CompTIA CV0-004 Exam - Topic 3 Question 42 Discussion

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?

Show Suggested Answer Hide 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.

I think rolling updates could work too, but not sure about cost-effectiveness.

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.

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.
