Which of the following OSI model layers are responsible for handling packets from the sources to the destination and checking for errors? (Choose two.)
C. Data link
D. Network
Layers responsible for handling packets from source to destination and checking for errors in the OSI model are:
C. Data link: This layer is responsible for framing packets, error detection, and handling the access to the physical network medium. It includes the logical link control (LLC) sublayer and the media access control (MAC) sublayer.
D. Network: This layer is responsible for routing packets between different networks, logical addressing, and providing services such as fragmentation and error handling. It includes IP (Internet Protocol) in the case of the TCP/IP protocol suite.
Therefore, the correct answers are C. Data link and D. Network.
Isn't it ment to be data link and transport layer ?
data link layer picks up CRC errors and transport layer protcol TCP would pick up incorrect orders of packets, missing packets + re-request the packet...?
Maybe not, but I'm kind of a fan of including the session layer in this.
