Alcatel-Lucent NRS II – IP/MPLS Services — Question 2

Which of the following are possible criteria for classifying packets at the network port ingress on the Alcatel-Lucent 7750 SR? (Choose three)

Answer options

• A. The EXP bits in the MPLS header.
• B. The packet's source and destination IP addresses.
• C. The packet's DSCP bits.
• D. The dot1p bits in the frame header.
• E. The ID of an SDP that is transporting the packet.

Correct answer: A, C, D

Explanation

Options A, C, and D are valid criteria for classifying packets at network port ingress on the Alcatel-Lucent 7750 SR, as they directly pertain to the packet's header information used in traffic management. Option B is incorrect because while IP addresses can be relevant for routing decisions, they are not typically used for ingress classification in this context. Option E is also not used for classification at ingress, as it relates more to the transport mechanism rather than packet classification criteria.
