Which two technologies are examples of Cisco IP+Optical innovation? (Choose two.)

Question

Options

• Ahybrid Raman amplification
• Bproactive protection
• Csegment routing
• DIP-over-DWDM
• Edispersion compensation

• A
  15% (6)
• B
  77% (30)
• C
  5% (2)
• E
  3% (1)

Explanation

Proactive Protection (B) is a Cisco IP+Optical innovation that detects impending optical layer failures and reroutes traffic before an outage occurs, rather than reacting after the fact - a distinctly Cisco-developed capability. IP-over-DWDM (D) is the cornerstone of Cisco's IP+Optical strategy, collapsing the traditional multi-layer stack by connecting IP routers directly to DWDM optical transport, cutting cost and complexity.

The distractors are general optical/networking technologies, not Cisco IP+Optical innovations: hybrid Raman amplification (A) is a signal amplification technique common across vendors; segment routing (C) is a Cisco Layer 3 traffic engineering innovation, but belongs to the IP/MPLS domain, not the IP+Optical integration story; and dispersion compensation (E) is a standard fiber optic technique for managing signal degradation over distance.

Memory tip: Think "PP+D" - Proactive Protection and Direct IP-over-DWDM are the two things Cisco specifically brands as IP+Optical innovations. If an answer choice sounds like a generic optical physics concept (amplification, dispersion) or a pure routing protocol, it's not the Cisco IP+Optical answer.
