Cisco 300-510 Implementing Cisco Service Provider Advanced Routing Solutions Exam Practice Test Questions

• Question 1

  What are two differences between OSPF and IS-IS? (Choose two.)

  • OSPF is a link-state routing protocol, and IS-IS is a distance-vector routing protocol.
  • OSPF uses a router ID to identify a router, and IS-IS uses a system ID.
  • OSPF elects a DR and a BDR, and IS-IS elects a DIS.
  • Unlike OSPF. IS-IS supports virtual links.
  • Unlike IS-IS routers, an OSPF router belongs to only one area in addition to the backbone area.

• Question 3

  Which difference should be considered when intradomain or interdomain multicast routing is implemented?

  • Interdomain multicast routing requires an IS-IS or OSPF neighbor relationship between the domains but intradomain multicast routing requires only BGP
  • Interdomain multicast routing relies on PIM-DM and intradomain multicast routing relies on PIM-SM.
  • Interdomain multicast routing uses BIDR-PIM to establish neighbor relationships between AS and interdomain multicast routing uses MSDP
  • A network uses intradomain multicast routing without interdomain routing but networks that use interdomain multicast routing must also apply intradomain routing

• Question 4

  You have configured MSDP peering between two autonomous systems that pass traffic between two sites, but the peering has failed to come up.Which task do you perform to begin troubleshooting the problem?

  • Verify that multicast has been disabled globally
  • Verify that PIM-DM is configured on the source interface
  • Verify that both source interfaces are reachable from both peers
  • Verify that the two MSDP peers allow asymmetric routing

• Question 5

  You have configured routing policies on a Cisco IOS XR device with routing policy language. Which two statements about the routing policies are true? (Choose two.)

  • The routing policies affect BGP-related routes only.
  • If you make edits to an existing routing policy without pasting the full policy into the CLI, the previous policy is overwritten.
  • You can change an existing routing policy by editing individual statements.
  • The routing policies are implemented in a sequential manner.
  • The routing policies are implemented using route maps.
