Why each option

The question asks for two functions performed by an edge node within a network fabric, such as Cisco SD-Access.

Aauthenticates endpointsCorrect

Edge nodes, typically access switches, are responsible for authenticating endpoints (users and devices) as they connect to the network fabric, enforcing security policies at the point of access.

Bprovides the default entry point for fabric traffic

Edge nodes provide *multiple* entry points for traffic, not a singular 'default entry point', which is usually handled by a border node for external connectivity.

Cprovides multiple entry and exit points for fabric trafficCorrect

Edge nodes serve as the distributed points where endpoints physically connect to the fabric, thus providing multiple entry and exit points for user and device traffic into and out of the overlay network.

Dprovides the default exit point for fabric traffic

Edge nodes primarily handle local endpoint connectivity; a 'default exit point' for the fabric is typically managed by a border node responsible for external connectivity.

Eprovides a host database that maps endpoint IDs to a current location

The host database, which maps endpoint IDs to locations, is maintained by the centralized controller (e.g., Cisco DNA Center) in a fabric, not directly by individual edge nodes.
