Provides a trusted mechanism for verifying identities and preventing unauthorized access.

Why Other Options Are Incorrect:

Option A (Monitors enclosures): Not related to public key verification.

Option B (Protects against encrypted attacks): While encryption enhances security, it is not the purpose of a trusted third party.

Option D (Features full-time monitoring): Not a function of trusted third parties like CAs.

Each service in SOA is designed to perform a specific business function and can be reused across different applications or processes.

How SOA Enhances Agility:

By aligning business needs with IT capabilities, SOA allows organizations to quickly adapt to changing requirements.

Services can be reused or combined to support new business processes without extensive redevelopment.

Why Other Options Are Incorrect:

Option A: Breaking projects into phases aligns with agile methodologies, not SOA.

Option C: Strict adherence to a sequence is characteristic of the waterfall approach, not SOA.

Option D: Building small-scale models refers to prototyping, not SOA.

Advantage of Prototyping:

Prototyping allows teams to identify and resolve issues, such as coding errors, early in the development process.

This minimizes the risk of errors propagating into later stages.

Scenario Application:

The team detected a menu functionality issue in the prototype, revised the code, and presented an updated version.

This demonstrates the value of early error detection through prototyping.

Why Other Options Are Incorrect:

Option A: Prototypes are not static examples.

Option B: Prototypes are not project blueprints.

Option D: Prototyping is not about creating development instructions.
