VMware 2V0-15.25 Practice Test Questions Answers

In VMware Cloud Foundation (VCF) Automation, eachAutomation Regionmust be associated with adedicated NSX Local Manager. A single NSX Local Manager instancecannot be reused across multiple Automation Regions.

In the provided scenario:

The existing environment hasWLD1andWLD2, both sharingone NSX Local Manager.

Region-1 in VCF Automation already consumes this shared NSX Local Manager.

When creatingRegion-2, the interface shows“No results”when selecting an NSX Local Manager.

This behavior matches documented VCF Automation constraints:an NSX Local Manager can only be mapped to a single Automation Region. Once it is consumed by one region, it isnot availablefor any additional region.

To create a second region (Region-2), anew NSX Local Manager instancemust exist in the environment. The only supported method to obtain a new NSX Local Manager is todeploy a new workload domain, because NSX Local Manager is deployed as part of every VI Workload Domain.

Thus, the administrator mustdeploy a new (third) workload domain, which includes its own NSX Local Manager package, allowing Region-2 to be created successfully.

The error message com.vmware.esx.settings.daemon.software.scan_spec (reconstructed from the typo setungs_aaemon.sonware.scan_spec) is a specific failure generated by thevSphere Lifecycle Manager (vLCM)compliance engine on the ESXi host.

Cause - Removed Component:This error is a documented known issue in vSphere 8.x/VCF 5.x+, specifically occurring when an administrator hasremoved a componentfrom the Cluster Image that the system validates as "required" or "structural" for the host's hardware configuration (common with hosts using DPUs or specific OEM add-ons).

The Scenario:The mention of "High CPU ready times" likely implies the administrator attempted to streamline the host image byremovinga perceived "bloatware" component (like a vendor monitoring agent or unused driver) to improve performance.

The Result:When vLCM attempts to build the "Scan Specification" (scan_spec) to validate the host against this modified image, the internal struct validation fails because the removed component creates an invalid dependency state, throwing the Invalid field software_spec... or scan_spec exception.

During VMware Cloud Foundation bring-up,time synchronization across all management components is mandatory. The VCF Installer, ESXi hosts, NSX Manager nodes, and vCenter must all sync tothe same NTP servers. If even one host or component has a time skew exceeding VMware’s allowed limits, VCF will report time sync errors during bring-up or post-deployment.

The administrator validated NTP configuration, DNS resolution, ping connectivity, and time synconly on the VCF Installer appliance, butdid not verify the ESXi hosts' time synchronization. NSX Manager obtains its time reference from the underlying ESXi host during deployment, so if the ESXi hosts are not synchronized with the same NTP sources, NSX Manager will drift, triggering the exact error described.

Option B (iptables) does not apply—the VCF Installer does not block outbound NTP by default.

Option C refers to workbook formatting, which would fail earlier in deployment—not after NSX Manager is running.

Option A is incorrect because ESXi should never use “host time sync”; NTP must be used.

In VMware Cloud Foundation 9.0 with vSAN ESA, storage policies must match the capabilities of the existing cluster. The scenario describes a5-node vSAN ESA clusterwhere the vSAN Default Storage Policy isRAID-1 (FTT=1). The administrator attempts to apply a2 Failures – RAID-6policy, which ESA supportsonly on clusters with at least 7 nodes. Because the cluster has only five nodes, the policy fails immediately—this is expected and documented in the vSAN ESA design specifications.

Since RAID-6 is not an option and capacity is low, the administrator must look for a method to reclaim storage usage without requiring additional nodes or unsupported policy changes. Converting VMs fromthick provisioning to thin provisioningis a safe and effective mitigation approach. Thin provisioning reduces consumed space by allowing disks to grow only as needed, immediately recovering unused blocks. This is a standard vSAN-supported method to temporarily alleviate capacity pressure.

Enabling encryption (A) or compression (D) doesnotreduce capacity usage retroactively and may actually increase overhead. Using RAID-5 (B) is also not possible because RAID-5 requiresat least 6 ESA-enabled hosts.

vDefend – Distributed Firewall is a security capability delivered byNSXwithin VMware Cloud Foundation. Although VCF components such as SDDC Manager, VCF Operations, and VCF Automation rely on licensing frameworks, the enforcement and activation ofNSX features—including Distributed Firewall—occur entirely withinNSX Manager.

To enablevDefend (Distributed Firewall), NSX Manager must detect a valid NSX license that includes security features. Without applying the correct license directly to NSX Manager:

The Distributed Firewall feature remains locked

vDefend cannot be enabled in workload domains

Security rules and micro-segmentation capability remain unavailable

VCF does not apply NSX security licensing at the SDDC Manager, VCF Automation, or VCF Operations layers. Instead, NSX Manager handles all feature entitlement checks internally.

Therefore, the new license must be installeddirectly in NSX Manager, under:

System → Licensing → NSX → Add License

Options A, C, and D are incorrect because none of those components control NSX feature activation.
