A remote environmental surveyor reports that a mobile device running a custom geospatial data-logging application experiences severe performance degradation, frequent application freezing, and excessive battery drain during field operations. The device also feels unusually warm during use. Following the CompTIA least-invasive-first troubleshooting methodology, which TWO of the following initial actions should the technician take to resolve these symptoms?
- Force close the geospatial data-logging application and clear its app cache.Cevap
- Check for and install pending application updates from the enterprise mobile application catalog.Cevap
- CPerform a factory reset of the mobile device to reinstall the operating system.
- DRun a System File Checker (sfc /scannow) utility on the mobile device via a USB debugging console.
Cevap
The technician should force close the application and clear its cache, as well as verify and install pending application updates.
Targeted mobile application troubleshooting dictates starting with the least invasive resolution steps. Force quitting the malfunctioning app and clearing its cached data clears temporary state errors without deleting persistent data. Furthermore, applying pending software updates fixes known software defects that cause high processor load, overheating, and rapid battery discharge.
