What types of connections does the VEN open for communication?

The Virtual Enforcement Node (VEN) primarily establishes connections over specific ports to facilitate communication with its management components and other nodes in the network. The correct answer, which includes ports 8443 TCP and 3444 TCP, accurately reflects the communication requirements for Illumio's core functionality.

Port 8443 TCP is used for secure communication with the Illumio Policy Compute Engine (PCE), enabling the VEN to receive policy updates and configuration information. This secure channel is vital for ensuring that all communications are protected through encryption.

Port 3444 TCP is also employed for communication purposes within the Illumio framework. It is utilized for sending telemetry data and other necessary information back to the Policy Compute Engine, allowing for real-time visibility and management of security policies.

Both ports play crucial roles in ensuring that the VEN can effectively operate, synchronize, and enforce policies within the environment, highlighting the importance of these specific connection types for proper Illumio functionality.
