Correct answer: A
I is correct: Hexadecimal number system → Base sixteen representation. It uses 0–9 and A–F. II is correct: Binary number system → Base two representation. It uses the digits zero and one.
Correct answer: C
I is correct: MAC address → Link-layer hardware interface identifier. It is used on local network segments. II is incorrect: Modem → Converts signals for a communication link. Its name derives from modulation and demodulation.
Correct answer: D
Packets can be routed over shared links.
Correct answer: C
I is correct: Latency → Delay before or during delivery of data. A high-capacity link can still have high latency. II is incorrect: Bandwidth → Data-carrying capacity of a communication channel. It is often expressed as bits per second.
Correct answer: D
It interprets web documents for the user.
Correct answer: B
I is correct: Cookie → Small piece of site-related data stored by a client. It can support session state and preferences. II is correct: TCP → Reliable ordered transport protocol. It uses acknowledgements and retransmission.
Correct answer: D
It is accessed through a browser or another client.
Correct answer: A
I is incorrect: Router → Forwards packets between networks. It chooses paths using routing information. II is correct: MAC address → Link-layer hardware interface identifier. It is used on local network segments.
Correct answer: D
Typical Ethernet switching uses MAC addresses.
Correct answer: C
I is incorrect: Modem → Converts signals for a communication link. Its name derives from modulation and demodulation. II is correct: Packet switching → Dividing data into packets for network transmission. Packets can be routed over shared links.
Correct answer: D
I is correct: Switch → Connects devices within a local network and forwards frames. Typical Ethernet switching uses MAC addresses. II is incorrect: UDP → Connectionless datagram transport protocol. It does not itself guarantee delivery or ordering.
Correct answer: A
It is often expressed as bits per second.
Correct answer: C
I is incorrect: DHCP → Automatically supplies network configuration. It can assign IP addresses and related settings. II is incorrect: URL → Address identifying a web resource and access scheme. It can include a scheme, host, path and query.
Correct answer: B
It is used on local network segments.
Correct answer: D

Correct answer: B
It can support session state and preferences.
Correct answer: A
I is incorrect: Search engine → Service indexing and finding web information. It is accessed through a browser or another client. II is incorrect: TCP → Reliable ordered transport protocol. It uses acknowledgements and retransmission.
