1Z0-1085-26 Getting Started With Oci Practice Question
You are deploying a distributed database cluster that requires three nodes to be isolated from one another regarding underlying infrastructure failures. The chosen OCI region has only one Availability Domain. How should you provision the database 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
✓
Deploy each node in a separate Fault Domain (FD-1, FD-2, and FD-3) within the single Availability Domain.
When an OCI region has only one Availability Domain, you achieve high availability by placing instances across three distinct Fault Domains within that AD.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy the nodes in the same Fault Domain and configure OCI Compute Auto-Scaling.
Why it's wrong here
Auto-scaling does not prevent hardware failure in a single fault domain.
- ✗
Deploy the nodes across three different OCI regions using asynchronous database links.
Why it's wrong here
While cross-region deployment is valid for DR, single-AD fault isolation is handled via fault domains.
- ✗
Deploy all three nodes in the same Fault Domain to maximize internal rack-level network performance.
Why it's wrong here
Deploying all nodes in a single fault domain creates a single point of failure for rack power or switch issues.
- ✓
Deploy each node in a separate Fault Domain (FD-1, FD-2, and FD-3) within the single Availability Domain.
Why this is correct
Distributing the three nodes across FD-1, FD-2, and FD-3 ensures that no single hardware failure or maintenance event takes down more than one node.
