IBM A1000-086 Intermediate Practice Exam: Medium Difficulty 2025

A development team is deploying a multi-tier web application on IBM Cloud that requires compute instances in multiple availability zones for high availability. They need to ensure that all instances can communicate privately while remaining isolated from the public internet. Which combination of IBM Cloud services should they implement?

An enterprise application deployed on IBM Cloud Object Storage needs to implement lifecycle management to optimize costs. Objects should be moved to cold storage after 90 days of inactivity and deleted after 2 years. What is the most appropriate approach?

A company is migrating a legacy application to IBM Cloud and needs to understand resource consumption and allocation across multiple departments. The finance team requires detailed cost breakdown by project and environment (dev, test, prod). What strategy should the cloud architect implement?

A microservices application running on IBM Cloud Kubernetes Service experiences intermittent connection timeouts to a backend database during peak traffic hours. The database instance has sufficient capacity, and CPU/memory metrics show normal usage. What should be investigated first to resolve this issue?

A development team is deploying a Cloud Foundry application on IBM Cloud that requires different configurations for development and production environments. The application uses external APIs with different endpoints and credentials for each environment. What is the best practice for managing these configurations?

An organization needs to implement identity and access management for their IBM Cloud resources where different teams require varying levels of access. The security team wants to ensure least privilege access while allowing team leads to manage permissions for their respective teams. What IAM strategy should be implemented?

A company is building a data analytics pipeline on IBM Cloud that ingests streaming data, processes it, and stores results for visualization. The solution needs to handle variable data volumes and be cost-effective during low-activity periods. Which architectural pattern best fits these requirements?

A containerized application on IBM Cloud Kubernetes Service needs to access sensitive database credentials. The security team mandates that credentials must be encrypted at rest, rotated regularly, and never exposed in container images or environment variables. What solution addresses these requirements?

A retail company is deploying an e-commerce application on IBM Cloud that must handle traffic spikes during sales events while maintaining performance. The application consists of stateless web servers and a managed database. What deployment strategy ensures both scalability and high availability?

A development team is experiencing issues with an application deployed on IBM Cloud. They need to implement comprehensive monitoring to track application performance, resource utilization, and user experience. The solution should provide alerting capabilities when SLA thresholds are breached. What approach should they implement?
