VMware Certified Specialist - VMware Cloud Foundation Deployment Advanced Practice Exam: Hard Questions 2025

A customer is designing the VCF management domain to meet strict separation-of-duties requirements. They want vCenter and NSX management to remain available during planned maintenance of a single host, but they also want to minimize the number of hosts due to licensing constraints. Which management domain design best meets these requirements while aligning to VCF best practices?

An organization wants to use a dedicated NSX overlay for application workloads while ensuring that management traffic (SDDC Manager, vCenter, NSX managers, vSAN) remains isolated and does not traverse overlay. During design review, an architect proposes placing the NSX Edge nodes for the first workload domain in the management domain cluster to "save hosts". What is the most accurate assessment of this proposal?

During VCF planning, a customer has two top-of-rack switches and requires that any single switch failure must not interrupt host management connectivity, vSAN traffic, or NSX overlay transport for any domain. They are debating between (1) LACP to a vSphere Distributed Switch with a multi-chassis LAG (MC-LAG) on the switches, and (2) vSphere standard active/standby NIC teaming using separate uplinks to each switch with no port-channel. Which choice is generally the safer, lowest-risk design for VCF bring-up and ongoing operations?

A customer is planning IP addressing for multiple VCF workload domains. They want to re-use the same NSX host TEP IP pool across two workload domains to conserve IP space. The domains will have separate vCenters but connect to the same physical underlay and will eventually require cross-domain routing via NSX Tier-0. What is the best practice recommendation?

During bring-up of a new VCF instance, SDDC Manager prechecks fail for multiple hosts with a message indicating that the host cannot be commissioned due to inconsistent DNS reverse lookup results for the management IP addresses. Forward lookups resolve correctly. Which corrective action most directly addresses the root cause while aligning to VCF prerequisites?

You are deploying the first VI workload domain. NSX deployment succeeds, but creating the required transport node profiles fails, and hosts remain in "Not Configured" state for NSX. Investigation shows the physical network allows only the management VLAN; the TEP VLAN is not trunked to the host uplinks. What is the fastest remediation path that preserves VCF automation and minimizes rework?

A VCF deployment is configured with vSAN in the management domain. After expanding the cluster with new hosts, the vSAN health check reports a mismatch in disk group configuration compared to existing hosts, and SDDC Manager shows the expansion task completed with warnings. The new hosts were imaged separately and may have different controller modes. What is the best next step to ensure long-term supportability and consistent performance?

An administrator runs an SDDC Manager workflow to rotate passwords for multiple SDDC components. The task fails midway, and now some components accept the new password while others still require the old password. Access to vCenter works with the new credential, but NSX Manager still requires the old credential, and subsequent lifecycle tasks fail. What is the best corrective action to restore a consistent, supported state?

A workload domain cluster is nearing capacity. The operations team wants to add hosts, but they also need to ensure that the added hosts will not cause lifecycle management issues later. They have a set of servers that are similar but use a different NIC model than the existing hosts. What should be validated first to minimize the risk of failed future upgrades and remediation operations in VCF?

After a successful VCF bring-up, the customer integrates an external corporate CA. Later, certificate replacement is performed manually on a subset of components (vCenter and one NSX Manager node). Shortly after, SDDC Manager health checks report certificate trust issues, and some API-driven workflows fail intermittently. What is the most appropriate remediation strategy?
