In webapp1-test, you test several changes to App1.
You back up App1.
You swap webapp1-test for webapp1-prod and discover that App1 is experiencing performance issues.
You need to revert to the previous version of App1 as quickly as possible.
What should you do?
- A. Redeploy App1
- B. Swap the slots

Correct Answer: B
When you swap deployment slots, Azure swaps the Virtual IP addresses of the source and destination slots, thereby swapping the URLs of the slots. We can easily revert the deployment by swapping back.
