1. MongoDB is a__ type of database.

Explanation

MongoDB is classified as a NoSQL database because it does not use the traditional SQL language for querying and manipulating data. Instead, it uses a flexible, document-oriented approach where data is stored in JSON-like documents. NoSQL databases are known for their ability to handle large amounts of unstructured or semi-structured data, making them suitable for modern applications that require scalability and flexibility.

2. How many fields in a BSON can be indexed in MongoDB? 

Explanation

All fields in a BSON can be indexed in MongoDB. This means that any field within a BSON document can be indexed to improve query performance. By indexing all fields, MongoDB allows for efficient searching and sorting operations on any field in the document. This flexibility in indexing is a key feature of MongoDB that enables developers to optimize their database queries based on their specific application requirements.

Submit
3. What type of document storage does MongoDB make use of? 

Explanation

MongoDB makes use of BSON (Binary JSON) as its document storage format. BSON is a binary representation of JSON-like documents, providing a more efficient and compact way to store and retrieve data. It includes additional data types compared to JSON, such as Date and Binary, and supports indexing and querying for efficient data retrieval. BSON is used by MongoDB to store and manipulate data, making it a suitable choice for handling large amounts of structured and unstructured data.

4. Which of these is not a feature of MongoDB? 

Explanation

Extraction is not a feature of MongoDB. MongoDB is a NoSQL database that offers features like indexing, replication, and aggregation. Indexing allows for efficient querying and searching of data, replication ensures data redundancy and high availability, and aggregation allows for complex data analysis and processing. However, extraction, which typically refers to the process of retrieving specific data from a database, is not mentioned as a feature of MongoDB.

Submit
5. What language is used in writing MongoDB?

Explanation

MongoDB is written primarily in C++ and C, which are low-level programming languages known for their efficiency and performance.
