1. Imagine that a switch connects through an Ethernet cable to a router, and the router’s host name is Eliot. Which of the following commands could tell you information about the IOS version on Eliot without establishing a Telnet connection to Eliot? (Choose two answers.)
a. show neighbors Eliot
b. show cdp
c. show cdp neighbors
d. show cdp neighbors Eliot
e. show cdp entry Eliot
f. show cdp neighbors detail
2. A switch is cabled to a router whose host name is Bobby. Which of the following CDP commands could identify Bobby’s model of hardware? (Choose two answers.)
a. show neighbors
b. show neighbors Bobby
c. show cdp
d. show cdp interface
e. show cdp neighbors
f. show cdp entry Bobby
3. The output of the show interfaces status command on a 2960 switch shows interface Fa0/1 in a “disabled” state. Which of the following is true about interface Fa0/1? (Choose three answers.)
a. The interface is configured with the shutdown command.
b. The show interfaces fa0/1 command will list the interface with two status codes of
administratively down and line protocol down.
c. The show interfaces fa0/1 command will list the interface with two status codes of
up and down.
d. The interface cannot currently be used to forward frames.
e. The interface can currently be used to forward frames.
4. Switch SW1 uses its Gigabit 0/1 interface to connect to switch SW2’s Gigabit 0/2 interface. SW2’s Gi0/2 interface is configured with the speed 1000 and duplex full commands.
SW1 uses all defaults for interface configuration commands on its Gi0/1 interface. Which of the following are true about the link after it comes up? (Choose two answers.)
a. The link works at 1000 Mbps (1 Gbps).
b. SW1 attempts to run at 10 Mbps because SW2 has effectively disabled IEEE standard
autonegotiation.
c. The link runs at 1 Gbps, but SW1 uses half-duplex and SW2 uses full-duplex.
d. Both switches use full-duplex.
5. The following line of output was taken from a show interfaces fa0/1 command:
Full-duplex, 100Mbps, media type is 10/100BaseTX
Which of the following are true about the interface? (Choose two answers.)
a. The speed was definitely configured with the speed 100 interface subcommand.
b. The speed might have been configured with the speed 100 interface
subcommand.
c. The duplex was definitely configured with the duplex full interface
subcommand.
d. The duplex might have been configured with the duplex full interface
subcommand.
6. Which of the following commands list the MAC address table entries for MAC addresses configured by port security? (Choose two answers.)
a. show mac address-table dynamic
b. show mac address-table
c. show mac address-table static
d. show mac address-table port-security
7. On a Cisco Catalyst switch, you issue a show mac address-table command. Which of the following answers list information you would likely see in most lines of output? (Choose two answers.)
a. A MAC address
b. An IP address
c. A VLAN ID
d. Type (broadcast, multicast, or unicast)
8. Layer 2 switches SW1 and SW2 connect through a link, with port G0/1 on SW1 and port G0/2 on SW2. The network engineer wants to use 802.1Q trunking on this link. The show interfaces g0/1 switchport command on SW1 shows the output listed here:
SW1# show interfaces gigabit0/1 switchport
Name: Gi0/1
Switchport: Enabled
Administrative Mode: trunk
Operational Mode: trunk
Which of the following must be true on switch SW2’s G0/2 port?
a. The operational state per the show interfaces switchport command must be “trunk.”
b. The administrative state per the show interfaces switchport command must be
“trunk.”
c. SW2 must use the switchport mode trunk configuration command on G0/2, or the
link will not use trunking.
d. SW2 can use the switchport mode dynamic auto configuration command as one
option to make the link use trunking.
