The correct answer is D. In-band IP. Option D is correct because acidiag fnvread on the APIC displays the in-band IP addresses (/32 TEP - Tunnel Endpoint addresses) assigned to each ACI fabric node, which are used for VXLAN overlay communication through the fabric itself.

Explanation

Option D is correct because acidiag fnvread on the APIC displays the in-band IP addresses (/32 TEP - Tunnel Endpoint addresses) assigned to each ACI fabric node, which are used for VXLAN overlay communication through the fabric itself. Option B (Out-of-band) is wrong because OOB IPs are on an isolated management network reached via dedicated physical management ports (mgmt0), completely separate from the fabric. Option C (Management IP) is a vague distractor - "management IP" doesn't specify whether it's in-band or OOB, and the TEP addresses shown here aren't dedicated management IPs. Option A (Infrastructure IP) is the most tempting distractor because TEP addresses do come from the ACI infrastructure address pool, but the exam distinguishes between the pool concept (infrastructure) and the access method (in-band vs. OOB) - these addresses traverse the fabric, making them in-band by classification.

Memory tip: Think "In-band = In the fabric." The /32 addresses shown by acidiag fnvread flow through the ACI fabric, while OOB addresses bypass it entirely via a separate wire.
