Which of the following statements regarding scheduling are TRUE? (Choose two)

Question

Options

• AScheduler policies cannot be children of an egress port-scheduler.
• BHQoS provides a static method of allocating scheduling resources to each queue and/or child.
• CScheduler policies can be applied to the MDA to schedule network ingress traffic.
• DEvery time a scheduler-policy is assigned to a SAP, a new hardware scheduler is created to
• EA scheduler applied to multiple SAPs within the same service will result in a single hardware

• A
  3% (1)
• B
  3% (1)
• C
  94% (32)

Explanation

C and D are correct because on Nokia SR OS platforms, scheduler policies can indeed be applied to an MDA (Media Dependent Adapter) to govern network ingress traffic (C), and each time a scheduler-policy is assigned to a SAP, the system instantiates a new, dedicated hardware scheduler for that SAP rather than reusing one (D). This per-SAP instantiation is a key architectural behavior that distinguishes SAP assignment from other contexts.

Why the distractors are wrong:

• A is false - scheduler policies can be children of an egress port-scheduler; this is a fundamental part of HQoS hierarchy design.
• B is false - HQoS is a dynamic bandwidth allocation mechanism, not static; it adjusts resources based on demand, weights, and configured rates across the hierarchy.
• E is the opposite of D - applying a scheduler to multiple SAPs results in multiple hardware schedulers (one per SAP), not a single shared instance.

Memory tip: Think "Create Dedicated" - scheduler policies Cover MDA ingress, and each SAP assignment Dedicates a new hardware scheduler. If you remember that SAPs are always isolated in hardware, you can eliminate both A (hierarchy is real) and E (no sharing across SAPs) quickly.
