That’s a really bad mismatch

Which of these are commonly seen when the speed and duplex is mismatched on an Ethernet link? Pick two.

A) You’ll have poor throughput

B) Only half of the data will be received

C) You won’t see a link light

D) File transfers will randomly be corrupted

E) Some web sites will be accessible and others will not

F) You shouldn’t really wear those stripes with those polka dots

The answer: A) You’ll have poor throughput and C) You won’t see a link light

If a link has mismatched duplex, you’ll see low throughput when you transfer information between devices. A duplex mismatch doesn’t corrupt data and all of the data will still be received, since the IP headers and applications will perform error-checking. You can still visit any web site, but the throughput will certainly be affected.

If the speed is mismatched, the link will not be active and you won’t get any traffic to pass between the devices.

The network adapter configuration is the first step when connecting to the network. In this video, you’ll learn how to set adapter configuration settings and configure quality of service (QoS) options.
