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