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: 10.176.15.131 
  • B: 10.200.80.67
  • C: 208.48.107.192
  • D: 208.138.16.110



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 172.168.111.65/24 and the tunnel destination has the IPv4 address 172.168.222.80/24. 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 172.168.111.65::
  • B: the IPv6 address of the tunnel source is ::172.168.111.65 
  • C: the IPv6 address of the tunnel destination is 172.168.222.80:: 
  • D: the IPv6 address of the tunnel destination is ::172.168.222.80 



Question 5
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 6
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 7
Which of the following statements represent characteristics of an automatic 6to4 tunnel through an IPv4 network? (Choose all that apply.)

  • A: There is a NAT-PT router on either end of the tunnel.
  • B: There is a dual stack router on either end of the tunnel.
  • C: Each 6to4 site will have a /48 prefix.
  • D: Each 6to4 site will have a /16 prefix.
  • E: The IPv4 addresses of the edge routers are part of the site prefix.
  • F: The IPv6 addresses of the sending and receiving IPv6 hosts are part of the site prefix.



Question 8
Examine the following output.  

        
  
What possible reason(s) can cause the state of the first entry in the adjacency table? (Choose all that apply.)

  • A: the interface is a multipoint interface
  • B: the clear ip arp command was executed
  • C: the Layer 3 information is unknown
  • D: the clear adjacency command was executed



Question 9
You have been alerted that TCP traffic leaving an interface has been reduced to near zero, while UDP traffic is steadily increasing at the same time.   
What is this behavior called and what causes it?

  • A: jitter, caused by lack of QoS
  • B: latency, caused by the MTU
  • C: starvation, caused improper configuration of QoS queues
  • D: windowing, caused by network congestion



Question 10
Refer to the following set of commands: 

        
  
Which of the following statements is TRUE about the given set of commands?

  • A: IPv4 and IPv6 are running simultaneously on rtrA   
  • B: The IPv4 address is translated to an IPv6 address
  • C: The IPv6 address is an IPv4-compatible address
  • D: A tunnel is created for the interoperability of the IPv4 and IPv6 addresses
