DRAG DROP –
Drag and drop the message types from the left onto the target eld of the message originator on the right.
Which component is similar to an EVPN instance?
- A . router distinguisher
- B . MPLS label
- C . IGP router ID
- D . VRF
Refer to the exhibit. After implementing a new design for the network, a technician reviews the pictures CLI output as part of the MOP.
Which two elements describe what the technician can ascertain from the ImpNull output? (Choose two.)
- A . Ultimate Hop Popping is in use for the pre x displayed.
- B . Penultimate Hop Popping is in use for the pre x displayed.
- C . Label 0 is used for the pre x displayed, but will not be part of the MPLS label stack for packets destined for 192.168.10.10.
- D . Label 3 is in use for the pre x displayed and will be part of the MPLS label stack for packets destined for 192.168.10.10.
- E . Label 0 is used for the pre x displayed and will be part of the MPLS label stack for packets destined for 192.168.10.10.
Refer to the exhibit. The CE router is peering with both PE routers and advertising a public pre x to the internet. Routing to and from this
pre x will be asymmetric under certain network conditions, but packets must not be discarded.
Which configuration must an engineer apply to the two PE routers so that they validate reverse packet forwarding for packets entering their Gi2 interfaces and drop traffic from the RFC1918 space?
- A . ip verify unicast source reachable-via rx allow-default
- B . interface GigabitEthernet 2
ip verify unicast source reachable-via rx - C . ip verify unicast source reachable-via any allow-default interface GigabitEthernet 2
- D . ip verify unicast source reachable-via any
Refer to the exhibit.
P3 and PE4 are at the edge of the service provider core and serve as ABR routers. Aggregation areas are on either side of the core.
Which statement about the architecture is true?
- A . To support seamless MPLS, the BGP route re ector feature must be disabled.
- B . If each area is running its own IGP, BGP must provide an end-to-end MPLS LSP.
- C . If each area is running its own IGP, the ABR routers must redistribute the IGP routing table into BGP.
- D . To support seamless MPLS, TDP must be used as the label protocol.
Which additional configuration is required for NetFlow to provide traceback information?
- A . A classi cation ACL must be configured to identity which type of traffic will be analyzed.
- B . The BGP routing process must be started for any ingress or egress data to be reported when using NetFlow Version 5.
- C . Cisco Express Forwarding must be configured for traffic that is egressing from the router to be property reported.
- D . LLDP must be configured or the device will be unable to locate a NetFlow analyzer.
DRAG DROP –
Drag and drop the technologies from the left onto the correct definitions on the right.
Refer to the exhibit. A network engineer received a complaint about these problems in OSPF stub area 100:
• The Ethernet link is down between routers RX and RY because the ber was cut.
• CE site A traffic to the hub site is being dropped.
Which action resolves these issues?
- A . Change the OSPF area 100 type to stub on RZ.
- B . Set the OSPF MTU to 1500 on the link between RX and RZ.
- C . Set the OSPF authentication type to MD5 between RX and RY.
- D . Change the OSPF priority to 100 on the Interfaces that connect RX and RY.
A network engineer is configuring RIP as the routing protocol between multiple PEs and CEs. The engineer must avoid advertising the same routes back to their sources.
Which action should be performed on the routers to accomplish this task?
- A . De ne the site of origin on each interface.
- B . Con gure a different route distinguisher for each pre x.
- C . De ne VRFs on each device to separate the tra c.
- D . Enable bidirectional forwarding detection on each device.
Refer to the exhibit. An engineering team must update the network configuration so that data traffic from router A to router D continues in case of a network outage between routers B and
C. During a recent outage on the B-C link, the IGP traffic path was switched to the alternate path via routers E and F, but label forwarding did not occur on the new path.
Which action ensures that traffic on the end-to-end path continues?
- A . Con gure the same hello timer values for IGP and LDP
- B . Enable LDP Session Protection on routers A and D
- C . Bind the BFD protocol with IGP on all routers
- D . Enable MPLS LDP IGP Synchronization on all routers
