Microsoft Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB Sample Questions (Q112-Q117):

NEW QUESTION # 112
You have a container named container1 in an Azure Cosmos DB for NoSQL account named account1.
You configure container1 to use Always Encrypted by using an encryption policy as shown in the C# and the Java exhibits. (Click the C# tab to view the encryption policy in C#. Click the Java tab to see the encryption policy in Java.)

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Explanation:
According to the Azure Cosmos DB documentation 1 , Always Encrypted is a feature designed to protect sensitive data, such as credit card numbers or national identification numbers, stored in Azure Cosmos DB.
Always Encrypted allows clients to encrypt sensitive data inside client applications and never reveal the encryption keys to the database.
To use Always Encrypted, you need to define an encryption policy for each container that specifies which properties should be encrypted and which data encryption keys (DEK) should be used. The DEKs are stored in Azure Cosmos DB and are wrapped by customer-managed keys (CMK) that are stored in Azure Key Vault.
Based on the encryption policy shown in the exhibits, the creditcard property is encrypted with a DEK named dek1, and the SSN property is encrypted with a DEK named dek2. Both DEKs are wrapped by a CMK named cmk1.
To answer your statements:
* You can perform a query that filters on the creditcard property = No . This is because the creditcard property is encrypted and cannot be used for filtering or sorting operations 1 .
* You can perform a query that filters on the SSN property = No . This is also because the SSN property is encrypted and cannot be used for filtering or sorting operations 1 .
* An application can be allowed to read the creditcard property while being restricted from reading the SSN property = Yes . This is possible by using different CMKs to wrap different DEKs and applying access policies on the CMKs in Azure Key Vault. For example, if you use cmk2 to wrap dek2 instead of cmk1, you can grant an application access to cmk1 but not cmk2, which means it can read the creditcard property but not the SSN property 2 .

NEW QUESTION # 113
Hotspot Question
You plan to create an Azure Cosmos DB database named db1 that will contain two containers.
One of the containers will contain blog posts, and the other will contain users. Each item in the blog post container will include:
- A single blog post
- All the comments associated to the blog post
- The names of the users who created the blog post and added the
comments
You need to design a solution to update usernames in the user container without causing data integrity issues. The solution must minimize administrative and development effort.
What should you include in the solution? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

NEW QUESTION # 114
You maintain a relational database for a book publisher. The database contains the following tables.

The most common query lists the books for a given authorId.
You need to develop a non-relational data model for Azure Cosmos DB Core (SQL) API that will replace the relational database. The solution must minimize latency and read operation costs.
What should you include in the solution?

A. Create a container for Author and a container for Book. In each Author document, embed booked for each book by the author. In each Book document embed author of each author.
B. Create a container that contains a document for each Author and a document for each Book. In each Book document, embed authorId.
C. Create Author, Book, and Bookauthorlnk documents in the same container.
D. Create a container for Author and a container for Book. In each Author document and Book document embed the data from Bookauthorlnk.

Answer: A

Explanation:
Store multiple entity types in the same container.

NEW QUESTION # 115
You have a container named contained in an Azure Cosmos DB for NoSQL account.
The following is a sample of a document in container1.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Explanation:

NEW QUESTION # 116
Hotspot Question
You have an Azure Cosmos DB for NoSQL account.
You plan to create a container named container1. The container1 container will store items that include two properties named name and age.
The most commonly executed queries will query container1 for a specific name. The following is a sample of the query.

You need to define an opt-in indexing policy for container1. The solution must meet the following requirements:
- Minimize the number of request units consumed by the queries.
- Ensure that the _etag property is excluded from indexing.
How should you define the indexing policy? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
