Computer Systems Final — Core 1 + Core 2 Integrated Review

Forty cumulative questions across the entire course. This final emphasizes technician reasoning, troubleshooting, evidence selection, and support decisions rather than isolated certification trivia.Automatic score only. Nothing is submitted or stored as a learner grade.
  1. 1. A workstation will not power on after being moved. No LEDs or fans respond. What should be checked first?
  2. 2. A PC emits a memory-related POST error immediately after a RAM upgrade. What is the strongest first theory?
  3. 3. Why must an M.2 replacement be checked against motherboard documentation?
  4. 4. A desktop repeatedly shuts down only during high CPU/GPU load. Which evidence should be checked early?
  5. 5. A monitor works on another PC, and the original PC works through a different video port. What does that evidence suggest?
  6. 6. A laptop's internal screen is dark, but an external display works normally. Which area deserves attention?
  7. 7. A phone battery is visibly swollen. What should happen?
  8. 8. A corporate phone must enforce encryption, screen lock, approved apps, and remote wipe. Which technology best supports that requirement?
  9. 9. A phone has working internet access, but only one app refuses to sync. What should be investigated first?
  10. 10. A laser printer produces pages where toner rubs off. Which component is most suspect?
  11. 11. Several users have jobs stuck in one shared printer queue. Which shared subsystem should be checked first?
  12. 12. A multifunction printer can scan locally but scan-to-folder fails. Which dependency should be checked?
  13. 13. What is the primary role of a switch in a basic LAN?
  14. 14. What is the primary role of a router?
  15. 15. A client receives 169.254.30.8 and has no default gateway. What is the strongest initial diagnosis?
  16. 16. A host can ping its gateway and a remote IP, but `nslookup` fails. Which service should be investigated?
  17. Layered network-service dependency diagram separating client addressing, gateway path, DNS, transport ports, application service, and network controls.
    Visual evidence: The diagram separates basic IP reachability from application-service reachability. Identify the deepest boundary the evidence actually proves.
    17. Use the network-service stack. A server responds to ping, but TCP port 443 is not reachable. What has been proven?
  18. 18. Which tool is most appropriate for seating twisted-pair conductors into an IDC keystone jack?
  19. 19. Voice calls sound choppy even though average bandwidth is adequate. Which network measurement is especially relevant?
  20. 20. A technician wants to test an application without changing the primary workstation. What is an appropriate environment?
  21. 21. Several VMs are slow and the host is out of available memory. What is the strongest theory?
  22. 22. Which cloud service model leaves the customer responsible for the virtual machine operating system and applications?
  23. 23. Which Windows tool is best for investigating a hardware device warning after a driver update?
  24. 24. A Windows client reaches a known IP but not a hostname. Which command is useful next?
  25. 25. What does FileVault provide on macOS?
  26. 26. A Linux service reports a configuration parsing error. What should be checked before reinstalling the OS?
  27. 27. What is the strongest cross-platform troubleshooting habit?
  28. 28. A user needs an application but no administrative duties. Which account design follows least privilege?
  29. 29. An application needs one inbound firewall port. What is the best response?
  30. 30. A text message claiming to be IT asks the user to send an MFA code. What should the user/technician do?
  31. 31. A browser starts redirecting after an unknown extension is installed. What is a safe first response?
  32. 32. A retired drive with confidential data will be disposed of. Why is normal file deletion not enough?
  33. 33. A Windows system displays ‘No operating system found.’ Which boundary should be investigated before browser settings?
  34. 34. Only one user profile takes several minutes to load; other profiles are normal. What does that suggest?
  35. 35. A mobile app update fails because the device has no free storage. What is the smallest justified correction?
  36. 36. A browser displays fake antivirus warnings while approved endpoint protection is active. What should the technician do?
  37. 37. Before starting remote support, what must be established?
  38. 38. A script will update configuration on many systems. What is the safest operational approach?
  39. 39. An AI assistant suggests a command that would delete a configuration directory. What should a technician do?
  40. 40. What is the strongest evidence that the final Technician Service Challenge is complete?
