If an organization is looking to capitalize on the cloud-native features, such as serverless computing or managed database services, which migration strategy would be most appropriate?
- Rearchitect (rebuild)
- Refactor (re-architect)
- Rehost (lift and shift)
- Repurchase (buy a new one)
Rearchitecting (rebuilding) an application allows the organization to optimize it for cloud-native features, making it the most suitable strategy to capitalize on such features.
Which of the following is a key benefit of using Google Cloud Functions?
- Complex Infrastructure Setup
- High Initial Cost
- Large Virtual Machines
- Serverless Computing
Google Cloud Functions provide serverless computing, which means developers can focus on code without worrying about infrastructure. This results in cost savings and scalability.
In terms of Machine Learning services in the cloud, what is the primary advantage of using "transfer learning"?
- Enhanced data storage
- Improved model accuracy
- Reduced training time
- Simplified deployment
The primary advantage of using transfer learning in cloud-based ML is improved model accuracy. It allows leveraging pre-trained models, making it easier to achieve high accuracy with limited data.
Which type of cloud is typically used by a single organization and is not shared with others?
- Private Cloud
- Public Cloud
- Hybrid Cloud
- Community Cloud
A "Private Cloud" is typically used by a single organization and is not shared with others. It offers more control and customization options but may require more resources for setup and maintenance.
Which of the following best describes Type-1 (bare-metal) hypervisors?
- They are primarily used for development and testing environments.
- They rely on Type-2 hypervisors for operation.
- They require a full-fledged operating system to function properly.
- They run directly on the physical hardware, without the need for an underlying operating system.
Type-1 (bare-metal) hypervisors operate directly on the hardware, eliminating the need for an underlying OS, which provides better performance and security for virtual machines.
Which aspect of SaaS can be a potential concern for businesses with stringent data residency requirements?
- Data Backup Strategy
- Data Encryption
- Data Location
- Data Security
For businesses with stringent data residency requirements, the location of data in a SaaS solution can be a significant concern. They need to ensure that their data remains within specified geographical boundaries or jurisdictions.
A company has just deployed a new cloud-based application. The users interact with the application through a web browser, but they report that sometimes the application is slow. While the front end appears fine, where would you start investigating for potential issues?
- Backend server performance tuning
- Browser cache analysis
- Database optimization
- Network latency check
In this scenario, the slowdown issue is likely in the backend. Starting with backend server performance tuning is a key step to address the problem.
In a cloud scenario, if an attacker gains control over a user's access credentials, it can lead to ________.
- Account Lockout
- Data Loss
- Resource Optimization
- Unauthorized Access
In a cloud scenario, if an attacker gains control over a user's access credentials, it can lead to "Unauthorized Access." This access can be used to compromise data, resources, or even perform malicious actions within the cloud environment.
Which of the following can be a preventive measure against data breaches caused by insider threats?
- Ignoring insider threats
- Increasing firewall strength
- Reducing the number of external threats
- Regular security training for employees
Preventive measures against insider threats include regular security training for employees to make them aware of security best practices and the risks associated with insider threats. Education can help reduce the likelihood of insider incidents.
In a data center, which type of virtualization would be used to manage and pool the physical storage from multiple network storage devices?
- Application Virtualization
- Network Virtualization
- Server Virtualization
- Storage Virtualization
Storage Virtualization is used to abstract and pool storage resources from multiple devices, allowing for centralized management and efficient use.
