Identify the network ID section of the following IP address and subnet mask: 10.14.12.43–255.255.255.0.
- 14
- 14.12
- 12.43
10.14.12

11111111111111111111111100000000
A subnet is all ones followed by zeroes
What does ARP stand for?
Address Reconciliation Process
Automated Ranking Protocol
Address Resolution Protocol
Address Resolution Protocol
ARP is the Address Resolution Protocol, which is how a TCP/IP network figures out the MAC address based on the destination IP address

10000111
10001010
10001010 is the number 138 in binary
When DHCP Discover fails, what process will the client use to generate an address for itself?
ATAPI (Automatic Temporary Address Program Initiator)
APIPA (Automatic Private IP Addressing)
ATIPA (Automatic Temporary IP Address)
APIPA (Automatic Private IP Addressing)
A client uses APIPA (Automatic Private IP Addressing) to generate an address when DHCP Discover fails
Which of the following is a valid loopback address?
- 0.0.1
- 0.0.0
- 24.0.1
- 24.0.1
127. 24.0.1. Any address in the 127.0.0.0/8 subnet will work as a loopback
