Q2. Refer to the exhibit. 

This diagram depicts the design of a small network that will run EIGRP on R1 and R2, and EIGRP Stub on R3. In which two ways will this network be impacted if there is link instability between R1 and R2? (Choose two.) 

A. R1 will have routes in its routing table that originate from R2 and R3. 

B. R3 will have routes in its routing table that originate from R1 and R2. 

C. R2 will have routes in its routing table that originate from R1 and R3. 

D. R3 will be transit for traffic between R1 and R2. 

E. R3 will not be transit for traffic between R1 and R2.

Q3. Refer to the exhibit. 

A customer runs OSPF with Area 5 between its aggregation router and an internal router. When a network change occurs in the backbone, Area 5 starts having connectivity issues due to the SPF algorithm recalculating an abnormal number of times in Area 5. You are tasked to redesign this network to increase resiliency on the customer network with the caveat that Router B does not support the stub area. How can you accomplish this task? 

A. Set Area 5 to stubby at the ABR anyway. 

B. Increase the bandwidth on the connection between Router A and Router B. 

C. Turn on LSA throttling on all devices in Area 5. 

D. Implement LSA filtering on the ABR, allowing summary routes and preventing more specific routes into Area 5. 

E. Create a virtual link to Area 0 from Router B to the ABR.

Q4. Which two OSPF design considerations should you implement to support the eventual growth of a network, so that CPU and memory are unaffected by the size and complexity of the link-state database in a large service provider network? (Choose two.) 

A. Turn on route dampening. 

B. Create network summaries. 

C. Turn on the Incremental SPF feature. 

D. Add more memory. 

E. Turn on packet pacing. 

F. Add redundancy between critical locations.

Q5. 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.

Q6. Refer to the exhibit. 

A service provider would like to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2. In which two of these ways can you design this solution? (Choose two.) 

A. Enable Y.1731 Connectivity Fault Management on the SP switches. 

B. E-LMI PDUs must be forwarded over VPLS. 

C. Cisco Discovery Protocol PDUs must be forwarded over the VPLS. 

D. Use upward maintenance endpoints on the SP switches. 

E. Enable IEEE 802.1ag Connectivity Fault Management on the SP switches.

Q7. Which two options are characteristics of firewall transparent mode operations in a firewall solution design? (Choose two.) 

A. The firewall acts like a router hop in the network. 

B. OSPF adjacencies can be established through the firewall. 

C. Changes in the existing IP addressing and subnets are required. 

D. Multicast traffic can traverse the firewall. 

E. The firewall can participate actively on spanning tree.

Q8. Which two design aspects should a metro service provider consider when planning to deploy REP for his backbone? (Choose two.) 

A. Two REP segments can be connected redundantly at two points, one connection will be blocked as per the STP defined in IEEE 802.1d. 

B. UDLD can be enabled on REP interfaces to detect unidirectional failures. 

C. The guaranteed convergence recovery time is less than 50 ms for the local segment. 

D. A REP segment is limited to a maximum of seven devices. 

E. VLAN load balancing for optimal bandwidth usage is supported in any REP segment.

Q9. 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.

Q10. You have created a network design that has two point-to-point Metro Ethernet circuits extending a single production VLAN between two data centers. Under normal circumstances, one circuit will carry traffic and spanning tree will block the other. If the company wants you to make use of both circuits to carry production traffic, which two technologies and features will you investigate to integrate into your network design? (Choose two.) 

A. EtherChannel 

B. MST 

C. Multichassis EtherChannel 

D. PVST+
