You want to secure a microservices system so only authorized users can access specific services. Which combination is best?
AUse API Gateway with token-based authentication and encryption
BUse load balancer with caching and logging
CUse database indexing and open access
DUse firewall only without authentication
Step-by-Step Solution
Solution:

  1. Step 1: Identify security needs for authorization and protection

    Authorization requires verifying users and protecting data in transit.

  2. Step 2: Match tools to needs

    API Gateway controls access, tokens verify identity, and encryption protects data.

  3. Step 3: Eliminate unsuitable options

    Load balancers, caching, logging, indexing, open access, or firewall alone do not provide full security.

  4. Final Answer:

    Use API Gateway with token-based authentication and encryption -> Option A

  5. Quick Check:

    API Gateway + tokens + encryption = Secure access [OK]
Quick Trick: Combine gateway, tokens, and encryption for best security [OK]
Common Mistakes:
MISTAKES
  • Relying only on firewall without authentication
  • Confusing load balancer with security tool
  • Allowing open access thinking it's safe
