1Z0-1085-26 Getting Started With Oci Practice Question
A DevOps engineer is provisioning compute instances in a region that has a single availability domain. To protect the application from unexpected physical hardware failures and power supply outages within that single availability domain, how should the engineer distribute the instances?
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
✓
Across different Fault Domains
Fault domains provide anti-affinity and isolate instances across different physical hardware, power, and network infrastructure within a single availability domain.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Across multiple OCI Regions
Why it's wrong here
The region only has a single availability domain and deploying across multiple regions is overkill for simple intra-datacenter rack failure protection.
- ✗
Inside the same Fault Domain
Why it's wrong here
Placing all instances in the same fault domain would mean they share the exact same physical hardware and risk simultaneous failure.
- ✓
Across different Fault Domains
Why this is correct
Fault domains allow you to distribute your instances so that they do not share the same physical hardware and power infrastructure within an availability domain.
- ✗
Across multiple Availability Domains
Why it's wrong here
The scenario specifies that the region has only a single availability domain.
