A _______ is a virtualized storage model that pools physical storage from multiple network storage devices and makes it appear as if it's a single storage device.
- DNS
- NAS
- RAID
- SAN
A 'SAN' (Storage Area Network) is a virtualized storage model that combines physical storage from various network storage devices into a single storage device. It provides high-speed data access and centralized storage management.
What does RAID stand for in terms of data storage?
- Random Access and Integrated Data
- Rapid Access and Integrated Devices
- Read-Write Automation and Integrated Data
- Redundant Array of Independent Disks
RAID, which stands for 'Redundant Array of Independent Disks,' is a technology used in data storage to combine multiple physical disks into a single logical unit for the purpose of data redundancy, improved performance, or both. It helps protect data from disk failures and can enhance data access speed.
In the context of ERP, what is the primary challenge of "data silos"?
- Data duplication
- Data encryption
- Data integration
- Data isolation
"Data silos" in ERP refer to isolated data repositories within an organization, and the primary challenge they pose is 'data integration.' Integrated data is essential for a holistic view of business processes and decision-making.
You are tasked with setting up a public Wi-Fi network for a cafe. Which security measure would be most appropriate to prevent users from seeing the traffic of other users?
- Intrusion Detection System
- MAC Filtering
- VPN Configuration
- WPA3 Encryption
Utilizing WPA3 (Wi-Fi Protected Access 3) encryption is a crucial security measure for a public Wi-Fi network. It encrypts the data between the user's device and the access point, preventing other users from intercepting or seeing the traffic.
A project's _______ defines the work that needs to be accomplished to deliver a product, service, or result with the specified features and functions.
- Milestone
- Risk Register
- Scope Statement
- Stakeholder Analysis
The 'scope statement' in a project defines the work that must be completed to deliver the project's intended product, service, or result with specified features and functions. It sets the boundaries for the project and helps manage expectations. Milestones are significant project events, the Risk Register records project risks, and Stakeholder Analysis involves identifying and assessing stakeholders.
Which technique helps prevent overfitting by ignoring certain neurons during training?
- Batch Normalization
- Dropout
- Gradient Clipping
- ReLU Activation Function
The technique that helps prevent overfitting by ignoring certain neurons during training is 'Dropout.' It randomly deactivates neurons, forcing the network to learn more robust representations.
What term is used to describe a collection of data elements that have a specific order and can be indexed?
- Array
- Function
- String
- Variable
An 'array' is a data structure in programming that allows you to store a collection of data elements in a specific order. Each element in an array can be accessed using an index, which is a numerical reference. Arrays are commonly used for organizing and manipulating data efficiently.

Which architectural pattern in mobile app development separates an application's UI, data, and logic into three separate layers?
- Factory Method Pattern
- Model-View-Controller (MVC)
- Observer Pattern
- Singleton Pattern
The Model-View-Controller (MVC) architectural pattern separates a mobile app into three interconnected components: Model (data and logic), View (UI), and Controller (manages user input). This separation enhances code maintainability and scalability in app development.
Which term refers to the practice of writing code in short, consistent cycles, often with paired programming and frequent communication with stakeholders?
- Agile Development
- Big Bang Integration Testing
- Code Refactoring
- Waterfall Methodology
'Agile Development' is a software development approach that involves writing code in short, consistent cycles called iterations or sprints. It emphasizes collaboration with stakeholders, adaptability, and continuous delivery.
