IBM A1000-106 Practice Exam 2025: Latest Questions

A team is designing a highly available web application on IBM Cloud. They want to distribute incoming HTTP traffic across multiple application instances and perform health checks so unhealthy instances stop receiving traffic. Which IBM Cloud service best fits this requirement?

A company must enforce the principle of least privilege for administrators managing IBM Cloud resources across multiple teams. Which approach is the best practice?

A developer needs a way to manage and provision IBM Cloud infrastructure in a repeatable manner across dev, test, and prod environments. Which approach is most appropriate?

Operations reports that they need a centralized view of application and infrastructure logs to quickly troubleshoot issues across multiple IBM Cloud services. What is the most suitable capability to implement?

A financial services application must encrypt data at rest and ensure encryption keys are managed and rotated under strict access control. Which IBM Cloud approach best meets this requirement?

A microservices application experiences intermittent failures when one downstream service becomes slow. The team wants to prevent cascading failures and allow the system to degrade gracefully. Which design pattern should be implemented?

A team wants to deploy a containerized application with a safe rollout strategy that allows quick rollback if errors increase after release. Which deployment approach best supports this?

After a recent change, API latency increased sharply. The team needs to identify whether the bottleneck is in the API service, a database call, or an external dependency. Which observability capability is most directly suited to pinpoint where time is spent across services?

A regulated workload requires that all administrative actions and access policy changes in an IBM Cloud account are recorded and retained for audit investigations. Which solution best addresses this requirement?

A company needs a hybrid integration where an on-premises system triggers processing in IBM Cloud without exposing inbound ports to the internet. Messages must be delivered reliably even if the cloud application is temporarily unavailable. Which architecture is most appropriate?

A team is designing a highly available web application on IBM Cloud. They want incoming traffic to automatically route only to healthy application instances across multiple zones. Which IBM Cloud capability best meets this requirement?

A financial services company must ensure sensitive data is encrypted with customer-controlled keys and must be able to rotate and revoke keys when required. Which IBM Cloud service should they use to manage the encryption keys?

An operations engineer wants a single place to view IBM Cloud platform events (such as resource lifecycle changes) for auditing and investigations. Which service is the best fit?

A team needs to deploy the same IBM Cloud infrastructure (VPC network, subnets, and compute instances) consistently across dev, test, and prod with repeatable changes and version control. Which approach is recommended?

A company wants developers to push code to a repository and automatically run tests, build a container image, and deploy it to IBM Cloud with minimal manual steps. Which solution best addresses this CI/CD requirement?

An application team is troubleshooting intermittent failures in a microservices application. They can see HTTP 500 errors but cannot determine which downstream service causes the latency spikes. What is the most effective monitoring approach to identify the bottleneck?

A security team wants to ensure IBM Cloud resources cannot be created outside approved regions and that object storage buckets must not be publicly accessible. What is the best way to enforce these rules at scale?

A workload experiences unpredictable traffic bursts. The team wants the platform to automatically add capacity during spikes and reduce capacity when demand drops, while maintaining application responsiveness. Which design choice best supports this goal?

A company needs to connect an on-premises data center to IBM Cloud VPC with consistent network performance and lower exposure to the public internet. They also require private access to cloud services where possible. Which connectivity approach is most appropriate?

A regulated organization must demonstrate separation of duties: developers can deploy applications, but only security administrators can manage IAM policies and key management settings. What is the best way to implement this requirement in IBM Cloud?

A team is building a public-facing API on IBM Cloud. They need to protect against common web attacks (e.g., SQL injection patterns and malicious bots) and want the controls to be applied at the edge before requests reach the application. Which solution best fits this requirement?

A company runs microservices on IBM Cloud Kubernetes Service (IKS). They want to enforce that only approved images can run in production and that deployments are blocked if critical vulnerabilities are found. Which approach is most appropriate?

An application is deployed across two regions for high availability. Users intermittently report being routed to the wrong region after a failover test. The team suspects DNS caching is causing delays in routing changes. What is the best practice to reduce this problem?

A workload requires a secure, private connection from IBM Cloud to an on-premises data center with predictable performance. The solution must avoid traversing the public internet and should support routing multiple VLANs/subnets. Which option best meets these requirements?

After migrating to IBM Cloud, a team notices their Kubernetes cluster experiences periodic latency spikes. Monitoring shows high CPU throttling on several pods, but node CPU is not fully utilized. Which action is most likely to address the issue?
