Correct Answer: C
ccna test voucher cost.9.2.2 PC-A Opens a Session to PC-BThis section demonstrates how PC-A opens a Telnet session to PC-B, including how to use DNS, how to establish a TCP connection, and how to remove a TCP connection. 1.1. PC-A resolves PC-B's nameAssume that PC-A does not know PC-B's IP address, but knows its name. With this in mind, the user of PC-A executes the following command at the Windows command line.C: \> telnetPC-BSince the name is specified, it must be resolved to an IP address using DNS. pc.A creates a DNS query for the name PC-B and sends it to the DNS server. Note that since the DNS server is located in another subnet, it must first forward this frame to Router A,so the destination MAC address must be the MAC address of Router A. Since PC-A does not know the MAC address of Router A, it must use ARP to request the MAC address associated with 10.0.1.2 (the default gateway). The source MAC address for this ARP request is the MAC address of PC.A. The destination MAC address is the broadcast address, so Switch A will flood. Router A will respond to the ARP request with the correct IP address (in addition, it will add the IP address and MAC address of PC-A to its local ARP table); in this Ethernet frame, the source MAC address is the MAC address of Router A and the destination address is the MAC address of PC.A. The switch will perform the learn function and add Router A's MAC address 0000.1111.BBBB (the router's MAC address) to the CAM table. At this point, the switch learns all the MAC addresses in the broadcast domain to which it belongs and is able to intelligently forward unicast frames without resorting to flooding.Table 9.1 DNS PDUsOnce PC.A receives the ARP answer, it can create a DNS query and forward it to Router A. PDU 1 of Table 9.1 shows part of the frame header, IP packet header, and UDP data segment header for this Ethernet frame. Information about layers 3 and 4 is stored in the local connection table, so PC-A knows how to handle DNS responses.Practical Experience To view the PC's local connection table, use the command netstatoWhen sending IP packets over the network, as the packet travels through the Layer 3 network, except for the TOS and TTL fields
