ANS-C01 Network Implementation Practice Question

This ANS-C01 practice question tests your understanding of network implementation. 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 wants to deploy a web application on EC2 instances behind an Application Load Balancer (ALB). The application must support sticky sessions (session affinity). What configuration is required on the ALB?

A
Enable stickiness on the target group and specify a cookie duration
Stickiness (session affinity) ensures the same client is routed to the same target.
B
Use path-based routing
Why wrong: Path-based routing directs traffic based on URL path, not for stickiness.
C
Configure health checks on the target group
Why wrong: Health checks are for monitoring target health, not for stickiness.
D
Enable proxy protocol v2
Why wrong: Proxy protocol adds client IP information but does not provide stickiness.

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

✓

Enable stickiness on the target group and specify a cookie duration

Sticky sessions (session affinity) are enabled at the target group level on an Application Load Balancer. By enabling stickiness and specifying a cookie duration, the ALB generates a session cookie (AWSALB) that binds a client's session to a specific target for the duration, ensuring subsequent requests from the same client are routed to the same EC2 instance.

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

✗
Use path-based routing
Why it's wrong here
Path-based routing directs traffic based on URL path, not for stickiness.
✗
Configure health checks on the target group
Why it's wrong here
Health checks are for monitoring target health, not for stickiness.
✗
Enable proxy protocol v2
Why it's wrong here
Proxy protocol adds client IP information but does not provide stickiness.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is confusing target group-level stickiness with listener-level routing rules (path-based) or connection metadata protocols (Proxy Protocol), leading candidates to select options that address different ALB features.

Detailed technical explanation

How to think about this question

The ALB uses a generated cookie named AWSALB by default, which is encrypted and includes the target group name and a timestamp. The cookie duration (idle timeout) resets on each request within the duration; after expiry, the client may be routed to a different target. For custom cookie-based stickiness, you can specify your own cookie name, but the ALB still manages the session binding.

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 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.
