CompTIA Network+ (N10-009) — Question 103

A research facility is expecting to see an exponential increase in global network traffic in the near future. The offices are equipped with 2.5Gbps fiber connections from the ISP, but the facility is currently only utilizing 1Gbps connections. Which of the following would need to be configured in order to use the ISP's connection speed?

Answer options

• A. 802.1Q tagging
• B. Network address translation
• C. Port duplex
• D. Link aggregation

Correct answer: D

Explanation

Link aggregation is necessary to combine multiple network connections to increase throughput and utilize the full 2.5Gbps speed from the ISP. The other options do not address the need for increased bandwidth; 802.1Q tagging is for VLANs, Network Address Translation manages IP addresses, and Port duplex refers to the communication mode (half or full), which does not affect overall connection speed.
