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?

Question

Options

• Anet0 and net1 must be configured into an IPMP group, net2 can be configured into its own IPMP
• Bnet0 and net1 must be configured into one IPMP group, net2 and net3 must be configured into a
• Cnet1 and net2 must be configured into an IPMP group, net0 can be configured into its own IPMP
• Dnet0 and net2 must be configured into an IPMP group, net0 can be configured into its own IPMP

Explanation

Option D is correct because in IPMP, interfaces sharing the same IP link (subnet) must be placed in the same IPMP group - you cannot leave two same-link interfaces ungrouped. Based on the referenced configuration, net0 and net2 reside on the same physical link, making their grouping mandatory, while net1 (on a different link) can legitimately form a single-member IPMP group on its own.

Options A and C are wrong because they pair interfaces (net0+net1 or net1+net2) that belong to different subnets/links - IPMP groups require all members to share the same IP link, so cross-subnet groupings are invalid. Option B is wrong because it forces net2 and net3 into a group when the configuration does not place them on the same link, and grouping unrelated interfaces violates IPMP's same-link requirement.

Memory tip: Think of IPMP as a "same street" rule - only interfaces living on the same network street (same IP link/subnet) can share a group. If two interfaces are on the same subnet, they must be grouped together; a lone interface on its own subnet can always form a solo group.
