The updated exam now includes a section on Azure App Service, which is a fully managed platform for building, deploying, and scaling web apps, mobile backends, and RESTful APIs.
New Sections:
Section: Azure Event Hubs
Question: You need to enable state persistence for the event processor client while using the Azure Event Hubs SDK to read from multiple partitions. Which object should you use?
Answer: BlobContainerClient
Explanation: To enable state persistence for the event processor client, you should use the BlobContainerClient object in the Azure.Storage.Blobs NuGet package. This allows you to store checkpoints and other metadata in an Azure Blob Storage container, which can be used to track progress and recover from failures.
Question: You are developing an application to ingest and process events using the Azure Event Hubs library for .NET. Which API class should you use to publish events in batches?
Answer: EventHubProducerClient
Explanation: To publish events in batches using the Azure Event Hubs library for .NET, you should use the EventHubProducerClient API class. This allows you to efficiently send multiple events at once, reducing latency and improving performance.
Section: Azure Monitor
Question: You must edit and run queries using the data collected by Azure Monitor. Which two data types should you use?
Answer: Metrics and Logs
Explanation: Azure Monitor provides two primary data types for monitoring and analysis: Metrics and Logs. Metrics provide a numerical view of performance data, while Logs provide a detailed record of events and activities. By using both types of data, you can get a comprehensive view of your app's performance and identify areas for improvement.
Question: You are monitoring app performance by using Azure Monitor. You need to identify the amount of time required for the app to access an Azure Redis cache and how it contributes to the app's response time. Which API method should you use?
Answer: TrackDependency
Explanation: To track the amount of time required for the app to access an Azure Redis cache, you should use the TrackDependency API method in the Application Insights SDK. This allows you to monitor dependencies on external resources and services, such as Redis caches, and identify performance bottlenecks that may be impacting your app's response time.
Section: Azure Event Grid
Question: You need to configure the permission needed to send events to an Azure Event Grid topic. Which permission should you configure?
Recommended by LinkedIn
Answer: Microsoft.EventGrid/systemTopics/Write
Explanation: To send events to an Azure Event Grid topic, you should configure the Microsoft.EventGrid/systemTopics/Write permission on the Event Grid. This allows you to write events to the topic and notify subscribers of new events as they occur.
Question: You are developing an Azure Function app to process a custom Azure Event Grid topic. Which event schema property should you use to enable subscribers to filter and route events for the custom topic?
Answer: eventType
Explanation: To enable subscribers to filter and route events for a custom Azure Event Grid topic, you should use the eventType property in the event schema. This allows subscribers to specify the types of events they are interested in and filter out events that are not relevant to their needs.
Section: Azure Functions
Question 1:
