You are the data engineer for your company. An application uses a NoSQL database to store data. The database uses the key-value and wide-column NoSQL database type.
Developers need to access data in the database using an API.
You need to determine which API to use for the database model and type.
Which two APIs should you use? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
To access data in a NoSQL database that uses both key-value and wide-column types, the appropriate APIs to use would be the Table API and the Cassandra API. The Table API is well-suited for key-value storage, providing efficient access and manipulation of key-value pairs. On the other hand, the Cassandra API is designed for wide-column storage, which is optimized for handling large datasets where data is stored in columns instead of rows.
it should ba A and E
as per documentation mongo API is multi-model and supports document, key-value, graph, and columnar data models so answer is correct ref https://docs.microsoft.com/en-us/azure/cosmos-db/mongodb-introduction
No, the documentation didn't refer to that
Answer is clearly A and E. No documentation refers to Mongo API .
No, the documentation didn't refer to that
Answer is clearly A and E. No documentation refers to Mongo API .
key value --> Table API graph --> Gremlin API document --> SQL API and MongoDB API columnar --> Cassandra API so, the answer is A,E
right answer is A,E but slight change in your description. key value --> Cassandra API graph --> Gremlin API document --> SQL API and MongoDB API columnar --> Table API https://cloud.netapp.com/blog/azure-cvo-blg-azure-nosql-types-services-and-a-quick-tutorial#H_H1
As far as I understand, the Key Value interface should be Azure table, unless there is a legacy requirement for something else.
B & E is correct as the application uses NoSQL database. We can't choose the table API as the requirement not stated that the application uses blob storage (blob storage is not a database).
A and E, check the answer to question 17 later
It’s D & E. Microsoft advises that Table API should only be used when migrating from Tables to CosmosDB. For any new deployment, use SQL API - this is the same when selecting MongoDB API. You would only select MongoDB API if a legacy system needs to interface to the CosmosDB database.
Actually, after re-reading the question... it is B & E
What is the requirement to use MongoDB here? It is not neither key-value nor wide column.
What is the requirement to use MongoDB here? It is not neither key-value nor wide column.
D & E , sql api is key value, for any new deployment, use SQL API , wide column is cassandra
Does the data consist of simple key-value pairs? Before Azure Cosmos DB existed, Redis or the Table API might have been a good fit for this kind of data; however, Core (SQL) API is now the better choice, as it offers a richer query experience, with improved indexing over the Table API. https://docs.microsoft.com/en-us/learn/modules/choose-api-for-cosmos-db/3-analyze-the-decision-criteria

A & E as per https://academy.datastax.com/planet-cassandra/what-is-nosql
really bad and vague question. But i would vote for Table API as it typically supports key Value store. I know others would argue that the Table API should only be used when the data is stored in Azure Table Storage, but this condition is unclear in the question. MangoDB is not a typical key-value store, it should only be consider if the question mentioned that it is a legacy system built in MangoDB. Very badly worded question for sure.
seems lot of debate on this question.. Answer is A & E ( Table & Cassandra).. The same is endorsed in Other Website.. Why not Mongo - It's doument but not Key-value pair storage or not wide-column.
It should be D and E. Before Azure Cosmos DB existed, Redis or the Table API might have been a good fit for this kind of data; however, Core (SQL) API is now the better choice, as it offers a richer query experience, with improved indexing over the Table API.
Think the question is unclear - is this a legacy question or not? If it isn't legacy then there is 1 answer - D as guidance is to use Core SQL even for wide-column. Because it requires 2 answers then it must be legacy so B and E.
A and E https://docs.microsoft.com/en-us/learn/modules/choose-api-for-cosmos-db/2-identify-the-technology-options
Key-Value -> Table API, Wide-Column -> Cassandra API
key Value is Table where as Wide column is Casandra
A&E Table API is key value Cassandra is wide column
It should be A & E
The answer should be Table API for key value and Cassandra API for wide column
Answer is Table APi and cassandra API
Should B not be Azure Cosmos DB?
No, it is asking for an API. Cosmos is not an API... If a NoSQL solution uses Mongo or Cassandra the idea is that it's easy to migrate it onto Cosmos later.
With just two options to select Why not A & B ? (option B) As Mongo DB is a cross platform document-oriented DB as Cosmos with json-like documents with schema seems to me more applicable than Cassandra (high-availability)
The correct answer is B and E as seen in other websites
Key value pair - SQL API. "Before Azure Cosmos DB existed, Redis or the Table API might have been a good fit for this kind of data; however, Core (SQL) API is now the better choice, as it offers a richer query experience, with improved indexing over the Table API."
I think it should be MongoDB, since it uses key-value (which is the json format in document). but not storing the key-value pairs(then should be Table API)
https://www.mongodb.com/key-value-database
ignore it. I would go for Table
it should be A and E
It's A & E Cassandra is wide-table and Table is key
Azure CosmosDB table API is a key-value storage hosted in the cloud. It's a part of Azure Cosmos DB, that is Microsoft's multi-model database. It's a globally distributed, low latency, high throughput solution with client SDKs available for . NET, Java, Python, and Node. So Answer will be A and E
Should be A (Table API) and E (Cassandra API). Table API is the best solution for key-value model.
AE. Table uses key/value. Not MongoDB. B is wrong.
It's A (Table API for key-value pairs) and E (Cassandra API for wide-columns)
Table API and Cassandra API for sure
A & E certainly
Key-Value -> Table API Wide column -> Cassandra API
It's A and E.
the correct answer is Table Api e Cassandra Api. so A - E
