• Question 361:

  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.
  B. Flex Links operate only over single pairs of links.
  D. Flex Links automatically disable STP so no BPDUs are propagated.

  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. https:// www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SX/configuration/guide/book/flexlink.html
