(Choose three.)
-- 192.168.18.38
-- 192.168.18.48

74. Refer to the exhibit. What two facts can be determined from the information that is given? (Choose two.)
-- This exchange is part of the three-way handshake.
-- The source port indicates that a Telnet session has been initiated.
-- The data is flowing from server to client.
-- The destination port indicates that an HTTP session has been initiated.
-- ****The data listed is associated with the transport layer.
-- ****The source port does not support communication with the destination port that is listed.
75. Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C. during this attempt, a frame was captured with the source
MAC address 0050.7320.D632 and the destination MAC address 0030.8517.44C4. The packet inside the captured frame has an IP source
address 192.168.7.5, and the destination IP address is 192.168.219.24. At which point in the network was this packet captured?
-- Leaving host A
-- Leaving ATL
-- ****Leaving Dallas
-- Leaving NYC
76. Refer to the exhibit. Cable 1 and cable 2 have the ends wired for specific physical layer requirements. The table lists each segment
number and the cable which has been installed by the network technician between the network components on that segment. Referring to the
data given, which segments have the correct cable installed? (Choose three.)
-- ****Segment1
-- Segment2
-- ****Segment3
-- ****Segment4
-- Segment5
77. Refer to the exhibit. What three statements are true about the IP configuration that is shown? (Choose three.)
-- ****The address that is assigned to the computer represents private addressing.
-- ****The computer is unable to communicate outside of the local network.
