Which routing solution is the most scalable to connect the branches to the HQ and to connect the branches together over the internet using DMVPN?

A. EIGRP

B. EIGRP with the branch routers setup as stubs

C. OSPF with each branch router as an ABR

D. IS-IS L2 in all locations

E. OSPF Area 0 in all locations

You are presented with requirements to design a development, testing and production environments. These environment should communicate with each other, yet they should be kept as separate failure domains. Which routing protocol should be configured on the links between the networks to support the design requirements?

A. OSPF

B. EIGRP

C. IS-IS

D. BGP

Refer to the exhibit.

This new OSPF network has four areas, but the hub-and-spoke area experiences frequent flapping. In order to fix this design failure, which two mechanisms can you use to isolate the data center area from the hub-and-spoke area without losing Ip connectivity? (Choose two)

A. Use OSPF distribute-list filtering on router A

B. Deploy a prefix summarization on router D

C. Make the data center area a NSSA

D. Make the data center area totally stub

E. Convert the data center area to EIGRP protocol

When is it required to leak routes into an IS-IS Level 1 area?

A. when equal cost load balancing is required between the backbone and non-backbone areas

B. when unequal cost load balancing is required between the backbone and non-backbone areas

C. when MPLS L3VPN PE devices are configured in the Level 1 areas

D. when a multicast RP is configured in the non-backbone area

You are implementing a one-to-many multicast solution for a large service provider network. Which technology offers optimal routing of multicast traffic?

A. PIM sparse mode

B. PIM SSM

C. Anycast RP

D. MSDP

E. Bidirectional PIM.

Refer to the exhibit.

Transit traffic in this large enterprise campus network passes the eBGP core. Per security policy, traffic coming from AS 65444 destined for AS 65466 and vice-versa must pass through AS 65400. An audit discovers that traffic between 65444 and 65466 did not pass through 65400, instead it is communicating directly. How must you design BGP to ensure that the traffic from AS 65444 destined for AS 65466 passes through AS65400 on this broadcast network?

A. Apply an ACL on AS 65466 to drop the direct traffic between AS 65444 and AS 65466

B. Apply AS-path prepending on AS 65466 and AS 65444

C. Apply next-hop self on both BGP neighbors on AS 65400

D. Apply the MED attribute on the BGP session for AS 65444

You are hired to assist an enterprise customer to design their global WAN network. A protected DWDM circuit with disjoint fiber routes and guaranteed restoration times is ordered to connect two hub sites. Which option is a BFD design consideration in relation to protected DWDM?

A. BFD failure detection must be faster than DWDM restoration time

B. The BFD hello timer must match the DWDM circuit restoration time

C. BFD failure detection must be longer than DWDM restoration time

D. BFD cannot be used with protected DWDM

A Mobile Service Provider would like to design and deploy an Ethernet service which has similar physical link failover/failback characteristics on the active/backup links as the APS/MSP SONET properties. Which Layer 2 service addresses should be considered to address this design feature?

A. Port-Channel

B. MLPPP

C. Flex Link

D. Ethernet Pseudowire

You are designing dual-homed active/active ISP connections from an enterprise customer for internet services, and you have recommended BGP between the customer and ISP. When three security mechanisms do you enable to secure the connection? (Choose three)

A. uRPF is strict mode

B. remote triggered black holes

C. IDS

D. GTSM

E. Routing protocol authentication

F. uRPF in loose mode

In an Ethernet link containing five routers with OSPF network interface type configured as broadcast, how many OSPF adjacencies are established on this Ethernet link?

A. 7

B. 5

C. 10

D. 20

E. 6
