According to the VCF 9.0 Container Registry Documentation , Harbor is defined as:
" Harbor is an open source registry that secures artifacts with policies and role-based access control, ensures images are scanned and free from vulnerabilities, and signs images as trusted. " This description aligns exactly with option A. Harbor is not Bitnami (B), though it integrates with open- source images. It includes vulnerability scanning but is not only an image scanner (C). It does not require GitHub as a source (D); Harbor can integrate with multiple registries.
Therefore, Harbor's primary role within VCF is to act as a secure image registry with RBAC, scanning, and signing capabilities .
