| Binary ANDing | the process of multiplying two binary numbers |
| What items are needed to calculate the network address? | IPv4 address and subnet mask |
| What is identified by a device's network address? | The network segment the device belongs to |
| The network address is located where in the network segment? | First |
| gateway IP address, also referred to as a default gateway address | a local network device's address that transmits local network packets to outside networks. |
| To which IP address does a device send a packet when the packet's destination address is on a different network? | Gateway address |
| The gateway IP address is assigned to which physical device? | Router |
| Routers connect which type of networks together? | Networks with different network addresses |
| Classless addressing, or Classless Inter-Domain Routing (CIDR), | an addressing scheme using variable length subnet mask (VLSM) |
| Variable length subnet mask, or VLSM | a subnet design using multiple masks in the same network |
| What is the primary advantage of using VLSM in a network? | Allows for more efficient use of IP addresses |
| Which of the following best describes the process of VLSM? | Assigning different subnet masks to different subnets based on their size |
| In a network using VLSM, which of the following is a key consideration when designing the subnets? | Ensuring that subnets do not overlap |
| Subnetting | the process of dividing a network into smaller networks (subnets), by borrowing bits from the IP address host segment to the network segment |
| What is a broadcast address? | The last host IP address in the range defined by the subnet |
| What is a network ID? | The first host IP address available in a subnet |
| What is a host address? | Any address in the host network address range, except for the host address range's first and last addresses. |
| What is the broadcast address for the network 192.168.1.12/24? | 192.168.1.255 |
| What is the network ID for the network 172.16.0.2/16? | 172.16.0.0 |
| For the network 192.168.0.1/24, identify a network host address. | 192.168.0.1 |
| What is the minimum amount of bits needed to be borrowed from the host segment to create four subnets? 2^? | 2 |
| What is the minimum amount of bits needed to be borrowed from the host segment to create six subnets? 2^? | 3 |
| What is the minimum amount of bits needed to be borrow from the hosts to create 11 subnets? 2^? | 4 |
