CompTIA Updated 220-1202 Exam Questions and Answers by rayna

The technician should not disclose information about other customers’ issues, environments, or outcomes because that violates professional confidentiality expectations. Instead, the best response is to explain the general troubleshooting process the technician will follow—such as gathering symptoms, checking logs/connection status, isolating whether the problem is local vs. ISP, testing known-good hardware, and documenting results—without referencing other clients’ specific cases. Quentin Docter emphasizes that as a computer professional you must uphold confidentiality and ensure sensitive information “goes no further,” reinforcing that you should not reveal work-related details to others. The All-in-One guide similarly states that anything you see or are told should be treated as a “personal confidence” and not repeated to customers or others, underscoring why option A is inappropriate. Mike Meyers’ Lab Manual echoes this privacy expectation: treat what you see as confidential and handle customers’ private materials appropriately. Option B dismisses the customer’s concern, and option D is unprofessional and speculative.

Linux is the best choice for a low-cost home lab built from used PCs because it is free/open source and widely used in server environments, making it ideal for practicing server administration and scripting. Quentin Docter explains that Linux was created as a free, open source OS and that it can function as both a workstation OS and a server OS depending on installation and configuration—exactly what a lab for “managing servers” needs. The All-in-One guide also highlights that Linux was made “freely available for everyone,” reinforcing why it fits a low-cost requirement (no licensing cost). Mike Meyers’ Lab Manual similarly describes Linux as a “popular, free, open source” OS and emphasizes the importance of the command line—critical for scripting and automation in admin tasks.

By comparison, macOS requires Apple hardware, Windows typically requires licensing costs, and ChromeOS is designed as a cloud-based/stateless OS centered on web apps and Google Drive, making it less suitable for broad server scripting labs.

The correct answer is A. DLP (Data Loss Prevention), because DLP solutions are specifically designed to detect, monitor, and prevent unauthorized transmission of sensitive data outside an organization. Information exfiltration occurs when confidential data is improperly transferred, leaked, or stolen, either intentionally or accidentally.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, DLP technologies enforce policies that restrict how data can be shared via email, cloud services, removable media, or network transfers. DLP systems can block, quarantine, or alert administrators when sensitive data patterns—such as credit card numbers or personal identifiers—are detected leaving the organization.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that DLP focuses on data protection, not user authentication or device management. While IAM controls access to resources and MDM manages mobile devices, neither directly prevents data from being exfiltrated once access is granted.

The Mike Meyers / Mark Soper Lab Manual reinforces that SAML is an authentication framework and does not monitor data movement.

Because the question specifically addresses information exfiltration, the security control designed to prevent it is Data Loss Prevention, making A the correct answer.

The best tool is SSH (Secure Shell) because the scenario requires running command-line instructions on a remote network switch and capturing the text output. SSH provides a secure, encrypted remote terminal session (TCP port 22) that is commonly used to administer Linux/UNIX systems and networking equipment, making it ideal for switches that are typically managed through a CLI. Quentin Docter explicitly notes that ssh.exe launches the Secure Shell client and that it allows you to connect to a Linux/UNIX server or networking equipment, and he explains that SSH encrypts communications for secure text-console remote access. Mike Meyers’ Lab Manual reinforces that Telnet/SSH enable you to connect to a “server or fancy router” to run commands remotely, and that SSH is the secure modern alternative because the session is encrypted. The All-in-One guide also emphasizes SSH as the encrypted replacement for Telnet and highlights its use for remote command-line administrative tasks. By contrast, RDP and VNC are graphical remote-desktop tools, and WinRM is Windows-specific remote management rather than a standard switch-access method.
