VMware Telco Cloud NFV Skills Practice Exam: Test Your Knowledge 2025

An organization is designing a VMware Telco Cloud Infrastructure to support multiple Virtual Network Functions (VNFs). They need to ensure resource isolation between different tenants while maximizing hardware utilization. Which component is primarily responsible for providing multi-tenancy capabilities?

A telco operator is deploying VNFs that require SR-IOV for high-performance packet processing. During the deployment, the VNF fails to start, and logs indicate that the requested SR-IOV virtual functions are not available. What is the most likely root cause?

What is the primary function of the VNF Manager (VNFM) in an NFV architecture?

A service provider needs to implement network segmentation for VNFs handling different security zones (DMZ, internal, management). Which NSX-T component should be configured to enforce security policies between these zones?

During a VNF scaling operation, the orchestrator reports that the scaling action failed due to insufficient compute resources. Where should the administrator first investigate to determine resource availability?

A telco operator is implementing a VNF that requires DPDK (Data Plane Development Kit) for high-throughput packet processing. Which configuration is essential to ensure optimal DPDK performance?

An administrator needs to configure affinity rules for a VNF composed of multiple VMs that must run on the same ESXi host for performance reasons. Which vSphere feature should be used?

A service provider is experiencing intermittent connectivity issues with VNFs deployed across multiple Edge Clusters. Network traces show that GENEVE tunnel endpoints are occasionally unreachable. What should be verified first to resolve this issue?

Which component in the VMware Telco Cloud platform is responsible for maintaining the VNF catalog and managing the lifecycle of VNF packages?

A VNF deployment requires anti-affinity rules to ensure high availability by distributing VNF instances across different physical hosts. However, when trying to power on the third instance, the operation fails. What is the most likely cause?

An organization wants to implement automated healing for VNF instances that become unresponsive. Which combination of components is required to achieve this functionality?

What is the purpose of the VMware Integrated OpenStack (VIO) component in a Telco Cloud Infrastructure deployment?

A telco operator needs to deploy a VNF that requires direct access to physical network interfaces for performance reasons, bypassing the virtual switch. Which technology should be implemented?

During a VNF onboarding process, the administrator needs to validate the VNF descriptor file before deployment. Which information is typically NOT included in a VNF descriptor (VNFD)?

A service provider is designing network connectivity for VNFs that require both management traffic and high-speed data plane traffic. What is the recommended best practice for network architecture?

An administrator is troubleshooting a VNF that is experiencing packet loss on its data plane interfaces. The VNF is configured with NUMA awareness. What should be verified to ensure optimal NUMA configuration?

Which VMware component provides performance monitoring, capacity planning, and troubleshooting capabilities specifically for VNF deployments in a Telco Cloud environment?

A telco operator needs to implement BGP peering between VNFs and external routers for dynamic routing. Which NSX-T component should be configured to establish these BGP sessions?

What is the primary advantage of using Container Network Functions (CNFs) compared to traditional Virtual Network Functions (VNFs) in a Telco Cloud environment?

A VNF requires guaranteed network bandwidth of 10 Gbps for its data plane interface. The administrator needs to configure bandwidth reservation to ensure this requirement is met. What is the appropriate mechanism to implement this in a VMware environment?
