4to6 tunneling
You manage a network with two locations, Portland and Seattle. Both locations are connected to the internet. All computers in both locations are configured to use IPv6. You would like to implement an IPv6 solution to meet the following requirements: • Hosts in each location should be able to use IPv6 to communicate with hosts in the other location through the IPv4 internet. • You want to use a site-to-site tunneling method instead of a host-to-host tunneling method. Which IPv6 solution should you use?
6to4
Your ISP has assigned you the IP address of 172.22.19.0 with a default subnet mask of 255.255.255.0. You need to create three subnets to meet the following requirements: • Subnet A = 60 hosts • Subnet B = 25 hosts • Subnet C = 31 hosts To provide the minimal number of hosts possible for each subnet, what values should you use?
A = Subnet address 172.22.19.64 with a mask of 255.255.255.192 B = Subnet address 172.22.19.32 with a mask of 255.255.255.224 C = Subnet address 172.22.19.192 with a mask of 255.255.255.192

An employee in your organization has started to work from home two days a week. The employee uses a company laptop for work in both the office and at home. The laptop automatically connects to the wireless network in the office, but does not automatically connect to the employee's home wireless network. The employee would like the laptop to connect automatically both at home and at work. What should you do?
Configure an alternate TCP/IP configuration on the laptop's wireless adapter to use a static IP address that is compatible with the home network.
You have just received a new laptop at work that you will use on your company network and at home. The company network uses dynamic addressing, while your home network uses static addressing. You connect the laptop to the company network and everything works fine. When you take your laptop home you can connect to the devices on your home network or the Internet. You run ipconfig on the laptop and receive the following output: Connection-specific DNS suffix. . . : IPv4 Address . . . . . . : 169.254.22.74 Subnet Mask . . . . . : 255.255.0.0 Default Gateway. . . . . : You need to be able to connect both the company network and your home network with the least amount of configuration and cost. What should you do?
Configure an alternate TCP/IP configuration.
You have installed a test network with one server and two Windows workstations. All are running IPv6. You have disabled IPv4, and now you want to test to make sure that IPv6 is used to communicate between hosts. You want to ping the link-local address for a host. Which command can you use to do this?
Ping FE80::AB134:7845:10C:9956%12
You manage a Windows network environment. As part of your IPv6 migration strategy, you have implemented Teredo on your network. You would like to test the communication of a client computer using Teredo. What should you do?
Ping the address beginning with 2001:
You manage a Windows network environment. As part of your IPv6 migration strategy, you have implemented ISATAP on your network. You would like to test the communication of a client computer using ISATAP. What should you do?
Ping the address beginning with FE80:
You need to design a network that supports 275 hosts. You want to place all hosts in a single broadcast domain, and you want to make sure you do not waste IP addresses. How should you implement your plan?
Place all hosts on the same subnet. Use a mask of 255.255.240.0.
You use a Windows system. Your company has begun migrating your network to IPv6. Your network administrator tells you that the network is using stateless autoconfiguration. You need to configure your computer to use the correct IPv6 address, default gateway address, and DNS server address. The computer is currently configured to get all IPv6 information automatically. What should you do?
Run netsh interface ipv6 add dnsserver.
Your network has just transitioned from using IPv4 to IPv6. IPv6 configuration is performed automatically using information received by network routers. The network does not use a DHCPv6 server. Your Windows system is unable to communicate with a server named Srv1. A ping test to the server works using its IPv6 address, but fails when you use its host name. What should you do?
Run netsh with the add dnssserver option.
You manage a network that uses IPv6 addressing. When clients connect devices to the network, they generator an interface ID and use Neighbor Discovery Protocol (NDP) to learn the subnet prefix and default gateway. Which IPv6 address assignment method is being used?
Stateless autoconfiguration
Match the IPv6 address configuration method on the right with its definition on the left.
Static Full Assignment: The entire 128-bit address and all other configuration information is statically assigned to the host. Static Partial Assignment: The prefix is statically assigned, and the interface ID is derived from the MAC address. Stateless Configuration: Clients automatically generate the interface ID and learn the subnet prefix and default gateway through the neighbor discovery protocol (NDP). Stateful DHCPv6: Provides each client with an IP Address, default gateway, and other IP configuration information. Stateless DHCPv6: Supplies the client with the DNS server IP address only. Does not provide the client with an IP address, and does not track the status of each client.
Your ISP has assigned you a Class C IP address with a default subnet mask of 255.255.255.0. You need to create three subnets, meeting the following usable host requirements: • Subnet A = 50 hosts • Subnet B = 15 hosts • Subnet C = 65 hosts Without wasting host addresses, which subnet masks should you use?
SubnetA = 255.255.255.192 SubnetB = 255.255.255.224 SubnetC = 255.255.255.128
You have an IPv4 network that has two IPv6-only hosts that need to be able to communicate with each other. You want to implement a solution that only requires you to configure the two IPv6 hosts and that also works through NAT. What tunneling method should you use?
