- A
Insert the SFP module into the port while the switch is powered on
This is the correct sequence. Powering down ensures safety when handling the SFP module. After inserting the SFP, the fiber cable is connected, then the switch is powered up, and finally the interface status is verified.
- B
Connect the fiber optic cable to the SFP module
This is incorrect because inserting an SFP module while the switch is powered on can cause electrical damage or improper seating. Powering down should occur before insertion.
- C
Verify the interface status using 'show interfaces status'
This is incorrect because the fiber cable should be connected after the SFP module is securely inserted into the port. Connecting the cable first can strain the connector or cause improper alignment.
- D
Power down the switch, connect the fiber optic cable directly to the switch port without an SFP module, power up the switch, and verify the interface status.
This is incorrect because fiber optic connections require an SFP module; you cannot connect a fiber cable directly to a standard Ethernet port. The SFP module must be installed first.
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 install a new fiber optic cable and SFP module on a Cisco switch, then verify the interface status.

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
Insert the SFP module into the port while the switch is powered on
The correct procedure for installing a fiber optic cable and SFP module on a modern Cisco switch is to insert the SFP module into the port while the switch is powered on, as most Cisco switches support hot-swapping of SFP modules to minimize network downtime. Then, connect the fiber optic cable to the SFP module, ensuring proper alignment and locking. Finally, verify the interface status using 'show interfaces status' to confirm the link is up and operational. Powering down the switch is unnecessary and contradicts hot-swappable design, while connecting the cable before inserting the SFP or skipping the SFP module entirely are incorrect because the switch port requires an SFP to convert electrical signals to optical.
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.
