You connect your laptop computer to a public, open Wi-Fi network and decide to check the connection. You open a command window on your laptop, run an “ipconfig” command, and find that the Wi-Fi DHCP service has assigned the following IP address and subnet mask to your computer: 10.52.81.183 255.255.252.0 (Hint: use a subnet worksheet from Week 5 as scratch paper to help you answer this. Note that this mask is subnetting in the third octet.) a. What is the...

Which of the following is the purpose of a subnet mask in a network? (Select all that apply) a. A subnet mask is not necessary when a default gateway is specified. b. A subnet mask is used to differentiate between the network address, the host addresses, and the broadcast address. c. A subnet mask is required only when bits are borrowed on a network. d. A subnet mask is used to determine in which subnet an IP address belongs. e....

Show work. 5. A host computer with an IP address of 10.10.20.5 using a subnet mask of 255.255.192.0 pings a computer with an IP address of 10.10.10.5. What happens to the data packet? a. The data packet is sent to the gateway. b. The data packet is sent to 10.10.20.192. c. The 10.10.10.5 is not in the same LAN; therefore, the data packet is sent out as a broadcast. d. The data packet is sent to the 127.0.0.1 network. e....
