builds the table using unknown source MAC addresses from received frames

builds the table using unknown destination MAC addresses from received frames

time stamps the entries for each address

time stamps the BPDU of each frame received

maps switch port numbers with the associated MAC address

maps switch port numbers with the associated network address

2 Which of the following messages are sent from a DHCP server to a client during a successful configuration process? (Choose two.)

DHCPDISCOVER

DHCPOFFER

DHCPREQUEST

DHCPACK

3 What are the effects of LAN segmentation using a switch? (Choose three.)

dedicated bandwidth between source and destinations

enlarged collision domains

decreased broadcast domains

increased number of collision domains

increased latency in the network

4 Which of the following EIGRP functions is the responsibility of the IP protocol-dependent module (PDM)? (Choose three.)

the calculation of successor and feasible successor routes for IP and IPX traffic

the notification of DUAL when IP routing information is received

the communication of information about IP routes with neighbor routers

the maintenance of the IP routing table

the exchange of hello packets with other IP-enabled routers

the insertion of lowest cost paths into the routing table

5 Which functions are carried out by switches and bridges when building the CAM tables? (Choose three.)

builds the table using unknown source MAC addresses from received frames

builds the table using unknown destination MAC addresses from received frames

time stamps the entries for each address

6 What is the term for the cabling that connects the customer premises equipment to the CO switch?

demarc

local loop

final mile

DTE

7 An administrator has an older 1900 switch located on the edge of the network. What can the network administrator do to ensure that it does not become the root bridge of the spanning-tree network?

decrease the BPDU hello timer update on the 1900

assign the highest IP address to the switch that should be the root

assign the lowest IP address to new root bridge

assign the lowest priority to the switch that should be the root

assign the highest priority to the new root bridge

decrease the BID on the 1900 switch
