Correct Answer: C
Question 7:
When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two )
A. Serialization delays are invariable because they depend only on the line rate of the interface
B. Serialization delays are variable because they depend on the line rate of the interface and on the type of packet being serialized.
C. Serialization delay is the time required to transmit the packet on the physical media.
