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
✓
They provide anti-affinity by ensuring instances placed in different fault domains do not run on the same physical hardware.
Fault domains are logical groupings of hardware within an AD that provide anti-affinity, protecting against unexpected hardware and power failures.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Each availability domain contains exactly one fault domain.
Why it's wrong here
Each commercial availability domain contains multiple fault domains (typically three).
- ✓
They provide anti-affinity by ensuring instances placed in different fault domains do not run on the same physical hardware.
Why this is correct
Fault domains isolate your instances so they do not share physical infrastructure.
- ✗
They span across multiple geographic regions to provide disaster recovery.
Why it's wrong here
Fault domains exist strictly within a single availability domain.
- ✓
They help protect applications against unexpected hardware failures and power supply outages within an availability domain.
Why this is correct
Fault domains provide isolation from physical hardware and top-of-rack switch failures.
- ✗
They are isolated data centers connected by high-speed, low-latency cross-links.
Why it's wrong here
This describes Availability Domains, not Fault Domains.
