  You develop an ASP.NET Core MVC application. You configure the application to track webpages and custom events.

  You need to identify trends in application usage.

  Which Azure Application Insights Usage Analysis features should you use? To answer, drag the appropriate features to the correct requirements. Each feature 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:

  

  Correct Answer:

  

  Box 1: Users

  Box 2: Impact One way to think of Impact is as the ultimate tool for settling arguments with someone on your team about how slowness in some aspect of your site is affecting whether users stick around. While users may tolerate a certain amount of slowness, Impact gives you insight into how best to balance optimization and performance to maximize user conversion.

  Box 3: Retention

  The retention feature in Azure Application Insights helps you analyze how many users return to your app, and how often they perform particular tasks or achieve goals. For example, if you run a game site, you could compare the numbers of

  users who return to the site after losing a game with the number who return after winning. This knowledge can help you improve both your user experience and your business strategy.

  Box 4: User flows

  The User Flows tool visualizes how users navigate between the pages and features of your site. It's great for answering questions like:

  1.

  How do users navigate away from a page on your site?

  2.

  What do users click on a page on your site?

  3.

  Where are the places that users churn most from your site?

  4.

  Are there places where users repeat the same action over and over?

  Incorrect Answers:

  Funnel: If your application involves multiple stages, you need to know if most customers are progressing through the entire process, or if they are ending the process at some point. The progression through a series of steps in a web

  application is known as a funnel. You can use Azure Application Insights Funnels to gain insights into your users, and monitor step-by-step conversion rates.

• Question 207:

  DRAG DROP

  You are developing an application to securely transfer data between on-premises file systems and Azure Blob storage. The application stores keys, secrets, and certificates in Azure Key Vault. The application uses the Azure Key Vault APIs.

  The application must allow recovery of an accidental deletion of the key vault or key vault objects. Key vault objects must be retained for 90 days after deletion.

  You need to protect the key vault and key vault objects.

  Which Azure Key Vault feature should you use? To answer, drag the appropriate features to the correct actions. Each feature 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:

  

  Correct Answer:

  

  Box 1: Soft delete

  When soft-delete is enabled, resources marked as deleted resources are retained for a specified period (90 days by default). The service further provides a mechanism for recovering the deleted object, essentially undoing the deletion.

  Box 2: Purge protection

  Purge protection is an optional Key Vault behavior and is not enabled by default. Purge protection can only be enabled once soft-delete is enabled.

  When purge protection is on, a vault or an object in the deleted state cannot be purged until the retention period has passed. Soft-deleted vaults and objects can still be recovered, ensuring that the retention policy will be followed.

  Select and Place:

  

  Correct Answer:

  

  Metadata.Add example: // Add metadata to the dictionary by calling the Add method metadata.Add("docType", "textDocuments");

  SetMetadataAsync example: // Set the blob's metadata. await blob.SetMetadataAsync(metadata);

  // Set the blob's properties. await blob.SetPropertiesAsync();

• Question 209:

  DRAG DROP

  You are developing a solution for a hospital to support the following use cases:

  1.

  The most recent patient status details must be retrieved even if multiple users in different locations have updated the patient record.

  2.

  Patient health monitoring data retrieved must be the current version or the prior version.

  3.

  After a patient is discharged and all charges have been assessed, the patient billing record contains the final charges.

  You provision a Cosmos DB NoSQL database and set the default consistency level for the database account to Strong. You set the value for Indexing Mode to Consistent.

  You need to minimize latency and any impact to the availability of the solution. You must override the default consistency level at the query level to meet the required consistency guarantees for the scenarios.

  Which consistency levels should you implement? To answer, drag the appropriate consistency levels to the correct requirements. Each consistency level 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:

  

  Correct Answer:

  

  Box 1: Strong

  Strong: Strong consistency offers a linearizability guarantee. The reads are guaranteed to return the most recent committed version of an item. A client never sees an uncommitted or partial write. Users are always guaranteed to read the

  latest committed write.

  Box 2: Bounded staleness

  Bounded staleness: The reads are guaranteed to honor the consistent-prefix guarantee. The reads might lag behind writes by at most "K" versions (that is "updates") of an item or by "t" time interval. When you choose bounded staleness, the

  "staleness" can be configured in two ways:

  The number of versions (K) of the item

  The time interval (t) by which the reads might lag behind the writes

  Box 3: Eventual

  Eventual: There's no ordering guarantee for reads. In the absence of any further writes, the replicas eventually converge.

  Incorrect Answers:

  Consistent prefix: Updates that are returned contain some prefix of all the updates, with no gaps. Consistent prefix guarantees that reads never see out-of-order writes.
