Cloud Technology and Services →mediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is AWS Global Accelerator. This service is the correct choice because it uses the AWS global network to route UDP traffic over optimized paths to the nearest healthy application endpoint, significantly reducing latency and jitter for real-time gaming. It also provides two static anycast IP addresses that act as a fixed entry point, masking changes to the underlying infrastructure while improving connection stability for players in different geographic regions. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of how Global Accelerator differs from CloudFront—a common trap is confusing the two, but remember that CloudFront is for HTTP/HTTPS content delivery and caching, while Global Accelerator handles both TCP and UDP traffic with static IPs for performance optimization. A helpful memory tip: think of Global Accelerator as the "UDP-friendly traffic cop" that gives your app a fixed, static address while routing players to the fastest regional endpoint.

CLF-C02 Cloud Technology and Services Practice Question

This CLF-C02 practice question tests your understanding of cloud technology and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company runs a multiplayer gaming application on AWS. The application uses UDP for real-time communication between players. Players in different geographic regions report high latency and connection instability. The company wants to improve performance by directing user traffic to the nearest healthy application endpoint and using a static IP address for the application. Which AWS service should the company use to meet these requirements?

Correct answer & explanation

✓

AWS Global Accelerator

AWS Global Accelerator uses the AWS global network to route UDP traffic over optimized paths to the nearest healthy application endpoint, reducing latency and jitter. It provides two static anycast IP addresses that act as a fixed entry point, masking changes to underlying infrastructure. This directly addresses the need for low-latency UDP communication and a static IP for the gaming application.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Amazon CloudFront

    Why it's wrong here

    CloudFront is a content delivery network for HTTP/HTTPS traffic only. It does not support UDP protocols, so it cannot be used for the gaming application's real-time UDP communication.

  • ✓

    AWS Global Accelerator

    Why this is correct

    Global Accelerator uses static anycast IP addresses and the AWS global network to optimize the path for TCP and UDP traffic. It automatically routes users to the nearest healthy application endpoint, improving latency and connection stability for real-time applications.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Amazon Route 53

    Why it's wrong here

    Route 53 is a DNS web service that translates domain names to IP addresses. It can route traffic based on policies like latency-based routing, but it does not provide static IP addresses or optimize the actual network path for UDP traffic.

  • ✗

    AWS Direct Connect

    Why it's wrong here

    Direct Connect establishes a dedicated private network connection between an on-premises data center and AWS. It is not a service to improve internet application performance for global users and does not provide static IP addresses or health-based routing.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse Amazon CloudFront's edge caching with network path optimization, but CloudFront does not support UDP traffic or provide static IP addresses, making AWS Global Accelerator the correct choice for real-time UDP applications.

Detailed technical explanation

How to think about this question

AWS Global Accelerator leverages the Anycast routing technique, where the same static IP address is advertised from multiple AWS edge locations, so user traffic naturally flows to the nearest edge location via BGP routing. It then forwards traffic over the AWS global backbone to the optimal regional endpoint (e.g., an Application Load Balancer or Network Load Balancer), bypassing the public internet to reduce latency and packet loss. For UDP-based gaming, this avoids the connection overhead and retransmission issues common with TCP, while the static IP ensures client firewall rules and peer-to-peer discovery remain stable even during failover.

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.

TExam Day Tips

  • 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.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.

Same concept, more angles

2 more ways this is tested on CLF-C02

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. A company wants to deploy their application globally and needs AWS to automatically route users to the nearest healthy application endpoint with improved network performance. Which AWS service uses the AWS global network backbone for routing optimization?

medium
  • A.Amazon CloudFront
  • ✓ B.AWS Global Accelerator
  • C.Amazon Route 53 with latency routing
  • D.Amazon VPC peering

Why B: AWS Global Accelerator uses the AWS global network backbone to optimize the path from users to applications. It routes traffic over the AWS internal network rather than the public internet, improving performance and reliability. It also automatically directs users to the nearest healthy endpoint, meeting the requirement for global deployment with automatic failover.

Variation 2. A media company streams live video to a global audience. The application runs on Application Load Balancers in two AWS Regions (us-east-1 and eu-west-1). The company's clients require the use of a fixed set of static IP addresses for firewall allowlisting. The company needs to route user traffic to the nearest healthy endpoint to minimize latency. Which AWS service should the company use?

medium
  • A.Amazon CloudFront
  • ✓ B.AWS Global Accelerator
  • C.Network Load Balancer
  • D.Amazon Route 53 latency-based routing

Why B: AWS Global Accelerator provides two static Anycast IP addresses that serve as fixed entry points for traffic, which are then routed over the AWS global network to the nearest healthy endpoint (e.g., Application Load Balancer in us-east-1 or eu-west-1). This minimizes latency by directing users to the closest Region while preserving the static IPs required for firewall allowlisting. Unlike CloudFront, Global Accelerator does not cache content and is optimized for TCP/UDP traffic, making it ideal for live video streaming where low latency and static IPs are critical.
