When designing the Logical Design of an NSX-T Data Center solution, it is important to distinguish between technical and non-technical requirements. Non-technical requirements generally refer to business needs that do not involve specific technical details. The statement 'Any solution should add more value to current and future customer engagements' focuses on the business value and customer interactions, which are non-technical aspects. Similarly, 'The design should offer agility and freedom for application phases' emphasizes flexibility and adaptability in the application lifecycle, which is also a non-technical requirement. The other options, such as concerns about hardcoded IP addresses, business continuity plans based on specific technologies, and the use of different vendors for storage solutions, involve technical considerations and constraints.
