20+ practice questions focused on Automation and Quality of Services — one of the most tested topics on the Cisco SPCOR / CCNP Service Provider Core 350-501 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Automation and Quality of Services PracticeIn the DiffServ model, which DSCP value is used for Expedited Forwarding (EF) to support voice traffic?
Explanation: EF is defined by DSCP 46 (binary 101110) to provide low-loss, low-latency service for voice.
An SP engineer is configuring hierarchical QoS on a PE router to enforce a per-subscriber bandwidth contract of 10 Mbps and prioritize voice within that contract. Which MQC configuration sequence is correct?
Explanation: Hierarchical QoS uses a parent policy for shaping and a child policy for classification and priority queuing. The child is applied to the parent's class-default.
In an SP MPLS core, a PE router maps incoming DSCP values to MPLS EXP bits. Which statement about EXP marking is accurate when using the DiffServ Tunneling Model?
Explanation: In the DiffServ Tunneling Model, the Short Pipe model specifically instructs the egress PE to ignore the MPLS EXP bits for queuing and instead use the original IP DSCP value. This preserves the end-to-end QoS marking across the MPLS core, making option D correct. The Pipe model, by contrast, uses the EXP bits at the egress PE, which is why option B is incorrect.
An SP network uses NSO for service orchestration. Which component in NSO provides the abstraction layer to communicate with different device types using protocols like NETCONF or CLI?
Explanation: NEDs (Network Element Drivers) are plugins that translate NSO's service models to device-specific configurations.
When using NETCONF to edit a running configuration on a Cisco IOS XR router, which sequence of operations is correct?
Explanation: NETCONF uses <edit-config> to modify the config; <get-config> retrieves; <lock> prevents concurrent edits.
