3V0-24.25 VCF 9.0 Antrea CNI NetworkPolicies Explained

About this video

Preparing for the VMware 3V0-24.25 VCF 9.0 Architect Exam requires understanding how Kubernetes security boundaries are actually built. In this video, we explore Objective 2.6 and break down how Antrea CNI NetworkPolicies provide Layer 3 and Layer 4 workload isolation inside a VKS environment. You will learn: How Antrea CNI provides Pod networking and IP connectivity Why basic network reachability does not equal security How Default-Deny NetworkPolicies create a secure baseline How label-based rules allow controlled application communication How to restrict traffic by source Pod, destination workload, and TCP port How to validate network isolation using Kubernetes troubleshooting commands A common exam mistake is assuming that connectivity problems are always caused by certificates, applications, or external firewalls. In a cloud-native environment, security failures often begin at the workload networking layer. The 3V0-24.25 exam tests whether you understand how Kubernetes networking, micro-segmentation, and security policies work together. By the end of this module, you will have a practical framework for designing and troubleshooting Antrea-based network isolation in VCF environments. Next, we will move higher in the security stack and examine private registry access, Harbor integration, and certificate trust troubleshooting. #3V0-2425 #VCF9 #VMwareCertification
