NEW QUESTION # 23
A VM is configured with hard disks totaling 100 GB allocated The VM is using a RAID 5 vSAN Storage Policy What is the total space that is consumed on the vSAN Datastore?
- A. 166 GB
- B. 200 GB
- C. 133 GB
- D. 100 GB
Answer: C
Explanation:
When a VM is configured with hard disks totaling 100 GB and uses a RAID 5 vSAN Storage Policy, the total space consumed on the vSAN Datastore is approximately 133 GB. RAID 5 in vSAN requires additional space for parity, which is typically about 1.33 times the original data size. This means that for 100 GB of allocated space, the actual consumed space will be around 133 GB, accounting for the data and parity overhead.

NEW QUESTION # 24
A VxRail administrator is concerned about security and wants to protect the vSAN storage against unauthorized access (for both data on disk and in flight.) Use the simulator to enable the relevant services. A vSphere Native Key Provider has already been configured.
Answer:
Explanation:
To protect the vSAN storage against unauthorized access for both data on disk and in-flight, enable vSAN data-at-rest encryption and data-in-transit encryption. Follow these steps:
* Log in to vSphere Client:
* Open the vSphere Client.
* Enter the username:[email protected].
* Enter the password:VMw@r3!123.
* ClickLogin.
* Navigate to vSAN Cluster Settings:
* In the left-hand navigation pane, expandVxRail-DCand selectVxRail-Cluster.
* Click on theConfiguretab.
* Enable vSAN Data-at-Rest Encryption:
* Under thevSANsection, selectServices.
* Click onData-at-Rest Encryption.
* ClickEditto configure encryption settings.
* Ensure that theEnable Data-at-Rest Encryptioncheckbox is selected.
* Choose thevSphere Native Key Providerthat has already been configured.
* ClickApplyto enable data-at-rest encryption.
* Enable vSAN Data-in-Transit Encryption:
* Under the samevSANsection, selectServices.
* Click onData-in-Transit Encryption.
* ClickEditto configure encryption settings.
* Ensure that theEnable Data-in-Transit Encryptioncheckbox is selected.
* ClickApplyto enable data-in-transit encryption.
* Verify Configuration:

By enabling both data-at-rest and data-in-transit encryption, you can protect the vSAN storage from unauthorized access and ensure data security both on disk and during transit.
NEW QUESTION # 25
An administrator wants to get information about a specific host and runs this code:
GET/v1/hosts/{sn}
An API code 404 is returned
What is the reason for the error code?
- A. The administrator was not authenticated
- B. There was a server error
- C. The provided {sn} was not valid
- D. The API is designed to return all hosts in a cluster
Answer: C
Explanation:
The error code 404 indicates that the requested resource could not be found on the server. In the context of the API call GET/v1/hosts/{sn}, the 404 error is returned because the serial number (sn) provided was not valid or does not exist in the database. This means the server could not find any host that matches the provided serial number.
NEW QUESTION # 26
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:
Explanation:
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:[email protected].
* Enter the password:VMw@r3!123.
* ClickLogin.
* Navigate to Storage Policies:
* From the home screen, go toPolicies and Profilesin the left-hand navigation pane.
* Click onVM Storage Policies.
* Create a New Storage Policy:
* ClickCreate VM Storage Policy.
* Enter the name asvSAN Stretched Cluster.
* ClickNext.
* Configure Policy Rules:
* In thePolicy Structuresection, chooseEnable tag-based placement rulesif needed.
* ClickNext.
* Add vSAN Rules:
* In theStorage Compatibilitysection, clickAdd ruleand selectvSAN.
* 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 theData Servicessection if not applicable.
* ClickNext.
* Review and Finish:
* Review the policy settings.
* ClickFinishto create the storage policy.
* Apply the Storage Policy to VMs:
* Navigate to theVMssection.
* Select the VMs that need the new storage policy.
* Right-click and selectVM Policies>Edit VM Storage Policies.
* Choose thevSAN Stretched Clusterpolicy for the applicable disks.

User credentials are Username of
"[email protected]"
Password "VMw@r3!123".
Using the simulator, identify the correct node and remove it from the cluster.
Answer:
Explanation:
See the step by step solution in the Explanation below
Explanation:
To temporarily remove a node with a specific serial number from the VxRail cluster, follow these steps:
Log in to vSphere Client:
Open the vSphere Client.
Enter the username: [email protected].

Click Login.
Identify the Node with Serial Number "V0730040000000":
In the vSphere Client interface, navigate to the Hosts and Clusters view.
Expand the VxRail-DC and then the VxRail-Cluster.
Locate the Node:
Click on each host (e.g., vcluster730-esx01, vcluster730-esx02, vcluster730-esx03, vcluster730-esx04) and check the Summary tab to identify the node with the serial number V0730040000000.
The Summary tab provides details about the hardware, including the serial number.
Put the Node in Maintenance Mode:
Right-click on the identified node.
Select Maintenance Mode > Enter Maintenance Mode.
Select Ensure Accessibility and click OK.
Remove the Node from the Cluster:
Once the node is in maintenance mode, right-click the node again.
Select Remove from Inventory.
Confirm the action by clicking Yes or OK when prompted.
Verify the Node Removal:
Ensure that the node is no longer listed under the VxRail-Cluster.
Check the overall health and status of the cluster to confirm that it is functioning properly without the removed node.
