The correct answers are A, C, and D because camera upgrade operations in the intelligent vision environment include license-related activation , algorithm package upgrade , and software version upgrade , but do not include simply resetting a camera. The material explains that apps on the intelligent camera platform can be “installed, activated, upgraded, and uninstalled online” and that the App Manager “installs, activates, monitors, and upgrades intelligent apps” . It also states that end users can install RPM software packages on SDCs and that “users need to purchase a license file … and load the license file on the SDC” for chargeable apps. This directly supports license loading and algorithm package upgrade as part of operational upgrade handling.
In addition, software version upgrade is a standard maintenance activity, and the material explicitly references upgrade behavior, including “During upgrade within the power module” and version-upgrade scenarios that require recalibration after software changes. Resetting a camera, however, is a recovery or configuration action, not an upgrade action. Therefore, the valid upgrade operations are A, C, and D .
