- A
Remove the old SFP module, insert the new SFP module, connect the fiber cable, verify interface status with 'show interfaces', and check for errors with 'show interfaces counters errors'.
This sequence follows the correct procedure: first physically replace the module, then connect the cable, then verify the interface is up/up, and finally check for errors to ensure clean operation.
- B
Connect the fiber cable, remove the old SFP module, insert the new SFP module, verify interface status with 'show interfaces', and check for errors with 'show interfaces counters errors'.
This is incorrect because the cable should be disconnected before removing the old module to avoid damage or contamination, and the order of removal and insertion is reversed.
- C
Remove the old SFP module, connect the fiber cable, insert the new SFP module, verify interface status with 'show interfaces', and check for errors with 'show interfaces counters errors'.
This is incorrect because the new module must be inserted before connecting the cable; connecting the cable first can cause strain or misalignment.
- D
Remove the old SFP module, insert the new SFP module, verify interface status with 'show interfaces', connect the fiber cable, and check for errors with 'show interfaces counters errors'.
This is incorrect because the cable must be connected before verifying the interface status; otherwise, the interface will show down/down due to no cable.
CCNA Network Infrastructure and Connectivity Practice Question
This 200-301 practice question tests your understanding of network infrastructure and connectivity. 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.
Drag and drop the following steps into the correct order to replace a faulty fiber optic SFP module and verify the interface on a Cisco IOS-XE switch. Assume the fiber cable is already disconnected from the SFP module.
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
Remove the old SFP module, insert the new SFP module, connect the fiber cable, verify interface status with 'show interfaces', and check for errors with 'show interfaces counters errors'.
The correct order assumes the fiber cable is already disconnected as a safety prerequisite. After removal of the old SFP, insert the new SFP, then reconnect the fiber cable. Finally, verify the interface status with 'show interfaces' and check for errors with 'show interfaces counters errors' to ensure proper operation.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 200-301 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.
