Explanation
The two Elastic DRS policies that can be configured to meet the requirement of automatically scaling out and in based on resource demand are the Custom Elastic DRS policy and the Optimize for Rapid Scale-Out policy.
The Custom Elastic DRS policy allows you to configure the cluster to scale out when certain resource utilization thresholds are met, while the Optimize for Rapid Scale-Out policy allows you to configure the cluster to scale out when resource utilization is high and scale in when utilization is low.
Elastic DRS is a feature of VMware Cloud on AWS that enables automatic scaling of the cluster based on resource demand. To meet the requirement of automatic scaling, the administrator can configure a custom Elastic DRS policy or the Optimize for Rapid Scale-Out policy. Custom Elastic DRS policy allows administrator to define the custom rules for scale-out and scale-in based on resource utilization thresholds.
Optimize for Rapid Scale-Out policy automatically scales-out the cluster when resource utilization threshold is met.

Explanation
The statement that most accurately describes the service features of VMware Cloud on Dell EMC is C. An SDDC includes a minimum of one rack with three hosts. You can add hosts to the rack, up to the maximum supported by the rack. An SDDC consists of a rack with a minimum of three hosts, which can then be expanded up to the maximum supported by the rack. VMware Site Recovery is not included as part of the initial service offering.
VMware Cloud on Dell EMC provides a service that enables customers to run their VMware-based workloads on Dell EMC's hardware, in a jointly-engineered and fully-supported environment. The service allows customers to deploy a fully-configured VMware SDDC on Dell EMC VxRail or VxRack SDDC systems, with the option to add more hosts to the rack as needed.

Explanation
This role is designed to give administrators access to manage virtual machines, networks, and other settings within the folder. The CloudAdmin role will also give the junior administrators access to all global permissions that are associated with the Development folder.
"The CloudAdmin role is designed to give administrators access to manage a single folder. This role grants access to manage virtual machines, networks, and other settings within the folder. Additionally, this role grants access to all global permissions that are associated with the folder. Forexample, if the folder has global permissions that allow users to create or delete virtual machines, the CloudAdmin role will grant access to those permissions within the folder." The CloudAdmin user can grant other users or groups read-only access to VMware Cloud on AWS vCenter management objects such as the Mgmt-ResourcePool, Management VMs folder, Discovered Virtual Machines folder, vmc-hostswitch, and vsanDatastore. Because this read-only access does not propagate to management objects, you cannot grant it as a Global Permission and instead must explicitly grant it for each management object. VMware Cloud on AWS runs a script once a day that updates any newly-created management objects (such as objects in a new cluster) so that the CloudAdmin user and CloudAdminGroup SSO group have the updated role applied. The script itself does not grant additional access to any user or group, so you'll need to wait until it completes before the CloudAdmin can use this workflow to grant read-only access to those objects.

https://blogs.vmware.com/virtualblocks/2021/09/28/operational-air-gaps/ Operational isolation (operational "air-gapping") is critical to DR. VMware Cloud DR was designed from the very beginning for its systems and repository to be operationally isolated and for instantiating isolated recovery environments.
