Question 1mediummulti select
Full question →mediummulti selectObjective-mapped
A team is splitting a new workload into two fronts. The first front serves HTTPS microservices that need host- and path-based routing plus health checks. The second front must handle TCP and UDP traffic for a real-time service and preserve static IP addresses for firewall allowlisting. Which two AWS load balancer choices best match these requirements? Select two.
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
Application Load Balancer
Application Load Balancer supports HTTP and HTTPS routing with host- and path-based rules, making it ideal for microservices.
B
Best answer
Network Load Balancer
Network Load Balancer handles TCP and UDP traffic and can preserve stable IP addresses for allowlisting.
C
Distractor review
Amazon API Gateway
API Gateway is useful for API management, but it is not a load balancer for arbitrary TCP or UDP traffic.
D
Distractor review
Amazon CloudFront
CloudFront accelerates content delivery at the edge, but it does not provide the required backend traffic balancing features.
E
Distractor review
Gateway Load Balancer
Gateway Load Balancer is for inserting third-party network appliances, not for application routing or real-time UDP services.
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.

A team needs to distribute TCP traffic (not HTTP) across multiple services. The services must see the original client source IP for auditing. Which AWS load balancer is the best fit?
Question 2
A team wants to run containerized services with AWS-managed orchestration and autoscaling. They do NOT require Kubernetes compatibility. Which AWS service choice is most appropriate to meet these goals?
Question 3
A solutions architect is designing an S3 bucket for a IoT ingestion API. The objects must never be publicly accessible, even if a developer later adds an overly broad bucket policy. What should the architect configure? The design must avoid adding custom operational scripts.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Application Load Balancer — Application Load Balancer is the best fit for the HTTP/HTTPS microservice front end because it supports host-based and path-based routing and integrates well with health checks. Network Load Balancer is the correct choice for the real-time service because it supports TCP and UDP and can provide stable IP addresses for firewall allowlisting. Together, they match the two distinct traffic patterns without forcing the workload into a single load balancer type. Why others are wrong: API Gateway is an API management service, not the right tool for arbitrary TCP or UDP balancing. CloudFront speeds up content delivery but does not replace a load balancer for these backend routing requirements. Gateway Load Balancer is used to chain network appliances such as firewalls or IDS solutions; it is not the correct front door for microservices or real-time UDP traffic.
