Chapter 1: Domain 1.0 Network Architecture
- A, C. A multilayer switch operates at Layer 2 and Layer 3 of the OSI model.
- C. An IPv4 address is a 32-bit address. It is composed of four sections of 8 bits each, called octets. Each octet is converted to decimal for configuration purposes, but the computer uses the entire 32-bit address for communication.
- B. If you have a Class B address with a default subnet mask, then the current subnet mask is 255.255.0.0. This means you have 16 bits for networks and 16 bits for hosts. If you want to create eight subnets, then you need to solve for 2s > 8. Solving for s, you can determine that you need to use the first 3 bits from the network address to create the subnets. The ...
