1Multiple choice1 markProtocols & Layers Swap Remove

[1 mark]
  • AFTP
  • BHTTP
  • CSMTP
  • DTCP
Mark scheme
  • C SMTP (1)
  • The only correct answer is C. The correct answer is SMTP.
  • A is not correct because FTP is used to upload and download files
  • B is not correct because HTTP is used to request web pages
  • D is not correct because TCP is a transport-layer protocol that splits data into packets and reassembles them
Example answers and how they were marked
Full marks1/1

C SMTP

Why: Selected the correct email sending protocol (1).

No marks0/1

A FTP

Why: FTP is a file transfer protocol, not an email sending protocol, so no mark is awarded (0).

No marks0/1

B HTTP

Why: HTTP is used for requesting web pages, not for sending email, so no mark is awarded (0).

2Multiple choice1 markLANs & WANs Swap Remove

A hospital has computers, printers and servers in one building.

Identify the type of network that connects these devices.

[1 mark]
  • ALAN
  • BPAN
  • CVPN
  • DWAN
Mark scheme
  • A LAN (1)
  • The only correct answer is A. The correct answer is LAN (Local Area Network).
  • B is not correct because a PAN connects devices around one person over a short range
  • C is not correct because a VPN is a secure private connection made over a public network, not a network covering one building
  • D is not correct because a WAN connects networks over a large geographical area
Example answers and how they were marked
Full marks1/1

A LAN

Why: Correct option: a LAN connects devices on one site, such as one building (1).

No marks0/1

D WAN

Why: Near miss: a WAN connects networks over a large geographical area, not devices within one building (0).

No marks0/1

C VPN

Why: Misconception: a VPN is a secure connection over a public network, not the type of network for devices in one building (0).

3Explain2 marksProtocols & Layers Swap Remove

A bank's website can use HTTP or HTTPS.

Explain one benefit to a customer of the bank's website using HTTPS.

[2 marks]
Mark scheme

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

  • Data is encrypted/scrambled (1) so it cannot be read/understood if it is intercepted (1)
  • The customer's bank/personal details are kept secure/private (1) because the data is encrypted/scrambled during transmission (1)
  • The customer's login details/password cannot be read by an eavesdropper (1) because HTTPS encrypts/scrambles the data sent to and from the web server (1)

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

Allow 'scrambled' as an alternative to 'encrypted'.

Do not accept 'it is more secure/safe' or 'the data is secure' on its own, without saying how it is made secure (e.g. encryption/scrambling).

Do not accept faster loading/speed, or claims that HTTPS stops viruses or always proves the website is genuine.

Example answers and how they were marked
Full marks2/2

The data is encrypted so anyone intercepting it cannot read the customer's bank details.

Why: Linked point (1) and reason (1): encryption means intercepted data cannot be read.

Some marks1/2

The data is encrypted so the website is secure.

Why: Point (1) for encryption, but 'secure' on its own is a near-miss that the mark scheme does not credit as the linked reason; it must say why, e.g. that intercepted data cannot be read.

No marks0/2

HTTPS is faster than HTTP so the customer can log in more quickly.

Why: Speed is not a benefit of HTTPS and is named in a 'Do not accept' line, so no creditworthy point is given.
