CompTIA 220-1201 Practice Test 7
Question 60
A support request at Evergreen Manufacturing presents this problem: A user's phone receives mail but calendar edits never appear on the company laptop. The supporting record states that both devices use different cloud accounts despite similarly named calendar applications. The desired outcome is to restore synchronization by matching the authorized account and sync service. Any configuration change must be reversible and validated on a controlled test device. Which safe pilot action gives the most relevant evidence?
- Create one harmless test appointment and synchronize through the chosen enterprise account
- Activate the eSIM on a spare enrolled phone using an approved carrier test profile
- Pilot managed work apps with a consented BYOD phone and an unprotected personal app
- On a powered-off service unit, reseat the antenna leads with the correct nonconductive tool
Explanation
Correct Answer
A:
Create one harmless test appointment and synchronize through the chosen enterprise account. It tests the proposed solution safely on an approved representative system. The relevant observation is that both devices use different cloud accounts despite similarly named calendar applications. The support goal is to restore synchronization by matching the authorized account and sync service; this pilot action specifically addresses mobile calendar and contact synchronization without confusing a different subsystem.
Incorrect Answers
B:
Activate the eSIM on a spare enrolled phone using an approved carrier test profile. This action is appropriate for mobile esim carrier activation, normally when a company phone has cellular signal bars but cannot attach to its assigned business data plan. Here the observed facts require mobile calendar and contact synchronization instead.
C:
Pilot managed work apps with a consented BYOD phone and an unprotected personal app. This action is appropriate for byod mobile application management, normally when staff use personally owned phones to read corporate mail but refuse full device enrollment. Here the observed facts require mobile calendar and contact synchronization instead.
D:
On a powered-off service unit, reseat the antenna leads with the correct nonconductive tool. This action is appropriate for laptop wi-fi antenna reconnection, normally when after a laptop display assembly replacement, Bluetooth works but Wi-Fi signal is very weak. Here the observed facts require mobile calendar and contact synchronization instead.
Question 61
On a service ticket for Northland Labs, the team observes: A workstation loses Ethernet connection whenever its patch lead is bent. The supporting record states that switch counters show link up/down events and interface errors but its IP settings are valid. The desired outcome is to isolate physical cable or connector failure before changing network services. The customer requires a verified fix rather than a guess based on one symptom. How should the solution first be tested on an approved spare or pilot system?
- Use a certified spare patch cable and run a non-destructive cable wiremap test
- Resolve an approved internal hostname from a test client using the corrected DNS server
- Run a short controlled load test after servicing cooling on a lab desktop
- Pilot an alternate AP channel in a safe window while measuring client retry rate
Explanation
Correct Answer
A:

C:
Run a short controlled load test after servicing cooling on a lab desktop. This action is appropriate for cpu overheat from failed fan, normally when a desktop shuts off only after several minutes of high CPU utilization. Here the observed facts require copper ethernet link flapping instead.
D:
Pilot an alternate AP channel in a safe window while measuring client retry rate. This action is appropriate for intermittent wi-fi due to channel interference, normally when users near a lunchroom suffer slow 2.4 GHz Wi-Fi at peak periods while wired links stay normal. Here the observed facts require copper ethernet link flapping instead.
Question 62
At Acorn Foods, a technician working in end-user troubleshooting identifies this issue: A technician finds a compacted pocket-lint plug inside a handset charging receptacle. The desired outcome is to isolate a connector obstruction without damaging live charging contacts. A safe non-destructive test must be used before replacing additional parts.

Question 68
A support request at Pioneer Markets presents this problem: A desktop repair requires replacement memory but the spare part comes from a notebook. The supporting record states that the desktop has full-length DIMM sockets and the spare is a short SODIMM. The desired outcome is to recognize memory module form factors and physical socket compatibility. The goal is to restore required function without creating a new security or safety problem. What should the technician recommend as the corrective approach?
- Select a qualified DDR4 module of a supported configuration rather than DDR5
- Specify a platform that explicitly supports and enables ECC where required
- Use the correct desktop DIMM rather than forcing a laptop SODIMM into the socket
- Use supported single-mode fiber and matched long-reach optics for the kilometer-scale link
Explanation
Correct Answer
C:
Use the correct desktop DIMM rather than forcing a laptop SODIMM into the socket. It corrects the documented cause using the compatible technology and support constraints.
