In Cisco TMS, the conference control center shows event logs in instance basis. Which two prefixes does the event log use to identify changes to series of single instances? (Choose two.)

The 'Conference' prefix in the TMS CCC event log identifies events or modifications that apply to an entire recurring conference series, distinguishing series-level changes from individual occurrence changes.

The 'Instance' prefix in the TMS CCC event log identifies events or modifications that apply to one specific single occurrence within a recurring conference series.

Error is a severity classification used in general system logging and is not one of the specific TMS Conference Control Center prefixes used to distinguish series versus single-instance conference changes.

Information is a generic log severity level descriptor and is not a TMS CCC event log prefix for identifying whether a change belongs to a conference series or a single instance.

Event is a broad general-purpose logging term and does not serve as one of the specific TMS Conference Control Center prefixes for differentiating series-level from instance-level conference changes.
