You are deploying a highly available web application in Oracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs).
How many subnets should you create to deliver a secure, highly available application?
For a highly available web application using a public load balancer with back-end web servers distributed across all three availability domains in Oracle Cloud Infrastructure, you should create two subnets in total: one regional private subnet to host the back-end web servers and one regional public subnet to host the public load balancer. This setup ensures that the load balancer, which needs to interact with the internet, resides in a public subnet, while the back-end servers remain secure in a private subnet.
answer is A. load balancer is the interface between internet and the backend web servers in order for it to distribute the load accordingly so it should be in a public subnet
C is incorrect because the load balancer must be public, so the private subnets are out of the question. A.
A is correct
A is correct .
The Correct Answer is A, not C. To secure the backend, put it in a private subnet, and the LBAS on Public Subnet since it is must access from the internet.
A is correct Cause LB in Public Subnet and Web Servers in Private so two subnets in total
A is the answer https://docs.oracle.com/en-us/iaas/Content/Balance/Concepts/balanceoverview.htm
A is correct
A "With a regional subnet, the Load Balancing service creates a primary load balancer and a standby load balancer, each in a different availability domain"
A is correct, one private subnet for web app servers for securing your app and one public for the load balancer.
