1Multiple choice1 markThe Internet Swap Remove

Identify the number of bits in an IPv4 address.

[1 mark]
  • A8
  • B32
  • C128
  • D256
Mark scheme
  • B 32 (1)
  • The only correct answer is B. The correct answer is 32.
  • A is not correct because 8 is the number of bits in one part of an IPv4 address, not the whole address
  • C is not correct because 128 bits is the length of an IPv6 address
  • D is not correct because 256 is the number of possible values in one 8-bit part of an IPv4 address
Example answers and how they were marked
Full marks1/1

B 32

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

No marks0/1

A 8

Why: Near miss: 8 is the number of bits in one part of an IPv4 address, not the whole address, so A is not credited.

No marks0/1

C 128

Why: Shows confusion between IPv4 and IPv6; 128 bits is the length of an IPv6 address, so C is not credited.

2Multiple choice1 markWireless Connections Swap Remove

A wireless network can use the 2.4 GHz or 5 GHz frequency band.

Identify the advantage of using the 5 GHz band instead of the 2.4 GHz band.

[1 mark]
  • AGreater range
  • BHigher data transfer speed
  • CMore able to pass through walls
  • DUses less bandwidth
Mark scheme
  • B Higher data transfer speed (1)
  • The only correct answer is B. The correct answer is higher data transfer speed.
  • A is not correct because the 2.4 GHz band has the greater range
  • C is not correct because the 2.4 GHz band passes through walls more easily
  • D is not correct because the 5 GHz band does not use less bandwidth
Example answers and how they were marked
Full marks1/1

B Higher data transfer speed

Why: Correct advantage: 5 GHz gives higher data transfer rates (1).

No marks0/1

A Greater range

Why: Greater range is a feature of the 2.4 GHz band, not an advantage of 5 GHz; no mark.

No marks0/1

C More able to pass through walls

Why: 5 GHz signals are less able to pass through walls than 2.4 GHz signals; no mark.
