Question: 1 Which two statements are true about IS-IS routing?(Choose two.) A. Based on the default timers, OSPF detects a failure faster than IS-IS does. B. OSPF default timers permit more tuning than IS-IS does. C. IS-IS is more efficient than OSPF in the use of CPU resources. D. OSPF is more scalable than IS-IS because of its ability to identify normal, stub, and NSSA

The command metric weights 0 0 1 0 0 has been added to the EIGRP process so that only the delay metric is used in the path calculations. Which router will R1 select as the successor and feasible successor for Network A?

A. R4 becomes the successor for Network A and will be placed in the routing table. R2 becomes the feasible successor for Network A. B. R4 becomes the successor for Network A and will be included in the routing table. No feasible successor will be selected as the advertised distance from R2 is higher than the feasible

distance. C. R2 becomes the successor and will be placed in the routing table. R4 becomes the easible successor for Network A. D. R2 becomes the successor and will be placed in the routing table. No feasible successor will

be selected as the reported distance from R4 is lower than the feasible distance. Answer: B

ISATAP tunnel Answer: C Question: 6 If a metric is not specified for routes that are redistributed into OSPF, the default metric that is assigned to the routes is 20, except for redistributed BGP routes. What is the metric that is assigned to redistributed BGP routes? A. 200 B. 0 C. 1 D. 10 Answer: C Question: 7 During a redistribution of routes from OSPF into EIGRP, an administrator notices that none of the OSPF routes are showing in EIGRP. What are two possible causes? (Choose two.) A. incorrect distribute lists have been configured B. missing ip classless command C. CEF not enabled D. no default metric configured for EIGRP Answer: A, D

(IPv6 OSPF Virtual Link Simulation) Acme is a small export company that has an existing enterprise network that is running IPv6OSPFv3. Currently OSPF is configured on all routers. However, R4's loopback address (FEC0:4:4) cannot be seen in R1's IPv6 routing table. You are tasked with identifying the cause of this fault and implementing the needed corrective actions that uses OSPF features and does no change the current area assignments. You will know that you have corrected the fault when R4'sloopback address (FEC0:4:4) can ping from R1 to R4 loopback address. Special Note: To gain the maximum number of points you must remove all incorrect or unneeded configuration statements related to this issue.
