Which two methods should you use to configure a default route on this Oracle Solaris 11 system?

You are configuring a system on your network that was installed using LiveCD. You configured
applied a static IP address to the system. You now need to configure a default router. Assume that
name services are file based and the router’s IP address is 172.31.10.1.
Which two methods should you use to configure a default route on this Oracle Solaris 11 system?

A.
svccfg –s network/physical setprop config/defroute=172.31.10.1;svcadm refresh
network/physical; svcadm restart network/physical

B.
svccfg –s routing/route setprop config/defroute=172.31.10.1;svcadm refresh routing/route;
svcadm restart routing/route

C.
Add the IP address to the /etc/defaultrouter file and run route add default 172.31.10.1.

D.
netadm modify –p ncp DefaultFixed set-prop –p defroute=172.31.10.1

E.
ipadm set-prop –p defaultrouter=172.31.10.1

Explanation:
* AI Server Software Requirements include:
Default router
Ensure that your AI server has a default route set by using the netstat command to show network
status. If your AI server does not have a default route set, you can set a static default route by
populating the /etc/defaultrouter file with the IP address of a static default route for your server’s
network.
* For any currently active NCP (fixed or reactive), use the route command with the -p option to
persistently add a route:
# route -p add default ip-address
Because this command applies the specified route to the currently active NCP, the default route is
removed and potentially replaced, if the active NCP changes.
Incorrect:
Not A, Not B: The svccfg command manipulates data in the service configuration repository.
svccfg can be invoked interactively, with an individual subcommand, or by specifying a command
file that contains a series of subcommands.
