Demo Questions
Question 1
In a VPRN the PE device is configured to run which of the following protocols? (Choose three.)
- MP-BGP for exchanging customer routes with other PEs
- A routing protocol for exchanging customer routes with the CE
- MPLS for exchanging labels with other provider core devices
- MPLS for exchanging labels with the CE devices
- Targeted LDP for exchanging VPRN labels with other PE devices
- A label signaling protocol for defining transport tunnels between PE and CE devices
Correct answer: ABC
Question 2
Choose the answer that best completes the following sentence. The CE device is typically configured with _________________.
- A single routing protocol for exchanging routes with both the internal customer routers and with the PE
- MP-BGP to exchange routes with the PE.
- MPLS and a routing protocol for the exchange of labels and routes with the PE
- MPLS for exchanging labels with other CE devices
- A routing protocol for exchanging routes with the internal customer routers and a routing protocol for exchanging routes with the PE
Correct answer: E
Question 3
Which of the following terms also correctly describes a Layer 3 VPN?(Choose three)
- VPRN
- BGP/MPLS VPN
- VLL
- VPLS
- IP-VPN
- ePipe
Correct answer: ABE
Question 4
Which of the following statements are true regarding P devices in an MPLS VPRN? (Choose two.)
- Participate in service provider core routing
- P devices are not required to be MPLS enabled. MPLS is only required on the PE devices
- Run a common routing protocol with the CE router
- Must support MP-BGP
- Do not have any connections to the CE
- Must be aware of the VPRNs
Correct answer: AE
Question 5
When a Service Provider offers VPRN services to its customers, which of the following functions are expected to be the responsibility of the Service Provider? (Choose three)

- Distributing the customer routing information between
- Forwarding the customer originated data packets to the appropriate destination
- Forwarding the provider originated data packets to the appropriate customer site
- Providing secure layer 3 routing exchange between sites
Correct answer: BCE
Question 6
In a traditional layer 3 VPN which of the following will be an issue when there is overlapping address space between two customers? Choose the best answer.
- There will be increased memory usage on the PE
- There will be increased CPU utilization on the PE
- The CE will reject the overlapping prefix
- The PE will not recognize the prefixes as being different
- There is no issue with overlapping address space in a traditional Layer 3 VPN
Correct answer: D
Question 7
Complete the following statement. In a VPRN, the label signaled by RSVP-TE is used to ______________.
- Identify the egress PE in the MPLS domain
- Signal the egress VPRN ID
- Identify the ingress PE in the MPLS domain
- Transport route updates between PEs
Correct answer: A
Question 8
What operation is performed by a P device on the label signaled by MP-BGP when it receives a labeled packet for a VPRN service?
- It will label switch the packet based on this label
- It will decrement the TTL and label switch the packet based on this label
- It will SWAP the label for a new label and then label switch the packet
- The P router does not perform any operation on this label
Correct answer: D
Question 9
Which of the following statements is true? Choose the best answer.
- A P router may forward customer packets to their destination without the presence of a route to that destination
- The ingress PE router may forward customer packets to their destination without the presence of a route to that destination
- The egress PE router may forward customer packets to their destination without the presence of a route to that destination
- Any provider core router (P or PE) may forward customer packets to their destination without the presence of a route to that destination
Correct answer: A
Question 10
Which of the following statements is true regarding the Route Distinguisher? (Choose three)

- To ensure uniqueness, Route Distinguishers are assigned by the IANA.
- The Route Distinguisher is not used if the customer addresses do not overlap
- The Assigned Number field must contain a public IP address
Correct answer: ABC
