A type of regularization technique that adds a penalty to the loss function for large weights is called _______.
- Activation Function
- Dropout
- Gradient Descent
- L1 Regularization
The technique you're describing is 'L1 Regularization.' It adds a penalty term to the loss function for large weights, encouraging the model to use only the most important features and prevent overfitting.
Which concept in IT governance emphasizes the importance of decision rights and accountability to encourage desirable behavior in the use of IT?
- API (Application Programming Interface)
- COBIT (Control Objectives for Information and Related Technologies)
- ITIL (Information Technology Infrastructure Library)
- SIEM (Security Information and Event Management)
In IT governance, 'COBIT' (Control Objectives for Information and Related Technologies) is a framework that emphasizes decision rights, accountability, and governance to ensure that IT is used in a way that aligns with business objectives and encourages desirable behavior.
Which protocol is often used for lightweight communication in IoT devices due to its low power consumption?
- FTP (File Transfer Protocol)
- HTTP (Hypertext Transfer Protocol)
- MQTT (Message Queuing Telemetry Transport)
- TCP (Transmission Control Protocol)
MQTT is widely used in IoT because it's designed for low-power, efficient communication. MQTT's publish-subscribe model minimizes overhead and is well-suited for resource-constrained devices.
Which type of penetration testing focuses on testing from an attacker's perspective without prior knowledge of the target infrastructure?
- Black-Box Testing
- Gray-Box Testing
- Vulnerability Scanning
- White-Box Testing
'Black-Box Testing' is a type of penetration testing where testers simulate an attacker with no prior knowledge of the target infrastructure. The goal is to identify vulnerabilities as if they were an external attacker.
Which type of attack involves intercepting and possibly altering communications between two parties without their knowledge?
- DDoS Attack
- Malware
- Man-in-the-Middle Attack
- Phishing
A 'Man-in-the-Middle (MitM) Attack' is a form of cyberattack where an attacker intercepts and possibly alters communications between two parties without their knowledge, compromising data integrity and privacy.
What is the main difference between a shallow neural network and a deep neural network?
- Activation Function
- Learning Rate
- Number of Layers
- Number of Neurons
The main difference between a shallow neural network and a deep neural network is the 'number of layers.' Shallow networks have only a few layers, while deep networks have many hidden layers.
In IT governance, the framework that provides a reference model to organize IT processes and consider their governance is known as _______.
- Agile
- COBIT
- DevOps
- ITIL
COBIT (Control Objectives for Information and Related Technologies) is a widely used framework for IT governance. It provides a set of best practices and standards to organize and govern IT processes, ensuring they align with business goals.
An embedded system, like a microwave or a washing machine, needs an operating system. What type of OS would be most suitable for such systems?
- Linux
- Real-time Operating System (RTOS)
- Windows OS
- macOS
Embedded systems, like microwaves or washing machines, benefit from a 'Real-time Operating System (RTOS)' because it provides predictable and timely responses, essential for control and automation in such devices.
Company wants to analyze images to detect defects in products on an assembly line. Which type of neural network would be most suitable for this task?
- Convolutional Neural Network (CNN)
- Deep Q-Network (DQN)
- Generative Adversarial Network (GAN)
- Recurrent Neural Network (RNN)
For image analysis and object detection tasks, a 'Convolutional Neural Network (CNN)' is the most suitable choice. CNNs are designed to effectively process grid-like data, making them ideal for tasks like defect detection in images. They excel at identifying patterns and features in images.
In cloud environments, the service that automatically distributes incoming traffic across multiple targets is termed _______.
- DNS
- Firewall
- Load Balancer
- Proxy Server
A 'Load Balancer' is a crucial service in cloud environments that evenly distributes incoming network traffic across multiple targets, enhancing performance, availability, and reliability.
