NCM-MCI試験無料問題集「Nutanix Certified Master - Multicloud Infrastructure v6.10 認定」
Refer to the exhibit.
Task1
A newly created Windows VM "SQL02" is experiencing poor storage performance when compared to "SQL01" running within the same cluster, on the same storage container.
The cluster is in a healthy state.
Create a new session named Monitor SQL02 with meaningful metrics. Right click on the session page and click Select All then paste this into Notepad and save it as Task 1.txt on the desktop.
Also, save the analysis as a report named "MonitorSQL02" and send the report as a PDF on a daily basis to [email protected]. Reports should not be retained. If any new objects need to be created, use monitorvm2 in the name.
Finally, correct the issue within "SQL02"
Notes:
Do not power on the VMs.
While you will be creating a session, you will need to examine the VM configurations to determine the issue.
Do not delete the VM to resolve the issue, any other destructive change is acceptable

See the Explanation
Explanation:
This is a classic Nutanix performance troubleshooting scenario. The issue is almost certainly that the VM was created using the wrong Disk Bus Type (IDE or SATA instead of SCSI).
Here is the step-by-step solution to complete Task 1.
Part 1: Analysis and Reporting
Create the Session
Log in to Prism Central (or Prism Element, depending on the exam environment, but Analysis is usually a PC feature).
Navigate to Operations -> Analysis.
Click New Session.
Name: Monitor SQL02
Entity: Search for and select the VM named SQL02.
Metrics: Since the issue is storage performance, search for and add these specific metrics:
Hypervisor IOPS (or Controller IOPS)
Hypervisor IO Latency (or Controller IO Latency)
Hypervisor IO Bandwidth
Click Save.
Save Session Data (Task 1.txt)
Open the "Monitor SQL02" session you just created.
(Per instructions): Right-click anywhere on the chart/data area -> Click Select All.
Copy the selected text (Ctrl+C).
Open Notepad on the provided desktop.
Paste the data.
Save the file as Task 1.txt on the Desktop.
Create and Schedule the Report
While still in the Analysis session, click the Create Report (or "Add to Report") button.
Report Name: MonitorSQL02
Report Settings:
Format: PDF
Frequency: Daily
Email Recipient: [email protected]
Retention: 0 (or "Do not retain", as requested).
Note: If the system forces you to create a new Report object and MonitorSQL02 is rejected, use monitorvm2 as the name per the instructions.
Save/Schedule the report.
Part 2: Diagnose and Fix the Issue
The Issue:
VM SQL02 was likely created with its data disks set to IDE or SATA.
Why this causes poor performance: IDE/SATA are emulated hardware with high CPU overhead and low queue depths (single-threaded).
The Standard: SQL01 (the healthy VM) is using SCSI, which is multithreaded and optimized for virtualization.
The Fix (Steps):
Navigate to the VM list in Prism.
Select SQL02 and click Update (or Edit).
Scroll down to the Disks section.
Identify the data disk(s). You will see the Bus Type listed as IDE or SATA.
Do not delete the VM. instead, perform a disk conversion (destructive change to the disk is allowed, but we want to keep the data).
Method to Convert (Clone to SCSI):
Hover over the IDE/SATA disk to see the path/filename of the vDisk (or write it down).
Click Add New Disk.
Operation: select Clone from ADSF file.
Path: Browse to the storage container and select the file associated with the current IDE disk.
Bus Type: Select SCSI (This is the critical fix).
Index: Ensure it doesn't conflict with existing disks (usually index 1 or higher for data).
Click Add.
Once the new SCSI disk is added, find the original IDE/SATA disk and click the X to remove it.
Click Save.
Note: You do not need to power on the VM to verify. The change from IDE to SCSI allows the VM to use the Nutanix VirtIO drivers for maximum storage performance.

Task4
An administrator will be deploying Flow Networking and needs to validate that the environment, specifically switch vs1, is appropriately configured. Only VPC traffic should be carried by the switch.
Four versions each of two possible commands have been placed in Desktop\Files\Network\flow.txt. Remove the hash mark (#) from the front of correct First command and correct Second command and save the file.
Only one hash mark should be removed from each section. Do not delete or copy lines, do not add additional lines. Any changes other than removing two hash marks (#) will result in no credit.
Also, SSH directly to any AHV node (not a CVM) in the cluster and from the command line display an overview of the Open vSwitch configuration. Copy and paste this to a new text file named Desktop\Files\Network\AHVswitch.txt.
Note: You will not be able to use the 192.168.5.0 network in this environment.

Explanation:
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.
remove # from greens
On AHV execute:
sudo ovs-vsctl show
CVM access AHV access command
nutanix@NTNX-A-CVM:192.168.10.5:~$ ssh [email protected] "ovs-vsctl show" Open AHVswitch.txt and copy paste output
