Full question →mediummultiple choiceObjective-mapped
A company runs a globally distributed multiplayer game on AWS. The game uses UDP for real-time communication and requires static IP addresses that do not change for whitelisting by internet service providers. The company needs to route traffic to the nearest healthy application endpoint to minimize latency and improve performance. The solution must work with both TCP and UDP traffic and provide static IP addresses. 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
Best answer
AWS Global Accelerator
Correct. AWS Global Accelerator provides static IP addresses and optimizes the path from users to applications over TCP/UDP, routing traffic to the nearest healthy endpoint using the AWS global network.
B
Distractor review
Amazon CloudFront
Incorrect. Amazon CloudFront is a CDN that caches and delivers content over HTTP/HTTPS only. It does not support UDP traffic and does not provide static IP addresses for application endpoints.
C
Distractor review
Amazon Route 53
Incorrect. Amazon Route 53 is a DNS service that translates domain names to IP addresses but does not provide static IP addresses. DNS responses can change based on routing policies, and Route 53 alone does not optimize network paths for UDP traffic.
D
Distractor review
AWS Direct Connect
Incorrect. AWS Direct Connect is a dedicated private connection between on-premises data centers and AWS, used for hybrid architectures. It does not provide global traffic routing with static IPs for internet-facing applications.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

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?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: AWS Global Accelerator — AWS Global Accelerator is a networking service that improves performance for a wide range of applications over TCP and UDP by routing user traffic to the nearest healthy endpoint using static IP addresses. It uses the global AWS infrastructure to reduce latency and jitter. Amazon CloudFront is a content delivery network (CDN) that only supports HTTP and HTTPS, not UDP. Amazon Route 53 is a DNS service that resolves domain names to IP addresses but does not provide static IP addresses for traffic routing — it returns different IPs based on DNS resolution. AWS Direct Connect establishes a dedicated private network connection from on-premises to AWS, which is not designed for global traffic routing with static IPs.
