Question 380An IIS app uses a certificate bound to a specific machine store and fails after moving to an App Service deployment slot. How can administrators make this correction durable through future changes? Document statelessness assumptions and regression-test session behavior before increasing web-tier scale. Include PaaS compatibility checks and dependency inventory in IIS-to-Azure workload selection. Inventory certificate expiration and bindings across each deployment slot during IIS modernization. Establish pre-cutover health criteria, traffic monitoring and a rehearsed rollback for all IIS-to-Azure transitions. ExplanationCorrect Answer C:Inventory certificate expiration and bindings across each deployment slot during IIS modernization. This preventive control maintains the intended protection because tLS bindings and private key custody in PaaS differ from a local Windows certificate store and must be provisioned explicitly. The initial action remains: Move the required certificate and application configuration through supported Azure App Service certificate and binding mechanisms. Other Answers A:Scaled-out or rescheduled PaaS instances cannot guarantee that consecutive requests share the same local filesystem or process memory. The lasting safeguard is to inventory certificate expiration and bindings across each deployment slot during IIS modernization. B:PaaS web hosting has a different runtime and operating-system access boundary than an administrator-controlled IIS VM. The lasting safeguard is to inventory certificate expiration and bindings across each deployment slot during IIS modernization. D:A web deployment's application health depends on identity, DNS and back-end readiness; a DNS update is not evidence that the workload is healthy. A more direct preventive measure is to inventory certificate expiration and bindings across each deployment slot during IIS modernization.
Question 381A migrated IIS web app still connects to a SQL database using a password embedded in web.config, and that secret leaks in a build log. What should the administrator change first to resolve the stated issue? Move the required certificate and application configuration through supported Azure App Service certificate and binding mechanisms. Run application compatibility assessment and refactor unsupported Windows-specific dependencies before selecting the Azure App Service target. Stage the deployment, complete smoke tests and use a controlled traffic-switch or slot-swap plan with rollback. Replace the embedded database secret with an appropriate managed identity or protected secret reference and enforce SQL authorization. ExplanationCorrect Answer D:Replace the embedded database secret with an appropriate managed identity or protected secret reference and enforce SQL authorization. This resolves the observed failure because modern Azure identity and secret-management controls can avoid shipping reusable plaintext database credentials with deployed application code. A suitable acceptance check is: Verify access using the intended app identity and confirm unauthorized identities are denied without exposing secrets in deployment logs. Other Answers A:TLS bindings and private key custody in PaaS differ from a local Windows certificate store and must be provisioned explicitly. This failure calls for a decision to replace the embedded database secret with an appropriate managed identity or protected secret reference and enforce SQL authorization. B:PaaS web hosting has a different runtime and operating-system access boundary than an administrator-controlled IIS VM. The corrective action for this requirement is to replace the embedded database secret with an appropriate managed identity or protected secret reference and enforce SQL authorization. C:A web deployment's application health depends on identity, DNS and back-end readiness; a DNS update is not evidence that the workload is healthy. A more relevant action is to replace the embedded database secret with an appropriate managed identity or protected secret reference and enforce SQL authorization.

Reducing this risk requires a practice to require secret scanning and identity-based access testing in the web application deployment pipeline.
Question 385An IIS application stores shopping-cart session state on local disk and loses users' sessions when its new Azure service scales to two instances. What is the most appropriate action given the observed constraints? Replace the embedded database secret with an appropriate managed identity or protected secret reference and enforce SQL authorization. Stage the deployment, complete smoke tests and use a controlled traffic-switch or slot-swap plan with rollback. Externalize session and mutable application state to a supported shared service rather than relying on one web-worker disk. Run application compatibility assessment and refactor unsupported Windows-specific dependencies before selecting the Azure App Service target. ExplanationCorrect Answer C:Externalize session and mutable application state to a supported shared service rather than relying on one web-worker disk. This resolves the observed failure because scaled-out or rescheduled PaaS instances cannot guarantee that consecutive requests share the same local filesystem or process memory. A suitable acceptance check is: Load-balance test clients across multiple instances and verify session persistence and correct order state.
