is ccna open book.1. the Ao transport layer is closely associated with end-to-end communication and provides multiplexing via sockets.2. co workstations can detect conflicts using the CSMA/CD mechanism. In case of a conflict, each workstation waits for a randomly specified period of time before retransmitting data, the duration of which is called backofftime. o3. o AoHUBs and Repeaters can only regenerate signals and send them outbound from all ports.4. the Ao MAC address table holds the correspondence between the MAC address and the physical port of the switch to which the host with that MAC address is connected.5. A and B. The wireless LAN controller provides wireless workstation authentication functions, QoS functions, security management functions, and other management service functions.6. the Ao receiver host identifies different slices belonging to the same original IP packet based on the value of the identification field.7. Ao network device learns the MAC address of another device with the help of Address Resolution Protocol (ARP) if its IP address is known8. the AoDNS resolver issues a recursive query to the locally configured DNS server. 9. into. A /25 network will reserve 7 bits for the host address space and its host count is calculated as 27.2 = 126. ofThe reason for subtracting two addresses is that one address is the network ID, and the other address is the broadcast address. B./64 networks have 64 bits available for assigning IPv6 addresses to hosts.H. AoSLAAC is a protocol used by hosts to generate IPv6 addresses. 12.
