Task 6
An administrator needs to assess performance gains provided by AHV Turbo at the guest level.
To perform the test the administrator created a Windows 10 VM named Turbo with the following configuration.
1 vCPU
8 GB RAM
SATA Controller
40 GB vDisk
The stress test application is multi-threaded capable, but the performance is not as expected with AHV Turbo enabled. Configure the VM to better leverage AHV Turbo.
Note: Do not power on the VM. Configure or prepare the VM for configuration as best you can without powering it on.
正解:
解説:
To configure the VM to better leverage AHV Turbo, you can follow these steps:
Log in to Prism Element of cluster A using the credentials provided.
Go to VM > Table and select the VM named Turbo.
Click on Update and go to Hardware tab.
Increase the number of vCPUs to match the number of multiqueues that you want to enable. For example, if you want to enable 8 multiqueues, set the vCPUs to 8. This will improve the performance of multi-threaded workloads by allowing them to use multiple processors.
Change the SCSI Controller type from SATA to VirtIO. This will enable the use of VirtIO drivers, which are required for AHV Turbo.
Click Save to apply the changes.
Power off the VM if it is running and mount the Nutanix VirtIO ISO image as a CD-ROM device. You can download the ISO image from Nutanix Portal.
Power on the VM and install the latest Nutanix VirtIO drivers for Windows 10. You can follow the instructions from Nutanix Support Portal.
After installing the drivers, power off the VM and unmount the Nutanix VirtIO ISO image.
Power on the VM and log in to Windows 10.
Open a command prompt as administrator and run the following command to enable multiqueue for the VirtIO NIC:
ethtool -L eth0 combined 8
Replace eth0 with the name of your network interface and 8 with the number of multiqueues that you want to enable. You can use ipconfig /all to find out your network interface name.
Restart the VM for the changes to take effect.
You have now configured the VM to better leverage AHV Turbo. You can run your stress test application again and observe the performance gains.

質問 # 25
The security team has provided some new security requirements for cluster level security on Cluster 2.
Security requirements:
* Update the password for the root user on the Cluster 2 node to match the admin user password.
Note: The 192.168.x.x network is not available. To access a node use the host IP (172.30.0.x) from the CVM.
* Output the cluster-wide configuration of the SCMA policy to desktop\output.txt before changes are made.
* Enable the Advanced Intrusion Detection Environment (AIDE) to run on a weekly basis for the hypervisor and cvms for Cluster 2.
* Enable high-strength password policies for the hypervisor and cluster.
* Ensure CVMs require SSH keys for login instead of passwords. (SSH keys are located in the desktop\Files\SSH folder.) Ensure the cluster meets these requirements. Do not reboot any cluster components.
Note: Please ensure you are modifying the correct components.
正解:
解説:
See the Explanation below for detailed answer.
Explanation:
Here is the step-by-step solution to apply the security requirements to Cluster 2.
1. Access Cluster 2 Prism Element
First, we must access the Prism Element (PE) interface for Cluster 2, as most security settings are cluster- specific.
* From the Prism Central dashboard, navigate to Hardware > Clusters.
* Find Cluster 2 in the list and click its name. This will open the Prism Element login page for that specific cluster in a new tab.
* Log in to Cluster 2's Prism Element using the admin credentials.
2. Requirement: Update Node Root Password
This task syncs the root password for all AHV hypervisor nodes with the cluster's admin user password.
* In the Cluster 2 PE interface, click the gear icon (Settings) in the top right corner.
* Select Cluster Lockdown from the left-hand menu.
* Click the Set Root Password on All Hosts button.
* A dialog box will appear. Enter the current admin password (the one you just used to log in) into both the New Password and Confirm New Password fields.
* Click Save. This will propagate the admin password to the root user on all nodes in Cluster 2.
3. Requirement: Add CVM SSH Key
This task adds the security team's public key to the admin user, which is required before we can disable password-based login.
* On the desktop, navigate to the Files > SSH folder.
* Open the id_rsa.pub file (or equivalent public key file) with Notepad.
* Copy the entire string of text (e.g., ssh-rsa AAAA...).
* In the Cluster 2 PE interface, go to Settings (gear icon) > User Management.
* Select the admin user and click Modify User.
* Paste the copied public key into the Public Keys text box.
* Click Save.
4. Requirement: Apply SCMA Policies (All other requirements)
The remaining requirements are all applied via the command line on a CVM using Nutanix's Security Configuration Management Automation (SCMA).
* Access the CVM:
* Find a CVM IP for Cluster 2 by going to Hardware > CVMs in the PE interface.
* Open an SSH client (like PuTTY) and connect to that CVM's IP address.
* Log in with the username admin and the corresponding password.
* Output Current Policy (Req 2):
* Before making changes, run the following command to see the current policy:
ncli scma status
* Copy the entire output from your SSH terminal.
* Open Notepad on the desktop, paste the copied text, and Save the file to the desktop as output.
txt.
* Apply New Policies (Req 3, 4, 5):
* Run the following commands one by one. The cluster will apply them immediately without a reboot.
* Enable AIDE (Req 3):
ncli scma update aide-status=enabled aide-schedule=weekly
* Enable High-Strength Passwords (Req 4):
ncli scma update password-policy=high
* Require SSH Keys for CVMs (Req 5):
ncli scma update ssh-login=keys-only
Verification
You can verify all changes by running the status command again. The output should now reflect the new, hardened security posture.
ncli scma status
* AIDE Status: should show Enabled
* AIDE Schedule: should show Weekly
* Password Policy: should show High
* SSH Login: should show keys-only
質問 # 26
The Database team is reporting performance degradation for a business-critical application on Saturdays.

正解:
解説:
See the Explanation below for detailed answer.
Explanation:
Here is the step-by-step solution to create the high-performance SQL VM on Cluster 1.
This task requires two phases: first, creating a new all-flash storage container, and second, creating the VM with a specific vNUMA and disk controller configuration for maximum performance.
1. Access Cluster 1 Prism Element
* 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. Create the All-Flash Storage Container
To maximize performance for a "write-intensive" workload on a hybrid cluster, the data and log disks must be placed on an all-flash container.
* In the Cluster 1 PE interface, click the gear icon (Settings) in the top-right corner.
* From the left-hand menu, select Storage.
* Click the + Storage Container button.
* Fill in the basic details:
* Name: NEWSQL_Flash_Container
* Click Advanced Settings.
* Scroll down to the Storage Tier section.
* Select the SSD radio button. This pins all data in this container to the SSD tier, ensuring all-flash performance.
* Click Save.
3. Create and Configure the VM
Now, create the VM, applying vNUMA and multi-SCSI controller best practices.
* From the main PE dashboard, navigate to the VM view.
* Click the + Create VM button.
* Enter the compute details. This configuration is critical for vNUMA performance, as it tells the VM's guest OS about the underlying physical NUMA topology (2 CPUs with 8 cores each).
* Name: NEWSQL_VM
* vCPUs: 12
* Number of Sockets: 2
* Cores per vCPU: 6 (This creates a 2-socket, 6-core VM, totaling 12 vCPUs)
* Memory: 128 GB
* Scroll down to the Disks section and add the OS disk:
* Click + Add New Disk.
* Storage Container: Select the default (hybrid) container.
* Size: 100 GB
* Bus: SCSI
* Device Index: 0 (This will be scsi.0)
* Click Add.
* Add the Data disk (on its own controller for parallel processing):
* Click + Add New Disk.
* Storage Container: Select NEWSQL_Flash_Container.
* Size: 750 GB
* Bus: SCSI
* Device Index: 1 (This creates a new controller, scsi.1)
* Click Add.
* Add a Log disk (on its own controller, a best practice for "write-intensive" SQL):
* Click + Add New Disk.
* Storage Container: Select NEWSQL_Flash_Container.
* Size: 100 GB (A common size for a log disk)
* Bus: SCSI
* Device Index: 2 (This creates a third controller, scsi.2)
* Click Add.
* Review the configuration: You should now have three disks attached, each on a separate controller (scsi.
0, scsi.1, scsi.2). This provides the maximum I/O performance.
* Ensure the Power on VM after creation box is unchecked.
* Click Save.
