What is the primary purpose of a Correlation ID in microservices?
ATo balance load between servers
BTo encrypt data between services
CTo track a single request across multiple services for easier debugging
DTo store user session information
Step-by-Step Solution
Solution:

  1. Step 1: Understand the role of Correlation ID

    A Correlation ID is a unique identifier attached to a request that travels through multiple services.

  2. Step 2: Identify its main use

    This ID helps developers trace and debug the flow of that request across distributed systems.

  3. Final Answer:

    To track a single request across multiple services for easier debugging -> Option C

  4. Quick Check:

    Correlation ID = request tracking [OK]
Quick Trick: Correlation ID links logs of one request across services [OK]
Common Mistakes:
MISTAKES
