hTTPS on a custom name requires ownership mapping plus a valid certificate and TLS binding. In this case, a certificate for an App Service custom hostname is expiring. “A custom domain binding and appropriate TLS certificate binding” would not satisfy that requirement; the supported action is “The TLS certificate bound to that hostname”. Certificate validity and binding determine whether clients trust the custom-domain HTTPS endpoint.

clients validate that the certificate covers the host name presented in the URL. In this case, a certificate for an App Service custom hostname is expiring. “The custom domain TLS binding and certificate subject names” would not satisfy that requirement; the supported action is “The TLS certificate bound to that hostname”. Certificate validity and binding determine whether clients trust the custom-domain HTTPS endpoint.

a minimum TLS version rejects older client protocol negotiations while HTTPS policy enforces encrypted requests. In this case, a certificate for an App Service custom hostname is expiring. “App Service minimum TLS version and HTTPS enforcement” would not satisfy that requirement; the supported action is “The TLS certificate bound to that hostname”. Certificate validity and binding determine whether clients trust the custom-domain HTTPS endpoint.

hTTPS on a custom name requires ownership mapping plus a valid certificate and TLS binding. In this case, a team needs a DNS name such as portal.example.com pointing to an App Service. “A custom domain binding and appropriate TLS certificate binding” would not satisfy that requirement; the supported action is “Create the appropriate DNS CNAME or supported record plus domain validation”. Custom hostname mapping relies on DNS records and validation before the binding becomes active.

domain validation establishes control of the requested hostname before it is accepted by the service. In this case, a team needs a DNS name such as portal.example.com pointing to an App Service. “Complete the App Service custom-domain ownership validation” would not satisfy that requirement; the supported action is “Create the appropriate DNS CNAME or supported record plus domain validation”.

a minimum TLS version rejects older client protocol negotiations while HTTPS policy enforces encrypted requests. In this case, a security policy forbids unencrypted HTTP requests to the app. “App Service minimum TLS version and HTTPS enforcement” would not satisfy that requirement; the supported action is “Enable HTTPS Only for the App Service app”. HTTPS Only redirects HTTP requests to HTTPS for the supported web endpoint.

app Service bindings do not automatically modify every external DNS provider's record. In this case, a security policy forbids unencrypted HTTP requests to the app. “Update the public DNS mapping to the App Service endpoint” would not satisfy that requirement; the supported action is “Enable HTTPS Only for the App Service app”. HTTPS Only redirects HTTP requests to HTTPS for the supported web endpoint.

HTTPS Only redirects HTTP requests to HTTPS for the supported web endpoint.

Additional instances do not repair a TLS certificate name mismatch. In this case, a browser reports a mismatch between the requested hostname and the site's certificate. “Scale out the App Service plan worker count” would not satisfy that requirement; the supported action is “The custom domain TLS binding and certificate subject names”. Clients validate that the certificate covers the host name presented in the URL.

Deployment slots do not determine the requested custom hostname certificate identity. In this case, a browser reports a mismatch between the requested hostname and the site's certificate. “Change the app deployment slot name” would not satisfy that requirement; the supported action is “The custom domain TLS binding and certificate subject names”. Clients validate that the certificate covers the host name presented in the URL.

VM public IP settings do not repair App Service custom-domain TLS bindings. In this case, a browser reports a mismatch between the requested hostname and the site's certificate. “Modify the public IP allocation of a separate VM” would not satisfy that requirement; the supported action is “The custom domain TLS binding and certificate subject names”. Clients validate that the certificate covers the host name presented in the URL.

hTTPS Only redirects HTTP requests to HTTPS for the supported web endpoint. In this case, an administrator wants all supported app traffic encrypted with modern protocols. “Enable HTTPS Only for the App Service app” would not satisfy that requirement; the supported action is “App Service minimum TLS version and HTTPS enforcement”. A minimum TLS version rejects older client protocol negotiations while HTTPS policy enforces encrypted requests.

A minimum TLS version rejects older client protocol negotiations while HTTPS policy enforces encrypted requests.

domain validation establishes control of the requested hostname before it is accepted by the service. In this case, a public custom domain was added but DNS still resolves to an outdated server. “Complete the App Service custom-domain ownership validation” would not satisfy that requirement; the supported action is “Update the public DNS mapping to the App Service endpoint”. App Service bindings do not automatically modify every external DNS provider's record.

a minimum TLS version rejects older client protocol negotiations while HTTPS policy enforces encrypted requests. In this case, a team plans a domain cutover and wants to verify ownership before routing production traffic. “App Service minimum TLS version and HTTPS enforcement” would not satisfy that requirement; the supported action is “Complete the App Service custom-domain ownership validation”. Domain validation establishes control of the requested hostname before it is accepted by the service.

private Endpoints enable private inbound connectivity, distinct from outbound VNet integration. In this case, a production app needs to test a new build at a separate URL before exchanging it with production. “An App Service private endpoint for inbound access” would not satisfy that requirement; the supported action is “An App Service deployment slot”. Slots provide isolated deployment endpoints that can be swapped with production on supported plans.

the built-in backup feature can capture eligible app content and configuration for recovery. In this case, a production app needs to test a new build at a separate URL before exchanging it with production. “App Service backups where supported by the selected plan” would not satisfy that requirement; the supported action is “An App Service deployment slot”. Slots provide isolated deployment endpoints that can be swapped with production on supported plans.

vNet integration supports outbound access from eligible App Service workers to private resources. In this case, a production app needs to test a new build at a separate URL before exchanging it with production. “App Service virtual network integration” would not satisfy that requirement; the supported action is “An App Service deployment slot”. Slots provide isolated deployment endpoints that can be swapped with production on supported plans.

slot-specific settings remain with their slot rather than swapping with application content. In this case, a hotfix introduced errors after slot swap. “Mark the application setting as a deployment-slot setting” would not satisfy that requirement; the supported action is “Swap back to the previously working deployment slot when available”. A reverse swap can quickly restore the prior deployed version under an appropriate slot configuration.

staging and slot swap reduce risky direct changes to the live endpoint. In this case, a hotfix introduced errors after slot swap. “Deploy to staging, warm and validate, then swap slots” would not satisfy that requirement; the supported action is “Swap back to the previously working deployment slot when available”. A reverse swap can quickly restore the prior deployed version under an appropriate slot configuration.

slots provide isolated deployment endpoints that can be swapped with production on supported plans. In this case, a production app needs an automatic backup schedule and retention settings. “An App Service deployment slot” would not satisfy that requirement; the supported action is “App Service backups where supported by the selected plan”.
