A development team wants a quick way to manage identities for IBM Cloud services without creating separate usernames for every service. Which IBM Cloud capability addresses this need?

A company wants to enforce that only approved administrators can create resources in production, while developers can deploy to a separate development account. What is the recommended approach in IBM Cloud?

A security analyst needs to determine who changed an IAM policy for a critical resource. Which service should they use to review these events?

An application running on IBM Cloud needs to access a database without embedding user credentials in code. The team wants credentials to be rotated and centrally managed. What is the best approach?

A team is migrating a stateless web API to IBM Cloud. They require horizontal scaling and want to minimize operational overhead for patching the runtime. Which compute choice best fits?

An operations team needs to investigate intermittent latency spikes in a microservices application. They want correlated infrastructure metrics and application/service metrics to identify the bottleneck. What should they implement first?

A regulated workload must demonstrate that data is encrypted both in transit and at rest. Which combination best satisfies this requirement in IBM Cloud?

A company is designing for business continuity. They need the application to continue operating if an entire availability zone becomes unavailable, without manual intervention. Which architecture best meets this requirement?

A team provisions infrastructure using infrastructure-as-code. A deployment succeeds, but a later update unexpectedly deletes a shared network component used by multiple applications. What is the MOST likely root cause?

A security team requires strict separation of duties: developers can deploy applications but must not be able to modify network security controls or key management settings. Which approach best enforces this in IBM Cloud?

A team wants to quickly provision a logically isolated network on IBM Cloud to host a two-tier app (web and database) with separate subnets. Which IBM Cloud capability best meets this requirement?

A developer reports that an application running on a Virtual Server for VPC cannot reach the public internet. In the VPC, the instance is in a private subnet with no public IP. What is the most likely missing component?

A security team requires that database credentials are not stored in application source code or CI/CD variables. The application runs on IBM Cloud and needs to retrieve secrets at runtime. Which approach best satisfies this requirement?

A company is designing a microservices architecture on IBM Cloud. They want to decouple services and handle bursts of events without losing messages when a downstream service is unavailable. Which design choice best addresses this?

An application team must ensure that only specific IP ranges from a corporate network can access an administrative endpoint of their cloud-hosted service. What is the most appropriate control to implement first?

A team wants to standardize and automate provisioning of IBM Cloud infrastructure across dev, test, and prod, ensuring repeatability and reviewable changes. Which approach best aligns with this goal?

A solution architect must design for high availability within a region for a customer-facing application. Which option best supports resilience against a single zone failure?

A compliance requirement states that all access to sensitive cloud resources must be attributable to an individual or service identity, and shared accounts are prohibited. Which practice best supports this requirement on IBM Cloud?

A regulated workload requires that encryption keys are controlled by the customer, with strict access policies and the ability to rotate keys without re-encrypting all application data manually. Which IBM Cloud design best meets this requirement?

A company plans to connect an on-premises data center to IBM Cloud for a hybrid application. They require predictable network performance, private connectivity (not over the public internet), and the ability to reach multiple VPC workloads. Which solution is the best fit?

A team is new to IBM Cloud and wants a lightweight way to organize resources and assign access so developers can deploy services without getting full account control. Which IBM Cloud construct best fits this need?

An application running on IBM Cloud Virtual Servers for VPC must call a third-party API on the internet. The security team requires that all outbound traffic uses a fixed, allow-listed public IP address. What is the best design to meet this requirement?

A workload on IBM Cloud must ensure that data stored in a managed database is encrypted at rest and that the customer controls the root encryption keys. Which capability most directly meets this requirement?

A microservices application must handle unpredictable traffic spikes. The team wants minimal infrastructure management and automatic scaling based on incoming requests. Which IBM Cloud compute option best aligns with these requirements?

A company needs private, low-latency connectivity between its on-premises data center and IBM Cloud for production workloads. The connection must not traverse the public internet. Which solution is most appropriate?

A team is troubleshooting intermittent access failures to an IBM Cloud object storage bucket from an application. The failures occur only after recent IAM changes. Which is the most likely cause?

An application must store frequently accessed session data with very low latency. Data can be regenerated if lost, but the solution should be highly available. Which IBM Cloud service is the best fit?

A regulated workload must maintain audit evidence of administrative actions in IBM Cloud (for example, who changed IAM policies and when). Which capability should be enabled to meet this requirement?

A company is designing a multi-region active-active architecture on IBM Cloud. They want users to be routed to the nearest healthy region and to fail over automatically when a region becomes unavailable. Which approach best meets these requirements?
