Installing, Configuring, and Setup · Identify the available CA options in SDDC Manager.
An organization wants to use its existing enterprise Certificate Authority (CA), which is based on Microsoft Active Directory Certificate Services (AD CS), to issue certificates for a new VCF environment. Which authentication type must be configured on the AD CS server to allow integration with SDDC Manager for certificate signing requests?
Show answer & explanation
Correct answer: C
For SDDC Manager to integrate with a Microsoft AD CS server, the Certificate Authority Web Enrollment role service must be installed and configured to use Basic Authentication. This allows SDDC Manager to programmatically submit Certificate Signing Requests (CSRs) using a service account's username and password.

Troubleshooting and Repairing · Identify the steps to perform checks and create log bundles with the SoS tool.
A new administrator joins a team managing a large VCF environment. They need to collect a comprehensive set of logs from SDDC Manager, vCenter, and the NSX Managers for a specific workload domain to send to VMware support. Which command-line utility should they use on the SDDC Manager appliance to perform this task?
Show answer & explanation
Correct answer: D
The Supportability and Serviceability (SoS) utility is the primary command-line tool used on the SDDC Manager appliance for health checks and log collection. The
sos --collect-logscommand, with appropriate flags for specific components and domains, gathers all necessary support bundles from the VCF management components and aggregates them into a single tarball for easy submission to VMware support. - Question 3Intermediate
Planning and Designing · Given a scenario, identify design considerations for workload domains with shared NSX Manager instances.
True or False: In a VMware Cloud Foundation Standard Architecture, the NSX Manager cluster deployed in the management domain can be shared with a new VI workload domain to manage its networking and security services.
Show answer & explanation
Correct answer: A
This is true. One of the design choices when creating a new VI workload domain is whether to deploy a new, dedicated NSX Manager cluster for it or to share the existing NSX Manager cluster from the management domain. Sharing the management domain's NSX Manager reduces management overhead and resource consumption, and is a common practice for many deployments.
- Question 4Intermediate
Administrative and Operational Tasks · Identify the steps to decommission hosts.
An administrator needs to decommission a host from a vSAN-enabled VI workload domain in SDDC Manager. What is the state of the host immediately after the 'Decommission Host' workflow completes successfully?
Show answer & explanation
Correct answer: B
The SDDC Manager 'Decommission Host' workflow automates several steps: it places the host into maintenance mode (ensuring vSAN data accessibility), evacuates VMs, removes the host from the vSAN cluster, and removes it from the VCF inventory. However, it does not remove the host from the vCenter inventory; the host becomes a standalone host within the data center object, disconnected from the cluster.

Administrative and Operational Tasks · Identify the characteristics of mapping between storage policies and Kubernetes storage classes.
A DevOps team is deploying stateful applications on a Tanzu Kubernetes Grid cluster within a VCF environment. They need to ensure that their Persistent Volume Claims (PVCs) are provisioned on high-performance storage. The VCF administrator has created a vSAN storage policy named 'Gold-Tier' that uses RAID-1 mirroring and has a high object space reservation. How can the administrator make this storage profile available to the DevOps team for their PVCs?
Show answer & explanation
Correct answer: B
The link between Kubernetes persistent storage requests and the underlying vSphere storage is the StorageClass object. The vSphere Container Storage Interface (CSI) driver reads the StorageClass definition. A vSphere administrator creates a StorageClass manifest (
.yamlfile) that references the specific vSAN storage policy by name. Once this StorageClass is applied to the Kubernetes cluster, developers can reference it in their PVC definitions to provision storage with the desired characteristics. - Question 6Beginner
Planning and Designing · Identify information required for the Planning and Preparation Workbook.
A consultant is filling out the Planning and Preparation Workbook for a new VCF on VxRail deployment. The customer requires that all management components (vCenter, NSX Manager, SDDC Manager) have both forward (A) and reverse (PTR) DNS records. Which section of the workbook is specifically designed to capture this information to ensure successful bring-up?
Show answer & explanation
Correct answer: A
The 'Hosts and Networks' tab of the Planning and Preparation Workbook contains the detailed sections for IP addresses, FQDNs, and VLANs for all infrastructure components. This is where the specific DNS A and PTR record details for SDDC Manager, vCenter, NSX Managers, and ESXi hosts are documented for pre-validation and use during deployment.
- Question 7Intermediate
Performance-tuning, Optimization, and Upgrades · Given a scenario, identify available options for online and offline bundle download using SDDC manager / vRSLCM.
A VCF environment is configured to use an offline bundle repository for all upgrades due to being in an air-gapped environment. An administrator has downloaded the latest VCF upgrade bundle and uploaded it to the internal repository. However, when they initiate a pre-check from the SDDC Manager UI, the new bundle is not visible. What is the most likely reason for this?
Show answer & explanation
Correct answer: D
After uploading a new offline bundle to the repository, the SDDC Manager must be triggered to rescan for available updates. A common and required step is to clear the download history within the SDDC Manager UI (under Repository > Bundle Management). This action forces SDDC Manager to re-read the repository manifest and discover the newly added bundle, making it available for pre-checks and upgrades.

Architecture and Technologies · Identify the characteristics of Spherelet.
What are two key functions of the Spherelet component in a vSphere with Tanzu environment? (Select TWO)
Show answer & explanation
Correct answers: A, C
- Question 9Intermediate
Planning and Designing · Identify workload domain prerequisites.
A healthcare provider is deploying a VCF environment and must use VMFS on FC as their principal storage for a new VI workload domain due to existing storage array investments. What is a key prerequisite that must be met before creating the workload domain in SDDC Manager?
Show answer & explanation
Correct answer: B
When using external storage like VMFS on FC as principal storage, VCF does not provision the storage itself. It is a prerequisite that the storage administrator has already created the LUNs, zoned them to the ESXi hosts intended for the workload domain, and created a shared VMFS datastore visible to all those hosts. The name of this existing datastore is then provided to SDDC Manager during the workload domain creation wizard.
- Question 10Beginner
Administrative and Operational Tasks · Given a scenario, identify how to manage passwords in VMware Cloud Foundation including supported components and options.
Which VMware Cloud Foundation component is primarily responsible for automating the rotation of passwords for vCenter, ESXi hosts, and NSX Managers?
Show answer & explanation
Correct answer: B
SDDC Manager contains the service responsible for managing the credentials of the components it deploys. It can perform automated password rotation based on configured policies, update expired passwords, and manage the credentials for core infrastructure like vCenter, ESXi, and NSX. This is a key function of its day-2 operational capabilities.
