A network administrator is configuring a mixed network environment with both high-speed corporate connections and smaller links for remote offices. If the main goal is to minimize packet breakup, which MTU setting on the routers should be considered the BEST?
You selected this option
Set an average size based on all connected link capacities
You selected this option
Maintain default settings for each connection type without adjustments
You selected this option
Increase all link sizes to the maximum allowed by the high-speed corporate connections
You selected this option
Conform all settings to the smallest link capacity to prevent packet segmentation
Setting the MTU to match the smallest allowed data packet size in the network minimizes fragmentation. In settings with a combination of higher and lower capacity links, selecting the MTU of the smaller links as the standard avoids fragmentation that could occur if packets allowed by larger capacity links are too big to be handled by the smaller links without breaking them up.
