QUESTION 691

Refer to the exhibit. Voice traffic is marked “precedence 5.” How much bandwidth is allocated for voice traffic during periods of congestion?

 

clip_image002

 

A.

a minimum of 48 kb/s

B.

a maximum of 48 kb/s

C.

a minimum of 48% of the available bandwidth

D.

a maximum of 48% of the available bandwidth

 

Correct Answer: B

 

 

 

 

 

QUESTION 692

Refer to the exhibit. Which of these is applied to the Bearer class?

 

clip_image004

 

A.

wred

B.

traffic shaping

C.

packet marking

D.

packet classification

E.

FIFO queuing within the class

 

Correct Answer: E

 

 

QUESTION 693

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 Answer: AC

QUESTION 694

Refer to the exhibit. What is the overall type of queuing being used on the outgoing data for interface Ethernet0/1?

clip_image006

 

A.

LLQ

B.

FIFO

C.

CBWFQ

D.

priority queuing

E.

weighted fair queuing

 

Correct Answer: A

 

 

QUESTION 695

A.

Guaranteed PHB

B.

Class-Selector PHB

C.

Reserved Forwarding PHB

D.

Discard Eligible PHB

E.

Priority PHB

 

Correct Answer: B

 

 

QUESTION 696

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 OoS 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 Answer: D

 

 

QUESTION 697

Which two statement about VPLS are true? (Choose two.)

 

A.

Split horizon is used on PE devices to prevent loops.

B.

Spanning tree is extended from CE to CE.

C.

IP is used to switch Ethernet frames between sites.

D.

PE routers dynamically associate to peers.

E.

VPLS extends a Layer 2 broadcast domain.

 

Correct Answer: AE

 

 

QUESTION 698

Which two statements about redistribution are true? (Choose two.)

 

A.

When BGP traffic is redistributed into OSPF, the metric is set to 1 unless the metric is defined.

B.

When EIGRP routes on a CE are redistributed through a PE into BGP, the Cost Community POI is set automatically.

C.

When OSPF traffic is redistributed into BGP, internal and external routes are redistributed.

D.

When BGP traffic is redistributed into OSPF, eBGP and iBGP routes are advertised.

E.

iBGP routes automatically redistribute into the IGP if the routes are in the routing table.

F.

When EIGRP traffic is redistributed into BGP, a default metric is required.

 

Correct Answer: AB

 

 

 

 

 

 

 

QUESTION 699

Refer to the exhibit. The two standalone chassis are unable to convert into a VSS. What can you do to correct the problem?

 

clip_image008

 

A.

Set a different port channel number on each chassis.

B.

Set a different virtual domain ID on each chassis.

C.

Set the redundancy mode to rpr on both chassis.

D.

Add two ports to the port channel group.

 

Correct Answer: A

 

 

QUESTION 700

Which three address family types does EIGRP support? (Choose three.)

 

A.

IPv4 unicast

B.

IPv4 multicast

C.

IPv6 unicast

D.

IPv6 multicast

E.

IPv4 anycast

F.

IPv6 anycast

 

Correct Answer: ABC
