- Correct Answer
- A network that has only one entry and exit point.
ExplanationStub networks have only one connection to an internetwork. Only default routes can be set on a stub network or network loops may occur. - 1. What command will display the line, protocol, DLCI, and LMI information of an interface?

Correct Answer: show interface
Explanation:
The
show interface command shows the line, protocol, DLCI, and LMI information of an interface.
Correct Answer: 1
Explanation:
You should have only one root bridge per network.
Correct Answer: RouterA(config-if)#clock rate 64000
Explanation:
The
clock rate command is two words, and the speed of the line is in bps.
Correct Answer: copy running-config startup-config
Explanation:
The command to back up the configuration on a router is
copy running-config startup-config.
Correct Answer: So different networks could communicate.
Explanation:
The primary reason the OSI model was created was so that different networks could inter-operate.
Correct Answer: 10 Mbps
Explanation:
Each device has 10 Mbps to the server.
Correct Answer: Breaks up broadcast domains in a layer 2 switch internetwork.
Explanation:
VLANs break up broadcast domains at layer 2.
Correct Answer: 3 and 4
Explanation:
VTP is not right because it has nothing to do with trunking except that it sends VLAN information across a trunk link. 802.1Q and ISL are used to configure trunking on a port.
Correct Answer: 192.168.168.129-190
Explanation:
256 - 192 = 64. 64 + 64 = 128. 128 + 64 = 192. The subnet is 128, the broadcast address is 191, and the valid host range is the numbers in between, or 129-190.
Correct Answer: ICMP
Explanation:
ICMP is the protocol at the Network layer that is used to send messages back to an originating router.
