Q: A technician needs to provide remote support for a legacy Linux-based operating system from their Windows laptop. The solution needs to allow the technician to see what the user is doing and provide the ability to interact with the user's session. Which of the following remote access technologies would support the use case?

B. VNC. VNC (Virtual Network Computing) is a platform-independent remote desktop protocol that works across different operating systems, including Windows-to-Linux connections. It transmits screen images and input events, allowing the technician to see and interact with the user's session. SSH provides command-line access only — no graphical session viewing or interaction with an existing user session. RDP is Microsoft's proprietary protocol and has limited or no native support on legacy Linux systems. VPN is a network tunneling tool, not a remote control solution — it connects networks, not sessions. VNC directly satisfies both requirements: cross-platform support and visual, interactive session access.

Q: A technician is attempting to join a workstation to a domain but is receiving an error message stating the domain cannot be found. However, the technician is able to ping the server and access the internet. Given the following information: 220-1202_002.png Which of the following should the technician do to fix the issue?

A. Change the DNS settings.. The technician can ping the server (192.168.1.10) and access the internet, which confirms the IP address, subnet mask, and gateway are all correct. Domain joining requires DNS to resolve the domain controller's hostname — the workstation must be able to look up the domain name in Active Directory. The current DNS servers are 8.8.8.8 (Google) and 1.1.1.1 (Cloudflare) — both are public internet DNS servers that have no knowledge of the internal domain. The internal DNS server (likely running on the domain controller at 192.168.1.10) is what resolves Active Directory domain names. The fix is to change DNS1 to 192.168.1.10 so the workstation queries the internal DNS server. A static IP is already effectively set, the subnet mask is correct, and the gateway is functional since internet access works.

Q: A network technician notices that most of the company's network switches are now end-of-life and need to be upgraded. Which of the following should the technician do first?

C. Propose the change.. The change management process follows a specific order: propose → approve → schedule → implement. Before anything else, the technician must formally propose the change so it can be reviewed. Approving comes after a proposal exists. Scheduling happens only after approval. Implementing is the last step. Skipping proposal violates change control policy.

Q: MFA for a custom web application on a user's smartphone is no longer working. The last time the user remembered it working was before taking a vacation to another country. Which of the following should the technician do first?

A. Verify the date and time settings.. TOTP-based MFA apps generate codes using the device's clock. If the clock is wrong after traveling to a different time zone, the codes will be invalid. This is the most common MFA failure after international travel. Patching, reinstalling, or escalating are premature before checking the simplest cause. Time sync is always the first check for MFA failures.

Q: Which of the following is found in an MSDS sheet for a battery backup?

B. Emergency procedures. An MSDS (Material Safety Data Sheet), now called SDS, documents hazardous materials and their safe handling. Emergency procedures cover what to do in case of fire, spill, or exposure. Installation instructions and configuration steps are not safety documents. Voltage specifications belong in a technical datasheet. MSDS/SDS is strictly a safety and hazard document.
