NEW QUESTION # 217
Various teams in different organizations within an enterprise are preparing low-level design documents using a Waterfall project model. Input from relevant stakeholders was captured at the start of the project, and the scope has been defined. What impact will it have if stakeholders ask for changes before documentation is complete?

• A. This provides more opportunity to think outside the box.
• B. Rework is expected before the delivery.
• C. Significant effort and time are required.
• D. This provides a flexible approach to incorporate changes.

Answer: C

Explanation:
* C (Significant effort and time): In a Waterfall model, changes introduced after the design phase require rework of multiple design documents, validations, and downstream impacts on implementation and testing. This leads to significant delays and resource consumption compared to more flexible models like Agile.
Other options explained:
* A: Creativity is not the primary impact.
* B: Rework is true but doesn't fully capture the scope of additional effort.
* D: Waterfall does not provide inherent flexibility to absorb late changes.

NEW QUESTION # 219
What is an advantage of using Agile over waterfall methodology in the network design lifecycle?

• A. Closed loop operation.
• B. Lower total cost.
• C. Reduced risk in the design process.
• D. ideal for large projects.

Answer: C

Explanation:
Agile uses short, iterative cycles and continuous feedback so design issues are found and corrected early, reducing overall risk compared to a big-bang Waterfall approach.
Waterfall tends to have higher risk because mistakes are discovered late, after large design and implementation phases.

NEW QUESTION # 220
An enterprise has no direct control over a public cloud architecture. What is the limitation of the cloud integration approach of creating a unified elastic resource pool of data center and cloud functions?

• A. suitable for small size dataset
• B. time consuming to implement
• C. sporadic integration
• D. less flexible

Answer: C

Explanation:
Since the enterprise has no direct control over the public cloud architecture, integration between the on-premises data center and the cloud cannot be continuous or seamless. This leads to sporadic integration, which limits the effectiveness of creating a unified elastic resource pool.

Which development model is closely associated with traditional project management?

• A. Agile model
• B. Evolutionary delivery model
• C. Lifecycle model
• D. Static model
