A service provider is deploying an Open RAN (ORAN) network. The provider wants to support multiple vendors for O-RU, O-DU, and O-CU. The provider is concerned about latency and synchronization in the fronthaul. Which design consideration is most critical?

Use a single vendor for all RAN components to avoid interoperability issues.

Use best-effort Ethernet for fronthaul.

Use a centralized O-DU to reduce latency.

Implement a fronthaul transport network with low-latency and precise time synchronization (e.g., IEEE 1588 PTP)

A mobile operator is deploying a 5G standalone core with network slicing. The operator wants to provide a low-latency slice for autonomous driving and a broadband slice for video streaming. The transport network must support different QoS and routing for each slice. Which approach should be used to ensure end-to-end slice isolation?

Use separate AMFs for each slice.

Use separate network slices with dedicated UPFs and transport network slicing (e.g., FlexE or SRv6 network slicing)

Use the same transport network with best-effort delivery.

Use a single UPF for all slices and rely on DiffServ marking.

A cable operator is planning to upgrade its HFC network to offer gigabit-class broadband services. The operator wants to increase downstream capacity and improve spectral efficiency. Which technology should be deployed?

DOCSIS 3.1 with OFDM modulation

A service provider wants to implement traffic engineering to steer traffic along a specific path that avoids a congested link. The network is running Segment Routing with OSPF. The provider wants to avoid using RSVP-TE. Which mechanism should be used to define the explicit path?

A BGP VPNv4 route with a specific next hop

A segment list containing adjacency SIDs and/or prefix SIDs

An RSVP-TE tunnel with explicit route objects

A static MPLS label stack manually configured on each router

A service provider is upgrading its access network to deliver higher broadband speeds to residential customers. The current network uses ADSL2+ over twisted-pair copper. The provider wants to offer speeds up to 100 Mbps downstream while reusing the existing copper infrastructure. Which technology should be deployed?
