hard📝 Trade-off Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Understand challenges of scaling with Mutual TLS
Dynamic scaling requires automated certificate management to avoid manual errors and delays.Step 2: Evaluate options for secure and scalable management
A centralized CA with automation allows issuing and rotating certificates securely as instances scale.Step 3: Reject insecure or manual approaches
Manual distribution is error-prone, disabling TLS reduces security, and sharing certificates risks compromise.Final Answer:
Use a centralized certificate authority with automated certificate issuance and rotation -> Option AQuick Check:
Central CA + automation = scalable Mutual TLS [OK]
Quick Trick: Automate certs with central CA for scaling [OK]
Common Mistakes:
MISTAKES- Manually managing certs for each instance
- Disabling Mutual TLS to avoid complexity
- Sharing certificates across instances
