1Multiple choice1 markPacket Switching Swap Remove

Data is broken into packets and sent across the internet.

Identify the device that forwards a packet towards its destination.

[1 mark]
  • AHub
  • BRouter
  • CServer
  • DSwitch
Mark scheme
  • B Router (1)
  • The only correct answer is B. The correct answer is Router.
  • A is not correct because a hub sends the data it receives to every device on the network
  • C is not correct because a server provides services, such as web pages, to client computers
  • D is not correct because a switch forwards data between the devices on one network
Example answers and how they were marked
Full marks1/1

B Router

Why: Selected the correct device: a router reads the destination IP address in each packet and forwards it towards its destination (1).

No marks0/1

D Switch

Why: A near miss: a switch forwards data between devices on one network, but it is a router that forwards packets between networks towards their destination, so no mark.

No marks0/1

A Hub

Why: Misconception from the examiners' reports: confusing LAN hardware with internet routing. A hub sends data to every device on the network and does not read IP addresses to forward packets, so no mark.

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

Routers forward data packets across the internet.

State the part of a data packet that a router uses to decide where to send it.

[1 mark]
Mark scheme

Award one mark for:

  • (Destination) IP address (1)

Allow IP address on its own (the destination is implied).

Do not accept source IP address/IP address of the sender.

Do not accept MAC address.

Do not accept domain name/web address.

Example answers and how they were marked
Full marks1/1

The destination IP address.

Why: Names the destination IP address (1).

No marks0/1

The domain name.

Why: A domain name is not used by a router to route a packet; it must be translated to an IP address first, so no mark.

No marks0/1

The MAC address.

Why: A MAC address is not used to route packets across the internet; the Do not accept line applies.
