Options- A. 2.4Gbps
- B. 5Gbps
- C. 2.4GHz
- D. 5GHz Discuss
- 2. How many non-overlapping channels are available with 802.11b?
Options- A. 3
- B. 12
- C. 23
- D. 40 Discuss
- 3. What is the maximum number of IP addresses that can be assigned to hosts on a local subnet that uses the 255.255.255.224 subnet mask?
Options- A. 14
- B. 15
- C. 16
- D. 30 Discuss
- 4. What are two purposes for segmentation with a bridge?
- To add more broadcast domains.
- To create more collision domains.
- To add more bandwidth for users.
- To allow more broadcasts for users.
Options- A. 1 only
- B. 2 and 3
- C. 2 and 4
- D. 4 only Discuss
- 5. Why does the data communication industry use the layered OSI reference model?
- It divides the network communication process into smaller and simpler components, thus aiding component development, design, and troubleshooting.
- It enables equipment from different vendors to use the same electronic components, thus saving research and development funds.
- It supports the evolution of multiple competing standards and thus provides business opportunities for equipment manufacturers.
- It encourages industry standardization by defining what functions occur at each layer of the model.
Options- A. 1 only
- B. 1 and 4
- C. 2 and 3
- D. 3 only Discuss

- The command is used to establish a static route.
- The default administrative distance is used.
- The command is used to configure the default route.

Correct Answer: 5GHz
Explanation:
The IEEE 802.11a standard runs in the 5GHz RF range.
Correct Answer: 3
Explanation:
The IEEE 802.11b standard provides 3 non-overlapping channels.
Correct Answer: 30
Explanation:
A /27 (255.255.255.224) is 3 bits on and 5 bits off. This provides 8 subnets, each with 30 hosts. Does it matter if this mask is used with a Class A, B, or C network address? Not at all. The number of host bits would never change.
Correct Answer: 2 and 3
Explanation:
Bridges break up collision domains, which allow more bandwidth for users.
Correct Answer: 1 and 4
Explanation:
The main advantage of a layered model is that it can allow application developers to change aspects of a program in just one layer of the layer model's specifications.
Advantages of using the OSI layered model include, but are not limited to, the following:
It divides the network communication process into smaller and simpler components, thus aiding compo- nent development, design, and troubleshooting;
it allows multiple-vendor development through standardization of network components;
it encourages industry standardization by defining what functions occur at each layer of the model;
it allows various types of network hardware and software to communicate;
Correct Answer: Proxy ARP
Explanation:
Proxy ARP can help machines on a subnet reach remote subnets without configuring routing or a default gateway.
Correct Answer: 1 and 2
Explanation:
Although answer D almost seems right, it is not; the mask is the mask used on the remote network, not the source network. Since there is no number at the end of the static route, it is using the default administrative distance of 1.
Correct Answer: 0x2102
Explanation:
All Cisco routers have a default configuration register setting of
0x2102, which tells the router to load the IOS from flash memory and the configuration from NVRAM.
Correct Answer: 1 and 3
Explanation:
No DR is assigned on any type of point-to-point link. No DR/BDR is assigned on the NBMA point-to-multipoint due to the hub/spoke topology. DR and BDR are elected on broadcast and non-broadcast multi-access networks. Frame Relay is a non-Broadcast Multi-Access (NBMA) network by default.
Correct Answer: You must use the terminal monitor command.
Explanation:
To see console messages through your Telnet session, you must enter the
terminal monitor command.
