Implementing DevOps Solutions and Practices Using Cisco Platforms (DEVOPS) — Question 7

A new version of an application is being released by creating a separate instance of the application that is running the new code. Only a small portion of the user base will be directed to the new instance until that version has been proven stable. Which deployment strategy is this example of?

Answer options

• A. recreate
• B. blue/green
• C. rolling
• D. canary

Correct answer: D

Explanation

The canary deployment strategy allows a small subset of users to test the new version of the application before it is rolled out to everyone, which helps in identifying issues early. The other options, such as blue/green and rolling, involve different methods of deploying updates that do not focus on a small user group testing first.
