Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • IP address ranges (e.g., 10.1.1.1-10.1.1.50)

    Why this is correct

    IP ranges are supported in address books.

  • Routing protocol metric values

    Why it's wrong here

    Routing metrics belong to routing configuration, not address books.

  • Interface speed descriptors

    Why it's wrong here

    Interface speeds are hardware/physical attributes.

  • IP subnet prefix notation (e.g., 192.168.1.0/24)

    Why this is correct

    Prefix notation is standard for address book entries.

  • Mac address binding tables

    Why it's wrong here

    MAC addresses are not configured in address books for security policies.

Visual reference

192.168.1.0 /24 256 addresses (254 usable) 192.168.1.0 /25 Subnet A 128 addr (126 usable) 192.168.1.128 /25 Subnet B 128 addr (126 usable) Borrowing 1 bit from host portion creates 2 subnets (/25)
