Networking Basics problems
- 1. How many collision domains are created when you segment a network with a 12-port switch?
Options- A. 1
- B. 2
- C. 5
- D. 12 Discuss
Correct Answer: 12
Explanation:
Layer 2 switching creates individual collision domains.
- 2. 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.
- C. So different networks could communicate.
- D. So Cisco could use the model. Discuss
Correct Answer: So different networks could communicate.
Explanation:
The primary reason the OSI model was created was so that different networks could inter-operate.
- 3. What command is used to create a backup configuration?
Options- A. copy running backup
- B. copy running-config startup-config
- C. config mem
- D. wr mem Discuss
Correct Answer: copy running-config startup-config
Explanation:
The command to back up the configuration on a router is
copy running-config startup-config.
- 4. If your router is facilitating a CSU/DSU, which of the following commands do you need to use to provide the router with a 64000bps serial link?
Options- A. RouterA(config)#bandwidth 64
- B. RouterA(config-if)#bandwidth 64000
- C. RouterA(config-if)#clock rate 64
- D. RouterA(config-if)#clock rate 64000 Discuss
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.
- 5. In a network with dozens of switches, how many root bridges would you have?
Options- A. 1
- B. 2
- C. 5
- D. 12 Discuss
Correct Answer: 1
Explanation:
You should have only one root bridge per network.
- 6. What command will display the line, protocol, DLCI, and LMI information of an interface?
Options- A. sh pvc
- B. show interface
- C. show frame-relay pvc
- D. show run Discuss
Correct Answer: show interface
Explanation:
The
show interface command shows the line, protocol, DLCI, and LMI information of an interface.
- 7. What is a stub network?
Options- A. A network with more than one exit point.
- B. A network with more than one exit and entry point.
- C. A network with only one entry and no exit point.
- D. A network that has only one entry and exit point. Discuss
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.
- 8. You have 10 users plugged into a hub running 10Mbps half-duplex. There is a server connected to the switch running 10Mbps half-duplex as well. How much bandwidth does each host have to the server?
Options- A. 100 kbps
- B. 1 Mbps
- C. 2 Mbps
- D. 10 Mbps Discuss
Correct Answer: 10 Mbps
Explanation:
Each device has 10 Mbps to the server.
- 9. What does a VLAN do?
Options- A. Acts as the fastest port to all servers.
- B. Provides multiple collision domains on one switch port.
- C. Breaks up broadcast domains in a layer 2 switch internetwork.
- D. Provides multiple broadcast domains within a single collision domain. Discuss
Correct Answer: Breaks up broadcast domains in a layer 2 switch internetwork.
Explanation:
VLANs break up broadcast domains at layer 2.
- 10. What protocols are used to configure trunking on a switch?
- VLAN Trunking Protocol
- VLAN
- 802.1Q
- ISL
Options- A. 1 and 2
- B. 3 and 4
- C. 1 only
- D. 2 only Discuss
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.
