In object-oriented programming, what concept involves hiding the internal states and requiring all interaction to be performed through well-defined interfaces?
- Abstraction
- Encapsulation
- Inheritance
- Polymorphism
'Encapsulation' is a key concept in object-oriented programming that involves bundling the internal state and methods into a single unit (a class) and allowing interaction through well-defined interfaces, thus hiding implementation details.
Which ITSM process aims to minimize the negative impact of changes to the IT infrastructure?
- Asset Management
- Change Management
- Incident Management
- Problem Management
'Change Management' in ITSM focuses on controlling and managing changes to the IT infrastructure. It aims to minimize the negative impact of changes, ensuring that they are planned and implemented effectively.
In IT governance, the principle that ensures stakeholders' rights are protected and taken into consideration is called _______.
- Accountability
- Compliance
- Equity
- Transparency
In IT governance, the principle that ensures stakeholders' rights are protected and taken into consideration is 'equity.' This means that the interests and concerns of all stakeholders are fairly addressed, promoting fairness and inclusivity.
The process of gathering information about a target system to find vulnerabilities that can be exploited is called _______.
- Debugging
- Encryption
- Hacking
- Scanning
The process of gathering information about a target system to find vulnerabilities is known as 'Scanning.' It's a critical phase in penetration testing and security assessment.
In a O(nlog?n) sorting algorithm, the log?n typically indicates the use of a _______ process.
- Divide and Conquer
- Linear
- Parallel
- Recursive
In a sorting algorithm with a time complexity of O(nlog?n), the log?n typically indicates the use of a 'Divide and Conquer' process, where the problem is split into smaller subproblems and solved recursively.
In HPC, the practice of splitting a single task into smaller tasks that run simultaneously across multiple processors is called _______.
- Clustering
- Multithreading
- Parallelism
- Virtualization
In High-Performance Computing (HPC), 'parallelism' is the technique of dividing a single task into smaller tasks that can run concurrently across multiple processors or cores, improving performance.
A neural network with three or more layers (input, output, and one or more hidden layers) is termed as a __________.
- Deep Learning Network
- Feedforward Network
- Perceptron
- Recurrent Network
A neural network with three or more layers, including input, output, and one or more hidden layers, is termed as a "Deep Learning Network." Deep networks are known for their ability to model complex relationships.
In deep learning, when the internal states of a neural network capture necessary information about previous time steps, it is particularly referred to as _______.
- Backpropagation
- Convolutional Layer
- Long Short-Term Memory
- Recurrent Neural Network
The term you're referring to is 'Recurrent Neural Network' (RNN). RNNs are designed to capture information from previous time steps, making them suitable for sequential data tasks like natural language processing and time series analysis.
An essential consideration for IoT security is ensuring the _______ of data as it is transferred from devices to servers.
- Availability
- Confidentiality
- Integrity
- Performance
IoT security requires data 'Integrity' to ensure that data remains unchanged during transmission from IoT devices to servers, preventing data tampering.
A project manager receives feedback from the quality team that certain features do not meet the quality standards. What should be the project manager's immediate step?
- Blame the quality team for the issues.
- Ignore the feedback and proceed with the project.
- Prioritize the project's schedule over quality.
- Review and address the quality issues.
When a project manager receives feedback from the quality team indicating quality issues, the immediate step should be to review and address these issues. Ignoring quality concerns can lead to project failure or costly rework later. It's crucial to ensure that the project meets the required quality standards to deliver a successful outcome.
