Exam 300-620 topic 1 question 16 discussion

Probably A is correct answer. D is wrong because APIC uses LLDP and not CDP during discovery process. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/1-x/aci-fundamentals/b_ACI-Fundamentals/b_ACI-Fundamentals_chapter_010011.html: "Each APIC in the Cisco ACI uses an internal private IP address to communicate with the ACI nodes and other APICs in the cluster. The APIC discovers the IP address of other APIC controllers in the cluster through the LLDP-based discovery process."

Letter A is correct!

A is correct. Address pool for TEP addresses: Enter the address pool for TEP addresses. The default IP address pool for TEP tunnel endpoint addresses is 10.0.0.0/16. This value is for the infrastructure VRF used for internal fabric communication. This subnet will not be exposed to your legacy network unless you are deploying the Cisco AVS/AVE. Regardless, the recommendation is to assign an unused subnet of size between and /16 and /21 subnet. The size of the subnet used will impact the scale of your pod. Most customers allocate an unused /16. This value cannot be changed once configured. Modifying this value requires a wipe of the fabric. Reference: Cisco U

B is wrong because the AV is an object mantained by the APICs, to keep mappings between APIC IPs and IDs, not of the switches. The switches receive and advertise further AV pairs from one APIC to other APICs. Thus the correct one is A.

Answer is B, https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/1-x/aci-fundamentals/b_ACI-Fundamentals/b_ACI-Fundamentals_chapter_010011.html#concept_A9C1C7BB9E8C4798AAD58CBA472B3BA5 >>When a switch reboots, the policy element (PE) on the leaf gets its AV from the APIC. The switch then advertises this AV to all of its neighbors and reports any discrepancies between its local AV and neighbors' AVs to all the APICs in its local AV.<<

A is correct

Agreed in A.

A is correct

A is correct

A is correct Explain: The following describes the APIC cluster discovery process: Each APIC in the Cisco ACI uses an internal private IP address to communicate with the ACI nodes and other APICs in the cluster. The APIC discovers the IP address of other APIC controllers in the cluster through the LLDP-based discovery process.

A is correct

I concur.
