CCNA Network Infrastructure and Connectivity Practice Question
Drag and drop the following steps into the correct order to isolate CRC errors, duplex mismatches, and flapping on a Cisco IOS-XE interface.
⚠ Common exam trap
Do not confuse the order of enabling debugs and monitoring logs. Debuffs must be enabled before you can monitor the debug output. Also, configuration mode is typically entered first to set up logging parameters or debug conditions.
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
✓
Enter configuration mode, enable debugs, monitor logs, analyze data, apply fixes and verify.
First enter configuration mode, then enable debugs to capture errors, monitor logs, analyze the data, and finally apply fixes and verify.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enter configuration mode, enable debugs, monitor logs, analyze data, apply fixes and verify.
Why this is correct
This is the correct order: first enter configuration mode to prepare the device, then enable debugs to capture errors, monitor logs to observe real-time events, analyze the data to identify root causes, and finally apply fixes and verify the solution.
- ✗
Enable debugs, enter configuration mode, monitor logs, analyze data, apply fixes and verify.
Why it's wrong here
Initiating debug sessions before entering configuration mode is unsafe because you have not yet set up logging buffers, timestamps, or access-control restrictions to prevent debug output from overwhelming the device and console. Without 'terminal monitor' on vty lines or proper logging configuration, debug messages may not be captured or may flood the CPU. Configuration mode provides the context to configure these parameters before enabling the intrusive debug process.
- ✗
Monitor logs, enter configuration mode, enable debugs, analyze data, apply fixes and verify.
Why it's wrong here
Monitoring logs before enabling debug provides only routine severity-level events (informational through critical) and cannot show the detailed debug-level messages needed for root-cause analysis. You are also not in configuration mode to adjust logging options, such as buffered logging or setting the logging severity. This sequence wastes time reviewing incomplete information rather than first preparing the device and enabling the diagnostic source.
- ✗
Enter configuration mode, monitor logs, enable debugs, analyze data, apply fixes and verify.
Why it's wrong here
Although configuration mode is the correct starting point, monitoring logs before enabling debugs means you are observing an inactive debug stream; nothing new will appear because debug messages are only generated after a 'debug' command is issued. Consequently, you will see no debug-level output, and the analysis step will be based on stale or incomplete data. The order must be: configure, enable debug, then monitor the resulting output.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.

Why this is correct
This is the correct order: first enter configuration mode to prepare the device, then enable debugs to capture errors, monitor logs to observe real-time events, analyze the data to identify root causes, and finally apply fixes and verify the solution.
✗Enable debugs, enter configuration mode, monitor logs, analyze data, apply fixes and verify.Wrong answer — click to see why▾
Why this is wrong here
The order is wrong: debugs should be enabled after entering configuration mode, not before.
Why candidates choose this
Candidates might think debugging is the first step, but configuration mode is needed to enable debugs properly.
✗Monitor logs, enter configuration mode, enable debugs, analyze data, apply fixes and verify.Wrong answer — click to see why▾
Why this is wrong here
Monitoring logs before enabling debugs means you miss the debug messages; the sequence is out of order.
Why candidates choose this
Candidates might think monitoring logs is the first step, but debugs must be enabled first to generate the relevant log entries.
✗Enter configuration mode, monitor logs, enable debugs, analyze data, apply fixes and verify.Wrong answer — click to see why▾
Why this is wrong here
The order is wrong: debugs should be enabled before monitoring logs to capture debug output.
Why candidates choose this
Candidates might think monitoring logs is a passive step that can be done anytime, but without debugs, critical error details may be missing.
