In the context of cloud computing, what does the "elasticity" characteristic ensure?
- Data Encryption
- Dynamic Scalability
- Redundancy Management
- Resource Efficiency
Elasticity in cloud computing refers to the ability to dynamically and automatically scale resources up or down in response to changing workloads. It ensures efficient resource allocation, cost savings, and performance optimization.
Which cloud migration strategy involves moving an application from an on-premises environment to the cloud without making changes to its architecture?
- Refactoring (Re-architect)
- Rehosting (Lift and Shift)
- Reimagining (Full Rebuild)
- Replatforming (Lift, Tinker, and Shift)
Rehosting, also known as Lift and Shift, is a migration strategy where you move the application to the cloud as-is, without making significant architectural changes. It's a quick way to get to the cloud, but it might not fully optimize the cloud's capabilities.
During the ________ process, an application might be decomposed and reassembled using cloud-native features for better performance and scalability.
- Rebuilding
- Refactoring
- Rehosting
- Replatforming
The blank should be filled with "Refactoring." Refactoring involves restructuring or optimizing an application for cloud-native features, leading to improved performance and scalability.
What is the primary purpose of cloud monitoring tools?
- Data Storage
- Monitoring and Reporting
- Server Deployment
- Virtualization
Cloud monitoring tools primarily serve the purpose of monitoring and reporting the performance, availability, and usage of cloud resources.
How does data interoperability in a hybrid cloud model differ from other cloud deployment models?
- Data Isolation
- Limited Data Portability
- No Data Interoperability
- Seamless Data Exchange Across Environments
In a hybrid cloud, data interoperability enables seamless exchange of data across public and private cloud environments, differing from other models with limited data portability.
Which of the following is a core component of Docker?
- Docker Engine
- Docker Hub
- Docker Registry
- Kubernetes
The Docker Engine is a core component of Docker that is responsible for building, running, and managing containers on a host system.
In a SaaS model, the responsibility for software updates and patch management primarily lies with:
- A Third Party
- It's Shared Between All
- The End-User
- The SaaS Provider
In a SaaS (Software as a Service) model, the primary responsibility for software updates and patch management lies with the SaaS provider. This is a key benefit of SaaS, as it relieves the end-users of this task.
AWS Lambda and Azure Functions are primarily used for which type of computing?
- Cloud Computing (Option 3)
- Distributed Computing (Option 4)
- Edge Computing (Option 2)
- Serverless Computing (Option 1)
AWS Lambda and Azure Functions are both primarily used for Serverless Computing, where you can run code without managing servers, scaling automatically, and paying only for what you use.
One of the primary reasons to implement CI/CD in cloud environments is to:
- Accelerate Software Delivery
- Ensure Legacy System Compatibility
- Implement Strong Security Practices
- Reduce Cloud Costs
Implementing CI/CD in cloud environments accelerates software delivery by automating and streamlining the release process, enabling faster feature delivery and bug fixes.
An e-commerce company has recently faced a breach where an employee was able to access customer payment details. They want to implement a system where each employee only has access to the information necessary for their specific job. What would be the best approach for this company?
- Biometric Authentication
- Firewall
- Intrusion Prevention System
- Principle of Least Privilege
Implementing the Principle of Least Privilege ensures that each employee has access only to the information necessary for their specific job, reducing the risk of breaches.
