Cisco® 300-620 Exam Practice Questions (P. 2)

GPT-4o - Answer

Dynamic Endpoint Attach, as highlighted in many Cisco resources, streamlines network administration by automatically configuring firewall ACLs when new endpoints are attached to an EPG. This feature ensures your security settings keep pace with changes in network architecture, improving both security and efficiency in network operations.

GPT-4o - Answer

In implementing Cisco ACI using 802.1p ports on 9396PX leaf switches, traffic tagged with IEEE 802.1q can utilize VLAN 0 as a priority tag, allowing the frame priority bits to control traffic processing, essentially ignoring the VLAN ID. This configuration enables efficient traffic management with priority distinctions while avoiding physical VLAN configuration complexities on shared interfaces where multiple EPGs might exist. Hence, choosing VLAN 0 for traffic under IEEE 802.1p on these specific models aligns with Cisco's design guidelines for effective network traffic management in a multi-EPG environment.
