You display the IP Interface information with ipmpstat - i. Which two characteristics are indicated by characters that may be included in the FLAGS column?

Question

Options

• Adefault route
• BIP forwarding enabled
• Callocated to global zone
• Dunusable due to being inactive
• Enominated to send/receive IPv4 multicast for its IPMP group

• A
  7% (2)
• C
  4% (1)
• D
  89% (24)

Explanation

When using ipmpstat -i on Oracle Solaris, the FLAGS column uses single-character codes to represent per-interface states. The i flag marks an interface as inactive, meaning it is unusable by the IPMP group - directly corresponding to option D. The m flag identifies the interface nominated to handle IPv4 multicast traffic for its IPMP group - corresponding to option E. These are both per-interface behavioral states that IPMP tracks and surfaces in this specific column.

Why the distractors are wrong:

• A (default route): Default route information is not surfaced as a FLAGS character in ipmpstat -i; routing is managed separately via route or netstat -r.
• B (IP forwarding): IP forwarding is a system-wide or per-address-family setting visible via ipadm show-prop, not a per-interface IPMP flag.
• C (allocated to global zone): Zone assignment is a separate attribute tracked by dladm or ipadm, not encoded in ipmpstat FLAGS.

Memory tip: Think of the two flags as the "Inactive Multicast" pair - i = interface is down/unusable, m = multicast duty assigned. If you remember "IM" you'll recall both correct answers (D and E) instantly on exam day.
