Which protocol is needed to exchange threat details in rapid threat containment on Cisco FMC?

SGT (Security Group Tag) is a classification tag used to group network devices and users for policy enforcement, not a protocol for exchanging threat details.

SNMP v3 (Simple Network Management Protocol version 3) is used for monitoring and managing network devices, not for real-time threat intelligence exchange for rapid containment.

BFD (Bidirectional Forwarding Detection) is a protocol used for quickly detecting failures in a forwarding path between two routing devices, unrelated to threat details exchange.

Cisco pxGrid (Platform Exchange Grid) is a pervasive, bidirectional, and open security infrastructure framework that allows different security products to share context-rich information and telemetry. It is specifically designed to exchange threat intelligence and enable rapid threat containment actions, such as quarantining an infected endpoint, by integrating with systems like Cisco Identity Services Engine (ISE).
