Microsoft AZ-204 Online Questions & Answers

• Question 431:

  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?

  A. Copy blobs to Container2 by using the Put Blob operation of the Blob Service REST API
  B. Create an Event Grid topic that uses the Start-AzureStorageBlobCopy cmdlet
  C. Use AzCopy with the Snapshot switch to copy blobs to Container2
  D. Download the blob to a virtual machine and then upload the blob to Container2
  B. Create an Event Grid topic that uses the Start-AzureStorageBlobCopy cmdlet

  ---

  Explanation

  The Start-AzureStorageBlobCopy cmdlet starts to copy a blob.

  Example 1: Copy a named blob

  C:\PS>Start-AzureStorageBlobCopy -SrcBlob "ContosoPlanning2015" -DestContainer "ContosoArchives" -SrcContainer "ContosoUploads"

  This command starts the copy operation of the blob named ContosoPlanning2015 from the container named ContosoUploads to the container named ContosoArchives.

• Question 432:

  You manage an Azure SQL database that allows for Azure AD authentication.

  You need to make sure that database developers can connect to the SQL database via Microsoft SQL Server Management Studio (SSMS). You also need to make sure the developers use their on-premises Active Directory account for authentication. Your strategy should allow for authentication prompts to be kept to a minimum.

  Which of the following should you implement?

  A. Azure AD token.
  B. Azure Multi-Factor authentication.
  C. Active Directory integrated authentication.
  D. OATH software tokens.
  C. Active Directory integrated authentication.

  ---

  Explanation

  Azure AD can be the initial Azure AD managed domain. Azure AD can also be an on-premises Active Directory Domain Services that is federated with the Azure AD.

  Using an Azure AD identity to connect using SSMS or SSDT

  The following procedures show you how to connect to a SQL database with an Azure AD identity using SQL Server Management Studio or SQL Server Database Tools.

  Active Directory integrated authentication

  Use this method if you are logged in to Windows using your Azure Active Directory credentials from a federated domain.

  1. Start Management Studio or Data Tools and in the Connect to Server (or Connect to Database Engine) dialog box, in the Authentication box, select Active Directory - Integrated. No password is needed or can be entered because your existing credentials will be presented for the connection.

  

  2. Select the Options button, and on the Connection Properties page, in the Connect to database box, type the name of the user database you want to connect to. (The AD domain name or tenant ID" option is only supported for Universal with MFA connection options, otherwise it is greyed out.)

  Explanation

  D:

  CorrelationId: Enables an application to specify a context for the message for the purposes of correlation; for example, reflecting the MessageId of a message that is being replied to.

  F:

  ReplyToSessionId: This value augments the ReplyTo information and specifies which SessionId should be set for the reply when sent to the reply entity.

  Incorrect Answers:

  A, B: DeliveryCount

  Number of deliveries that have been attempted for this message. The count is incremented when a message lock expires, or the message is explicitly abandoned by the receiver. This property is read-only.

  C, E: SequenceNumber

  The sequence number is a unique 64-bit integer assigned to a message as it is accepted and stored by the broker and functions as its true identifier. For partitioned entities, the topmost 16 bits reflect the partition identifier. Sequence numbers monotonically increase and are gapless. They roll over to 0 when the 48-64 bit range is exhausted. This property is read-only.

  You are implementing an application by using Azure Event Grid to push near-real-time information to customers.

  You have the following requirements: You must send events to thousands of customers that include hundreds of various event types.

  The events must be filtered by event type before processing.

  Authentication and authorization must be handled by using Microsoft Entra ID.

  The events must be published to a single endpoint.

  You need to implement Azure Event Grid.

  Solution: Publish events to an event domain. Create a custom topic for each customer.

  Does the solution meet the goal?

  A. Yes
  B. No
  B. No

  ---

  Explanation

  Correct Solution: Publish events to a partner topic. Create an event subscription for each customer.

  Partner Events overview for customers - Azure Event Grid

  Azure Event Grid's Partner Events allows customers to subscribe to events that originate in a registered system using the same mechanism they would use for any other event source on Azure, such as an Azure service. Those registered systems integrate with Event Grid are known as "partners".

  This feature also enables customers to send events to partner systems that support receiving and routing events to customer's solutions/endpoints in their platform.

  Note: Partners

  A partner is a kind of publisher that sends events from its system to make them available to Azure customers. A partner is typically a SaaS or ERP provider that integrates with Azure Event Grid to help customers realize event-driven use cases across platforms. Partners not only can publish events to Azure Event Grid, but they can also receive events from it. These capabilities are enabled through the Partner Events feature.

  Note 2: Why should I use Partner Events?

  You may want to use the Partner Events feature if you've one or more of the following requirements.

  You want to subscribe to events that originate in a partner system and route them to event handlers on Azure or to any application or service with a public endpoint.

  You want to take advantage of the rich set Event Grid's destinations/event handlers that react to events from partners.

  *-> You want to forward events raised by your custom application on Azure, an Azure service, or a Microsoft service to your application or service hosted by the partner system. For example, you may want to send Microsoft Entra ID, Teams, SharePoint, or Azure Storage events to a partner system on which you're a tenant for processing.

  You need a resilient push delivery mechanism with send-retry support and at-least once semantics.

  You want to use Cloud Events 1.0 schema for your events.

  Note 3: Partner topic

  Receive events from a partner

  You receive events from a partner in a partner topic that's' created on your behalf by a partner. Here are the high-level steps to subscribe to events from a partner.

  1. Authorize partner to create a partner topic in a resource group you designate. Authorizations are stored in partner configurations (Azure resources).

  2. Request partner to forward your events from its service to your partner topic. Partner provisions a partner topic in the specified resource group of your Azure subscription.

  3. After the partner creates a partner topic in your Azure subscription and resource group, activate your partner topic.

  4. Subscribe to events by creating one or more event subscriptions on the partner topic.
