IBM A1000-123 Practice Exam 2025: Latest Questions

A team is new to IBM Cloud and wants a quick way to deploy a simple web app without managing servers. Which IBM Cloud approach best fits this requirement?

A developer needs to store application files (images and documents) in a highly durable, scalable storage service accessible over HTTP. Which IBM Cloud service should they choose?

An organization must ensure that only users from its corporate identity provider can access IBM Cloud resources, and access should be centrally managed. What is the recommended approach?

A workload is experiencing slow response times. The team wants to see CPU, memory, and network metrics for their IBM Cloud resources to identify bottlenecks. Which capability should they use first?

A company is deploying a multi-tier application. The database must not be reachable from the public internet, but the web tier must be public. Which design best meets this requirement on IBM Cloud?

An application is deployed on Kubernetes. The team wants a repeatable way to provision the cluster, networking, and managed database across environments (dev/test/prod) with minimal drift. What is the best approach?

A microservices application needs to rotate API keys regularly and avoid embedding secrets in container images or source code. Which IBM Cloud practice best addresses this?

A team observes intermittent errors in a containerized service. They need to correlate application logs with spikes in latency to determine whether failures are due to timeouts or downstream dependencies. What should they implement?

A regulated workload requires customer-managed encryption keys (BYOK) and proof that key usage can be audited. Which architecture best meets this requirement on IBM Cloud?

A production service must handle unpredictable traffic bursts while keeping costs controlled. The team wants the platform to automatically add or remove capacity based on demand and avoid over-provisioning. Which solution is most appropriate?

A team is deciding how to isolate workloads that must be billed to different business units while still allowing centralized governance. Which IBM Cloud approach best supports this requirement?

A developer wants to quickly deploy a stateless web API without managing servers and with automatic scaling based on incoming requests. Which IBM Cloud compute option best fits?

A security engineer needs to ensure that application users can access an IBM Cloud-hosted app using their corporate identity provider and that access is centrally managed. What is the best solution?

A workload running on Virtual Servers for VPC needs to access an IBM Cloud service (for example, Object Storage) without exposing traffic to the public internet. Which design is most appropriate?

An operations team wants near real-time visibility into application errors and the ability to search across logs from multiple microservices. Which IBM Cloud capability best meets this need?

A regulated workload requires that secrets (database passwords, API credentials) are never stored in source code or CI/CD variables in plaintext. What is the recommended approach on IBM Cloud?

A team is troubleshooting intermittent connectivity to a VSI. The security group allows inbound SSH (22) from the corporate IP range, but users still cannot connect. Which is the MOST likely additional IBM Cloud VPC configuration issue?

A company must prove that administrative actions taken in the IBM Cloud account can be audited for compliance. Which capability should be enabled and reviewed regularly?

A multi-region application uses Object Storage for static assets. Users in one region report high latency when loading assets. Which architecture change is the BEST first step to reduce latency while keeping the storage layer simple?

An enterprise requires customer-managed encryption keys, separation of duties for key administrators vs. application operators, and the ability to revoke access to encrypted data quickly. Which solution best meets these requirements on IBM Cloud?

A new team member needs access to manage only IBM Cloud Object Storage buckets within a single resource group, without being able to create or delete other IBM Cloud services. What is the BEST approach?

An application requires a database credential for runtime access. The security team mandates that credentials must not be stored in source code or container images, and access should be auditable and centrally managed. Which solution BEST meets these requirements on IBM Cloud?

A team deployed a containerized microservice to production. After release, response times intermittently spike and users report timeouts, but CPU usage remains low. Which monitoring approach is MOST likely to help identify the root cause quickly?

A company wants to isolate development and production workloads while still using a single IBM Cloud account for consolidated billing. Which is the MOST appropriate way to organize resources?

A regulated workload must ensure that only private network paths are used between an application and its backing services, and that internet egress is minimized. Which architecture choice BEST supports this requirement on IBM Cloud?
