Rest API - Caching Strategies

Which of the following best explains how caching helps REST APIs handle more users?

ABy encrypting all API responses

BBy storing frequent responses, it reduces repeated database queries

CBy increasing the size of the server's memory

DBy blocking some users from accessing the API

Step-by-Step Solution

Solution:

Step 1: Identify caching effect on database queries
Caching stores frequent responses, so the server avoids querying the database repeatedly.
Step 2: Understand impact on user handling
Less database querying means faster responses and the ability to serve more users efficiently.
Final Answer:
By storing frequent responses, it reduces repeated database queries -> Option B
Quick Check:
