The ipconfig command is a utility that allows you to view and modify the network configuration of a Windows computer. By running the command "ipconfig /all", you can view detailed information about the network configuration of your computer, including the IP address, subnet mask, default gateway, and DNS server addresses.
Option A (netstat -a) is a command that displays active network connections and their status, but it does not display IP address or other network configuration information. Option B (ifconfig) is a command used on Linux and Unix systems to view and modify network configuration, but it is not available on Windows. Option C (ip addr) is a command used on Linux and Unix systems to view and modify network configuration, but it is not available on Windows.

DHCP exhaustion is a situation where the DHCP server runs out of available IP addresses to assign to clients. This can happen due to misconfiguration, malicious attacks, or high demand. When a client requests an IP address from the DHCP server and does not receive a response, it may resort to using an APIPA address, which is a self-assigned address in the range of 169.254.0.1 to 169.254.255.254. APIPA addresses are only valid for local communication and cannot access the internet or other networks. Therefore, a workstation showing an APIPA address indicates that it failed to obtain a valid IP address from the DHCP server, most likely due to DHCP exhaustion

A wireless survey is the first step that a network administrator should do before adding access points to the network. A wireless survey is a process of collecting data about the wireless environment, such as signal strength, channel usage, interference, and coverage. A wireless survey can help the network administrator to determine the optimal locations and configurations for the access points to provide the best possible coverage and performance for the wireless network. A wireless survey can also help to identify and troubleshoot any issues that may cause improper coverage in some areas. https://www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/116057-site-survey-guidelines-wlan-00.html

To monitor and provide traffic segmentation across the network, a technician may use the concept of VLANs (Virtual Local Area Networks). VLANs are a way of dividing a single physical network into multiple logical networks, each with its own unique identifier or "tag." By assigning each department a specific VLAN identifier, the technician can segment the network traffic and ensure that the different departments' traffic is kept separate from one another. This can help to improve network security, performance, and scalability, as well as allowing for better monitoring and control of the network traffic.
To implement VLANs, the technician will need to configure VLAN tagging on the network devices, such as switches and routers, and assign each department's devices to the appropriate VLAN. The technician may also need to configure VLAN trunking to allow the different VLANs to communicate with each other.
By using VLANs, the technician can effectively monitor and segment the network traffic, providing better control and visibility into the network.

A false camera is a dummy device that looks like a real camera but does not actually record or transmit any video. It is used to deter potential intruders or attackers from entering or damaging a building by creating the illusion of surveillance. Therefore, it is a preventive measure that aims to reduce the likelihood or impact of a security breach. It is not a detection, recovery, or identification tool, as it does not alert, restore, or recognize any security incidents.
