Question 1 of 30

A cloud operations team is tasked with securing a multi-tier application deployed in Oracle Cloud Infrastructure. The application consists of a web tier, application tier, and database tier, each running on separate instances within the same subnet. The team needs to ensure that the web tier can communicate with the application tier, but the application tier should not be directly accessible from the internet. Additionally, they want to allow the application tier to communicate with the database tier while restricting access to specific IP addresses. Which approach would best meet these requirements while maintaining flexibility and ease of management?

Implement Network Security Groups for each tier to define specific rules for inbound and outbound traffic.

Use Security Lists to apply broad rules to the entire subnet, ensuring all instances can communicate as needed.

Create a combination of Security Lists and Network Security Groups to manage access at both the subnet and instance levels.

Configure a single Security List that allows all traffic between the tiers while blocking external access to the application tier.
