1In cloud computing, which deployment model gives a single organization exclusive, dedicated infrastructure that may be hosted on-premises or by a third party?
A.Public cloud
B.Hybrid cloud
C.Private cloud
D.Community cloud
Explanation: A private cloud provisions cloud resources for the exclusive use of one organization, whether self-hosted or vendor-managed, giving greater control and isolation. This contrasts with shared public infrastructure.
2Which cloud service model delivers ready-to-use applications over the internet so users do not manage the underlying servers, runtime, or code, such as email or CRM tools?
A.IaaS (Infrastructure as a Service)
B.PaaS (Platform as a Service)
C.FaaS (Function as a Service)
D.SaaS (Software as a Service)
Explanation: Software as a Service (SaaS) delivers complete, hosted applications that users consume through a browser while the provider manages everything from hardware to the application itself. Salesforce and Gmail are classic examples.
3According to the Twelve-Factor App methodology, where should configuration that varies between deploys (such as database credentials) be stored?
A.In environment variables
B.In a config.json file committed to the repository
C.Hardcoded in the application source
D.In the container image layers
Explanation: The Twelve-Factor App methodology says config that varies between environments must be stored in the environment (typically environment variables), keeping it strictly separated from code so the same build can run anywhere. This prevents secrets from leaking into version control.
4What is the primary goal of a CI/CD pipeline in modern software delivery?
A.To manually review every code change before merging
B.To automate building, testing, and deploying code changes
C.To replace version control with a single shared folder
D.To eliminate the need for automated tests
Explanation: Continuous Integration/Continuous Delivery (CI/CD) automates the build, test, and deployment stages so that code changes flow to users quickly and reliably with minimal manual intervention. Continuous Integration merges and tests changes frequently; Continuous Delivery/Deployment automates release.
5Which characteristic best describes DevOps as a practice?
A.A programming language for cloud automation
B.A type of database used for microservices
C.A culture that unifies development and operations to deliver software faster and more reliably
D.A proprietary IBM container runtime
Explanation: DevOps is a cultural and operational practice that breaks down silos between development and operations teams, emphasizing automation, continuous feedback, and shared responsibility to ship software faster and more reliably. It is enabled by tools like CI/CD pipelines and infrastructure as code, but it is fundamentally a culture.
6Which cloud computing benefit is best described by the ability to automatically add or remove resources to match demand?
A.Vendor lock-in
B.Statelessness
C.Latency
D.Elasticity
Explanation: Elasticity is the cloud's ability to scale resources up or down automatically in response to changing workload demand, so you provision capacity dynamically rather than for peak load. This underpins cost efficiency and resilience in cloud-native applications.
7In the IBM Cloud and cloud-native context, what does 'serverless computing' (FaaS) mean for the developer?
A.The developer writes functions that run on demand while the provider manages server provisioning and scaling
B.The application runs without any servers at all
C.The application must run on a dedicated physical server
D.Servers are replaced by client-side JavaScript only
Explanation: Serverless computing (Function as a Service) lets developers deploy individual functions that execute in response to events, while the cloud provider transparently handles provisioning, scaling, and capacity. Servers still exist, but the developer never manages them and typically pays only for execution time.
8Which statement correctly distinguishes scaling 'out' (horizontal) from scaling 'up' (vertical)?
A.Scaling out adds more CPU to one server; scaling up adds more servers
B.Scaling out adds more instances; scaling up adds more power to an existing instance
C.Both terms mean the same thing
D.Scaling up is only possible in a private cloud
Explanation: Horizontal scaling (scaling out) adds more instances or nodes to share the load, while vertical scaling (scaling up) increases the resources such as CPU or RAM of a single instance. Cloud-native apps favor horizontal scaling because stateless instances can be added or removed elastically.
9What is the main purpose of a microservices architecture compared to a monolithic application?
A.To force all code into a single deployable unit
B.To eliminate the need for any database
C.To decompose an application into small, independently deployable services that communicate over a network
D.To run the entire app exclusively in the browser
Explanation: Microservices break an application into small, loosely coupled services that each own a specific business capability and can be developed, deployed, and scaled independently, usually communicating via REST APIs or messaging. This contrasts with a monolith where all functionality is bundled into one deployable unit.
10Which IBM Cloud platform abstraction lets developers push source code and have the platform build, deploy, and run it without managing servers or Dockerfiles, following a Platform-as-a-Service model?
A.IBM Cloud Object Storage
B.IBM Watson Studio
C.IBM Db2
D.Cloud Foundry / IBM Code Engine
Explanation: Cloud Foundry and IBM Code Engine are PaaS-style platforms where developers push application source or containers and the platform handles building, deploying, scaling, and running them. In the IBM Full Stack program, learners deploy apps to these platforms using buildpacks and serverless runtimes.
