Cisco Updated 400-007 Exam Questions and Answers by alannah

In IoT environments, especially in manufacturing plants, security is the primary concern during migration:

IoT devices often have limited security capabilities and may introduce vulnerabilities if not properly segmented, authenticated, and monitored.

Manufacturing plants operate critical systems where availability, safety, and integrity are paramount.

CCDE v3.1 emphasizes securing data, devices, and control systems as a top priority during IoT migrations.

Other options explained:

A: Sensors are part of the IoT solution but not the primary migration concern.

C: Applications are important but typically come after securing connectivity and endpoints.

D/E: Infrastructure elements are secondary to security in the migration assessment.

—

A (SD-WAN):SDN principles are widely adopted in wide area networks for dynamic path selection, centralized control, and policy enforcement.

B (Mobile networks):5G and modern mobile networks leverage SDN/NFV architectures to virtualize core services and optimize resource utilization.

Other options explained:

C: Metro networks adopt SDN, but WAN and mobile are more common mainstream use cases.

D/E: Application and control network are not direct SDN network types.

B (Strategic planning): Long-term business-aligned decisions that shape future infrastructure needs.

D (Tactical planning): Short-to-mid-term activities that adjust design based on evolving operational realities, constraints, and priorities.

Why other options are incorrect:

A and E: While cost and business optimization are goals, they are not defined planning approaches.

C: Modular is a design methodology, not a planning approach.
