Solution
Happy New Year 2017.
(1) EPON is based on Ethernet standards.
And hence it uses Non - virtual tunelling.
Answer is (b).
(2) Logs are maintained by organizations for all of the options provided.
Answer is (d)
(3) Splitter combines Voice signal and Broadband signal.
Because the data and video signal from broadband network are converted
to an analog signal by ATU-C and multiplexed and demultiplexed.
This analog signal contains voice and broadband signal.
Answer is (b)
(4) Integrity involves maintaining the consistency, accuracy, and trustworthiness of data over its entire life cycle.
Data must not be changed in transit, and steps must be taken to ensure that data cannot be altered by unauthorized people.
Answer is (b)
