When writing the executive summary, What is a limitation of or challenges with software-defined networks that must be listed?

Which network management framework can be used to develop a network architecture that contains business requirements analysis, gap analysis, and network diagrams as artifacts to be used for design and implementation later?

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.

Refer to the exhibit. All links are P2P Layer 3. A high availability application is synchronizing data between Host A and Host B. To increase the 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?

Two routers R1 and R2 are directly connected through an Ethernet link. Both routers are running OSPF over the Ethernet link and OSPF has been registered with BFD. R1 has been set up to transmit BFD at a 50 ms interval, but R2 can receive only at a 100 ms rate due to platform limitations. What does this mean?
