- A
Enable stickiness on each ALB individually and use a single Regional endpoint group.
Why wrong: ALB stickiness is per ALB, not cross-Region, so failover would lose sessions.
- B
Configure Global Accelerator to use session affinity with the 'two-tuple' protocol.
Why wrong: Global Accelerator does not support session affinity; traffic is distributed based on traffic dials and health.
- C
Configure Route 53 with latency-based routing and enable stickiness on each ALB.
Why wrong: Route 53 does not provide session persistence; stickiness is per ALB and not maintained on failover.
- D
Use a custom application cookie for stickiness that is consistent across all ALBs, and set the cookie domain to the Global Accelerator DNS name.
A custom cookie with a shared domain allows session persistence across ALBs in different Regions.
ANS-C01 Network Design Practice Question
This ANS-C01 practice question tests your understanding of network design. 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 is designing a multi-Region Active-Active architecture using Application Load Balancers (ALBs) behind AWS Global Accelerator. The application requires sticky sessions (session affinity) and must maintain session persistence even during failover. Which configuration should be used to achieve this?
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
Use a custom application cookie for stickiness that is consistent across all ALBs, and set the cookie domain to the Global Accelerator DNS name.
Option D is correct because AWS Global Accelerator does not natively support session affinity (sticky sessions). To maintain session persistence across multi-Region ALBs during failover, you must use a custom application cookie that is consistent across all ALBs and set the cookie domain to the Global Accelerator DNS name. This ensures the client's browser sends the same cookie to any healthy ALB in any Region, preserving the session even when traffic shifts due to a failover.
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.
- ✗
Enable stickiness on each ALB individually and use a single Regional endpoint group.
Why it's wrong here
ALB stickiness is per ALB, not cross-Region, so failover would lose sessions.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume Global Accelerator can provide session affinity natively, similar to an ALB's stickiness feature, but Global Accelerator is a Layer 3/4 service and cannot maintain application-layer session state; the solution requires a custom cookie approach at the application level.
Detailed technical explanation
How to think about this question
Under the hood, Global Accelerator uses Anycast IPs and edge locations to route traffic to the nearest healthy endpoint, but it operates at Layer 3/4 and does not inspect application-layer cookies. By setting the cookie domain to the Global Accelerator DNS name (e.g., `*.awsglobalaccelerator.com`), the client's browser sends the same cookie to any ALB endpoint, regardless of Region. This approach relies on the application generating a consistent session identifier, which is critical for stateful workloads like e-commerce shopping carts or gaming sessions that must survive a regional outage.
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.
