A production VM experiences frequent CPU saturation, and DRS suggests migrations to rebalance the cluster.
What is the first step to confirm if CPU resource constraints are valid?
- A . Increase the VM’s CPU limit
- B . Check the CPU Ready metric in vCenter or vRealize Operations
- C . Disable HA to see if it affects performance
- D . Migrate the VM to a host with fewer VMs
B
Explanation:
CPU Ready time is a key metric reflecting how long a VM waits to be scheduled on a physical CPU. Monitoring this metric helps determine if CPU saturation is the genuine bottleneck before adjusting resource allocations or migrating VMs.
An administrator is configuring a newly provisioned workload domain within a VMware Cloud Foundation (VCF) environment. The workload domain will contain virtual machines hosting applications which are considered business critical, and the administrator wants to ensure that the virtual machines are given priority over other network traffic types.
Which three steps should the administrator perform to achieve this goal? (Choose three.)
- A . Configure a bandwidth resource allocation for the virtual machine traffic type.
- B . Enable Network I/O control (NIOC) on the workload domain vSphere Distributed Switch (vDS).
- C . Create a new vSphere Distributed Switch (vDS) specifically for virtual machine traffic.
- D . Configure dedicated physical network adapters for the ESXi management traffic.
- E . Disable bandwidth resource allocations for all other traffic types to ensure virtual machine traffic gets full bandwidth.
- F . Configure a new network resource pool to assign shares, limits and reservations for the virtual machine traffic.
A, B, F
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
According to the VMware Cloud Foundation 5.2 Administration Guide and the official vSphere Networking documentation, prioritizing virtual machine (VM) network traffic for business-critical applications in a VCF environment requires configuring Network I/O Control (NIOC) on the vSphere Distributed Switch (vDS), allocating bandwidth resources, and creating resource pools for VM traffic. Below are the exact extracts and official explanations:
Option A: Configure a bandwidth resource allocation for the virtual machine traffic type.
Extract from official VMware documentation:
“With Network I/O Control (NIOC) enabled on the vSphere Distributed Switch, you can allocate bandwidth to specific network resource types such as virtual machine traffic. Configuring bandwidth allocation ensures that business-critical VM traffic is prioritized on the physical network.” (VMware vSphere Networking Guide)
Option B: Enable Network I/O control (NIOC) on the workload domain vSphere Distributed Switch (vDS).
Extract:
“Network I/O Control must be enabled on the vSphere Distributed Switch to use features such as bandwidth allocation and resource pools. This allows you to guarantee minimum bandwidth and prioritize specific traffic types, including VM traffic.”
(VMware vSphere Networking Guide, VMware Cloud Foundation Administration Guide)
Option F: Configure a new network resource pool to assign shares, limits and reservations for the virtual machine traffic.
Extract:
“Network resource pools allow administrators to assign shares, limits, and reservations to virtual machine traffic on the vSphere Distributed Switch. This ensures that business-critical workloads receive the necessary network resources, even in times of contention.” (VMware vSphere Networking Guide)
Why Not the Other Options?
Option C: Creating a new vDS is not required specifically for prioritizing VM traffic; this can be done within the existing vDS.
Option D: While dedicated adapters can help with physical separation, they do not control network priority among traffic types within the vDS.
Option E: Disabling all other allocations is not recommended or supported and could disrupt other network operations.
Summary:
To ensure business-critical virtual machine traffic is prioritized over other types, the administrator should:
Enable NIOC on the vDS (B),
Configure bandwidth resource allocations for VM traffic (A), and
Create a new network resource pool to set shares, limits, and reservations for VM traffic (F).
These steps are outlined and supported by the official VMware Cloud Foundation and vSphere Networking documentation.
A newly deployed ESXi host fails to join vCenter Server due to a certificate mismatch.
Which vSphere component or service most likely handles certificate management?
- A . Auto Deploy
- B . Enhanced Linked Mode
- C . vSphere Certificate Manager
- D . vCenter Content Library
C
Explanation:
vSphere Certificate Manager is responsible for generating and managing certificates. Enhanced Linked Mode shares configuration between multiple vCenter Servers, Auto Deploy provisions ESXi hosts, and Content Library manages OVFs, ISOs, etc.
Which two steps should an administrator perform to configure the backup of the VMware Cloud Foundation (VCF) SDDC Manager and NSX components to allow them to be recovered in the event of a full site failure? (Choose two.)

- B . Configure the backup settings in SDDC Manager.
- C . Configure image-based backup for the NSX Manager cluster.
- D . Prepare an external SFTP server to store file-based backups.
- E . Define a scheduled task in vCenter to create a snapshot of the NSX Edge cluster.
B, D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
According to the official VMware Cloud Foundation 5.2 Administration Guide and VMware NSX Data Center documentation, the required and recommended steps to enable proper backup and recovery for the SDDC Manager and NSX Manager components are as follows:
Option B: Configure the backup settings in SDDC Manager.
Exact Extract from official documentation:
“You must configure backup settings in SDDC Manager to ensure scheduled, automated backups of critical SDDC Manager configuration and inventory data. Backups are stored as files that can be used to restore SDDC Manager in case of a failure or disaster.”
(VMware Cloud Foundation Administration Guide C Backing Up SDDC Manager)
Option D: Prepare an external SFTP server to store file-based backups.
Exact Extract from official documentation:
“Configure an external SFTP server to store SDDC Manager backup files. SDDC Manager supports only file-based backups using SFTP as the storage protocol.”
(VMware Cloud Foundation Administration Guide C Configuring Backup Destinations)
Why Not the Other Options?
Option A: Exporting an archive file from NSX Manager is a manual method and does not constitute a complete, restorable backup suitable for full site failure recovery.
Option C: Image-based backups for NSX Manager are not supported and can cause issues with the integrity and recoverability of NSX appliances, as per VMware best practices.
Option E: Snapshots of the NSX Edge cluster are not supported for backup and recovery; VMware specifically advises against using snapshots for backup purposes of NSX appliances.
Summary:
The administrator must configure the backup settings in SDDC Manager (B) and prepare an external SFTP server (D) to enable secure, automated, and restorable backups of SDDC Manager and NSX components, as recommended and required by the official VMware Cloud Foundation 5.2 documentation.
