200-301 Question 68
Single answerA network administrator is tasked with connecting a Cisco switch to a new server. The server has a 10 Gbps NIC (Network Interface Card), and the distance between the switch and server is 50 meters within the data center. Which cable and physical interface should the administrator use to ensure optimal performance?
- A
Cat5e Ethernet cable with an RJ45 connector
- B
Cat6a Ethernet cable with an RJ45 connector
- C
Single-mode fiber optic cable with an LC connector
- D
Twinax cable with SFP+ connectors
Show answer and explanation
Correct answer: B
Explanation
Cat6a Ethernet cable with an RJ45 connector is the appropriate choice for connecting a server with a 10 Gbps NIC to a switch over a medium distance of 50 meters in a data center. It supports the required speed and distance while being cost-effective compared to fiber optic solutions.
- A. Incorrect.
Cat5e cables are limited to 1 Gbps speeds and are not suitable for the 10 Gbps NIC in the server.
- B. Correct.
Cat6a cables support up to 10 Gbps over distances up to 100 meters, making this a suitable choice for the 50-meter connection within the data center.
- C. Incorrect.
Single-mode fiber optic cables are typically used for long-distance connections, often exceeding hundreds of meters or kilometers, and would be unnecessary for a 50-meter connection.
- D. Incorrect.
Twinax cables with SFP+ connectors are commonly used for short-distance high-speed connections (up to 10 meters), which makes them unsuitable for the 50-meter distance in this scenario.
