Which two data center network architectures might be proposed by other vendors to compete with Juniper Networks Virtual Chassis Fabric (VCF) solution? (Choose two.)

Question

Options

• ATRILL
• BFCoE
• CSON ET 1
• Dthree-tier architecture

• A
  81% (22)
• B
  7% (2)
• C
  11% (3)

Explanation

TRILL (Transparent Interconnection of Lots of Links) is a direct architectural competitor to VCF because it also solves spanning tree limitations by enabling multi-path Layer 2 forwarding across a flat fabric - vendors like Cisco implemented TRILL-based solutions (e.g., FabricPath) as their answer to Juniper's VCF. The traditional three-tier architecture (access → distribution → core) remains something competing vendors may propose as a proven, alternative design philosophy, especially for environments not yet ready to adopt fabric-based approaches. FCoE (Choice B) is a storage convergence protocol for running Fibre Channel traffic over Ethernet - it addresses SAN consolidation, not data center switching fabric design, so it doesn't compete with VCF. SONET (Choice C) is a WAN/carrier optical transport standard and has no relevance to data center LAN architecture whatsoever.

Memory tip: Think "Two Types of competition" - TRILL (modern flat-fabric rival) and Three-tier (traditional layered rival). Both challenge VCF but from opposite directions: one matches its sophistication, the other offers familiar simplicity.
