Free CompTIA Cloud+ Cloud Service Deployment Questions and Answers — Questions and Answers
Question 1: An e-commerce company experiences massive, predictable traffic surges during holiday sales. They maintain an on-premises data center for normal operations but want to leverage the public cloud to handle the peak load without permanently provisioning expensive hardware. Which cloud deployment strategy should they use?
- Cloud bursting (Correct answer)
- Cloud balancing
- Vertical scaling
- Multi-cloud
Correct answer: Cloud bursting
Cloud bursting is a hybrid cloud deployment model where an application runs in a private cloud or on-premises data center and 'bursts' into a public cloud when the demand for computing capacity spikes. This is the perfect model for handling seasonal or predictable traffic surges, as it allows the company to pay for extra resources only when needed.
Question 2: A cloud engineer needs to define and provision a complex cloud environment consisting of virtual networks, subnets, virtual machines, and load balancers using version-controlled configuration files. The goal is to create a consistent, repeatable, and automated deployment process. Which of the following technologies should be used?
- A containerization platform
- A serverless computing service
- An Infrastructure as Code (IaC) tool (Correct answer)
- A configuration management database (CMDB)
Correct answer: An Infrastructure as Code (IaC) tool
Infrastructure as Code (IaC) is the practice of managing and provisioning computing infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. Tools like Terraform, AWS CloudFormation, and Azure Resource Manager allow engineers to codify their infrastructure, which enables automation, version control, and consistency across deployments.
Question 3: A development team wants to release a new feature with minimal risk. They plan to deploy the new version of their application to a small subset of live users (e.g., 5%) while the majority of users continue to use the current stable version. They will monitor the new version's performance and error rates before gradually routing more traffic to it. Which deployment strategy are they implementing?
- Blue-green deployment
- Rolling deployment
- A/B testing
- Canary deployment (Correct answer)
Correct answer: Canary deployment
A canary deployment is a strategy where a new version of software is rolled out to a small, controlled group of users to test its performance and stability in a live environment before a full release. This method minimizes the potential impact of any bugs or issues by limiting the 'blast radius' to a small percentage of the user base.
Question 4: Which of the following BEST describes the role of orchestration in a cloud deployment context?
- The process of running a single, repetitive task, such as starting a virtual machine, without human intervention.
- The coordination of multiple automated tasks into a coherent, end-to-end workflow to deploy a complex application. (Correct answer)
- The manual configuration of network devices and servers according to a deployment plan.
- The process of monitoring application performance and resource utilization after deployment.
Correct answer: The coordination of multiple automated tasks into a coherent, end-to-end workflow to deploy a complex application.
While automation focuses on individual tasks, orchestration involves arranging and coordinating multiple automated tasks into a complete workflow. For example, deploying a multi-tier application involves orchestrating the provisioning of servers, configuring networks, installing software, and connecting to a database in the correct sequence.
Question 5: A cloud administrator is implementing a CI/CD pipeline. In which stage of the pipeline is the application's source code compiled and packaged into a deployable artifact, such as a container image or a binary file?
- Test
- Deploy
- Build (Correct answer)
- Source
Correct answer: Build
In a CI/CD pipeline, the 'Build' stage is responsible for taking the source code from version control, compiling it, and packaging it into a runnable artifact. This stage ensures the code is syntactically correct and can be prepared for the subsequent testing and deployment stages.
Question 6: A company wants to achieve zero-downtime deployments. Their strategy involves setting up a completely identical, second production environment. Once the new version of the application is deployed and fully tested on this second environment, a load balancer instantly switches all user traffic from the old environment to the new one. What is this deployment strategy called?
- Canary release
- Blue-green deployment (Correct answer)
- Rolling update
- Shadow deployment
Correct answer: Blue-green deployment
Blue-green deployment is a release strategy that reduces downtime and risk by running two identical production environments, referred to as 'Blue' and 'Green'. At any time, only one environment is live. The new version is deployed to the inactive environment, and once it passes all tests, traffic is switched over instantly, making the new environment live. The old environment can be kept on standby for a quick rollback if needed.
