ITN 07.04 Switch Speeds and Forwarding Methods

Front

What type of switching involves the switch receiving the entire frame, computing the CRC, and forwarding the frame out of the correct port if the CRC is valid?

Back

Store-and-forward switching

Front

What type of switching forwards the frame before it is entirely received, requiring at least the destination address to be read?

Back

Cut-through switching

Front

Which frame forwarding method is used for quality of service (QoS) analysis on converged networks where frame classification for traffic prioritization is necessary?

Back

Store-and-forward switching

Front

In _______________ the switch acts upon the data as soon as it is received, even if the transmission is not complete.

Back

Cut-through switching

Front

In which forwarding method does the switch NOT perform any error checking before forwarding the frame?
Options: Store-and-forward switching, Cut-through switching, Fragment-free switching

Back

Cut-through switching

Front

Which variant of cut-through switching offers the lowest level of latency?

Back

Fast-forward switching

Front

In which frame forwarding method does the switch immediately forward a packet after reading the destination address in the first six bytes of the frame?

Back

Fast-forward switching

Front

In which frame forwarding method does the switch store the first 64 bytes of the frame before forwarding?

Back

Fragment-free switching

Front

In which frame forwarding method does the switch perform a small error check on the first 64 bytes of the frame to ensure that a collision has not occurred before forwarding the frame?

Back

Fragment-free switching

Front

Which of the following frame forwarding methods has the lowest latency?
Options:
Cut-through switching,
Store-and-forward switching

Back

Cut-through switching
