Network Troubleshooting

A new backup system takes too long to copy files to the new SAN each night. A network administrator makes a simple change to the network and the devices to decrease backup times. Which of the following does the network administrator change?

Explanation

Increasing the MTU (Maximum Transmission Unit) enables the use of jumbo frames, typically 9000 bytes instead of the standard 1500 bytes. This reduces the number of packets required to transfer the same amount of data, decreasing CPU overhead and significantly improving throughput—especially beneficial for backup operations. QoS prioritizes traffic, SDN is an architectural approach, VXLAN creates overlays, and TTL controls hop count.
