Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Only the static route with the highest preference value is installed into the FIB.
Why it's wrong here
Higher preference values mean less preferred routes in Junos.
- ✓
Only the static route with the lowest preference value is installed into the FIB.
Why this is correct
Junos selects the route with the lowest preference value as the active route and installs it into the FIB.
- ✗
All static routes are installed into the FIB, and traffic is automatically load-balanced across them.
Why it's wrong here
Load balancing requires explicit configuration using a policy and the load-balance action.
- ✗
All valid static routes are installed into the FIB regardless of preference values.
Why it's wrong here
Only the active route is installed by default, unless per-packet load balancing is configured.
