Networking Miscellaneous - Practice Test

[#126] Which of the following characteristic(s) is/are suited to the PSS applications?

(A) bursty traffic and low communications intensity

(B) widely dispersed terminals and access to international packets switched services

(C) Multiple remote host or applications accessed by a single local access circuit terminal and circuit

(D) All of the above

Correct Answer

(D) All of the above

[#127] Because the configuration infor-mation for a DHCP client is received dynamically, you must use which utility to read the current configuration to verify the settings?

(A) PING

(B) TRACERT

(C) ARP

(D) IPCONFIG

Correct Answer

(D) IPCONFIG

[#128] The slowest transmission speeds are those of

(A) twisted-pair wire

(B) coaxial cable

(C) fiber-optic cable

(D) microwaves

(E) twisted-pair wire

(F) coaxial cable

(G) fiber-optic cable

(H) microwaves

Correct Answer

(A) twisted-pair wire
(E) twisted-pair wire

Explanation

Solution: Twisted-pair wire has the slowest transmission speeds among the given options. It is commonly used in telephone networks and older data communication networks. Coaxial cable has higher transmission speeds compared to twisted-pair wire and is used in cable TV and internet services. Fiber-optic cable offers the highest transmission speeds as it uses light to transmit data. Microwaves are used for wireless transmission and offer higher speeds compared to twisted-pair wire.

[#129] A noiseless 3 KHz Channel transmits bits with binary level signals. What is the maximum data rate?

(A) 3 Kbps

(B) 6 Kbps

(C) 12 Kbps

(D) 24 Kbps.

Correct Answer

(B) 6 Kbps

[#130] Carrier is

(A) One or more conductors that serve as a common connection for a related group of devices

(B) a continuous frequency capable of being modulated or impressed with a second signal

(C) the condition when two or more sections attempt to use the same channel at the same time

(D) a collection of interconnected functional units that provides a data communications service among stations attached to the network

Correct Answer

(B) a continuous frequency capable of being modulated or impressed with a second signal
