최신 Azure Cosmos DB Developer Specialty DP-420 무료샘플문제 (Q15-Q20):

질문 # 15
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?

A. Writes will use the eventual consistency level.
B. Writes will use the strong consistency level.
C. Azure Cosmos DB will reject writes from the application.
D. The write order is not guaranteed during replication.

정답：B

설명：
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.
Reference:
https://docs.microsoft.com/en-us/azure/cosmos-db/consistency-levels

질문 # 16
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?

A. disableKeyBasedMetadataWriteAccess ,
B. userAssignedldentatxe
C. allowedOrxgins
D. disableLocalAuth

정답：D

설명：
The disableLocalAuth property is a boolean flag that indicates whether local authentication methods such as primary/secondary keys are disabled for the Azure Cosmos DB account. Setting this property to true improves security by ensuring that Azure Cosmos DB accounts exclusively require Azure Active Directory identities for authentication1.

질문 # 17
You have an Azure Cosmos DB Core (SQL) API account named account1.
In account1, you run the following query in a container that contains 100GB of data.
SELECT *
FROM c
WHERE LOWER(c.categoryid) = "hockey"
You view the following metrics while performing the query.

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

정답：

설명：

Explanation:

Box 1: No
Each physical partition should have its own index, but since no index is used, the query is not cross-partition.
Box 2: No
Index utilization is 0% and Index Look up time is also zero.
Box 3: Yes
A partition key index will be created, and the query will perform across the partitions.
Reference: https://docs.microsoft.com/en-us/azure/cosmos-db/sql/how-to-query-container

질문 # 18
You have a database in an Azure Cosmos DB for NoSQL account that is configured for multi-region writes.
You need to use the Azure Cosmos DB SDK to implement the conflict resolution policy for a container. The solution must ensure that any conflict sent to the conflict feed.
Solution: You set ConfilictResolutionMode to Custom. You Set ResolutionProcedures to a custom stored procedure. You configure the custom stored procedure to use the conflictingItems parameter to resolve conflict.
Does this meet the goal?

A. Yes
B. No

정답：B

설명：
Setting ConflictResolutionMode to Custom and configuring a custom stored procedure with the "conflictingItems" parameter will allow you to implement a custom conflict resolution policy. This will ensure that any conflicts are sent to the conflict feed for resolution.

질문 # 19
You have an Azure Cosmos DB for NoSQL container named Container1.
You run SQL queries against Container1 by using the Azure Cosmos DB .NET SDK.
You need to identify the number of request units consumed by each query.
Which two items can you use? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

A. IDocumentQuery
B. ResourceResponse
C. StoredProcedureResponse
D. RequestOptions

정답：A,B

설명：
To identify the number of request units (RUs) consumed by each query using the Azure Cosmos DB .NET SDK (specifically v2 API / DocumentClient syntax implied by your choices), you should use IDocumentQuery and FeedResponse.
ResourceResponse: In the legacy Azure Cosmos DB .NET SDK (v2), query and item operations return a ResourceResponse<T> object. This object contains a RequestCharge property that explicitly yields the number of RUs consumed by the database operation.
IDocumentQuery: When you perform asynchronous pagination or streaming of SQL query results in the v2 .NET SDK, the IDocumentQuery<T> interface is implemented. This interface exposes properties and response fields that catch execution metrics-including total request charges-as you iterate through your data feed.
