A vSphere cluster has the following configuration:
• Virtual machines (VMs) are running Production and Test workloads
• vSphere Distributed Resource Scheduler (DRS) is enabled
• There are no resource pools in the cluster
Performance monitoring data shows that the Production workload VMs are not receiving their fully allocated memory when the vSphere cluster is fully utilized.
A combination of which two steps could the administrator perform to ensure that the Production VMs are always guaranteed the full allocation of memory? (Choose two.)
Correct Answer:BD

An administrator needs to perform maintenance on a datastore that Is running the vSphere Cluster Services (vCLS) virtual machines (VMs).
Which feature can the administrator use in this scenario to avoid the use of Storage vMotion on the vCLS VMs?
Correct Answer:D
The feature that can be used to avoid the use of Storage vMotion on the vCLS VMs when performing maintenance on a datastore is vCLS Retreat Mode, which allows temporarily removing the vCLS VMs from the cluster without affecting the cluster services.

An administrator Is looking to deploy a new VMware vCenter Instance. The current environment consists of 75 hosts and is expected to grow up to 100 hosts over the next three years.
Which deployment size should the administrator select?
Correct Answer:D
VMWare: Small environment (up to 100 hosts or 1,000 virtual machines) Medium environment (up to 400 hosts or 4,000 virtual machine)
https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vcenter.install.doc/GUID-88571D8A-46E1-464 The administrator should select the small deployment size for the new vCenter Server instance, which is suitable for an environment with up to 100 hosts or 1,000 virtual machines. The small deployment size has 4 vCPUs and 19 GB of memory, which can handle the current and expected growth of the environment. The other deployment sizes are either too large or too small for the environment. References:

A group of new virtual machines have been deployed using thin-provisioned disks due to the limited storage space available in an environment. The storage team has expressed concern about extensive use of this type of provisioning.
An administrator is tasked with creating a custom alarm to notify the storage team when thin provisioning reaches a certain capacity threshold.
Where must the administrator define this alarm?
Correct Answer:A
To create a custom alarm to notify when thin provisioning reaches a certain capacity threshold, the administrator must define this alarm at the datastore level, as it is related to datastore usage.

An administrator is tasked with looking into the disaster recovery (DR) options for a software-defined data center (SDDC).
The following requirements must be met:
•All virtual machines (VMs) must be protected to a secondary site.
•The source VMs must remain online until the failover.
•When failing over to the secondary site, application downtime is allowed
•The DR failover must be managed from the vSphere Client.
•Costs must remain as low as possible.
How can the administrator accomplish this task?
Correct Answer:B

An administrator is tasked with configuring an appropriate Single Sign-On (SSO) solution for VMware vCenter based on the following criteria:
• The solution should support the creation of Enhanced Link Mode groups.
• All user accounts are stored within a single Active Directory domain and the solution must support only this Active Directory domain as the identity source.
• All user account password and account lockout policies must be managed within the Active Directory domain.
• The solution should support token-based authentication.
Which SSO solution should the administrator choose based on the criteria?
Correct Answer:A
„ In vCenter Server Identity Provider Federation, vCenter Server uses the OpenID Connect (OIDC) protocol to receive an identity token that authenticates the user with vCenter Server.“ Integrated Windows Authentication is deprecated since vSphere 7.0
