Nutanix NCM-MCI-6.10 Exam : Nutanix Certified Master - Multicloud Infrastructure (NCM-MCI)

Correct Answer:

First, you need to open the Prism Central CLI from the Windows Server 2019 workstation. You can do this by clicking on the Start menu and typing "Prism Central CLI". Then, you need to log in with the credentials provided to you.
Second, you need to run the two commands that I have already given you in Desktop\Files\Network\flow.txt.
These commands are:
net.update_vpc_traffic_config virtual_switch=vs1 net.update_vpc_east_west_traffic_config permit_vpc_traffic=true These commands will update the virtual switch that carries the VPC traffic to vs1, and update the VPC east- west traffic configuration to allow only VPC traffic. You can verify that these commands have been executed successfully by running the command:
net.get_vpc_traffic_config
This command will show you the current settings of the virtual switch and the VPC east-west traffic configuration.
Third, you need to SSH directly to any AHV node (not a CVM) in the cluster and run the command:
ovs-vsctl show
This command will display an overview of the Open vSwitch configuration on the AHV node. You can copy and paste the output of this command to a new text file named Desktop\Files\Network\AHVswitch.txt.
You can use any SSH client such as PuTTY or Windows PowerShell to connect to the AHV node. You will need the IP address and the credentials of the AHV node, which you can find in Prism Element or Prism Central.

Here is the step-by-step solution to reconfigure the sql3532 virtual machine.
This task is performed from the Prism Element interface for the cluster the VM is on (e.g., Cluster 1).
1. Locate and Update the VM
* From the Prism Element main dashboard, navigate to the VM view.
* Find the VM named sql3532 in the VM table.
* Select the checkbox next to sql3532 and click the Update button.
2. Configure HA Priority and Flash Mode
In the "Update VM" dialog, configure the HA and SSD performance settings:
* HA Priority:
* Find the VM High Availability section.
* Select the High Priority radio button. This ensures it is one of the first VMs to power on during an HA event.
* Flash Mode (SSD Performance):
* Scroll down to the Flash Mode section.
* Check the box to Enable Flash Mode. This pins the VM's vDisks to the SSD tier, satisfying the requirement to keep as much of the VM as possible on SSDs, especially since it's on the default (hybrid) container.
3. Reconfigure Disks (per KB-3532)
While still in the "Update VM" dialog, scroll to the Disks section to add the new data and log disks. The key to "best performance" (KB-3532) is to place Data and Logs on separate vSCSI controllers.
* (The VM already has an OS disk, which we will assume is on scsi.0.)
* Add Data Disk:
* Click the + Add New Disk button.
* Storage Container: default (as required).
* Size: 80 GB (for the 4 x 20 GB databases).
* Bus Type: SCSI.
* Device Index: 1. (This creates a new vSCSI controller, scsi.1, for the data disk).
* Click Add.
* Add Log Disk:
* Click the + Add New Disk button.
* Storage Container: default (as required).
* Size: 20 GB.
* Bus Type: SCSI.
* Device Index: 2. (This creates a third vSCSI controller, scsi.2, for the log disk).
* Click Add.
4. Save Configuration
* After adding the disks and setting HA/Flash Mode, click the main Save button at the bottom of the
"Update VM" dialog.
The VM is now configured with high availability, its storage is pinned to SSD, and its disk layout follows performance best practices by separating the OS, Data, and Log I/O paths onto three different controllers.

Here is the step-by-step solution to correct the API payload and deploy the VM.
This task is performed using the REST API Explorer within Prism Central.
1. Get Required UUIDs
To create a VM, you first need the unique IDs (UUIDs) for the target cluster and network.
* From the Prism Central dashboard, click the question mark (?) icon in the top-right corner and select REST API Explorer.
* Find Cluster 1 UUID:
* In the API Explorer, search for and select the clusters/list (POST) endpoint.
* In the Body field, paste a simple filter: { "kind": "cluster" }
* Click Send.
* In the "Response" body, find the entry for Cluster 1 and copy its metadata.uuid value.
* Find default-net UUID:
* Search for and select the subnets/list (POST) endpoint.
* In the Body field, paste: { "kind": "subnet" }
* Click Send.
* In the "Response" body, find the entry where spec.name is default-net and copy its metadata.uuid value.
2. Correct the API Payload File
The error message "'metadata' is a required property" and "'spec' is a required property" indicates the JSON in the file is malformed and missing the required root-level objects. The file content also does not match the VM specifications.
* On the desktop, open API_Create_VM.txt in Notepad.
* Delete all existing text in the file (including the POST Call and Body: lines).
* Paste the following corrected and complete JSON payload into the file.
* Replace <UUID_for_Cluster_1> and <UUID_for_default-net> with the actual UUIDs you copied in the previous step.
JSON
{
"spec": {
"name": "API_VM_Task15",
"resources": {
"power_state": "OFF",
"num_sockets": 2,
"num_vcpus_per_socket": 1,
"memory_size_mib": 8192,
"disk_list": [
{
"disk_size_mib": 51200,
"device_properties": {
"device_type": "DISK"
}
}
],
"nic_list": [
{
"subnet_reference": {
"kind": "subnet",
"uuid": "<UUID_for_default-net>"
}
}
],
"guest_customization": {
"is_overridable": true,
"override_branding": true
}
},
"cluster_reference": {
"kind": "cluster",
"uuid": "<UUID_for_Cluster_1>"
}
},
"metadata": {
"kind": "vm"
}
}
* Save and close the API_Create_VM.txt file.
Correction Summary:
* JSON Structure: The original file was malformed. The new payload provides the required spec and metadata objects at the root level.
* vCPUs: Set to 2 sockets (2 vCPUs total).
* Memory: Set to 8192 MiB (8 GB).
* Disk: Set to 51200 MiB (50 GB) and removed the unneeded CDROM.
* Cluster/Network: Placeholders are added for the required UUIDs.
* Branding: guest_customization.override_branding: true is added to disable branding for the VM.
3. Deploy the VM via API
* Return to the REST API Explorer.
* Search for and select the vms (POST) endpoint (the one with the description "Create a new vm").
* Open the corrected API_Create_VM.txt file, copy its entire contents (which now includes your specific UUIDs).
* Paste the complete JSON payload into the Body field of the vms (POST) endpoint.
* Click Send.
The API will return a 202 Accepted response, and the VM will be created (and remain powered off) on Cluster 1.

Here is the step-by-step solution to configure syslog for Cluster 1.
1. Access Cluster 1 Prism Element
Since the requirement is to only configure Cluster 1 and not other clusters, this task must be performed in the Prism Element (PE) interface for Cluster 1.
* From the main Prism Central dashboard, navigate to Hardware > Clusters.
* Find Cluster 1 in the list and click its name. This will open the specific Prism Element login page for that cluster.
* Log in to Cluster 1's Prism Element interface.
2. Add the Syslog Server
* In the Cluster 1 PE interface, click the gear icon (Settings) in the top-right corner.
* From the left-hand menu, select Syslog.
* In the "Remote Syslog Server" section, click the + Add Syslog Server button.
* Fill in the server details as required:
* Name: Corp_Syslog
* IP Address: 34.142.155.231
* Port: 514
* Protocol: TCP (This provides the highest reliability, as requested).
* Click Save.
3. Configure Log Modules and Severities
Now, we must specify which logs to send to the new server.
* On the same Syslog settings page, find the "Syslog Configuration" section and click the Configure button (or Modify if a default is present).
* A dialog box "Select Modules and Levels" will appear.
* Uncheck all modules to ensure no extra logs are sent.
* Check the box for the RSyslog Server Module (or rsyslog_forwarder).
* For this module, check the boxes for the severities: Critical, Warning, and Info.
* Check the box for the ApiServer module.
* This module logs all operational tasks and audit trails, which includes all Virtual Machine changes.
* For this module, check the boxes for the top severity levels: Critical, Warning, and Info.
* Ensure no other modules (like Stargate, Cerebro, Zookeeper, etc.) are checked.
* Click Save.
Cluster 1 is now configured to send its audit logs (including VM changes) and its own syslog monitoring logs to the Corp_Syslog server via TCP, fulfilling all security requirements.
