Alcatel-Lucent NRS II – Wide Area Network Services — Question 10

Which of the following statements regarding DiffServ-TE LSPs is true?

Answer options

• A. The Maximum Allocation Model (MAM) provides the most efficient bandwidth utilization model
• B. In the Maximum Allocation Model (MAM), each CT receives dedicated bandwidth constraints.
• C. In the Russian Doll Model (RDM), a CT2 LSP automatically preempts a CT1 LSP.
• D. Using the Russian Doll Mode! (RDM), a CT1 LSP may use unreserved CTO bandwidth.

Correct answer: B

Explanation

The correct answer is B because the Maximum Allocation Model (MAM) indeed assigns dedicated bandwidth constraints to each CT, ensuring that resources are allocated effectively. Option A is incorrect as MAM does not necessarily provide the most efficient utilization compared to other models. Options C and D are also incorrect; the Russian Doll Model (RDM) does not automatically preempt with CT2 over CT1, and CT1 LSPs cannot use unreserved CTO bandwidth under RDM.
