Options- A. copy running backup
- B. copy running-config startup-config
- C. config mem
- D. wr mem Discuss
- 3. What is the main reason the OSI model was created?
Options- A. To create a layered model larger than the DoD model.
- B. So application developers can change only one layer's protocols at a time.

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: 12
Explanation:
Layer 2 switching creates individual collision domains.
Correct Answer: VTP is used to send VLAN information to switches in a configured VTP domain.
Explanation:
Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunking Protocol (VTP) is used to propagate VLAN information across a trunk link.
Correct Answer: show interface
Explanation:
The
show interface command shows the line, protocol, DLCI, and LMI information of an interface.
Correct Answer: A network that has only one entry and exit point.
Explanation:
Stub networks have only one connection to an internetwork. Only default routes can be set on a stub network or network loops may occur.
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.
