The Local White reputation is assigned to files that are either pre-existing on the device before the sensor installation, or signed by a trusted certificate, or created by an IT tool. The file signature is verified by the sensor against a list of trusted certificates that are stored locally on the device. If the file is signed by a certificate that matches one of the trusted certificates, the sensor assigns the Local White reputation to the file. This reputation indicates that the file is trusted and allowed to run on the device. The other options are incorrect because they do not qualify for the Local White reputation. Option A is incorrect because adding a file as an IT tool does not automatically assign it the Local White reputation. The file must also be signed by a trusted certificate or pre-existing on the device. Option C is incorrect because the hash being not on any known good or bad lists is not relevant for the Local White reputation. The file must also be signed by a trusted certificate or pre-existing on the device. Option D is incorrect because the hash being previously analyzed is notrelevant for the Local White reputation. The file must also be signed by a trusted certificate or pre-existing on the device. References: Reputations Assignment for Pre-Existing Files, Reputation Assignment
