Nutanix Certified Master - Multicloud Infrastructure (NCM-MCI) Sample Questions:
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.
Correct Answer:
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
Task 14
An administrator has been asked to configure a storage for a distributed application which uses large data sets across multiple worker VMs.
The worker VMs must run on every node. Data resilience is provided at the application level and low cost per GB is a Key Requirement.
Configure the storage on the cluster to meet these requirements. Any new object created should include the phrase Distributed_App in the name.
Correct Answer:
See the Explanation for step by step solution.
Explanation:
To configure the storage on the cluster for the distributed application, you can follow these steps:
Log in to Prism Element of cluster A using the credentials provided.
Go to Storage > Storage Pools and click on Create Storage Pool.
Enter a name for the new storage pool, such as Distributed_App_Storage_Pool, and select the disks to include in the pool. You can choose any combination of SSDs and HDDs, but for low cost per GB, you may prefer to use more HDDs than SSDs.
Click Save to create the storage pool.
Go to Storage > Containers and click on Create Container.
Enter a name for the new container, such as Distributed_App_Container, and select the storage pool that you just created, Distributed_App_Storage_Pool, as the source.
Under Advanced Settings, enable Erasure Coding and Compression to reduce the storage footprint of the data.
You can also disable Replication Factor since data resilience is provided at the application level. These settings will help you achieve low cost per GB for the container.
Click Save to create the container.
Go to Storage > Datastores and click on Create Datastore.
Enter a name for the new datastore, such as Distributed_App_Datastore, and select NFS as the datastore type.
Select the container that you just created, Distributed_App_Container, as the source.
Click Save to create the datastore.
The datastore will be automatically mounted on all nodes in the cluster. You can verify this by going to Storage > Datastores and clicking on Distributed_App_Datastore. You should see all nodes listed under Hosts.
You can now create or migrate your worker VMs to this datastore and run them on any node in the cluster.
The datastore will provide low cost per GB and high performance for your distributed application.

Due to new security requirements, an administrator has been tasked with updating the security settings for user accounts within Prism Element on Cluster 1.
An SSL Certificate Signing Request with Subject Alternative Name should be generated for submission to the security team's Certificate Authority with the following details:
countryName = US
stateOrProvinceName = North Carolina
localityName = Durham
organizationName = ACME
organizationalUnitName = Infrastructure
commonName = prism_element.ACME.org
emailAddress = [email protected]
Alternate names = cvm1.ACME.org, cvm2.ACME.org, cvm3.ACME.org
Encryption: RSA 2048, sha256
When the Certificate Signing Request is generated, place a copy of both the .cnf file and the .csr file on the desktop named 'prism_element_acme.cnf' and 'prism_element_acme.csr' Save a copy of the command(s) used for this scenario to a new file on the desktop named "Task 5.txt".
Note: You must copy and paste the command(s) and output from SSH to the "Task 5.txt" file to achieve all points available.
Correct Answer:
See the Explanation below for detailed answer.
Explanation:
Here is the step-by-step solution to generate the Certificate Signing Request (CSR) on Cluster 1.
This entire process is performed from an SSH session connected to a CVM (Controller VM) on Cluster 1.
1. Access Cluster 1 CVM
* From Prism Central, navigate to Hardware > Clusters and click on Cluster 1 to open its Prism Element (PE) interface.
* In the Cluster 1 PE, navigate to Hardware > CVMs to find the IP address of any CVM in the cluster.
* Use an SSH client (like PuTTY) to connect to the CVM's IP address.
* Log in with the admin user and password.
2. Create the Configuration File (.cnf)
To include the Subject Alternative Names (SANs), you must first create a configuration file.
* In the CVM's command line, create the .cnf file using a text editor:
vi prism_element_acme.cnf
* Press i to enter "Insert" mode.
* Paste the following text exactly into the editor:
Ini, TOML
[ req ]
default_bits = 2048
distinguished_name = req_distinguished_name
req_extensions = v3_req
prompt = no
[ req_distinguished_name ]
C = US
ST = North Carolina
L = Durham
O = ACME
OU = Infrastructure
CN = prism_element.ACME.org
emailAddress = [email protected]
[ v3_req ]
subjectAltName = @alt_names
[ alt_names ]
DNS.1 = cvm1.ACME.org
DNS.2 = cvm2.ACME.org
DNS.3 = cvm3.ACME.org
* Press Esc to exit "Insert" mode, then type :wq and press Enter to save and quit vi.
3. Generate the CSR and Key
* Run the following openssl command. This command uses the .cnf file to generate the new CSR (.csr) and a corresponding private key (.key), applying the sha256 encryption as requested.
Bash
openssl req -new -nodes -out prism_element_acme.csr -keyout prism_element_acme.key -config prism_element_acme.cnf -sha256
* The command will output the following, confirming the key generation:
* Generating a 2048 bit RSA private key
* ...................+++++
* ..................................+++++
* writing new private key to 'prism_element_acme.key'
* -----
4. Save Files to the Desktop
You will now copy the contents of the generated files from the CVM to your desktop.
* For Task 5.txt (Commands and Output):
* Open a new Notepad file on the desktop.
* Copy and paste all the commands you ran in the SSH session and their full output (as shown in steps 2 and 3) into this file.
* Save the file on the desktop as Task 5.txt.
* For prism_element_acme.cnf:
* In the CVM SSH session, display the file's content:
cat prism_element_acme.cnf
* Copy the entire text output (starting from [ req ]).
* Open a new Notepad file on the desktop.
* Paste the content and save the file as prism_element_acme.cnf.
* For prism_element_acme.csr:
* In the CVM SSH session, display the file's content:
cat prism_element_acme.csr
* Copy the entire text output, including the -----BEGIN CERTIFICATE REQUEST----- and ----- END CERTIFICATE REQUEST----- lines.
* Open a new C:\Users\admin\Desktop\Notepad file on the desktop.
* Paste the content and save the file as prism_element_acme.csr.
