5. What does the term "attenuation" mean in data communication?
- A.
Loss of signal strength as distance increases
- B.
Time for a signal to reach its destination
- C.
Leakage of signals from one cable pair to another
- D.
Strengthening of a signal by a networking device
Correct Answer
A. Loss of signal strength as distance increasesExplanation
Attenuation refers to the gradual decrease in signal strength as it travels over a distance in data communication. This can occur due to various factors such as resistance, interference, and impedance mismatch. As the signal travels farther, it experiences more resistance and interference, causing its strength to diminish. Therefore, the correct answer is "loss of signal strength as distance increases."Rate this question:

6. How many host addresses may be assigned on each subnetwork when using the 130.68.0.0 network address with a subnet mask of 255.255.248.0?
- A.
30
- B.
256
- C.
2046
- D.
2048
- E.
4094
Correct Answer
C. 2046Explanation
When using the subnet mask 255.255.248.0, it means that 13 bits are used for the network portion and 11 bits are used for the host portion. The formula to calculate the number of host addresses is 2^n - 2, where n is the number of bits in the host portion. So in this case, 2^11 - 2 equals 2046. Therefore, there may be 2046 host addresses assigned on each subnetwork when using the given network address and subnet mask.Rate this question:

- A.
Both host A and B would be successful
- B.
Host A would be successful, host B would fail
- C.
Host B would be successful, host A would fail
- D.
Both Host A and B would fail
Correct Answer
C. Host B would be successful, host A would failExplanation
Based on the IP configuration shown in the exhibit, Host A has an IP address of 192.168.1.10 with a subnet mask of 255.255.255.0, while Host B has an IP address of 192.168.2.10 with a subnet mask of 255.255.255.0. The subnet masks indicate that Host A and Host B are on different network segments, as the subnet masks define the network portion of the IP address. Therefore, Host A and Host B would not be able to communicate directly with each other outside of their respective network segments. Host B would be successful in communicating within its own network segment, but Host A would fail in communicating outside of its network segment.Rate this question:
