QUESTION: 33

Company XYZ is running OSPF in their network. They have merged with another company that is running EIGRP as the routing protocol. Company XYZ now needs the two domains to talk to each other with redundancy, while maintaining a loop free environment. The solution must scale when new networks are added into the network in the near future. Which technology can be used to meet these requirements?

single point route-redistribution with route filtering using route tags
multipoint route-redistribution with route filtering using ACLs
multipoint route-redistribution with route filtering using route tags
single point route-redistribution with route filtering using ACLs

QUESTION: 34

What are two common approaches to analyzing and designing networks? (Choose two.)

three-tier approach
top-down approach
high-low security approach
bottom-up approach
left-right approach

Answer(s): B,D

Explanation:

B) Top-down approach: This approach involves starting with the high-level requirements and goals of the network design and then gradually breaking them down into more detailed components. It focuses on understanding the overall business needs and objectives before diving into the technical details. This approach helps ensure that the network design aligns with the organization's goals and provides a holistic view of the network requirements.

D) Bottom-up approach: This approach involves starting with the individual components and gradually building up the network design from the ground up. It focuses on the specific technical details, such as network protocols, hardware, and configurations, and then combines them to form a complete network design. This approach is more focused on the technical aspects and can be useful for understanding the specific implementation details of the network.

QUESTION: 35

Refer to the exhibit.

OSPF is running as the IGP to provide reachability to all AS100 networks. R3 and R4 are the current ABRs at the boundary of OSPF Area0 and Area1. Now BGP must be deployed within AS100 because it will be receiving Internet routes from its eBGP peers (the service provider) connected to R1 andR2. What is an optimal solution for this deployment to configure BGP relationships and redistribute BGP learned routes into OSPF?

R5 should be configured as a route reflector for R1, R2, R3 and R4. BGP routes must be redistributed at R1 and R2 into OSPF.
Confederation should be set up with R1, R5, and R3 in one sub AS, with R2 and R4 in another, and redistribution at R1 and R2.
R1, R2, R3 and R4 must be set up with a neighbor relationship with R5 only. R5 must not be a route reflector.
A full mesh should be deployed between all the routers with mutual redistribution to take place at R1 and R2.

QUESTION: 36

A multicast network is using Bidirectional PIM. Which two combined actions achieve high availability so that two RPs within the same network can act in a redundant manner? (Choose two.)

Advertise the two RP addresses in the routing protocol.
Use two phantom RP addresses.
Manipulate the multicast routing table by creating static mroutes to the two RPs.
Control routing to the two RPs through a longest match prefix.
Use Anycast RP based on MSDP peering between the two RPs.
Manipulate the administrative distance of the unicast routes to the two RPs.
