1Multiple choice1 markAddressing Swap Remove

A technician is checking the IP addresses of the devices on a network.

Identify the valid IPv4 address.

[1 mark]
  • A192.168.1
  • B192.168.1.1
  • C192.168.1.1.1
  • D192.168.1.256
Mark scheme
  • B 192.168.1.1 (1)
  • The only correct answer is B. The correct answer is 192.168.1.1.
  • A is not correct because it is an incomplete address with only three numbers, not four
  • C is not correct because it is an address with five numbers, not four
  • D is not correct because it contains 256, which is outside the range 0 to 255
Example answers and how they were marked
Full marks1/1

B 192.168.1.1

Why: Correct option (1): an IPv4 address is four numbers, each from 0 to 255, separated by dots.

No marks0/1

D 192.168.1.256

Why: Near miss: it has four numbers but 256 is outside the range 0 to 255 (mark scheme line D), so no mark.

No marks0/1

A 192.168.1

Why: It has only three numbers, so it is not a complete IPv4 address (mark scheme line A), so no mark.

2Short 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.

3Short recall2 marksAddressing Swap Remove

The internet is a global network of networks.

Define the term IP address.

[2 marks]
Mark scheme

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

  • A unique identifier/number (1)
  • Given to a device on a network/the internet (1)
  • Used to send/receive/route data (to the correct destination) (1)

Allow computer/laptop/phone/printer etc. for device.

Do not accept a website address/domain name.

Do not accept MAC address (this is a hardware identifier set by the manufacturer, not an address given to a device for use on a network).

Do not accept 'an address'/'a location' on its own, without saying that it identifies a device on a network/the internet.

Example answers and how they were marked
Full marks2/2

A unique number given to a device on the internet so that data can be sent to it.

Why: Unique identifier (1) and given to a device on the internet (1); the third creditworthy point is not needed for full marks.

Some marks1/2

A unique number.

Why: Gives a unique identifier (1) but does not say what it is given to or what it is used for.

No marks0/2

The address of a website, such as google.co.uk.

Why: Describes a domain name/website address, not an IP address; the Do not accept line applies.
