Exam AZ-400 topic 1 question 16 discussion

A is the right anser. Blue/green and Red/Black are same. Must be 2 ['colored' paths] to swap immediately between them. Read the line "The strategy should also allow you to roll back in the shortest time required".So answer is A.

2 colors deployment whatever the color set you learned

Red black same as blue green

Red/black = Blue/Green = 0X111/ 0X000 Its done with deployment slots which takes the time to minimum, and can be reversed at the same pace using swap operation.

A is the answer. https://learn.microsoft.com/en-us/training/modules/implement-blue-green-deployment-feature-toggles/2-what-blue-green-deployment This technique can eliminate downtime because of app deployment. Besides, blue-green deployment reduces risk: if something unexpected happens with your new version on the green, you can immediately roll back to the last version by switching back to blue.

A. Blue-Green deployment.

This question appears much later in topic 7 or 8. The answer is "voted" to rolling deployment. This question needs to be flagged for review or removal since there's contradicting information.

I think A. Blue/Green deployment

Cannot find Red/Black anywhere on MS pages. Maybe the term was changed in the past, meaning this question should be updated to current documentation and definitions. According to the current documentation only Canary release can be the correct one.

Correct !`

Provided answer is correct

D. Canary deployment

Canary should be right answer. As in case of red black deployment , application is deployed to black environment . Testing is done on black environment . Only after testing application is routed to black environment from red one. Canary can be faster but can have higher risk than red black

Answer section shows a description of Canary deployment instead of Blue/Green Deployment (Red/Black in this case) which is the right answer (A).

Answer is A for sure

Red/Black with the deployment slots.

A is correct answer however this is usually referred to as “Blue/Green”.
