Which of the following are the main requirements of data center interconnection scenarios? (Multiple Choice)

Question

Options

• ASingle-fiber bandwidth capability
• BWhether the device form meets the requirements for data center deployment
• CSafe and reliable
• DMulti-service carrying capability

• A
  80% (44)
• D
  20% (11)

Explanation

Data center interconnection (DCI) has three core requirements that reflect the unique constraints of connecting geographically separated data centers. Single-fiber bandwidth capability (A) is essential because DCI solutions rely on dense wavelength division multiplexing (DWDM) to maximize throughput over existing fiber infrastructure - high per-fiber capacity directly determines how efficiently DCs can be linked. Device form factor (B) matters because data centers impose strict physical constraints: equipment must fit standard rack dimensions and meet power/cooling requirements specific to DC environments. Safety and reliability (C) is non-negotiable since DCI carries mission-critical traffic; any failure can disrupt entire services, so redundancy and protection switching are fundamental demands.

Option D (Multi-service carrying capability) is incorrect as a primary DCI requirement - that capability is characteristic of metro and carrier aggregation networks, which must support diverse service types (voice, video, data). DCI scenarios are specifically optimized for large-volume, homogeneous Ethernet/IP traffic between data centers, not multi-service flexibility.

Memory tip: Think of DCI requirements using the acronym "FBI" - Fiber bandwidth, Building/form factor, and Integrity (safe & reliable). Multi-service is a carrier network concern, not a DC-to-DC concern.
