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?
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
AWS Config
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
Distractor review
Amazon Inspector
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
Best answer
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
Distractor review
AWS Trusted Advisor
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.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A developer needs to launch a test server for a new application prototype. The developer logs into the AWS Management Console, selects an Amazon EC2 instance type, configures the security group, and starts the instance. The instance is running within two minutes, and the developer did not need to submit a formal request to the company's IT procurement team or wait for approval from a cloud administrator. Which essential characteristic of cloud computing does this scenario best demonstrate?
Question 2
A solutions architect is planning a new web application on AWS. The workload will include 3 Amazon EC2 instances (t3.medium) running 24/7, an Application Load Balancer, and an Amazon RDS for MySQL db.t3.small database. The architect needs to estimate the monthly cost for the first year, considering different purchasing options (On-Demand, 1-year All Upfront Reserved Instance, and Compute Savings Plan). Which AWS tool should the architect use to create this estimate?
Question 3
A company's development team frequently needs temporary test environments. A developer can log into the AWS Management Console, select an Amazon EC2 instance type, configure storage, and launch the instance within minutes without any interaction with the IT infrastructure team. This capability is an example of which essential characteristic of cloud computing?
Question 4
A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?
Question 5
A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?
Question 6
A company uses AWS Organizations to manage multiple accounts. The security team needs to enforce a policy that restricts SSH access (port 22) from the internet (0.0.0.0/0) in all VPCs across all accounts. The team wants to centrally define the allowed rules and automatically apply them to newly created VPCs and security groups, while also automatically remediating any existing non-compliant security groups. Which AWS service should the team use?
FAQ
Questions learners often ask
What does this CLF-C02 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: AWS Systems Manager Patch Manager — AWS Systems Manager Patch Manager is the correct answer because it automates the process of patching managed nodes (EC2 instances and on-premises servers) with security-related and other types of updates. When used with AWS Organizations, Patch Manager can be configured to operate across multiple accounts using cross-account roles or AWS Systems Manager Quick Setup, enabling centralized patch baseline definition, scheduling, and compliance reporting via a single dashboard in the AWS Systems Manager console. AWS Config provides resource configuration tracking and compliance rules but does not perform patching. Amazon Inspector is a vulnerability assessment service that scans for software vulnerabilities and unintended network exposure, but it does not apply patches. AWS Trusted Advisor offers best practice checks and recommendations but does not provide patch management capabilities.
