NEW QUESTION # 82
You have an Azure Cosmos DB for NoSQL account named account1 that has a single read-write region and one additional read region. Account1 uses the strong default consistency level.
You have an application that uses the eventual consistency level when submitting requests to account1.
How will writes from the application be handled?
Answer: B
Explanation:
Overriding the default consistency level only applies to reads within the SDK client. An account configured for strong consistency by default will still write and replicate data synchronously to every region in the account. When the SDK client instance or request overrides this with Session or weaker consistency, reads will be performed using a single replica.

NEW QUESTION # 84
Note: This section contains one or more sets of questions with the same scenario and problem. Each question presents a unique solution to the problem. You must determine whether the solution meets the stated goals. More than one solution in the set might solve the problem. It is also possible that none of the solutions in the set solve the problem.
After you answer a question in this section, you will NOT be able to return. As a result, these questions do not appear on the Review Screen.
You have an Azure Cosmos DB for NoSQL database. The database hosts a container named families that stores data in the following format.
You need to return the following data:
- The ID of the family
- The family names of the children
- The name of any pets if the pet is a cat
Solution: You run the following query.
Does this meet the goal?
Answer: A
Explanation:
Correct:
* You run the following query.
The following Azure Cosmos DB NoSQL query fulfills the requirements by unnesting child array items and filtering the pet array:
To retrieve the family ID, the children's family names, and the rabbit's name, you can use the query below.
SELECT f.id, c.familyName AS FamilyName, p.givenName AS petName
FROM families f
JOIN f.children c
JOIN (SELECT VALUE p FROM p IN c.pets WHERE p.type = 'cat') AS p
1. Flatten the Children Array
To access individual properties within the children sub-array, use a JOIN statement. In Azure Cosmos DB, a JOIN performs an inner product between the document root (f) and the array (f.children). This filters out any family documents that contain no children.
2. Isolate Cat Pets
To inspect the properties of the pets array embedded inside each child, apply a secondary JOIN on c.pets. The WHERE clause then filters these projected items to only include cases where the property $p.type$ matches the string "cat".
3. Project Specific Attributes
The SELECT clause restricts the final JSON output schema to contain exactly three custom- aliased properties:
familyId: Extracted from the root document
IDchildFamilyName: Extracted from the current child item
iterationpetName: Extracted from the matching pet item iteration
Incorrect:
* You run the following query.
Use two JOINS and one subquery, not three JOINS and a subquery.
* You run the following query.
CROSS APPLY should not be used.
