CCNA: Cisco Certified Network Associate — Question 260

What is the same for both copper and fiber interfaces when using SFP modules?

Answer options

• A. They support an inline optical attenuator to enhance signal strength
• B. They accommodate single-mode and multi-mode in a single module
• C. They provide minimal interruption to services by being hot-swappable
• D. They offer reliable bandwidth up to 100 Mbps in half duplex mode

Correct answer: C

Explanation

The correct answer is C because both copper and fiber interfaces with SFP modules can be replaced without shutting down the system, ensuring continuous service. Options A and B are incorrect as they pertain to specific characteristics that do not apply universally to both types of interfaces. Option D is also wrong since bandwidth capabilities can vary significantly between copper and fiber connections.
