Which two options are fields in an Ethernet frame?(choose two)
- frame check sequence
- source IP address
- destination IP address
Explanation: At the end of each frame there is a Frame Check Sequence (FCS) field. FCS can be analyzed to determine if errors have occurred. FCS uses cyclic redundancy check (CRC) algorithm to detect errors in the transmitted frames. Before sending data, the sending host generates a CRC based on the header and data of that frame. When this frame arrives, the receiving host uses the same algorithm to generate its own CRC and compare them. If they do not match then a CRC error will occur.
The “Type/Length” field is used to indicate the “Type”of the payload (Layer 3 protocol) Which is indicated as a Hexadecimal value.
Note: Ethernet II uses “Type” while the old Ethernet version use “Length”
