Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company has a web application deployed on AWS in the us-west-2 Region. The application is accessed by users across the globe, including Europe, Asia, and South America. The company wants to improve the application's performance for international users by reducing latency and packet loss. The solution must route user traffic over the AWS global network to the closest edge location. Which AWS service should the company use?
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
Amazon CloudFront
Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations to improve delivery of static and dynamic web content. However, it is optimized for HTTP/HTTPS traffic and does not provide the same low-latency routing for non-HTTP protocols or for dynamic applications that cannot be cached. The scenario requires routing user traffic over the AWS global network to the closest edge location for any IP traffic, which is a capability of AWS Global Accelerator, not CloudFront.
B
Best answer
AWS Global Accelerator
AWS Global Accelerator is designed to improve the performance of global applications by directing user traffic over the AWS global network to the closest edge location. It uses anycast IP addresses and routes traffic to the optimal endpoint based on location, network conditions, and health. This reduces latency and packet loss for global users, making it the correct choice for the described requirements.
C
Distractor review
Amazon Route 53 (with latency-based routing)
Amazon Route 53 latency-based routing is a DNS-based routing policy that directs user requests to the AWS region with the lowest latency. However, DNS responses can be cached by intermediate resolvers, leading to suboptimal routing. Additionally, DNS routing only works at the DNS query level and does not directly optimize the network path for the actual traffic. AWS Global Accelerator provides more consistent and granular performance improvements.
D
Distractor review
AWS Direct Connect
AWS Direct Connect provides a dedicated private network connection from an on-premises data center to AWS, which can improve latency and security for traffic between the customer's network and AWS. However, it does not address the performance of global users accessing the application from different parts of the world. Direct Connect is typically used for hybrid cloud scenarios, not for improving global end-user experience.
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 Global Accelerator — AWS Global Accelerator is the correct service for this scenario. It uses the AWS global network to route user traffic to the optimal endpoint based on the user's location, network conditions, and endpoint health. It improves performance for global users by reducing internet latency and jitter. Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations but is optimized for HTTP/HTTPS requests and does not handle non-web traffic. Amazon Route 53 latency-based routing is a DNS-based method that can be affected by DNS caching and is not as fine-grained as Global Accelerator. AWS Direct Connect provides a dedicated network connection from an on-premises data center to AWS but does not address global user performance.
