You have an Azure Cosmos DB account named Account1. Account1 resides in the East US Azure region and contains a database named DB1. DB1 contains a collection named Coll1. Coll1 has a limit of 25, 000 request units per second (RU/s). The consistency level of Account1 is set to Session.
You need to make Coll1 available for read operations in the West US Azure region. The solution must ensure that the performance of the read operations in West US is the same as the performance of the read operations in East US. The solution must minimize costs.
What should you do?

• A. Create a read-only replica of Account1 in West US. Set the RU/s of DB1 to 50,000
• B. Create a read-only replica of Account1 in West US. Set the RU/s of Coll1 to 50,000
• C. Create a read-only replica of Account1 in West US. Leave the RU/s of Coll1 unchanged.
• D. Set the consistency level to Bounded Staleness. Create a read-only replica of Account1 in West US.

You have a binary dump of a MongoDB database
You need to migrate the database to Azure Cosmos DB
What should you use?

• A. the Cosmos DB Data Migration Tool
• B. mongoimport.exe
• C. mongomirror.exe
• D. mongorestore.exe

You have an Azure Cosmos DB database that uses the Table API. The database contains a table that includes the student data of a school.
A subset of the data is shown in the following table.

Another student named Matt Berg joins the school.
You need to add a new entity for the new student.
Solution: You run the following Azure Power Shell command.
Add-StorageTableRow -table $Table_name -partitionKey 1 -rowkey ("matt_berg_0723") -property @{"First Name"-"Matt"; Last Name"-"Berg"; "Age"-9}
Does this meet the goal?

• A. Yes
• B. No

You have an Azure Cosmos DB account named Account1. Account1 contains a database named DB1. DB1 contains a collection named Coll1 Account has a write region of East US and a read region of West US. Coll1 contains 500,000 documents that are 1 KB each.
You have two applications named App1 and App2 that read documents from Coll1 in the East US region at a steady rate of 1,000 request units per second (RU/s). Both applications consistently throw an exception that has the 429 HTTP status code.
You need to recommend a solution to minimize the number of exceptions. The solution must minimize costs.
What should you recommend?

• A. Set the indexing mode of Coll1 to Lazy
• B. increase the number of request units (RUs) for Coll1.
• C. Modify the connection policy of App2
• D. Set the default consistency level of DB1 to Bounded Staleness
