A service provider is implementing SR-TE to optimize traffic flow in its core network. The provider has two paths between two PEs: a low-latency path that is longer and a shorter path that has higher latency. The provider wants to steer delay-sensitive traffic over the low-latency path while keeping other traffic on the shortest path. Which SR-TE approach should be used?

Configure an SR-TE policy with an explicit segment list for the low-latency path and steer delay-sensitive traffic using a color community

Use RSVP-TE with a single explicit path for all traffic

Use LDP to prefer the low-latency path

Change the IGP metric of the low-latency path to be lower

A service provider is migrating legacy TDM circuits to an IP/MPLS backbone. The legacy network uses SONET/SDH for transport. The provider wants to preserve the existing TDM services while transitioning to a packet-based core. Which approach should be used?

Replace all TDM with IP-only services

Use Circuit Emulation over Packet (CEP) to carry TDM over MPLS

Keep SONET/SDH in the core and add MPLS overlay

A service provider is designing a long-haul transport network to interconnect two major cities. The distance is over 1,000 km. The provider wants to maximize fiber capacity by transmitting multiple wavelengths over a single fiber pair. Which technology should be used?

DWDM with optical amplifiers and dispersion compensation

A service provider is expanding its MPLS backbone into new access and aggregation domains. The provider wants to avoid running a full IGP across all domains and prefers to use a single label stack end-to-end. Which architecture and label distribution method should the provider implement?

Unified MPLS with LDP across all domains, using a single IGP instance

Unified MPLS with Segment Routing, using a single SRGB and IGP instances per domain

MPLS with RSVP-TE and per-domain label stacks

Traditional MPLS with LDP and a single IGP across all domains

A service provider is upgrading its long-haul optical network. The provider currently uses SONET/SDH with TDM. The provider wants to increase capacity and support flexible service delivery, but also wants to reduce the number of optical transponders and simplify the network. Which approach should the provider take?

Deploy a routed optical network with DWDM and coherent optics, eliminating the SONET/SDH layer

Continue using SONET/SDH with DWDM for transport

Use more wavelengths per fiber with the same SONET/SDH equipment

Replace SONET/SDH with a packet transport network using MPLS-TP
