Question

question 7
which two fields or features does ethernet examine to determine if a received frame is passed to the data link layer or discarded by the nic? (choose two.)
source mac address
frame check sequence
minimum frame size
auto - mdix
cef

Explanation:

Ethernet uses the Frame Check Sequence (FCS) to check for errors in the frame. If the FCS calculation doesn't match, the frame is discarded. Also, if the frame is smaller than the minimum frame size for the Ethernet - standard (64 bytes for 10/100/1000 Mbps Ethernet), it is considered a runt frame and discarded. The source MAC address is not used for this decision - making process for discarding frames. Auto - MDIX is related to cable connection and CEF (Cisco Express Forwarding) is a Cisco - specific switching mechanism.

Answer:

B. Frame Check Sequence
C. minimum frame size
