Designing Cisco Data Center Infrastructure (DCID, legacy) — Question 87

What allows for STP to be disabled yet support a loop-free topology even on link or switch failure?

Answer options

• A. LACP
• B. OTV
• C. vPC
• D. vPC+
• E. FabricPath

Correct answer: E

Explanation

FabricPath allows for a loop-free network design without the need for Spanning Tree Protocol (STP) by utilizing a switched fabric architecture, which helps in managing redundancy and failures effectively. The other options, while related to network redundancy and link aggregation, do not provide the same level of loop prevention and topology management without relying on STP.
