What are two common approaches to analyzing and designing networks? (Choose two.)

When a company network architect is working on a new network design, they are expected to ensure that business requirements and technical aspects are factored in, but often there are other factors that comes into play as well Which non-business constraint must also be considered throughout the design phase?

Refer to the table.

A customer investigates connectivity options for a DCI between two production data centers to aid a large-scale migration project. The solution must provide a single 10G connection between locations and be able to run its own varying QoS profiles without service provider interaction based on the migration stages. All connectivity methods are at 10 Gbps. Which transport technology costs the least if the connectivity is required for just one year?

Company XYZ has a multicast domain that spans across multiple autonomous systems. The company wants to choose a technology that provides simplified and controlled approach to interconnecting the multicast domains. Which technology is the best fit for this purpose?

An architect designs a multi-controller network architecture with these requirements:
Achieve fast failover to control traffic when controllers fail.
Yield a short distance and high resiliency in the connection between the switches and the controller.
Reduce connectivity loss and enable smart recovery to improve the SDN survivability.
Improve connectivity by adding path diversity and capacity awareness for controllers.
Which control plane component of the multi-controller must be built to meet the requirements?
