Oracle Cloud Infrastructure Foundations Associate: VCN Subnets Route Tables and NSGs

Networking is a core component of Oracle Cloud Infrastructure (OCI), enabling secure and scalable communication between cloud resources.In this course, learn how OCI Networking is built around Virtual Cloud Networks (VCNs) and explore the roles of subnets, route tables, and security constructs. Next, discover how subnets logically divide a VCN, how route tables manage traffic flow, and how security lists enforce subnet-level firewall rules. Finally, explore security rules and network security groups (NSGs) and how they provide flexible, instance-level protection.This course is part of a series designed to prepare learners for the Oracle Cloud Infrastructure 2025 Certified Foundations Associate (1Z0-1085-25) certification.
