VMware Telco Cloud Platform Specialist Skills 2024 [v2] Advanced Practice Exam: Hard Questions 2025

A telco operator is deploying VMware Telco Cloud Platform with a distributed architecture across three geographically dispersed data centers. The management cluster experiences intermittent connectivity issues between sites, causing workload cluster reconciliation failures. CNF workloads remain operational but cannot be updated. Which architectural decision would BEST resolve this issue while maintaining high availability?

During a VMware Telco Cloud Platform deployment, the Harbor registry is experiencing certificate validation failures when workload clusters attempt to pull CNF images. The registry was configured with a custom CA-signed certificate, and the CA bundle was added to the TCA-CP (Telco Cloud Automation Control Plane) trust store. However, newly provisioned workload clusters still fail with x509 certificate errors. What is the MOST likely root cause requiring immediate remediation?

A 5G Core network function deployed on VMware Telco Cloud Platform is experiencing packet loss during high-traffic periods. The CNF uses SR-IOV for user plane interfaces. Performance monitoring shows CPU usage at 45%, memory at 60%, but the SR-IOV VF queue depth metrics indicate frequent drops. Network throughput is below expected performance. Which combination of actions would MOST effectively resolve this issue?

An organization is implementing zero-trust security for their VMware Telco Cloud Platform environment hosting multi-tenant VNFs and CNFs. They need to enforce microsegmentation between network functions while maintaining service chaining requirements for traffic flow through security VNFs. NSX-T is deployed. Which approach provides the MOST granular security while preserving required service insertion?

A VMware Telco Cloud Platform environment uses TCA-CP to manage multiple workload clusters across different availability zones. After a control plane certificate rotation, some workload clusters show 'NotReady' status in TCA-CP inventory, though the clusters themselves are operational and kubectl commands work directly. CNF updates initiated from TCA-CP fail. What is the MOST likely cause and solution?

A telco is designing a VMware Telco Cloud Platform architecture to support both IT workloads and 5G network functions with strict latency requirements (<1ms for user plane). The infrastructure includes servers with Intel CPUs supporting VT-x, VT-d, and EPA features. Which architectural configuration would BEST meet the latency requirements while maintaining operational flexibility?

During a VMware Telco Cloud Platform upgrade, the TCA-CP upgrade process fails at the 'Database Migration' phase with a timeout error. Logs indicate that the PostgreSQL database migration script is attempting to modify a large table with millions of records. The upgrade rollback completes successfully. Which approach provides the SAFEST path to successful upgrade completion?

A VMware Telco Cloud Platform deployment spans multiple Kubernetes workload clusters hosting various CNFs. The security team requires implementation of runtime security with continuous compliance scanning, vulnerability detection, and admission control based on image scan results. Which solution architecture would MOST comprehensively address these requirements while integrating with TCA-CP?

A telco operator experiences intermittent CNF pod failures with 'CrashLoopBackOff' status on specific worker nodes in a VMware Telco Cloud Platform workload cluster. The affected pods use SR-IOV network interfaces. Investigation reveals that pods fail only when scheduled on nodes that were recently cordoned and uncordoned for maintenance. The SR-IOV device plugin shows VF resources available. What is the MOST likely root cause?

An organization is designing disaster recovery for their VMware Telco Cloud Platform deployment that hosts stateful 5G Core network functions. The RTO is 15 minutes and RPO is 5 minutes. The deployment spans two sites 500km apart with dedicated dark fiber providing 10ms RTT. CNFs use persistent volumes for state. Which DR architecture would BEST meet these requirements?
