We are troubleshooting a networking issue on a PC that is having trouble connecting to www.google.com (Links to an external site.). Name four commands that we would use as part of the troubleshooting process, include all necessary parameters and switches with each command.
Consider the following scenario: you have several TCP connections on your workstation that are in the state FIN WAIT 1. What is most likely taking place? Whose fault is it, exactly?
Your DHCP server’s scope is too small for the number of computers that are connecting to it each day. The majority of your users are wireless and come and go during the day. Due to change control restrictions, you can’t increase the size of your DHCP scope to add more addresses until the weekend. What else could you do to provide a temporary solution to this issue?

- The scenario includes one DHCP server in an Active Directory domain. The server is configured to provide IP addresses to DHCP clients on two different subnets. The subnets are separated by a router that has DHCP Forwarding enabled. In this scenario, you use ten of the excluded IP addresses to configure servers and other devices with static IP addresses and five additional IP addresses are left available for static configuration of new devices that you might want to add in the future. Write up the Powershell script for the following according to scenario IP configuration: Installing DHCP role (DHCP1) Creating DHCP security group (your Arid Number) in DHCP1 Note: Security Group should create with your arid number. Authorizing the DHCP1server in DC1 How to getClient4 adapter hardware information Disable and Enable a Network Adapter of Client4arrow_forwardOne of your work tasks is to inventory all the software running on the network. You’ve been running Wireshark on your network for several weeks now. You’ve built a long list of all the source and destination port numbers seen on your network. As you examine this list, you find that there are more than 100 port numbers that are not listed on the IANA port list. There are also about 20 port numbers that belong to applications you know are not running on your network. What happened? Why are your research results so far off base?arrow_forwardYou work as the IT administrator for a small corporate network. You need to configure the workstation in the Executive Office so it can connect to the local network and the internet. The workstation has two network interface cards. This will allow the workstation to connect to the local network (as shown in the Exhibits) and another small network, which is not yet built. In this lab, your task is to complete the following: Configure the IP version 4 TCP/IP settings for both network connections using the settings shown in the table below. Use the Network and Sharing Center in Windows to confirm that the workstation is properly connected to the small network and the Internet.

- Silicone Printers has raised a ticket claiming that it was unable to view websites from its workstations, because with every attempted access, the system displayed an error message that read "there is another device using the same IP address." What would you, as a network engineer, check for in such a scenario? Incorrect gateway Duplicate IP addresses Incorrect subnet mask DHCP scope exhaustionarrow_forwardYou could provide a static IP address to a host on your network when the service that host provides must always originate from the same server. In this case, the address would not change. I need to manually assign an IP address; which approach is the most effective way to do this? How did it get to be this way, and what factors contributed to it?arrow_forwardIn traditional physical networks, there was always some type of air gap [1] that existed or could be made by unplugging a cable between systems on a network. For example, you have two computers that are physically connected to the same network. If you unplug/disconnect the network cable or add a firewall between those two computers, they will not be able to communicate with each other. In a virtualized environment, the hypervisor always creates a software connection between systems, NOT a physical one. And since it is software based, there is no way to completely isolate one operating system from another. As a cybersecurity engineer, discuss the possible solutions to solve this problem in virtualized environments. Provide refrencesarrow_forward
