Free Service Provider Routing and Switching, Professional Exam (JNCIP-SP) Exam JN0-664 Exam Practice Test

Which statement is true regarding BGP FlowSpec?

• It uses a remote triggered black hole to protect a network from a denial-of-service attack.
• It uses dynamically created routing policies to protect a network from denial-of-service attacks
• It is used to protect a network from denial-of-service attacks dynamically
• It verifies that the source IP of the incoming packet has a resolvable route in the routing table

Which two statements describe PIM-SM? (Choose two)

• Routers with receivers send join messages to their upstream neighbors.
• Routers without receivers must periodically prune themselves from the SPT.
• Traffic is initially flooded to all routers and an S,G is maintained for each group
• Traffic is only forwarded to routers that request to join the distribution tree.

Which statement is correct about IS-IS when it performs the Dijkstra algorithm?

• The local router moves its own local tuples into the candidate database
• When a new neighbor ID in the tree database matches a router ID in the LSDB, the neighbor ID is moved to the candidate database
• Tuples with the lowest cost are moved from the tree database to the LSDB.
• The algorithm will stop processing once the tree database is empty.

You are configuring a BGP signaled Layer 2 VPN across your MPLS enabled core network. Your PE-2 device connects to two sites within the s VPNIn this scenario, which statement is correct?

• By default on PE-2, the site's local ID is automatically assigned a value of 0 and must be configured to match the total number of attached sites.
• You must create a unique Layer 2 VPN routing instance for each site on the PE-2 device.
• You must use separate physical interfaces to connect PE-2 to each site.
• By default on PE-2, the remote site IDs are automatically assigned based on the order that you add the interfaces to the site configuration.

Which two EVPN route types are used to advertise a multihomed Ethernet segment? (Choose two )

• Type 1
• Type 3
• Type 4
• Type 2

What is the correct order of packet flow through configurable components in the Junos OS CoS features?

• Multifield Classifier -> Behavior Aggregate Classifier -> Input Policer -> Forwarding Policy Options -> Fabric Scheduler -> Output Policer -> Rewrite Marker -> Scheduler/Shaper/RED
• Behavior Aggregate Classifier -> Multifield Classifier -> Input Policer -> Forwarding Policy Options -> Fabric Scheduler -> Output Policer -> Scheduler/Shaper/RED -> Rewrite Marker
• Behavior Aggregate Classifier -> Input Policer -> Multifield Classifier -> Forwarding Policy Options -> Fabric Scheduler -> Output Policer -> Scheduler/Shaper/RED -> Rewrite Marker
• Behavior Aggregate Classifier -> Multifield Classifier -> Input Policer -> Forwarding Policy Options -> Fabric Scheduler -> Scheduler/Shaper/RED -> Output Policer -> Rewrite Marker

Your organization manages a Layer 3 VPN for multiple customers To support advanced route than one BGP community on advertised VPN routes to remote PE routers.Which routing-instance configuration parameter would support this requirement?

• vrf-export
• vrf-import
• vrf-target export
• vrf-target import

Which two statements are correct about the customer interface in an LDP-signaled pseudowire? (Choose two)

• When the encapsulation is vlan-ccc or extended-vlan-ccc, the configured VLAN tag is not included in the control plane LDP advertisement
• When the encapsulation is ethernet-ccc, only frames without a VLAN tag are accepted in the data plane
• When the encapsulation is vLan-ccc or extended-vlan-ccc, the configured VLAN tag is included in the control plane LDP advertisement
• When the encapsulation is ethemet-ccc, tagged and untagged frames are both accepted in the data plane.

You want to ensure that L1 IS-IS routers have only the most specific routes available from L2 IS-IS routers. Which action accomplishes this task?

• Configure the ignore-attached-bit parameter on all L2 routers.
• Configure all routers to allow wide metrics.
• Configure all routers to be L1.
• Configure the ignore-attached-bit parameter on all L1 routers

You are responding to an RFP for a new MPLS VPN implementation. The solution must use LDP for signaling and support Layer 2 connectivity without using BGP The solution must be scalable and support multiple VPN connections over a single MPLS LSP The customer wants to maintain all routing for their Private networkIn this scenario, which solution do you propose?

• circuit cross-connect
• BGP Layer 2 VPN
• LDP Layer 2 circuit
• translational cross-connect
