IBM A1000-004 - Assessment: Cloud Computing and Platform Services v1 Practice Exam 2025: Latest Questions

An application experiences unpredictable spikes in usage during marketing campaigns. The team wants to avoid overprovisioning while still meeting demand. Which cloud characteristic best addresses this need?

A developer needs to store unstructured data such as images and log archives in a highly durable, HTTP-accessible repository. Which IBM Cloud storage option best fits this requirement?

A security team wants to ensure no public IP addresses are exposed for a set of backend services. They also want controlled inbound/outbound network rules. Which approach best meets this requirement?

Operations notices that the same configuration changes are repeatedly applied manually to multiple environments, causing inconsistencies. What is the best practice to reduce errors and ensure repeatability?

A team wants to build a microservices application where services communicate asynchronously to handle bursts of events without dropping messages. Which design choice is most appropriate?

A company wants to securely store API keys and rotate them without embedding secrets in application code or container images. Which IBM Cloud capability is the best fit?

A team deployed an application to a managed Kubernetes cluster. Pods are running, but users report intermittent 503 errors. Metrics show some pods become unresponsive under load. What is the most appropriate Kubernetes configuration to improve reliability?

A startup is building a new web app and wants to minimize operational overhead for runtime patching and scaling while focusing on code. Which cloud service model best aligns with this goal?

A regulated enterprise requires workload isolation at the hardware level and must avoid sharing physical hosts with other tenants. Which deployment approach best meets this requirement on IBM Cloud?

An organization wants to detect and respond to policy violations across multiple IBM Cloud accounts (for example, publicly exposed resources or noncompliant configurations). They need continuous visibility and governance rather than one-time checks. What is the best approach?

A small team wants to deploy a simple stateless web API on IBM Cloud without managing servers, and they want the platform to automatically scale based on incoming requests. Which approach best fits this requirement?

A developer needs an IBM Cloud service that stores application configuration and credentials (such as API keys) securely and allows controlled access without hard-coding secrets in code or container images. Which service should be used?

A team is deciding between public cloud, private cloud, and hybrid cloud. They must keep certain sensitive data on-premises due to regulatory requirements while running customer-facing applications in the cloud. Which deployment model best matches this requirement?

A company uses multiple IBM Cloud services and needs to ensure all user and service access is centrally controlled with least-privilege permissions. Which IBM Cloud capability should they primarily use?

A microservices application on IBM Cloud experiences occasional slowdowns. The operations team wants to identify which service is causing latency across distributed requests. What is the most effective observability approach?

A solution architect is designing an application that must remain available during a zone outage in an IBM Cloud region. Which design is the best practice for high availability?

A team is building an event-driven workflow where uploading a file should trigger processing and then notify another service when completed. Which architectural pattern best fits this requirement?

A company wants to automate provisioning of IBM Cloud infrastructure so environments are consistent and repeatable across dev, test, and prod. Which practice is most appropriate?

A financial services application must encrypt sensitive data and control encryption keys such that the organization can manage and rotate keys while enforcing strict access controls. Which approach best meets this requirement on IBM Cloud?

A multi-tier application in IBM Cloud VPC cannot connect from the application subnet to a managed database service using a private endpoint. DNS resolves to a public IP, and security groups appear correct. What is the MOST likely root cause?

A development team wants to deploy a containerized web API to IBM Cloud. They do not want to manage worker nodes, scaling, or cluster upgrades, but they still need Kubernetes-compatible deployment primitives (Deployments, Services, Ingress). Which IBM Cloud offering best fits this requirement?

A company is moving an internal application to the cloud and must ensure that only private network traffic is used between the application running in IBM Cloud and IBM Cloud-managed services (for example, databases) to reduce exposure to the public internet. Which design choice best meets this requirement?

A security team needs to audit which user or service performed administrative actions in an IBM Cloud account (for example, creating resources or changing access policies). Which capability should they use to capture and review this activity?

An application has a single API endpoint receiving unpredictable bursts of traffic. The team wants to protect the back-end service from being overwhelmed and also wants to decouple request intake from processing so they can scale workers independently. Which architecture pattern is most appropriate?

A team is troubleshooting intermittent failures when a microservice calls another service. Logs show frequent TCP connection resets and high latency during peak load. The services run in containers and scale up and down frequently. Which change is most likely to improve reliability with minimal application code changes?
