Q7. What are two benefits of using BFD for failure detection in the design of a network?
(Choose two.)
A. BFD can provide failure detection in less than one second.
B. BFD can be used as a generic and consistent failure detection mechanism for EIGRP, IS-IS, and OSPF.
C. BFD eliminates router protocol hello notification.

E. BFD is independent of the network protocol.
Answer: AB
Q8. Which two factors can significantly affect the OSPF network convergence time? (Choose two.)
A. the tuning of OSPF LSA timers
B. the number of OSPF routes
C. the diameter of the OSPF network
D. different processor capabilities of devices
Answer: AD
Q9. A planned EBGP network will use OSPF to reach the EBGP peer addresses. Which of these conditions should be avoided in the design that could otherwise cause the peers to flap continuously?
A. An ACL blocks TCP port 179 in one direction.
B. IP addresses used to peer are also being sent via EBGP.
C. The OSPF area used for peering is nonbackbone (not area 0).
D. The routers are peered by using a default route sent by OSPF.
Answer: B
Q10. You are designing a network that includes IP QoS. Which two architectures could be used to ensure that IP QoS is implemented properly? (Choose two.)
A. Differentiated Services, where the user, with the assistance of the RSVP signaling protocol, reserves the resources end to end before sending the data
B. Integrated Services, where the user, with the assistance of the RSVP signaling protocol, reserves the resources end to end before sending the data
C. Integrated Services, which relies on the information carried within each packet to make resource-allocation decisions at each network node
D. Differentiated Services, which relies on the information carried within each packet to make resource-allocation decisions at each network node
E. Integrated Services, where the user, with the assistance of the DSCP signaling protocol, reserves the resources end to end before sending the data
Answer: BD

Q12. You are the lead network designer hired by Service Provider XYZ to deploy CoS functionality on the core MPLS network (P routers). The goal of the network design is to provide a complete CoS solution to all customers that purchase services such as dedicated Internet access, MPLS L3VPN, and L2VPN (pseudowire). Service Provider XYZ has these design requirements:
The network supports four service queues with equal treatment for delay, jitter, and packet loss.
Queues are numbered 0-3, where 0 is the default queue.
Three queues have one treatment.
One queue has either one or two treatments.
If your design includes eight CoS queues on the Service Provider XYZ MPLS PE router ingress (CE facing) interface, how will customer traffic be classified as it enters the MLS P routers?
A. The eight CoS queues in the MPLS P router are remapped to the eight CoS queues.
B. Traffic is classified on the MPLS PE routers on core facing interface. The DSCP value is mapped into EXP field where multiple EXP settings (2+) will be assigned to a single queue throughout the MPLS P routers.
C. Discard the traffic from the eight CoS queues that does not match the four CoS queues of the MPLS P routers.
D. The 8 CoS queues in the MPLS P router are remapped to four 4 flow-label queues.
Answer: B
