A workload requires a relational database with automated backups and high availability, but the team does not want to manage operating systems, patching, or database installation. Which type of IBM Cloud offering best matches this requirement?

An application deployed on IKS fails to pull its container image from a private registry. Other clusters can pull the same image successfully. Which is the most likely cause?

A globally distributed application must serve content with low latency to users worldwide while protecting the origin from direct internet exposure. Which architecture best achieves this?

A team is new to IBM Cloud and wants a quick way to organize users and resources while keeping billing separate for dev and prod. Which IBM Cloud construct best supports this separation?

An application running in IBM Cloud needs to call IBM Cloud services (for example, Object Storage) without embedding long-lived credentials in code. What is the best practice to authenticate?

A developer needs to deploy a small stateless API quickly and wants IBM Cloud to manage scaling and underlying servers. Which approach best matches this requirement?

A company wants a private connection from its on-premises data center to IBM Cloud to access VPC resources with consistent network performance. Which connectivity option is most appropriate?

A microservices application on IBM Cloud Kubernetes Service (IKS) needs to store database passwords securely and make them available to pods. What is the best practice?

Users report intermittent timeouts when accessing an app hosted on multiple Virtual Server Instances behind an IBM Cloud Load Balancer. The instances are healthy, but some requests still fail. Which load balancer configuration should be checked first?

A team wants to standardize provisioning of VPCs, subnets, and security groups across environments and ensure changes are peer-reviewed and repeatable. Which approach is most appropriate?

A security architect requires that only a specific set of microservices can communicate with a database running inside an IKS cluster. The team wants enforcement at the Kubernetes networking layer. What should be implemented?

A workload in a VPC must access IBM Cloud Object Storage without traversing the public internet. The solution must keep traffic private while maintaining service functionality. What should be used?

A regulated enterprise must ensure application logs cannot be altered after ingestion and must retain them for audits. The team also wants to be able to search logs for troubleshooting. Which design best meets these requirements?

A team is new to IBM Cloud and wants a quick way to organize resources so billing, access control, and resource grouping can be managed cleanly by environment (dev, test, prod). What is the recommended approach?

A developer needs to automate creation of IBM Cloud resources from a CI pipeline and wants the pipeline to have only the minimum required permissions. Which is the best practice?

An application requires multiple subnets in a private network and needs control over IP ranges and routing within IBM Cloud. Which IBM Cloud service best matches this requirement?

A team wants to deploy a containerized microservice without managing worker nodes, and they prefer automatic scaling and reduced operational overhead. Which option best fits?

A solution architect is designing a multi-tier application in IBM Cloud. The web tier must be internet-facing, while the app and database tiers must not be reachable directly from the internet. Which design best meets this requirement in a VPC?

A DevOps team is troubleshooting intermittent 502/503 errors from a service running in a Kubernetes cluster. The service is exposed through an Ingress. What is the most likely first place to check to identify whether the issue is in routing vs. application health?

A team needs to store application configuration values and rotate sensitive secrets (like API tokens) without embedding them in container images. What is the best approach on IBM Cloud?

A team is choosing storage for a new workload. They need storage that can be accessed by multiple virtual server instances and supports shared file semantics (directories/files). Which option best fits?

A regulated workload requires that administrators cannot read application secrets, but the application must retrieve them at runtime. The team also needs auditing of secret access. Which design best satisfies this requirement?

A company is migrating a stateful application to Kubernetes on IBM Cloud and requires persistent storage that survives pod rescheduling across nodes. They also want deployments to be repeatable across environments. Which approach is most appropriate?

A development team wants to experiment with IBM Cloud services quickly but must avoid creating long-lived credentials. Which approach best aligns with this requirement?

A team wants to decouple an application so that multiple services can consume the same events without the publisher needing to know the consumers. Which design approach best fits this goal on IBM Cloud?

A team needs a way to logically group and track IBM Cloud resources (by environment and cost center) without changing the resources themselves. What should they use?

A web application running on IBM Cloud must store user-uploaded images that are accessed globally, require high durability, and do not need POSIX file semantics. Which storage choice is most appropriate?

A team uses Kubernetes on IBM Cloud and wants to reduce operational overhead by ensuring the cluster can automatically replace unhealthy worker nodes. Which capability should they rely on?

An application deployed as containers is experiencing intermittent failures. The operations team needs to correlate a specific user request across multiple microservices. What is the best practice to enable this?

A company wants to run the same containerized application in development, test, and production with environment-specific settings (such as API endpoints) without rebuilding the image. What is the recommended approach?

A security team requires that no public IPs are assigned to application workloads, and all outbound access to the internet must be controlled and logged. What architecture best meets this requirement in IBM Cloud?

A team is troubleshooting an IAM authorization problem. A user can authenticate successfully but receives "not authorized" when attempting to create resources in a specific IBM Cloud service instance. Which is the most likely cause?

A new microservice must expose an API to external consumers. The team needs built-in request throttling, authentication enforcement, and centralized analytics without adding complex custom code. What is the best solution approach?
