VOIP is being implemented on the Company network. In a properly designed network, what
is the maximum amount of time a voice package should spend crossing a network?

A.
90 milliseconds

B.
120 milliseconds

C.
150 milliseconds

D.
240 milliseconds

Explanation:
Delay is the time it takes for VoIP packets to travel between two endpoints and you should
design networks to minimize this delay. However, because of the speed of network links and
the processing power of intermediate devices, some delay is expected. The human ear
normally accepts up to about 150 milliseconds (ms) of delay without noticing problems (the
ITU standard recommends no more than 150 ms of one-way delay).
