Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company is developing a real-time multiplayer game that requires extremely low latency (under 10ms) for player interactions. The game will be accessed by mobile users on 5G networks in select metropolitan areas. The company wants to run the game server logic as close to the users as possible, leveraging the low latency of 5G and avoiding the round trip to an AWS Region. Which AWS service should the company use to deploy the game server compute at the edge of the 5G network?
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 Outposts
AWS Outposts bring native AWS services to on-premises data centers, but they are designed for hybrid cloud use cases, not for embedding compute within a 5G mobile network. Outposts would not provide the sub-10ms latency required for a 5G edge gaming scenario.
B
Distractor review
AWS Local Zones
AWS Local Zones place compute resources closer to end users in specific metropolitan areas, reducing latency compared to an AWS Region. However, they are not embedded within the 5G network operator's infrastructure. While they reduce latency, they typically do not achieve the extremely low latencies needed for real-time interactive 5G applications.
C
Best answer
AWS Wavelength
AWS Wavelength is the correct choice. It embeds AWS compute and storage at the edge of 5G networks, directly within the mobile network operator's data centers. This enables developers to build applications that require ultra-low latency (single-digit milliseconds) for mobile devices on 5G, ideal for real-time gaming.
D
Distractor review
AWS Global Accelerator
AWS Global Accelerator improves the availability and performance of applications by directing traffic over the AWS global network to the optimal endpoint. It does not deploy compute resources at the edge; it only optimizes routing. Therefore, it cannot satisfy the requirement of running game server logic at the 5G edge.
Common exam trap
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Technical deep dive
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.

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?
OSPF neighbours must agree on key parameters.
What is the correct answer to this question?
The correct answer is: AWS Wavelength — AWS Wavelength is purpose-built for edge computing on 5G networks. It embeds AWS compute and storage at the edge of telecom providers' 5G networks, enabling developers to build applications that require ultra-low latency for mobile and connected devices. This is the correct choice for running game server logic directly within the 5G network infrastructure, minimizing latency to under 10ms. AWS Outposts extend AWS infrastructure to on-premises data centers but are not integrated with 5G. AWS Local Zones place compute closer to users but are not embedded within mobile network operators. AWS Global Accelerator improves routing and traffic distribution but does not deploy compute at the edge.
