Demo Questions

Question 1
Which are the three characteristics of SDR? (Choose three.)

  • A: The logical router has dedicated route processor.
  • B: Owner SDR can be reloaded without affecting all non-SDRs.
  • C: The fabric and system controller module are shared by all logical routers.
  • D: The logical router can share line cards.
  • E: The logical router can span across chassis.
  • F: Each logical router has a distinct fabric and system controller module.

Question 2
On Cisco IOS XR platform, why would an engineer use the load rollback command instead of the rollback command?

  • A: to revert commits with IDs 100000005 10000007 simultaneously.
  • B: to revert a change even after a subsequent change is made.
  • C: to revert changes to RLP objects.
  • D: to revert changes to admin mode configuration.

Question 3
Which two options are considered nodes in Low-power Lossy Networks? (Choose two.)

  • A: routers
  • B: access points
  • C: controllers
  • D: sensors
  • E: servers

Question 4
A service provider is using Cisco ME 3400 Series Ethernet Access Switches on the access edge of Metro Ethernet POP. A customer has a requirement to connect a switch to the network and requires the ability to trunk VLANs on the uplink port into the provider network. 
Which port type should the engineer configure on the switch to meet the requirement while maintaining a secure success edge implementation?

  • A: UNI
  • B: ENI
  • C: NNI
  • D: access

Question 5
An engineer sees that traffic is not flowing between two line cards on a Cisco ASR 9000 Series device. To troubleshoot this issue, what should the engineer do first?

  • A: Verify whether there are errors on the EOBCs.
  • B: Verify whether there are PFM alarms on the line cards and RSPs.
  • C: Verify whether LPTS configuration is prohibiting traffic between the two line cards.
  • D: Verify whether there are alarms in the system diagnostics.

Question 6
What is a general limitation of satellite NV system network topologies?

  • A: All advanced Satellite nV network topologies are supported on the Cisco ASR1000v.
  • B: A satellite can be connected to only one host in the hub-and-spoke topology model.
  • C: SyncE is supported on two gigabit ethernet ICL in hub-and-spoke topology model.
  • D: Only one host can be paired with a satellite in a dual-homed network architecture.

Question 7
What is one of the necessary prerequisites for MPLS Traffic Engineering Inter-AS TE?

  • A: Cisco Express Forwarding is supported on the network.
  • B: Midpoint reoptimization is configured.
  • C: IPv6 is configured.
  • D: Network must support BGP.

Question 8
With regards to the IPv6 transition mechanism, which two tunneling disadvantages are? (Choose two.)

  • A: Tunneling techniques are not scalable because they cannot be dynamically created, they must be manually created.
  • B: Users of the new architecture cannot use the services of the underlying infrastructure.
  • C: IPv6 needs to be activated on almost of the network elements in the existing network, posing business continuity challenges.
  • D: Tunneling does not enable users of the new protocol to communicate with users of the old protocol without dual stack hosts, which negates the interoperability.
  • E: Tunneling provides a gradual migration to IPv6 network by providing seamless Internet experience to greenfield IPv6 only users to access IPv4 Internet services.

Question 9
Which function is shared amongst all SDRs in a system of Cisco routers running IOS XR?

  • A: Protocols
  • B: Switch Fabric
  • C: Configuration
  • D: Routing Table

Question 10
Which Cisco IOS XR Virtualization technology provides full isolation between virtualized routing instances for multiple tenants?

  • A: VRF
  • B: SDR
  • C: HVR
  • D: VRF Lite
