Middleware often acts as a bridge between:
- Clients and databases
- Databases and files
- Hardware and software
- Users and servers
Middleware often acts as a bridge between hardware and software, ensuring seamless communication and interaction between these two components.
Which of the following is NOT typically a function of middleware?
- Data Storage and Retrieval
- Message Routing
- Security
- User Interface
Middleware primarily handles tasks like data storage and retrieval, security, and message routing. User interface management is typically outside the scope of middleware.
Which of the following scenarios is best suited for a hybrid cloud model?
- A company with a strict data residency requirement
- A research institution with high computing demands
- A small business with minimal data
- A startup looking for low costs
A hybrid cloud model is ideal for organizations with varying data residency needs, allowing them to use both public and private clouds, maintaining control over data in the private portion.
Account hijacking can lead to unauthorized data access, making it crucial to monitor and log all ________ in cloud environments.
- Activities
- Logins
- Requests
- Resources
Account hijacking can lead to unauthorized data access, making it crucial to monitor and log all "Logins" in cloud environments. Monitoring and logging login activities can help detect and respond to unauthorized access.
Which practice can potentially lead to account hijacking if not managed properly?
- Regular system backups
- Regular system updates
- Strong encryption practices
- Weak or reused passwords
Weak or reused passwords can potentially lead to account hijacking when not managed properly, as attackers can easily guess or obtain such passwords. Proper management is crucial for security.
Which of the following is NOT a major cloud service provider (CSP)?
- Azure
- IBM Cloud
- Open Source Cloud
- Oracle Cloud
IBM, Azure, and Oracle Cloud are major cloud service providers, but "Open Source Cloud" is not a CSP.
Docker is primarily used for:
- Containerization
- Hypervisor
- Orchestration
- Virtualization
Docker is primarily used for containerization, which is the process of packaging and running applications and their dependencies in isolated containers.
When an organization decides to modify or completely change the application's architecture during its migration to the cloud, which strategy is it employing?
- Refactoring (Re-architect)
- Rehosting (Lift and Shift)
- Reimagining (Full Rebuild)
- Replatforming (Lift, Tinker, and Shift)
Refactoring, or Re-architecting, involves modifying or completely redesigning the application's architecture to better leverage the cloud's advantages. It's a strategy for optimizing and improving the application during migration.
A company is looking to deploy a high-performance virtualized environment directly on server hardware without any underlying operating system. Which type of hypervisor would be most suitable?
- Container-based Hypervisor
- Paravirtualization Hypervisor
- Type 1 Hypervisor
- Type 2 Hypervisor
In this scenario, a Type 1 Hypervisor, also known as a bare-metal hypervisor, is most suitable. It runs directly on the server hardware without an underlying OS, offering high performance and minimal overhead.
The integration of IoT and cloud computing enables what kind of analysis on a vast scale?
- Descriptive analysis
- Diagnostic analysis
- Predictive analysis
- Real-time analysis
The integration of IoT and cloud computing enables predictive analysis on a vast scale. IoT devices generate large amounts of data that can be analyzed for future trends and insights.
