7 days of release. Currently, the operations team manually applies patches by logging into each account and using Systems Manager Patch Manager individually. The team wants to centralize patch compliance management so that a single operations team can define patch baselines, schedule patching, and view compliance status across all accounts from a single pane of glass, without needing to switch between accounts. Which AWS service or feature should the team use to meet these requirements?

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Amazon Inspector's vulnerability scanning with actual patch management, but Inspector only identifies vulnerabilities and does not apply patches, whereas Patch Manager is the service designed for centralized patching and compliance reporting.
Detailed technical explanation
How to think about this question
AWS Systems Manager Patch Manager uses SSM Agent on EC2 instances to execute patching operations based on patch baselines that define approved and rejected patches (e.g., by classification, severity, or product). When integrated with AWS Organizations, Patch Manager can use a delegated administrator account to manage patching across all member accounts via Systems Manager Quick Setup, which automatically configures the necessary IAM roles and targets, enabling a single operations team to schedule patching and view compliance from the Systems Manager console without switching accounts.
KKey Concepts to Remember
- Systems Manager Patch Manager automates patching of EC2 instances and on-premises servers.
- It integrates with AWS Organizations for cross-account patch baseline definition and compliance reporting.
- Patch Baselines define rules for approving or rejecting patches for different operating systems.
- Maintenance Windows can be used to schedule patching operations during specific times.
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.

Same concept, more angles
2 more ways this is tested on CLF-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company manages a fleet of hundreds of Amazon EC2 instances running across multiple AWS Regions. The company's security policy requires that all instances be patched with the latest security updates within 7 days of release. The operations team currently logs in to each instance manually to apply patches, which is time-consuming and error-prone. The team wants to automate the patching process, track compliance across all instances, and receive reports on patch status. The solution must not require any changes to the existing application code or the use of additional third-party software. Which AWS service should the operations team use to meet these requirements?
medium- A.AWS Config
- ✓ B.AWS Systems Manager
- C.Amazon Inspector
- D.AWS Trusted Advisor
Why B: AWS Systems Manager is the correct choice because it provides Patch Manager, a native capability that automates the patching of EC2 instances across multiple Regions without requiring any changes to application code or third-party software. It also integrates with Systems Manager Compliance to track patch status and generate reports, meeting all stated requirements.
Variation 2. A company runs a large fleet of Amazon EC2 instances across multiple environments (development, test, production). The security team requires a centralized, automated solution to apply operating system security patches on a regular schedule (e.g., every Tuesday at 2 AM). The solution must generate compliance reports showing which instances are patched and which are missing patches. The company wants a managed AWS service that works without requiring SSH or RDP access to the instances and does not require installing any custom agents. Which AWS service should the company use to meet these requirements?
medium- ✓ A.AWS Systems Manager Patch Manager
- B.AWS Config
- C.Amazon Inspector
- D.AWS OpsWorks
Why A: AWS Systems Manager Patch Manager is a managed service that automates the process of patching managed nodes with both security-related and other types of updates. It can be configured to run on a schedule (e.g., every Tuesday at 2 AM) using a Systems Manager maintenance window, and it generates compliance reports via Systems Manager Inventory and Compliance. Patch Manager works without requiring SSH or RDP access because it uses the AWS Systems Manager Agent (SSM Agent), which is pre-installed on many Amazon EC2 AMIs and can be installed without interactive logon, and it does not require custom agents beyond the SSM Agent itself.
