You administer a server running a global zone with no virtual networking. Consider the following configuration:
Which is a valid IPMP configuration for this server?
A.
net0 and net1 must be configured into an IPMP group, net2 can be configured into its own IPMP group, and
net0 or net1 can be configured as a standby interface.
B.
net0 and net1 must be configured into one IPMP group, net2 and net3 must be configured into a second
IPMP group, and all interfaces can be configured for link detection.
C.
net1 and net2 must be configured into an IPMP group, net0 can be configured into its own IPMP group, and
net3 can be configured as a standby interface.
D.
net0 and net2 must be configured into an IPMP group, net0 can be configured into its own IPMP group, and
net3 can be configured as a standby interface.
Explanation:
Must be in the same network range (see * below).
Different speeds are fine (see ** below).
* An IP multipathing group, or IPMP group, consists of one or more physical interfaces on the same system that
are configured with the same IPMP group name. All interfaces in the IPMP group must be connected to the
same IP link (A, not B, not C, Not D).
** The same (non-null) character string IPMP group name identifies all interfaces in the group. You can place
interfaces from NICs of different speeds within the same IPMP group, as long as the NICs are of the same
type. For example, you can configure the interfaces of 100-megabit Ethernet NICs and the interfaces of one
gigabit Ethernet NICs in the same group. As another example, suppose you have two 100-megabit Ethernet
NICs. You can configure one of the interfaces down to 10 megabits and still place the two interfaces into the
same IPMP group.
