Which of the following are found in the audit log on a Cisco TelePresence MCU?

A.
H.323 messages and SIP messages

B.
call detail records

C.
configuration changes

D.
errors, warnings, and informational messages

Explanation:
Configuration changes are found in the audit log on a Cisco TelePresence multipoint control unit (MCU). A
Cisco TelePresence MCU stores the last 100,000 audit messages internally or on compact flash if it is
available. However, only 2,000 messages are displayed by using the web interface. You can download the
100,000 stored audit messages to an Extended Markup Language (XML) file.
Errors, warnings, and other informational messages are not found in the audit log on a Cisco TelePresence
MCU; they are found in the event log. The last 2,000 event log messages can be displayed by navigating to
Logs > Event log. You can configure the MCU to send event messages to one or more syslog servers; up to
four syslog servers can be configured.
Call detail records are not found in the audit log on a Cisco TelePresence MCU. Call detail records are found by
navigating to Logs > CDR log. Call detail records can be used for billing and reporting purposes.
H.323 messages and Session Initiation Protocol (SIP) messages are not found in the audit log on a Cisco
TelePresence MCU; they are found in the H.323/SIP log. You can export the log to XML. However, only 10
pages of logged messages can be stored in the H.323/SIP log. By default, the H.323/SIP log is disabled.
