- A
AWS WAF
Why wrong: WAF provides security filtering, not encryption.
- B
Application Load Balancer (ALB)
ALB can terminate SSL/TLS and route traffic to targets.
- C
NAT Gateway
Why wrong: NAT Gateway is for outbound internet access, not inbound encryption.
- D
AWS Certificate Manager (ACM)
ACM provides SSL/TLS certificates for the ALB.
- E
Amazon CloudFront
Why wrong: CloudFront can serve content but is not required for encryption; ALB+ACM is simpler.

ANS-C01 Network Design Practice Question
This ANS-C01 practice question tests your understanding of network design. 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 is deploying a web application in a VPC. They need to ensure that the web servers can be accessed from the internet and that traffic is encrypted. Which TWO services should they use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Application Load Balancer (ALB)
The Application Load Balancer (ALB) is correct because it can terminate TLS connections, offloading encryption from the web servers, and it distributes incoming internet traffic across multiple targets in a VPC. Combined with AWS Certificate Manager (ACM), the ALB can use a managed SSL/TLS certificate to encrypt traffic between clients and the load balancer, meeting the requirement for encrypted internet access.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Amazon CloudFront
Why it's wrong here
CloudFront can serve content but is not required for encryption; ALB+ACM is simpler.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often select CloudFront (Option E) thinking it is required for encryption, but the ALB with ACM directly provides TLS termination and internet-facing access without needing a CDN, and the question specifically asks for two services that ensure encrypted internet access, not content delivery optimization.
Detailed technical explanation
How to think about this question
The ALB uses listener rules to terminate TLS at the load balancer using certificates from ACM, which supports automatic renewal of public certificates via DNS validation. Under the hood, the ALB negotiates TLS 1.2 or 1.3 with clients, then forwards plaintext HTTP to backend targets, reducing CPU overhead on web servers. In a real-world scenario, you might also integrate AWS WAF with the ALB for additional security, but the core requirement of encrypted internet access is satisfied by the ALB and ACM alone.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
