ABecause service instances can change IPs and locations frequently
BBecause it stores all user data centrally
CBecause it replaces the need for API Gateways
DBecause it manages database schema migrations
Step-by-Step Solution
Solution:
  1. Step 1: Understand dynamic environments

    Microservices often scale up/down or move, changing IPs and locations.
  2. Step 2: Role of service discovery

  3. Step 3: Exclude unrelated roles

    It does not store user data, replace API Gateways, or manage database schemas.
  4. Final Answer:

    Because service instances can change IPs and locations frequently -> Option A
  5. Quick Check:

    Service discovery = track changing service locations [OK]
Quick Trick: Service discovery tracks where services live dynamically [OK]
