Detailed Explanation with Core 2

Reference:

The default gateway directs network traffic to external networks. If the traffic is still going to the old firewall, updating the gateway setting will redirect it to the new firewall. This task is part of network configuration management covered in Core 2 (Core 2 Objective 2.5).

Detailed Explanation with Core 2

Reference:

If multiple unsuccessful attempts led to the account being locked, the technician should unlock the account. Core 2 covers user account management practices, including unlocking accounts and managing failed login attempts (Core 2 Objective 2.5).

Disabling guest accounts on domain-joined machines is done through Group Policy. Group Policy allows centralized management and configuration of operating systems, applications, and users' settings in an Active Directory environment. By using the Group Policy Editor (gpedit.msc), administrators can enforce policies such as disabling the guest account across all machines within the domain. The other options (Firewall, Microsoft Management Console, MSConfig) do not provide functionality specific to managing user accounts in this context.

User awareness education is the most effective method for reducing phishing attacks. Training users to recognize suspicious emails, links, and attachments can prevent them from falling for phishing attempts. Technical solutions like SMTP filtering (C) and restricting emails (D) can help but are not as effective without user vigilance. A BYOD policy (B) does not directly address phishing email threats.

XFS is a high-performance filesystem created by Silicon Graphics in 1994 and is commonly used by Linux operating systems. It supports large files and directories and is known for its robustness and scalability. Other filesystems like NTFS (Windows), APFS (macOS), and HFS (macOS) are used on different platforms.

The file type ISO is a disk image format that contains everything from a CD, DVD, or Blu-ray disc in a single file. When an ISO file is accessed, the system prompts the user to mount it as a virtual drive, which is why the technician received a 'mount a drive' prompt. MSI (A) is for installing software, ZIP (C) is a compressed file, and EXE (D) is an executable file.

In this case, abnormal behavior after opening a suspicious email suggests malware might have infected the device. A full factory reset is recommended to remove any persistent malware, especially when a restart does not resolve the issue. Deleting the email or reinstalling the browser will not remove the malware already on the device.

Disk encryption is the best method for securing a workstation used in financial transactions, such as point-of-sale systems. It ensures that if the workstation is stolen, all data on the disk is encrypted and cannot be accessed without proper credentials. File encryption (B) only encrypts individual files, and USB drive encryption (C) only applies to removable storage. Data-in-transit encryption (A) is not relevant for physical security.

Rootkits are particularly dangerous because they modify the operating system to hide their presence and can disable antivirus software like Windows Defender. Ransomware (A) encrypts files, but usually does not disable antivirus software. Spyware (C) and Keyloggers (D) typically do not directly disable antivirus programs either.
