Oracle Cloud Infrastructure 2019 Developer Associate — Question 55

Why are two subnets required to create a public load balancer when additional subnets are often used for back-end servers? (Choose two.)

Answer options

• A. Routing is simpler when the load balancer is not in the same subnet as the back-end server.
• B. Performance is higher when more subnets are used.
• C. Additional subnets for back-end servers allow for separate route tables for these servers.
• D. Additional subnets for back-end servers allow for separate security lists for these servers.

Correct answer: B, D

Explanation

Option B is correct because having multiple subnets can lead to better resource distribution and performance improvements. Option D is also correct since additional subnets allow for implementing distinct security lists, which help manage security policies effectively. Options A and C are incorrect as they do not directly address the necessity of multiple subnets for a public load balancer.
