1Multiple choice1 markProtocols & Layers Swap Remove

The TCP/IP model is made up of four layers.

Identify the layer that is responsible for routing packets.

[1 mark]
  • AApplication
  • BInternet
  • CLink
  • DTransport
Mark scheme
  • B Internet (1)
  • The only correct answer is B. The correct answer is Internet.
  • A is not correct because the application layer creates data for applications such as web browsers and does not route packets
  • C is not correct because the link layer sends data over physical hardware using MAC addresses and does not route packets
  • D is not correct because the transport layer sets up the connection between two computers and reassembles the packets
Example answers and how they were marked
Full marks1/1

B Internet

Why: The internet layer is responsible for routing packets (1).

No marks0/1

A Application

Why: The application layer creates data for applications such as web browsers and does not route packets (0).

No marks0/1

C Link

Why: Confuses the link layer with the internet layer: the link layer sends data over physical hardware using MAC addresses and does not route packets (0).

2Multiple choice1 markAddressing Swap Remove

Data is sent across the internet in packets.

Identify the device that uses IP addresses to forward packets from one network to another.

[1 mark]
  • AHub
  • BNetwork interface card
  • CRouter
  • DSwitch
Mark scheme
  • C Router (1)
  • The only correct answer is C. The correct answer is router.
  • A is not correct because a hub sends data to every device on the network
  • B is not correct because a network interface card connects a device to a network
  • D is not correct because a switch forwards data within a single network using MAC addresses
Example answers and how they were marked
Full marks1/1

C Router

Why: Correct option (1): a router uses IP addresses to forward packets between networks.

No marks0/1

D Switch

Why: A switch forwards data within one network using MAC addresses, not between networks (mark scheme line D), so no mark.

No marks0/1

A Hub

Why: A hub only sends data to every device on the network (mark scheme line A), so no mark.

3Short recall1 markLANs & WANs Swap Remove

A school's computers are connected in a local area network (LAN). The internet connects computers across the world.

State the type of network that the internet is an example of.

[1 mark]
Mark scheme

  • WAN/Wide Area Network (1)

Allow wide area network, WAN network, and minor spelling errors where the meaning is clear, e.g. 'wide area netowrk'.

Do not accept LAN/local area network.

Do not accept a description such as 'covers a large area' without naming WAN.

Do not accept 'the internet' or 'world wide web'.

Example answers and how they were marked
Full marks1/1

WAN (wide area network)

Why: Correct type of network (1).

No marks0/1

A network that covers a large area.

Why: Describes a WAN but does not name the type; no mark.

No marks0/1

LAN (local area network)

Why: Names the wrong type of network; the internet is a WAN.
