VMware Cloud Foundation 9.0 Support Sample Questions (Q17-Q22):NEW QUESTION # 17
An administrator is responsible for managing a VMware Cloud Foundation (VCF) Fleet that is configured as follows:
* Single VCF instance with a single workload domain.
* The Workload Domain has a single 5-node VMware vSAN Express Storage Architecture (ESA) cluster.
* The vSAN Default Storage Policy is configured as RAID1.
The administrator is alerted to the fact that storage capacity is running low and, to improve space efficiency, attempts to change the vSAN storage policy on a number of large virtual machines to a 2 Failures - RAID-6 policy.
The policy change is immediately rejected.
What should the administrator do to reduce overall capacity usage while waiting for new storage devices to arrive?
  • A. Convert the Virtual Machines from thick provisioning to thin provisioning.
  • B. Reconfigure the Virtual Machines to use a 1 Failure-RAID-5 Storage Policy.
  • C. Enable compression on the vSAN Default Storage Policy.
  • D. Enable encryption on the vSAN Default Storage Policy.
Answer: A
Explanation:
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 is RAID-1 (FTT=1). The administrator attempts to apply a2 Failures - RAID-6policy, which ESA supports only 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.

NEW QUESTION # 18
An administrator is troubleshooting network connectivity issues on a VMware ESX host configured with a dedicated VMware vSAN vSphere Distributed Switch (vDS) port group. The VMware vSAN vDS port group has two physical adapters and two uplinks assigned. After a failure of the active physical adapter, the vSAN vDS connection over the vSAN network was lost.
What is the cause of the issue?
  • A. VLAN tagging is not correctly configured on the vDS.
  • B. The vDS failover policy does not allow fallback.
  • C. A physical adapter is set to "Not Used" in the vDS configuration.
  • D. The vSAN storage policies are misconfigured.
Answer: C
Explanation:
In vSAN ESA or OSA networking configured through a dedicated vSphere Distributed Switch (vDS), each vSAN vmkernel port must have at least oneActivephysical uplink available at all times. The scenario describes a vDS withtwo physical adaptersandtwo uplinks, but after failure of the active uplink,vSAN traffic was lost. This only occurs when the second physical NIC isnot actually assigned to the vSAN port group-typically because its uplink is set to"Unused".
In such a misconfiguration:
* vSAN traffic only uses the single active uplink.
* When that uplink fails, vSAN hasno failover path, causing immediate connectivity loss.
Option A (storage policies) does not affect network uplink behavior.
Option B (VLAN tagging) could cause connectivity failure but would not suddenly break only after an uplink failure.
Option D (failover policy not allowing fallback) affects recovery order, not immediate redundancy.

NEW QUESTION # 19
An administrator has successfully created a new Organization for All Apps In VMware Cloud Foundation (VCF) Automation. When logging into the new organization using the first user account, only the Overview tab is visible.
What is a possible cause of this issue?
  • A. The first user account was assigned the Organization Administrator Role.
  • B. The first user account was assigned a Custom Role.
  • C. The first user account was assigned the Organization User Role.
  • D. The first user account was assigned the Organization Auditor Role.
Answer: C
Explanation:
This issue stems from an incorrect role assignment during the user creation process in VMware Cloud Director (VCF Automation).
Organization Administrator Role (Option D): This role grants full control, including visibility of the Administration tab (to manage users, groups, and settings), Data Centers, and Monitor tabs. If the user were an Admin, they would see all tabs.
Organization Auditor Role (Option A): This is a read-only role, but by definition, an Auditor can view anything an Organization Administrator can see (including the Administration settings), just without edit rights. Therefore, an Auditor would still see the Administration tab.
Organization User Role (Option B): This is a consumer-level role designed for deploying and managing vApps. By default, this role does not have access to the Administration tab or high-level organization settings.
If the organization is new and has no vApps or VDCs populated yet, a user with this role might see a very restricted view (effectively just a dashboard or "Overview") because they lack the rights to see the administrative configuration menus.
Conclusion: The fact that the "Administration" tab is missing (implied by "only Overview is visible") identifies the user as an Organization User (or a restricted Custom Role) rather than an Administrator or Auditor.

NEW QUESTION # 20
An administrator is tasked with replacing a VMware vCenter certificate in VMware Cloud Foundation (VCF) Operations with an external CA-signed certificate. The certificate import completes successfully but when running the certificate replacement task, it fails with the following error: Certificate replacement has failed...
The Certificate Chain validation failed due to 'Signature does not match' What is the possible cause of this issue?
  • A. The external CA is not trusted by VCF Operations.
  • B. The server certificate was copied to the wrong field.
  • C. The Certificate Signing Request (CSR) included the IP address of the vCenter.
  • D. The external CA is not accessible to VCF Operations.
Answer: B
Explanation:
When replacing certificates in VMware Cloud Foundation (VCF) Operations, the system performs strict certificate chain validation. The error shown:
"Certificate chain validation failed due to 'Signature does not match'" indicates that VCF Operations attempted to validate the presented certificate chain but detected that the server certificate did not correctly match the signing CA certificate. This occursmost commonly when the administrator pastes the server certificate and CA root/intermediate certificates into the wrong fields during import.
VCF requires the certificate bundle to be uploaded in the correct format:
* Server certificate# Server Certificate field
* Intermediate certificates# Intermediate Chain field
* Root certificate# Root CA field
If the chain order is wrong or the server certificate is mistakenly placed in an intermediate or root CA field, the cryptographic signature validation fails. This exact failure mode is documented in VMware certificate replacement workflows.
Option A is incorrect because including an IP address in a CSR does not invalidate chain signatures.
Option B is incorrect because an untrusted CA produces atrustfailure, not asignature mismatch.
Option C is unrelated: accessibility is not required for certificate validation.

NEW QUESTION # 21
An administrator Is responsible for managing a VMware Cloud Foundation (VCF) fleet. The administrator discovers intermittent performance issues with the supplemental storage (ISCSI) connected to VCF workload domain. The administrator discovers that the (iSCSI) target is reachable from most VMware ESX hosts, but some hosts consistently experience periods of slow I/O and connection drops.
Which two actions should the administrator take to diagnose and resolve this issue? (Choose two.)
  • A. Ensure all ESX hosts have the VMkernel port MTU set to 9000.
  • B. Examine the iSCSI VMkernel port on all affected ESX hosts for TCP retransmissions and checksum offload errors.
  • C. Ensure all ESX hosts have the VMkernel port MTU set to 1500.
  • D. Update the network plugin on the ESX host to the latest version.
  • E. Review the iSCSI target's configuration to ensure it's configured for maximum performance, including enabling CHAP authentication.
Answer: A,B
Explanation:
To diagnose and resolve the intermittent performance and connection drop issues with the supplemental iSCSI storage, the administrator should focus on network layer consistency and health, particularly regarding packet size (MTU) and delivery (TCP).
* Examine the iSCSI VMkernel port for TCP retransmissions (Action B - Diagnose):"Intermittent" connection drops and slow I/O are classic symptoms of packet loss or fragmentation issues. By examining the ESXi network stats (e.g., using esxtop key n or viewing vSphere performance charts) for TCP retransmissions, the administrator can confirm if packets are being dropped or lost in transit.
Checksum offload errorscan also indicate issues where the NIC hardware is incorrectly validating packets, causing the OS to drop them. This step identifies theroot cause(packet loss/corruption).
* Ensure all ESX hosts have the VMkernel port MTU set to 9000 (Action E - Resolve):For high- performance storage traffic like iSCSI in a VMware Cloud Foundation environment, it is best practice to useJumbo Frames (MTU 9000)end-to-end (Host -> Switch -> Storage Array).
* The symptom thatsomehosts are affected suggestsconfiguration driftwhere those specific hosts might be set to a different MTU (e.g., 1500) or are mismatched with the physical network/target (which is likely set to 9000 for performance).
* An MTU mismatch (e.g., Target sending 9000-byte frames to a Host/Switch expecting 1500) typically results in the "Do Not Fragment" (DF) bit causing packet drops, leading to the reported connection drops and retransmission delays. Ensuring a consistent MTU of 9000 across the fleet resolves this and aligns with VCF performance standards.
Note: Option A (CHAP) is for authentication security, not performance. Option C (Update network plugin) is a lifecycle task but less likely to be the immediate fix for "some hosts" having intermittent drops compared to the common issue of MTU mismatch. Option D (MTU 1500) would resolve drops if the physical network doesn't support Jumbo Frames, but would degrade performance, making E the preferred resolution for a
"performance" storage tier.
