What is the driving force behind Cisco Unified Carrier Ethernet and mobile backhaul?

Question

Options

• Areduction in the number of access technologies that require integration into the core
• Bmove away from usage of traditional ATM and TDM technologies
• Csupport for any access over any media technologies
• Dobsolescence of 2G mobile technologies

• A
  6% (1)
• B
  6% (1)
• C
  75% (12)
• D
  13% (2)

Explanation

C is correct because Cisco Unified Carrier Ethernet and mobile backhaul are fundamentally designed around the principle of supporting any access technology over any media - whether that's 2G, 3G, 4G/LTE, Wi-Fi, or fiber - providing a unified, flexible transport layer rather than technology-specific silos.

Why the distractors are wrong:

• A is backwards - the driving force is actually about integrating more access technologies, not reducing them. Carrier Ethernet unifies diverse access types.
• B is a consequence or goal, not the driving force. While migration away from ATM/TDM happens as a result, it's not what motivates the architecture.
• D is too narrow and factually misleading - 2G obsolescence isn't a driver; in fact, supporting legacy 2G alongside newer technologies is part of why unified backhaul matters.

Memory tip: Think of the phrase "any-any" - any access, any media. Cisco's unified approach is essentially a universal adapter for carrier networks, and "universal" maps directly to option C.
