6.2.5 ipv6
Your company has started the transition to IPv6. You need to configure records on the DNS server so that clients can submit a hostname query and receive back an IPv6 address for the specified host. What should you do?
Create AAAA records Why: Maps a DNS hostname to a 128-bit ipv6 A = ipv4 ptr - ip address to hostname ns - resource record ID all name servers that perform name resolution for zone
Your company has asked you to look at strategies for migrating from IPv4 to IPv6. Instead of using IPv6 only, you decided you want to allow hosts to use both IPv4 and IPv6 addresses. Which of the following technologies should you implement to allow hosts to use both IPv4 and IPv6 at the same time?
Dual Stack
Addresses that are valid on only the current subnet are known as:
Link-local
Which of the following can be used to verify that the TCP/IP Protocol stack has been properly installed on the host?
Loopback Can be used to verify ip protocol stack is installed on host properly
You manage a small office network with a single subnet. The network is connected to the internet. All client computers run Windows. A single server runs Windows Server 2016. The client computers are not joined to a domain. All hosts use IPv6 addresses on the private network. All computers on the private network are assigned host names (such as Computer1, Computer2, etc.). All hosts use the DNS server provided by the Internet Service Provider (ISP) to resolve hostnames for internet hosts. You need to implement a solution so that hosts on your private network can resolve hostnames for other hosts on the private network. You want to implement the solution with the least amount of effort. What should you do?
Make sure that LLMNR is enabled on all computers. LLMNR - name resolution protocol provides peer-to-peer name resolution when DNS available.
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: Teredo = prefix 2001::32
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: ISATAP = prefix FE80
Which of the following BEST describes the route aggregation feature of IPv6?
Route aggregation combines blocks of addresses as a single route in a routing table to reduce the size of routing tables on the internet.
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. You also want it to work through NAT. Which tunneling method should you use?
Toredo
Which of the following are valid IPv6 addresses? (Select two.)
bab3:b834:45a3:0000:0000:762e:0270:5554 35BC:FA77:4898:DAFC:200C:FBBC:A007:8973 What to look for: 8 octets, A-F, 0-9
