Create a guest wireless network
A network technician has been given a requirement to expand the copper
network in their company's leased premises, which has lately added
three new offices. In the currently leased area, the distance between the
offices and the network's closest node is roughly 101 m. When testing a
test connection run between the two areas, the technician sees a
significant level of attenuation.
Which device will enable the technician to boost the poor signal and
connect the entire rental office?
A. Repeater
B. Access point
C. Dumb hub
D. Splitter – Correct Answer - Repeater
Which assessment is the first part of the design process?
A. Hardware
B. Directory
C. Needs
D. Facilities – Correct Answer - Needs
Which electrical system is required for network equipment according to
industry standards?
pg. 3

A. Isolated
B. Integrated
C. Filtered
D. Buffered – Correct Answer - Isolated

content using analog signals.
Which multiplexing technique should be used?
A. Frequency-division multiplexing
B. Code-division multiplexing
C. Synchronous time-division multiplexing
D. Integrated Services Digital Network (ISDN) multiplexing – Correct
Answer - Frequency-division multiplexing
A network administrator is setting up a network that will utilize lasers to
send analog data through fiber-optic cable. Which multiplexing
technique should the administrator use?
