핫스팟 질문
Azure Cosmos DB for NoSQL 계정에 연결하는 애플리케이션을 개발하고 있습니다.
해당 계정에는 읽기/쓰기 영역 하나와 추가 읽기 영역 하나가 있습니다. 이러한 영역들은 자동 장애 조치(failover)를 위해 구성되어 있습니다.
해당 계정에는 다음과 같은 연결 문자열이 있습니다. (줄 번호는 참조용으로만 포함되어 있습니다.)
다음 각 문장에 대해, 문장이 사실이면 '예'를 선택하고, 그렇지 않으면 '아니요'를 선택하십시오.
참고: 정답 하나당 1점입니다.
Correct Answer:

Explanation:
Box 1: No
The same connection string can still be used.
Azure Cosmos DB Core read write region connection strings
Azure Cosmos DB "primary write region" failover "connection string"
Box 2: No
The AccountEndpoint for both are the same.
Box 3: Yes
The ConnectionPolicy.PreferredLocations property gets and sets the preferred locations (regions) for geo-replicated database accounts in the Azure Cosmos DB service. For example, "East US" as the preferred location.
When EnableEndpointDiscovery is true and the value of this property is non-empty, the SDK uses the locations in the collection in the order they are specified to perform operations, otherwise if the value of this property is not specified, the SDK uses the write region as the preferred location for all operations.

핫스팟 질문
여러 지역에 걸쳐 있는 Azure Cosmos DB 계정(account1)이 있으며 기본 일관성 수준이 강력(strong)으로 설정되어 있습니다.
App1이라는 앱이 있는데, 이 앱은 세션 일관성 수준을 요청하도록 구성되어 있습니다.
App1의 읽기 및 쓰기 작업은 어떻게 처리될까요? 답변하려면 답변 영역에서 적절한 옵션을 선택하세요.
Correct Answer:

Explanation:
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.
