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

A telecommunications provider is deploying VNFs across multiple availability zones in their VMware Telco Cloud Infrastructure. They need to ensure that the management and control plane components remain highly available even if an entire availability zone fails. Which architectural approach should they implement?

During the deployment of a VNF package using VMware Telco Cloud Automation, the instantiation process fails with an error indicating insufficient compute resources. The infrastructure has adequate CPU and memory, but the VNF requires SR-IOV capabilities. What is the most likely cause and solution?

An operations team needs to perform lifecycle management operations on multiple VNF instances simultaneously while maintaining service continuity. The VNFs are deployed in an active-active configuration behind a load balancer. What is the recommended approach for upgrading these VNFs?

A network service chain consists of a firewall VNF, DPI VNF, and load balancer VNF that must process traffic in a specific order. The environment uses NSX-T for network virtualization. Which NSX-T feature should be configured to ensure traffic flows through these VNFs in the correct sequence?

A telco operator needs to onboard a new VNF package into VMware Telco Cloud Automation. The VNF vendor has provided a CSAR package, but the onboarding process fails validation. Upon inspection, you find that the TOSCA descriptors reference custom node types. What steps are required to successfully onboard this VNF?

An NFV infrastructure is experiencing intermittent performance degradation for latency-sensitive VNFs. Analysis shows that some VNF instances are occasionally being vMotioned to different hosts during DRS operations. What combination of configurations should be implemented to optimize performance for these VNFs?

A telco cloud operator needs to implement network isolation between different tenant VNFs while allowing controlled communication between specific VNFs across tenant boundaries for shared services. Which approach best achieves this requirement using NSX-T?

During a planned maintenance window, an operator needs to evacuate all VNF workloads from a specific compute host for hardware upgrades. Some VNFs have strict anti-affinity rules with instances on other hosts. What is the correct sequence of operations to safely evacuate the host?

A VNF deployment requires three network interfaces: a management network, a data plane network with SR-IOV, and a signaling network with VLAN tagging. The deployment through TCA is failing during network attachment. What configuration elements must be properly defined for this VNF to deploy successfully?

A telco operator is designing a resilient infrastructure for critical VNFs that must survive both host failures and storage array failures. The infrastructure uses vSAN for storage. Which combination of features should be configured to meet these requirements?
