A developer deploys a web app to an Azure App Service staging slot using `az webapp deploy`. The app works in staging, but after swapping to production, users report the app is showing old cached JavaScript files. The developer wants to ensure clients fetch the latest assets after future swaps without changing the app code. What should the developer do?

Use the `WEBSITE_SWAP_SLOTNAME` app setting to force a cache refresh on swap.

Add a `Cache-Control: no-cache` response header for static assets in `web.config` or `appsettings.json`.

Enable 'ARR affinity' on the production slot.

Configure the app to include a content hash or version query string in static asset URLs.

A company runs a web API on an Azure App Service Standard plan. The API experiences predictable traffic spikes every weekday from 9 AM to 11 AM. The company wants to scale out automatically during that window and scale back afterward to control costs. What should they configure?

A scheduled autoscale condition with a recurring profile for weekdays 9 AM–11 AM.

A scale rule based on request count with a 5-minute evaluation period.

Manual scaling to the peak instance count and leave it there.

A scale rule based on CPU percentage with a 10-minute cool-down.

A company exposes a REST API on Azure App Service. They want to restrict access to clients that present a valid API key in the `x-api-key` header. The API key is stored in an App Service application setting. What should the developer do?

Use the built-in 'Access Restrictions' feature to allow only specific IP addresses.

Enable 'Authentication/Authorization' with Azure Active Directory.

Set the `WEBSITE_AUTH_ENABLED` setting to require a client certificate.

Implement a custom middleware that checks the header against the application setting.
