   A distribution provider is evaluating a distributed energy resource (DER) that is connected to the distribution system but is capable of exporting power to the BES. The DER has a controller that can regulate voltage and frequency at the point of interconnection. The distribution provider has not yet determined if the DER is part of the BES. Which of the following is the most appropriate first step in determining if the controller is a BES Cyber Asset?

   • ACategorize the controller as a BES Cyber Asset because it can regulate voltage and frequency.
   • BDetermine if the DER is part of the BES by applying the Attachment 1 criteria, including the 60/75 MW threshold.
   • CCategorize the controller as a BES Cyber Asset only if it is connected to the distribution provider's SCADA system.
   • DCategorize the controller as a non-BES Cyber Asset because it is on the distribution system.

   A reliability engineer at a generation owner is inventorying cyber assets at a 500 MW combined-cycle plant. The plant's DCS includes a historian server that collects operational data from the unit's control system. The historian is not used for real-time control, but it provides data that operators use to make manual decisions about unit dispatch. The plant's owner has determined that the DCS is a BES Cyber System under the Moderate impact rating. Which of the following best describes whether the historian server should be categorized as a BES Cyber Asset?

   • AYes, but only if the historian is directly connected to the plant's wide-area network.
   • BNo, because it is not used for real-time control and therefore does not have an operational effect on the BES.
   • CNo, because the historian is not a protective or control device and thus falls outside the Attachment 1 criteria.
   • DYes, because it is part of the DCS, which is a BES Cyber System, and it is associated with the reliable operation of the BES.

   When assessing the operational impact of a Cyber Asset, which of the following best describes the 'operational effects' that must be considered?

   • AThe financial cost of replacing the asset if it fails.
   • BThe impact on the reliable operation of the Bulk Electric System if the asset is compromised.
   • CThe age and maintenance history of the asset.
   • DThe physical security measures in place at the asset's location.
