On the Alcatel-Lucent 7750 SR, which of the following QoS-related policies can be configured on a SAP? (Choose three)

Question

Options

• AThe slope-policy
• BThe SAP-ingress policy
• CThe SAP-egress policy
• DThe network-queue policy
• EThe scheduler-policy

• A
  11% (3)
• B
  70% (19)
• D
  19% (5)

Explanation

On the 7750 SR, a SAP (Service Access Point) is the customer-facing attachment point where traffic enters or exits a service, and it uses SAP-ingress (B) and SAP-egress (C) policies to classify and meter/shape traffic in each direction - these are the foundational per-SAP QoS tools. The scheduler-policy (E) can also be applied directly to a SAP to control how queues are scheduled when a multi-service site (MSS) isn't in play, making B, C, and E the three correct answers.

Why the distractors are wrong:

• A (slope-policy): Slope policies control WRED (Weighted Random Early Detection) drop probability curves and are applied inside a queue definition within a SAP-ingress/egress policy - not directly on the SAP itself.
• D (network-queue policy): This policy applies to network (core-facing) ports and interfaces, not to SAPs, which are customer-facing.

Memory tip: Think "SAP = Customer Edge" - anything a customer touches (ingress, egress, scheduling) goes on the SAP. Network-queue and slope policies live deeper in the hierarchy: one on the core side, one inside queue definitions. If the policy name includes "SAP," it attaches to a SAP; if it says "network," it doesn't.
