The router IP 192.168.1.2 sent an implicit null, and the output is from the penultimate LSR.

The adjacent router is the egress LSR and has mpls ldp explicit-null configured.

The adjacent LSR router configured mpls label range 0.

The zero in the second column is the normal behavior of an egress router LSR.

Q26. A network engineer is implementing Layer 3 MPLS VPNs on Cisco IOS/IOS XE PE routers. Which PE-to-CE routing protocol requires a separate routing process to be created for each VRF?

RIPv2

OSPF

BGP

EIGRP

Q27. Which two are characteristics of using a non-MPLS peer-to-peer model over a traditional overlay model?
(Choose two.)

The model is suited for nonredundant configurations.

The configuration on a newly added site PE is updated automatically.

Provider routers know the customer network topology.

The customer specifies the exact site-to-site traffic profile.

Routing information is exchanged between the customer router and one or a few PEs.

Q28. Which two statements describe primary differences between MPLS Layer 2 and Layer 3 VPNs? (Choose two.)

Layer 2 VPNs use IPsec tunneling, but Layer 3 VPNs use L2TPv3 tunneling.

Layer 2 VPNs use AToM, but Layer 3 VPNs use MPLS/BGP.

Layer 2 VPNs use BGP, but Layer 3 VPNs use VPLS.

Layer 2 VPNs use L2TPv3 tunneling, but Layer 3 VPNs use GRE tunneling.

Layer 2 VPNs use IPsec tunneling, but Layer 3 VPNs use pseudowires to provide tunneling.

Q29. You are troubleshooting ARP connectivity issues for an Ethernet interface on an IOS XR network that runs IS- IS. You verify that the IGP protocol is running, but an ARP entry has not yet been created.
Which action should you take?

debug ping packets

debug ARP

ping the connected neighbor

verify the RIB table routes

Q30. While configuring the VRF Selection feature, you get an error message after typing the below statement:
Router(config)#no vrf selection source 172.16.0.0 255.255.0.0 vrf VRF1
Which action caused this message?

the entry of an inconsistent IP address and mask for VRF Selection

an attempt to configure a VRF instance on an interface that already has VRF Selection configured

an attempt to remove a VRF Selection entry that does not exist

an attempt to configure a VRF Selection table that does not exist

Q31. While troubleshooting an AToM L2VPN service, a network consultant notices that the AC Layer 2 encapsulations are different. Which action should the consultant take in order to make the MPLS L2VPN work?

tag-rewrite on the ingress and egress PE router

interworking IP configuration on the last PE router before label disposition

nonrouted interworking setup to properly translate only the Layer 2 information from the AC

interworking IP configuration on both the AC terminations on the PEs

Q32. What must match in the EVPN and L2VPN configuration mode when configuring EVPN native in a router?

interface

address family

bridge domain

EVI

Q33. An engineer is investigating an EVPN traffic flow issue. Which type of traffic should the engineer allow in an EVPN Tree Service in order to fix this issue?

known unicast from a leaf to another leaf

unknown unicast from a leaf to another leaf

multicast from a leaf to another leaf

known unicast from a root to another root

Q34. Refer to the exhibit. A network engineer has been called to configure the four PE devices in order to enable full communication among the four CE devices connected to them. While starting to configure, he experienced a connectivity issue.
Which two tasks should the engineer perform in order to begin the process correctly? (Choose two.)

Configure PE3 to export route-targets 100:1 and 200:2.

Configure PE3 to import route-targets 100:1 and 200:2.

Configure PE4 to import route-targets 101:1 and 202:2.

Configure PE2 to export route-targets 300:3 and 400:4.

Configure PE1 to import route-targets 300:3 and 400:4.

Q35. Which mechanism reduces the network flooding caused by host ARP learning behavior?

ARP suppression

storm control

root guard

BPDU guard

Q36. Refer to the exhibit.

Refer to the exhibit Router 1 is a P router in the ISP MPLS core A connected P router cannot generate an MPLS label for the router 1 loopback0 interface Which action resolves this issue?

The loopback0 interface must be in OSPF area 0.

The network statement under the routing process must have a wildcard mask of 0 0.0 255.

The OSPF network type must be changed on loopback0 to point-to-point

A static route to null 0 must be added for the loopback interface and then static routes must be redistributed into OSPF

Q37. How do Ethernet virtual circuits provide a way for service providers to maximize the use of VLAN tags’-1

They add an additional tag to VLANs that allows up to two switch ports to use the same globally configured VLAN ID.

They redefine the VLAN tag to include classification, forwarding, and QoS using MPLS labels and EXP bits

They separate the classification and forwarding concepts for VLAN tagging which allows multiple switch ports to use the same VLAN ID without it being configured globally.

They assign VLAN IDs to VTP domains so that the same VLAN ID are used more than once globally.

Q38. You try to configure MPLS VPN VRF Selection based on a source IP address on an interface that has VRF configured, but you receive an error.
Which action must you take to correct the problem?

Change the source IP address.

Add the IP address to the VRF table.

Remove the VRF from the interface.

Configure static routes for the VRF.
