You work as a network administrator at ABC.com.The ABC.com network consists of a single domain named ABC.com.All servers on the ABC.com network have Windows Server 2012 R2 installed and all client computers have Windows 8 installed.The ABC.com network has a single DNS server named ABC_SR09.The client computers are located in an organizational unit （OU） named ABCPCs.You add a new Windows Server 2012 R2 computer named ABC_SR10 to the network  and configure the computer as an Intrasite Automatic Tunnel Addressing Protocol （ISATAP） router. How would you enable the client computers to locate the ISATAP router through DNS？（）

• A、You should run the netsh interface ipv6 install command on the client computers.
• B、You should run the netsh interface ipv6 install command on ABC_SR10.
• C、You should add the host （A） record isatap.ABC.com to the DNS zone.
• D、You should add an IPv6 host （AAA） record for ABC_SR10 to the DNS zone.
• E、You should run the Set-DnsServerGlobalQueryBlockList cmdlet on ABC_SR09.
• F、You should run the Set NetIsatapConfiguration cmdlet on ABC_SR10.

• B、EIGRP for IPv6 is not configured on the interfaces over which it runs， but if a user uses passive-interface configuration， EIGRP for IPv6 needs to be configured on the interface that is made passive.
• C、There is a network statement configuration in EIGRP for IPv6， the same as for IPv4.
• D、There is no network statement configuration in EIGRP for IPv6.
• E、When a user uses a passive-interface configuration， EIGRP for IPv6 does not need to be configured on the interface that is made passive.
• F、When a user uses a non-passive-interface configuration， EIGRP for IPv6 does not need to be configured on the interface that is made passive
