Alcatel-Lucent NRS II – IP/MPLS Services — Question 6

Which of the following statements are TRUE regarding the building of a QoS-enabled network? (Choose two)

Answer options

• A. It is important that all packets are classified in the same way at all SAP-ingress points.
• B. Once a packet is classified to a forwarding class, it cannot change across the network.
• C. Packet enters a node will be treated as per the local hop's configured policy.
• D. Native IP packets entering a network port will be marked at the first network egress by default
• E. Native IP packets entering a network port will not be marked at the first network egress by default.
• F. Native IP packets entering a network port will be marked at the first network egress, regardless of the re-marking configuration.

Correct answer: C, E

Explanation

Option C is correct because packets are indeed processed based on the local hop's configured policy. Option E is also correct as it states that native IP packets will not be marked at the first network egress by default. Options A, B, D, and F are incorrect because they misrepresent the behavior of packet classification and marking within a QoS-enabled network.
