Which two types of planning approaches are used to develop business-driven network designs and to facilitate the design decisions? (Choose two)

Cost optimization is a design consideration or constraint, not a formal planning approach used to develop and facilitate network design decisions.

Strategic planning defines the long-term business goals, architectural direction, and high-level technology roadmap that drive network design decisions at an organizational level.

Modular approach refers to a network design pattern (using discrete building blocks), not a planning methodology used to drive business-aligned design decisions.

Tactical planning translates the strategic direction into specific, actionable near-term design and implementation steps, addressing immediate technical requirements and design trade-offs.

Business optimization is a general goal or outcome, not a recognized planning approach in network design methodology frameworks.
