Question 1

An administrator needs to consolidate a number of physical servers by migrating the workloads to a software-defined data center solution.

Which VMware solution should the administrator recommend?



Answer : C

Option C is correct because VMware vSphere is the solution that provides a software-defined data center platform that can consolidate physical servers by migrating the workloads to virtual machines. Option A is incorrect because VMware Horizon is a solution for virtual desktop infrastructure (VDI) and application delivery. Option B is incorrect because VMware vSAN is a solution for software-defined storage that is integrated with vSphere. Option D is incorrect because VMware NSX is a solution for software-defined networking that is integrated with vSphere. Reference: https://www.vmware.com/products/vsphere.html


Question 2

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?



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)

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.

Question 3

An administrator needs better performance and near-zero CPU utilization from the ESXI hosts for networking functions and processing. The administrator creates a new vSphere Distributed Switch and enables network offloads compatibility.

Which solution would help achieve this goal?



Answer : B

The solution that would help achieve better performance and near-zero CPU utilization from the ESXi hosts for networking functions and processing is Data Processing Units (DPUs), which are specialized processors that offload network services from the CPU and provide hardware acceleration.

Question 4

An administrator is adding a new ESXi host to an existing vSphere cluster. When selecting the cluster, the administrator Is unable to use the Cluster Quickstart workflow to add and configure the additional host.

What could be the root cause of this issue?



Answer : A

Option A is correct because it indicates that the administrator has previously dismissed the Cluster Quickstart workflow, which will prevent them from using it to add and configure an additional host. To use the Cluster Quickstart workflow again, the administrator must enable it in the cluster settings. Option B is incorrect because the administrator does not need to manually add the host to the cluster before using the Cluster Quickstart workflow, as this is one of the steps in the workflow. Option C is incorrect because the administrator does not need any special permissions to use the Cluster Quickstart workflow, as long as they have permissions to perform cluster operations. Option D is incorrect because there is no option to enable the Cluster Quickstart workflow in VMware vCenter, as this is a feature of vSphere clusters. Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vcenterhost.doc/GUID-9F9E3F8C-0E2B-4B6A-8C5C-3F8E5F6B4E9D.html


Question 5

An administrator is investigating reports of users experiencing difficulties logging into a VMware vCenter instance using LDAP accounts.

Which service should the administrator check as part of troubleshooting?



Answer : C

Identity Management Service is the service that handles authentication requests from LDAP accounts and other identity sources in vCenter Server.


Question 6

Which feature would allow for the non-disruptive migration of a virtual machine between two clusters in a single VMware vCenter instance?



Answer : A

vSphere vMotion allows for the non-disruptive migration of a virtual machine between two clusters in a single vCenter instance, as long as there is shared storage and network connectivity between the clusters.


vMotion is used to move the VM to a different cluster within the same vCenter. This only works if both clusters share the same storage. If they don't you also need to perform a Storage vMotion. Cross vCenter Migration is only used to migrate to a different vCenter.

Question 7

A combination of which two components of the software-defined data center (SDDC) are responsible for the initial abstraction of CPU, memory, disk, and network resources and their subsequent management? (Choose two.)



Answer : A, D

VMware ESXi and VMware vCenter are the two components of the software-defined data center (SDDC) that are responsible for the initial abstraction of CPU, memory, disk, and network resources and their subsequent management1.VMware ESXi is the virtualization platform where you create and run virtual machines and virtual appliances2.VMware vCenter is the service through which you manage multiple hosts connected in a network and pool host resources2.These two components are part of the SDDC architecture that enables a fully automated, zero-downtime infrastructure for any application, and any hardware, now and in the future3.
