Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Elimination of configuration drift
Immutable infrastructure means servers are never modified after deployment; instead, they are replaced with new instances. This eliminates configuration drift and ensures consistency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduced need for configuration management
Why it's wrong here
Configuration management is still needed to build the immutable images.
- ✗
Easier manual patching of running servers
Why it's wrong here
Immutable infrastructure discourages manual changes; servers are replaced.
- ✓
Elimination of configuration drift
Why this is correct
Since servers are replaced rather than modified, drift is eliminated.
- ✗
Lower cost due to reusable hardware
Why it's wrong here
Costs may vary, but the primary benefit is consistency, not necessarily lower cost.
