Question 70

A public-sector support proof of value involves Artificial intelligence and a need to make software perform a reasoning or perception task that normally benefits from human intelligence. Which plan would provide useful approval evidence?

  1. Prioritize Generative AI because generative models synthesize new outputs using patterns learned during training and prompt context, even if the original requirement is not tested.
  2. Switch to Machine learning because it can improve predictions by learning statistical patterns from historical examples; treat this as equivalent to the original acceptance criterion.
  3. Choose Deep learning and measure only how well it can learn layered representations of complex signals such as images or speech, rather than checking the requested result.
  4. Use Artificial intelligence for the stated objective, based on its operating mechanism; test the limitation that not every AI system learns a model from data; rules-based reasoning can also be AI.

Explanation

Correct Answer

D:

For a public-sector support acceptance decision, the evaluation must measure results against the goal to make software perform a reasoning or perception task that normally benefits from human intelligence, not merely test API accessibility. Since AI is the umbrella discipline for computational perception, reasoning, decision support and learning, the test should verify the caveat that not every AI system learns a model from data; rules-based reasoning can also be AI.

Incorrect Answers

A:

A pilot of Generative AI, whose operating mechanism is that generative models synthesize new outputs using patterns learned during training and prompt context, would test its separate requirement to create original-seeming text, imagery or other content in response to a user request; it would not demonstrate Artificial intelligence's ability to make software perform a reasoning or perception task that normally benefits from human intelligence in public-sector support, especially without checking the boundary that not every AI system learns a model from data; rules-based reasoning can also be AI.

B:

A pilot of Machine learning, whose operating mechanism is that ML learns relationships from data rather than requiring a programmer to encode each decision as a fixed rule, would test its separate requirement to improve predictions by learning statistical patterns from historical examples; it would not demonstrate Artificial intelligence's ability to make software perform a reasoning or perception task that normally benefits from human intelligence in public-sector support, especially without checking the boundary that not every AI system learns a model from data; rules-based reasoning can also be AI.

C:

A pilot of Deep learning, whose operating mechanism is that multilayer neural networks learn progressively more abstract features from data, would test its separate requirement to learn layered representations of complex signals such as images or speech; it would not demonstrate Artificial intelligence's ability to make software perform a reasoning or perception task that normally benefits from human intelligence in public-sector support, especially without checking the boundary that not every AI system learns a model from data; rules-based reasoning can also be AI.

Question 71

An online retail reviewer asks for a test of Real-time inference against the goal to return a risk score while a checkout request is still waiting. Which proposal respects the known boundary?

  1. Use Real-time inference for the stated objective, based on its operating mechanism; test the limitation that continuously serving requests can cost more than periodic bulk processing.
  2. Prioritize Asynchronous inference because the request is queued and processed separately from the initial client connection, even if the original requirement is not tested.
  3. Switch to Serverless inference because it can serve sporadic prediction traffic without provisioning a constantly running endpoint; treat this as equivalent to the original acceptance criterion.
  4. Choose Batch inference and measure only how well it can score a large backlog of customer records overnight without per-record response deadlines, rather than checking the requested result.

Explanation

Correct Answer

A:

For an online retail acceptance decision, the evaluation must measure results against the goal to return a risk score while a checkout request is still waiting, not merely test API accessibility. Since an online endpoint responds to individual requests with low latency, the test should verify the caveat that continuously serving requests can cost more than periodic bulk processing.

Incorrect Answers

B:

A pilot of Asynchronous inference, whose operating mechanism is that the request is queued and processed separately from the initial client connection, would test its separate requirement to accept a large inference request quickly and deliver its result later; it would not demonstrate Real-time inference's ability to return a risk score while a checkout request is still waiting in online retail, especially without checking the boundary that continuously serving requests can cost more than periodic bulk processing.

C:

A pilot of Serverless inference, whose operating mechanism is that managed on-demand compute scales inference resources with incoming demand, would test its separate requirement to serve sporadic prediction traffic without provisioning a constantly running endpoint; it would not demonstrate Real-time inference's ability to return a risk score while a checkout request is still waiting in online retail, especially without checking the boundary that continuously serving requests can cost more than periodic bulk processing.

D:

A pilot of Batch inference, whose operating mechanism is that batch prediction handles collections of inputs in scheduled or asynchronous jobs, would test its separate requirement to score a large backlog of customer records overnight without per-record response deadlines; it would not demonstrate Real-time inference's ability to return a risk score while a checkout request is still waiting in online retail, especially without checking the boundary that continuously serving requests can cost more than periodic bulk processing.

Question 72

Before expanding Reinforcement learning in travel services, the team needs evidence that it can improve a sequence of choices using rewards from an environment. Which pilot plan checks capability and limits together?

  1. Prioritize Generative AI because generative models synthesize new outputs using patterns learned during training and prompt context, even if the original requirement is not tested.
  2. Choose Supervised learning and measure only how well it can predict a known target using examples paired with correct outcomes, rather than checking the requested result.
  3. Use Reinforcement learning for the stated objective, based on its operating mechanism; test the limitation that reward design and exploration may create unsafe behavior without constraints.
  4. Switch to Unsupervised learning because it can discover natural patterns in customer behavior without preassigned classes; treat this as equivalent to the original acceptance criterion.

Explanation

Correct Answer

C:

For a travel services acceptance decision, the evaluation must measure results against the goal to improve a sequence of choices using rewards from an environment, not merely test API accessibility. Since an agent learns a policy by balancing decisions and feedback over time, the test should verify the caveat that reward design and exploration may create unsafe behavior without constraints.

Incorrect Answers

A:

A pilot of Generative AI, whose operating mechanism is that generative models synthesize new outputs using patterns learned during training and prompt context, would test its separate requirement to create original-seeming text, imagery or other content in response to a user request; it would not demonstrate Reinforcement learning's ability to improve a sequence of choices using rewards from an environment in travel services, especially without checking the boundary that reward design and exploration may create unsafe behavior without constraints.

B:

A pilot of Supervised learning, whose operating mechanism is that training learns a mapping between features and labeled results, would test its separate requirement to predict a known target using examples paired with correct outcomes; it would not demonstrate Reinforcement learning's ability to improve a sequence of choices using rewards from an environment in travel services, especially without checking the boundary that reward design and exploration may create unsafe behavior without constraints.

D:

A pilot of Unsupervised learning, whose operating mechanism is that an algorithm groups or represents observations using their similarity or structure, would test its separate requirement to discover natural patterns in customer behavior without preassigned classes; it would not demonstrate Reinforcement learning's ability to improve a sequence of choices using rewards from an environment in travel services, especially without checking the boundary that reward design and exploration may create unsafe behavior without constraints.

Question 73

For a telecommunications assessment of Agentic AI, the stated goal is to plan a task, select tools and take bounded actions toward a user goal. Select TWO correct statements about how the concept works or is limited. (Choose TWO.)

  1. Agentic AI operates according to this purported mechanism: multilayer neural networks learn progressively more abstract features from data.
  2. The described method removes the need to consider the stated limitation because ML learns relationships from data rather than requiring a programmer to encode each decision as a fixed rule.
  3. The main purpose of Agentic AI is to create original-seeming text, imagery or other content in response to a user request instead of to plan a task, select tools and take bounded actions toward a user goal.
  4. Tool authorization, action approval and monitoring still need explicit controls.
  5. An agent can orchestrate reasoning, memory and external tool calls across multiple steps.

Explanation

Correct Answers

D:

This is a valid caution for Agentic AI: tool authorization, action approval and monitoring still need explicit controls. In a telecommunications setting, the concern follows even when an agent can orchestrate reasoning, memory and external tool calls across multiple steps; it must be checked against the particular requirement to plan a task, select tools and take bounded actions toward a user goal.

E:

This accurately identifies the operation behind Agentic AI: an agent can orchestrate reasoning, memory and external tool calls across multiple steps. It offers the mechanism needed to plan a task, select tools and take bounded actions toward a user goal in the telecommunications example, with the boundary that tool authorization, action approval and monitoring still need explicit controls.

Incorrect Answers

A:

The stated behavior is for Deep learning, not for Agentic AI in a telecommunications requirement to plan a task, select tools and take bounded actions toward a user goal. Multilayer neural networks learn progressively more abstract features from data is a real capability of the alternative, whereas the concept under review works because an agent can orchestrate reasoning, memory and external tool calls across multiple steps.

B:

This assertion incorrectly waives the limitation of Agentic AI in the telecommunications context. The relevant boundary is that tool authorization, action approval and monitoring still need explicit controls; selecting a technology to plan a task, select tools and take bounded actions toward a user goal does not remove that underlying requirement.

C:

The stated behavior is for Generative AI, not for Agentic AI in a telecommunications requirement to plan a task, select tools and take bounded actions toward a user goal. Generative models synthesize new outputs using patterns learned during training and prompt context is a real capability of the alternative, whereas the concept under review works because an agent can orchestrate reasoning, memory and external tool calls across multiple steps.
