1Z0-1085-26 Getting Started With Oci Practice Question
Which THREE statements are true regarding the architecture and design principles of OCI Availability Domains (ADs) and Regions?
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
✓
Some OCI regions are built with a single availability domain, while others contain multiple availability domains.
OCI regions contain ADs, ADs are isolated from each other, and regions are independent geographic areas.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
An availability domain can span across multiple geographic countries to maximize data locality.
Why it's wrong here
Availability domains are local to a specific region and do not span across multiple countries.
- ✗
Availability domains share power, cooling, and physical security infrastructure to reduce operational overhead.
Why it's wrong here
Availability domains are intentionally designed not to share infrastructure such as power or cooling to prevent correlated failures.
- ✓
Some OCI regions are built with a single availability domain, while others contain multiple availability domains.
Why this is correct
OCI regions can be single-AD or multi-AD regions depending on customer demand and regional architecture.
- ✓
OCI regions are completely independent of other regions and are separated by vast geographic distances.
Why this is correct
Regions are independent and geographically separated for disaster recovery purposes.
- ✓
Availability domains within the same region are connected by a high-bandwidth, low-latency network.
Why this is correct
ADs are engineered with high-speed, low-latency network connectivity to allow synchronous replication and high availability.
