What is the number of SDDC Manager controller instances that can fail in a highly available VMware Cloud Foundation federation?
In a highly available VMware Cloud Foundation federation, there are typically three SDDC Manager controller instances. For high availability to maintain quorum and continue functioning, it can tolerate the failure of one instance out of the three. This means the system can sustain one failure and still operate, thereby the correct number of SDDC Manager controller instances that can fail is 1.
An administrator needs to install certificates for the VMware Cloud Foundation components. They need to be fully automated and not require additional configuration.
Which two certificate authority types meet these requirements? (Choose two.)
The two certificate authority types that meet the requirements of being fully automated and not requiring additional configuration for VMware Cloud Foundation components are Microsoft CA and OpenSSL CA. Microsoft CA can integrate directly into a Windows environment, enabling automated certificate management. OpenSSL CA can be used for internal processes and can be automated through scripting for seamless integration. Other certificate authority types mentioned do not provide the same level of automation and may require additional manual configuration.
An administrator has to work with multiple VMware Cloud Foundation sites, and Multi-Instance Federation is setup.
How can the administrator access different sites?
The administrator can access data across all sites from any node in a VMware Cloud Foundation Multi-Instance Federation setup. This means information from all instances can be viewed from any member node within the federation without needing to log in to each individual site.
Why is the Pass-Through mode preferred over HBA mode for disks connected to RAID controller in a vSAN environment?
Pass-Through mode is preferred over HBA mode for disks connected to a RAID controller in a vSAN environment because it allows individual disks to be hot-replaced without needing to reboot the ESXi host. This minimizes downtime and improves the overall manageability of the storage system. In contrast, other modes such as RAID0 may require a host reboot when changing disks.
What are the minimum hardware requirements to host VMware Cloud Foundation infrastructure components within the management cluster?
The minimum hardware requirements to host VMware Cloud Foundation infrastructure components within the management cluster are 4 vSAN Ready Nodes with two 10 GbE NICs and optionally one 1 GbE BMC NIC. A management cluster typically needs a minimum of 4 nodes to ensure high availability and fault tolerance. The 10 GbE NICs provide the necessary network bandwidth for the infrastructure components to operate efficiently.
