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. Deployment slots are live apps with their own host names. App content and configurations elements can be swapped between two deployment slots, including the production slot. Deploying your application to a non-production slot has the following benefits: 1. You can validate app changes in a staging deployment slot before swapping it with the production slot. 2. Deploying an app to a slot first and swapping it into production makes sure that all instances of the slot are warmed up before being swapped into production.

Correct Swap slots. this is advantage of using slots. where each slot has its own host name while the app content and configuration elements are the one who are swapped. this is done seamlessly for traffic direction and no requests are dropped or downtime happens.

B is the answer. https://learn.microsoft.com/en-us/azure/app-service/deploy-staging-slots#roll-back-a-swap If any errors occur in the target slot (for example, the production slot) after a slot swap, restore the slots to their pre-swap states by swapping the same two slots immediately.
