Route Chapter Quiz 1 1. Which of the following is NOT a routing algorithm goal or objective? Rapid Convergence Optimal Routing Stability Interoperability Flexibility Ease of Use Question 1 of 18 2. 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 administrative distance Convergence is determined by the routing protocol timers Convergence is determined by the routing protocol algorithm Convergence is determined by the amount of summarization used Convergence is determined by the routing protocol metrics Question 2 of 18 3. Which of the following is NOT a Distance Vector routing protocol characteristic? Poison Reverse Split Horizon Incremental Updates Summarization Hold Down Timers Question 3 of 18 4. What routing protocol is an enhancement to Cisco Discovery Protocol that advertises the connected IP prefix or prefixes of a stub router via CDP? Border Gateway Protocol (BGP) Open Shortest Path First (EIGRP) Routing Information Protocol (RIP) On-Demand Routing (ODR) Intermediate-System to Intermediate-System (IS-IS) None of the answers are correct Question 4 of 18 5. Which of the following commands can be used to validate the default administrative distance for routes learned by all routing protocols? Select the BEST answer. show ip protocols summary show ip route summary show ip protocols show ip route show ip defaults Question 5 of 18 6. 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 Routing Route Summarization Classless Interdomain Routing (CIDR) Subnet Zero Variable Length Subnet Masks (VLSM) Question 6 of 18 7. 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? Implement this configuration on the hub router instead and only enable CDP on the spoke router 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 Enable CDP on the hub router to resolve the issue Implement the same configuration on the hub router and enable CDP on both routers Question 7 of 18 8. Which of the following uses a layered approach wherein routers are placed in logical groupings referred to domains, areas, or autonomous systems? A distributed routing system A hierarchical routing system A flat routing system A converged routing system A proprietary routing system An open routing system Question 8 of 18 9. 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. Topology Table Automatic Summarization One-dimensional Vector Poison Reverse Incremental Updates Question 9 of 18 10. In regards to OSPF operation, the Shortest Path First (SPF) algorithm is run BEFORE the database exchange happens. True False Question 10 of 18 11. The default administrative distance value for On Demand Routing (ODR) routes is? 140 115 170 160 150 Question 11 of 18 12. Which routing protocol can include cost in route metric calculation? OSPF RIP BGP IS-IS ODR EIGRP Question 12 of 18 13. ODR supports Variable Length Subnet Mask (VLSM) True False Question 13 of 18 14. Which of the following statements about routing protocol metrics are TRUE? Select THREE answers. In Cisco IOS software, the interface delay value is in microseconds The delay refers to the dependability of network links or interfaces In Cisco IOS software, the interface bandwidth is expressed in Mbps By default, the load is calculated as an average over a period of five minutes In Cisco IOS software, the interface bandwidth is expressed in Kbps Only BGP uses the path length in metric calculation By default, the load is calculated as an average over a period of five seconds In Cisco IOS software, the interface delay value is in tens of microseconds Question 14 of 18 15. 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 15 of 18 16. 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? LIST UNKNOWN ROOT INIT PATH TENT Question 16 of 18 17. 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? Routing Algorithm Cisco Express Forwarding (CEF) Administrative Distance Route Metric Prefix Length Question 17 of 18 18. On Demand Routing has low bandwidth consumption and resource requirements. How many additional bytes are required per prefix when running ODR? 6 bytes 5 bytes 20 bytes 24 bytes 2 bytes 4 bytes Question 18 of 18 Loading…
