When upgrading an existing system from Solaris 11 Express to Oracle Solaris 11, what happens
to the datalink names?
A.
They follow the default naming convention for the newly installed version.
B.
They maintain their names.
C.
They are called eth#.
D.
They are called el00g#.
E.
They are left unnamed, to avoid conflicts, and need to be renamed after the installation process
is complete.
Explanation:
Network configuration in Oracle Solaris 11 includes
* Generic datalink name assignment – Generic names are automatically assigned to
datalinks using the net0, net1, netN naming convention, depending on the total number of network
devices that are on the system
Note: There is no upgrade path from Oracle Solaris 10 to Oracle Solaris 11. You must perform a
fresh installation.

I am confused maybe B or A or E
recording to definition below the correct answer must be B.Anyone to confirm that?
Link Names on Upgraded Systems
On systems where the Oracle Solaris 11 release is freshly installed, datalinks are automatically named net0 through netN-1, where N represents the total number of network devices.
On the contrary, if you upgrade from Oracle Solaris 11 Express, the datalinks retain their names that were established prior to the upgrade. These names are either be the default hardware-based names or customized names that the administrator assigned to the datalinks before the upgrade. Further, on these upgraded systems, new network devices that are subsequently added also retain the default hardware-based names rather than receive generic names. This behavior for upgraded systems ensures that no generic names assigned by the OS become mixed with other hardware-based names or customized names assigned by the administrator before the upgrade.
On any system with Oracle Solaris 11, both hardware-based names as well as OS-supplied link names can be replaced by other names that you prefer to use. Typically, the default link names that are assigned by the OS suffice for creating the system’s network configuration. However, to change link names, note the important considerations discussed in the following sections.

I think A
I think B is the correct one, according to this Oracle documentation:

However E looks ok as well, but the “need to be renamed” part is strange… any better idea?
They only ask ‘What happens to the names”, so it’s B, they will stay the same. They may not work/physically exist, but the names will stay the same.
It’s B:
On systems where the Oracle Solaris 11 release is freshly installed, datalinks are automatically named net0 through netN-1, where N represents the total number of network devices.
On the contrary, if you upgrade from Oracle Solaris 11 Express, the datalinks retain their names that were established prior to the upgrade.
