A field surveyor uses a specialized GIS mapping application on an enterprise iOS tablet to collect spatial terrain data. During operation, the application frequently stops responding, causing thermal throttling and accelerated battery discharge on the device. Following CompTIA troubleshooting methodology, in what sequence should the technician perform the following steps, ordered from least invasive to most invasive?
- 1Force close the GIS mapping application using the app switcher.
- 2Perform a soft reset by restarting the mobile device.
- 3Check for and install pending application updates and mobile operating system patches.
- 4Reinstall or offload the mapping application.
- 5Back up user data and perform a full factory reset of the tablet.
Cevap
The proper troubleshooting order from least invasive to most invasive is: 1) Force close the application, 2) Restart (soft reset) the mobile device, 3) Install application and OS updates, 4) Reinstall the application, and 5) Perform a factory reset.
CompTIA troubleshooting methodology dictates progressing from the least disruptive action to the most disruptive action. Force closing the application is the quickest, least invasive step. If the problem persists, soft resetting the device clears shared system memory. Installing updates fixes software bugs. Reinstalling the app replaces corrupted files, and performing a factory reset is the final, most invasive step.
