Q4. You are performing a BGP design review for a service provider that offers MPLS-based services to their end customers. The network is comprised of several PE routers that run iBGP with a pair of route reflectors for all BGP address families. Which two options about the use of Constrained Route Distribution for BGP/MPLS VPNs are true? (Choose two.) 

A. This feature must be enabled on all devices in the network at the same time. 

B. The RR must advertise the default route target filter toward the PE routers. 

C. The RRs do not need to advertise any route target filter toward the PE routers. 

D. Both PE and RR routers must support this feature.

Q6. What is a design aspect regarding multicast transport for MPLS Layer 3 VPNs using the Rosen Draft implementation? 

A. LDP is the multicast control plane protocol. 

B. Multicast traffic is forwarded over GRE tunnels. 

C. Multicast traffic is forwarded over LDP or RSVP signaled LSPs. 

D. Using the MDT SAFI in BGP ensures that PIM can be disabled in the core.

Q8. The Customer X network consists of an MPLS core, IS-IS running as IGP, a pair of BGP route reflectors for route propagation, and a few dozens of MPLS-TE tunnels for specific tactical traffic engineering requirements. The customer engineering department has some questions about the use of the Overload Bit in the IS-IS networks and how it could be used to improve their current network design. Which three options about the Overload Bit are true? (Choose three.) 

A. It is not recommended on BGP route reflectors. 

B. It only affects the use of the respective node as a transit node, and networks advertised within the LSPs of the node are still reachable. 

C. It can be set on a router during the startup process for a fixed period of time. 

D. It forces the midpoint MPLS-TE node to reoptimize the primary tunnels going through the OL node. 

E. It can be set on a router until other interacting protocols have signaled convergence.

Q9. Your company requires two diverse multihop External Border Gateway Protocol peerings to a partner network. Which two methods would you use to improve lost peer detection? (Choose two.) 

A. Use Bidirectional Forwarding Detection for the peers. 

B. Use Selective Address Tracking and match the peers. 

C. Use subsecond keepalives for the peers. 

D. Use subsecond hold timers for the peers. 

E. Use Fast Peering Session Deactivation for the peers. 

F. Use subsecond minimum route advertisement Interval timers for the peers.

Q10. 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. 

How would you design your solution to map the DSCP value properly so that the traffic is assigned to the respective queues in the Service Provider XYZ MPLS core network? 

A. Classify traffic according to DSCP value into appropriate P router queues. 

B. Map the appropriate DSCP value into the EXP field based on the number of queues in the MPLS P routers. 

C. Map the appropriate DSCP value into the EXP field based on the number of queues in the MPLS PE routers. 

D. Based on the DSCP value, traffic is mapped automatically into appropriate queues in the MPLS CE routers.
