Trunking Questions 2

Question 1

Question 2

Question 3

Question 4


From the “show mac address-table” output, we see FastEthernet0/1 can receive traffic from multiple VLANs -> it is configured as a trunk. Also from the “show cdp neighbors” output, we see Fa0/1 of this switch is connecting to Switch2 so it is configured as a trunk.

There are two MAC addresses learned from FastEthernet0/5 while FastEthernet0/5 is not configured as trunk (only Fa0/2 & Fa0/3 are configured as trunk links) -> a hub is used on this port.

Question 5


Dynamic Trunking Protocol (DTP) is a Cisco proprietary protocol for negotiating trunking on a link between two devices and for negotiating the type of trunking encapsulation (802.1Q) to be used.

    Q1 – dynamic desirable is the only DTP mode listed that will connect to dynamic auto

    Q2 – native vlans are untagged on trunk ports

    Q3 – vtp is not configured so A will not work — B is the only other correct answer
