A startup is deploying a simple web application on IBM Cloud and wants the fastest way to expose it publicly with HTTPS and a custom domain while minimizing operational overhead. Which approach best fits this requirement?

A team must ensure that a regulated dataset stored in IBM Cloud is encrypted with customer-controlled keys and that key usage can be audited. Which solution best meets this requirement?

An operations engineer wants to quickly troubleshoot intermittent application failures. What is the most effective first step to improve diagnosability without changing application code?

A financial services company is building a multi-team IBM Cloud environment and wants to reduce risk by preventing developers from creating internet-facing resources in production accounts. Which design is most appropriate?

A team is integrating an on-premises system with IBM Cloud services. The requirement is to keep traffic off the public internet and use private addressing. Which solution is most appropriate?

A platform team wants to standardize deployments across environments and ensure the same infrastructure configuration is reproducible. Which approach best supports this goal?

A team notices that an application hosted on IBM Cloud occasionally slows down during traffic spikes. They want an approach that balances performance and cost by scaling only when needed. What should they implement?

A company must demonstrate that administrative actions on IBM Cloud resources can be traced to individual users for audit purposes. Which practice best satisfies this requirement?

A microservices application runs on IBM Cloud and uses a managed database. The team needs a deployment strategy that minimizes downtime and allows quick rollback if a new release increases error rates. Which strategy is most appropriate?

A security team wants to reduce the blast radius of a compromised workload and limit outbound data exfiltration from a VPC-based application. Which control is most directly applicable?

A developer is new to IBM Cloud and wants to run a containerized web application without managing worker nodes or Kubernetes upgrades. Which IBM Cloud service best fits this requirement?

An operations team needs to rotate application credentials automatically and avoid embedding secrets in container images. Which IBM Cloud capability is the best fit?

A team has two VPCs in the same region: one for shared services (logging, monitoring) and one for application workloads. They need private, high-throughput connectivity between the VPCs without using the public internet. What should they use?

An application hosted on IBM Cloud has intermittent latency spikes. The team wants to be notified automatically when response time exceeds a threshold. Which approach is most appropriate?

A regulated healthcare workload must ensure that encryption keys are controlled by the customer and that key usage can be audited. Which IBM Cloud service combination best supports this requirement?

A company wants an API layer for multiple microservices. They need centralized authentication, rate limiting, and request logging without changing each service. What is the best solution on IBM Cloud?

A team uses IBM Cloud Object Storage and needs to ensure that accidental deletion of objects can be recovered. Which feature should they enable?

A platform team wants to standardize provisioning of IBM Cloud resources (VPC, subnets, security groups) across multiple environments with repeatability and approval workflows. Which approach best matches this goal?

An enterprise uses IBM Cloud accounts for multiple teams. They must ensure developers can deploy resources but cannot change IAM policies or billing settings. What is the best practice to meet this requirement?

A production workload is scaling up and down. The team wants to reduce cost while maintaining performance, and they need to identify which services and resource groups are driving spend. Which combination best supports this objective?

A team wants to give developers access to deploy and restart apps in a specific IBM Cloud resource group, but they must not be able to create or delete service instances. Which IAM approach best meets this requirement?

An application running on IBM Cloud Kubernetes Service (IKS) needs to securely access an IBM Cloud service (for example, Object Storage) without embedding long-lived API keys in container images. What is the recommended approach?

A solution requires private connectivity from an on-premises data center to IBM Cloud with consistent network performance and without traversing the public internet. Which connectivity option is most appropriate?

A microservices application has bursts of traffic and must scale automatically based on request volume. The team also wants to avoid managing servers. Which IBM Cloud compute model best fits these requirements?

A deployment pipeline builds a container image and deploys it to a Kubernetes cluster. The security team requires that only signed images from the approved registry can be deployed. Which control best addresses this requirement?

An application deployed across multiple availability zones is experiencing intermittent latency spikes. The operations team needs a method to correlate a user request across multiple microservices to identify the slow component. What should they implement?
