Which of the following will happen on a CTS when packet loss exceeds 10 percent for 10 seconds during a
call? (Choose three.)
A.
An alarm is written to syslog.
B.
An SNMP trap is generated.
C.
An onscreen message appears for 15 seconds.
D.
The video quality is reduced.
E.

Explanation:
When packet loss exceeds 10 percent for 10 seconds during a call on a Cisco TelePresence System (CTS),
the CTS will write an alarm to syslog, generate a Simple Network Management Protocol (SNMP) trap, and
display an onscreen message for 15 seconds. Alarms and SNMP traps will continue to be generated for the
next five minutes without any corresponding onscreen messages.
The video quality will not be reduced. A CTS will not reduce video quality until it experiences 10percent packet
loss for 60 seconds. Video quality is reduced by lowering motion handling; resolution is not affected.The call will not be dropped. A CTS will not drop a call until it experiences 100percent packet loss for 30
seconds or 10percent packet loss for 180 seconds.Cisco: Release Notes for Cisco TelePresence System Software Release 1.7: Cisco Telepresence Smart Media
