Actual exam question for CompTIA's CV0-004 exam

Question #: 42
Topic #: 3

[All CV0-004 Questions]

A developer is deploying a new version of a containerized application. The DevOps team wants:

* No disruption

* No performance degradation

* Cost-effective deployment

* Minimal deployment time

Which of the following is the best deployment strategy given the requirements?

ACanary

BIn-place

CBlue-green

DRolling

Show Suggested Answer

Suggested Answer: C

The blue-green deployment strategy is the best given the requirements for no disruption, no performance degradation, cost-effective deployment, and minimal deployment time. It involves maintaining two identical production environments (blue and green), where one hosts the current application version and the other is used to deploy the new version. Once testing on the green environment is complete, traffic is switched from blue to green, ensuring a seamless transition with no downtime. Reference: Understanding various cloud deployment strategies, such as blue-green deployments, is essential for managing cloud environments effectively, as highlighted in the CompTIA Cloud+ objectives, to ensure smooth and efficient application updates.

Canary deployment is the best option. Gradual rollout and easy to monitor for issues.

I practiced a similar question, and I feel like blue-green is the safest option for meeting all those requirements.

Rolling updates could work too, but I'm worried about potential performance issues during the transition.

I'm not entirely sure, but I remember something about canary deployments being good for testing new features with minimal risk.

I think the blue-green deployment might be the best choice here since it allows for zero downtime and quick rollbacks if something goes wrong.

The rolling deployment sounds promising, but I'm not sure if it meets the requirement for minimal deployment time. I'll need to research this a bit more.

I'm a bit confused on the differences between these strategies. Maybe I should review my notes on deployment techniques before deciding.

Canary could work, but it might not be the most cost-effective. I'm leaning towards the blue-green approach, but I'll need to double-check the details.

Okay, let's see. Minimal disruption and no performance degradation are key. I think the blue-green or rolling strategies might be the best fit here.

Hmm, this seems like a tricky one. I'll need to carefully consider the requirements and weigh the pros and cons of each deployment strategy.
