The answer is to configure the ALB with an appropriate security policy that enforces TLS 1.2 or higher. This is correct because an Application Load Balancer’s security policy defines the supported TLS protocols and ciphers, allowing you to explicitly deny connections using older, less secure versions like TLS 1.0 or 1.1. AWS Certificate Manager (ACM) only provisions and manages the certificate itself, not the protocol negotiation, so the security policy on the ALB is the precise control point for enforcing TLS version requirements. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this concept tests your understanding of how to secure traffic at the load balancer layer, often appearing in scenarios where compliance mandates must be met without relying on backend configuration. A common trap is confusing ACM’s role with protocol enforcement or assuming CloudFront or Route 53 can handle this—they cannot. Memory tip: think of the security policy as the ALB’s bouncer that checks the TLS handshake ID, while ACM just provides the ID card.
ANS-C01 Network Security, Compliance and Governance Practice Question
This ANS-C01 practice question tests your understanding of network security, compliance and governance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 uses AWS Certificate Manager (ACM) to provision SSL/TLS certificates for their Application Load Balancer (ALB). They want to ensure that the ALB only accepts connections using TLS 1.2 or higher. How should they configure this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure the ALB with an appropriate security policy that enforces TLS 1.2.
Option C is correct because security policies on the ALB can specify the TLS version. Option A is wrong because ACM does not control TLS version; it provides certificates. Option B is wrong because CloudFront is a different service. Option D is wrong because Route 53 does not handle TLS version enforcement.
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.
✗
Use ACM to generate a certificate that only supports TLS 1.2.
Why it's wrong here
ACM certificates support multiple TLS versions; the certificate itself does not enforce version.
✓
Configure the ALB with an appropriate security policy that enforces TLS 1.2.
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
