CompTIA Network+ (N10-007) — Question 372

Ann, a customer, recently upgraded her SOHO Internet to gigabit fiber from cable. She was previously getting speeds around 75Mbps down and 25Mbps up. After the upgrade, Ann runs a speed test on her desktop and gets results of 1000Mbps down and 100Mbps up. A technician connects directly to the router and sees the correct 1000Mbps speeds. Which of the following is MOST likely the cause? (Choose two.)

Answer options

• A. All ports should be configured for full duplex.
• B. There is a 10/100 switch on the network.
• C. The connections are using Cat 5 cable.
• D. The connections are using Cat 6 cable.
• E. There is a transceiver mismatch at the fiber termination point.
• F. Signal attenuation on the new fiber has reached the upper limits.

Correct answer: A, C

Explanation

The correct answers are A and C. Configuring all ports for full duplex is essential for maximizing speed, and if the network is using Cat 5 cable, it can only support up to 100Mbps, which would limit performance. The other options, while they may present issues, do not directly explain the observed speeds after the upgrade.
