Designing Cisco Network Service Architectures (ARCH, legacy) — Question 94

While troubleshooting an Application Centric network cluster, an engineer sees that an APIC has gone offline.
What is the minimum number of APICs required for a production ACI fabric to continue to operate?

Answer options

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: C

Explanation

For a production ACI fabric to maintain operation, a minimum of three APICs is required to ensure redundancy and fault tolerance. If only one or two APICs are present, the fabric would not be able to achieve the necessary quorum and could lead to a complete failure of the management plane. Thus, options A, B, and D do not meet the operational requirements for a stable ACI environment.
