What is the appropriate file format for Kubernetes applications?
In Kubernetes, configuration files are typically written in YAML (.yaml) format. YAML (Yet Another Markup Language) is preferred due to its readability and ease of use for defining complex data structures like those required for Kubernetes deployments. Kubernetes uses these YAML files to define resources such as pods, services, and deployments.

Why are VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster problematic for protecting containerized workloads?
Visibility into application-level cluster traffic:
VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster lack the necessary visibility into the traffic and communications occurring at the application level within the cluster. This limitation impedes their ability to effectively protect containerized workloads.

How must a Palo Alto Networks Next-Generation Firewall (NGFW) be configured in order to secure traffic in a Cisco ACI environment?
The Palo Alto Networks Next-Generation Firewall must be integrated into the Layer 3 underlay network to secure traffic within a Cisco ACI environment.
Reference: Integration documentation for Cisco ACI and Palo Alto Networks indicates the necessity of Layer 3 integration for policy enforcement and traffic management.

Which offering inspects encrypted outbound traffic?
TLS decryption is the feature that inspects encrypted outbound traffic. By decrypting TLS/SSL traffic, the firewall can inspect the content for threats and enforce security policies. This is crucial for preventing malware and other threats that might hide within encrypted traffic.

How does a CN-Series firewall prevent exfiltration?
The CN-Series firewall prevents data exfiltration by inspecting the content of outbound traffic. It uses advanced security features, such as threat prevention and data loss prevention (DLP), to detect and block suspicious activities and unauthorized data transfers, ensuring sensitive data remains within the secure environment.
