A.LLQ
B.FIFO
C.CBWFQ
D.priority queuing
E.weighted fair queuing
F.IP RTP priority queuing
Correct Answers: A
22: Which two of these are differences between traffic policing and traffic shaping? (Choose two.)
A.with traffic shaping, a router stores excess traffic in packet buffers until bandwidth is available again
B.with policing you can tune the buffer usage for traffic exceeding the specified CIR
C.with shaping you can tune the buffer usage for traffic exceeding the specified CIR
D.shaping should only be applied for ingress traffic, policing only for egress
E.policing uses a token bucket algorithm, shaping uses an SPD algorithm
Correct Answers: A C
23: Which of these is a valid differentiated services PHB?
A.Guaranteed PHB
B.Class-Selector PHB
C.Reserved Forwarding PHB
D.Discard Eligible PHB
E.Priority PHB
Correct Answers: B
24: 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?
A.mark VOIP traffic with IP precedence 6 and configure only ‘fair-queue’ on the links
B.configure the scheduler allocate 3000 1000 command to allow the QoS code to have enough CPU cycles
C.enable class-based traffic shaping on the VoIP traffic class
D.enable Layer 2 fragmentation and interleaving on the links
E.enable Frame Relay on the links and send voice and data on different Frame Relay PVCs
Correct Answers: D
25: 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?
A.data marked with DSCP AF21, VOIP marked with DSCP EF
B.data marked with DSCP AF51, VOIP marked with DSCP EF
C.data marked with the DE-bit, VOIP marked with the CLP-bit
D.data marked with DSCP EF, VOIP marked with DSCP AF31
E.data marked with IP precedence 5, VOIP marked with DSCP EF
Correct Answers: A
26: 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?
A.The configuration of a hierarchical policy map on a tunnel interface is not supported.
B.Class 5555 and class 5554 are both taking up 100% of the bandwidth, leaving nothing for class 1234.
C.The burst size for the traffic shaping is wrongly configured to 15000; this would require an interface capable of sending at 150Mb/s.
D.The burst size for the traffic shaping has been wrongly configured; it should be set as low as possible.
E.The burst size for the traffic shaping has been wrongly configured; it should be set as high as possible.
Correct Answers: D
27: 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
A.The violate-action command should not be configured.
B.The current configuration of the load-interval command on the tunnel interface is preventing proper policing calculations.
C.The burst size is too low.
D.Policing on tunnel interfaces is not supported.
E.The CIR keyword is missing in the policer.
Correct Answers: C
28: Refer to the exhibit. As a network administrator, you have configured a dual-rate, dual-bucket policer in accordance with RFC 2698 on the serial interface of you router, connecting to your provider. The SLA with your provider states that you should only send AF31 (limited to 150 kb/s), AF32 (limited to 50 kb/s)and AF33 (best effort). Your service provider claims you are not conforming to the SLA. Which two things are wrong with this configuration? (Choose two.)
A.The configuration of a service policy on half-duplex Ethernet interfaces is not supported.
B.The class class-default sub-command of the policy-map limit command should be set to the DSCP default.
C.The violate action is wrong.
D.This policer configuration is not implementing RFC 2698 dual-bucket, dual-rate.
E.The policer is configured in the wrong class.
Correct Answers: C E
29: Refer to the exhibit. You have noticed that several users in the network are consuming a great deal of bandwidth for the peer-to-peer application Kazaa2. You would like to limit this traffic, and at the same time provide a guaranteed 100 kb/s bandwidth for one of your servers. After applying the configuration in the exhibit, you notice no change in the bandwidth utilization on the serial link; it is still heavily oversubscribing the interface. What is the cause of this problem?
A.CEF needs to be enabled for NBAR.
B.In class Kazaa2, you should configure a policer instead of a drop command.
C.The server class should have a priority of 100.
D.The bandwidth parameter on serial 0/0 is wrong.
E.Kazaa2 is not a valid protocol.
Correct Answers: A
30: All of these are fundamental building blocks of a differentiated services Traffic Conditioner Block except which one?
A.dropper
B.classifier
C.marker
D.querier
E.meter
F.shaper
Correct Answers: D
