Explanation: GPT is the correct answer for this question. GPT stands for GUID Partition Table, and it is a partition style that supports up to 128 primary partitions and up to 18 exabytes of disk size per partition. GPT also uses a unique identifier for each partition and provides better data protection and recovery. GPT is suitable for partitioning a hard disk that has five primary partitions with 4TB of free space each. EFS, MBR, and FAT32 are not correct answers for this question. EFS stands for Encrypting File System, and it is a feature that allows encrypting files and folders on NTFS volumes. EFS is not a partition style, but rather a file system attribute. MBR stands for Master Boot Record, and it is an older partition style that supports up to four primary partitions and up to 2TB of disk size per partition. MBR cannot handle five primary partitions with 4TB of free space each. FAT32 stands for File Allocation Table 32, and it is a file system that supports up to 32GB of disk size per partition and up to 4GB of file size. FAT32 is not a partition style, but rather a file system type.

Explanation: A VPN (Virtual Private Network) is a service that allows remote employees to access the company’s network resources securely over the internet as if they were on premises. A VPN encrypts the data traffic between the employee’s device and the VPN server, and assigns the employee a virtual IP address that belongs to the company’s network. This way, the employee can access the local servers, files, printers, and other resources without exposing them to the public internet. A VPN also protects the employee’s privacy and identity by masking their real IP address and location.

Explanation:
The technician should provide the user with a unique ticket number that can be referenced on subsequent calls to make sure the ticket is associated with the correct user. This is because registering the ticket with a unique user identifier, having the user provide a callback phone number to be added to the ticket, or assigning the ticket to the department’s power user will not ensure that the ticket is associated with the correct user2.

Explanation: The systems administrator should clear the application cache12. If clearing the application cache does not work, the systems administrator should uninstall and reinstall the application12. Resetting the phone to factory settings is not necessary at this point12. Installing an alternative application with similar functionality is not necessary at this point12.

Explanation:
This is because WPA2 with AES is the most secure wireless network configuration that is available on a ten-year-old SOHO wireless router.

Explanation:
The technician should guide the user to update Windows through the built-in "Check for Updates" feature. This can be done by having the user click in the Search field, type "Check for Updates", and then press the Enter key. This will bring up the Windows Update function, which will search for any available updates and give the user the option to install them.

Explanation: Developer Mode on Windows 10 is a feature that allows developers to test and debug their applications on their devices, as well as sideload apps and access other developer tools12. To enable Developer Mode, the user needs to go to the Settings app, select Update & Security, choose For Developers, and switch to Developer Mode123. However, enabling Developer Mode requires internet connectivity, as Windows will download and install a package of features, such as Windows Device Portal and SSH services, that are necessary for Developer Mode124. If the user does not have internet connectivity, they will receive a “failed to install package” message when trying to enable Developer Mode4. Therefore, the first thing that the technician should do is to ensure that the laptop has internet access, either through Wi-Fi or Ethernet, and then try to enable Developer Mode again4

Explanation:
Multifactor authentication will be forced for Wi-Fi after deploying a client certificate to be used for Wi-Fi access for all devices in an organization3.
