A city compares two leaf-spine pods in one campus with two geographically separate data centers. Which statement correctly distinguishes true DCI?
Select an answer to reveal the explanation.
Short Explanation
Two pods in one campus chatting over leaf-spine links are still one fabric neighborhood. True DCI is the link between data centers or sites, not every Clos hop inside a single hall.
Full Explanation
True DCI interconnects data centers or geographically or site-separated fabrics. Ordinary leaf-spine links inside one municipal fabric—even between two pods on one campus sharing one underlay—are fabric links, not DCI interconnect network types. Any leaf-to-spine link inside one fabric does not count as DCI. DCI is not merely the ZTP management VLAN between pods on the same TOR pair. Two pods on one campus do not always require EVPN stitching when they already share one underlay and are one fabric. Exam caveat: campus buildings can still be DCI if they are operated as separate fabrics with an interconnect—classification follows fabric/site boundary, not the word pod alone. Operational check: draw the ASN/fabric boundary for the city; label links that stay inside one underlay as fabric; label links that join separate DC fabrics as DCI; align overlay stretch configuration only on the true DCI borders. Keep a one-page fabric-versus-DCI boundary diagram in the NOC wiki to stop operators from calling intra-pod links DCI.
