A cable operator is upgrading its HFC network to provide gigabit-class broadband services. The operator currently uses DOCSIS 3.0. Which upgrade path should the operator take to achieve higher downstream throughput and better spectral efficiency?

Deploy VDSL2 vectoring in the access network

Increase the number of T1/E1 lines

Upgrade to DOCSIS 3.1, which uses OFDM and supports higher order modulation

A service provider is evaluating SRv6 for its new core network. The network is IPv6-only. The provider wants to simplify the network by eliminating MPLS in the core. Which statement correctly describes how SRv6 achieves this?

SRv6 encodes the path in an IPv6 extension header using a list of SRv6 SIDs

SRv6 uses RSVP-TE to establish paths

SRv6 uses MPLS labels encapsulated in IPv6 packets

SRv6 requires a separate label distribution protocol like LDP

A service provider is designing a unified MPLS network to span access, aggregation, and core domains. The provider wants to minimize the number of label operations at domain boundaries and avoid running a full IGP across all domains. Which design should the provider implement?

Use Segment Routing with a common SRGB across all domains and inter-domain SID advertisement via BGP-LS

Use BGP-labeled unicast (BGP-LU) without SR

Use RSVP-TE with per-domain LSPs and label stacking at boundaries

Use LDP with a single IGP instance across all domains

In an MPLS network, which router role is responsible for pushing a label onto an incoming IP packet?

Label switch router (LSR) at the egress

How does Segment Routing simplify MPLS label distribution compared to LDP?

It eliminates the need for a separate label distribution protocol by encoding SIDs in the IGP.

It uses BGP to distribute labels instead of LDP.

It uses static labels on every router.

It requires RSVP-TE to establish LSPs.
