SRWE Module 6 -- Understanding EtherChannel Concepts

What is the primary purpose of configuring EtherChannel on a network switch?

• To increase the number of VLANs

• To aggregate multiple physical links into a single logical link

• To enable wireless connectivity

• To reduce the number of IP addresses

Which of the following is a benefit of using EtherChannel in a network?

• It reduces the need for network security

• It provides redundancy and load balancing

• It simplifies IP addressing

• It increases the number of available ports

When configuring EtherChannel, which protocol can be used to automatically negotiate the formation of a channel?

• STP

• LACP

• OSPF

• BGP

What steps should you take to ensure successful configuration of an EtherChannel?

• Enable STP on all ports, configure IP addresses, and set VLANs

• Configure the same speed and duplex settings, and use the same EtherChannel protocol

• Enable all ports, configure different speeds, and use different EtherChannel protocols

• Configure different VLANs on each port and enable DHCP

How does EtherChannel improve network performance in terms of bandwidth utilization?

• By reducing the number of switches needed

• By aggregating bandwidth into a single logical link

• By increasing the number of IP addresses available

• By enabling faster wireless connections

Which of the following statements best describes the role of the Port Aggregation Protocol (PAgP) in EtherChannel?

• It is a Cisco proprietary protocol to automatically negotiate EtherChannel

• It is a Cisco proprietary protocol for routing between VLANs

• It is a Cisco proprietary protocol used to encrypt data on a network

A network administrator is planning to implement EtherChannel on a network. What considerations should they take into account to ensure compatibility between switches?

• Ensure all switches are from the same manufacturer

• Ensure all ports have the same VLAN configuration and EtherChannel protocol

• Ensure all switches have the same IP address and are configured with PaGP

• Ensure all ports are configured for wireless access using LACP

What is a potential drawback of using EtherChannel in a network configuration?

• It increases the complexity of IP addressing

• It can create a single point of failure if not properly configured

• It reduces the number of available ports

• It limits the number of VLANs that can be used

In a network using EtherChannel, what happens if one of the physical links in the channel fails?

• The entire EtherChannel fails

• The EtherChannel continues to operate with reduced bandwidth

• All traffic is rerouted to a different VLAN

• The switch shuts down

How does the use of EtherChannel affect the Spanning Tree Protocol (STP) in a network?

• It disables STP on all ports

• It treats the EtherChannel as a single link, reducing the number of STP calculations

• It requires a separate STP instance for each link in the EtherChannel

• It increases the number of STP calculations
