In an intent-based network, which statement best describes end-to-end verification?

• A. Verifies the network's path from end to end
• B. Verifies only edge devices
• C. Verifies nothing
• D. Verifies only at the core

Answer: (A)

End-to-end verification means checking that the intended policy and service are realized along the entire path from the source to the destination. In an intent-based network, this involves validating that connectivity, security, QoS, and other policy requirements are enforced across every segment of the route—edge, access, distribution, core, and any overlays—so the actual traffic matches what was intended. This broader view is essential because focusing only on one part of the network (like just the edge or just the core) can miss problems that occur as traffic traverses the full path. By verifying the complete end-to-end journey, the network can continuously ensure that the operator’s intent is achieved regardless of changes or failures along the way.
