CompTIA 220-1201 Practice Test 36
Question 350
A support request at Aster Systems presents this problem: A monitor intermittently goes black when its display cable is moved. The supporting record states that the computer remains running and a spare certified video cable is available. The desired outcome is to determine whether a physical video link is causing intermittent display loss. The technician must document observations separately from assumptions. Which verification result supports the intended technical outcome?
- Verify the projector shows the test slide and remains stable in the selected mode
- Verify movement no longer causes signal loss at the intended resolution
- Verify text edges become sharp while interface size remains usable
- Verify internal brightness returns while external video remains unaffected
Explanation
Correct Answer
B:
Verify movement no longer causes signal loss at the intended resolution. It proves the required function with an observable result instead of assuming the change worked. The relevant observation is that the computer remains running and a spare certified video cable is available. The support goal is to determine whether a physical video link is causing intermittent display loss; this validate action specifically addresses intermittent monitor image due to video cable without confusing a different subsystem.
Incorrect Answers
A:
Verify the projector shows the test slide and remains stable in the selected mode. This action is appropriate for projector wrong input versus computer failure, normally when a conference room projector displays a no-signal message while the laptop works locally. Here the observed facts require intermittent monitor image due to video cable instead.
C:
Verify text edges become sharp while interface size remains usable. This action is appropriate for wrong screen resolution and scaling, normally when a user complains that desktop text is blurry after changing to a nonnative display resolution. Here the observed facts require intermittent monitor image due to video cable instead.
D:
Verify internal brightness returns while external video remains unaffected. This action is appropriate for backlight failure on laptop lcd, normally when a laptop screen looks black but a flashlight reveals a faint intact desktop image. Here the observed facts require intermittent monitor image due to video cable instead.
Question 351
On a service ticket for Lakeside Analytics, the team observes: A desktop shows a 169.254.x.x address and can see a nearby printer but cannot reach the router. The desired outcome is to recognize IPv4 link-local APIPA as a DHCP reachability symptom. The customer requires a verified fix rather than a guess based on one symptom. Which controlled service test best evaluates the planned approach?
- Sketch a hypothetical watch-to-phone, office switch, and remote-site circuit topology
- Test local peer connectivity and a routed test destination after correcting the gateway
- Renew the IP configuration on a test client after reconnecting to a working DHCP scope
- Pilot association and isolation with approved modern and legacy test clients
Explanation
Correct Answer
C:
Renew the IP configuration on a test client after reconnecting to a working DHCP scope. It tests the proposed solution safely on an approved representative system. The relevant observation is that a desktop shows a 169.254.x.x address and can see a nearby printer but cannot reach the router.

B:
Test local peer connectivity and a routed test destination after correcting the gateway. That action is appropriate for ipv4 subnet mask and gateway selection, normally when a small office workstation has 192.168.10.80/24 and a gateway incorrectly set to 192.168.11.1. Here the observed facts require apipa 169.254.x.x missing dhcp lease instead.
D:
Pilot association and isolation with approved modern and legacy test clients. That action is appropriate for soho wireless wpa security setup, normally when a small office access point still allows WEP while newer managed clients support WPA3-Personal.

The relevant observation is that a desktop stops at a boot-device prompt after an extra blank SSD is installed. The support goal is to restore the intended boot entry without formatting healthy storage; this diagnose action specifically addresses uefi boot order after a second drive without confusing a different subsystem.
Incorrect Answers
A:
Check M.2 socket specifications, BIOS PCIe settings, lane sharing and drive keying. That action is appropriate for nvme ssd not detected after installation, normally when a new NVMe SSD is absent from firmware and the storage installer. Here the observed facts require uefi boot order after a second drive instead.
B:

Question 354
A support request at Orchard Services presents this problem: A repair shop accidentally ships laptop-size RAM to a tower PC that takes full-size modules. The desired outcome is to recognize memory module form factors and physical socket compatibility. Service work must follow power isolation, ESD, and manufacturer instructions when applicable. What should be tracked after the fix to maintain service reliability?
- Monitor corrected memory events and growing error rates
- Monitor remaining SSD health and firmware updates
- Monitor unsupported module combinations and BIOS fallback settings
- Monitor inventory bins for mixed laptop and desktop memory modules
Explanation
Correct Answer
D:
Monitor inventory bins for mixed laptop and desktop memory modules. It tracks recurrence of the specific failure mechanism over time. The relevant observation is that a repair shop accidentally ships laptop-size RAM to a tower PC that takes full-size modules. The support goal is to recognize memory module form factors and physical socket compatibility; this monitor action specifically addresses sodimm versus dimm form factor without confusing a different subsystem.
Incorrect Answers

Monitor corrected memory events and growing error rates. This action is appropriate for ecc memory error correction compatibility, normally when a workstation used for scientific computation requires supported correction of single-bit RAM errors. Here the observed facts require sodimm versus dimm form factor instead.
B:
Monitor remaining SSD health and firmware updates. This action is appropriate for ssd versus hdd latency and interface, normally when a mobile user needs low-latency storage and shock resistance but a procurement request specifies a 5400 RPM hard disk. Here the observed facts require sodimm versus dimm form factor instead.
C:
Monitor unsupported module combinations and BIOS fallback settings. This action is appropriate for ddr generation electrical compatibility, normally when a replacement RAM order has the correct capacity but the wrong DDR generation. Here the observed facts require sodimm versus dimm form factor instead.
Question 355
A support request at Lakeside Analytics presents this problem: A desktop shows a 169.254.x.x address and can see a nearby printer but cannot reach the router. The desired outcome is to recognize IPv4 link-local APIPA as a DHCP reachability symptom. The customer requires a verified fix rather than a guess based on one symptom.

The desired outcome is to correct printer job configuration rather than replacing hardware. The technician must document observations separately from assumptions. Which configuration or repair action best addresses the stated requirement?
- Set the intended paper tray, form size and two-sided mode in driver or print server
- Require authenticated badge or PIN release of sensitive print jobs
- Replace the correct laser toner cartridge and recalibrate if indicated
- Run manufacturer-approved printhead cleaning before considering component replacement
Explanation
Correct Answer
A:

Here the observed facts require printer duplex and tray settings instead.
Question 359
At Clearwater Telecom, a technician working in computer equipment refresh identifies this issue: A gaming user buys a high-resolution screen but is disappointed that the interface still runs at 60 Hz. The desired outcome is to differentiate image pixel count from screen updates per second. The customer requires a verified fix rather than a guess based on one symptom. Which inspection most directly confirms the likely cause before changing components?
- Inspect UEFI Secure Boot state, key database and boot entries separately
- Compare IPS and TN viewing-angle color shifts, calibration and target workload
- Inspect horizontal and vertical pixel dimensions separately from rated Hz and link support
