Practice Quiz: Service Models
1. In the car analogy used in the video to explain and differentiate between the three service models, which of the provided options is an analogy for PaaS?
- Rentinga car
- Leasing a car
- Buying a car
- Hiring a taxi
2. Which is a characteristic of cloud infrastructure as a service model?
- No supporting services provided by laaS
- End users interact directly with the physical infrastructure
- Users can access networking resources on the cloud through virtualization
- Data can only be stored on physical machines in the network
3. Which of these scenarios are good use cases for PaaS?
- Organizations who want to maintain full control over the installation, configuration, and operation of their application infrastructure
- IoT deployment
- Organizations who want to manage the lower-level details of the application environment
- Organizations who want the maintenance of their applications to be done by the service provider
4. Which one of the following is a good use case for SaaS?
- Organizations looking to reduce on-premises IT infrastructure and capital expenditure
- Business-critical applications
- Organizations that have a geographically spread workforce, some of them working in areas with erratic or unreliable internet connections
- Applications that have highly confidential and sensitive data
Practice Quiz: Deployment Models
5. Which of these scenarios are good use cases for Public Cloud? Select two.
- Reducing time-to-market for products and services
- Managing business critical platforms and applications
- Applications with stable capacity and resourcing needs
- Disaster recovery, data protection, and business continuity
6. What do we mean when we say that the Hybrid Cloud is interoperable?
- When there is a spike in demand, a workload running on the private cloud can leverage the additional public cloud capacity
- The public and private cloud services can understand each other’s APIs, configuration, data formats, and forms of authentication and authorization
- Organizations can choose to run their sensitive workloads on a private cloud
- You are no longer locked-in with a specific vendor
7. What is the benefit of using private cloud?
- Common access to all with minimum security
- Ability to better utilize external resources outside organization
- Ability to provision limited resources saving costs
- Leverage usage of systems directly controlled by organization
Module 2 Graded Quiz: Cloud Computing Models
8. In which cloud service model does the service provider manage the application data along with the infrastructure and platform resources?
- SaaS
- PaaS
- CaaS
- IaaS
9. In which laas cloud environment can the customers deploy their middleware and install applications?
- IoT
- Blockchain
- Virtual Machines
- AI
10. What is one of the concerns in cloud infrastructure configuration and management?
- Solving complex problems involving millions of variables and calculations
- Scaling infrastructure up and down as demand fluctuates
- Business continuity and disaster recovery
- Dependency on a third party for workload availability and performance
11. What is the responsibility of a user in the PaaS model?
- Business process management systems
- Application code and its maintenance
- Workload management
- Database management systems
12. Which capability in the PaaS model eliminates the need for the integration of disparate components?
- Runtime environment
- Rapid deployment mechanisms
- APIs for services
- Business analytics services
13. Which is a characteristic of the SaaS model?
- Users can see only their own application
- Infrastructure and code are maintained by the users
- Applications reside on a remote cloud network
- Services are free for the users on the SaaS cloud
14. What s the users’ role in a public cloud?
- Users own the storage their data consumes
- Users maintain the platform that runs their application
- Users can manage the operations of the servers
- Users don’t own the servers their applications run on
15. What is a feature of a private cloud?
- Application portability
- Uncontrolled access
- Use of external computing resources
- Limited security
16. If an organization needs to run a highly sensitive and mission-critical application with unpredictable performance and capacity requirements, which of the following models would best meet its requirements?
- On-premise Data Centers
- Hybrid Cloud
- Private Cloud
- Public Cloud
17. What do you mean by “cloud bursting”?
- You can spin-up environments using pay-as-you-go in the public cloud
- You can incrementally modernize your core business systems.
- You can leverage public cloud instances for a period of time but return to the private cloud when the surge is met
- You can move applications and data between on-premises and cloud systems.
