Question 3
SIMULATION
After the initial setup, a customer requested the administrator use active-active teaming and failover order for the vSAN and vMotion port groups. The customer currently has two uplinks and one distributed switch. Without accessing any hosts, use the simulator to remediate the configuration.
Answer : A
To configure active-active teaming and set the failover order for the vSAN and vMotion port groups on a distributed switch using the vSphere Client, follow these steps:
Log in to vSphere Client:
Open the vSphere Client.
Enter the username: administrator@vsphere.local.
Enter the password: VMw@r3!123.
Click Login.
Navigate to Networking:
From the home screen, click on Networking in the left-hand navigation pane.
Select the Distributed Switch:
Locate and select the distributed switch that the vSAN and vMotion port groups are using.
Edit vSAN Port Group Settings:
Right-click on the vSAN port group and select Edit Settings.
In the Edit Settings window, click on Teaming and Failover.
Configure Active-Active Teaming for vSAN:
In the Teaming and Failover section, you will see the list of uplinks.
Ensure that both uplinks are set as Active Uplinks.
To do this, drag the uplinks from the Unused Uplinks or Standby Uplinks section to the Active Uplinks section if necessary.
Ensure that no uplinks are in the Standby Uplinks section (all should be in Active Uplinks).
Set Failover Order for vSAN:
Ensure the failover order is correctly set to use both uplinks for active-active teaming.
Click OK to save the changes.
Edit vMotion Port Group Settings:
Right-click on the vMotion port group and select Edit Settings.
In the Edit Settings window, click on Teaming and Failover.
Configure Active-Active Teaming for vMotion:
In the Teaming and Failover section, ensure that both uplinks are set as Active Uplinks.
Drag the uplinks from the Unused Uplinks or Standby Uplinks section to the Active Uplinks section if necessary.
Ensure that no uplinks are in the Standby Uplinks section (all should be in Active Uplinks).
Set Failover Order for vMotion:
Ensure the failover order is correctly set to use both uplinks for active-active teaming.
Click OK to save the changes.
Verify Configuration:
Check the Networking section to verify that the changes have been applied correctly and that both port groups are using active-active teaming with the appropriate failover order.
VMware vSphere Networking Guide: vSphere Networking
=========================
These steps outline the process to configure active-active teaming and set the failover order for the vSAN and vMotion port groups without accessing any hosts directly. This ensures redundancy and efficient use of available network resources.
Question 4
SIMULATION
A VxRail administrator is planning a maintenance activity. The customer has a 2 hour maintenance window and wants to avoid unnecessary vSAN re-synchronization during this time.
Use the simulator to prepare the system for maintenance mode.
Answer : A
To prepare the system for maintenance mode and avoid unnecessary vSAN re-synchronization, follow these steps:
Log in to vSphere Client:
Open the vSphere Client.
Enter the username: administrator@vsphere.local.
Enter the password: VMw@r3!123.
Click Login.
Navigate to the Host:
In the vSphere Client interface, navigate to Hosts and Clusters.
Expand the VxRail-DC and then the VxRail-Cluster.
Select the Host for Maintenance:
Select the host you plan to put into maintenance mode (e.g., vcluster730-esx01.edu.local, vcluster730-esx02.edu.local, etc.).
Enter Maintenance Mode:
Right-click on the selected host and select Enter Maintenance Mode.
In the Enter Maintenance Mode window, you will have several options for vSAN data migration. To avoid unnecessary re-synchronization, choose Ensure Accessibility.
Ensure Accessibility: This option makes sure that the data remains accessible during maintenance but does not immediately trigger full data migration. It is the best choice to avoid unnecessary re-synchronization during a short maintenance window.
Confirm Maintenance Mode:
Click OK to confirm the selection and put the host into maintenance mode.
Verify the Host Status:
Monitor the status to ensure the host enters maintenance mode without triggering excessive re-synchronization.
VMware vSAN Maintenance Mode Options: vSAN Maintenance Mode
=========================
To summarize, selecting Ensure Accessibility when entering maintenance mode helps to avoid unnecessary vSAN re-synchronization during the maintenance window. This method ensures that data remains accessible and minimizes the impact on the cluster's performance and availability during the maintenance activity.

Question 6
SIMULATION
An existing 4-node VxRail standard cluster has to be scaled out with 2 additional nodes and
configured as a stretched cluster. An administrator must prepare a vSAN storage policy that should
have the following:
- vSAN Policy Name: vSAN
Stretched Cluster
- Data protection across the sites
- Local protection: RAID-1 with
FTT=1
- Thick Provisioning
An administrator should be able to provision a VM even if the currently available cluster
resources cannot satisfy the current policy.
Use the simulator to create the required vSAN storage policy.
Answer : A
To create the required vSAN storage policy in the vSphere Client for a VxRail stretched cluster, follow these steps:
Log in to vSphere Client:
Open the vSphere Client.
Enter the username: administrator@vsphere.local.
Enter the password: VMw@r3!123.
Click Login.
Navigate to Storage Policies:
From the home screen, go to Policies and Profiles in the left-hand navigation pane.
Click on VM Storage Policies.
Create a New Storage Policy:

Click Next.
Add vSAN Rules:
In the Storage Compatibility section, click Add rule and select vSAN.
Configure the following:
Primary level of failures to tolerate (PFTT): 1 failure - RAID 1 (Mirroring)
Secondary level of failures to tolerate (SFTT): 1 failure - RAID 1 (Mirroring)
Failures to Tolerate: 1
Provisioning type: Thick Provisioning
Ensure 'Force Provisioning' is enabled. This allows the VM to be provisioned even if the current resources do not satisfy the policy.
Set Data Services:
Skip the Data Services section if not applicable.
Click Next.
Review and Finish:
Review the policy settings.
Click Finish to create the storage policy.
Apply the Storage Policy to VMs:
Navigate to the VMs section.
Select the VMs that need the new storage policy.
Right-click and select VM Policies > Edit VM Storage Policies.
Choose the vSAN Stretched Cluster policy for the applicable disks.
