Question 308 of 514
Operational Monitoring and MaintenancehardMultiple SelectObjective-mapped

Quick Answer

The answer is the `show route` command and the `show route table inet.0` command, as both display the IPv4 unicast routing table in Junos. The `show route` command without any filter defaults to showing all routes in the primary IPv4 unicast table, which is `inet.0`, while `show route table inet.0` explicitly targets that same table, making either command valid for viewing IPv4 unicast routes. On the JNCIA-Junos exam, this tests your understanding of Junos routing table structure and default behavior—a common trap is assuming you must always specify a table name, but `show route` alone already shows `inet.0`. Remember that `inet.0` is the default for IPv4 unicast, so if you ever need to confirm you are looking at the right table, use `show route table inet.0` for clarity. A helpful memory tip: think of “inet.0” as the “home base” for all IPv4 unicast routes—when in doubt, just type `show route` and you are already there.

JNCIA-JUNOS Operational Monitoring and Maintenance Practice Question

This JNCIA-JUNOS practice question tests your understanding of operational monitoring and maintenance. 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.

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

show route table inet.0

Option B is correct because `show route table inet.0` explicitly displays the IPv4 unicast routing table (inet.0) in Junos. Option D is correct because `show route` without any filter defaults to showing all routes in the inet.0 table, which is the primary IPv4 unicast routing table.

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.

  • show route protocol static

    Why it's wrong here

    This command shows only static routes in the routing table, not all IPv4 unicast routes. It is too specific.

  • show route table inet.0

    Why this is correct

    'show route table inet.0' explicitly displays the IPv4 unicast routing table. This is equivalent to 'show route' but more specific.

    Related concept

    Read the scenario before looking for a memorised answer.

  • show forwarding-table

    Why it's wrong here

    'show forwarding-table' displays the forwarding table, which is derived from the routing table but includes next-hop information and is used for packet forwarding, not the routing table itself.

  • show route

    Why this is correct

    'show route' displays the default routing table (inet.0 for IPv4 unicast) by default, showing all IPv4 unicast routes.

    Related concept

    Read the scenario before looking for a memorised answer.

  • show route table inet6.0

    Why it's wrong here

    This command displays the IPv6 unicast routing table, not IPv4. It is irrelevant for IPv4.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse the routing table (`show route`) with the forwarding table (`show forwarding-table`), or assume a specific protocol filter like `protocol static` shows all routes, when in fact it only shows routes learned via that protocol.

Trap categories for this question

  • Command / output trap

    This command shows only static routes in the routing table, not all IPv4 unicast routes. It is too specific.

Detailed technical explanation

How to think about this question

In Junos, the routing table (inet.0) stores all learned routes (direct, static, OSPF, BGP, etc.) and is used for route selection via the route preference and metric. The forwarding table is a separate, optimized copy used by the Packet Forwarding Engine (PFE) for actual packet forwarding. The `show route` command without a table argument defaults to inet.0, making it the most common way to view IPv4 unicast routes in production environments.

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.
