In NoSQL databases, _______ is a system for storing data in flexible, schema-less documents rather than in traditional tables.
- BSON
- DocumentDB
- JSON
- XML
In NoSQL databases, data is often stored in flexible, schema-less documents, and JSON (JavaScript Object Notation) is a widely used format for this purpose. JSON allows for easy data representation and storage.
A routing technique where packets can take multiple paths to reach the destination, thus providing load balancing, is called _______.
- Anycast
- Multicast
- Multipath
- Unicast
The routing technique that allows packets to take multiple paths to reach the destination for load balancing and redundancy is known as 'Multipath' routing. This is commonly used in modern network architectures.
What type of attack involves overwhelming a target with a flood of internet traffic, rendering it inaccessible?
- Cross-Site Scripting
- DDoS attack
- Phishing attack
- SQL injection
A 'DDoS attack' (Distributed Denial of Service) is when a target is overwhelmed by a massive flood of internet traffic from multiple sources, causing it to become inaccessible. It's a common attack to disrupt online services.
In data visualization, the process of displaying three-dimensional data on a two-dimensional plane is known as _______.
- 3D Mapping
- Data Projection
- Dimension Reduction
- Flat Visualization
The process described here is 'Data Projection.' It involves transforming three-dimensional data onto a two-dimensional plane while preserving important relationships and patterns, which is crucial in data visualization and analysis.
Which ERP deployment method involves using the Internet to access software applications provided by third-party vendors?
- Cloud-Based Deployment
- Hybrid Deployment
- On-Premises Deployment
- Open-Source Deployment
'Cloud-Based Deployment' in ERP involves using the Internet to access software applications hosted by third-party vendors. This method offers scalability, cost-efficiency, and flexibility in comparison to traditional on-premises deployments.
Which tool is often used to diagnose the route packets take through the network?
- Firewall Software
- Traceroute
- Video Streaming Tool
- Word Processing Software
'Traceroute' is a network diagnostic tool used to trace the route packets take through the network. It displays the path and measures the transit times between network nodes, helping identify connectivity issues.
Which of the following best describes the primary purpose of IoT devices?
- Collect and exchange data
- Cook meals automatically
- Play video games
- Predict the weather
The primary purpose of IoT (Internet of Things) devices is to "collect and exchange data." These devices are designed to gather information from the physical world and share it over the internet for analysis and automation.
Which approach to digital transformation focuses on rapid experimentation, frequent releases, and iterative development?
- Agile
- DevOps
- Six Sigma
- Waterfall
The 'Agile' approach to digital transformation emphasizes rapid experimentation, frequent releases, and iterative development. It is a flexible methodology that adapts to changing requirements and customer feedback.
You are designing a new computer system that requires very fast temporary storage to hold data between the CPU and main memory. Which type of memory would be most appropriate?
- Cache Memory
- Hard Disk Drive (HDD)
- Optical Drive
- USB Flash Drive
The most appropriate choice for fast temporary storage between the CPU and main memory is 'Cache Memory.' It is a high-speed, volatile memory that reduces latency in data access, improving system performance.
What is the key difference between Type 1 (bare-metal) and Type 2 (hosted) hypervisors?
- Type 1 hypervisors are easier to install than Type 2 hypervisors.
- Type 1 hypervisors are more expensive than Type 2 hypervisors.
- Type 1 hypervisors are used for gaming, while Type 2 hypervisors are used for server virtualization.
- Type 1 hypervisors run directly on the physical hardware, while Type 2 hypervisors run on top of a host operating system.
The key difference is that 'Type 1 hypervisors' run directly on the physical hardware (bare-metal), while 'Type 2 hypervisors' run on top of a host operating system. Type 1 offers better performance and isolation.
