During a planned maintenance window, an operator must patch ESXi hosts in an edge cluster running CNFs while minimizing service disruption. Which vSphere feature combination is most appropriate?

A security auditor requires proof that all administrative actions in the telco platform can be traced to an individual user and retained for investigations. Which control most directly satisfies this requirement?

A CNF deployment on an edge cluster experiences intermittent east-west packet loss only for certain pods. The issue disappears when those pods are rescheduled to different nodes. Which is the most likely first area to investigate?

An operator plans to host a UPF-like user plane CNF requiring very high packet throughput and low latency. They must minimize CPU overhead from virtualization while maintaining operational manageability. Which design choice is most appropriate?

A compliance policy mandates that management plane components (e.g., vCenter, Kubernetes API endpoints, automation services) must be reachable only from a restricted admin network, while CNF data plane networks must not have inbound access to management services. Which implementation best meets this requirement?

A service provider is planning a Telco Cloud Platform deployment across many far-edge sites with intermittent connectivity to the central data center. They need lifecycle management and policy consistency even when sites are temporarily disconnected. Which architectural approach best meets this requirement?

A platform administrator needs to validate that a newly onboarded CNF will be scheduled only on nodes that meet specific CPU feature requirements (e.g., advanced vector instructions). Which Kubernetes mechanism should the administrator check first?

An operator reports that after a node reboot at an edge site, several CNF pods remain in Pending state. The pods reference local persistent storage. What is the most likely cause?

A security team requires that CNFs cannot run as root and must not allow privilege escalation. Which Kubernetes feature is the best fit to enforce this requirement at the cluster level?

A new tenant requires strict traffic isolation between management, workload, and storage networks on Telco Cloud Platform. Which design choice best supports this requirement?

A platform engineer is automating Day-0 deployment for multiple edge clusters and wants repeatable provisioning with minimal drift. Which approach is most aligned with best practices?

A CNF vendor provides a Helm chart that deploys successfully, but the CNF fails its readiness checks because it cannot reach an external licensing server. The cluster is configured with default-deny egress policies. What is the most appropriate remediation?

A service provider requires that management-plane access to Telco Cloud Platform components be centrally audited and that administrators authenticate using corporate identity with role-based access. Which design best satisfies this requirement?

During an upgrade window, an operator observes that critical CNF pods are being evicted and rescheduled, causing brief service impact. The operator wants to minimize voluntary disruptions during node maintenance while still allowing necessary upgrades. What should be implemented?

A Telco Cloud Platform cluster hosts both latency-sensitive UPF CNFs and best-effort analytics workloads. The operator notices occasional CPU contention affecting UPF packet processing. Which scheduling/compute strategy is most appropriate to protect UPF performance?

An operations team wants the Telco Cloud Platform control plane to remain available during maintenance of a single host. Which design choice best supports this requirement?

A Telco Cloud Platform environment uses multiple networks for management, workload, and storage. What is the primary best-practice reason to separate these networks?

During onboarding of a new site, you must ensure that node-level settings for many servers are consistent and repeatable. Which approach best supports scalable deployment?

A platform administrator is asked to support compliance by ensuring that all administrative actions are traceable to an individual. Which control best meets this requirement?

After a maintenance window, several CNF pods remain in a Pending state on a Telco Cloud Platform cluster. Worker nodes show sufficient CPU and memory. Which is the most likely Kubernetes-level cause to check first?

A telco wants to enforce that only signed and approved container images can run in the cluster hosting CNFs. Which security capability best addresses this goal?

A new CNF requires low-latency packet processing and predictable CPU behavior. Which host and workload configuration is most appropriate?

A site is intermittently losing connectivity between management components and some hosts. The issue correlates with a physical switch reboot, after which traffic sometimes returns on a different uplink. Which configuration best prevents loss of management connectivity during such events?

A security audit requires proving that workloads running in one tenant cannot access another tenant's management plane resources. Which architectural control provides the strongest enforcement at the platform level?

A platform team wants to design for site survivability: if a site is partitioned from the central management plane, workloads at the site must continue to operate, and operations should reconcile cleanly when connectivity returns. Which approach best meets this requirement?

An operations team needs a quick way to verify whether a Telco Cloud Platform site is healthy after a maintenance window. Which check provides the most reliable first validation of platform readiness?

A Telco Cloud administrator must ensure that only signed container images can be deployed to clusters hosting CNFs. Which control best addresses this requirement?

A cloud operations engineer needs to provide CNF onboarding teams with a consistent way to consume platform services (e.g., logging, ingress) across multiple clusters. What is the most appropriate approach?

A Telco Cloud Platform deployment uses multiple availability zones. The architect wants Kubernetes control-plane and etcd components to tolerate a single-zone failure while minimizing split-brain risk. Which design is most appropriate?

A CNF requires SR-IOV and DPDK acceleration. During deployment, pods remain Pending with events indicating no matching resources. Which is the most likely cause?
