Question

What are two advantages of EtherChannel? (Choose two.)

A) Configuring the EtherChannel interface provides consistency in the configuration of the physical links.
B) Load balancing occurs between links configured as different EtherChannels.
C) EtherChannel uses upgraded physical links to provide increased bandwidth.
D) Spanning Tree Protocol views the physical links in an EtherChannel as one logical connection.
E) Spanning Tree Protocol ensures redundancy by transitioning failed interfaces in an EtherChannel to a forwarding state.

Answer 1

EtherChannel provides advantages such as configuration consistency and improved STP performance by treating multiple physical links as one logical connection, thereby reducing management complexity and network disruptions.

Therefore, the correct answer is A) Configuring the EtherChannel interface provides consistency in the configuration of the physical links.

Step-by-step explanation:

Two advantages of EtherChannel include:

1. Configuring the EtherChannel interface provides consistency in the configuration of the physical links, which simplifies the complexity of network management and maintenance by treating multiple links as a single entity.
2. Spanning Tree Protocol views the physical links in an EtherChannel as one logical connection. This helps in avoiding loop issues that can cause network disruption, as STP will treat the EtherChannel as a single link, thus also reducing the number of STP instances required.

Options B and E are not correct since load balancing occurs across the links within the same EtherChannel, not between different EtherChannels, and STP does not provide redundancy by transitioning failed interfaces but prevents loops by blocking redundant paths.

Option C is also incorrect because EtherChannel doesn't use upgraded physical links; it aggregates existing ones to increase bandwidth.

Therefore, the correct answer is A) Configuring the EtherChannel interface provides consistency in the configuration of the physical links.
