Microsoft Microsoft Certifications AZ-204 Questions & Answers

• Question 151:

  HOTSPOT

  You are validating the configuration of an Azure Search indexer.

  The service has been configured with an indexer that uses the Import Data option. The index is configured using options as shown in the Index Configuration exhibit. (Click the Index Configuration tab.)

  

  You use an Azure table as the data source for the import operation. The table contains three records with item inventory data that matches the fields in the Storage data exhibit. These records were imported when the index was created. (Click the Storage Data tab.) When users search with no filter, all three records are displayed.

  

  When users search for items by description, Search explorer returns no records. The Search Explorer exhibit shows the query and results for a test. In the test, a user is trying to search for all items in the table that have a description that contains the word bag. (Click the Search Explorer tab.)

  

  You need to resolve the issue.

  For each of the following statements, select Yes if the statement is true. Otherwise, select No.

  NOTE: Each correct selection is worth one point.

  Hot Area:

  

  Correct Answer:

  

  Box 1: Yes

  The ItemDescription field in not searchable.

  Box 2: No

  The ItemDescription field in not searchable, but we would need to recreate the index.

  Box 3: Yes

  An indexer in Azure Search is a crawler that extracts searchable data and metadata from an external Azure data source and populates an index based on field-to-field mappings between the index and your data source. This approach is

  sometimes referred to as a 'pull model' because the service pulls data in without you having to write any code that adds data to an index.

  Box 4: No

  You need to configure Azure CDN for the Shipping web site.

  Which configuration options should you use? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  Hot Area:

  

  Correct Answer:

  

  Scenario: Shipping website Use Azure Content Delivery Network (CDN) and ensure maximum performance for dynamic content while minimizing latency and costs. Tier: Standard Profile: Akamai Optimization: Dynamic site acceleration Dynamic site acceleration (DSA) is available for Azure CDN Standard from Akamai, Azure CDN Standard from Verizon, and Azure CDN Premium from Verizon profiles. DSA includes various techniques that benefit the latency and performance of dynamic content. Techniques include route and network optimization, TCP optimization, and more. You can use this optimization to accelerate a web app that includes numerous responses that aren't cacheable. Examples are search results, checkout transactions, or real-time data. You can continue to use core Azure CDN caching capabilities for static data.

  You need to correct the VM issues.

  Which tools should you use? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  Hot Area:

  

  Correct Answer:

  

  Backup and Restore: Azure Backup

  Scenario: The VM is critical and has not been backed up in the past. The VM must enable a quick restore from a 7-day snapshot to include in-place restore of disks in case of failure.

  In-Place restore of disks in IaaS VMs is a feature of Azure Backup.

  Performance: Accelerated Networking

  Scenario: The VM shows high network latency, jitter, and high CPU utilization.

  Accelerated networking enables single root I/O virtualization (SR-IOV) to a VM, greatly improving its networking performance. This high-performance path bypasses the host from the datapath, reducing latency, jitter, and CPU utilization, for

  use with the most demanding network workloads on supported VM types.

  You are building a website to access project data related to teams within your organization. The website does not allow anonymous access. Authentication is performed using an Azure Active Directory (Azure AD) app named internal.

  The website has the following authentication requirements:

  1.

  Azure AD users must be able to login to the website.

  2.

  Personalization of the website must be based on membership in Active Directory groups.

  You need to configure the application's manifest to meet the authentication requirements.

  Enable group membership claims by changing the groupMembershipClaim

  The valid values are:

  "All"

  "SecurityGroup"

  "DistributionList"

  "DirectoryRole"

  Box 2: oauth2Permissions

  Scenario: Azure AD users must be able to login to the website.

  oauth2Permissions specifies the collection of OAuth 2.0 permission scopes that the web API (resource) app exposes to client apps. These permission scopes may be granted to client apps during consent.

  Incorrect Answers:

  oauth2AllowImplicitFlow. oauth2AllowImplicitFlow specifies whether this web app can request OAuth2.0 implicit flow access tokens. The default is false. This flag is used for browser-based apps, like Javascript single-page apps.

• Question 159:

  HOTSPOT

  You are developing an application that use an Azure blob named data to store application data. The application creates blob snapshots to allow application state to be reverted to an earlier state. The Azure storage account has soft deleted

  enabled.

  The system performs the following operations in order:

  1.

  The blob is updated

  2.

  Snapshot 1 is created.

  3.

  Snapshot 2 is created.

  4.

  Snapshot 1 is deleted.
