IBM Cloud Pak for Integration v2021.2 Administration Advanced Practice Exam: Hard Questions 2025

An enterprise is deploying IBM Cloud Pak for Integration across multiple OpenShift clusters in different geographic regions. They need to implement a disaster recovery strategy where API Connect configurations can be replicated to a secondary cluster with minimal RPO. The primary cluster uses external PostgreSQL and an S3-compatible object storage. What is the most appropriate approach to achieve near-zero RPO for the API management configurations?

A Cloud Pak for Integration administrator notices that App Connect Enterprise integration servers are experiencing intermittent connection timeouts when accessing external REST APIs during peak load periods. The integration flows work correctly during low traffic. CPU and memory utilization are at 45% and 60% respectively. Network policies are properly configured. What is the most likely root cause and resolution?

An organization is implementing a multi-tenant Cloud Pak for Integration environment where different business units require isolated API management capabilities but must share the same OpenShift cluster. Each business unit needs separate API Manager catalogs, developer portals, and analytics, with strict data isolation for regulatory compliance. What architectural approach best satisfies these requirements?

During a Cloud Pak for Integration upgrade, the Platform UI navigator becomes unavailable and shows CrashLoopBackOff status. Logs indicate: 'Error: ECONNREFUSED connecting to common-web-ui service'. The common-web-ui pods are running successfully. IAM authentication is functioning. What is the most probable cause and remediation?

A Cloud Pak for Integration environment uses App Connect Enterprise with MQ integration. The administrator needs to implement a solution where integration flows can process messages from MQ queues with exactly-once delivery semantics, ensuring no message loss during pod restarts or failures. The solution must support horizontal scaling of integration servers. What configuration approach ensures these requirements?

An administrator is configuring Event Streams (Kafka) within Cloud Pak for Integration for a financial services application requiring high throughput, low latency, and guaranteed message ordering per customer account. The cluster has 5 brokers. Topics will have varying message rates from 100 to 50,000 messages per second per topic. What configuration strategy optimally balances these requirements?

A Cloud Pak for Integration deployment on OpenShift is experiencing degraded performance across all components. Investigation reveals that etcd latency has increased from 5ms to 150ms during peak hours. The OpenShift cluster has 3 master nodes with etcd co-located, and the storage backend uses network-attached storage. What is the most effective remediation strategy?

An organization needs to implement API lifecycle management across development, test, and production environments in Cloud Pak for Integration. APIs must be promoted through environments with approval gates, configuration externalization, and the ability to rollback. Developer access should be restricted to lower environments. What is the recommended implementation approach?

A Cloud Pak for Integration environment uses Asset Repository to share integration assets across teams. After implementing custom asset types with extended metadata fields and establishing governance policies, users report that searches return inconsistent results and some assets with matching criteria are not appearing in search results. The Asset Repository pods are healthy and elasticsearch shows green status. What is the most likely cause and resolution?

An enterprise Cloud Pak for Integration environment requires implementing comprehensive backup and disaster recovery procedures. The environment includes API Connect, App Connect Enterprise, MQ, Event Streams, and Asset Repository. The RTO is 4 hours and RPO is 1 hour. All components use persistent storage. What backup strategy best meets these requirements while minimizing operational complexity?
