Your network contains two subnets. The subnets are configured as shown in the following table.

You have a server named Server2 that runs Windows Server 2012. Server2 is connected to LAN1.
You run the route print command as shown in the exhibit. (Refer to the Exhibit.)

You need to ensure that Server2 can communicate with the client computers on LAN2.
What should you do?

A.
Change the metric of the 10.10.1.0 route.

B.
Set the state of the Teredo interface to disable.

C.
Set the state of the Microsoft ISATAP Adapter #2 interface to disable.

D.
Run route delete 172.23.2.0.

Explanation:
Route is used to view and modify the IP routing table. Route Print displays a list of current routes that the host
knows. Default gateways are important to make IP routing work efficiently.
TCP/IP hosts rely on default gateways for most of their communication needs with hosts on remote
networksegments. In this way, individual hosts are freed of the burden of having to maintain extensive
andcontinuously updated knowledge about individual remote IP network segments. Only the router that acts as
thedefault gateway needs to maintain this level of routing knowledge to reach other remote network segments
inthe larger internetwork.
If the default gateway fails, communication beyond the local network segment may be impaired. To preventthis,
you can use the Advanced TCP/IP Settings dialog box(in Network Connections) for each connection tospecify
multiple default gateways. You can also use the route command to manually add routes to therouting table for
heavily used hosts or networksIf you have multiple interfaces and you configure a default gateway for each
interface, TCP/IP by defaultautomatically calculates an interface metric that is based on the speed ofthe
interface. The interface metricbecomes the metric of the default route in the routing table for the configured
default gateway. The interfacewith the highest speed has the lowest metric for its default route. The result is
that whenever multiple defaultgateways are configured on multiple interfaces, the fastest interface will be used
to forward traffic to its defaultgateway.
If multiple interfaces of the same speed have the same lowest interface metric, then, based upon the
bindingorder, the default gateway of the first network adapter is used. The default gateway for the second
networkadapter is used when the first is unavailable.
In order for Host A on Network 1 to communicate with Host B on Network 2, Host A first checks its routing
tableto see if a specific route to Host B exists. If there is no specific route to Host B, Host A forwards its TCP/
IPtraffic for Host B to its own default gateway, IPRouter 1.
