Demo Questions
Question 1
Which utility can you use to validate an LSP in an MPLS environment?
- uRPF
- MPLS LSP ping
- logging
- RSVP
Correct answer: B
Question 2
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
Correct answer: C
Question 3
The CTO of a company requires the support of a network consultant to deliver an MPLS solution without resigning to a certain degree of redundancy and scalability. Which solution effectively scales to hundreds or thousands of sites?
- L2VPN with the broadcast traffic processed at the ingress PE.
- L3VPN with direct LSP connectivity between all PEs.
- L2VPN by encapsulating multiple frame formats with interworking.
- L3VPN using a hierarchical topology of N-PEs and U-PEs.
Correct answer: D
Question 4
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
Correct answer: C
Question 5
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
Correct answer: D
Question 6
What do EVPN single-active and all-active have in common?
- They are default gateway redundancy options.
- They are multihoming mechanisms used for CE devices.
- They are used to provide single connection from a CE device to a service provider.
- They are both roles that a designated router can take when MPLS is used with EVPN.
Correct answer: B
Question 7
An engineer is troubleshooting an EoMPLS circuit on a Cisco IOS XR router interface that removes a VLAN from the distribution layer. Which configuration should the engineer apply in order to accomplish the task?

Correct answer: C
Question 8
Refer to the exhibit. Drag and drop the EVC configuration items from the left onto the correct descriptions on the right.
Correct answer: To work with this question, an Exam Simulator is required.
Question 9
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.
Correct answer: AB
Question 10
Refer to the exhibit. Which statement about this configuration is true?
- Router 1 will accept multicast routes with a route-target of 12:1.
- 192.168.1.2 must be reachable by all routers participating in the mvpn-intranet MVRF.
- Router 1 has statically defined thresholds for data MDT.
- The MVRF must be configured on each router on the customer and service provider networks.
Correct answer: A
Question 11
Refer to the exhibit. The CE router has established a BGP peering with the PE router, and the CE will use the core infrastructure of the PE as a backbone carrier to support CSC. Which additional task can you perform to complete the configuration?
- Configure static routing on the CE router.
- Configure the address-family ipv4 labeled-unicast command under the neighbor configuration of the CE router for the PE.
- Change the rd value to 65001:65001 under the VRF section of the PE router.
- Configure OSPF on the PE router.
