CAIP Certnexus Latest Version 2024/2025Which of the following concepts refers to actionable intelligence?
Wisdom
Data
Knowledge
Information Answer: Knowledge
Knowledge is actionable intelligence because it can reveal some action that must be taken.
You have a dataset of customer information, such as a customer's location, spending habits, product
reviews, and so forth. While you don't have anything specific to predict, you want to engage in customer
segmentation so that customers with similarities are considered a unified audience in your targeted
marketing campaigns. Which type of machine learning outcome is most appropriate for this situation?
Dimensionality reduction
Classification
Regression
Clustering Answer: Clustering
Clustering is a type of unsupervised learning that groups together data points with similarities, and is
therefore an excellent outcome when the goal is customer segmentation.
Which of the following describes the relationship between a machine learning model and a machine
learning algorithm?
A machine learning model represents the input data before it is fed into a machine learning algorithm.
A machine learning model generates a machine learning algorithm through training.
A machine learning model is the sum of multiple machine learning algorithms.
A machine learning model is created by applying a machine learning algorithm to input data. Answer:
A machine learning model is created by applying a machine learning algorithm to input data.
,The algorithm is a set of rules upon which the model is built. The model uses these rules to estimate
something about the world through available data. Think of an algorithm as a blueprint or recipe, and
the model as the finished building when given resources or the finished meal when given ingredients.
What does it mean for a machine learning model to be "stochastic"? Answer: The same input can
produce different outputs over multiple training sessions.
Which of the following is a Python tool that provides a frontend environment to the TensorFlow deep
learning library?
SciPy
Apache Spark MLlib
Keras
PyTorch Answer: Keras
Keras is a high-level interface into TensorFlow, and is particularly useful for beginners new to deep
learning.
SciPy is a component of the Python data science stack that provides mathematical functions, not a
frontend to TensorFlow.
PyTorch is a deep learning library that is similar to TensorFlow, but it is not a frontend to TensorFlow.
Apache Spark MLlib is a framework for machine learning that leverages clustering computing, not a
frontend to TensorFlow.
Which of the following cloud services is used as a teaching tool for reinforcement learning?
AWS DeepRacer
Cloud AutoML
Watson OpenScale
Azure Databricks Answer: AWS DeepRacer
AWS DeepRacer promotes reinforcement learning to beginners by enabling them to train a toy race car.
Watson OpenScale is an enterprise-grade AI project management platform, not a service that teaches
reinforcement learning to beginners.
, Cloud AutoML is a managed machine learning service that is beginner friendly, but it doesn't promote
reinforcement learning in particular.
Azure Databricks is a managed machine learning and deep learning service, not a service that teaches
reinforcement learning to beginners.
Which of the following graphics processing units (GPUs) supports the proprietary Compute Unified
Device Architecture (CUDA) used in applications like deep learning?
Intel Xe series
ARM Mali series
Nvidia GeForce series
AMD RX series Answer: Nvidia GeForce series
CUDA is a proprietary Nvidia standard, and is usable by modern GPUs in the GeForce line.
AMD GPUs do not support CUDA.
Attrition bias Answer: occurs when participants drop out of a long-term experiment or study
prejudice, bias Answer: a result of training data that is influenced by cultural or other stereotypes
Which of the following is an example of an inference attack?
A customer database includes name and address information. An attacker is able to find the address of a
specific customer just by looking up their name.
An account database includes user names and cryptographically secured passwords. An attacker finds a
database on the Internet that matches plaintext passwords with their secured versions, enabling the
attacker to steal users' credentials.
A donation contact list for a political candidate is filtered to only show people from a particular area
code. However, an attacker is able to reverse this filter to see the entire list of contacts, regardless of
area code.
An employee database is sorted by salary, but those salary figures have since been removed. Still, an
attacker is able to figure out how much money a specific employee makes. Answer: An employee
