A company is testing the latest model of a laptop. After turning on the laptop, there is a noticeable burning smell.
Which of the following steps should a technician take to troubleshoot the laptop issue? (Choose two.)

  1. Turn it off and disconnect all power sources
  2. Submit an emergency request to the local facilities manager
  3. Check for foreign objects, liquid spills, and internal damage.
  4. Contact the vendor and submit a return request.
  5. Remove the device from the MDM
  6. Try an alternate AC adapter.

Answer(s): A,C

Explanation:

Turning off and disconnecting all power sources prevents further damage and ensures safety when diagnosing hardware issues.
Checking for foreign objects, liquid spills, and internal damage helps identify the physical cause of the burning smell.



A technician needs to figure out why a laser printer is intermittently not feeding paper to print. The technician verifies the issue by running several copy-and-print tests.
Which of the following should the technician do next?

  1. Update the printer drivers.
  2. Select the correct paper size.
  3. Clean the pickup rollers.
  4. Replace the toner cartridge.

Answer(s): C

Explanation:

Cleaning the pickup rollers restores proper friction for paper feeding and resolves intermittent feed failures.



Which of the following can be used to logically segment networks?

  1. MAC
  2. VLAN
  3. NIC
  4. DSL

Answer(s): B

Explanation:

VLANs create separate broadcast domains on the same physical network infrastructure, logically segmenting traffic without additional hardware.



After troubleshooting a computer's connectivity, the network team determines there is a port-flapping issue. After plugging the patch cable into a different port, the issue persists.
Which of the following troubleshooting steps should a technician take next to resolve the issue?

  1. Convert the patch cable to a crossover cable
  2. Test the patch cable from the computer to the network closet
  3. Verify the length of the patch cable meets current standards
  4. Replace the patch cable from the device to the wall

Answer(s): B

Explanation:

Testing the patch cable end-to-end (from the computer to the network closet) isolates whether the flapping is caused by a faulty cable segment before replacing hardware.



Which of the following statements best summarize managed vs unmanaged switches?

  1. Unmanaged switches are generally more expensive.
  2. Unmanaged switches have more security capabilities
  3. Unmanaged switches start working as soon as they are plugged in to the network.
  4. Managed switches have more features
  5. Managed switches require no configuration.
  6. Managed switches consume less power.

Answer(s): C,D

Explanation:

Unmanaged switches are plug-and-play devices that start forwarding traffic immediately upon connection,
requiring no configuration.
Managed switches offer advanced features, such as VLANs, QoS, and port security, that provide greater control and customization of network behavior.
