CCIE Data Center (legacy) — Question 80

Which three statements about ACI border leaf are true? (Choose three.)

Answer options

• A. Only 32 border leaves are supported in an ACI fabric.
• B. There can only be 2 border leaves in an ACI fabric. The first two leaves that are discovered in an ACI fabric are always selected as border leaves.
• C. The border leaves are ACI leaves that provide Layer 3 connections to outside networks.
• D. The border leaves are dedicated leaf switches that support only Layer 2 and Layer 3 out in an ACI fabric.
• E. The border leaf can also be used to connect to compute, IP storage, and service appliances.

Correct answer: B, C, E

Explanation

Answer B is correct because an ACI fabric is limited to two border leaves, which are chosen based on discovery order. C is accurate as border leaves do provide Layer 3 connections to outside networks, and E is also true since border leaves can connect to various devices. Options A and D are incorrect; A is false as the number of border leaves is limited to two, and D is misleading since border leaves support both Layer 2 and Layer 3, not just one.
