Your Network Administrator has contacted you to assist in examining a workstation that has been showing network fluctuations time and again.
It seems that someone spilled some hot water over the Ethernet ports. Which of the following addresses will you choose to check the functionality of the Ethernet card without worrying about corrupted hardware and to ensure that the workstation's TCP/IP services are running?
ping -a 8.8.8.8
ping -a 0.0.0.0
ping 127.0.0.1
ping 192.168.1.1
Your corporation hosts a website at the static public IP address 92.110.30.123. A router directs this traffic to a web server at the private IP address 192.168.11.100. However, the web server needs a hardware upgrade and will be down for two days. Your network administrator has asked you to configure the router so that requests to the IP address 92.110.30.123 are redirected to the backup server for the website, which has the private IP address 192.168.11.110. The router’s inside Ethernet interface uses IP address 192.168.11.254 and its outside interface uses the IP address 92.110.30.65. Answer the following questions about the new static route you’ll be creating: 1. What is the router’s outside interface IP address? 2. What is the router’s inside interface IP address? 3. What is the website’s public IP address? 4. What is the private IP address of the backup web server?
I ran the ipconfig command on my computer and it reports an IP address 169.254.75.10 on the ethernet interface. Which device assigned this IP address to this interface?

- You as a network administrator want to protect the network from unauthorized traffic, and for this reason, you decide to change the native VLAN to an unused VLAN so that the untagged traffic is essentially directed toward a dead-end. Which of the following commands will you use to do this on a Cisco switch? a. set native-vlan-id b. set port-mode trunk c. switchport trunk native vlan d. ip dhcp snoopingarrow_forwardThe enterprise administrator has assigned you the network address 192.168.0.0/24 for the six branch office networks that you are setting up. Each branch office will have 10 computers in it. How can you subnet the 256 addresses to satisfy your needs (six subnets with at least 10 hosts n each one)? Hint: the subnet mask will need to be changed to create 6 smaller subnets from 192.168.0.0/24. If you don’t want to do binary math, you can use an online IP subnet calculator to figure this out. What IP addresses and subnet masks will the computers in the branch office network use? Note: Each subnet must have unique IP addresses in it and must be in the range of 192.168.0.0-255.
