What is the main purpose of DiffServ-aware Traffic Engineering (DS-TE)?

To replace MPLS TE with a simpler QoS mechanism.

To classify packets at the edge and apply PHBs in the core.

To provide per-class bandwidth guarantees by integrating DiffServ QoS classes with MPLS TE.

To provide end-to-end QoS guarantees using RSVP reservations.

Which feature is characteristic of DiffServ-aware Traffic Engineering (DS-TE)?

It is only applicable to voice traffic.

It uses a single bandwidth pool for all traffic classes.

It does not use MPLS TE tunnels.

It allows different classes of traffic to have different bandwidth reservations.

A service provider is deploying MPLS TE and needs to provide per-class bandwidth guarantees for voice, video, and data across the network. The provider wants to integrate DiffServ classes with TE to ensure that each class has its own bandwidth reservation. Which technology should be used?

Class-Based Tunnel Selection (CBTS)

DiffServ-aware Traffic Engineering (DS-TE)

Policy-Based Tunnel Selection (PBTS)

Which statement is true about the Russian Doll Model (RDM) for MPLS TE bandwidth constraints?

Lower-priority classes can use bandwidth from higher-priority classes.

Each class has a completely independent bandwidth pool.

The total bandwidth is divided equally among all classes.

The bandwidth constraints are nested, allowing higher-priority classes to use bandwidth from lower-priority classes.

A customer requires end-to-end QoS guarantees for a critical application, with bandwidth reserved along the entire path from source to destination. The provider is considering using RSVP to reserve resources for each flow. Which QoS model does this describe?
