VMware Telco Cloud NFV Skills Practice Exam 2025: Latest Questions

A CSP is designing a Telco Cloud NFV platform to host both VNFs and CNFs. They want a unified infrastructure layer with consistent lifecycle management across compute, storage, and networking. Which VMware component best fits this role in the architecture?

During planning, an architect wants to reduce fault domain impact so that a single host failure does not significantly affect VNF capacity for a critical service. Which design choice best supports this goal?

An operator needs to onboard a new VNF and ensure its deployment is repeatable across multiple sites with consistent parameterization (networks, IP pools, flavor sizing). Which approach is most appropriate?

A CNF running on Kubernetes requires controlled access to the Kubernetes API and least-privilege permissions for its service account. Which Kubernetes feature should be used to enforce this?

A VNF requires two isolated data networks (e.g., signaling and user plane) and one management network. The networks must remain separated even if they share the same physical uplinks. Which solution best meets this requirement in a VMware-based Telco Cloud?

After onboarding a VNF, instantiation fails because the VNF Manager cannot allocate the requested virtual network for one of the VNF connection points. Other VNFs instantiate successfully. What is the MOST likely cause?

Operations wants proactive alerting when NFVI resources approach exhaustion, and the ability to correlate alarms with impacted VNFs and clusters to speed troubleshooting. Which capability best addresses this requirement?

A CSP needs to perform maintenance on a compute host running multiple VNFs while minimizing service impact. What is the recommended operational approach?

A UPF-like workload requires consistent high throughput and low latency. The operator observes jitter and reduced packet rates during peak periods, even though CPU utilization appears moderate. Which configuration change is MOST likely to improve dataplane determinism?

A security team requires micro-segmentation so that only specific VNF components can communicate east-west, and policy must follow workloads even when they move across hosts. Which solution best satisfies this requirement in a VMware Telco Cloud environment?

A telco operations team wants a quick way to verify overall health of the Telco Cloud before onboarding a new VNF. Which approach best aligns with recommended operational practice?

In a Telco Cloud NFV environment, which vSphere feature is primarily used to keep a VNF running on a surviving host if an ESXi host fails?

A VNF requires strict separation of management traffic from tenant/data traffic. Which design best meets this requirement in a VMware-based Telco Cloud?

After deploying a VNF, the management system can ping the VNF’s management IP, but SSH and application ports are unreachable. The VNF VM is powered on and has the correct IP configuration. What is the MOST likely infrastructure-level cause?

A CNF (container network function) is deployed on Kubernetes in the Telco Cloud. The team needs to roll out a configuration change with minimal disruption and fast rollback. Which Kubernetes-native method best fits this requirement?

A VNF onboarding fails because the descriptor requests a network that does not exist in the target cloud. What is the BEST remediation approach to prevent repeated failures?

A telco wants to ensure that VNF workloads are protected from noisy neighbors and receive guaranteed CPU resources during peak hours. Which vSphere mechanism is MOST appropriate to meet this requirement?

A site uses multiple availability zones within a region. The design goal is to keep active and standby instances of a network function in different failure domains while still allowing automated placement. What is the BEST approach?

After a planned maintenance window, several VNFs experience intermittent packet loss on the data plane, but management connectivity is stable. The issue correlates with peak throughput periods. Which troubleshooting action is MOST likely to identify the root cause at the infrastructure layer?

A security audit requires tenant workloads (VNFs) to be isolated so that east-west traffic between tenants is blocked by default, while still allowing explicitly permitted service chains. Which approach BEST meets this requirement in a Telco Cloud using software-defined networking?

A telco is onboarding a new VNF that must run close to the radio edge. The architecture requires that the VNF’s worker nodes be scheduled only on a specific set of edge compute hosts while allowing control-plane services to remain centralized. Which Kubernetes capability is the BEST fit to enforce this placement requirement?

After deploying a CNF on Telco Cloud, its pods start but can only reach services within the same namespace. Cross-namespace service calls fail, and cluster DNS resolution works. Which Kubernetes feature is MOST likely blocking the traffic?

An operator plans maintenance on an edge cluster running latency-sensitive CNFs. The goal is to patch hosts while ensuring at least N replicas of each CNF remain available during draining/evictions. Which Kubernetes object MOST directly enforces this requirement during node maintenance?

A CNF requires a dedicated high-throughput data interface for the user plane and a separate management interface for OAM traffic. The design must use multiple network attachments per pod. Which Kubernetes mechanism is typically used to attach additional interfaces beyond the default pod network in telco CNF deployments?

A VNF running on Telco Cloud Infrastructure experiences intermittent packet loss on the data plane only during peak traffic. CPU and memory utilization are normal. The VNF uses a high-performance user-plane path and requires consistent low latency. Which underlying configuration issue is the MOST likely cause to investigate first?
