Correct answer: B
Correct answer: 3 and 4.
IEEE 802.1Q and ISL are trunk encapsulation methods. They identify VLAN-tagged traffic as it crosses a trunk link between switches.
VTP: VLAN Trunking Protocol distributes VLAN database information, but it is not the trunk encapsulation protocol itself.
VLAN: A VLAN is the logical network segment, not an encapsulation protocol.
Therefore, the protocols used for trunk encapsulation are 802.1Q and ISL.
