- A
Perform a rolling update by terminating one instance at a time and launching a new one.
Why wrong: Rolling updates may cause temporary capacity loss.
- B
Implement a blue/green deployment by creating a new target group and updating the ALB listener.
Blue/green allows instant traffic switch with no downtime.
- C
Create a new ALB and update the DNS record to point to the new ALB.
Why wrong: DNS changes take time to propagate, causing potential downtime.
- D
Use a canary release by routing 10% of traffic to the new version.
Why wrong: Canary release is not fully zero downtime if the old version is still in use.

PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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 running SAP BusinessObjects on AWS. The application servers are behind an Application Load Balancer (ALB). The ALB is configured to use a single target group. The company wants to deploy a new version of the application with zero downtime. Which deployment strategy should be used?
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
✓
Implement a blue/green deployment by creating a new target group and updating the ALB listener.
Option B is correct because a blue/green deployment allows you to create a completely new target group with the new application version, then update the ALB listener rule to route all traffic from the existing target group to the new one. This ensures zero downtime because the switch is instantaneous at the listener level, and the old environment remains intact for immediate rollback if needed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse a rolling update (which can cause brief downtime) with a blue/green deployment (which provides instant, zero-downtime cutover), especially when the question explicitly requires zero downtime and the ALB is already in place.
Detailed technical explanation
How to think about this question
Blue/green deployments leverage ALB listener rules that can be updated atomically via the ModifyListener API, allowing traffic to be shifted instantly from the blue target group to the green target group. This approach is particularly important for stateful applications like SAP BusinessObjects, where session persistence (sticky sessions) must be maintained; the ALB can be configured with stickiness enabled on the target group, and the switchover preserves existing sessions if the new group is pre-warmed. In real-world scenarios, you would also pre-register the new target group with the ALB and run health checks before flipping the listener rule to ensure the new version is ready.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
