Which characteristic of cloud computing allows resources to be provisioned without human interaction?
- High Availability
- Redundancy
- Self-Service Provisioning
- Virtualization
Self-service provisioning enables users to allocate cloud resources independently, reducing the need for manual intervention in resource allocation.
A cloud infrastructure that serves a specific community with common concerns (e.g., mission, security requirements, and compliance considerations) is known as:
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
A Community Cloud is designed to serve a specific community with shared concerns like mission, security, and compliance requirements.
What is the most common cause of data breaches in organizations?
- Hardware Failure
- Human Error
- Natural Disasters
- Software Bugs
'Human Error' is the most common cause of data breaches, such as accidentally sharing sensitive information or falling for phishing attacks.
An organization is concerned about the performance overhead introduced by virtualization layers. They are considering a method where the guest OS is aware of the virtualization and can make direct calls to the physical hardware. Which virtualization technique addresses this?
- Emulation
- Full Virtualization
- Hardware-assisted Virtualization
- Paravirtualization
Paravirtualization is the technique where the guest OS is aware of virtualization and can make direct calls to the physical hardware. This minimizes the performance overhead introduced by virtualization layers.
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 analytics tools is serverless and fully managed by its cloud provider?
- Amazon Athena
- Apache Hadoop
- Microsoft SQL Server
- MongoDB Atlas
Amazon Athena is a serverless and fully managed analytics tool provided by AWS. It doesn't require infrastructure provisioning and can execute SQL queries on data stored in Amazon S3, making it a convenient choice for serverless analytics.
