VMware Telco Cloud Automation Skills Intermediate Practice Exam: Medium Difficulty 2025

A telco operator is deploying VMware Telco Cloud Automation and needs to integrate with their existing OpenStack infrastructure for VIM management. The architecture requires separation of management and workload traffic. Which component configuration is essential for establishing this connectivity?

During Network Function (NF) onboarding in Telco Cloud Automation, a VNF package validation fails with descriptor errors. The VNFD references external virtual links that are not properly defined. What is the most appropriate approach to resolve this issue?

A Network Service Designer is creating a composite network service that includes both VNFs and CNFs. The service requires specific chaining between a virtualized firewall (VNF) and a containerized load balancer (CNF). Which Telco Cloud Automation capability must be configured to achieve this?

An operations team notices that a VNF instance is consuming excessive CPU resources and approaching capacity limits. They need to scale the VNF horizontally. What prerequisite conditions must be met in Telco Cloud Automation for successful auto-scaling?

A telco architect is designing a multi-site deployment of Telco Cloud Automation where network services must span across geographically distributed data centers. What architectural consideration is most critical for ensuring service continuity?

During a network service instantiation, the operation fails at the VNF configuration phase. Logs indicate that Day-0/Day-1 configuration scripts are not executing properly. The VNF package includes cloud-init configuration. What is the most likely cause and resolution?

A service designer needs to create a network service that requires specific affinity rules to ensure certain VNF components are deployed on the same compute host for performance reasons, while other components must be anti-affine for redundancy. How should this be implemented in Telco Cloud Automation?

An operator is troubleshooting performance issues with deployed network services. Monitoring data shows intermittent packet loss between VNF components. The VNFs are deployed across different compute nodes. What TCA monitoring and troubleshooting approach should be used first?

A telco provider needs to implement a blue-green deployment strategy for updating a critical network service without service interruption. The service includes multiple interconnected VNFs. What orchestration approach in Telco Cloud Automation best supports this requirement?

An operations team needs to set up comprehensive monitoring for deployed VNFs that can trigger automatic lifecycle actions based on specific performance metrics. The VNFs must scale out when CPU exceeds 80% for 5 minutes and scale in when CPU drops below 30% for 10 minutes. How should this be configured in Telco Cloud Automation?
