A customer needs to install a new printer in their network. The customer reports that users had intermittent connectivity issues with previous printers.
Which of the following should the technician configure on the new printer to prevent this issue?

  1. Gateway IP address
  2. DHCP IP address
  3. Static IP address
  4. Public IP address

Answer(s): C

Explanation:

Assigning a fixed (static) IP to the printer ensures it always resides at the same network address, eliminating the intermittent connectivity problems that can occur when DHCP leases expire or addresses change.



Which of the following DNS records would an administrator change to redirect email flow?

  1. MX
  2. TXT
  3. SPF
  4. CNAME

Answer(s): A

Explanation:

MX (Mail Exchanger) records specify which mail servers are responsible for receiving email for a domain.
Changing the MX record reroutes incoming email to the designated server.



A technician is troubleshooting a network issue. Users report that the connection keeps dropping and reconnecting every few seconds. The technician:

Verifies the network configuration settings are correct on the workstation

Tests the network cable from the workstation to the switch and finds no issues

Uses a known-good workstation on the existing network cable and replicates the reported issue

Which of the following should the technician do next?

  1. Add new network hardware to reduce congestion
  2. Assign a static IP to the impacted workstations.
  3. Validate the environment for external interference.
  4. Check the network logs for evidence of port flapping.

Answer(s): D

Explanation:

Since the NIC, cable, and workstation configuration have all been ruled out, and the problem persists even with a known-good PC on the same switch port, this behavior points to an unstable link at the switch itself (often called "port flapping"). Examining the switch's event or syslog will reveal if the port is constantly going up and down, confirming a hardware or configuration issue on the switch side.



Which of the following would prevent a virtual machine from communicating with any endpoints on a network or the internet?

  1. VDI
  2. Private cloud
  3. Sandbox
  4. Type 1 hypervisor

Answer(s): C

Explanation:

A sandbox is designed to isolate a virtual environment from the rest of the system and network. By default, it's cut off from external endpoints, preventing any network or internet communication and ensuring that code running inside cannot affect other resources.



A technician recently updated the firmware on a dual-BIOS motherboard. Following the update, the system has been stuck in a boot loop and cannot start an OS from any internal or external device. The technician cannot access the UEFI menu either.
Which of the following should the technician do next?

  1. Enable the secondary configuration.
  2. Downgrade the firmware via US
  3. Start a warranty repair of the motherboard.
  4. Reapply thermal paste to the CPU.

Answer(s): A

Explanation:

On a dual-BIOS motherboard, if the primary BIOS image becomes corrupt (such as after a failed update) the board can switch to its backup BIOS. Enabling or triggering the secondary BIOS lets you recover the system and reflash the primary chip without replacing hardware.
