Chapter 7 Review Cisco

Two network engineers are discussing the methods used to forward frames through a switch. What is an important concept related to the cut-through method of switching?

Packets can be relayed with errors when fast-forward switching is used.

Which two issues can cause both runts and giants in Ethernet networks? (Choose two.)

a malfunctioning NIC, half duplex operations

Which part of an Ethernet frame detects errors in the frame?

frame check sequence

Which two functions are performed at the MAC sublayer of the OSI Data Link Layer to facilitate Ethernet communication? (Choose two.)

implements CSMA/CD over legacy shared half-duplex media, integrates Layer 2 flows between 10 Gigabit Ethernet over fiber and 1 Gigabit Ethernet over copper, places information in the Ethernet frame that identifies which network layer protocol is being encapsulated by the frame

What happens when a switch receives a frame and the calculated CRC value is different than the value that is in the FCS field?

the switch drops the frame
