Question 1

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 Event Grid. Configure event filtering to evaluate the device identifier. Does the solution meet the goal?

Question Analysis

Core concept: This question tests choosing the correct Azure ingestion service for device telemetry at scale and understanding the difference between Event Grid (event notification/routing) and services designed for high-throughput device-to-cloud data ingestion (IoT Hub/Event Hubs) before persisting to Blob storage. Why the answer is correct: Event Grid is primarily an event routing service for discrete events (e.g., “blob created”, “resource changed”) and is not intended to be the primary endpoint for continuous device telemetry uploads from thousands of POS devices. While Event Grid supports filtering on event metadata, it does not provide the device connectivity, ingestion semantics, or telemetry-oriented features needed to reliably receive and buffer device data streams at scale. A more appropriate pattern is to ingest device messages via Azure IoT Hub (or Event Hubs for non-IoT scenarios), then use routing/Stream Analytics/Functions to write to Blob Storage with partitioning by device identifier. Key features / configurations: - Azure Event Grid: event notification, push delivery to handlers, filtering on event subject/type/data fields, at-least-once delivery for events. - Azure IoT Hub: per-device identity, device authentication, device-to-cloud telemetry ingestion, message routing to storage/endpoints. - Azure Event Hubs: high-throughput event ingestion, partitions/consumer groups; typically paired with processors to persist to Blob. - Correlation by device identifier: use IoT Hub device ID or message properties; write to Blob paths like /deviceId=/yyyy=/mm=/dd= for efficient organization. Common misconceptions: - Assuming Event Grid is a general-purpose ingestion endpoint for arbitrary device payloads; it is mainly for routing events emitted by Azure services or custom publishers, not for direct device telemetry at scale. - Confusing “filtering” with “correlation/storage partitioning”; filtering only decides where events go, it doesn’t inherently organize or persist data by device ID. - Overlooking device management needs (identity, authentication, throttling) that IoT Hub provides. Exam tips: - Use Event Grid for reactive workflows and notifications (resource events, blob created, etc.), not for primary telemetry ingestion. - For many devices sending data: prefer IoT Hub (device identity + telemetry) or Event Hubs (stream ingestion). - If the requirement includes “correlate by device identifier,” think message properties + downstream partitioning/routing to storage. - When the destination is Blob Storage, expect an intermediate ingestion service plus a processor (Functions/Stream Analytics) or built-in routing (IoT Hub routing).

Question 2

You develop Azure solutions. You must connect to a No-SQL globally-distributed database by using the .NET API. You need to create an object to configure and execute requests in the database. Which code segment should you use?

Question 3

DRAG DROP - You develop a web app that uses the tier D1 app service plan by using the Web Apps feature of Microsoft Azure App Service. Spikes in traffic have caused increases in page load times.

Question 6

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?

Question 7

You develop an app that allows users to upload photos and videos to Azure storage. The app uses a storage REST API call to upload the media to a blob storage account named Account1. You have blob storage containers named Container1 and Container2. Uploading of videos occurs on an irregular basis. You need to copy specific blobs from Container1 to Container2 when a new video is uploaded. What should you do?

Question 8

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 develop an HTTP triggered Azure Function app to process Azure Storage blob data. The app is triggered using an output binding on the blob. The app continues to time out after four minutes. The app must process the blob data. You need to ensure the app does not time out and processes the blob data. Solution: Configure the app to use an App Service hosting plan and enable the Always On setting. Does the solution meet the goal?

You plan to assign users one of the following permission levels for the website: admin, normal, and reader. A user's Azure AD group membership must be used to determine the permission level. You need to configure authorization. Solution: ✑ Create a new Azure AD application. In the application's manifest, define application roles that match the required permission levels for the application. ✑ Assign the appropriate Azure AD group to each role. In the website, use the value of the roles claim from the JWT for the user to determine permissions. Does the solution meet the goal?
