Exam JN0-232 Topic 1 Question 42 Discussion

The SRX Series devices support third-party antivirus scanning engines such asAvira. To use the Avira antivirus engine, administrators must explicitly enable the engine and ensure that the required components are properly loaded.
* Enable in configuration mode:
* The Avira antivirus engine must be enabled under UTM configuration mode. This step ensures the SRX device uses the Avira scanning engine for antivirus inspection.
* Example:
* set security utm feature-profile anti-virus avira-engine enable
* Reboot the SRX device:
* A system reboot is required after enabling the Avira engine to load the Avira antivirus components into memory.
* Without a reboot, the Avira engine will not become active.
* Why not the others?
* Restarting themgdprocess (Option A) only reloads the management daemon and does not load antivirus engines.
* Enabling inoperational mode(Option B) is not supported; the configuration must be applied in configuration mode.
Therefore, the correct actions to use Avira Antivirus are:Enable the Avira engine in configuration mode (Option D) and reboot the SRX device (Option C).
