400-007 practice questions, page 7 of 14, with answer review and explanations.

Question 31

What is the most important operational driver in building a resilient and secure modular network design?

  1. Minimize app downtime
  2. Reduce the frequency of failures requiring human intervention
  3. Increase time spent on developing new features
  4. Dependencies on hardware or software that is difficult to scale

Question 32

Refer to the exhibit. For Company XYZ, Bangkok is using ECMP to reach the 172.20.2.0/24 network. The company wants a design that would allow them to forward traffic from 172.16.2.0/24 toward 172.20.2.0/24 via the Singapore router as the preferred route. The rest of the traffic should continue to use ECMP. Which technology fulfills this design requirement?

  1. policy-based routing
  2. unequal-cost load balancing using variance
  3. route summarization
  4. LFA

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?

  1. single point route-redistribution with route filtering using route tags
  2. multipoint route-redistribution with route filtering using ACLs
  3. multipoint route-redistribution with route filtering using route tags
  4. single point route-redistribution with route filtering using ACLs

Question 34

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

  1. three-tier approach
  2. top-down approach
  3. high-low security approach
  4. bottom-up approach
  5. left-right approach

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 and R2. What is an optimal solution for this deployment to configure BGP relationships and redistribute BGP learned routes into OSPF?

  1. 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.
  2. 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.
  3. R1, R2, R3 and R4 must be set up with a neighbor relationship with R5 only. R5 must not be a route reflector.
  4. A full mesh should be deployed between all the routers with mutual redistribution to take place at R1 and R2.
