question 19
what is one advantage of using the cut - through switching method instead of the store - and - forward switching method?
makes a fast forwarding decision based on the source mac address of the frame
has a positive impact on bandwidth by dropping most of the invalid frames
has a lower latency appropriate for high - performance computing applications
provides the flexibility to support any mix of ethernet speeds

Explanation:

Cut - through switching starts forwarding frames as soon as it has read the destination MAC address, reducing latency compared to store - and - forward which reads the entire frame before forwarding. High - performance computing applications benefit from lower latency. It doesn't make decisions based on source MAC for forwarding, doesn't drop most invalid frames like store - and - forward (which checks CRC), and doesn't have the main advantage of supporting any mix of Ethernet speeds.

Answer:

has a lower latency appropriate for high - performance computing applications
