Alcatel-Lucent NRS II – Wide Area Network Services — Question 5

Which of the following are the default settings for the Alcatel-Lucent 7750 SR when using LDP?

Answer options

• A. Ordered control mode; downstream on demand.
• B. Ordered control mode; downstream unsolicited.
• C. Independent control mode; downstream on demand.
• D. Independent control mode; downstream unsolicited.

Correct answer: B

Explanation

The correct answer is B because the default setting for LDP on the Alcatel-Lucent 7750 SR is indeed ordered control mode with downstream unsolicited. Options A, C, and D are incorrect as they either describe different control modes or the type of downstream signaling that is not the default.
