Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
set protocols pim interface irb.10 igmp-version 3
Why it's wrong here
IGMP configurations are defined under protocols igmp, although PIM may interact with IGMP states.
- ✗
set interfaces irb.10 family inet igmp-version v3
Why it's wrong here
IGMP protocol configurations are maintained under protocols igmp, not directly under the interface family inet stanza.
- ✓
set protocols igmp interface irb.10 version 3
Why this is correct
The 'version 3' statement under protocols igmp interface explicitly sets the IGMP version to 3.
- ✗
set routing-options multicast igmp-version 3
Why it's wrong here
Global multicast routing-options do not contain the interface-specific IGMP version command.
