Which two statements about the integrity of databases on FortiManager are correct? (Choose two.)

The integrity of the FortiManager databases is critical for stable operation, successful upgrades, and reliable backups.

Statement (C) is correct because FortiManager database schemas can change significantly between major versions. The upgrade process includes scripts to migrate the database to the new schema. Skipping versions in the upgrade path means these migration scripts may not run or may fail, leading to data corruption and database inconsistencies.

Statement (B) is also correct. As a built-in safeguard, the FortiManager system automatically performs a database integrity check before executing a backup task. If this check fails, the backup process is aborted to prevent creating a backup of a corrupted or inconsistent database, which would be unreliable for a future restore.

A. The diagnose dvm check-integrity command is a diagnostic tool that reports inconsistencies within the Device Manager (DVM) database, not the underlying file system. It does not perform any corrective actions.

D. While it is a mandatory prerequisite to fix integrity issues before a backup can succeed (as the backup will fail otherwise), statement B describes the actual system process that enforces this, making it a more direct and accurate statement about the system's behavior.

E. The diagnose cdb check adom-integrity command is used to identify and report integrity problems within a specific ADOM's database. It does not have the functionality to correct issues, such as unlocking devices.

1. FortiManager Administration Guide 7.4.1

Page 101

"Backing up the FortiManager system": "Before backing up the configuration

FortiManager runs a database integrity check. If the check fails

the backup is not created." This directly supports answer B.

2. FortiManager Upgrade Guide 7.4.1

Page 5

"Upgrade path": "You must follow the supported upgrade path. If you do not follow the supported upgrade path

you will have issues with the upgrade." This section emphasizes the requirement to follow a specific path to prevent issues

which includes database inconsistencies

supporting answer C.

3. FortiManager CLI Reference 7.4.1

Page 130

"diagnose dvm check-integrity": The description for this command is "Check device manager database integrity." It details the syntax for checking but includes no parameters or descriptions for fixing or repairing

which supports the reasoning for A being incorrect.

4. FortiManager CLI Reference 7.4.1

Page 108

"diagnose cdb check adom-integrity": The description is "Check ADOM integrity." Similar to other diagnostic commands

its purpose is to report status

not to perform corrective actions

which supports the reasoning for E being incorrect.
