Which of the following is NOT a routing algorithm goal or objective? Optimal Routing Ease of Use Stability Rapid Convergence Interoperability Flexibility Question 3 of 18 4. What do Cisco routers use to determine which of the routes placed into the routing table should be used to forward traffic to a destination network or node? Administrative Distance Prefix Length Route Metric Cisco Express Forwarding (CEF) Routing Algorithm Question 4 of 18 5. Which of the following is NOT a Distance Vector routing protocol characteristic? Summarization Hold Down Timers Incremental Updates Split Horizon Poison Reverse Question 5 of 18 6. On Demand Routing has low bandwidth consumption and resource requirements. How many additional bytes are required per prefix when running ODR? 5 bytes 4 bytes 24 bytes 2 bytes 20 bytes 6 bytes Question 6 of 18 7. The default administrative distance value for On Demand Routing (ODR) routes is? 160 140 150 115 170 Question 7 of 18 8. The SPF algorithm creates a shortest-path tree to all hosts in an area or in the network backbone, with the router that is performing the calculation at the root of that tree. What THREE sets are used in the SPF calculation? INIT ROOT TENT PATH UNKNOWN LIST Question 8 of 18 9. The primary advantage afforded by flat routing systems is their scalability. Flat routing systems also allow for easier changes to the network. False True Question 9 of 18 10. Which characteristic possed by advanced distance routing protocols (EIGRP) is most similar to one possed by Link State routing protocols (OSPF)? Select the BEST answer. Automatic Summarization Poison Reverse One-dimensional Vector Topology Table Incremental Updates Question 10 of 18 11. A co-worker of yours is implementing ODR on a spoke router, which is connected to the hub router across a Frame Relay WAN. They have configured the spoke router as follows: Spoke#conf t Enter configuration commands, one per line. End with CNTL/Z. Spoke(config)#router odr Spoke(config-router)#exit Spoke(config)#exit Following this configuration, your co-worker asks for your help as the spoke router is not receiving any routing information from the hub router. What would you tell your co-worker to do? Enable CDP on the hub router to resolve the issue Implement this configuration on the hub router instead and only enable CDP on the spoke router Implement the same configuration on the hub router and enable CDP on both routers No additional configuration is required; they should check Layer 1 and Layer 2 status Disable CDP on the spoke router and enable CDP on the hub router Enable CDP on the spoke router to resolve the issue Question 11 of 18 12. Which of the following techniques could be used to reduce the amount of information that routers must process, which allows for faster convergence within the network? Select the BEST answer. Classless Interdomain Routing (CIDR) Subnet Zero Classless Routing Variable Length Subnet Masks (VLSM) Route Summarization Question 12 of 18 13. Consider the following statement: Network convergence occurs when all routers in the network have the same view and agree on optimal routes Based on the statement above, select the BEST answer. Convergence is determined by the routing protocol algorithm Convergence is determined by the routing protocol administrative distance Convergence is determined by the routing protocol metrics Convergence is determined by the amount of summarization used Convergence is determined by the routing protocol timers Question 13 of 18 14. Which routing protocol can include cost in route metric calculation? IS-IS EIGRP RIP ODR OSPF BGP Question 14 of 18 15. ODR supports Variable Length Subnet Mask (VLSM) False True Question 15 of 18 16. In regards to OSPF operation, the Shortest Path First (SPF) algorithm is run BEFORE the database exchange happens. True False Question 16 of 18 17. What routing protocol is an enhancement to Cisco Discovery Protocol that advertises the connected IP prefix or prefixes of a stub router via CDP? None of the answers are correct Routing Information Protocol (RIP) Intermediate-System to Intermediate-System (IS-IS) Border Gateway Protocol (BGP) Open Shortest Path First (EIGRP) On-Demand Routing (ODR) Question 17 of 18 18. Which of the following uses a layered approach wherein routers are placed in logical groupings referred to domains, areas, or autonomous systems? An open routing system A converged routing system A distributed routing system A hierarchical routing system A proprietary routing system A flat routing system Question 18 of 18 Loading…
