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
✓
Deploying applications across multiple Availability Domains to survive a complete facility outage.
Fault domains and availability domains are core mechanisms for infrastructure fault isolation in OCI.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Deploying applications across multiple Availability Domains to survive a complete facility outage.
Why this is correct
Multiple availability domains protect against availability-domain-wide outages.
- ✗
Relying on a single Virtual Cloud Network (VCN) with no backup subnets.
Why it's wrong here
A single VCN without redundancy does not protect against infrastructure faults.
- ✗
Placing all compute instances on a single physical host to maximize internal CPU cache efficiency.
Why it's wrong here
Putting everything on a single host creates a single point of failure.
- ✗
Disabling automated backups to prevent storage controller contention.
Why it's wrong here
Disabling backups reduces data protection and does not improve fault isolation.
- ✓
Distributing instances across multiple Fault Domains to protect against rack-level hardware and power failures.
Why this is correct
Fault domains isolate workloads against local hardware and power issues.
