Refer to the exhibit. A network engineer received a sudden request to prioritize voice over his
Cisco network and he has decided to leverage the AutoQoS feature. Based on the output shown,
which two tasks need to be performed prior to issuing the autoqos voip command in this router?
(Choose two.)
A.
Enable Cisco Express Forwarding.
B.
Enable fast switching.
C.
Delete all policy maps.
D.
Remove service-policy commands from interface serial1/0.
E.
Delete all the currently configured class maps.
Explanation:
AutoQoS VoIP Default Configuration
Before configuring AutoQoS VoIP, you should refer to the IOS 12.3 QoS Configuration Guide,
which lists several considerations and conditions for the right environment for enabling this
feature. For QOS exam purposes, repeating the full list here is not helpful; however, considering a
couple of the most common considerations can help. For instance
AutoQoS VoIP requires that CEF be enabled first.
AutoQoS VoIP cannot be used if the interface already has a service-policy command configured.
Because AutoQoS VoIP relies on the bandwidth settings configured in the bandwidth command,
the routers should be configured with correct bandwidth settings on each interface before enabling
AutoQoS VoIP. (If you change the bandwidth after enabling AutoQoS VoIP, AutoQoS VoIP does
not react and does not change the QoS configuration.)
Supports only point-to-point subinterfaces on Frame Relay interfaces.
Supports HDLC, PPP, Frame Relay, and ATM data link protocols.http://www.ciscopress.com/articles/article.asp?p=358548&seqNum=6
