What is the primary purpose of a cloud-based data lake?
- Managing cloud resources
- Running virtual machines
- Storing structured data
- Storing unstructured data
A cloud-based data lake is primarily used for storing unstructured data like raw text, images, audio, or log files, enabling flexible and scalable data storage for later processing and analysis.
The ________ migration strategy is also known as the "rehosting" approach.
- Re-architecting
- Re-engineering
- Re-hosting
- Re-platforming
The "rehosting" strategy, often referred to as the "lift-and-shift" approach, involves moving applications to the cloud without major modifications.
Middleware that provides a set of services to authenticate, authorize, and account users is known as ________.
- Communication Middleware
- Identity Middleware
- Security Middleware
- Transaction Middleware
Identity Middleware is responsible for authenticating users, authorizing their access, and accounting for their activities. It ensures secure user management.
Which of the following is a primary benefit of using SaaS?
- Complex software development
- Cost-effectiveness and scalability.
- High hardware maintenance cost
- Latency in accessing software.
A primary benefit of SaaS is cost-effectiveness and scalability. Users avoid high upfront costs and can easily scale their usage as needed.
Account hijacking can lead to which of the following unauthorized actions?
- Enhanced User Experience
- Improved Application Performance
- Increased Cloud Storage
- Unauthorized Data Access
Account hijacking can lead to unauthorized access to data, which can result in data breaches and loss of sensitive information.
Virtualization that requires modifications to the guest operating system to communicate with the underlying hardware is known as ________.
- Full Virtualization
- Hardware Virtualization
- Paravirtualization
- Software Virtualization
Paravirtualization is a form of virtualization that requires modifications to the guest OS to improve performance and communication with the underlying hardware. It offers enhanced efficiency but requires OS modifications.
An organization is deploying a new application and wants to ensure they have visibility into its performance, uptime, and any potential issues. Which kind of tool would be most suitable for this purpose?
- Application Performance Monitoring Tool
- Data Backup and Recovery Tool
- Database Management Tool
- Project Management Software
An Application Performance Monitoring Tool is essential for real-time monitoring, analysis, and reporting of an application's performance, ensuring that the organization has visibility into uptime, performance metrics, and potential issues, which is crucial for maintaining a reliable application.
Which of the following is NOT a characteristic of cloud computing?
- Broad Network Access
- High Latency
- On-Demand Scalability
- Self-Service Provisioning
High latency is NOT a characteristic of cloud computing. Cloud services aim for low latency, providing quick access to resources over the network.
Cloud computing is primarily about:
- Delivering computing services over the internet
- Managing office supplies
- Running video game tournaments
- Writing computer code
Cloud computing is primarily focused on delivering computing services, such as servers, databases, and applications, over the internet, rather than managing supplies, gaming, or coding.
A network administrator wants to simulate a complex network topology without buying additional hardware components. Which virtualization approach should they consider?
- Network Emulation
- Network Virtualization
- Server Virtualization
- Storage Virtualization
Network emulation allows the simulation of complex network topologies using software, eliminating the need to buy additional hardware, making it an efficient choice for the network administrator.
