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 routing-options multicast pim-enable
Why it's wrong here
This is an invalid path in Junos.
- ✗
set protocols multicast enable
Why it's wrong here
Protocols multicast does not exist as a top-level hierarchy.
- ✓
set protocols pim interface all
Why this is correct
Enabling PIM on 'interface all' turns on PIM sparse-mode across all router interfaces.
- ✗
set protocols pim interface all mode sparse
Why it's wrong here
PIM sparse-mode is the default mode in Junos, so 'mode sparse' is not a valid syntax; simply enabling it on the interface is sufficient.
