Networking Concepts Quiz

What is the function of the Transport layer in the TCP/IP stack?

• To transmit data over the physical medium

• To provide end-to-end communication between applications

• To route data packets between networks

• To manage data flow control and error correction

Which network technology commonly uses packet switching?

• Traditional landline telephone networks

• Dial-up internet connections

• Ethernet LANs

• ATM networks

What is the primary function of a router in a network?

• To connect devices within the same local network

• To connect different networks and forward data between them

• To translate between different network protocols

• To provide secure access to the network

Which layer of the OSI model is responsible for routing and addressing?

• Data Link Layer

• Network Layer

• Transport Layer

• Application Layer

Which TCP/IP protocol is responsible for resolving domain names to IP addresses?

• HTTP

• DNS

• FTP

• SNMP

In packet switching, what happens if a packet encounters congestion on the network?

• The packet is discarded

• The packet is rerouted

• The packet is fragmented

• The packet is prioritized

What is the purpose of the TCP/IP protocol suite?

• To establish a physical connection between devices

• To ensure data integrity during transmission

• To facilitate communication between computers on a network

• To encrypt sensitive information

What is the main difference between packet switching and circuit switching?

• Packet switching establishes a dedicated connection for the duration of the transmission, while circuit switching does not.

• Packet switching breaks data into small packets for transmission, while circuit switching sends data in a continuous stream.

• Packet switching is faster but less reliable, while circuit switching is slower but more reliable.

• Packet switching is used for analog signals, while circuit switching is used for digital signals.

Which protocol is used to transfer files over the internet?

• TCP

• IP

• FTP

• HTTP

Which protocol is used for email transmission in the TCP/IP suite?

• SMTP

• FTP

• HTTP

• Telnet
