API: MongoDB API -
Azure Cosmos DB comes with multiple APIs:

✑ MongoDB API, compatible with existing Mongo DB libraries, drivers, tools and applications.
✑ Cassandra API, compatible with existing Apache Cassandra libraries, drivers, tools, and applications.
✑ Azure Table API, a key-value database service compatible with existing Azure Table Storage.
✑ Gremlin (graph) API, a graph database service supporting Apache Tinkerpop's graph traversal language, Gremlin.

the correct answer should be : Account and MongoDB API https://docs.microsoft.com/en-us/azure/cosmos-db/create-mongodb-dotnet

The API determines the type of account to create. Azure Cosmos DB provides five APIs: Core (SQL) for document databases, Gremlin for graph databases, Azure Cosmos DB for Mongo DB API for document databases, Azure Table, and Cassandra. Currently, you must create a separate account for each API.

I think the given answer is correct. The link you supply also explains API determines what account to create, with different API type for different DB, such as Mongo DB API for Cosmos DB, which is the answer for the second question.

In the Azure Cosmos DB account, you would need to create a database. When using the Mongo DB API for Cosmos DB, you have to create a database to store the data.

Azure Cosmos DB provides native support for wire protocol-compatible APIs for popular databases, including MongoDB. The important point here is to understand "wire protocol". By reading this link: https://docs.mongodb.com/manual/reference/mongodb-wire-protocol/ Looks like it's all about API style communication between client to database server. So I would choose "API" for Box 1.

When you create a Cosmos DB account you need to specify: - API: in this case MongoDB API - Version (field only available when you choose Mongo DB API in field API) So answer should be: Account MongoDB API

For "mongodb compatibility" my understanding is: do we have "full" compatibility between mongoDB and CosmosDB (database: can you use mongodb data files directly to CosmosDB) or at other levels ( accounts, ...). And it is clearly explained in Microsoft doc that the compatibility is at the API level So the answer is: API

Ambiguous question. However, the key word is compatibility, which I discovered here: https://docs.microsoft.com/en-us/azure/cosmos-db/mongodb-introduction quote: "By default, new ***accounts*** created using Azure Cosmos DB's API for MongoDB are ***compatible*** with version 3.6 of the MongoDB wire protocol. Any MongoDB client driver that understands this protocol version should be able to natively connect to Cosmos DB." Only direct link to the question I could find.

Check Comment from "AmineHZ" 3 months ago and from "nettekguys" response comments. At least based on the upvotes, you should consider to read the reference and might think abount Option "account" for Box 1.

In addition to my previous post see also the creation script at: https://docs.microsoft.com/en-us/azure/cosmos-db/scripts/cli/mongodb/create and the Screenshot of Setup wizard at Chapter: "Create a migration project", no 4, Screenshot Info hint: To successfully migrat from MongoDB, please: Create a Cosmos DB account with support of MondoDB API.

MongoDB Compatibility: Collection This seems correct to me be because: https://docs.microsoft.com/en-us/azure/container-instances/container-instances-overview Under step 4 -> API, it says: "Select Azure Cosmos DB for Mongo DB API because in this quickstart you are creating a *collection* that works with MongoDB."

this is a bit strange.. i mean it's pretty clear that you should select MongoDb Api as the CosmosDb Api to use... however, the actual 'MongoDb Compatibility' is pretty unclear what they are actually after. When you provision a CosmosDb instance, and choose the MongoDb Api, you actually need to select a version of MongoDb.. i am thinking that perhaps this is the MongoDb Compatibility they are looking for?? Therefore "API".
