1. Question 411 · 462 in bank

   DRAG DROP - You are developing an Azure solution to collect inventory data from thousands of stores located around the world. Each store location will send the inventory data hourly to an Azure Blob storage account for processing. The solution must meet the following requirements: ✑ Begin processing when data is saved to Azure Blob storage. ✑ Filter data based on store location information. ✑ Trigger an Azure Logic App to process the data for output to Azure Cosmos DB. ✑ Enable high availability and geographic distribution. ✑ Allow 24-hours for retries. ✑ Implement an exponential back off data processing. You need to configure the solution. What should you implement? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Select and Place:

   Answer: See figure below

   Explanation

   I think that the right solution should be: Source -> blob storage Receiver -> event grid Handler -> logic app Because: 1)the source of the event, which means WHO has created the event and who is publishing this event, is the Blob Storage 2)The receiver of this event, which means who should receive this event, is the Event Grid. In the event Grid we can create Topic. Topic is where all publishers write messages --> so the Blob Storage write into a topic which is inside an Event Grid. 3)Handler of this event, which means who should handle this event, is the Logic App by creating a subscription in the event grid and connecting the Logic App to that subscription.

6. Question 416 · 462 in bank

   You are developing an e-commerce solution that uses a microservice architecture. You need to design a communication backplane for communicating transactional messages between various parts of the solution. Messages must be communicated in first-in-first-out (FIFO) order. What should you use?

   • AAzure Storage Queue
   • BAzure Event Hub
   • CAzure Service Bus
   • DAzure Event Grid

   Show answer

   Answer: C

   Explanation

   Choose Service Bus queues if: You need an At-Most-Once delivery guarantee. You need a FIFO guarantee. You need to group messages into transactions. You want to receive messages without polling the queue. You need to provide a role-based access model to the queues. You need to handle messages larger than 64 KB but less than 256 KB. Your queue size will not grow larger than 80 GB. You would like to be able to publish and consume batches of messages. Queue storage isn't quite as feature-rich, but if you don't need any of those features, it can be a simpler choice. In addition, it's the best solution if your app has any of the following requirements. Choose Queue storage if: You need an audit trail of all messages that pass through the queue. You expect the queue to exceed 80 GB in size. You want to track progress for processing a message inside of the queue.

7. Question 417 · 462 in bank

   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 blobs to Archive tier after they have not been modified within 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. NOTE: Each correct selection is worth one point. Select and Place:

8. Question 418 · 462 in bank

   Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You are developing an Azure Service application that processes queue data when it receives a message from a mobile application. Messages may not be sent to the service consistently. You have the following requirements: ✑ Queue size must not grow larger than 80 gigabytes (GB). ✑ Use first-in-first-out (FIFO) ordering of messages. ✑ Minimize Azure costs. You need to implement the messaging solution. Solution: Use the .Net API to add a message to an Azure Service Bus Queue from the mobile application. Create an Azure Function App that uses an Azure Service Bus Queue trigger. Does the solution meet the goal?

   • AYes
   • BNo

   Show answer

   Answer: A

   Explanation

   No. Service Bus Queue is FIFO. Not Storage Queue. I hit the upvote button by mistake, instead of reply. So don't assume someone upvoted your answer :)

   Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You are developing an Azure solution to collect point-of-sale (POS) device data from 2,000 stores located throughout the world. A single device can produce 2 megabytes (MB) of data every 24 hours. Each store location has one to five devices that send data. You must store the device data in Azure Blob storage. Device data must be correlated based on a device identifier. Additional stores are expected to open in the future. You need to implement a solution to receive the device data. Solution: Provision an Azure Notification Hub. Register all devices with the hub. Does the solution meet the goal?

   • AYes
   • BNo

   Show answer

   Answer: B

   Explanation

   Azure Event Hub is for telemetry and distributed data broadcasting, while Azure Service Bus can be used for order processing and financial transactions. What is clearly specified in the statement: "You are developing an Azure solution to collect point-of-sale (POS) device data from 2,000 stores ...". It's Service Bus
