Why each option

This question tests understanding of Cisco pxGrid's architecture and its primary use case for sharing contextual identity information.

AFrom a Cisco ASA to the Cisco OpenDNS service

pxGrid is not an integration between Cisco ASA and the OpenDNS/Umbrella service - that integration uses different APIs and is not pxGrid's defined role.

BFrom a Cisco ASA to the Cisco WSA

Communication between a Cisco ASA and a Cisco WSA (Web Security Appliance) uses separate integration mechanisms, not pxGrid.

CFrom a Cisco ASA to the Cisco FMC

ASA-to-FMC communication uses the Firepower Management Center's own management protocol, not pxGrid, which is an ISE-centric framework.

DFrom a Cisco ISE session directory to other policy network systems, such as Cisco IOS devicesCorrect

Cisco pxGrid (Platform Exchange Grid) is specifically designed to publish session and identity context from Cisco ISE (Identity Services Engine) to subscribing policy enforcement network systems such as Cisco IOS devices, firewalls, and third-party products. ISE acts as the hub in the hub-and-spoke architecture, sharing user, device, and posture data so that other systems can enforce consistent, context-based policy.
