You have set up an email server that needs to respond to email requests by using mail.coolgadgets.com and mail.niftytools.com in the request URL. How can you do this? -Install two NICs, and assign the same IP address to both NICs. Configure DNS to map one MAC address to mail.coolgadgets.com and the other MAC address to mail.niftytools.com. -Configure two IP addresses on one NIC. Configure DHCP to map one IP address to mail.coolgadgets.com and the other IP address to mail.niftytools.com. -Install two NICs, and assign different IP addresses to each NIC, but make sure both IP addresses use the same network ID. Configure the NICs to use default gateways on different networks. -Install two NICs, and connect each one to a different network. Set up the router on each network to forward mail packets to the NIC bound to the correct URL.

Configure two IP addresses on one NIC. Configure DHCP to map one IP address to mail.coolgadgets.com and the other IP address to mail.niftytools.com.

Which IPv6 transition technology requires the netsh command to manually create the tunnel to carry IPv6 traffic over the IPv4 Internet? -6to4 -IPv6-over-IPv4 -Teredo -ISATAP

IPv6-over-IPv4

Which of the following IPv6 transition technologies is enabled by default in Windows Server 2016 and embeds an IPv4 address in a link-local IPv6 address? -IPv6-over-IPv4 -6to4 -ISATAP -Teredo

ISATAP

Which of the following IPv6 autoconfiguration methods utilizes an autoconfiguration protocol, such as DHCPv6, to acquire an IPv6 address? -Stateless autoconfiguration -Static IPv6 configuration -Stateful autoconfiguration -Prefixed IPv6 autoconfiguration

Stateful autoconfiguration

You have a server with two NICs, each attached to a different IP network. You're having problems communicating with devices on remote networks that send packets to one of the interfaces. The server receives the packets fine, but the server's replies never reach the intended destination network. Replies to packets that come in through the other interface seem to reach their destination without any problems. What can you do that will most likely solve the problem? -Use the route command to add routes to the networks that aren't receiving replies. -Replace the NIC that's having problems replying to packets. -Configure a second default gateway on the interface exhibiting problems. -Change the default gateway to use the router that's on the network of the interface exhibiting problems.

Use the route command to add routes to the networks that aren't receiving replies.
