The correct answer is that both routes are active and have the same preference value. This is true because the routing table output shows both 10.0.1.0/24 and 10.0.2.0/24 as static routes with a preference of 5, and the presence of the 'A' flag confirms they are active and installed in the forwarding table. In Junos, when you verify static routes in the routing table, the preference value determines route selection; a lower preference is preferred, but equal preferences allow multiple active routes to coexist. On the JNCIA-Junos exam, this concept tests your understanding of route preference and active route flags, often appearing in exhibit-based questions where a common trap is assuming only one static route can be active at a time. Remember the memory tip: “Preference 5 keeps static routes alive” — if the preference matches and the 'A' flag is set, both routes are equally active.
JNCIA-JUNOS Junos OS Fundamentals Practice Question
This JNCIA-JUNOS practice question tests your understanding of junos os fundamentals. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.

Refer to the exhibit. An engineer wants to verify that static routes for 10.0.1.0/24 and 10.0.2.0/24 are present in the routing table. Based on the output, which statement is true?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Both routes are active and have the same preference value.
The output shows both 10.0.1.0/24 and 10.0.2.0/24 as static routes with a preference of 5. Since the preference value is the same and both are listed as active (the 'A' flag is present in the routing table), both routes are installed and active in the forwarding table. In Junos, a static route's default preference is 5, and any route with a lower preference is preferred; here both have equal preference, so they coexist as active routes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Both routes are active and have the same preference value.
Why this is correct
Both are active (marked with '*') and have preference 5.
Related concept
Read the scenario before looking for a memorised answer.
✗
Both routes have a preference of 0.
Why it's wrong here
The preference is 5, as shown in [Static/5].
✗
Only the 10.0.1.0/24 route is active.
Why it's wrong here
Both routes show the '*' indicator, meaning both are active.
✗
Both routes use the same next-hop IP address.
Why it's wrong here
One uses 192.168.1.1, the other uses 192.168.1.2.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume a static route always has a preference of 0 (like a connected route) or that only one static route can be active per destination, but Junos allows multiple static routes with equal preference to be active simultaneously if they have different prefixes.
Trap categories for this question
Command / output trap
The preference is 5, as shown in [Static/5].
Detailed technical explanation
How to think about this question
In Junos, the routing table (inet.0) stores multiple routes to the same destination, but only the active route with the lowest preference is installed into the forwarding table. Static routes default to a preference of 5, which is lower than most dynamic protocols (e.g., OSPF's internal preference is 10), making them highly preferred. The 'A' flag indicates the route is active and used for forwarding; if a route is not active (e.g., due to a withdrawn next hop), it would show a 'P' (pending) or no flag.

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.

What is the correct answer to this question?
The correct answer is: Both routes are active and have the same preference value. — The output shows both 10.0.1.0/24 and 10.0.2.0/24 as static routes with a preference of 5. Since the preference value is the same and both are listed as active (the 'A' flag is present in the routing table), both routes are installed and active in the forwarding table. In Junos, a static route's default preference is 5, and any route with a lower preference is preferred; here both have equal preference, so they coexist as active routes.
