Alcatel-Lucent NRS II – IP/MPLS Services — Question 42

Which of the following statements about behavior aggregate classification is TRUE?

Answer options

• A. It sets both the forwarding class and the packet’s dot1p, lsp-exp, precedence, or dscp field to the same value.
• B. It groups all packets together into a single aggregate stream, and gives all packets the same treatment.
• C. It copies the three most significant bits in the packet’s dscp field into the forwarding class.
• D. It assigns a forwarding class based on the packet’s dot1p, lsp-exp, precedence, or dscp value.

Correct answer: B

Explanation

Option B is correct because behavior aggregate classification indeed groups all packets into a single stream and treats them uniformly. Option A is incorrect as it does not specify the same value for all fields. Option C is also incorrect because it only refers to part of the classification process. Option D is misleading; while it does mention forwarding class determination, it does not accurately describe the aggregate nature of the classification.
