Answers:
[1] d) Physical
[2] b) TCP
[3] a) IP
[4] b) Error reporting
[5] b) 1500 bytes
[6] d) Guaranteeing reliable data transfer
[7] a) Data transfer
[8] a) Resolving IP addresses to MAC addresses
[9] a) Managing multicast group membership
[10] a) Managing and monitoring network devices
Reasoning:
[1] The TCP/IP model has 4 layers: Application, Transport, Internet, and Link. Physical layer is not a layer in the TCP/IP model.
[2] TCP provides reliable data transfer in the Transport layer of the TCP/IP model by using techniques such as flow control and error checking.
[3] IP provides logical addressing in the Network layer of the TCP/IP model by using IP addresses.
[4] ICMP is used for error reporting, such as informing the sender of a broken connection or a full buffer.
[5] The default MTU of an Ethernet network is 1500 bytes.
[6] TCP guarantees reliable data transfer by using techniques such as flow control, error checking, and retransmission of lost packets.
[7] UDP does not guarantee reliable data transfer, it is used for data transfer.
[8] ARP is used to resolve IP addresses to MAC addresses on a local network.
[9] IGMP is used for managing multicast group membership on a network.
[10] SNMP is used for managing and monitoring network devices
