WPA2 is the only protocol among the options that supports fast roaming between networks. Fast roaming, also known as IEEE 802.11r or Fast BSS Transition (FT), enables a client device to roam quickly in environments implementing WPA2 Enterprise security, by ensuring that the client device does not need to re-authenticate to the RADIUS server every time it roams from one access point to another1. WEP, WPA, LEAP, and PEAP do not support fast roaming and require the client device to perform the full authentication process every time it roams, which can cause delays and interruptions in the network service.

Explanation
The Network and Sharing Center is a Control Panel utility that allows users to view and modify network settings, such as IP address, subnet mask, default gateway, DNS servers, and network profiles. To change the IP and gateway settings of a Windows workstation, the technician can follow these steps:
Open the Network and Sharing Center by clicking on the network icon in the system tray or by searching for it in the Start menu.
Click on Change adapter settings on the left sidebar.
Right-click on the network adapter that is connected to the network and select Properties.
Double-click on Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) depending on the network protocol used.
Select Use the following IP address and enter the desired IP address, subnet mask, and default gateway for the workstation. Alternatively, select Obtain an IP address automatically if the network uses DHCP to assign IP addresses dynamically.
Click OK to save the changes and close the dialog boxes.

Explanation
A technician setting up a new laptop must ensure that users cannot install virtual machines as the company's security policy states One way to prevent users from enabling virtual technology is by implementing Secure Boot. Secure Boot is a feature of UEFI firmware that ensures the system only boots using firmware that is trusted by the manufacturer. It verifies the signature of all bootloaders, operating systems, and drivers before running them, preventing any unauthorized modifications to the boot process. This will help prevent users from installing virtual machines on the laptop without authorization.

Detailed Explanation with Core 2 References:Intrusion Detection Systems (IDS) monitor network traffic for malicious activities and alert administrators, helping to prevent malware infections before they can impact the network significantly. CompTIA Core 2 emphasizes the importance of implementing preventive measures like IDS to proactively detect and respond to potential threats (Core 2 Objective 2.3).
