Question 370 A team expects every App Service pricing tier to provide unlimited deployment slots. What must be checked? The storage account's blob tier The Azure availability zone count alone The selected plan tier's deployment-slot support and limits The length of the custom hostname Explanation Correct Answer C:Staging slots are plan features whose availability depends on the chosen tier. Incorrect Answers A:Blob tiers do not enable web deployment slots. B:Zones do not establish slot entitlement. D:Hostname length doesn't grant extra slots.
Question 371 A website has frequent independent HTTP requests and needs more concurrent serving capacity. Which App Service scaling direction adds workers? Enable resource locks on the web app Scale out the App Service plan to additional instances Increase the App Service plan tier but keep the same worker-instance count Move the source code to a new branch without deployment Explanation Correct Answer B:More workers distribute HTTP application load. Incorrect Answers A:Locks restrict management writes, not runtime capacity. C:Scale up enlarges individual workers; scale out adds instances for concurrent requests. D:A branch doesn't create running instances.
Question 372 An App Service app needs more memory per worker rather than more workers. Which action is a scale-up? Create three more deployment slots Add three Azure tags to the app Create another public IP for an unrelated VM Move the App Service plan to a suitable larger tier or size Explanation Correct Answer D:Scale-up increases the capacity available to each instance. Incorrect Answers A:Slots stage releases, not a direct per-instance memory upgrade. B:Tags have no impact on allocated memory. C:That does not modify the App Service plan's workers.
Question 373 A team has two web apps hosted in one App Service plan. What distinction is important? The plan defines shared compute resources while each app has its own application configuration Assume an App Service app's name alone defines compute capacity independent of its plan Each app necessarily has its own independent VM cluster regardless of plan Two apps in a plan must share the same Azure subscription owner password Explanation Correct Answer A:Multiple apps can share the plan's worker capacity. Incorrect Answers B:An App Service plan controls the hosting resources for apps assigned to it. C:Apps in one plan can contend for shared workers. D:App identity and permissions remain separately manageable.
Question 374 Marketing requires a company-branded hostname for a managed web app. What integration should developers configure? An Azure Data Box shipment An Azure Policy initiative named after the website A VM availability set with the website name An App Service custom domain with appropriate DNS validation Explanation Correct Answer D:The platform can serve the app under a verified custom hostname. Incorrect Answers A:Offline data transfer is irrelevant to web addressing. B:Policy does not configure DNS domain ownership. C:Fault-domain placement doesn't assign an HTTP hostname.
Question 375 An app uses a custom HTTPS hostname and the team wants encrypted browser connections. What must be considered? A VM's temporary disk encryption switch A storage account with a cold tier A resource group display name containing 'secure' A supported TLS certificate and hostname binding or managed certificate option Explanation Correct Answer D:HTTPS requires a valid certificate presented for that hostname. Incorrect Answers A:An unrelated VM storage option cannot supply the App Service certificate. B:Blob access tier does not encrypt the browser TLS session. C:Administrative naming cannot establish TLS.
Question 376 A web app returns 500 errors after an update. Which first diagnostic evidence is useful? Subscription billing contact information Azure region-pair names App Service application and HTTP logs for the failing deployment A resource group tag naming convention Explanation Correct Answer C:Request and application diagnostics can reveal the observed failure path. Incorrect Answers A:A billing email does not explain an application exception. B:Region metadata doesn't show the failing request. D:Tags don't contain request stack traces.
Question 377 A small internal web app receives almost no traffic but runs on a paid App Service plan. What cost assumption is risky? Assuming storage bandwidth contributes to cost Assuming scale-down options might reduce baseline spend Assuming web app settings affect application behavior Assuming zero web requests always means zero paid plan charges Explanation Correct Answer D:Provisioned App Service plan capacity may incur costs even when idle. Incorrect Answers A:Storage transfers can contribute charges. B:Right-sizing can be a legitimate cost control. C:They can; the cost concern is paid capacity.
Question 378 A process only needs to react when a blob is added and finish a short transformation. Which compute model is a good fit? Use a permanently running VM for a function that should execute on events A permanent dedicated Windows VM solely to poll each second An Azure Virtual Desktop session An Azure Function with an appropriate storage event trigger Explanation Correct Answer D:Functions support short event-driven code without a dedicated long-running VM. Incorrect Answers A:A VM can host code, but it does not automatically provide the event-triggered Azure Functions execution model. B:This increases operations and idle capacity for an intermittent event. C:An interactive desktop is not a blob event handler.
Question 379 A lightweight serverless endpoint receives HTTPS requests and executes a short piece of code. Which Azure capability directly supports this? Azure Backup restore point Azure Firewall as the application runtime A storage account lifecycle rule An HTTP-triggered Azure Function Explanation Correct Answer D:The function executes application code in response to incoming HTTP requests. Incorrect Answers A:A restore point cannot handle a live API request. B:A firewall forwards or filters traffic but doesn't execute business code. C:Lifecycle management moves objects rather than executing API logic.
Question 380 An infrequently used serverless function runs a few times daily. Which billing distinction should designers consider? Every function always costs the same as one dedicated VM 24 hours a day Function calls are always free regardless of quotas Assume function invocation count is irrelevant in a consumption-based plan Execution-based billing on eligible serverless plans, subject to plan details Explanation Correct Answer D:Suitable consumption options charge based on executions and resource usage rather than a permanently assigned VM. Incorrect Answers A:Billing varies by selected Functions hosting plan. B:Free grants or consumption charges depend on plan and usage. C:For applicable plans, executions and execution resource consumption contribute to function charges.
