• Question 166:

  You are developing an Azure messaging solution.

  You need to ensure that the solution meets the following requirements:

  1. Provide transactional support.

  2. Provide duplicate detection.

  3. Store the messages for an unlimited period of time.

  Which two technologies will meet the requirements? Each correct answer presents a complete solution.

  A. Azure Service Bus Topic
  B. Azure Service Bus Queue
  C. Azure Storage Queue
  D. Azure Event Hub
  A. Azure Service Bus Topic
  B. Azure Service Bus Queue

  ---

  Explanation

  The Azure Service Bus Queue and Topic has duplicate detection. Enabling duplicate detection helps keep track of the application-controlled MessageId of all messages sent into a queue or topic during a specified time window.

  Incorrect Answers:

  C: There is just no mechanism that can query a Storage queue and find out if a message with the same contents is already there or was there before.

  D: Azure Event Hub does not have duplicate detection

• Question 167:

  DRAG DROP

  A company backs up all manufacturing data to Azure Blob Storage. Admins move blobs from hot storage to archive tier storage every month.

  You must automatically move blocks to Archive tier after they have not been accessed for 180 days. The path for any item that is not archived must be placed in an existing queue. This operation must be performed automatically once a month. You set the value of TierAgeInDays to 180.

  How should you configure the Logic App? To answer, drag the appropriate triggers or action blocks to the correct trigger or action slots. Each trigger or action block may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

  Box 1: Azure Blob index tags - As datasets get larger, finding a specific object in a sea of data can be difficult. Blob index tags provide data management and discovery capabilities by using key- value index tag attributes. You can categorize and find objects within a single container or across all containers in your storage account. As data requirements change, objects can be dynamically categorized by updating their index tags. Objects can remain in-place with their current container organization.

  Box 2: Azure Cognitive Search - Only index tags are automatically indexed and made searchable by the native Blob Storage service. Metadata can't be natively indexed or searched. You must use a separate service such as Azure Search.

  Azure Cognitive Search is the only cloud search service with built-in AI capabilities that enrich all types of information to help you identify and explore relevant content at scale. Use cognitive skills for vision, language, and speech, or use custom machine learning models to uncover insights from all types of content.

• Question 170:

  You are developing an application that uses Azure Blob storage.

  The application must read the transaction logs of all the changes that occur to the blobs and the blob metadata in the storage account for auditing purposes. The changes must be in the order in which they occurred, include only create, update, delete, and copy operations and be retained for compliance reasons.

  You need to process the transaction logs asynchronously.

  What should you do?

  A. Process all Azure Blob storage events by using Azure Event Grid with a subscriber Azure Function app.
  B. Enable the change feed on the storage account and process all changes for available events.
  C. Process all Azure Storage Analytics logs for successful blob events.
  D. Use the Azure Monitor HTTP Data Collector API and scan the request body for successful blob events.
  B. Enable the change feed on the storage account and process all changes for available events.

  Explanation

  Change feed support in Azure Blob Storage

  The purpose of the change feed is to provide transaction logs of all the changes that occur to the blobs and the blob metadata in your storage account. The change feed provides ordered, guaranteed, durable, immutable, read-only log of these changes. Client applications can read these logs at any time, either in streaming or in batch mode. The change feed enables you to build efficient and scalable solutions that process change events that occur in your Blob Storage account at a low cost.
