MD-102 Manage applications Practice Question
Exhibit
{
"kql": "DeviceAppHealth | where DeviceName == 'WIN10-PC' | where Timestamp > ago(1d) | project AppName, AppVersion, InstallationResult, ErrorCode"
}Refer to the exhibit. A KQL query is run in Microsoft Defender XDR for a device 'WIN10-PC'. The results show that a critical line-of-business app 'ContosoApp' version '2.0.0' has InstallationResult 'Failed' with ErrorCode '0x80073CF6'. What does this error code typically indicate?
⚠ Common exam trap
Candidates often confuse error codes related to package signing (0x80073CF6) with generic installation failures caused by permissions or disk space, but Microsoft specifically uses distinct error codes for each failure type, and the exam expects you to recognize the signature-corruption meaning of this hex value.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The app package is not signed correctly
Error code 0x80073CF6 in Microsoft Defender XDR corresponds to APPX_E_CORRUPT_CONTENT, which indicates that the app package's digital signature is invalid or the package content has been tampered with. This typically occurs when the .appx or .msix package is not signed correctly or the signature does not match the package contents, preventing installation on Windows 10/11 devices.
