Which two statements are correct regarding Flex Links? (Choose two.)
A . An interface can belong to multiple Flex Links.
B . Flex Links operate only over single pairs of links.
C . Flex Link pairs must be of the same interface type.
D . Flex Links automatically disable STP so no BPDUs are propagated.
E . Failover from active to standby on Flex Links takes less than a second.
Answer: BD
Explanation:
Flex Links are a pair of a Layer 2 interfaces (ports or port channels), where one interface is configured to act as a backup to the other. Flex Links are typically configured in service-provider or enterprise networks where customers do not want to run STP. Flex Links provide link-level redundancy that is an alternative to Spanning Tree Protocol (STP). STP is automatically disabled on Flex Links interfaces. A backup link does not have to be the same type as the active link.
