解析：MS AI responsibilities
• Fairness – Limit Biases
• Reliability ad Safely – ops, resist manipulating, use of regresses testing
• Privacy and security- secure data provide security controls
• Inclusiveness- AI available to everyone i.e., disabled ppl
• Transparency- fully aware of the limitations over AII in use
• Accountability- follow governments and frameworks meet legal and ethical standards

The handling of unusual or missing values provided to an AI system is a consideration for the Microsoft _________ principle for responsible AI.
A. inclusiveness
B. privacy and security
C. reliability and safety
D. transparency
答案：C
解析：https://learn.microsoft.com/en-us/azure/cloud-adoption-framework/innovate/best-practices/trusted-ai#reliability-and-safety
AI systems need to be reliable and safe in order to be trusted. It's important for a system to perform as it was originally designed and for it to respond safely to new situations. Its inherent resilience should resist intended or unintended manipulation. Rigorous testing and validation should be established for operating conditions to ensure that the system responds safely to edge cases, and A/B testing and champion/challenger methods should be integrated into the evaluation process.
You are designing an AI system that empowers everyone, including people who have hearing, visual, and other impairments.
This is an example of which Microsoft guiding principle for responsible AI?
A. fairness
B. inclusiveness
C. reliability and safety
D. accountability
答案：B
解析：https://learn.microsoft.com/en-us/azure/cloud-adoption-framework/innovate/best-practices/trusted-ai#inclusiveness
Inclusiveness mandates that AI should consider all human races and experiences, and inclusive design practices can help developers to understand and address potential barriers that could unintentionally exclude people. Where possible, speech-to-text, text-to-speech, and visual recognition technology should be used to empower people with hearing, visual, and other impairments.

When developing an AI system for self-driving cars, the Microsoft _________ principle for responsible Al should be applied to ensure consistent operation of the system during unexpected circumstances.
A. inclusiveness
B. accountability
C. reliability and safety
D. fairness
答案：C
解析：Reliability and safety: To build trust, it's critical that AI systems operate reliably, safely, and consistently under normal circumstances and in unexpected conditions.
These systems should be able to operate as they were originally designed, respond safely to unanticipated conditions, and resist harmful manipulation.

Returning a bounding box that indicates the location of a vehicle in an image is an example of _________.
A. image classification.
B. object detection.
C. optical character recognizer (OCR)
D. semantic segmentation.
答案：B
解析：https://learn.microsoft.com/en-us/azure/cognitive-services/computer-vision/concept-object-detection
Object detection is similar to tagging, but the API returns the bounding box coordinates (in pixels) for each object found in the image. For example, if an image contains a dog, cat and person, the Detect operation will list those objects with their coordinates in the image. You can use this functionality to process the relationships between the objects in an image. It also lets you determine whether there are multiple instances of the same object in an image.
