- A
A static route with a next-hop of an IP address requires that the next-hop be reachable.
The route becomes active only if the next-hop is reachable in the routing table.
- B
Static routes can be configured with a qualified-next-hop to provide conditional routing.
Qualified next-hops allow a static route to have a fallback next-hop that is used only if the primary next-hop is unreachable.
- C
A static route with a next-hop of an interface will be active even if the interface is down.
Why wrong: If the interface is down, the route is not active.
- D
A static route with a preference of 10 is preferred over a static route with a preference of 5.
Why wrong: A lower preference number indicates a more preferred route.
- E
Static routes cannot be used for load balancing.
Why wrong: Static routes can be used for equal-cost load balancing by configuring multiple next-hops.
JNCIA-JUNOS Routing Fundamentals Practice Question
This JNCIA-JUNOS practice question tests your understanding of routing fundamentals. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which two statements are true about static routes on Juniper devices? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
A static route with a next-hop of an IP address requires that the next-hop be reachable.
Option A is correct because a static route with a next-hop IP address requires the next-hop to be reachable via a connected or active route in the routing table; otherwise, the route is not installed. This ensures that the router does not forward traffic to an unreachable destination, maintaining routing integrity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume a static route with a next-hop of an interface remains active regardless of interface state, but Junos strictly requires the interface to be up for the route to be installed.
Detailed technical explanation
How to think about this question
In Junos, static routes with a next-hop of an interface (e.g., ge-0/0/0) are installed as directly connected routes and rely on the interface's link state; if the interface goes down, the route is withdrawn. The qualified-next-hop feature allows you to specify multiple next-hops with different preferences, enabling conditional routing where a backup next-hop is used only if the primary fails. This is useful in scenarios like dual-homed connections where you want to prefer one link over another without dynamic routing protocols.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the JNCIA-JUNOS exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
