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

A packet of data is sent across the internet to a web server. The packet has a header that stores information about the packet.

Identify the information in the packet header that a router uses to forward the packet towards its destination.

[1 mark]
  • AThe destination domain name
  • BThe destination IP address
  • CThe MAC address of the sender
  • DThe name of the file being sent
Mark scheme
  • B The destination IP address (1)
  • The only correct answer is B. The correct answer is the destination IP address.
  • A is not correct because a domain name is converted to an IP address by a DNS server before routing begins
  • C is not correct because the sender's MAC address is only used to deliver the packet on the local network
  • D is not correct because the file name is not used to route packets
Example answers and how they were marked
Full marks1/1

B The destination IP address

Why: Correct option (1): a router reads the destination IP address in the header to forward the packet towards its destination.

No marks0/1

A The destination domain name

Why: A domain name is converted to an IP address by a DNS server before routing begins, so it is not the routing information in the header (mark scheme line A); no mark.

No marks0/1

C The MAC address of the sender

Why: The sender's MAC address is only used to deliver the packet on the local network, so it is not used by the router to forward the packet (mark scheme line C); no mark.

3Short recall1 markAddressing Swap Remove

An IPv4 address is made up of four 8-bit numbers separated by dots.

State the range of values that each number in an IPv4 address can have.

[1 mark]
Mark scheme

Award one mark for:

  • 0 to 255 (1)

Allow 0–255 / 0-255 / between 0 and 255 / 0 and 255.

Do not accept 1 to 255 (0 is a valid value).

Do not accept any range that includes 256, e.g. 0 to 256.

Example answers and how they were marked
Full marks1/1

0 to 255

Why: Gives the correct range (1).

No marks0/1

1 to 255

Why: Near miss: excludes 0, which is a valid value; the Do not accept line applies.

No marks0/1

0 to 256

Why: Includes 256, which is not valid; the Do not accept line applies.
