When a host sends data to another IP network, which actions can occur during encapsulation?Select all correct answers.The destination IP address is always replaced by the gateway's IP addressThe host creates an IP packet with source and destination IP addressesThe frame can use the default gateway's MAC address as destinationThe application destination port is replaced by a MAC addressThe host builds a local Layer 2 frame for the next hopOSI & TCP/IP ModelsEasy1 mark(s)14. Which statements correctly describe TCP?Select all correct answers.It is connection-orientedIt provides sequencing and acknowledgmentsIt uses MAC addresses to identify applicationsIt can retransmit lost dataIt always operates without a handshakeOSI & TCP/IP ModelsMedium1 mark(s)15.
