CCDE: Cisco Certified Design Expert (Practical) — Question 68

The administrator of a small branch office wants to implement the Layer 2 network without running STP. The office has some redundant paths. Which mechanism can the administrator use to allow redundancy without creating Layer 2 loops?

Answer options

• A. Use two port channels as Flex links
• B. Use double-sided VPC on both switches
• C. Use fabric path with ECMP
• D. Use 802.3ad link bundling

Correct answer: A

Explanation

The correct answer is A because Flex links allow for redundancy without generating loops by automatically blocking one of the links until the active link fails. Options B and C involve complex configurations that are not suitable for the scenario, while D, while useful for link aggregation, does not specifically address the loop prevention needed in this context.
