Cards in this deck (13)
- 1What is the 4th field of an Ethernet frame?Ethertype
- 2What does the EtherType field do?Identifies the upper layer protocol encapsulated in the Data field
- 3What is the EtherType hex code for IPv4?0x800
(or 0x0800) - 4What is the EtherType hex code for IPv6?0x86DD
- 5What is the EtherType hex code for ARP?0x806
(or 0x0806) - 6How many bytes can the Data field contain?46 - 1500 bytes
- 7What does FCS stand for?Frame Check Sequence
- 8How many bytes is a MAC address?6 bytes
- 9How many bytes is the Preamble field?8 bytes
- 10What is the last byte of the Preamble field?SFD or Start Frame Delimiter
- 11How many bytes is the FCS?4 bytes
- 12How does the FCS detect errors in a frame?The FCS field includes the results of a CRC from the sending device.
