IBM Assessment: Platform Associate Intermediate Practice Exam: Medium Difficulty 2025

An organization is deploying an IBM platform solution that requires high availability across multiple data centers. The architecture must ensure that if one data center fails, services continue without manual intervention. Which architectural pattern should be implemented to meet these requirements?

During platform deployment, you need to configure secure communication between platform components distributed across three different network zones: DMZ, application tier, and database tier. What is the BEST approach to implement network segmentation while maintaining required component communication?

A platform administrator notices that certain application services are consuming excessive memory, causing performance degradation during peak usage hours. The monitoring dashboard shows memory utilization reaching 95% during these periods. What combination of actions should be taken to address this issue?

Your IBM platform deployment uses a microservices architecture with service discovery and load balancing. After a recent configuration change, some services intermittently fail to connect to dependent services. What should be your systematic troubleshooting approach?

An organization needs to implement a disaster recovery strategy for their IBM platform with an RTO (Recovery Time Objective) of 2 hours and RPO (Recovery Point Objective) of 15 minutes. Which combination of backup and replication strategies would best meet these requirements?

During a platform configuration update, you need to modify security policies that affect multiple interconnected components. What is the recommended approach to minimize service disruption while ensuring configuration consistency?

A platform administrator needs to implement user access controls that support both internal employees using LDAP authentication and external partners using federated identity. The solution must provide role-based access control (RBAC) and audit logging. What integration approach should be used?

After deploying a platform update, application response times have increased by 40%. System metrics show CPU and memory utilization are normal, but database query logs show increased execution times. What is the most effective troubleshooting sequence?

An enterprise is designing a multi-tenant IBM platform architecture where tenant data must be isolated for compliance reasons. Performance requirements specify that the solution must support 500 concurrent tenants with varying workload patterns. Which architectural approach best balances isolation, performance, and resource efficiency?

Your platform monitoring system alerts that SSL certificate expiration is approaching for multiple services in 30 days. The environment includes load balancers, application servers, and API gateways all using certificates. What is the most efficient approach to handle certificate renewal with minimal service disruption?
