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?
A
VPN
B
VNC
C
SSH
D
RDP
Correct Answer:
B. VNC
Explanation:
The correct answer is B. VNC.
Here's why:
VNC (Virtual Network Computing): VNC is a graphical desktop sharing system that allows you to remotely
control the screen and keyboard of another computer. In this scenario, the technician needs to see what the
user is doing and interact with their session. VNC directly provides this functionality by sharing the graphical
output of the Linux machine with the technician's Windows laptop, enabling remote control.
Why the other options are less suitable:
VPN (Virtual Private Network): A VPN establishes a secure tunnel between two networks. While it's useful for
secure remote access, it doesn't inherently provide screen sharing or remote control capabilities. The
technician would need another tool in conjunction with the VPN.
SSH (Secure Shell): SSH is a secure protocol used for command-line access to a remote server. While useful
for administration, it doesn't provide a graphical interface for viewing the user's session.
RDP (Remote Desktop Protocol): RDP is primarily used for connecting to Windows systems. While there are
RDP clients for Linux, RDP is not the native remote access solution for Linux, and ensuring compatibility with a
legacy Linux system could be problematic. It is designed primarily for Windows to Windows communication.
In summary, VNC is the most appropriate solution as it provides the necessary screen sharing and remote
control functionality for a Windows technician to support a legacy Linux user. VNC can be configured for both
operating systems and allows for real-time interaction with the users environment, aligning with the stated
requirements in the question.

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:
A
Change the DNS settings.
B
Assign a static IP address.
C
Configure a subnet mask.
D
Update the default gateway.
Correct Answer:
A. Change the DNS settings.
Explanation:
A. Change the DNS settings
If a technician determines that the issue is related to DNS, it typically means:
The device can reach the internet by IP address (e.g., 8.8.8.8 works)
But it cannot reach websites by name (e.g., google.com fails)
Network connectivity (gateway, IP, subnet mask) is fine
Only name resolution is failing
This indicates the DNS server configuration is incorrect or unreachable.
Update the DNS settings, often to:
The company’s internal DNS server
Or public DNS servers like 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
Why the other options are incorrect:
B. Assign a static IP address
Not needed unless:
There is a DHCP failure
Or IP conflicts
Or the device is losing its address
None of these relate to DNS lookup issues.
C. Configure a subnet mask
A bad subnet mask causes:
Inability to reach systems on the same network
General network communication failures
This does not only affect name resolution.
D. Update the default gateway
A wrong gateway causes:
Inability to reach other networks or the internet
But the symptom would be general connectivity failure, not specifically DNS lookup failures.
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?
A
Implement the change.
B
Approve the change.
C
Propose the change.
D
Schedule the change.
Correct Answer:
C. Propose the change.
Explanation:
C. Propose the change.
In IT change-management processes, the first step is always to propose or submit the change request.
Even if the switches are end-of-life and clearly need replacement, the technician must follow proper
procedure:
Propose the change (create the change request with justification, impact, cost, and plan)
Approve the change (management/Change Advisory Board review)
Schedule the change (plan outage/maintenance window)
Implement the change (perform the work)
Therefore, the technician's first action is to propose the change.
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.
B
Apply mobile OS patches.
C
Uninstall and reinstall the application.
D
Escalate to the website developer.
Correct Answer:
A. Verify the date and time settings.
Explanation:
A. Verify the date and time settings.
Explanation
Most MFA apps (Google Authenticator, Microsoft Authenticator, TOTP apps, etc.) rely on time-based one-time
passwords (TOTP).
If the smartphone's date, time, or time zone is incorrect - which commonly happens after traveling
internationally- the MFA codes will be out of sync and authentication will fail.
This is the most common and easiest first check, and it matches the scenario:
User traveled to another country
Time zone changed
MFA stopped working afterward
So the technician should first verify and correct the date/time settings, preferably setting them to automatic.
Why the other answers are incorrect
B. Apply mobile OS patches
Not related to TOTP issues.
C. Uninstall and reinstall the application
Unnecessary and risks losing MFA tokens if backup is not configured.
D. Escalate to the website developer
Not appropriate - the issue is almost certainly on the user's device.
Which of the following is found in an MSDS sheet for a battery backup?
A
Installation instructions
B
Emergency procedures
C
Configuration steps
D
Voltage specifications
Correct Answer:
B. Emergency procedures
Explanation:
B. Emergency procedures
An MSDS (Material Safety Data Sheet)-now commonly called an SDS (Safety Data Sheet)-contains safety-
related information about hazardous materials.
For a battery backup (UPS), the MSDS/SDS will include:
Chemical composition
Hazards (fire, chemical, explosion)
Emergency procedures (spill cleanup, first aid, fire response)
Handling and storage guidelines
PPE requirements
Disposal instructions
It does not contain instructions on installing or configuring the device.
Why the other options are incorrect
A. Installation instructions
Not found in an MSDS - these are in the user manual.
C. Configuration steps
Also part of the device manual, not a safety document.
D. Voltage specifications
This is technical documentation, not part of the MSDS.
The screen of a previously working computer repeatedly displays an OS Not Found error message when the
computer is started. Only a USB drive, a keyboard, and a mouse are plugged into the computer. Which of the
following should a technician do first?
A
Run data recovery tools on the disk.
B
Partition the disk using the GPT format.
C
Check boot options.
D
Switch from UEFI to BIOS.
Correct Answer:
C. Check boot options.
Explanation:
C. Check boot options.
When a computer suddenly shows “OS Not Found”, the most common causes are:
The system is trying to boot from the wrong device (e.g., USB instead of internal drive)
The boot order changed
The primary drive is not being detected
The very first troubleshooting step is to:
Detected
Check the boot options / boot order in BIOS or UEFI
Because the only peripherals connected are USB devices, the system may be attempting to boot from one of
them.
Make sure the internal hard drive or SSD is:
Listed as the first boot device
A security administrator teaches all of an organization's staff members to use BitLocker To Go. Which of the
following best describes the reason for this training?
A
To ensure that all removable media is password protected in case of loss or theft
B
To enable Secure Boot and a BIOS-level password to prevent configuration changes
C
To enforce VPN connectivity to be encrypted by hardware modules
D
To configure all laptops to use the TPM as an encryption factor for hard drives
Correct Answer:
A. To ensure that all removable media is password protected in case of loss or theft
Explanation:
A. To ensure that all removable media is password protected in case of loss or theft
BitLocker To Go is Microsoft’s encryption feature specifically designed for:
USB flash drives
External hard drives
Other removable storage
Training staff to use BitLocker To Go helps ensure that all removable media is encrypted and requires a
password.
This protects data if a USB drive is:
Lost
Stolen
Misplaced
Used on another computer
This is exactly why an organization would train all employees to use it.
Which of the following is used to detect and record access to restricted areas?
A
Bollards
B
Video surveillance
C
Badge readers
D
Fence
Correct Answer:
B. Video surveillance
Explanation:
B. Video surveillance
The question asks for something that can detect and record access to restricted areas.
Video surveillance (CCTV):
Detects people entering restricted areas
Records them through video footage
Provides evidence and monitoring capability
This makes it the best match.
Why the other options are incorrect:
A. Bollards
Physical barriers to prevent vehicle access; they do not detect or record anything.
C. Badge readers
They detect and log access attempts, but they do not record video - only authentication logs.
Since the question says detect AND record, badge readers alone are not sufficient.
D. Fence
Provides a physical boundary; no detection or recording capability.
An administrator received an email stating that the OS they are currently supporting will no longer be issued
security updates and patches. Which of the following is most likely the reason the administrator received this
message?
A
Support from the computer’s manufacturer is expiring.
B
The OS will be considered end of life.
C
The built-in security software is being removed from the next OS version.
D
A new version of the OS will be released soon.
Correct Answer:
B. The OS will be considered end of life.
Explanation:
The correct answer is B, "The OS will be considered end of life." Here's why:
When an operating system reaches its "end of life" (EOL), it means the vendor (like Microsoft for Windows, or
Apple for macOS) will no longer provide updates, security patches, or support for that version. This is a critical
security risk because vulnerabilities discovered after the EOL date will not be fixed, making systems running
that OS susceptible to malware and attacks.
Option A is incorrect. While hardware manufacturer support expiring could be a concern, it's typically
separate from OS support. The OS itself may still be supported even if the specific computer model is not.
Option C is incorrect. The removal of built-in security software in a future OS version doesn't explain why the
current OS version is ceasing to receive updates. Security software changes usually happen with new OS
releases, not during the support lifecycle of an existing one.
Option D is incorrect. A new OS version being released is often a precursor to an older version reaching EOL, but
the email's message is specifically about the current OS no longer receiving security updates, indicating EOL
status. The release of a new OS causes the possibility of an older OS going EOL.
The email's message directly implies that the administrator's responsibility to maintain a secure and up-to-
date system is compromised, which is a hallmark of an OS reaching its end of life. Therefore, option B is the most
logical and direct explanation.

Explanation:
D. Use a network-based remote installation tool.
Deploying custom images to 800 devices with multiple:
Vendor classes (4 types)
User groups (2 types)
requires scalability, automation, and centralized management.
most efficient and realistic method because it:
Supports large-scale deployment
Reduces manual labor
A network-based remote installation tool (such as MDT, WDS, SCCM/MECM, or PXE boot deployment) is the
Allows multiple images for different hardware/vendor classes
Allows role-based or user-group–based customization
Ensures consistency across all devices
Works over the network without touching each machine physically
This is exactly what organizations use for mass deployments.
