Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
set protocols ospf area 0.0.0.0 interface em0.0 passive

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 ospf area 0.0.0.0 interface em0.0 silent
Why it's wrong here
'silent' is not a Junos OSPF keyword.
- ✗
set protocols ospf passive-interface em0.0
Why it's wrong here
Passive interfaces are configured under the specific area interface hierarchy.
- ✗
set protocols ospf area 0.0.0.0 interface em0.0 disable-hellos
Why it's wrong here
This command does not exist in Junos.
- ✓
set protocols ospf area 0.0.0.0 interface em0.0 passive
Why this is correct
The 'passive' keyword configures the OSPF interface as passive.
