Question 1 of 3 · Mobile devices and computer hardware

A laptop charges normally with its original USB-C adapter. On a compatible dock, data and video work, but the battery drains under load. The dock delivers less power than the laptop requires. Which change addresses the evidence with the least disruption?

Answer and explanation

Best answer: Use a supported dock or power arrangement with sufficient delivered wattage

The measured power shortfall explains discharge under load even though data and video work. Use a supported arrangement that meets the laptop power requirement.

Why the other choices fit less well

Battery replacement is premature when the measured charging input is insufficient. Stable video does not indicate a graphics-driver fault; reducing refresh rate without checking the required and delivered wattage does not establish a supported charging arrangement.

USB-IF: power delivery

Question 2 of 3 · Operational procedures

A user asks you to reset a slow laptop. Their only copy of an important folder is on its internal drive. What should you do before starting a potentially destructive reset?

Answer and explanation

Best answer: Back up the required files and verify that the backup can be read

Preserve the required data and verify the backup before a destructive operation. Confirm the destination and that the files open; an unverified backup is an assumption.

Why the other choices fit less well

A reset can remove data before recovery is possible. A renamed folder remains on the same drive. Cloud sync must be checked rather than presumed to cover local files.

Microsoft: reset your PC

Question 3 of 3 · Network troubleshooting

A workstation can reach a service by IP address, but a lookup of its hostname against the configured DNS server fails. Other users can resolve the name. Which check best follows this evidence?

Answer and explanation

Best answer: Inspect the workstation DNS-server configuration and test that resolver

The successful IP connection narrows the investigation. Check which resolver this workstation uses and query it directly before making a wider change.

Why the other choices fit less well

Display cabling does not resolve hostnames. A working service for other users does not justify reinstalling it. Successful IP communication contradicts the claim that all connectivity has failed.

Microsoft: nslookup
