CompTIA Network+ (N10-009) — Question 414

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?

Answer options

• A. QoS
• B. SDN
• C. MTU
• D. VXLAN
• E. TTL

Correct answer: C

Explanation

The correct answer is C, MTU, because adjusting the Maximum Transmission Unit can optimize how much data is sent in each packet, leading to more efficient transfers. The other options, such as QoS and SDN, relate to network management and control but do not directly influence the size of data packets being transmitted, which is crucial for backup speeds.
