In CIDR notation, what does the value after the slash (for example, the /24 in 192.168.1.0/24) represent?
✓ Correct Answer: A
The slash value is the prefix length — the count of leading bits in the address that identify the network. A /24 means 24 bits identify the network and 8 bits remain for hosts. B describes a value derived from the host bits, not the prefix itself. C conflates prefix length with subnet count. D confuses CIDR notation with IP version.
Which dotted-decimal subnet mask is equivalent to the CIDR prefix /24?
✓ Correct Answer: B
A /24 prefix means 24 leading 1-bits in the mask: 11111111.11111111.11111111.00000000, which is 255.255.255.0. A is /8. C is /16. D is /29.
