A network engineer must implement Ethernet links that are capable of transporting frames and IP traffic for different broadcast domains that are mutually isolated.
Consider that this is a multivendor environment. Which Cisco IOS switching feature can be used to achieve the task?

A. PPP encapsulation with a virtual template

B. Link Aggregation Protocol at the access layer

C. dot1q VLAN trunking

D. Inter-Switch Link








 

Suggested Answer: C

Here the question asks for transporting "frames and IP traffic for different broadcast domains that are mutually isolated" which is basically a long way of saying
VLANs so trunking is needed to carry VLAN information. There are 2 different methods for trunking, 802.1Q and ISL. Of these, only 802.1Q is supported by multiple vendors since ISL is a Cisco proprietary protocol.
