Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A mobile gaming company is developing a real-time multiplayer game that requires ultra-low latency (under 10 milliseconds) for player interactions. The company expects most of its users to be on 5G mobile networks. To meet the latency requirement, the company needs to deploy compute and storage resources as close as possible to the mobile subscribers, directly at the edge of the telecommunications network. 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 Wavelength
Correct. AWS Wavelength brings AWS compute and storage to the edge of 5G networks, providing ultra-low latency for mobile applications such as real-time gaming, AR/VR, and live video processing. This service is purpose-built for scenarios where latency to mobile subscribers is critical and the application must run within the telecom network edge.
B
Distractor review
AWS Local Zones
AWS Local Zones place compute, storage, and database services closer to large population centers to provide single-digit millisecond latency for end users. However, they do not embed directly within 5G mobile networks and are not optimized for sub-10ms latency requirements specifically for mobile subscribers on 5G.
C
Distractor review
AWS Outposts
AWS Outposts extend AWS infrastructure and services to on-premises or edge locations that the customer controls. While it provides low latency for local workloads, it is not designed to be deployed within a telecommunications provider's 5G network and does not offer the same level of integration with mobile subscribers.
D
Distractor review
Amazon CloudFront Edge Locations
Amazon CloudFront edge locations are points of presence that cache and deliver content (e.g., static files, video) to users with low latency. They are not designed to run general-purpose compute workloads for real-time multiplayer game logic; they are primarily for content delivery and do not provide the same computational capabilities required for interactive gaming.
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 designed to provide ultra-low latency for 5G and mobile edge computing applications. It embeds AWS compute and storage services at the edge of 5G networks, directly within telecommunications providers' data centers, minimizing latency and enabling real-time applications like multiplayer gaming. AWS Local Zones offer single-digit millisecond latency for end users in metropolitan areas but don't integrate directly with 5G networks. AWS Outposts extends AWS infrastructure to on-premises locations, not to telecom edge. CloudFront edge locations are optimized for content delivery and caching, not for running interactive compute workloads that require sub-10ms latency.
