最近、スマートフォンのモバイル OS をアップグレードした後、ユーザーが会社のメールにアクセスしようとしましたが、アプリケーションが開きません。技術者がスマートフォンを再起動しましたが、問題は解決しません。この問題を解決するには、次のうちどれが最も可能性が高いでしょうか。
正解:A
Comprehensive and Detailed In-Depth When a mobile OS is updated, some applications may become incompatible or corrupted due to changes in system files. The best solution is to update the failed software, as the app developer may have released a patch to resolve compatibility issues. B . Registering the smartphone with an MDM solution - Incorrect. MDM (Mobile Device Management) helps with security policies but does not fix application compatibility issues. C . Installing a third-party client - Incorrect. Using a different app may work but does not resolve the root cause of the issue. D . Clearing the cache partition - While clearing the cache can help with performance, it is unlikely to resolve an application not opening due to an OS update.
