NEW QUESTION # 43
You have an Azure Cosmos DB for NoSQL account that contains a container named container1.
You plan to use container1 as a key-value store that will perform point reads on the item ID and partition key.
You need to define an indexing policy for container! The solution must meet the following requirements:
* Provide the ability to set DefauitTimeToLive for container1.
* Minimize implementation time.
* Minimize costs.
How should you complete the JSON definition of the indexing policy? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

NEW QUESTION # 44
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 documentation1, 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 operations1.
* 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 operations1.
* 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 property2.
NEW QUESTION # 45
Hotspot Question
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.

NEW QUESTION # 46
You have an Azure Cosmos DB for NoSQL account that contains a database named DB1.
Users run the following query against DB1.
SELECT *
FROM c
WHERE c.bikeParts = "Frame, Chain, Peddles"
ORDER BY c.bikeParts ASC
You add an index to the recordset.
You need to change the ORDER BY syntax of the query to optimize the use of the index. The solution must NOT change the result set.
Which syntax should you use?
Answer: A
Explanation:
Need to first sort on c.bikeParts DESC to keep the same order.
Note: ts. A read-only and system-generated timestamp. The value is the Document's last-updated timestamp, in seconds from the UNIX epoch.
Incorrect:
[Not A, Not C]
Need ASC c.bikeParts sorting on not DESC
[Not B]
Need to first sort on c.bikeParts to keep the same order.
If the indexing mode is set to consistent, the system properties id and _ts are automatically indexed.
