Question Image

Refer to the exhibit. An IP subnet must be configured on each router that supplies enough addresses for the assigned hosts and allows for no more than 10% growth in new hosts. Which configuration script must be used?

  • A
  • B
  • C
  • D
Explanation

Allowing 10% growth requires subnets supporting at least 1,016, 248, and 4,006 hosts. The smallest suitable IPv4 subnets are /22 (1,022 usable addresses), /24 (254 usable addresses), and /20 (4,094 usable addresses), respectively. These correspond to masks 255.255.252.0, 255.255.255.0, and 255.255.240.0.
