Demo Questions

Question 1
Which type of VPN requires a full mesh of virtual circuits to provide optimal site-to-site connectivity?

  • A: MPLS Layer 3 VPNs
  • B: Layer 2 overlay VPNs
  • C: GET VPNs
  • D: peer-to-peer VPNs



Question 2
Which three Layer 3 VPN technologies are based on the overlay model? (Choose three.)

  • A: ATM virtual circuits
  • B: Frame Relay virtual circuits
  • C: GRE/IPsec
  • D: L2TPv3
  • E: MPLS Layer 3 VPNs
  • F: DMVPNs



Question 3
Which VPN technology uses the Group Domain of Interpretation as the keying protocol and IPsec for encryption that is often deployed over a private MPLS core network?

  • A: DMVPN
  • B: GET VPN
  • C: SSL VPN
  • D: L2TPv3



Question 4
What is the primary difference between 6PE and 6VPE?

  • A: 6VPE does not require an MPLS core.
  • B: 6VPE requires an IPv6-aware core.
  • C: 6VPE provides IPv6 VPN services.
  • D: 6VPE tunnels IPv6 packets inside IPv4 packets.



Question 5
In MPLS Layer 3 VPN implementations, which mechanism is used to control which routes are imported to a VRF?

  • A: RT
  • B: RD
  • C: VC ID
  • D: PW ID
  • E: VRF ID



Question 6
Which Cisco IOS XR BGP configuration command is required to enable MP-BGP to carry IPv6 VPN routes?

  • A: address-family ipv4 unicast
  • B: address-family ipv6 unicast
  • C: address-family vpnv4 unicast
  • D: address-family vpnv6 unicast



Question 7
Which statement regarding the Cisco IOS BGP configuration exhibit is correct? 

  

  • A: None of the routers will receive IPv4 BGP routes.
  • B: Only the 172.16.2.1 and 172.16.3.1 neighbors will receive both VPNv4 routes and IPv4 BGP routes.
  • C: Only the 172.16.3.1 neighbor will receive both VPNv4 routes and IPv4 BGP routes.
  • D: All three neighbors (172.16.1.1, 172.16.2.1, and 172.16.3.1) will receive both VPNv4 routes and IPv4 BGP routes.
  • E: All three neighbors (172.16.1.1, 172.16.2.1, and 172.16.3.1) will receive IPv4 BGP routes.



Question 8
When implementing MPLS Layer 3 VPNs with customers running OSPF as the CE-PE routing protocol, the service provider MPLS backbone looks like what to the CE routers?

  • A: the backbone (Area 0)
  • B: an external routing domain
  • C: a superbackbone that is transparent to the CE OSPF routers
  • D: a transit area (similar to a transit area for supporting virtual links)



Question 9
When implementing MPLS Layer 3 VPNs with customers running OSPF as the CE-PE routing protocol, which situation will require a sham link to be implemented in the MPLS backbone?

  • A: to connect customer sites in different OSPF areas
  • B: to connect customer sites in the same OSPF area
  • C: to prevent OSPF routing loops when a customer site has redundant CE-PE connections
  • D: if there is a backdoor link between the CE routers, to ensure that the backdoor link is used only to back up the primary connection through the MPLS VPN



Question 10
Which option is used as a loop prevention mechanism to support MPLS VPN customers with multihomed sites?

  • A: BGP down bit
  • B: sham links
  • C: AS override
  • D: SOO extended BGP community
  • E: allow as-in
