Explanation

On the Alcatel-Lucent 7750 SR, network-queue policies are designed to manage queuing on the physical forwarding plane - specifically at ingress MDAs and egress Ethernet network ports. Router interfaces (A) are logical constructs layered above the physical hardware, so QoS at that level uses different policy types (e.g., scheduler policies); network-queue policies don't bind there. Ingress Ethernet network ports (C) are also invalid targets - on ingress, the network-queue policy attaches at the MDA level (answer B), not the individual port, so applying it per-port is not supported. Service SAPs (E) belong to the service layer and use their own dedicated QoS framework (sap-ingress/sap-egress policies), making them incompatible with network-queue policies entirely.

The distractors B (Ingress MDA) and D (Egress Ethernet network ports) are the two correct attachment points for network-queue policies and are therefore valid - not excluded.

Memory tip: Think "MDA in, Port out" - network-queue policies go inward on MDAs and outward on ports. Anything logical (router interfaces), granular-ingress (individual ports), or service-layer (SAPs) is off-limits.
