A technician requires graphical remote access to various Windows, Linux, and macOS desktops on the company LAN. The security administrator asks the technician to utilize a single software solution that does not require an external internet connection. Which of the following remote access tools is the technician most likely to install?
Correct Answer: A
VNC (Virtual Network Computing) is a remote access tool that allows the technician to access and control various Windows, Linux, and macOS desktops on the company LAN using a graphical user interface. VNC does not require an external internet connection, as it works over a local network or a VPN. VNC uses a client-server model, where the server runs on the remote desktop and the client connects to it from another device. VNC can transmit the keyboard and mouse events from the client to the server, and the screen updates from the server to the client, enabling the technician to interact with the remote desktop as if it were local12. VNC is a better option than the other choices because: * RMM (Remote Monitoring and Management) (B) is not a single software solution, but a category of software solutions that enable IT professionals to remotely monitor, manage, and troubleshoot multiple devices and networks. RMM software may include remote access tools, but also other features such as patch management, backup and recovery, security, reporting, and automation. RMM software may require an external internet connection, as it often relies on cloud-based services or web-based consoles34. * RDP (Remote Desktop Protocol) is a remote access tool that allows the technician to access and control Windows desktops on the company LAN using a graphical user interface. However, RDP is not compatible with Linux or macOS desktops, unless they have third-party software installed that can emulate or translate the RDP protocol. RDP also has some security and performance issues, such as encryption vulnerabilities, bandwidth consumption, and latency problems56. * SSH (Secure Shell) (D) is a remote access tool that allows the technician to access and control various Windows, Linux, and macOS desktops on the company LAN using a command-line interface. SSH does not require an external internet connection, as it works over a local network or a VPN. SSH uses encryption and authentication to secure the communication between the client and the server. However, SSH does not provide a graphical user interface, which may limit the functionality and usability of the remote desktop7 .

Question 212
Antivirus software indicates that a workstation is infected with ransomware that cannot be quarantined. Which of the following should be performed first to prevent further damage to the host and other systems?
Correct Answer: A
Turning off the machine is the first and most urgent step to prevent further damage to the host and other systems. Ransomware can encrypt files, steal data, and spread to other devices on the network if the infected machine remains online. Turning off the machine will stop the ransomware process and isolate the machine from the network12. The other options are either ineffective or risky. Running a full antivirus scan may not detect or remove the ransomware, especially if it is a new or unknown variant. Removing the LAN card may disconnect the machine from the network, but it will not stop the ransomware from encrypting or deleting files on the local drive. Installing a different endpoint solution may not be possible or helpful if the ransomware has already compromised the system or blocked the installation.
Question 213
A systems administrator is creating periodic backups of a folder on a Microsoft Windows machine. The source data is very dynamic, and files are either added or deleted regularly. Which of the following utilities can be used to 'mirror the source data for the backup?
Correct Answer: C
Robocopy is a command-line utility that can be used to mirror the source data for the backup. It can copy files and folders with various options, such as copying only changed files, preserving attributes and permissions, and retrying failed copies. Robocopy is more powerful and flexible than copy or xcopy, which are simpler commands that can only copy files and folders without mirroring or other advanced features. Copy-Item is a PowerShell cmdlet that can also copy files and folders, but it is not a native Windows utility and it requires PowerShell to run1.

Question 215
A systems administrator is creating a new document with a list of the websites that users are allowed to access. Which of the following types of documents is the administrator MOST likely creating?
Correct Answer: A
Explanation An access control list (ACL) is a list of permissions associated with a system resource (object), such as a website. An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects1. A systems administrator can create an ACL to define the list of websites that users are allowed to access.
