Demo Questions

Question 1
Automatic 6-to-4 tunnels exist between dual-stack routers (A, B, and C). One router has the IPv6 address, 2002:D030:6BC0:173C::26:37D0/48
Which of the following addresses is the IPv4 address of the router with the IPv6 address 2002:D030:6BC0:173C::26:37D0/48?

  • A:
  • B:
  • C:
  • D:

Question 2
You have recently joined a company as the network administrator. You have been asked to complete the configuration on the border routers for an automatic 6-to-4 tunnel between several IPv6 network domains. The commands that are currently configured on the routers are as follows:
ipv6 route tunnel 
interface tunnel 
ipv6 address 
tunnel source 
Which of the following additional commands is required to complete the configuration of automatic 6-to-4 tunnel on the border routers?

  • A: tunnel mode ipv6ip
  • B: tunnel mode ipv6ip 6to4
  • C: tunnel mode ipv6ip auto-tunnel
  • D: tunnel mode ipv6ip isatap

Question 3
You have implemented IPv6 automatic 6-to-4 tunneling between three IPv6 subnets as shown in the network exhibit. (Click the Exhibit(s) button.) 


You have used the following commands to implement the automatic 6-to-4 tunnel:


Your supervisor has assigned the task of verifying the automatic 6-to-4 tunnel to one of your colleagues. Your colleague runs the show running-config command and finds that incorrect IPv6 addresses have been assigned to the tunnel interfaces of the routers. 
Which of the following IPv6 addresses should be assigned to rectify the problem? (Choose two.)

  • A: 2002::c0a8:2d01/64 to the Fa0/1 interface of rtrA
  • B: 2002:c0a8:4b01::1/64 to the Fa0/1 interface of rtrB
  • C: 2002:c0a8:7d01::1/64 to the Fa0/1 interface of rtrC
  • D: 2002:c0a8:4b01::1/64 to the Fa0/1 interface of rtrA 

Question 4
An automatic IPv4-compatible IPv6 tunnel exists between two IPv6 networks. The two IPv6 networks belong to different BGP autonomous systems (AS). The tunnel source has the IPv4 address and the tunnel destination has the IPv4 address 
Which of the following statements is TRUE about the tunnel source and tunnel destination IPv6 addresses? (Choose two.)

  • A: the IPv6 address of the tunnel source is
  • B: the IPv6 address of the tunnel source is ::
  • C: the IPv6 address of the tunnel destination is
  • D: the IPv6 address of the tunnel destination is ::

Question 5
Your company has implemented IPv6 addresses and routing on every host, server, and router. Recently, your company acquired another company that has an IPv4 addressing scheme for its entire network. The acquired company's network does not have any support for IPv6. You need to devise a method so that the IPv6 hosts in your company can seamlessly communicate with the IPv4 hosts of the acquired company's network. You do not want to install any additional routers, and you want minimum configuration changes on the networks. Which of the following is the best method to allow communication between the IPv4 and IPv6 hosts?

  • A: Embedding IPv6 packets into IPv4 packets 
  • B: Translating IPv4 addresses to and from IPv6 addresses
  • C: Configuring IPv6 on the hosts and routers in the IPv4 network
  • D: ConfiguringIPv4 on the hosts and routers in the IPv6 network

Question 6
Which of the following statements are TRUE about manually configured IPV4-to-IP6 tunnels and GRE tunnels? 
(Choose two.)

  • A: Manually configured tunnels use the tunnel mode ipv6ip command, while GRE tunnels use the tunnel mode gre ip command.
  • B: Manually configured tunnels support IPv6 IGPs, while GRE tunnels do not.
  • C: Manually configured tunnels block IPv6 multicasts, while GRE forwards them.
  • D: Manually configured tunnels do not support multiple passenger protocols, while GRE tunnels support them.

Question 7
Which dialer interface command sets the maximum size of IP packets to 1492?

  • A: router(config-if)# mtu 1492
  • B: router(config-if)# ip ppp 1492
  • C: router(config-if)# ip 1492 
  • D: router(config-if)# ip mtu 1492

Question 8
Examine the following FIB table:


Which of the following statements is NOT true?

  • A: These are the default entries in an FIB table
  • B: No IP addresses have been configured on this router
  • C: Multicast routing is enabled
  • D: The gateway of last resort has not been set

Question 9
Which of the following IPv6/IPv4 interoperability techniques routes both IP versions simultaneously?

  • A: NAT-PT
  • B: Dual stack
  • C: 6to4 tunnels
  • D: Teredo

Question 10
An enterprise has implemented an IPv4 addressing scheme on the servers of its core network. To effectively handle the increasing user requests to the server, the enterprise has plans to implement three new subnets with IPv6 addressing in its existing IPv4 network. The network administrator has set up dual-stack routers on the boundary of these subnets, as shown in the network diagram. 


You need to ensure interoperability between IPv4 and IPv6 hosts such that routers A, B, and C can dynamically determine the destination of an IPv6 packet. In addition, global unicast addresses should be supported on all hosts in the three IPv6 subnets. 
Which of the following tunneling method can be used between the three routers? (Choose two.) 

  • A: GRE tunnel
  • B: Automatic 6-to-4 tunnel
  • C: ISATAP tunnel
  • D: Manually-configured tunnel
