Exam AZ-301 topic 5 question 2 discussion

I would select D - Azure Cosmos DB Data Migration Tool https://azure.microsoft.com/en-us/updates/documentdb-data-migration-tool/

A: mongorestore is supported for a Azure Cosmos DB, alternately, Azure Data Migration Service. Given the later is not an answer, then, the only answer is: A, since this is a "one time" migration. https://azure.microsoft.com/en-us/resources/videos/using-mongodb-tools-with-azure-cosmos-db/ https://www.youtube.com/watch?v=YWnvcKcs7Qk

This one comes by elimination. It's A because the other options don't make a lot of sense. DMA is for SQL servers (https://docs.microsoft.com/en-us/sql/dma/dma-overview?view=sql-server-ver15). The azure storage explorer it does not make any sense. The cosmos DB migration, does NOT support MongoDB API (directly). So the only remaining option is the A even if I think it looks strange these days.

given answer is correct as Azure Database Migration Service and Azure Database Migration tool both are different ,tool only support SQL API and Table API , it does not support Azure Cosmos DB's API for MongoDB ,Cassandra API and Gremlin API https://docs.microsoft.com/en-us/azure/cosmos-db/import-data we have following migration option to migrate MongoDB to an Azure Cosmos DB account that uses the MongoDB API :- Online Azure Database Migration Service Offline Azure Database Migration Service Offline Azure Data Factory Offline Existing Mongo Tools (mongodump, mongorestore, Studio3T) https://docs.microsoft.com/en-us/azure/cosmos-db/cosmosdb-migrationchoices

A. mongorestore

A is correct answer

A ie Mangorestore seems correct. Azure Cosmos DB Data Migration tool doesn't currently support Azure Cosmos DB's API for MongoDB either as a source or as a target. https://docs.microsoft.com/en-us/azure/cosmos-db/import-data

Based on all previous answers: A is correct.

https://azure.microsoft.com/en-us/updates/documentdb-data-migration-tool/ D is correct answer based on 1st paragraph here. Also, DataBASE Migration Assistant would be correct but that is not an option here

https://azure.microsoft.com/en-us/updates/documentdb-data-migration-tool/ D!

You can use Either Mangorestore or DMS . https://www.youtube.com/watch?v=YWnvcKcs7Qk

i think, the answer should be D based on Microsoft documentation https://docs.microsoft.com/en-us/azure/cosmos-db/cosmosdb-migrationchoices( Section Mongo DB API ) Not sure what I am missing here ..

Answer is D This tutorial provides instructions on using the Azure Cosmos DB Data Migration tool, which can import data from various sources into Azure Cosmos containers and tables. You can import from JSON files, CSV files, SQL, MongoDB, Azure Table storage, Amazon DynamoDB, and even Azure Cosmos DB SQL API collections. You migrate that data to collections and tables for use with Azure Cosmos DB. The Data Migration tool can also be used when migrating from a single partition collection to a multi-partition collection for the SQL API.

with the available choices, answer A should be the correct answer unless there is Azure DMS as an option

I guess the question is outdated. There should be another option E) which is called "Azure Database Migration Service". That would be the right answer according to this link: https://docs.microsoft.com/en-us/azure/dms/tutorial-mongodb-cosmos-db?toc=/azure/cosmos-db/toc.json&bc=/azure/cosmos-db/breadcrumb/toc.json

Correct Answer: B Azure Database Migration Service to perform an online (minimal downtime) migration of databases from an on-premises or cloud instance of MongoDB to Azure Cosmos DB's API for MongoDB. https://docs.microsoft.com/en-us/azure/dms/tutorial-mongodb-cosmos-db-online

The answer is D https://azure.microsoft.com/en-us/updates/documentdb-data-migration-tool/ With the Azure Cosmos DB Data Migration tool, you can easily migrate data to Azure Cosmos DB. The Azure Cosmos DB Data Migration tool is an open source solution that imports data to Azure Cosmos DB from a variety of sources, including: -JSON files -MongoDB -SQL Server -CSV files -Azure Cosmos DB collections
