a.The backup location should be secure and protected from physical and virtual threats. This may include on-premises backup storage, off-site backup storage, or cloud backup storageb.Configure a domain controller: You could configure a domain controller using a NOS like Windows Server.c.Customer input includes all pertinent network and site documentation.d.Finally, make sure to apply all available updates and patches to keep your Linux system secure.e.Customer input Review existing documentation about the network, and use verbal inputfrom the customer to obtain a first impression about the networkf.Traffic analysis If possible, use traffic analysis to provide information about the applicationsand protocols used and to reveal any shortcomings in the network.g.Network audit Perform a network audit, also called an assessment, which reveals details of the network and augments the customer’s description

4.1-4. What type of control plane?  We've seen that there are two approaches towards implementing the network control plane - a per-router control-plane approach and a software-defined networking (SDN) control-plane approach.  Which of the following actions occur in a per-router control-plane approach? The other actions that you don't select below then correspond to actions in an SDN control plane.  Group of answer choicesAll routers in the network send information about their incoming and outgoing links to a logically centralized controller.A router exchanges messages with another router, indicating the cost for it (the sending router) to reach a destination host.A control agent in router receives a complete forwarding table, which it installs anduses to locally control datagram forwarding.Routers send information about their incoming and outgoing links to other routers in the network.
