200-901 Infrastructure and Automation Practice Question
Which TWO methods are commonly used to discover network devices in an automation environment? (Select exactly 2.)
⚠ Common exam trap

Correct answer & explanation
✓
Using LLDP or CDP to retrieve directly connected neighbor information
LLDP (IEEE 802.1AB) and CDP (Cisco Discovery Protocol) are Layer 2 protocols that allow network devices to advertise their identity, capabilities, and directly connected neighbors. In automation environments, these protocols enable dynamic discovery of the network topology without manual intervention, making them essential for automated inventory and mapping.
