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
Explanation:
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.
