How do you add a test address to an IPMP group?

Question

Options

• AUse ipadm create-addr to add the address to a member interface.
• BUse ipadm create-addr to add the address to the IPMP interface.
• CUse ipadm create-ip to add an address to a member interface.
• DUse ipadm create-ip to add an address to the IPMP interface.

• C

• D

Explanation

In Oracle Solaris IPMP, test addresses are used for link/path failure detection, and they must be assigned to member interfaces (the physical NICs in the group) - not to the IPMP interface itself. ipadm create-addr is the correct subcommand for assigning an IP address to an interface, making A the only correct choice.

Why the distractors fail:

• B is wrong on placement: the IPMP interface holds data addresses, not test addresses. Putting a test address there defeats its purpose of probing the underlying physical link.
• C uses the wrong subcommand: ipadm create-ip creates an IP interface object (the IP layer over a datalink) - it does not assign an address.
• D is wrong on both counts: wrong subcommand (create-ip) and wrong target (IPMP interface instead of member interface).

Memory tip: Think "Test → Member, Data → IPMP" - test addresses live on members so IPMP can monitor each physical link individually. And remember, create-addr = address, create-ip = interface object; you need addr to actually assign an IP.
