Full question →mediummultiple choiceObjective-mapped
A global gaming company needs to deploy its application in multiple geographic locations to reduce latency for players worldwide. The application must also remain available even if an entire data center fails. The company plans to run the application on Amazon EC2 instances behind an Application Load Balancer. Which combination of AWS global infrastructure components should the company 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
Deploy the application in a single AWS Region across multiple Availability Zones and use Amazon Route 53 with latency-based routing.
This option only uses one AWS Region. While it provides fault tolerance through multiple Availability Zones, it does not reduce latency for players who are far from that single Region. It does not meet the global latency reduction requirement.
B
Distractor review
Deploy the application in a single AWS Region within a single Availability Zone and use Amazon CloudFront for content caching.
This option lacks both geographic distribution and data center redundancy. CloudFront does not run the application; it only caches static content. A single Availability Zone does not protect against the failure of an entire data center.
C
Best answer
Deploy the application in multiple AWS Regions, each with at least two Availability Zones, and use Amazon Route 53 for DNS-based routing.
Multiple AWS Regions provide geographic distribution to reduce latency globally. Using multiple Availability Zones within each Region ensures that the application remains available if an entire data center (one Availability Zone) fails. Amazon Route 53 can route users to the nearest healthy Region, meeting both requirements.
D
Distractor review
Deploy the application in multiple AWS Regions and use Amazon CloudFront with multiple origins, each pointing to an Application Load Balancer in a single Availability Zone.
Using CloudFront as a proxy does not run the application; it only accelerates content delivery. Moreover, using a single Availability Zone per Region does not protect against data center failures within that Region, violating the availability requirement.
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: Deploy the application in multiple AWS Regions, each with at least two Availability Zones, and use Amazon Route 53 for DNS-based routing. — To meet the requirements of low latency worldwide and fault tolerance against a data center failure, the company must use multiple AWS Regions (for geographic distribution) and multiple Availability Zones within each Region (for data center-level redundancy). Amazon Route 53 can route traffic to the nearest healthy Region, and Application Load Balancers distribute traffic across Availability Zones within a Region. Option C correctly describes this approach. Option A is incorrect because it only uses a single Region, which does not address global latency requirements. Option B is incorrect because a single Availability Zone does not provide fault tolerance against a data center failure, and CloudFront does not run the application itself. Option D is incorrect because using a single Availability Zone per Region does not protect against data center failures within that Region.
