AZ-204 Certification Practice Question #9

Question

This question requires that you evaluate the underlined text to determine if it is correct.
You company has an on-premises deployment of MongoDB, and an Azure Cosmos DB account that makes use of the MongoDB API.
You need to devise a strategy to migrate MongoDB to the Azure Cosmos DB account.
You include the Data Management Gateway tool in your migration strategy.
Instructions: Review the underlined text. If it makes the statement correct, select `No change required.` If the statement is incorrect, select the answer choice that makes the statement correct.

Accepted Answer

To migrate data offline from an on-premises MongoDB database to Azure Cosmos DB's API for MongoDB, you can use MongoDB native tools. For migrating an entire database, `mongodump` and `mongorestore` are the recommended tools because they use the compact binary JSON (BSON) format, which is more efficient for network transfers. The `mongorestore` utility connects to the target Cosmos DB instance using the connection string and imports the BSON dump files. The other options are incorrect: Data Management Gateway and AzCopy are not designed for MongoDB migrations, and Azure Storage Explorer is used for managing Azure Storage resources.
