1Z0-1072-26 Networking Practice Question
You are designing an application that requires high availability across two Availability Domains (ADs). You want your OCI Public Load Balancer to span both ADs. Which configuration should you use?
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
✓
Select subnets in two different Availability Domains during load balancer creation.
When provisioning an OCI Public Load Balancer, you select a primary subnet in one AD and a secondary subnet in another AD to ensure high availability across ADs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Attach a NAT Gateway to both Availability Domains.
Why it's wrong here
NAT Gateways do not provide cross-AD load balancing.
- ✗
Configure an LPG between the two AD subnets.
Why it's wrong here
LPGs are for VCN-to-VCN peering, not subnets within the same VCN.
- ✓
Select subnets in two different Availability Domains during load balancer creation.
Why this is correct
Configuring primary and secondary subnets across ADs ensures high availability.
- ✗
Deploy two separate load balancers and use an Internet Gateway to load balance between them.
Why it's wrong here
An OCI load balancer natively spans ADs without needing multiple load balancers.
