Therefore, the local router does not forward data packets destined for 10.0.3.3. (Multiple Answers) The local router forwards data packets destined for 10.0.3.3 from Ethernet0/0/0. The local router forwards data packet destined for 10.0.2.2 from Ethernet0/0/0. The local router forwards data packets destined for 10.0.12.1 from Ethernet0/0/0.
Which of the following statements about the process of establishing a PPP link are false? (Multiple Answers)** The physical layer is unavailable during the Dead phase. When two communicating devices detect that the physical link between them is activated. PPP enters the Establish phase from the Dead phase. In the Establish phase, the two devices perform LCP negotiation over a PPP link. This is done to negotiate the maximum receive unit (MRU), authentication mode, and magic number. In the Network phase, the two devices perform NCP negotiation. This is done to select and configure network layer protocol and to negotiate network layer parameters. After NCP negotiation is successful, the PPP link maintains the communication state and enters the Terminate phase. The PPP link can work in half-duplex or full-duplex mode.
