VMware Telco Cloud Automation Skills Practice Exam 2025: Latest Questions

An operator is adopting VMware Telco Cloud Automation (TCA) to manage CNFs across multiple sites. Which statement best describes the role of TCA in the architecture?

A vendor provides a CNF package to be onboarded into TCA. Which package characteristic is most important to enable automated deployment and lifecycle operations?

A service designer wants a service to be reusable across multiple sites with different IP subnets and VLAN IDs. Which approach is the best practice?

After a CNF instantiation, an operator needs to quickly confirm whether the network function is healthy from TCA’s perspective. What is the most direct item to check first?

A CNF onboarding fails validation in TCA because required images cannot be pulled during test deployment. The organization uses a private container registry. What is the most likely cause?

A team is designing a composite service that includes two network functions with a dependency: NF-B must start only after NF-A is ready. Which service design capability best addresses this requirement?

An operator wants to limit which infrastructure clusters can be selected for a particular CNF because it requires SR-IOV and hugepages. Which is the best way to enforce this in an automated manner?

A service instantiation succeeds, but traffic does not flow between the CNF and an external network. Kubernetes pods are Running. Which check is most appropriate to perform first from a TCA/telco orchestration perspective?

A CNF is designed to be scaled out during peak traffic. The operator wants scaling to be driven by telemetry (e.g., CPU utilization) while maintaining control and auditability. What is the most appropriate design approach?

After onboarding a network function, instantiation fails with an error indicating insufficient hugepages, even though the cluster has hugepages configured on some nodes. What is the most likely reason?

An operations team wants to let service designers create and test Network Service templates without affecting production inventory or orchestrated services. Which approach best meets this requirement in VMware Telco Cloud Automation?

A VNF package has been onboarded, but instantiation fails during validation with an error indicating missing image artifacts. Which is the most likely cause?

Which component in Telco Cloud Automation is primarily responsible for persisting the modeled entities such as Network Services, VNFs/CNFs, and their lifecycle states?

A Network Service requires a CNF to be deployed across two Kubernetes clusters for resiliency. The service designer wants placement to be controlled from the template without manually selecting a cluster at request time. What is the best design approach?

A CNF onboarding attempt fails because the platform cannot pull container images at deploy time. Other CNFs work. The registry credentials were recently rotated. What is the most appropriate corrective action?

An administrator wants to expose a service catalog item to multiple teams while preventing those teams from modifying the underlying service template. Which approach is recommended?

A service instantiation fails after IP allocation with an error indicating an exhausted pool. What is the best next step to restore successful deployments with minimal disruption?

A designer is modeling a network service that includes a Day-2 operation to rotate application credentials inside a CNF. Which method best aligns with Telco Cloud Automation best practices for secure automation?

A CSP is designing for high availability of the Telco Cloud Automation control plane. Which design choice most directly improves resiliency of the orchestration service state and avoids single points of failure?

A multi-site Network Service is designed to deploy VNFs on vSphere at Site A and CNFs on Kubernetes at Site B. During instantiation, the CNF deploys successfully but the VNF fails due to missing network mappings. What is the most appropriate long-term fix?

An operator is onboarding a new VNF package into Telco Cloud Automation. The import succeeds, but the VNF cannot be instantiated because required configuration inputs are missing. Which onboarding best practice most directly prevents this issue?

A service designer needs to chain three network functions (FW -> DPI -> NAT) and allow a single service blueprint to deploy in multiple sites with different IP pools and VLAN IDs. Which design approach is most appropriate?

A Telco Cloud Automation deployment uses Role-Based Access Control (RBAC). A tenant administrator should be able to instantiate and scale services but must not be able to onboard or modify VNF packages. Which RBAC pattern best meets the requirement?

After a planned maintenance window, service instantiation begins failing intermittently. Telco Cloud Automation shows timeouts when communicating with the NFV infrastructure endpoint, while other APIs appear responsive. Which troubleshooting step is the most appropriate first action?

An operator wants to reduce service impact when upgrading a stateful VNF deployed as part of a service. The goal is to keep the service available while updating VNF software and minimizing manual steps. Which approach is the best fit?
