An administrator is tasked with protection of a business critical application. The application is running on a Linux VM and is using a custom DB that require application consistent snapshots for data integrity.
An administrator has written a pre_freeze and post_thaw scripts and placed them under /usr/local/sbin/.
During protection domain scheduled run an alert is generated:
Execution of the PostThaw Script Failed

Correct Answer:
C, D
To resolve issues with application-consistent snapshots (script execution failures), two critical actions are needed:
NGT Service Status:
From the ECA materials:
''The Nutanix Guest Tools (NGT) service is responsible for executing pre-freeze and post-thaw scripts for application-consistent snapshots. If NGT is not running, these scripts will not execute.''
Script Validation:
''Before relying on scheduled snapshot runs, execute pre-freeze and post-thaw scripts manually to ensure they complete successfully. This helps to rule out script logic or permission issues.''
Ownership or log review of the script path itself (A and B) are secondary and typically not root-cause resolution steps.
