Global Accelerator is the SAA-C03’s answer for global performance without caching. Where CloudFront caches content at the edge, Global Accelerator gets traffic onto the AWS backbone at the nearest edge and carries it to your regional endpoints — with static IPs and fast failover as bonuses. The exam mostly tests it against CloudFront and Route 53.

What it is

Global Accelerator provides two static anycast IP addresses as a fixed front door. User traffic enters at the closest edge location and travels over AWS’s private global backbone to the nearest healthy endpoint (an ALB, NLB, EC2, or Elastic IP) in any Region — avoiding the congested public internet. That path optimisation is the latency win, and it works for TCP and UDP, not just HTTP.

Global Accelerator vs CloudFront

The distinction the exam plants:

CloudFront — caches content at the edge. For static, cacheable HTTP/HTTPS delivery.
Global Accelerator — does not cache; it accelerates traffic over the backbone. For dynamic, non-cacheable content, non-HTTP protocols, static IPs, and fast failover.

If the content is cacheable → CloudFront. If it is non-cacheable, non-HTTP, or needs static IPs and rapid failover → Global Accelerator.

Static IPs and fast failover

Two properties recur in the answers. The two static anycast IPs are ideal when a partner must allowlist a stable entry point while you change endpoints behind it. And failover is DNS-free: because the IPs never change, Global Accelerator health-checks endpoints and reroutes to a healthy Region within seconds, with no DNS TTL to wait on — a clear advantage over Route 53 failover.

Traffic dial

For controlled rollouts, the traffic dial and endpoint weights shift a percentage of traffic between regional endpoint groups — the answer to “gradually move traffic from one Region to another”.

How to use the six scenarios below

Answer each one before opening the explanation, and when you miss, name what decided it — “non-HTTP/UDP”, “static IPs to allowlist”, “non-cacheable”, “failover in seconds”, “shift traffic gradually”, “AWS backbone”. Every explanation states that requirement and dismantles the distractors, most of which offer CloudFront where caching does not apply. For the domain overview, see Design High-Performing Architectures.

AWS Global Accelerator giving an application two static anycast IP addresses at the edge. User traffic enters at the nearest edge location and travels over the AWS global backbone to healthy regional endpoints such as load balancers in different Regions, rather than over the public internet. Health checks reroute traffic to a healthy Region within seconds, and a traffic dial shifts the share of traffic between regional endpoints. Unlike CloudFront it does not cache content; it accelerates dynamic, non-cacheable TCP and UDP traffic.

SAA-C03 Question 1 of 6

A multiplayer gaming backend uses a custom UDP protocol, serves players worldwide, and needs the lowest possible latency plus fast failover between regional endpoints. Which service best meets this?

Answer: A — AWS Global Accelerator.

Global Accelerator routes TCP and UDP traffic over the AWS global backbone from the nearest edge to healthy regional endpoints, with fast failover — ideal for a latency-sensitive global UDP game. Why not the others: CloudFront is a CDN for cacheable HTTP content and does not accelerate a custom UDP protocol. Route 53 latency routing resolves DNS to a Region but does not carry traffic over the AWS backbone or fail over in seconds. A single-Region ALB cannot serve a global audience with low latency. Global, non-HTTP, low-latency with fast failover is Global Accelerator.

SAA-C03 Question 2 of 6

A company needs a fixed, static entry point — a small set of IP addresses that never change — in front of application endpoints spread across multiple Regions, so a partner can allowlist them. Which service provides this?

Answer: A — AWS Global Accelerator, which provides two static anycast IP addresses.

Global Accelerator gives you two static anycast IP addresses that act as a fixed front door to endpoints in any Region — perfect for a partner allowlist that must not change. Why not the others: CloudFront's edge IPs are managed by AWS and not a stable pair you allowlist. Per-Region ALB DNS names resolve to changing IPs and are multiple, not a fixed pair. A Route 53 alias resolves names but does not itself provide static anycast IPs fronting multiple Regions. Fixed static IPs across Regions are Global Accelerator.

SAA-C03 Question 3 of 6

An application delivers dynamic, non-cacheable API responses to a global audience and needs to reduce latency by routing over an optimized network path rather than caching. Which service is appropriate?

Answer: A — AWS Global Accelerator.

Global Accelerator improves performance for dynamic, non-cacheable traffic by carrying it over the AWS backbone to the nearest healthy endpoint — acceleration without caching. Why not the others: CloudFront's benefit is caching; using it purely with caching disabled forgoes its main advantage and is not the intended tool for non-cacheable acceleration. S3 Transfer Acceleration speeds uploads to S3 buckets specifically. Read replicas scale database reads, not general API latency. Accelerating dynamic, non-cacheable traffic is Global Accelerator; caching static content is CloudFront.

SAA-C03 Question 4 of 6

A global application runs identical stacks in two Regions behind Global Accelerator. If one Region's endpoint becomes unhealthy, traffic must move to the healthy Region quickly. How does Global Accelerator handle this?

Answer: A — It health-checks the endpoints and reroutes traffic to a healthy endpoint within seconds.

Global Accelerator continuously health-checks endpoints and shifts traffic to a healthy endpoint within seconds, because the static anycast IPs stay the same — there is no DNS change or TTL to wait on. Why not the others: it does not cache responses (that is CloudFront). No manual DNS change is needed, which is a key advantage over DNS-based failover. And it does not depend on DNS TTL expiry, precisely the delay it removes. Fast, DNS-free regional failover is Global Accelerator.

SAA-C03 Question 5 of 6

A team wants to gradually shift a percentage of production traffic from one regional endpoint to another for a controlled rollout, using Global Accelerator. Which capability enables this?

Answer: A — The traffic dial (endpoint weights) on the endpoint groups.

Global Accelerator's traffic dial and endpoint weights let you control what share of traffic each regional endpoint group receives, so you can shift traffic gradually for a controlled rollout. Why not the others: a CloudFront cache behavior routes by path within a CDN distribution, not a percentage of traffic across Regions. An SQS queue decouples producers and consumers; it does not steer live user traffic. DNS TTL affects caching of DNS answers, not weighted traffic distribution. Gradual, weighted traffic shifting is the traffic dial.

SAA-C03 Question 6 of 6

Why does Global Accelerator reduce latency for global users compared with sending traffic over the public internet?

Answer: A — Traffic enters at the nearest edge and travels over the AWS global backbone to the endpoint, avoiding congested public internet paths.

Global Accelerator gets users onto the AWS network at the closest edge and carries their traffic over AWS's private global backbone to the application, avoiding the variable, congested public internet — that path optimisation is the latency win. Why not the others: caching at edge locations describes CloudFront, not Global Accelerator. It does not rely on packet compression, and it does not convert UDP to HTTP — it preserves the protocol. Routing over the AWS backbone is the mechanism.

Frequently asked questions

Global Accelerator or CloudFront — how do I choose?

CloudFront is a CDN: it caches content at the edge and is the answer for static, cacheable HTTP/HTTPS delivery. Global Accelerator does not cache; it accelerates traffic (including non-HTTP TCP/UDP) over the AWS backbone to regional endpoints, and provides static anycast IPs and fast failover. Cacheable content → CloudFront; non-cacheable or non-HTTP with static IPs and fast failover → Global Accelerator.

What are the two static IPs for?

Global Accelerator gives you two static anycast IP addresses that act as a fixed front door to your endpoints in any Region. They are ideal when clients or partners must allowlist a stable set of IPs while you keep the flexibility to change endpoints behind them.

Are these real exam questions?

No. They are original scenarios written for this page in the exam's style and difficulty. Reproducing real exam items violates the AWS certification agreement and can cost a candidate their certification — ours come with the reasoning attached instead.

What is the one-line takeaway?

Global Accelerator gives static anycast IPs and routes non-cacheable TCP/UDP traffic over the AWS backbone with fast, DNS-free failover — use it where CloudFront's caching does not apply.
