1Multiple choice1 markThe Internet Swap Remove

An IPv4 address is written as four groups of numbers.

Identify the valid IPv4 address.

[1 mark]
  • A192.168.0
  • B192.168.0.1
  • C192.168.0.1.2
  • D192.168.0.1.256
Mark scheme
  • B 192.168.0.1 (1)
  • The only correct answer is B. The correct answer is 192.168.0.1.
  • A is not correct because it has only three groups of numbers; an IPv4 address has four groups separated by dots
  • C is not correct because it has five groups of numbers; an IPv4 address has four groups separated by dots
  • D is not correct because 256 is outside the valid range for a group, which is 0 to 255
Example answers and how they were marked
Full marks1/1

B 192.168.0.1

Why: Correct option: four groups of numbers, each from 0 to 255, separated by dots (1).

No marks0/1

A 192.168.0

Why: Near miss: only three groups of numbers are shown, so it is not a valid IPv4 address; A is not credited.

No marks0/1

D 192.168.0.1.256

Why: Shows the misconception that a group can be 256; the rule is each group must be 0 to 255, so D is not credited.

2Multiple choice1 markAddressing Swap Remove

Data is sent across the internet in packets.

Identify the device that uses IP addresses to forward packets from one network to another.

[1 mark]
  • AHub
  • BNetwork interface card
  • CRouter
  • DSwitch
Mark scheme
  • C Router (1)
  • The only correct answer is C. The correct answer is router.
  • A is not correct because a hub sends data to every device on the network
  • B is not correct because a network interface card connects a device to a network
  • D is not correct because a switch forwards data within a single network using MAC addresses
Example answers and how they were marked
Full marks1/1

C Router

Why: Correct option (1): a router uses IP addresses to forward packets between networks.

No marks0/1

D Switch

Why: A switch forwards data within one network using MAC addresses, not between networks (mark scheme line D), so no mark.

No marks0/1

A Hub

Why: A hub only sends data to every device on the network (mark scheme line A), so no mark.

3Short recall1 markAddressing Swap Remove

Devices are given IP addresses.

Define the term dynamic IP address.

[1 mark]
Mark scheme

Award one mark for:

  • (An IP address that) can change / is not permanent (1)

Allow a temporary IP address.

Allow it is assigned each time the device connects to the internet.

Do not accept an IP address that is assigned (automatically) by a router/DHCP without any idea that it can change.

Do not accept static IP address / fixed IP address / an IP address that never changes (this is a static IP address).

Example answers and how they were marked
Full marks1/1

An IP address that can change each time the device connects to the internet.

Why: States that the IP address can change (1).

No marks0/1

An IP address that is assigned automatically by a router.

Why: Describes assignment only; the mark scheme does not accept assignment without the idea that the address can change.

No marks0/1

An IP address that never changes.

Why: Confuses dynamic with static; the Do not accept line applies.
