by organizing the network to control traffic patterns*

by limiting the size of failure domains

6. As the network administrator you have been asked to implement EtherChannel on the corporate network. What does this configuration consist of?

grouping multiple physical ports to increase bandwidth between two switches*

7. Which technology is required when switched networks are designed to include redundant links?

Spanning Tree Protocol*

virtual LANs

link aggregation

show flash

show startup-config*

show NVRAM

show version

show running-config*

11. A network administrator is planning redundant devices and cabling in a switched network to support high availability. Which benefit will implementing the Spanning Tree Protocol provide to this design?

Redundant paths can be available without causing logical Layer 2 loops.*

Multiple physical interfaces can be combined into a single EtherChannel interface.

Faster convergence is available for advanced routing protocols.

Network access can be expanded to support both wired and wireless devices.

12. Which two requirements must always be met to use in-band management to configure a network device? (Choose two.)

at least one network interface that is connected and operational*

a terminal emulation client

a direct connection to the console port
