Exam Professional Cloud Architect topic 1 question 45 discussion

I believe the best answer is D, because the tagging is a best practice that is recommended on Jenkins/Spinnaker to deploy the right code and prevent accidentally (or intentionally) push of wrong code to production environments. See https://stackify.com/continuous-delivery-git-jenkins/

I got this question in real exam. This question states "before deploying to production" environment. So i picked D . I passed the exam.

1. Clear separation of environments: Using separate staging and production environments ensures that code changes are thoroughly tested before they reach your users. This minimizes the risk of introducing bugs or regressions into production. 2. Controlled deployments: Tagging the repository for different stages (staging, production) provides a clear and auditable way to track which code versions are deployed in each environment. This makes it easier to roll back to a previous version if necessary. 3. Jenkins for automation: Jenkins is a powerful automation server that can monitor your Git repository for new tags, automatically build and deploy the code to the appropriate environment, and even trigger automated tests. 4. Comprehensive testing: A staging environment allows you to perform comprehensive testing, including integration testing, user acceptance testing (UAT), and performance testing, before deploying to production.

D is the best choice.

ABC is about to deploy to production without prior testing. Hence D is the only reasonable choice.

A B and C are very risky options and irrelevant as involving production. Whereas question is to test before rolling out to production. Hence D

No discussion here.

ok for D

Given the question D is the only answer. Everything else pushes to production immediately.

I don't think it was a good idea when new edtion be created and directly deploy to the production ENV without any testing stage even using Canary deployment.

The question states: "... code changes can be verified BEFORE deploying to production", it eliminates option C. The approach of tagging is the correct practise that DevOps use

Correct answer is D. Question talks about 'before deploying to production'. C talks about after deploying to production.

C is the closest answer If question is asking 'what's Jenkin best practise' then D is the answer

I choose D as we want to ensure that code changes can be verified BEFORE deploying to production. Option C suggests that we build and deploy changes to production for 10% of users.

Vote D. C is canary deploy. But the sentence in question has no word to mean "tested by a small number of users"

D is the correct answer
