4. Question 434 · 462 in bank

   HOTSPOT - You are developing a solution by using the Azure Event Hubs SDK. You create a standard Azure Event Hub with 16 partitions. You implement eight event processor clients. You must balance the load dynamically when an event processor client fails. When an event processor client fails, another event processor must continue processing from the exact point at which the failure occurred. All events must be aggregate and upload to an Azure Blob storage account. You need to implement event processing recovery for the solution. Which SDK features should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

   Explanation

   This is a really stupid and confusing question but I think it’s checkpoint to ensure marking and offset to mark… This ref says: ”Checkpointing is a process by which readers mark or commit their position within a partition event sequence.” https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-features#checkpointing But this ref here says: ”Consumers also engage in checkpointing. Through this process, subscribers use offsets to mark their position within a partition event sequence. An offset is a placeholder that works like a bookmark to identify the last event that the consumer read.” https://learn.microsoft.com/en-us/azure/architecture/reference-architectures/event-hubs/partitioning-in-event-hubs-and-kafka#dataflow

   Explanation

   I just tested it on Azure. The documentation and the examtopics answer are wrong, it says: Usage Policy sections: inbound, outbound, on-error here: https://learn.microsoft.com/en-us/azure/api-management/mock-response-policy But if I put inside I get an error: Error in element 'mock-response' on line 18, column 10: Policy is not allowed in this section The correct place is beyond any doubt. So the answer is: 1. mock-response 2. inbound 3. 200

   Select 3

   You are developing several Azure API Management (APIM) hosted APIs. You must inspect request processing of the APIs in APIM. Requests to APIM by using a REST client must also be included. The request inspection must include the following information: • requests APIM sent to the API backend and the response it received • policies applied to the response before sending back to the caller • errors that occurred during the processing of the request and the policies applied to the errors • original request APIM received from the caller and the policies applied to the request You need to inspect the APIs. Which three actions should you do? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

   • AEnable the Allow tracing setting for the subscription used to inspect the API.
   • BAdd the Ocp-Apim-Trace header value to the API call whit a value set to true.
   • CAdd the Ocp-Apim-Subscription-Key header value to the key for a subscription that allows access to the API.
   • DCreate and configure a custom policy. Apply the policy to the inbound policy section with a global scope.
   • ECreate and configure a custom policy. Apply the policy to the outbound policy section with an API scope.

   Show answer

   Answer: ABC

   Explanation

   From: https://learn.microsoft.com/en-us/azure/api-management/api-management-howto-api-inspector -To trace request processing, you must enable the Allow tracing setting for the subscription used to debug your API. -When making requests to API Management using curl, a REST client such as Postman, or a client app, enable tracing by adding the following request headers: Ocp-Apim-Trace - set value to true Ocp-Apim-Subscription-Key - set value to the key for a tracing-enabled subscription that allows access to the API

   Explanation

   Box 1: No - The QueueDescription.LockDuration property gets or sets the duration of a peek lock; that is, the amount of time that the message is locked for other receivers. The maximum value for LockDuration is 5 minutes; the default value is 1 minute. Box 2: Yes - You can peek at the message in the front of a queue without removing it from the queue by calling the PeekMessage method. Box 3: Yes - Reference: https://docs.microsoft.com/en-us/azure/storage/queues/storage-dotnet-how-to-use-queues https://docs.microsoft.com/en-us/dotnet/api/microsoft.servicebus.messaging.queuedescription.lockduration

10. Question 440 · 462 in bank

    You are developing several Azure API Management (APIM) hosted APIs. You must make several minor and non-breaking changes to one of the APIs. The API changes include the following requirements: • Must not disrupt callers of the API. • Enable roll back if you find issues. • Documented to enable developers to understand what is new. • Tested before publishing. You need to update the API. What should you do?

    • AConfigure and apply header-based versioning.
    • BCreate and publish a product.
    • CConfigure and apply a custom policy.
    • DAdd a new revision to the API.
    • EConfigure and apply query string-based versioning.

    Show answer

    Answer: D

    Explanation

    D is correct: In Azure API Management, use revisions to make non-breaking API changes so you can model and test changes safely. When ready, you can make a revision current and replace your current API. https://learn.microsoft.com/en-us/azure/api-management/api-management-get-started-revise-api?tabs=azure-portal
