Example Questions

What are two purposes of the BGP scan-time command? (Choose two.) When implementing OSPF, which type of networks require DR/BDR election? What is recursive lookup in BGP and how does it work? Which two of the following are true regarding the BGP Prefix-Based outbound route filtering feature? (Choose two.) In Cisco IOS and Cisco IOS XE Software images, when redistributing routes from other routing protocols into OSPF, what is a common reason why some of the routes might not be redistributed into OSPF? Which reserved AS number or range of numbers is used for backward compatibility between old BGP peers using 16-bit AS number and new BGP peers using 32-bit AS number? You are implementing OSPF as the IGP using a single OSPF area design. The router memory usage for OSPF is too high. Which two methods can lower the OSPF memory usage? (Choose two.) When troubleshooting OSPF neighbor errors, which three verification steps should be considered? (Choose three.) When using the show bgp ipv6 unicast summary command to verify the IPv6 BGP session status with the IPv6 BGP peers, you noticed the "St/PfxRcd" status for one of the IPv6 BGP peers is in the "Active" state. What does the "Active" state indicate? What are two characteristics of the multihomed customers to service providers connection option? (Choose two.) Which of the following is a characteristic of dual-multihomed connectivity between an enterprise network and the service provider network or networks? When redistributing EIGRP routes into OSPF as type E2 external OSPF routes, what is the default OSPF seed metric? Routes that are received from an IBGP peer will be propagated to which other routers by default? Which OSPF feature allows a router with redundant route processors to maintain its OSPF state and adjacencies across planned and unplanned RP switchovers and does this by checkpointing state information from OSPF on the active RP to the standby RP? This feature does not require the OSPF neighbor to support graceful restart. What are two consequences of having constant link flaps, resulting in the OSPF neighbor adjacencies going up and down repeatedly? (Choose two.) Which BGP attribute is a set of generic tags that can be used to signal various routing policies between BGP routers? Which of the following is used by an IS-IS router to detect other IS-IS neighbor routers and to form adjacencies? What is defined by using the Cisco IOS XR policy-global configuration command? Which three statements are true regarding the OSPF router ID? (Choose three.) How can you prevent multihomed customers with connections to two service providers from acting as a transit AS? In which network environment is IS-IS adjacency check important? Which high-availability mechanism is a detection protocol that is enabled at the interface and at the routing protocol levels? When configuring Cisco IOS XR route policy nesting, which command is used within a route policy to call another route policy? What are two ways to advertise networks into BGP? (Choose two.) Which two statements are true about an EBGP session or an IBGP session? (Choose two.) When using the Cisco IOS-XR show bgp command to examine the BGP table, the Metric value being displayed is used to represent which BGP attribute? When implementing LDP, what is liberal label retention mode? Which high-availability routing feature requires the neighbor router to support the graceful restart capability? When redistributing routes into OSPF, which kind of routes will be redistributed by default on Cisco IOS XR Software but will not be automatically redistributed by default on Cisco IOS Software and Cisco IOS XE Software? In comparing IS-IS with OSPF, a Level-1-2 IS-IS router is similar to which kind of OSPF router? Which two statements about a transit AS are correct? (Choose two.)
