Explanation

Only one SAP-ingress QoS policy can be applied to a SAP at a time in Nokia SR OS. This is a deliberate architectural constraint - all ingress traffic classification, metering, and queuing for a given SAP must be consolidated into a single policy, ensuring deterministic and conflict-free traffic handling at the service access point.

Options B through F (2, 3, 4, 5, and 8) are all incorrect because Nokia SR OS does not support stacking or layering multiple SAP-ingress policies on a single SAP. If you need to handle multiple traffic types or classes, you define multiple FC (Forwarding Class) mappings and meters within that one policy - not by applying additional policies on top.

Memory tip: Think "one door, one doorman" - a SAP is the single entry door into the service, and only one ingress policy can stand guard at that door. If the exam tries to tempt you with powers-of-two (2, 4, 8) or a sequence (1, 2, 3...), remember that Nokia's QoS model enforces a strict 1:1 binding between a SAP and its ingress policy.
