Route Chapter Quiz 1 1. Which of the following is NOT a Distance Vector routing protocol characteristic? Poison Reverse Summarization Split Horizon Hold Down Timers Incremental Updates Question 1 of 18 2. The primary advantage afforded by flat routing systems is their scalability. Flat routing systems also allow for easier changes to the network. True False Question 2 of 18 3. 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? ROOT TENT INIT PATH UNKNOWN LIST 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? Routing Algorithm Prefix Length Route Metric Administrative Distance Cisco Express Forwarding (CEF) Question 4 of 18 5. Which of the following is NOT a routing algorithm goal or objective? Optimal Routing Flexibility Interoperability Stability Ease of Use Rapid Convergence Question 5 of 18 6. 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 metrics Convergence is determined by the amount of summarization used 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 Question 6 of 18 7. Which of the following uses a layered approach wherein routers are placed in logical groupings referred to domains, areas, or autonomous systems? A converged routing system A proprietary routing system A hierarchical routing system A distributed routing system A flat routing system An open routing system Question 7 of 18 8. 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 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 minutes 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 seconds In Cisco IOS software, the interface delay value is in tens of microseconds Question 8 of 18 9. 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) Intermediate-System to Intermediate-System (IS-IS) Open Shortest Path First (EIGRP) On-Demand Routing (ODR) Routing Information Protocol (RIP) None of the answers are correct Question 9 of 18 10. 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. Subnet Zero Route Summarization Classless Routing Classless Interdomain Routing (CIDR) Variable Length Subnet Masks (VLSM) Question 10 of 18 11. Which routing protocol can include cost in route metric calculation? BGP EIGRP IS-IS ODR OSPF RIP Question 11 of 18 12. 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 defaults show ip protocols show ip route Question 12 of 18 13. The default administrative distance value for On Demand Routing (ODR) routes is? 140 150 160 170 115 Question 13 of 18 14. 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 Enable CDP on the spoke router to resolve the issue No additional configuration is required; they should check Layer 1 and Layer 2 status Enable CDP on the hub router to resolve the issue Implement the same configuration on the hub router and enable CDP on both routers Disable CDP on the spoke router and enable CDP on the hub router Question 14 of 18 15. In regards to OSPF operation, the Shortest Path First (SPF) algorithm is run BEFORE the database exchange happens. True False Question 15 of 18 16. On Demand Routing has low bandwidth consumption and resource requirements. How many additional bytes are required per prefix when running ODR? 4 bytes 2 bytes 24 bytes 20 bytes 6 bytes 5 bytes Question 16 of 18 17. 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. Poison Reverse Incremental Updates Topology Table Automatic Summarization One-dimensional Vector Question 17 of 18 18. ODR supports Variable Length Subnet Mask (VLSM) False True Question 18 of 18 Loading…
