Which of the following models provides tools to support application development, such as development frameworks, databases, and caching systems?
- Function as a Service (FaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Platform as a Service (PaaS) provides a comprehensive environment for application development. It includes development frameworks, databases, and caching systems, allowing developers to build and deploy applications without worrying about managing the infrastructure or the underlying services.
Reserved instances in cloud services primarily help in:
- Enhancing network speed and reliability
- Ensuring data confidentiality
- Reducing infrastructure costs
- Streamlining code deployment
Reserved instances in cloud services help reduce infrastructure costs by allowing users to commit to long-term usage of specific cloud resources, typically at a lower hourly rate compared to on-demand instances. This commitment ensures cost savings.
An e-commerce company is expecting a huge surge in traffic during a sale event. They want to ensure that they have the flexibility to quickly scale up or down their infrastructure resources. Which cloud service model would best fit their needs?
- Function as a Service (FaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
The e-commerce company should opt for Infrastructure as a Service (IaaS). IaaS allows them to scale resources as needed, making it suitable for handling traffic spikes. It provides control over infrastructure.
Which of the following best describes an insider threat in the context of data security?
- A threat from employees
- A threat from external hackers
- A threat from natural disasters
- A threat from viruses
An insider threat in data security refers to threats originating from individuals within the organization, such as employees or contractors. These individuals have access to sensitive data and may misuse it intentionally or unintentionally.
In a scenario where an organization wants to quickly test a new application in a cost-effective manner without concerns for initial infrastructure investments, which cloud model is more appropriate?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
Public Cloud is the best choice for quickly testing new applications with minimal upfront costs. It provides scalable resources and doesn't require organizations to invest heavily in infrastructure. Private clouds are more suited for long-term, controlled environments.
Which cloud model often involves shared resources and benefits from economies of scale?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
Public Clouds are shared environments where resources are pooled, leading to economies of scale. They're accessible to the general public and often cost-effective.
