@comptiapassemall: CCNA SUBNETTING: Master the 255.255.255.240 Trick! That tricky CCNA IPv4 subnetting question with 255.255.255.240? Don't let it fool you! Here's the simple breakdown to confidently answer it every time: * Understand the 240: First, convert the final '240' in the subnet mask into its binary form, which is 11110000. * Count Borrowed Bits: Next, count the number of 'ones' you have borrowed for subnetting. In this case, you see four 'ones' (N=4). * Apply the Formula: To find the number of subnets, use the simple formula 'two to the power of N' (2^N). So, we calculate 2^4. * The Answer: Two times two is four, times two is eight, times two is sixteen. You can create 16 subnets!
