Explanation

recommended minimum sizing has the following requirements: Three or more Cisco APIC controllers that are dual connected to different leaf Switches for maximum resilience. Note that the fabric is manageable even with just one controller and operational without a controller. I’m not sure what ‘manageable’ means, is it still an ACI fabric or does it revert to a different state. It seems weird to me you would no longer have your ACI fabric if one/ two of your three APIC’s went offline. Not usually how redundancy works. This Cisco topic seems to indicate it will still **https : // **supportforumsciscocom /discussion/12448836/apic-cluster-why-minimum-3- Interesting your reasoning. “Manageable”, means that you can still make changes, add/remove things, etc. So, now reading your comments, it makes sense that if the is talking about continuing to operate, the answer must be 1. I’ve seen 3 as the answer in all dumps but now I doubt it. –> Nothing is correct. ARCH Design guide states correct answer is 0 (zero): “The recommended minimum sizing has the following requirements: Three or more Cisco APIC controllers that are dual-connected to different leaf switches for maximum resilience. Note that the fabric is manageable even with just one controller and operational without a controller.” = Management min 1
