Hello, When you are asked for the number of subnets in the exam CCNA 640-607:
ie. 150.10.10.10 255.255.255.252.0 -> subnet bits = 6 -> supported subnets: 2^6 or 2^6-2 ?? In other words: if noting is mentioned in the question, do I have to count zero-subnet and broadcast subnet as valid ? or invalid ? when nothing is mentioned.....
