The harbor-ferry App Service site cannot go dark during weekday deploys, and the team needs a warm staging URL before production sees the build. What should the developer create?
Select an answer to reveal the explanation.
Short Explanation
A deployment slot is a live twin of the app on the same plan—push there, poke it, then swap. That keeps the ferry site up for weekday riders. Container Apps revisions are a different host; do not swap those into an App Service question.
Full Explanation
Deployment slots provide an additional live site under the same App Service app for staging, testing, and zero-downtime swap. Container Apps revisions solve a similar problem on Container Apps, not App Service. Extra plans or Functions apps are not the slot feature.
