hard📝 Conceptual Q10 of 15
Step-by-Step Solution
Solution:
Step 1: Understand immutability purpose
Immutable versions prevent changes that could break functions unexpectedly.Step 2: Identify reason for explicit versioning
Explicit version references ensure functions use tested, stable code.Final Answer:
To ensure function stability by avoiding unexpected code changes -> Option BQuick Check:
Immutable layers = stable, predictable function behavior [OK]
Quick Trick: Immutable layers keep functions stable and predictable [OK]
Common Mistakes:
- Thinking immutability reduces costs
- Assuming layers auto-update functions
- Believing layers run in separate containers
