Huawei Certified Network Professional – Routing and Switching v2 (HCNP-RS) — Question 36

The IP packet has a special field to mark the QoS. For example, the last 6 bits in the ToS field of an IPv4 packet mark the DSCP value.

Answer options

• A. True
• B. False

Correct answer: B

Explanation

The statement is incorrect because the last six bits in the ToS field of an IPv4 packet are used for Differentiated Services Code Point (DSCP), which is part of the overall 8 bits available for DSCP marking. Therefore, the correct answer is B, as the description is misleading.
