350-601 Exam Results

The correct answers are C and D because of the standard Cisco ACI fabric bring-up workflow. When deploying a Cisco ACI fabric for the first time, the process begins with initial configuration of the first APIC controller. This includes assigning the fabric name, out-of-band management settings, and cluster parameters. Cisco documentation clearly defines this as the first mandatory step in fabric initialization, making option D correct.

After the APIC is configured and connected to the network, the fabric switches (leaf and spine) are automatically discovered using LLDP. Cisco ACI uses LLDP to detect connected devices and identify them as part of the fabric infrastructure. These discovered devices must then be manually registered (claimed) in the APIC GUI, which validates their role and integrates them into the fabric. This makes option C correct.

Option A is incorrect because APICs are not “registered” in that way; they are configured and clustered. Option B is incorrect because leaf switches do not require manual CLI configuration for APIC connectivity—they operate in ACI mode and are discovered automatically. Option E is incorrect because switches are not registered all at once blindly; they are registered after LLDP discovery.
