30	Based on the graphic above, which of the following occurs as each host system comes on line in the topology? The switch sends its MAC address to each host. The switch adds MAC address to the bridge table as each host sends a frame. Each host exchanges MAC addresses with each other. The switch listens for data traffic to block since the switch lacks an IP address.
31	Two peer hosts are exchanging data using TFTP. During the current session, a datagram fails to arrive at the destination. Which statement is true regarding the retransmission of the datagram? Datagram retransmission requires user authentication. Datagram retransmission is controlled by the application. Datagram retransmission relies on the acknowledgements at transport layer. Datagram retransmission occurs when the retransmission timer expires in the source host.

The switch reads the source MAC address on incoming frames and records it in CAM. The switch reads the destination MAC address on incoming frames and records it in CAM. If a switch port is full duplex, the switch reads both the source and destination MAC addresses on incoming frames and records them in CAM.

40	Refer to the exhibit. A network associate needs to establish an Ethernet connection between Host A and Host B. However, the distance between the two hosts is further than the cabling standards allow. Which two devices that operate at the physical layer of the OSI can be used to allow Host A and Host B to communicate? (Choose two.) switch hub bridge router repeater
41	Refer to the exhibit. Workstation 1 pings the Fa0/1 interface of Router 1. Which MAC address will workstation 1 obtain during the ARP request for this communication? 00-06-5B-88-DF-C3 00-B0-D0-7F-F7-46 00-0F-24-85-75-C0 00-0B-E5-64-BD-44 00-08-A3-B6-CE-02 00-08-A3-B6-CE-03

The IP address of Host A is incorrect. The subnet mask of Host A is incorrect. The default gateway of Host A is incorrect. Host A is properly configured. Some other problem exists in the internetwork.
