A company has two sites: Site A and Site B. The administrator would like to manage the VMware vCenter inventories in both sites from a single vSphere Client session. Which vCenter feature must be conf

VMware Certificate Authority (VMCA) manages certificates for vCenter components but does not directly link vCenter inventories for cross-site management.

VMware Site Recovery Manager (SRM) is a disaster recovery solution for orchestrating failover and failback, not for unified daily management of separate vCenter inventories.

While vCenter Single Sign-On (SSO) is a prerequisite for Enhanced Linked Mode and provides authentication, it alone does not link the inventories across different vCenter servers for single-pane management.

Enhanced Linked Mode (ELM) connects multiple vCenter Server instances by sharing their authentication domains (vCenter Single Sign-On) and inventory, allowing an administrator to view and manage all linked vCenter Server instances from a single vSphere Client session. This provides a unified management experience across multiple sites or vCenter instances.
