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).

2Multiple choice1 markAddressing Swap Remove

Every device that connects to the internet is given an IP address.

Identify the number of bits in an IPv4 address.

[1 mark]
  • A4
  • B8
  • C32
  • D128
Mark scheme
  • C 32 (1)
  • The only correct answer is C. The correct answer is 32.
  • A is not correct because 4 is the number of groups of numbers in an IPv4 address
  • B is not correct because 8 is the number of bits in each group of an IPv4 address
  • D is not correct because 128 is the number of bits in an IPv6 address
Example answers and how they were marked
Full marks1/1

C 32

Why: Correct option (1): an IPv4 address is 32 bits long.

No marks0/1

B 8

Why: 8 is the number of bits in one group of an IPv4 address, not the whole address (mark scheme line B), so no mark.

No marks0/1

D 128

Why: 128 is the length of an IPv6 address, not an IPv4 address (mark scheme line D), so no mark.

3Short recall2 marksWired Connections Swap Remove

A company can choose between two wired connections. Connection B has a higher bandwidth than connection A.

Give two benefits to the company of choosing connection B.

[2 marks]
Mark scheme

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

  • Files/data download/upload more quickly (1)
  • More employees can use the connection at the same time without it slowing down (1)
  • Web pages/streamed video load more quickly with less buffering (1)
  • Video calls/conferencing run at a higher quality (1)
  • Updates/backups can be completed in less time (1)

Allow 'multiple users' or 'more devices' for the shared-use point

Allow 'video streams more quickly' or 'less buffering' on their own

Do not accept lower latency, as a higher bandwidth does not reduce latency

Do not accept 'more data can be transferred per second' or 'a bigger bandwidth', as these repeat what bandwidth is

Do not accept 'more reliable' on its own, as a higher bandwidth does not make a wired connection more reliable

Example answers and how they were marked
Full marks2/2

Files will download more quickly, and more employees can use the internet at the same time without the connection slowing down.

Why: Files download more quickly (1) and more users without slowdown (1).

Some marks1/2

Web pages will load faster and the connection will have a longer range.

Why: Web pages load faster (1); the range of a connection is not increased by bandwidth, so that point is not credited.

No marks0/2

The connection will be more reliable because it has a bigger bandwidth.

Why: 'More reliable' is not credited on its own and 'bigger bandwidth' repeats the question, so no marks.
