CCNA Sample Questions

640-801

The Building Scalable Cisco Certification exam is a qualifying exam for the CCNA certifications. The exam will certify that the successful candidate has important knowledge and skills necessary to use advanced IP addressing and routing in implementing scalability for Cisco routers connected to LANs and WANs. The exam covers topics on Advanced IP Addressing, Routing Principles, Configuring the EIGRP, Configuring the Open Shortest Path First Protocol, Configuring IS-IS, Manipulating Routing Updates, and configuring basic BGP.

We provide CCNA sample questions that help test your preparedness for taking the actual cisco certification exam. CCNA 640-801 sample questions help in consolidating your concepts, preparation and also as exam cram. Each CCNA sample question is based on respective vendors published exam objectives and designed to help attain cisco certification.

5. Two routers Rtr1 and Rtr2 are both configured with RIP only. What will be the result when Rtr1 receives a routing update that contains a higher cost path to a network already in its routing table?
   
   
   
   1. The update information will replace the existing routing table entry.
      
   2. The update information will be added to the existing routing table.
      
   3. The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergence.
      
   4. The update will be ignored and no further action will be taken.
      
   
   

   Answer :E
