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!

Okay, couldn't stop thinking about this question, and I think I found the bloody trick behind this question. Still the proposed answer A. is correct, but for different reasons. Regarding D. Azure Cosmos DB Data Migration Tool: When looking at the GitHub repository it says: "The Azure Cosmos DB Data Migration Tool is an open source solution to import data to Azure CosmosDB ____SQL API_____ (DocumentDB) and Table API endpoints from a variety of sources..." Okay fine. But the reason why this is still the wrong answer is because of the question. "You plan to migrate MongoDB to an Azure Cosmos DB account that uses the ____MongoDB API.____". And thats why A. mongorestore is the only correct answer here.

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 ..

Regarding D). What's strange is that when looking at the tool it seems to support it. Also the github page states it's supported: https://github.com/Azure/azure-documentdb-datamigrationtool. Could be this question is outdated.

A. mongorestore https://azure.microsoft.com/en-us/resources/videos/using-mongodb-tools-with-azure-cosmos-db/ B. Data Migration Assistant > Doesn't support MongoDB, can be ruled out! C. Azure Storage Explorer > Doesn't make sense at all, can be ruled out! D. Azure Cosmos DB Data Migration Tool > Quote "The 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 Conclusion: Answer A) is correct!

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
