VMware Certified Advanced Professional - VMware Cloud Foundation 9.0 Operations Advanced Practice Exam: Hard Questions 2025

A VMware Cloud Foundation (VCF) environment uses a dedicated management domain and multiple VI workload domains. The security team mandates that east-west traffic between workload domains must be micro-segmented, while management components must remain reachable for lifecycle operations even during NSX reconfiguration. Which design best meets these requirements with the least operational risk?

A platform team must design network resiliency for a VCF workload domain that hosts latency-sensitive applications. Requirements: (1) tolerate a single TOR switch failure without losing host connectivity, (2) minimize convergence time, (3) avoid asymmetric routing issues for overlay traffic, and (4) maintain operational simplicity for day-2 changes. Which approach best fits these constraints?

After enabling vSAN encryption in a workload domain, operations notices an intermittent increase in VM latency during peak write activity. Storage policy and network health are unchanged. Which monitoring workflow most directly isolates whether the latency is caused by CPU contention from encryption overhead versus a storage backend issue?

A VCF workload domain experiences sporadic packet loss for a subset of VMs connected to an NSX overlay segment. Physical network shows no drops. The issue appears only when host CPU usage is high. Which advanced diagnostic step is MOST likely to confirm whether the packet loss is due to ESXi/NSX datapath scheduling (vs. physical network) without requiring an outage?

Operations observes that a newly expanded workload domain shows consistently higher VM read latency than before expansion. vSAN health is green, but performance service indicates increased resync activity during business hours. The cluster uses a tight maintenance window and must keep compliance with an availability SLA. Which change best reduces user-impacting latency while respecting SLA and operational constraints?

You must apply a critical security remediation across ESXi hosts in a VCF workload domain. Constraints: the cluster runs stateful services that cannot tolerate more than one host down at a time, vSAN is used with strict storage policy compliance, and the environment uses VCF lifecycle management. Which operational approach best meets these requirements while minimizing lifecycle drift?

A VCF administrator needs to rotate certificates for management domain components due to an expiring internal CA, but must avoid breaking trust between SDDC Manager, vCenter, NSX Managers, and integrated services. Which sequence is most appropriate to reduce risk of trust failures and failed LCM operations?

A new workload domain is commissioned with vSAN and NSX. During day-2 operations, the team must add hosts and ensure consistent configuration (networking, storage, and compliance) with minimal manual steps and auditable outcomes. Which approach best aligns with VCF operational best practices?

After a failed network change, SDDC Manager shows the workload domain as 'degraded' and cannot proceed with an update. vCenter is reachable, but NSX API calls from SDDC Manager time out. Operators confirm DNS resolves correctly and certificates are valid. Which troubleshooting step is MOST likely to identify the root cause quickly in an enterprise environment with strict change control?

A vSAN-backed workload domain reports intermittent 'object inaccessible' alarms during host maintenance operations, even though the team follows standard maintenance mode procedures. Investigation shows that some VMs use a storage policy requiring two failures to tolerate (FTT=2) but the cluster is small and frequently runs close to capacity. What is the MOST appropriate corrective action to prevent recurrence without reducing availability requirements?
