Company XYZ wants to prevent switch loops caused by unidirectional point-to-point link conditions on Rapid PVST+ and MST. Which technology can be used in the design to meet this requirement?
An enterprise solution team is performing an analysis of multilayer architecture and multicontroller SDN solutions for multisite deployments. The analysis focuses on the ability to run tasks on any controller via a standardized interface. Which requirement addresses this ability on a multicontroller platform?
Which two conditions must be met for EIGRP to maintain an alternate loop-free path to a remote network?
(Choose two.)

Refer to the exhibit. A service provider has a requirement to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2. Which two ways to design this solution are true?
(Choose two)
synchronizing data between host A and host B. To increase chance of delivery the same data is sent twice from host A on two different NICs toward the two NICs on host B.
Which solution must be deployed in the network to ensure that any failure in the network does not trigger data loss on host B?
