Explanation

When creating a fabric in HPE Aruba Networking Fabric Composer, the Underlay network (B) and Overlay network (D) are the two required components because they define the complete two-layer architecture of the fabric - the underlay handles physical IP routing and reachability between devices, while the overlay (typically VXLAN-based) provides the logical tenant/segment abstraction on top of it. Together they form the foundational data plane of the fabric; neither alone is sufficient.

Why the distractors are wrong:

• A (Device roles): Roles are assigned to individual switches within the fabric but are not a discrete component configured when creating the fabric itself.
• C (API Gateway): This is not a Fabric Composer fabric component - it belongs to other infrastructure layers and has no direct role in fabric creation.

Memory tip: Think "U + O = Fabric" - Underlay is the physical foundation (routing/IP), Overlay is the logical ceiling (tunnels/VLANs). You always need the floor and the ceiling to build a room. If you see "fabric creation" on the exam, default to these two layers.
