70-293 test RRS feed

  • Question

  • I'm in the process of reading the MOAC textbook for 70-293, and I have a major concern that I hope can be clarified.

    In chapter 2, when it talks about subnetting, (most likely due to the date the book was published,) it is assuming the fact that subnet-0 and all-ones subnet are not usable. For example, the book says that the usable address space for is to This is saying that the subnet-0 and subnet-224 is unusable.

    When I do the certification, do I have to assume this outdated standard, or can I assume that these excluded subnets are usable, as they certainly are today?
