SIMULATION

You are configuring a home network for a customer. The customer has requested the ability to access a Windows PC remotely, and needs all chat and optional functions to work in their game console.

INSTRUCTIONS

Use the drop-down menus to complete the network configuration for the customer. Each option may only be used once, and not all options will be used.

Then, click the + sign to place each device in its appropriate location.

If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.

Wireless AP LAN



Firewall Screened Subnet



  1. See Explanation section for answer.

Answer(s): A

Explanation:

The completed configuration:
1. Wireless AP (LAN side)
1. LAN IP: 192.168.10.1
2. Encryption: WPA2 PSK
2. Router (port-forward rule)
1. Allow TCP Any 3389
This forwards inbound RDP traffic (TCP/3389) from the Internet to the Windows PC, enabling Remote Desktop access.
3. Firewall (screened subnet side)
1. LAN IP: 10.100.0.1
4. Device placement
1. PC: place behind the router (where the port-forward rule points).
2. Game console: place on the Wireless AP (so it can use chat and extra services over WPA2 PSK).
3. Firewall: place in front of the screened subnet (with its 10.100.0.1 IP facing that subnet).



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?

  1. VPN
  2. VNC
  3. SSH
  4. RDP

Answer(s): B

Explanation:

VNC (Virtual Network Computing) provides graphical remote desktop access across platforms, allowing the technician on a Windows machine to both view the Linux desktop in real time and interact with the user's session (mouse/keyboard control).



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:



Which of the following should the technician do to fix the issue?

  1. Change the DNS settings.
  2. Assign a static IP address.
  3. Configure a subnet mask.
  4. Update the default gateway.

Answer(s): A

Explanation:

Domain join failures with successful IP connectivity almost always point to name-resolution issues. The workstation is using public DNS servers (8.8.8.8 and 1.1.1.1), which have no records for the internal AD domain or its controllers. Pointing DNS at the internal DNS server (192.168.1.10) ensures the domain name and SRV records can be resolved, allowing the join to succeed.



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?

  1. Implement the change.
  2. Approve the change.
  3. Propose the change.
  4. Schedule the change.

Answer(s): C

Explanation:

In a structured change-management process, the very first step is to propose (or formally request) the change via a Request for Change (RFC). This ensures stakeholders review the need, assess risks, and determine the priority before any approvals, scheduling, or implementation occur.



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?

  1. Verify the date and time settings.
  2. Apply mobile OS patches.
  3. Uninstall and reinstall the application.
  4. Escalate to the website developer.

Answer(s): A

Explanation:

Time-based one-time password (TOTP) MFA apps rely on accurate clock synchronization. Traveling can desynchronize the device's clock, causing generated codes to be invalid. Ensuring the smartphone's date/time (and time zone) are correct will typically restore MFA functionality immediately.



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

  1. Installation instructions
  2. Emergency procedures
  3. Configuration steps
  4. Voltage specifications

Answer(s): B

Explanation:

A Material Safety Data Sheet (MSDS) provides critical safety and handling information for hazardous materials
- in this case, the battery's chemicals. It includes emergency procedures (first-aid measures, fire-fighting steps, spill containment), ensuring responders know how to act safely in an incident.



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?

  1. Run data recovery tools on the disk.
  2. Partition the disk using the GPT format.
  3. Check boot options.
  4. Switch from UEFI to BIOS.

Answer(s): C

Explanation:

An "OS Not Found" error most commonly indicates the system isn't booting from the correct device. Verifying and correcting the boot order (ensuring the internal hard drive is prioritized over USB or other entries) is the quickest first step before making any changes to the disk or firmware settings.



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?

  1. To ensure that all removable media is password protected in case of loss or theft
  2. To enable Secure Boot and a BIOS-level password to prevent configuration changes
  3. To enforce VPN connectivity to be encrypted by hardware modules
  4. To configure all laptops to use the TPM as an encryption factor for hard drives

Answer(s): A

Explanation:

BitLocker To Go is specifically designed to encrypt removable drives (USB flash drives, external HDDs).
Training staff on its use guarantees that any data stored on such media requires a password (or recovery key) to access, protecting sensitive information if the device is lost or stolen.
