VMware 5V0-31.22 Practice Test - Questions Answers, Page 11

According to the VMware Cloud Foundation documentation1, the following audit tasks are performed and validation results are displayed on the UI:

JSON specifications validation: Validates the completeness and correctness of the specifications of JSON.

Well-Formed JSON File: Validates JSON correctness, syntax, null values, and missing fields or components.

Password validation: Validates specified passwords. Checks for minimum length, invalid characters, and format.

ESXi host version validation: Validates ESXi version installed on the hosts and compares against the VCF-EMS manifest located in /opt/evosddc/bundle/scripts/manifest.json on the Cloud Foundation Builder VM.

Cloud Builder Readiness: Validates whether the requirements to run the Cloud Foundation Builder VM are met.

License key format: Validates format, validity, and expiry for ESX, vSAN, vCenter Server, NSX, and Log Insight license keys.

ESXi Host Readiness

Network configuration: Validates CIDR to IP address validity, IP addresses in use, gateways, invalid or missing VLANs, invalid or missing MTU, and network spec availability for all components.

Time Synchronization: Validates the time on the components is synchronized with the NTP server in the SDDC Manager.

Network Connectivity: Validates network connectivity between hosts and between hosts and other components.

Stretched Cluster validation is not a configuration that is validated during the VMware Cloud Foundation bring-up process, because it is an optional feature that can be enabled after the bring-up process is completed2

Cloud Builder Log Configuration validation is not a valid option, because there is no such configuration in the VMware Cloud Foundation bring-up process.The Cloud Builder VM generates logs that can be downloaded for troubleshooting purposes, but they are not validated during the bring-up process3

NSX Edge validation is not a configuration that is validated during the VMware Cloud Foundation bring-up process, because NSX Edge nodes are not deployed during the bring-up process. They are deployed when creating a VI workload domain or enabling Application Virtual Networks (AVNs).

According to the VMware Cloud Foundation documentation1, each workload domain in VCF has its own NSX Manager cluster that provides network services and security policies for the workloads in that domain. Therefore, to meet the customer requirements, the solution will have two workload domains: PROD and DEV, each with its own NSX Manager cluster. Additionally, the management domain will also have its own NSX Manager cluster that provides network services for the management components in VCF.However, this NSX Manager cluster is not counted as part of the solution, because it is deployed by default during the VCF bring-up process and cannot be used for workload domains2

A) 1 is not a correct answer, because it implies that there is only one workload domain in the solution, which does not meet the customer requirement of having separate PROD and DEV workload domains.

B) 4 is not a correct answer, because it implies that there are four workload domains in the solution, which exceeds the customer requirement of having two environments: PROD and DEV.

D) 3 is not a correct answer, because it implies that there are three workload domains in the solution, which does not match the customer requirement of having two environments: PROD and DEV.

You create VI workload domains to run customer workloads. For each VI workload domain, you can choose the storage option - vSAN, NFS, vVols, or VMFS on FC.

VMware Cloud Foundation supports several storage types as principal and supplemental storage for VI workload domains. Principal storage is the initial shared storage type that is selected during the creation of a workload domain or cluster in SDDC Manager. Supplemental storage is the additional shared storage type that can be added after a cluster has been created using the vSphere Client.

The supported principal storage types for VI workload domains are:

vSAN

NFS v3

vVols (FC, iSCSI, or NFS)

The supported supplemental storage types for VI workload domains are:

vSAN

NFS v3 or v4.1

vVols (FC, iSCSI, or NFS)

VMFS on FC

iSCSI

NVMeoF/TCP

Therefore, the only option that contains only supported storage types for VI workload domains is B. NFS v3, NFS v4.1, vSAN.

VMWare Cloud Foundation Now Supports NVMeoF/TCP

To create a VI workload domain with VMFS on FC storage, the hosts must be commissioned with VMFS on FC as the storage type and must be associated with a vMotion only or vMotion and NFS network pool. https://docs.vmware.com/en/VMware-Cloud-Foundation/5.0/vcf-admin/GUID-4EBF9094-F732-4800-86FF-30C5D88B9758.html

To deploy a VI Workload Domain with VMFS on FC storage, the hosts must be associated with a network pool that contains the vMotion network information. This is because the vMotion network is required for adding a host to the SDDC Manager inventory and for migrating workloads between hosts.

A NFS only network pool, a network pool with vMotion and iSCSI, or an iSCSI only network pool are not valid options for deploying a VI Workload Domain with VMFS on FC storage. These network pools are used for different types of storage, such as NFS, vVols on iSCSI, or vSAN.

Hosts | VMware Cloud Foundation API Reference Guide APIs, section ''The hosts, if intended to be used for VMFS on FC, domain must be associated with either a NFS enabled or vMotion enabled network pool.''

https://docs.vmware.com/en/VMware-Cloud-Foundation/5.0/vcf-admin/GUID-2C3E06BA-7B77-4F4B-958C-1BFCB3E9CBA7.html Removing hosts from the SDDC Manager inventory is called decommissioning. If you want to re-use a host in a different workload domain, you must decommission, re-image, and commission the host before adding it to the workload domain. The hosts that you want to decommission must not be assigned to a workload domain. If a host is assigned to a workload domain, you must remove it before you can decommission it. See Remove a Host from a vSphere Cluster in a Workload Domain.

Use the decommission host workflow against a host with an unassigned state, re-image the host, and then run the commission host workflow.According to the VMware Cloud Foundation documentation1, removing hosts from the SDDC Manager inventory is called decommissioning. If you want to re-use a host in a different workload domain, you must decommission, re-image, and commission the host before adding it to the workload domain. The hosts that you want to decommission must not be assigned to a workload domain. If a host is assigned to a workload domain, you must remove it before you can decommission it.

The minimum number of hosts required for a new vSAN cluster is three, according to the VMware Cloud Foundation documentation1. This is because a vSAN cluster needs at least three hosts that contribute capacity to the cluster to form a quorum and tolerate failures.However, for best results and availability, VMware recommends adding at least four hosts to the cluster2

According to the VMware Cloud Foundation documentation1, the host you are adding must have the same type of principal storage as the existing hosts in the vSphere cluster. For VI workload domains, the host can use vSAN, NFS, VMFS on FC, or vVols for principal storage. A host using VMFS on FC will automatically use the same VMFS on FC configuration as the other hosts in the vSphere cluster.

Hosts with vSAN storage can be added to vSAN-based VI Workload domains, but not to VMFS on FC-based VI Workload domains. Hosts with vVols storage can be added to vVols-based VI Workload domains, but not to NFS-based VI Workload domains. Hosts with NFS storage can be added to NFS-based VI Workload domains, but not to VMFS on FC-based VI Workload domains.

The administrator can follow these steps to download the latest VCF software bundles:

Download the latest bundle transfer utility from myvmware.com.This is a tool that allows you to download the bundles from the VMware depot and upload them to the SDDC Manager appliance1

Use the utility to download the latest software bundles for the upgrade. You need to specify the version to which you are upgrading and provide your VMware Customer Connect credentials.The utility will verify the file size and checksum of the downloaded bundles1

Copy the bundles to SDDC manager using file sharing. You can use SCP or SFTP to transfer the bundles from your laptop to the SDDC Manager appliance.You need to upload the manifest file first, which is a metadata file that contains information about the VMware product versions included in the release Bill of Materials1
