1. Identify the factors that contribute to congestion on an Ethernet LAN. (Choose three.)
-- *** improper placement of enterprise level servers
-- *** addition of hosts to a physical segment
-- replacement of hubs with workgroup switches
-- *** increasing use of bandwidth intensive network applications
-- creation of new collision domains without first adding network hosts
-- migration to full-duplex Ethernet within the LAN
2. Which of the following are examples of TCP/IP application layer protocols? (Choose three.)
-- *** a terminal emulation protocol that supports remote console connections with various network devices
-- a protocol created by IBM that makes it easier for mainframes to connect to remote offices
-- *** a protocol responsible for transporting electronic mail on TCP/IP networks and the Internet
-- a protocol that controls the rate at which data is sent to another computer
-- *** a protocol that exchanges network management information between a network device and a management console
3. Which of the following eliminates switching loops?
-- hold-down timers
-- poison reverse
-- *** spanning tree protocol
-- time to live
-- split horizon protocol
4. The show cdp neighbors command is a very useful network troubleshooting tool. Using the output in the graphic, select the statements
that are true. (Choose two.)
-- CDP operates at the network layer of the OSI model.
-- *** The output of this command displays information about directly connected Cisco devices only.
-- The switch is attached to the SanJose1 FastEthernet0/21 interface.
-- SanJose1 is running CDP version 12.0.
-- SanJose1 has two fully operational, cdp-enabled Cisco switches directly connected to it.
-- *** SanJose2 is a 2600 series router running several routed protocols
5. A network administrator can ping the Denver router, but gets a 'Password Required but None Set' message when trying to connect
remotely via Telnet. Which command sequence must be applied to the Denver router to allow remote access?
-- Router(config)# line console 0
Router(config-line)# login
Router(config-line)# password cisco
-- *** Router(config)# line vty 0 4
*** Router(config-line)# login
*** Router(config-line)# password cisco
-- Router(config)# line virtual terminal
Router(config-line)# enable login
6. Router(config-line)# password cisco
-- Router(config)# line vty 0 4
Router(config-line)# enable secret
Router(config-line)# password cisco
-- Router(config)# enable secret cisco
Router(config)# enable cisco
