1. Question 1 · 99 in bank

   Which selection is optional when deploying a new virtual machine in the vSphere Client?

   • AData center
   • BCompute resource
   • CGuest OS
   • DFolder

   Show answer

   Answer: D

   Explanation

   A. Data center is correct. Data center is not even an option when creating a new VM in vCenter. When creating a new VM in vCenter the steps are: 1. Select a creation type 2. Select a name and folder 3. Select a compute resource 4. Select storage 5. Select compatibility 6. Select a guest OS 7. Customize hardware 8. Ready to complete

   Which piece of information does vSphere DRS consider when making decisions about which host to place a virtual machine?

   • AStorage bandwidth on the host
   • BNetwork usage by the virtual machine
   • CNetwork bandwidth on the host
   • DDisk usage by the virtual machine

   Show answer

   Answer: C

   Explanation

   I guess C answer is correct one. Host Network Saturation Threshold As mentioned earlier, DRS will avoid a network loaded host during load balancing decisions, only if its network utilization is beyond a certain threshold. This threshold is set to 80% by default. So, unless the host network utilization is above 80%, DRS considers the host to be a good candidate in terms of network resource availability. If a host’s network utilization is at or above the saturation threshold, DRS considers it to be network saturated. If all the hosts in the cluster are network saturated, DRS will prefer not to migrate VMs with network load, since migrating network loaded VMs to an already network saturated host would result in further degradation of VM performance. When DRS cannot migrate VMs due to this behavior, this can sometimes result in an imbalanced cluster

4. Question 4 · 99 in bank

   Which vSphere feature provides continuous availability, allowing users to protect any virtual machine from a host failure with no loss of data or connectivity?

   • AvSphere Fault Tolerance
   • BvSphere vMotion
   • CEnhanced vMotion Compatibility
   • DvSphere HA

   Show answer

   Answer: A

   Explanation

   Please disregard the previous answer! A. vSphere Fault Tolerance. vSphere Fault Tolerance (FT) is a feature in VMware vSphere that provides continuous availability for virtual machines. It protects virtual machines from host failures by creating a live secondary copy of the virtual machine that runs on another host in the same cluster. In the event of a host failure, the secondary copy takes over and continues to run, ensuring that there is no loss of data or connectivity. vSphere FT provides a high level of data protection and allows users to continue working even if a host fails, making it an ideal solution for critical applications that require high availability.

5. Question 5 · 99 in bank

   A vSphere administrator has multiple virtual machines running on a VMFS datastore. Which setting prioritizes the disk access for the virtual machines?

   • ADisk Shares
   • BDisk Mode
   • CHard disk
   • DDisk type

   Show answer

   Answer: A

   Explanation

   A. Disk Shares. In vSphere, the administrator can prioritize disk access for virtual machines by setting disk shares. Disk shares allow the administrator to set a relative priority for virtual machine disk access to the physical storage resources. The virtual machine with a higher number of disk shares is allocated a greater proportion of available I/O operations. This way, the administrator can ensure that the most critical virtual machines receive the necessary disk resources.

6. Question 6 · 99 in bank

   A developer is concerned about a virtual machine's CPU usage over the past month. How can an administrator show the CPU usage over this time period to the developer?

   • ASelect the VM's Summary tab, then view the VM Hardware pane.
   • BSelect the VM's Summary tab, then view CPU Usage.
   • CSelect the VM's Monitor tab, then select Overview.
   • DSelect the VM's Monitor tab, then select Events.

   Show answer

   Answer: C

   Explanation

   To display the CPU usage of a virtual machine over the past month to the developer, the administrator can follow these steps: C. Select the VM's Monitor tab, then select Overview. In the vSphere Client, navigating to the Monitor tab and choosing Overview allows the administrator to access performance monitoring and graphs for the selected virtual machine. This view provides various performance metrics, including CPU usage, over a defined period. By selecting the desired time range (in this case, the past month), the administrator can display the historical CPU usage of the VM for the specified duration. This information can be shared with the developer to address concerns about the virtual machine's CPU usage over the past month.

7. Question 7 · 99 in bank

   Which sequence of steps must a vSphere operator take to create an NFS datastore for a host, a cluster, or a data center?

   • AFrom the Datastores tab, select NFS > New Datastore
   • BSelect an ESXi host, click the Configure tab > Storage Devices
   • CFrom the Actions drop-down menu, select NFS > New Datastore
   • DRight-click on an ESXi host, select Storage > New Datastore

   Show answer

   Answer: D

   Explanation

   D. Right-click on an ESXi host, select Storage > New Datastore To create an NFS datastore in vSphere, an operator must perform the following steps: Right-click on an ESXi host, cluster, or data center in the vSphere inventory. Select Storage > New Datastore. In the New Datastore wizard, select NFS as the type of datastore. Follow the wizard's instructions to configure the NFS server and mount options. Complete the wizard to create the NFS datastore. Once created, the NFS datastore will be available for use by virtual machines running on the selected host, cluster, or data center.

   A VMware administrator monitoring a project has been advised to run the compute health check using the vSphere 7 client to monitor the ESXi hosts health. How should the administrator approach this task?

   • AHost > Monitor > Skyline Health > Expand Online Health Connectivity > Compute Health Checks > Retest
   • BHost > Monitor > Issues and Alarms
   • CMenu > Administration > Deployment > System Configuration
   • DHost > Monitor > Events

9. Question 9 · 99 in bank

   Which vSphere feature mitigates common optimization challenges?

   • AvSphere Trust Authority
   • BvSphere High Availability
   • CvSphere DRS
   • DvSphere Fault Tolerance

   Show answer

   Answer: C

   Explanation

   C. vSphere DRS (Distributed Resource Scheduler) vSphere DRS is a feature in vSphere that helps mitigate common optimization challenges by automating the distribution of workloads across multiple hosts in a vSphere cluster. It balances resources such as CPU, memory, and storage I/O across the cluster in real-time, ensuring that no single host becomes overutilized while others remain underutilized. By using vSphere DRS, administrators can improve the performance and utilization of their vSphere environment, while also providing a more stable and predictable infrastructure. Additionally, vSphere DRS can help reduce the risk of downtime by automatically migrating virtual machines to other hosts in the event of a host failure.

10. Question 10 · 99 in bank

    An administrator has configured a Linux virtual machine and found that it does not have network connectivity. The administrator notices this when trying to ping the default gateway and nothing comes back. The administrator needs to verify that the guest operating system is configured properly. What is the first step that the administrator should take to meet this goal?

    • AVerify that VMware Tools has been loaded on the guest operating system
    • BPing an outside source to see if you get a response
    • CConfirm the link status of the virtual switch
    • DCheck that the virtual network adapter is present and enabled

    Answer: D

    Explanation

    D is the correct answer! If you can't connect to the internet first thing you do is check the network adapter is selected and Connected checkbox is selected.
