In a redundant hub and spoke "wheel" design, all spokes are connected to the hub, and spokes are connected to other spokes as well. During failure on one spoke link, the traffic from that site can be sent to a neighboring site for it to be forwarded to the hub site. But during peak hours, a link is overloaded and traffic is re-routed to a neighbor, which subsequently becomes overloaded. This overload results in network traffic oscillation as the load varies at each spoke site. This design provides more redundancy but not more resiliency because the routing protocol must process many alternate paths to determine the lowest cost path. Which two design
changes help to improve resilience in this case? (Choose two.)
A legacy enterprise is using a Service Provider MPLS network to connect its head office and branches. Recently, they added a new branch to their network. Due to physical security concerns, they want to extend their existing IP CCTV network of the head office to the new branch, without any routing changes in the network. They are also under some time constraints. What is the best approach to extend the existing IP CCTV network to the new branch, without incurring any IP address changes?
Which three Cisco products are used in conjunction with Red Hat to provide an NFVi solution? (Choose three.)

Which technique can the company use in their design to ensure that the traffic is not process switched?
It is often seen that companies pick a cloud vendor solely based on technical preferences without putting enough weight on the business strategies that are driving the cloud initiatives Which strategic requirement may come into play where it is more likely that the decision makers will look to leverage laaS over SaaS or PaaS?
