A municipal multitenant data center can stretch Layer 2 to a remote site for one agency but must not offer that stretch to others. What isolation principle applies?
Select an answer to reveal the explanation.
Short Explanation
Think of stretch like a VIP skybridge: you build it for the agency that paid for it, not for every office in the building. Multitenancy is not only separate VRFs—it is also which overlay services (including L2 DCI stretch) each tenant is allowed to use.
Full Explanation
Isolation is service-scoped as well as table-scoped. Offering L2 stretch or DCI features to one tenant does not obligate the fabric to enable the same capability for every other tenant. Per-VNI/per-instance policy decides who receives stretch. Blanket inheritance of DCI options or assuming stretch is merely an underlay OSPF setting misunderstands overlay multitenancy on JN0-683.
