Q1. Voice traffic between two campus enterprise networks is growing. The network designers decide to add a second 10-Mb Metro Ethernet service parallel to their original 10-Mb service in order to provide more bandwidth and diversity. The QoS profile will be the same on the new 10-Mb service due to the voice stability on the first Metro Ethernet link. When the second link is added to the OSPF domain, which traffic design consideration would have the most impact on the voice traffic when both links are active? 

A. per-destination IP address basis 

B. per-flow basis 

C. per-packet basis 

D. per-source IP address basis

Q2. 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.

Q3. A company is planning to connect its 30 sites with a VPLS WAN backbone. A router at each site should establish neighborships with all other routers using the OSPF routing protocol. Which three points must be considered regarding DR and BDR when different router platforms are used? (Choose three.) 

A. It is a best practice that the routers with the most powerful hardware should take the role of the DR and BDR. 

B. If the IP OSPF priority is the same for all routers, the highest loopback IP address and router ID will decide which routers will take the DR and BDR role during the selection process. 

C. To select the DR and BDR, the IP OSPF priority must be set to a higher value than the default value at the DR and BDR during the selection process. 

D. To select the DR and BDR, the IP OSPF priority must be set to a lower value than the default value at the DR and BDR during the selection process. 

E. The role for the DR and BDR will be selected when a new OSPF router comes up. 

F. To force two routers to become a DR and a BDR, the IP OSPF priority can be set to zero at all other OSPF routers.

Q4. You are designing a network using multipoint GRE tunnels and need to be able to detect when connectivity between the GRE tunnel endpoints is broken. Which statement is true about configuring keepalives for multipoint GRE tunnels? 

A. The keepalive timer values on the routers must have the same value. 

B. Both routers must support GRE tunnel keepalives. 

C. No configuration is required to detect when connectivity is broken between the GRE tunnel endpoints. 

D. GRE tunnel keepalives will not detect when connectivity is broken between the GRE tunnel endpoints.

Q5. You have been hired by a startup company to provide optical services using MPLS-TP. Which three options describe reasons to use the MPLS-TP standard in your design? (Choose three.) 

A. MPLS-TP is a newer packet transport technology that replaces SONET/SDH. 

B. MPLS-TP includes extensions to native MPLS OAM for fault detection, monitoring, and propagation. 

C. MPLS-TP requires a routing protocol. 

D. MPLS-TP uses an IANA assigned label 13 for OAM. 

E. MPLS-TP uses Ethernet Y.1731 OAM.

Q6. You are designing a network that will run EIGRP over a Metro Ethernet service that does not employ a link-loss technology. What will be the impact on convergence if there is a break in the end-to-end Layer 2 connectivity within the service provider network? 

A. The routers will immediately lose their adjacencies and converge. 

B. The routing protocol will not converge until the hold timers have expired. 

C. The switch ports connected to the router will go down and the routers will immediately converge. 

D. The VLAN on the switches will go inactive, the ports associated on the switch will go down, and the routers will immediately converge.

Q7. A metro service provider is planning Resilient Ethernet Protocol for his backbone. Which two aspects must be considered before the network design is finalized? (Choose two.) 

A. Two Resilient Ethernet Protocol segments can be connected redundantly at two points. One connection will be blocked, using the Spanning Tree Protocol defined in IEEE 802.1D. 

B. UniDirectional Link Detection Protocol can be enabled on Resilient Ethernet Protocol interfaces to detect unidirectional failures. 

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

D. A Resilient Ethernet Protocol segment is limited to a maximum of seven devices. 

E. VLAN load balancing for optimal bandwidth usage is supported in any Resilient Ethernet Protocol segment.

A. Latency: 110 ms Packet loss: 1% Jitter: 40 ms 

B. Latency: 130 ms Packet loss: 0.5% Jitter: 30 ms 

C. Latency: 150 ms Packet loss: 1.25% Jitter: 20 ms 

D. Latency: 170 ms Packet loss: 0.75% Jitter: 10 ms

Q9. Refer to the exhibit. 

An enterprise is migrating its single-area OSPF network from a Frame Relay WAN service to an MPLS L3VPN service. Frame Relay will remain in only a few sites that require increased resiliency via two different WAN connections. 

Which feature could be used in the ?MPLS VPN service provider network to support the design requirement by ensuring that during normal operation, intersite traffic will only use the MPLS VPN service and not the old Frame Relay service? 

A. virtual links 

B. sham links 

C. multiple stub areas 

D. super backbone

B. proposal-agreement handshake 

C. loop guard 

D. UplinkFast
