Explanation

Oracle Solaris 11 Default Route Configuration

Both A and B correctly leverage SMF (Service Management Facility), the Solaris 11 mechanism for persistent network configuration. Option A configures the default route via the network/physical service (which manages interface-level network settings), while option B targets the routing/route service (dedicated to route management) - both are valid SMF-based paths to persist a default gateway across reboots on a DefaultFixed NCP system.

Why the distractors fail:

• C is the Solaris 10 legacy approach - /etc/defaultrouter is deprecated in Solaris 11, and route add default only configures a temporary, non-persistent route that disappears on reboot.
• D uses netadm, which manages Network Configuration Profiles (NCPs) as a whole, not individual route properties; the syntax is also incorrect for this purpose.
• E uses ipadm, which manages IP interface addresses and properties - it has no defaultrouter property and is not responsible for routing configuration.

Memory tip: In Solaris 11, the rule is "files → services." Anything you'd have done in /etc/defaultrouter or similar files on Solaris 10 now belongs in SMF via svccfg. When you see a persistent network config question on Solaris 11, look for the svccfg option first.
