An expanding company is deploying leased lines between its main site and two remote sites. The
bandwidth of the leased lines is 128kb/s each, terminated on different serial interfaces on the main
router. These links are used for combined VOIP and data traffic. The network administrator has
implemented a VOIP solution to reduce costs, and has therefore reserved sufficient bandwidth in a
low latency queue on each interface for the VOIP traffic. Users now complain about bad voice
quality although no drops are observed in the low latency queue. What action will likely fix this
problem?

You are the network administrator of an enterprise with a main site and multiple remote sites. Your
network carries both VOIP and data traffic. You agree with your service provider to classify VOIP
and data traffic according to the different service RFCs. How can your data and VOIP traffic be
marked?

Refer to the exhibit. When applying this hierarchical policy map on the on the tunnel1 interface,
you measure high jitter for traffic going through class 1234. What is the most likely cause of this
jitter?

Refer to the exhibit. When applying this policy map on the tunnel1 interface, you see packet loss
for the TCP class starting at around 100000 b/s, instead of the configured 150000 b/s. What is the
most likely cause of the discrepancy?

NBAR supports all of these with the exception of which one?

Modified deficit round robin supports which of these functionalities?

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.)

What is an important consideration that should be taken into account when configuring shaped
round robin?

Refer to the exhibit. Based on the configuration shown, which queuing mechanism has been
configured on interface serial.1/0?

Which two benefits are of applying WRED? (Choose two.)
