A business is looking to deploy a web application quickly without managing the operating system or application runtime. Which service model should they choose?
Answer:
PaaS.
PaaS provides a platform for developers to deploy and run applications without the overhead of managing the underlying infrastructure like operating systems, virtual machines, and network hardware.
882
What is the main purpose of containerization in cloud-native applications?
Answer:
To encapsulate an application and its dependencies into a single, portable unit.
Containerization (e.g., Docker) packages an application and all its dependencies (libraries, frameworks, and configurations) into an isolated unit called a container, making applications portable and consistent across different environments, thus simplifying deployment and scaling.
883
A startup needs to quickly deploy and scale a new customer relationship management (CRM) application without investing in hardware or software licenses. Which cloud service model is most appropriate?
Answer:
SaaS.
For a CRM application, SaaS is ideal as it provides a complete, ready-to-use software solution accessible over the internet, requiring no infrastructure management or software installation by the user.
884
What is a 'Content Delivery Network' (CDN) in the context of cloud services?
Answer:
A geographically distributed network of proxy servers and their data centers.
A CDN is a geographically distributed network of proxy servers and their data centers, providing high availability and performance by distributing service spatially relative to end-users. It delivers web content and static assets by caching them closer to the user.
885
Which of the following best describes 'cloud bursting'?
Answer:
An application runs in a private cloud or data center and then 'bursts' into a public cloud when demand for computing capacity spikes.
Cloud bursting is a hybrid cloud deployment model where an application typically runs in a private cloud or data center and then 'bursts' into a public cloud when demand for computing capacity spikes, leveraging rapid elasticity.
886
In a Public Cloud deployment model, who is responsible for managing and maintaining the underlying infrastructure?
Answer:
The cloud provider.
In a public cloud, the cloud provider owns and operates the infrastructure, and users access services over the internet, relieving users of the burden of infrastructure management.
887
What is 'DevOps' in the context of cloud computing?
Answer:
A methodology that combines software development (Dev) with IT operations (Ops) to shorten the systems development life cycle and provide continuous delivery with high software quality.
DevOps is a set of practices that combines software development and IT operations. It aims to shorten the systems development life cycle and provide continuous delivery with high software quality, often leveraging cloud tools for automation and scalability.
888
Which concept allows cloud resources to be defined and managed as code, promoting automation and consistency?
Answer:
Infrastructure as Code (IaC).
Infrastructure as Code (IaC) is the managing and provisioning of computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. This enables automation, version control, and consistent deployment of cloud resources.
889
A company requires a cloud infrastructure that combines its on-premise data center with public cloud services. Which deployment model would be most suitable?
Answer:
Hybrid Cloud.
A hybrid cloud combines two or more distinct cloud infrastructures (private, community, or public) that are bound together by standardized or proprietary technology, enabling data and application portability.
890
Which characteristic of cloud computing allows users to scale resources up or down rapidly and elastically?
Answer:
Rapid elasticity.
Rapid elasticity enables capabilities to be elastically provisioned and released to scale rapidly outward and inward commensurate with demand, providing flexibility in resource utilization.
