Route Chapter Quiz 1 1. What routing protocol is an enhancement to Cisco Discovery Protocol that advertises the connected IP prefix or prefixes of a stub router via CDP? Routing Information Protocol (RIP) On-Demand Routing (ODR) Intermediate-System to Intermediate-System (IS-IS) None of the answers are correct Open Shortest Path First (EIGRP) Border Gateway Protocol (BGP) Question 1 of 18 2. 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 By default, the load is calculated as an average over a period of five seconds In Cisco IOS software, the interface bandwidth is expressed in Mbps In Cisco IOS software, the interface delay value is in tens of microseconds Only BGP uses the path length in metric calculation In Cisco IOS software, the interface bandwidth is expressed in Kbps The delay refers to the dependability of network links or interfaces By default, the load is calculated as an average over a period of five minutes Question 2 of 18 3. 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. Route Summarization Variable Length Subnet Masks (VLSM) Classless Interdomain Routing (CIDR) Classless Routing Subnet Zero Question 3 of 18 4. Which of the following is NOT a Distance Vector routing protocol characteristic? Incremental Updates Split Horizon Poison Reverse Hold Down Timers Summarization Question 4 of 18 5. In regards to OSPF operation, the Shortest Path First (SPF) algorithm is run BEFORE the database exchange happens. True False Question 5 of 18 6. 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 Incremental Updates Poison Reverse One-dimensional Vector Automatic Summarization 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? No additional configuration is required; they should check Layer 1 and Layer 2 status 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 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 Enable CDP on the spoke router to resolve the issue Question 7 of 18 8. 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 route summary show ip protocols summary show ip protocols show ip route show ip defaults Question 8 of 18 9. 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 timers Convergence is determined by the amount of summarization used Convergence is determined by the routing protocol algorithm Convergence is determined by the routing protocol metrics Convergence is determined by the routing protocol administrative distance Question 9 of 18 10. 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 10 of 18 11. Which of the following is NOT a routing algorithm goal or objective? Optimal Routing Interoperability Ease of Use Flexibility Rapid Convergence Stability Question 11 of 18 12. ODR supports Variable Length Subnet Mask (VLSM) True False Question 12 of 18 13. On Demand Routing has low bandwidth consumption and resource requirements. How many additional bytes are required per prefix when running ODR? 24 bytes 5 bytes 4 bytes 20 bytes 2 bytes 6 bytes Question 13 of 18 14. 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 PATH INIT UNKNOWN LIST TENT Question 14 of 18 15. Which routing protocol can include cost in route metric calculation? BGP IS-IS RIP ODR OSPF EIGRP Question 15 of 18 16. 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 distributed routing system A proprietary routing system A converged routing system A hierarchical routing system A flat routing system 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? Prefix Length Routing Algorithm Administrative Distance Cisco Express Forwarding (CEF) Route Metric Question 17 of 18 18. The default administrative distance value for On Demand Routing (ODR) routes is? 140 115 160 150 170 Question 18 of 18 Loading…
