802.3bz is a standard for Ethernet over twisted pair at speeds of 2.5 and 5 Gbit/s. These use the same cabling as the ubiquitous Gigabit Ethernet, yet offer higher speeds. The resulting standards are named 2.5GBASE-T and 5GBASE-T.

Option A: 2.5Gb and 5Gb Ethernet ports

This is because option A shows how to identify the speed of an Ethernet port based on its name and the standard it supports.  A port that supports 2.5GBASE-T or 5GBASE-T is a multi-gigabit port that can operate at speeds of up to 2.5 Gbit/s or 5 Gbit/s over twisted pair cables 2 3 .

Therefore, option A is correct.

PAPI is the protocol that is used to establish tunnels between the CX switch and the Aruba Gateway for Dynamic Segmentation 1 .  By default, PAPI uses a simple checksum to verify the integrity of the messages, but it does not encrypt the payload 2 . This could expose the network to spoofing or replay attacks by malicious actors.  To address this situation, the administrator must enable Enhanced PAPI security, which uses AES-256 encryption and HMAC-SHA1 authentication to protect the tunnel traffic 2 .  Enhanced PAPI security can be enabled on the CX switch by using the command  system papi enhanced-security enable 3 . This will ensure that the tunnels built between the CX switch and the Aruba Gateway are encrypted and authenticated.
