IBM A1000-002 - IBM Assessment: Cloud Computing Architecture V1 Practice Exam 2025: Latest Questions

A startup wants to quickly deploy a web application without managing servers. They need automatic scaling and pay-per-use based on requests. Which cloud compute approach best fits these requirements?

A project team is debating cloud service models. Which option is the best example of Platform as a Service (PaaS)?

A healthcare organization must ensure only authorized services can call an internal patient-record API, and each service should have the minimum required permissions. Which design principle best addresses this requirement?

An application stores user-uploaded images and must scale to millions of files. The images are accessed by many instances of the web tier. Which storage type is most appropriate?

A retailer is designing a new customer-facing application for high availability across multiple zones. What is the most appropriate approach to reduce the impact of a zone outage?

A team is modernizing an order-processing system. They want to decouple the web front end from the back-end processing so that order submissions are not lost during traffic spikes. Which design best meets this goal?

An operations team notices that a stateless API deployed on multiple instances becomes unreachable intermittently. Metrics show that some instances are healthy but are not receiving any traffic. Which configuration issue is the most likely cause?

A company is migrating a legacy application to the cloud with minimal code changes. The application depends on an on-premises database that will remain on-prem for six months. What is the best approach to securely connect the cloud-hosted application to the on-premises database during this period?

A financial services company must meet strict regulatory requirements for key management. They need the ability to control encryption keys, rotate them, and ensure only approved workloads can use them. Which approach best satisfies these requirements?

Which statement best describes the shared responsibility model in cloud computing?

A team is deploying a stateless web application to the cloud. To follow best practice for high availability and elasticity, which design choice is most appropriate?

A company wants to reduce risk during cloud adoption by moving an existing application with minimal code changes, while keeping the same architecture initially. Which migration approach does this describe?

A financial services company must restrict administrative access to production cloud resources. Which control best enforces least privilege and reduces the chance of credential misuse?

A microservices application experiences intermittent failures when one downstream service becomes slow. The team wants to prevent cascading failures and improve resilience. Which pattern should be implemented?

An application must store large unstructured files (images and videos) and serve them efficiently to users worldwide. Which cloud storage choice is most appropriate?

A team uses containers in production. They need automated scheduling, self-healing, rolling updates, and service discovery. Which approach best meets these requirements?

After migrating a three-tier application to the cloud, performance is inconsistent. Metrics show the database CPU is low, but storage I/O wait is high during peak loads. What is the most likely improvement?

A retailer must meet strict data residency requirements: customer PII must remain in a specific country, but the company also wants low-latency global access for non-sensitive content. Which architecture best satisfies both needs?

A company plans to migrate many applications and wants consistent network segmentation and security controls across environments, with the ability to audit and reproduce changes. Which approach is most appropriate?

A development team wants to deploy a stateless web API that experiences unpredictable traffic spikes. They want the platform to automatically scale and they do not want to manage servers. Which cloud service model best fits this requirement?

A retailer is designing a multi-tier cloud application. The database must not be directly reachable from the public internet, but the web tier must be publicly accessible. Which network design best practice addresses this requirement?

An organization needs to centralize authentication for multiple cloud-hosted applications and enforce least privilege using roles. Which approach best meets this requirement?

A company is migrating a customer-facing application to the cloud. A key requirement is resilience to a single data center failure with minimal service interruption. Which design is MOST appropriate?

During a pilot migration, an application intermittently fails to connect to a managed database service in the cloud. The database is in a private subnet, and the application is in a public subnet. Security group rules allow the database port from the application security group. What is the MOST likely missing configuration?
