Question 116

Refer to the exhibit. An engineer must establish multipoint GRE tunnels between hub router R6 and branch routers R1, R2, and R3. Which configuration accomplishes this task on R1?

  1. interface Tunnel 1 ip address 192.168.1.1 255.255.255.0 tunnel source e0/0 tunnel mode gre multipoint ip nhrp nhs 192.168.1.6 ip nhrp map 192.168.1.6 192.1.10.1 ip nhrp map 192.168.1.2 192.1.20.2 ip nhrp map 192.168.1.3 192.1.30.3
  2. interface Tunnel 1 ip address 192.168.1.1 255.255.255.0 tunnel source e0/1 tunnel mode gre multipoint ip nhrp nhs 192.168.1.6 ip nhrp map 192. 168.1.6 192.1.10.6
  3. interface Tunnel 1 ip address 192.168.1.1 255.255.255.0 tunnel source e0/0 tunnel mode gre multipoint ip nhrp network-id 1 ip nhrp nhs 192.168.1.6 ip nhrp map 192.168.1.6 192.1.10.6

Question 117

How is VPN routing information distributed in an MPLS network?

  1. The top level of the customer data packet directs it to the correct CE device.
  2. It is established using VPN IPsec peers.
  3. It is controlled through the use of RD.
  4. It is controlled using of VPN target communities.

Question 118

IPv6 is enabled in the infrastructure to support customers with an IPv6 network over WAN and to connect the head office to branch offices in the local network. One of the customers is already running IPv6 and wants to enable IPv6 over the DMVPN network infrastructure between the headend and branch sites. Which configuration command must be applied to establish an mGRE IPv6 tunnel neighborship?

  1. ipv6 nhrp holdtime 30
  2. tunnel mode gre multipoint ipv6
  3. ipv6 unicast-routing
  4. tunnel protection mode ipv6

Question 119

What is a characteristic of Layer 3 MPLS VPNs?

  1. Traffic engineering capabilities provide QoS and SLAs.
  2. Traffic engineering supports multiple IGP instances.
  3. LSP signaling requires the use of unnumbered IP links for traffic engineering.
  4. Authentication is performed by using digital certificates or preshared keys.

Question 120

How does an MPLS Layer 3 VPN differentiate the IP address space used between each VPN?

  1. by RT
  2. by address family
  3. by RD
  4. by MP-BGP
