A. B. C. D. E.AC.
When a new ACI fabric is created, it must be discovered by the APICs. To ensure successful discovery of the APICs into the fabric, the following two actions must occur:
The fabric controller target size must be equal to or greater than the number of APICs. The fabric controller target size refers to the maximum number of APICs that can be registered with the fabric. This value is set during the initial configuration of the fabric. If the number of APICs to be registered is greater than the fabric controller target size, the registration process will fail. Therefore, it is important to ensure that the fabric controller target size is set equal to or greater than the number of APICs.
LLDP must be enabled on the virtual interface card of the APIC. Link Layer Discovery Protocol (LLDP) is used by the APICs to discover the fabric and establish connectivity. LLDP must be enabled on the virtual interface card (vNIC) of the APIC so that it can discover and communicate with the fabric switches. LLDP allows the APIC to obtain information about the switches, such as their names, chassis IDs, and port IDs. This information is used by the APIC to establish connectivity and configure the fabric.
Therefore, options A and C are the correct answers. Option B is incorrect as setting a BIOS password is not a requirement for APIC discovery. Option D is also incorrect as the controller must be manually registered with the fabric during the initial configuration. Finally, option E is incorrect as LLDP must be enabled on the vNIC of the APIC.
