Demo Questions

Question 1
You have an Azure Cosmos DB for NoSQL container. The container contains items that have the following properties.
You need to protect the data stored in the container by using Always Encrypted. For each property, you must use the strongest type of encryption and ensure that queries execute properly.
What is the strongest type of encryption that you can apply to each property? To answer, select the appropriate options in the answer area.
Correct answer: To work with this question, an Exam Simulator is required.
Question 2
You have an Azure Cosmos DB account named account1.
You have several apps that connect to account1 by using the account's secondary key.
You then configure the apps to authenticate by using service principals.
You need to ensure that account1 will only allow apps to connect by using an Azure AD identity.
Which account property should you modify?
  1. disableKeyBasedMetadataWriteAccess
  2. disableLocalAuth
  3. userAssignedIdentities
  4. allowedOrigins
Correct answer: B
Question 3
You plan to create an operational system that will store data in an Azure Cosmos DB Core (SQL) API account.
You need to configure the account to meet the following requirements:
  • Support Spark queries.
  • Support the analysis of data from the last six months.
  • Only pay for analytical compute when running queries.
Which three actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
  1. Enable Azure Synapse Link for the account.
  2. Create a container and set the analyticalTTL property to six months.
  3. Create an Azure Databricks notebook.
  4. Create an Azure Synapse linked service.
  5. Create a container and set the time to live to six months.
  6. Create an Azure Synapse pipeline.
Correct answer: A, B, C
Question 4
You develop an application that uses Azure Cosmos DB Core (SQL) API.
You create an Azure pipeline to build and deploy the application.
You need to change the pipeline to run integration tests that you wrote for the application. The solution must execute entirely in the pipeline.
What should you add to the pipeline?
  1. a deployment group named Cosmos DB testing
  2. an Azure Cosmos DB Emulator task
  3. a NuGet service connection that uses an Azure Cosmos DB API key
  4. a secret variable that has a connection string to an Azure Cosmos DB database
Correct answer: D
Question 5
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.
