156-315.81.20 Gateway Deployment and Upgrades Practice Question
An administrator needs to revert a Security Gateway to its exact state before a failed Jumbo Hotfix installation. Which recovery method is most appropriate if a 'Snapshot' was taken immediately before the update?
⚠ Common exam trap
Candidates frequently confuse Backups with Snapshots, failing to realize that standard backups may exclude critical OS binaries and low-level configuration states needed for complete rollback.
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
✓
Reverting to the Snapshot via the 'clish' or WebUI.
A Gaia Snapshot is a full image of the entire system, including the operating system, configuration, and product binaries. This makes it the most comprehensive recovery tool for failed upgrades or hotfix installations, as it returns the gateway to a known working state in a single step.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Restoring a 'Backup' file via the WebUI.
Why it's wrong here
A Gaia Backup only contains configuration files and the database; it does not include the operating system binaries or the software version. If a hotfix modified the system binaries and caused a failure, restoring a configuration backup would not fix the underlying software corruption or version mismatch.
- ✗
Performing a 'cpclean' and then reinstalling the base version.
Why it's wrong here
'cpclean' is used to remove Check Point products but does not restore the system to a previous state. Reinstalling the base version and reconfiguring everything manually is time-consuming and prone to error, making it much less efficient than simply reverting to a pre-existing system snapshot.
- ✓
Reverting to the Snapshot via the 'clish' or WebUI.
Why this is correct
Reverting to a snapshot is the fastest and most reliable way to recover from a failed software update. Because the snapshot contains the entire disk state, including the previous software version and all configuration files, the system will be identical to how it was before the hotfix was attempted.
- ✗
Using the 'fwm dbimport' command to restore the management database.
Why it's wrong here
The 'fwm dbimport' command is used on the Security Management Server to restore the management database, not on a Security Gateway to recover from a hotfix failure. Gateways do not store the master management database; they only store the local compiled policy and Gaia configuration.
