JN0-106 Operational Monitoring and Maintenance Practice Question
A junior engineer needs to collect a snapshot of the current system state, including routing tables, interfaces, and configuration, for a support ticket. Which command achieves this?
⚠ Common exam trap
Watch out — candidates often confuse individual show commands (like 'show route' or 'show interfaces') with the all-in-one 'request support information' command, failing to recognize that only the latter captures the full system state required for a support ticket.
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
✓
request support information
The 'request support information' command is the correct choice because it collects a comprehensive snapshot of the current system state, including routing tables, interface details, configuration, logs, and other operational data into a single archive file. This is specifically designed for support tickets, as it bundles all relevant diagnostic information in one step, unlike individual show commands that only capture partial data.
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 configuration
Why it's wrong here
This command displays the candidate or active configuration in Junos, showing only static device settings such as interfaces, protocols, and policies. It does not capture operational state, current system status, logs, or dynamic routing information, which are often necessary for full troubleshooting. As a result, it provides an incomplete snapshot of the system's current condition, making it unsuitable for comprehensive diagnostic data collection.
- ✗
show interfaces
Why it's wrong here
This command provides detailed operational information about interfaces, including traffic statistics, error counters, and link status. However, it is limited to interface-specific data and does not gather system-wide information like routing tables, logs, processes, or configuration. For a broad snapshot of the system's health, this command is too narrow and would miss critical components of the overall state.
- ✓
request support information
Why this is correct
This is a Junos operational command that automatically collects a comprehensive set of system data, including configurations, interface statistics, routing tables, logs, system processes, and other diagnostic information into a single archive. It is designed specifically for troubleshooting and for providing a complete snapshot to Juniper support or for offline analysis. This one command aggregates far more data than any individual show command, making it the correct choice for a full system snapshot.
- ✗
show route
Why it's wrong here
This command displays the routing table, including active routes, next hops, and protocol-specific entries. While useful for network reachability analysis, it only covers the routing plane and not the overall system state such as interfaces, logs, or configuration. Thus, it gives a narrow view that cannot serve as a comprehensive system snapshot.
