1Z0-1085-26 Getting Started With Oci Practice Question
When evaluating OCI regions for deploying a new application, you notice that some regions are designated as having multiple availability domains while others have only one. What is a key design implication when deploying to a single-AD region?
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
✓
You must rely on fault domains for hardware isolation and another region for disaster recovery.
Single-AD regions lack multiple physical data center facilities, so high availability must rely on fault domains for hardware isolation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Compute instances are automatically spread across other global regions.
Why it's wrong here
Instances remain in the deployed region.
- ✓
You must rely on fault domains for hardware isolation and another region for disaster recovery.
Why this is correct
Single-AD regions provide fault domains for rack-level isolation, requiring cross-region architectures for site-level DR.
- ✗
Storage services are automatically replicated across public clouds.
Why it's wrong here
Storage replication is managed within OCI.
- ✗
You cannot deploy fault domains in a single-AD region.
Why it's wrong here
Fault domains exist within availability domains, including single-AD regions.
