The internal network of a company is very large and would like to subnet into smaller parts. From the options given below, the device that will not be used to separate LAN and still protect critical resources is
Answer: A
Correct answer: The modem between computers
Routers, firewalls and switches all divide a network into parts and control what passes between them. A modem converts signals for transmission over a line; it does not subnet anything or filter traffic, so it neither separates the LAN nor protects it.

Which of the following is not a network device?
Answer: C
Correct answer: Modem
Routers, switches and bridges all forward traffic between hosts or segments within a network. A modem converts between digital and analogue signals so that data can cross a telephone line; it adapts the signal rather than making forwarding decisions, which is why it is not counted among the network devices proper.

Every node on the network is connected through a central device is called _____ topology.
Answer: C
Correct answer: Star
In a star topology every node has its own link to a central hub or switch, so all traffic passes through that centre. That makes cabling simple and one node's failure harmless, at the cost of depending entirely on the central device.

Which of the following are unique characteristics of half-duplex Ethernet when compared to full-duplex Ethernet?
1. Half-duplex Ethernet operates in a shared collision domain.
2. Half-duplex Ethernet operates in a private collision domain.
3. Half-duplex Ethernet has higher effective throughput.
4. Half-duplex Ethernet has lower effective throughput.
Answer: C
Correct answer: 1 and 4
Half-duplex Ethernet cannot send and receive at once, so every station shares one collision domain and must use CSMA/CD to detect and recover from collisions. Full duplex has a separate path each way, so collisions cannot occur and collision detection is switched off.

Answer: B
Correct answer: Star
In bus and ring topologies a signal reaches every station, so both are broadcast arrangements. In a star the central device receives each transmission and passes it on only where it is needed, so it is not inherently broadcast.
