Demo Questions

Question 1
Refer to the exhibit.
A network engineer with an employee ID: 5100:21:535 must configure routers PEA and PEB so that traffic between CE1 and CE2 is multihomed and load-balanced. The two 10GE links in Ethernet bundle 10 are sending traffic at different rates. Which action must the engineer take on PEX and PEY to complete the configuration?
  1. Set the identifier type 11.12.11.12.11.12.11.12.11 on the PEX and PEY routers.
  2. Change the source and destination AC values to 5 and 6 respectively.
  3. Set the identifier type 33.34.33.34.33.34.33.34.33 on the PEX and PEY routers.
  4. Set the neighbor evpn vpi value to 200 on the PEX and PEY routers.
Correct answer: A
Question 2
What is the role of the BGP protocol in CE-to-PE communication?
  1. It performs label exchange only.
  2. It performs routing and label forwarding.
  3. It performs IPv6 route exchange with label forwarding only.
  4. It performs IPv4 and IPv6 route exchange.
Correct answer: B
Question 3
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 4
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?
  1. the entry of an inconsistent IP address and mask for VRF Selection
  2. an attempt to configure a VRF instance on an interface that already has VRF Selection configured
  3. an attempt to remove a VRF Selection entry that does not exist
  4. an attempt to configure a VRF Selection table that does not exist
Correct answer: C

Question 6
Refer to the exhibit. If the two devices are operating normally, which two conclusions can you draw from this configuration? (Choose two.)
  1. CE1 must use OSPF to establish a neighbor relationship with PE1.
  2. PE1 labels the routes it learns from CE1 with the route-target 222:2 and shares them with its VPNv4 peers.
  3. PE1 labels the routes it learns from CE1 with the route-target 111:1 and shares them with its VPNv4 peers.
  4. The PE-CE routes between the devices are being exchanged by OSPF
  5. CE1 is supporting CSC.
Correct answer: A, C
Question 7
Which utility can you use to validate an LSP in an MPLS environment?
  1. uRPF
  2. MPLS LSP ping
  3. logging
  4. RSVP
Correct answer: B
Question 8
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?
  1. tag-rewrite on the ingress and egress PE router
  2. interworking IP configuration on the last PE router before label disposition
  3. nonrouted interworking setup to properly translate only the Layer 2 information from the AC
  4. interworking IP configuration on both the AC terminations on the PEs
Correct answer: D

Which action should you take?
  1. debug ping packets
  2. debug ARP
  3. ping the connected neighbor
  4. verify the RIB table routes
Correct answer: C
Question 10
Refer to the exhibit. What is the effect of this configuration?
  1. The mroute table is cleared.
  2. Router 1 accepts multicast routes with a tag of 12:1
  3. A Cisco MPLS TE tunnel is generated with 192.168.1.2 as the source IP address of router 1.
  4. An LSP virtual interface tunnel is created.
