Welcome to Networking Quiz, Entry Level !!

Question 1. What frequency range is used for FM radio transmission?

Very Low Frequency : 3 kHz to 30 kHz

Low Frequency : 30 kHz to 300 kHz

High Frequency : 3 MHz to 30 MHz

Very High Frequency : 30 MHz to 300 MHz

Question 2. Which of the following is not a reason to use fiber-optic cables for point to point data transmission?

Need to assure data security.

Avoidance of ground loops.

Data-transfer rates too low to use metal cables.

Elimination of spark hazards.

Question 3. The geostationary satellite used for communication systems

rotates with the earth

remains stationary relative to the earth

is positioned over equator

all of the above

Question 4. When you ping the loopback address, a packet is sent where?

on the network

Down through the layers of the IP architecture and then up the layers again

Across the wire

through the loopback dongle

Question 5. Frames from one LAN can be transmitted to another LAN via the device

router

bridge

repeater

modem

Question 6. What makes optical fibers immune to EMI?

They transmit signals in as light rather than electric current.

They are too small for magnetic fields to introduce current in them.

Magnetic fields cannot penetrate the glass of the fiber.

They are readily sheilded by outer conductors in cable.

simplex

duplex

multiplex

half-duplex

Question 8. Which of the following layer protocols are responsible for user and the application programmer support such as passwords, resource sharing, file transfer and network management?

Layer 7 protocols

Layer 6 protocols

Layer 5 protocols

Layer 4 protocols

Question 9. What device separates a single network into two segments but lets the two segments appear as one to higher protocols?

switch

bridge

Gateway

Router

Question 10. Which of the following is used for modulation and demodulation?

modem

protocols

gateway

multiplexer
