Question

Which of the following is a protocol that allows you to bundle multiple physical interfaces (for example, Ethernet switch interfaces) into a single logical interface?

a) HSRP (Hot Standby Router Protocol)
b) GLBP (Gateway Load Balancing Protocol)
c) VRRP (Virtual Router Redundancy Protocol)
d) EtherChannel

Answer 1

EtherChannel is the protocol that allows you to bundle multiple physical interfaces into a single logical interface.

Step-by-step explanation:

The protocol that allows you to bundle multiple physical interfaces into a single logical interface is EtherChannel.

EtherChannel is a technology used in networking that combines multiple physical interfaces (such as Ethernet switch interfaces) into a logical channel. This allows for increased bandwidth, redundancy, and load balancing.

For example, if you have four physical Ethernet switch interfaces, you can use EtherChannel to bundle them together into a single logical interface, resulting in greater speed and reliability.
