VMware Data Center Virtualization: Core Technical Skills Quiz Questions and Answers
Answer :
To prevent unauthorized access to the vSphere environment
Explanation :
The security networking policy in vSphere networking is designed to prevent unauthorized access to the vSphere environment. It includes features such as firewall rules, network isolation, and network traffic filtering.2. < 2 > Which vSphere cluster feature allows for automatic load balancing of VMs across ESXi hosts?A) vSphere DRSB) vSphere HAC) vSphere FTD) vSphere vMotionAnswer: A) vSphere DRSExplanation: vSphere DRS (Distributed Resource Scheduler) is a feature that allows for automatic load balancing of VMs across ESXi hosts. It ensures that VMs are running on the most suitable host based on resource availability and utilization.3. < 3 > What is the purpose of vSphere HA?A) To provide automatic load balancing of VMsB) To ensure high availability of VMs in the event of host failureC) To provide fault tolerance for critical VMsD) To enable live migration of VMs between hostsAnswer: B) To ensure high availability of VMs in the event of host failureExplanation: vSphere HA (High Availability) is a feature that ensures high availability of VMs in the event of host failure. It automatically restarts VMs on other hosts in the cluster to minimize downtime.4. < 4 > Which vSphere networking component is responsible for managing virtual switches and network adapters?A) vSphere ClientB) vCenter ServerC) ESXi hostD) vSphere Distributed SwitchAnswer: C) ESXi hostExplanation: The ESXi host is responsible for managing virtual switches and network adapters in vSphere networking. It is the component that runs the virtualization software and provides access to physical network resources.5. < 5 > What is the purpose of vSphere Distributed Switch?A) To provide automatic load balancing of VMsB) To ensure high availability of VMs in the event of host failureC) To enable live migration of VMs between hostsD) To manage network settings across multiple ESXi hostsAnswer: D) To manage network settings across multiple ESXi hostsExplanation: vSphere Distributed Switch is a fea
The benefits of creating vSphere clusters include high availability, load balancing, and resource pooling. Decreased network latency is not a benefit of creating vSphere clusters.2. < 2 > What is the purpose of vSphere Distributed Resource Scheduler (DRS)?A) To provide high availability for VMsB) To balance VM workloads across ESXi hostsC) To provide backup and recovery for VMsD) To manage VM snapshotsAnswer: B) To balance VM workloads across ESXi hosts. Explanation: vSphere Distributed Resource Scheduler (DRS) is a feature that automatically balances VM workloads across ESXi hosts in a vSphere cluster.3. < 3 > Which of the following is a requirement for enabling vSphere High Availability (HA)?A) At least two ESXi hosts in a vSphere clusterB) At least one VM in a vSphere clusterC) At least one vCenter Server in a vSphere clusterD) At least one datastore in a vSphere clusterAnswer: A) At least two ESXi hosts in a vSphere cluster. Explanation: vSphere High Availability (HA) requires at least two ESXi hosts in a vSphere cluster to provide high availability for VMs.4. < 4 > What is the purpose of vSphere Fault Tolerance (FT)?A) To provide high availability for VMsB) To balance VM workloads across ESXi hostsC) To provide backup and recovery for VMsD) To provide continuous availability for VMsAnswer: D) To provide continuous availability for VMs. Explanation: vSphere Fault Tolerance (FT) is a feature that provides continuous availability for VMs by creating a live shadow instance of a VM on a different ESXi host.5. < 5 > Which of the following is a requirement for enabling vSphere Distributed Resource Scheduler (DRS)?A) At least two ESXi hosts in a vSphere clusterB) At least one VM in a vSphere clusterC) At least one vCenter Server in a vSphere clusterD) At least one datastore in a vSphere clusterAnswer: A) At least two ESXi hosts in a vSphere cluster. Explanation: vSphere Distributed Resource Scheduler (DRS) requires at least two ESXi hosts in a vSphere c
To provide both high availability and load balancing for virtual machines
Explanation :
vSphere clusters are groups of ESXi hosts that work together to provide high availability and load balancing for virtual machines. By working together, ESXi hosts can provide valuable features to VMs, such as automatic failover in the event of a host failure and load balancing to ensure that VMs are evenly distributed across the cluster.
It can only be enabled on hosts running on Intel processors
Explanation :
This is a limitation of vSphere Fault Tolerance on vSphere 7.0. It is important to note that it can protect against both host and VM failures, and it does not require a dedicated network connection. Additionally, it can be enabled on hosts with vSphere Standard, Enterprise, or Enterprise Plus licenses, and on VMs with up to 8 vCPUs.
A) Right-click on the virtual machine and select "Add Permission " B) Navigate to the virtual machine's settings and select "Permissions " C) Use the vSphere Client to drag and drop the virtual machine onto the user or group you want to grant access to All of the above
Explanation :
You can add a permission to a virtual machine in vCenter Server by right-clicking on the virtual machine and selecting "Add Permission, " navigating to the virtual machine's settings and selecting "Permissions, " or using the vSphere Client to drag and drop the virtual machine onto the user or group you want to grant access to.
vSphere is a virtualization platform that is used to create and manage virtual machines. SDDC is a software-defined data center that uses virtualization to provide infrastructure services. vSphere is a key component of SDDC, providing the virtualization layer that enables the creation and management of virtual machines.
A measure of how well DRS is balancing the load across hosts
Explanation :
A DRS score is a value assigned to each host in a cluster that indicates how well DRS is balancing the load across all hosts. A higher score indicates that the host is underutilized and could handle more VMs, while a lower score indicates that the host is overutilized and may need to migrate VMs to other hosts.
vSphere is used to manage cloud computing resources
Explanation :
vSphere is a virtualization platform that is used to create and manage virtual machines. In a cloud computing environment, vSphere is used to manage the virtualization layer that provides the infrastructure for cloud computing services. This includes managing virtual machines, storage, and networking resources.
CPU shares determine the priority of a virtual machine's CPU usage, while CPU reservations guarantee a minimum amount of CPU resources for a virtual machine.
Explanation :
CPU shares determine the priority of a virtual machine's CPU usage, while CPU reservations guarantee a minimum amount of CPU resources for a virtual machine. This means that if there is contention for resources, the virtual machine with a CPU reservation will be guaranteed a minimum amount of CPU resources.
The process of deleting old snapshots to free up storage space
Explanation :
According to page 542 of the VMware Data Center Virtualization: Core Technical Skills course, snapshot consolidation is the process of deleting old snapshots to free up storage space. This is important because having too many snapshots can impact VM performance and consume valuable storage resources.
