CCDE: Cisco Certified Design Expert (Written) — Question 26

When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two.)

Answer options

• A. Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.
• B. Serialization delay depends not only on the line rate of the interface but also on the size of the packet.
• C. Serialization delays are invariable because they depend only on the line rate of the interface.
• D. Serialization delays are variable because they depend only on the size of the packet being serialized.
• E. Serialization delay is the time required to transmit the packet on the physical media.

Correct answer: B, E

Explanation

The correct answers, B and E, highlight that serialization delay is affected by both the line rate and the packet size, as well as defining serialization delay itself. Options A, C, and D are incorrect because they either misstate the variability of serialization delay or incorrectly attribute it solely to one factor.
