   A control room has a server that runs an application to calculate available transfer capability (ATC) for transmission paths. The ATC values are used by operators to schedule transactions. Which BES Reliability Operating Service does this server support?

   • AAvailable transfer capability calculation
   • BInterchange scheduling
   • CTransmission loading relief (TLR)
   • DReal-time monitoring

   A cyber asset is part of a system that monitors transformer temperatures at a generating station. If the monitoring system fails, operators would not receive high-temperature alarms, but the transformers would continue to operate with local protective devices. How should this asset be categorized?

   • AAs a non-BES Cyber Asset because the asset does not perform a BES Reliability Operating Service and its failure does not directly impact reliable operation.
   • BAs a BES Cyber Asset because loss of monitoring could lead to transformer damage and loss of generation.
   • CAs a BES Cyber Asset because it is part of a BES Cyber System that includes protective relays.
   • DAs a BES Cyber Asset because it is associated with a generating station.

   A transmission operator is assessing the impact of a new synchrophasor data concentrator that is part of the wide-area monitoring system. The concentrator collects PMU data from 20 substations and sends it to the RC's situational awareness tool. The RC uses this data to monitor frequency and voltage oscillations. The concentrator is not used for any automatic control. Which of the following is the most appropriate impact rating for the BES Cyber System that includes the concentrator?

   • ALow impact, because the concentrator is only a data aggregation device and does not affect the BES directly.
   • BModerate impact, because the concentrator supports situational awareness, which is a BES Reliability Operating Service, but it does not directly control equipment.
   • CNo impact, because the concentrator is not a protective relay or a control device.
   • DHigh impact, because the loss of the concentrator would impair the RC's ability to monitor wide-area oscillations.
