NoSQL Concepts Quiz

Which of the following database generations is characterized by the rise of relational databases?

• First generation

• Second generation

• Third generation

• Fourth generation

ACID properties are primarily associated with which type of database transactions?

• NoSQL databases

• Graph databases

• Relational databases

• Document databases

Which of the following is NOT one of the ACID properties?

• Atomicity

• Consistency

• Availability

• Durability

BASE properties are often preferred over ACID properties in scenarios prioritizing:

• Strict consistency

• Strong integrity

• High availability and eventual consistency

• Complex joins

What is the primary purpose of database sharding?

• To improve data integrity

• To achieve horizontal scalability

• To enforce ACID properties

• To reduce data redundancy

Brewer's CAP theorem states that a distributed system cannot simultaneously guarantee which three properties?

• Consistency, Atomicity, Partition Tolerance

• Consistency, Availability, Partition Tolerance

• Consistency, Atomicity, Durability

• Consistency, Availability, Durability

In the context of the CAP theorem, if a system prioritizes Consistency and Availability, what must it sacrifice during a network partition?

• Atomicity

• Durability

• Partition Tolerance

• Nothing

Which of the following is a key characteristic of 'Big Data'?

• Primarily small, structured datasets

• Low velocity, low volume, low variety

• High volume, velocity, variety

• Static data only

Which layer of the Big Data stack is NoSQL primarily associated with?

• Data Ingestion

• Data Storage and Processing

• Data Analysis and Visualization

• Application Layer

The shift from vertical scaling to horizontal scaling in databases is often driven by the need to handle:

• Smaller datasets

• Reduced query complexity

• Massive data growth and high traffic

• Stronger ACID guarantees
