   A technician is configuring a SOHO router and wants to only allow specific computers on the network. Which of the following should the technician do?

   • AConfigure MAC filtering.
   • BDisable DHCP.
   • CConfigure port forwarding.
   • DDisable guest access.

   Show answer

   Answer: A

   Explanation

   A. Configure MAC filtering. MAC filtering allows the router to restrict network access based on the MAC addresses of devices. By configuring MAC filtering, the technician can specify which computers are allowed to connect to the network, thereby ensuring only specific computers are granted access. Disabling DHCP, configuring port forwarding, and disabling guest access are not directly related to restricting access to specific computers on the network.

   • ADHCP reservation
   • BPort forwarding
   • CDNS A record
   • DNAT

   Show answer

   Answer: A

   Explanation

   I asked ChatGPT this question and this is the result If static IP addresses are not allowed, then the technician can use DHCP reservation to ensure that the server maintains the same IP address at all times. DHCP reservation is a feature available in most SOHO devices and it allows the technician to assign a fixed IP address to a specific device on the network. The device's MAC address is used to identify the device, and the DHCP server assigns the same IP address to that device every time it requests an IP address.

   A user reports receiving constant, unwanted pop-ups and being unable to close the browser window. These issues have impacted the user's productivity and may have caused the user's files to be altered. Which of the following should a technician do to address these issues with minimal impact to the user?

   • BWipe the computer and install a new copy of the OS.
   • CIdentify whether the disk partition table has been reduced in size.
   • DPerform a full-system, antivirus scan and check browser notifications.

   Show answer

   Answer: D

   Explanation

   D. Perform a full-system, antivirus scan and check browser notifications. Given the symptoms of unwanted pop-ups and potential file alterations, it's likely that the user's system is infected with malware. A full-system antivirus scan will help to identify and remove any malicious software that may be causing the issues. Additionally, checking browser notifications can help to identify and disable any malicious extensions or settings that may be triggering the pop-ups. While options like System Restore, reimaging the system, or checking disk partition size might be necessary in more severe cases, a full-system antivirus scan and browser check are the most appropriate initial steps in this scenario.
