1Multiple choice1 markProtocols & Layers Swap Remove

A user reads email on a laptop. The emails are downloaded to the laptop and removed from the mail server.

Identify the email protocol being used.

[1 mark]
  • AFTP
  • BIMAP
  • CPOP3
  • DSMTP
Mark scheme
  • C POP3 (1)
  • The only correct answer is C. The correct answer is POP3.
  • A is not correct because FTP is used to transfer files.
  • B is not correct because IMAP keeps emails on the server.
  • D is not correct because SMTP is used to send outgoing email between mail servers.
Example answers and how they were marked
Full marks1/1

C POP3

Why: POP3 downloads emails and removes them from the server (1).

No marks0/1

B IMAP

Why: IMAP keeps emails on the server, so it does not match the scenario where emails are removed from the server (0).

No marks0/1

D SMTP

Why: SMTP is used to send outgoing email, not to retrieve email (0).

2Short recall2 marksWired Connections Swap Remove

A school connects its desktop computers to the network using cables.

Give two reasons why the wired connections give better network performance than the wireless connections.

[2 marks]
Mark scheme

Award one mark for any of the following up to a maximum of two marks:

  • Faster transmission speed (1)
  • Higher bandwidth (1)
  • Lower latency (1)
  • Not affected by interference (from other devices/walls) (1)
  • No blind spots/not affected by distance from the wireless access point (1)

Do not accept benefits of wireless connections, e.g. users can move around the building with their devices

Do not accept 'easier to set up' or 'does not need a password' as these are not about network performance

Example answers and how they were marked
Full marks2/2

The wired connection is not affected by interference from other devices, and it has a lower latency than Wi-Fi.

Why: Interference point (1) and lower latency point (1).

Some marks1/2

It has a faster transmission speed and the users can move around the building with their computers.

Why: Faster transmission speed (1); moving around is a benefit of wireless, so is not credited.

No marks0/2

It is easier to set up the network and the users do not need a password.

Why: Neither point is about network performance; the mark scheme does not accept 'easier to set up' or password points, so no marks.

3Explain2 marksAddressing Swap Remove

A laptop is used at home and is then taken on holiday, where it connects to a different network.

Explain why the laptop is given a different IP address when it is used on holiday.

[2 marks]
Mark scheme

Award up to two marks for a linked explanation such as:

  • The laptop is connecting to a different network (1) so it needs an address that belongs to/is unique on that network (1)
  • The router/ISP on the new network assigns the address (1) because addresses are given out by the network the device is connected to (1)
  • The home IP address is only valid on the home network (1) so it cannot be used to send data on another network (1)

For both marks, the expansion must follow/associate with the statement.

Do not accept 'it has a dynamic IP address' on its own, as this repeats the question.

Do not accept answers that say the IP address is stored in the device's hardware/network card, as this describes the MAC address.

Example answers and how they were marked
Full marks2/2

It is connecting to a different network now, so the router there gives it an address that works on that network.

Why: Point that the laptop is on a different network (1) and linked reason that the new router assigns an address valid/unique on that network (1).

Some marks1/2

Because it is connecting to a different network.

Why: A valid point (1) but no linked reason about where the new address comes from or why the old one cannot be used.

No marks0/2

Because the IP address is built into the laptop's network card and it changes when it is plugged into a new network.

Why: Misconception: an address fixed in the hardware is the MAC address; the mark scheme says not to accept this, so no marks.
