   You develop an Azure App Service web app and deploy to a production environment. You enable Application Insights for the web app. The web app is throwing multiple exceptions in the environment. You need to examine the state of the source code and variables when the exceptions are thrown. Which Application Insights feature should you configure?

   • ASmart detection
   • BProfiler
   • CSnapshot Debugger
   • DStandard test

   Show answer

   Answer: C

   Explanation

   C. Snapshot Debugger The Snapshot Debugger is an Application Insights feature that allows you to examine the state of the source code and variables when an exception is thrown. It captures a snapshot of the call stack, local variables, and object state at the time of the exception. With this feature, you can easily identify the cause of the exception and fix the issue.

   Explanation

   Correct. BLOCK 0 means that we will wait infinitely (timeout 0 means it will never expire) for new items in a stream. $ ID means that we will receive only new messages, starting from the time we started listening https://redis.io/docs/data-types/streams-tutorial/#listening-for-new-items-with-xread

   Select 2

   You develop an ASP.NET Core app that uses Azure App Configuration. You also create an App Configuration containing 100 settings. The app must meet the following requirements: • Ensure the consistency of all configuration data when changes to individual settings occur. • Handle configuration data changes dynamically without causing the application to restart. • Reduce the overall number of requests made to App Configuration APIs. You must implement dynamic configuration updates in the app. What are two ways to achieve this goal? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

   • ACreate and register a sentinel key in the App Configuration store. Set the refreshAll parameter of the Register method to true.
   • BIncrease the App Configuration cache expiration from the default value.
   • CDecrease the App Configuration cache expiration from the default value.
   • DCreate and configure Azure Key Vault. Implement the Azure Key Vault configuration provider.
   • ERegister all keys in the App Configuration store. Set the refreshAll parameter of the Register method to false.
   • FCreate and implement environment variables for each App Configuration store setting.

   Show answer

   Answer: AB

   Explanation

   Quotes from the reference below: "A sentinel key is a key that you update after you complete the change of all other keys. Your app monitors the sentinel key. When a change is detected, your app refreshes all configuration values. This approach helps to ensure the consistency of configuration in your app and reduces the overall number of requests made to your App Configuration store, compared to monitoring all keys for changes." "You can add a call to the refreshOptions.SetCacheExpiration method to specify the minimum time between configuration refreshes. In this example, you use the default value of 30 seconds. Adjust to a higher value if you need to reduce the number of requests made to your App Configuration store."

5. Question 365 · 462 in bank

   HOTSPOT - You develop and deploy an Azure App Service web app that connects to Azure Cache for Redis as a content cache. All resources have been deployed to the East US 2 region. The security team requires the following audit information from Azure Cache for Redis: • The number of Redis client connections from an associated IP address. • Redis operations completed on the content cache. • The location (region) in which the Azure Cach3e for Redis instance was accessed. The audit information must be captured and analyzed by a security team application deployed to the Central US region. You need to log information on all client connections to the cache. Which configuration values should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

   You develop and deploy a web app to Azure App Service. The Azure App Service uses a Basic plan in a single region. Users report that the web app is responding slow. You must capture the complete call stack to help identify performance issues in the code. Call stack data must be correlated across app instances. You must minimize cost and impact to users on the web app. You need to capture the telemetry. Which three actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

   • ARestart all apps in the App Service plan.
   • BEnable Application Insights site extensions.
   • CUpgrade the Azure App Service plan to Premium.
   • DEnable Profiler.
   • EEnable the Always On setting for the app service.
   • FEnable Snapshot debugger.
   • GEnable remote debugging.

   Show answer

   Answer: BDE

   Explanation

   B E F B. Enable Application Insights site extensions: Application Insights provides end-to-end insights into the web app's performance and usage. Enabling the Application Insights site extension allows you to collect telemetry data, including call stack traces, to help identify performance issues in the code. E. Enable the Always On setting for the app service: Enabling the Always On setting ensures that the web app is always running, even when there is no traffic. This reduces the impact of cold starts and improves the web app's response time. F. Enable Snapshot debugger: Enabling Snapshot debugger allows you to capture the complete call stack and local variables for an exception that occurred in the web app. This helps to identify performance issues and diagnose issues in the code.

8. Question 368 · 462 in bank

   You are building an application to track cell towers that are available to phones in near real time. A phone will send information to the application by using the Azure Web PubSub service. The data will be processed by using an Azure Functions app. Traffic will be transmitted by using a content delivery network (CDN). The Azure function must be protected against misconfigured or unauthorized invocations. You need to ensure that the CDN allows for the Azure function protection. Which HTTP header should be on the allowed list?

   • AAuthorization
   • BWebHook-Request-Callback
   • CResource
   • DWebHook-Request-Origin

   Show answer

   Answer: D

   Explanation

   Most likely, it's A, since they ask about "Unauthorized protection" instead of "Abuse Protection", which are both supported by underlying "CloudEvents HTTP protocols" (web-hooks). https://github.com/cloudevents/spec/blob/v1.0/http-webhook.md#4-abuse-protection So, if we read attentively about Abuse Protection / webhook-request-origin, we can find this excerpt: "It is important to understand is that the handshake does not aim to establish an authentication or authorization context. It only serves to protect the sender from being told to a push to a destination that is not expecting the traffic. While this specification mandates use of an authorization model, this mandate is not sufficient to protect any arbitrary website from unwanted traffic if that website doesn't implement access control and therefore ignores the Authorization header." And this is Authorization header description in this protocol: https://github.com/cloudevents/spec/blob/v1.0/http-webhook.md#3-authorization

   You are developing an Azure App Service web app. The web app must securely store session information in Azure Redis Cache. You need to connect the web app to Azure Redis Cache. Which three Azure Redis Cache properties should you use? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

   • AAccess key
   • BSSL port
   • CSubscription name
   • DLocation
   • EHost name
   • FSubscription id

   Show answer

   Answer: ABE

   Explanation

   When connecting a web app to Azure Redis Cache, you need to specify certain properties. Here are three Azure Redis Cache properties you should use: Hostname: This property represents the fully qualified domain name (FQDN) or the endpoint URL of the Azure Redis Cache instance. It is used to establish a connection between the web app and the cache. The hostname typically follows the format yourcache.redis.cache.windows.net. Port: This property specifies the port number used for communication with the Azure Redis Cache instance. The default port for Redis is 6379, but you can configure it differently if needed. Access key: This property is the primary or secondary access key for the Azure Redis Cache instance.
