Detailed explanation-1: -Several key differences between MAC and IP addresses exist. First, MAC addresses never change and are only used in the local network, while IPs identify network devices globally and can change depending on your location.
Detailed explanation-2: -A static IP address is an address that is permanently assigned to a device on a network. This address is independent of the device’s physical location and is used when connecting to the network. The address is usually assigned to a device and never changes unless changed manually.
Detailed explanation-3: -The correct answer is 00-11-20-M1-BC-B0, because the MAC address consists of 6 groups of Hexadecimal characters and the letter M in the 3rd group is the only character that is not a Hexadecimal character.
Detailed explanation-4: -MAC address changes apply to the traffic entering a virtual machine from the virtual switch. If MAC address changes are set to Accept, then it means that you allow the virtual machine to receive traffic originally intended for another VM, by impersonating the other VM’s MAC address.
Detailed explanation-5: -The MAC address of a WiFi device is hard-coded at the hardware level, so it can’t really be changed (imagine that it’s the serial number of your network adapter). But, that doesn’t mean that it’s not possible to trick the OS into believing that the MAC address is different, hiding the true, hard-coded MAC address.
