  CORRECT TEXT

  Task 16

  Running NCC on a cluster prior to an upgrade results in the following output

  FAIL: CVM System Partition /home usage at 93% (greater than threshold, 90%) Identify the CVM with the issue, remove the fil causing the storage bloat, and check the health again by running the individual disk usage health check only on the problematic CVM do not run NCC health check

  Note: Make sure only the individual health check is executed from the affected node

  A. Answer: See the for step by step solution.

  Correct Answer: A

  To identify the CVM with the issue, remove the file causing the storage bloat, and check the health again, you can follow these steps:

  Log in to Prism Central and click on Entities on the left menu. Select Virtual Machines from the drop-down menu and find the NCC health check output file from the list. You can use the date and time information to locate the file. The file name

  should be something like ncc-output-YYYY-MM-DD-HH-MM-SS.log. Open the file and look for the line that says FAIL: CVM System Partition /home usage at 93% (greater than threshold, 90%). Note down the IP address of the CVM that has

  this issue. It should be something like X.X.X.X.

  Log in to the CVM using SSH or console with the username and password provided. Run the command du -sh /home/* to see the disk usage of each file and directory under /home. Identify the file that is taking up most of the space. It could

  be a log file, a backup file, or a temporary file. Make sure it is not a system file or a configuration file that is needed by the CVM.

  Run the command rm -f /home/ to remove the file causing the storage bloat. Replace with the actual name of the file. Run the command ncc health_checks hardware_checks disk_checks disk_usage_check -cvm_list=X.X.X.X to check the health again by running the individual disk usage health check only on the problematic CVM. Replace X.X.X.X with the IP address of the CVM that you noted down earlier.

  Verify that the output shows PASS: CVM System Partition /home usage at XX% (less than threshold, 90%). This means that the issue has been resolved.

• Question 3:

  CORRECT TEXT

  Task 11

  An administrator has noticed that after a host failure, the SQL03 VM was not powered back on from another host within the cluster. The Other SQL VMs (SQL01, SQL02) have recovered properly in the past.

  Resolve the issue and configure the environment to ensure any single host failure affects a minimal number os SQL VMs.

  Note: Do not power on any VMs

  A. Answer: See the for step by step solution.

  Correct Answer: A

  One possible reason why the SQL03 VM was not powered back on after a host failure is that the cluster was configured with the default (best effort) VM high availability mode, which does not guarantee the availability of VMs in case of

  insufficient resources on the remaining hosts. To resolve this issue, I suggest changing the VM high availability mode to guarantee (reserved segments), which reserves some memory on each host for failover of VMs from a failed host. This

  way, the SQL03 VM will have a higher chance of being restarted on another host in case of a host failure. To change the VM high availability mode to guarantee (reserved segments), you can follow these steps:

  Log in to Prism Central and select the cluster where the SQL VMs are running. Click on the gear icon on the top right corner and select Cluster Settings. Under Cluster Services, click on Virtual Machine High Availability. Select Guarantee

  (Reserved Segments) from the drop-down menu and click Save. To configure the environment to ensure any single host failure affects a minimal number of SQL VMs, I suggest using anti-affinity rules, which prevent VMs that belong to the

  same group from running on the same host. This way, if one host fails, only one SQL VM will be affected and the other SQL VMs will continue running on different hosts. To create an anti-affinity rule for the SQL VMs, you can follow these

  steps:

  Log in to Prism Central and click on Entities on the left menu. Select Virtual Machines from the drop-down menu and click on Create Group. Enter a name for the group, such as SQL Group, and click Next. Select the SQL VMs (SQL01,

  SQL02, SQL03) from the list and click Next. Select Anti-Affinity from the drop-down menu and click Next.

  Review the group details and click Finish.

  I hope this helps. How else can I help?

• Question 4:

  CORRECT TEXT

  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.

  First command

  #net.update_vpc_traffic_config virtual_switch=vs0

  net.update_vpc_traffic_config virtual_switch=vs1

  #net.update_vpc_east_west_traffic_config virtual_switch=vs0

  #net.update_vpc_east_west_traffic_config permit_all_traffic=false

  #net.update_vpc_east_west_traffic_config permit_vpc_traffic=false

  A. Answer: See the for step by step solution.

  Correct Answer: A

  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.

• Question 5:

  CORRECT TEXT

  Task 7

  An administrator has environment that will soon be upgraded to 6.5. In the meantime, they need to implement log and apply a security policy named Staging_Production, such that not VM in the Staging Environment can communicate with any

  VM in the production Environment,

  Configure the environment to satisfy this requirement.

  Note: All other configurations not indicated must be left at their default values.

  A. Answer: See the for step by step solution.

  Correct Answer: A

  To configure the environment to satisfy the requirement of implementing a security policy named Staging_Production, such that no VM in the Staging Environment can communicate with any VM in the production Environment, you need to do the following steps: Log in to Prism Central and go to Network > Security Policies > Create Security Policy. Enter Staging_Production as the name of the security policy and select Cluster A as the cluster. In the Scope section, select VMs as the entity type and add the VMs that belong to the Staging Environment and the Production Environment as the entities. You can use tags or categories to filter the VMs based on their environment. In the Rules section, create a new rule with the following settings: Direction: Bidirectional Protocol: Any Source: Staging Environment Destination: Production Environment Action: Deny Save the security policy and apply it to the cluster. This will create a security policy that will block any traffic between the VMs in the Staging Environment and the VMs in the Production Environment. You can verify that the security policy is working by trying to ping or access any VM in the Production Environment from any VM in the Staging Environment, or vice versa. You should not be able to do so.

  

• Question 6:

  CORRECT TEXT Task 3 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.

  A. Answer: See the for step by step solution.

  Correct Answer: A

  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 fromNutanix Portal. Power on the VM and install the latest Nutanix VirtIO drivers for Windows 10. You can

  follow the instructions fromNutanix 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

  Replaceeth0with the name of your network interface and8with the number of multiqueues that you want to enable. You can useipconfig /allto 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.

  Task 8

  Depending on the order you perform the exam items, the access information and credentials could change. Please refer to the other item performed on Cluster B if you have problems accessing the cluster.

  The infosec team has requested that audit logs for API Requests and replication capabilities be enabled for all clusters for the top 4 severity levels and pushed to their syslog system using highest reliability possible. They have requested no other logs to be included.

  Syslog configuration:

  Syslog Name: Corp_syslog

  Syslop IP: 34.69.43.123

  Port: 514

  Ensure the cluster is configured to meet these requirements.

  A. Answer: See the for step by step solution.

  Correct Answer: A

  To configure the cluster to meet the requirements of the infosec team, you need to do the following steps:

  Log in to Prism Central and go to Network > Syslog Servers > Configure Syslog Server. Enter Corp_syslog as the Server Name, 34.69.43.123 as the IP Address, and 514 as the Port. Select TCP as the Transport Protocol and enable RELP

  (Reliable Logging Protocol). This will create a syslog server with the highest reliability possible. Click Edit against Data Sources and select Cluster B as the cluster. Select API Requests and Replication as the data sources and set the log level

  to CRITICAL for both of them. This will enable audit logs for API requests and replication capabilities for the top 4 severity levels (EMERGENCY, ALERT, CRITICAL, and ERROR) and push them to the syslog server. Click Save.

  Repeat step 2 for any other clusters that you want to configure with the same requirements.

  

  

  To configure the Nutanix clusters to enable audit logs for API Requests and replication capabilities, and push them to the syslog system with the highest reliability possible, you can follow these steps:

  Log in to the Nutanix Prism web console using your administrator credentials. Navigate to the "Settings" section or the configuration settings interface within Prism. Locate the "Syslog Configuration" or "Logging" option and click on it.

  Configure the syslog settings as follows:

  Syslog Name: Enter "Corp_syslog" as the name for the syslog configuration. Syslog IP: Set the IP address to "34.69.43.123", which is the IP address of the syslog system.

  Port: Set the port to "514", which is the default port for syslog. Enable the option for highest reliability or persistent logging, if available. This ensures that logs are sent reliably and not lost in case of network interruptions.

  Save the syslog configuration.

  Enable Audit Logs for API Requests:

  In the Nutanix Prism web console, navigate to the "Cluster" section or the cluster management interface.

  Select the desired cluster where you want to enable audit logs. Locate the "Audit Configuration" or "Security Configuration" option and click on it. Look for the settings related to audit logs and API requests. Enable the audit logging feature and

  select the top 4 severity levels to be logged.

  Save the audit configuration.

  Enable Audit Logs for Replication Capabilities:

  In the Nutanix Prism web console, navigate to the "Cluster" section or the cluster management interface.

  Select the desired cluster where you want to enable audit logs. Locate the "Audit Configuration" or "Security Configuration" option and click on it. Look for the settings related to audit logs and replication capabilities. Enable the audit logging

  feature and select the top 4 severity levels to be logged.

  Save the audit configuration.

  After completing these steps, the Nutanix clusters will be configured to enable audit logs for API Requests and replication capabilities. The logs will be sent to the specified syslog system with the highest reliability possible.

  Task 9

  Part1

  An administrator logs into Prism Element and sees an alert stating the following:

  Cluster services down on Controller VM (35.197.75.196)

  Correct this issue in the least disruptive manner. Part2

  In a separate request, the security team has noticed a newly created cluster is reporting.

  CVM [35.197.75.196] is using thedefaultpassword.

  They have provided some new security requirements for cluster level security.

  Security requirements:

  Update the default password for the root user on the node to match the admin user password: Note: 192.168.x.x is not available. To access a node use the Host IP (172.30.0.x) from a CVM or the supplied external IP address.

  Update the default password for the nutanix user on the CVM to match the admin user password.

  Resolve the alert that is being reported.

  Output the cluster-wide configuration of the SCMA policy to Desktop\Files\output.txt before changes are made.

  Enable the Advance intrusion Detection Environment (AIDE) to run on a weekly basis for the cluster.

  Enable high-strength password policies for the cluster.

  Ensure CVMs require SSH keys for login instead of passwords. (SSH keys are located in the Desktop\Files\SSH folder).

  Ensure the clusters meets these requirements. Do not reboot any cluster components.

  A. Answer: See the for step by step solution.

  Correct Answer: A

  To correct the issue of cluster services down on Controller VM (35.197.75.196) in the least disruptive manner, you need to do the following steps:

  Log in to Prism Element using the admin user credentials. Go to the Alerts page and click on the alert to see more details. You will see which cluster services are down on the Controller VM. For example, it could be cassandra, curator,

  stargate, etc.

  To start the cluster services, you need to SSH to the Controller VM using the nutanix user credentials. You can use any SSH client such as PuTTY or Windows PowerShell to connect to the Controller VM. You will need the IP address and the

  password of the nutanix user, which you can find in Desktop\Files\SSH\nutanix.txt. Once you are logged in to the Controller VM, run the command:

  cluster status | grep -v UP

  This will show you which services are down on the Controller VM.

  To start the cluster services, run the command:

  cluster start

  This will start all the cluster services on the Controller VM. To verify that the cluster services are running, run the command:

  cluster status | grep -v UP

  This should show no output, indicating that all services are up. To clear the alert, go back to Prism Element and click on Resolve in the Alerts page. To meet the security requirements for cluster level security, you need to do the following

  steps:

  To update the default password for the root user on the node to match the admin user password, you need to SSH to the node using the root user credentials. You can use any SSH client such as PuTTY or Windows PowerShell to connect to

  the node. You will need the IP address and the password of the root user, which you can find in Desktop\Files\SSH\root.txt.

  Once you are logged in to the node, run the command:

  passwd

  This will prompt you to enter a new password for the root user. Enter the same password as the admin user, which you can find in Desktop\Files\SSH\admin.txt. To update the default password for the nutanix user on the CVM to match the

  admin user password, you need to SSH to the CVM using the nutanix user credentials. You can use any SSH client such as PuTTY or Windows PowerShell to connect to the CVM. You will need the IP address and the password of the nutanix

  user, which you can find in Desktop\Files\SSH\nutanix.txt.

  Once you are logged in to the CVM, run the command:

  passwd

  This will prompt you to enter a new password for the nutanix user. Enter the same password as the admin user, which you can find in Desktop\Files\SSH\admin.txt. To resolve the alert that is being reported, go back to Prism Element and click

  on Resolve in the Alerts page.

  To output the cluster-wide configuration of SCMA policy to Desktop\Files\output.txt before changes are made, you need to log in to Prism Element using the admin user credentials. Go to Security > SCMA Policy and click on View Policy

  Details. This will show you the current settings of SCMA policy for each entity type. Copy and paste these settings into a new text file named Desktop\Files\output.txt. To enable AIDE (Advanced Intrusion Detection Environment) to run on a

  weekly basis for the cluster, you need to log in to Prism Element using the admin user credentials. Go to Security > AIDE Configuration and click on Enable AIDE. This will enable AIDE to monitor file system changes on all CVMs and nodes in

  the cluster. Select Weekly as the frequency of AIDE scans and click Save. To enable high-strength password policies for the cluster, you need to log in to Prism Element using the admin user credentials.

  Go to Security > Password Policy and click on Edit Policy. This will allow you to modify the password policy settings for each entity type.

  For each entity type (Admin User, Console User, CVM User, and Host User), select High Strength as the password policy level and click Save. To ensure CVMs require SSH keys for login instead of passwords, you need to log in to Prism

  Element using the admin user credentials.

  Go to Security > Cluster Lockdown and click on Configure Lockdown. This will allow you to manage SSH access settings for the cluster.

  Uncheck Enable Remote Login with Password. This will disable password-based SSH access to the cluster.

  Click New Public Key and enter a name for the key and paste the public key value from Desktop\Files\SSH\id_rsa.pub. This will add a public key for key-based SSH access to the cluster.

  Click Save and Apply Lockdown. This will apply the changes and ensure CVMs require SSH keys for login instead of passwords.

  Part1

  Enter CVM ssh and execute:

  cluster status | grep -v UP

  cluster start

  If there are issues starting some services, check the following:

  Check if the node is in maintenance mode by running the ncli host ls command on the CVM. Verify if the parameter Under Maintenance Mode is set to False for the node where the services are down. If the parameter Under Maintenance

  Mode is set to True, remove the node from maintenance mode by running the following command:

  nutanix@cvm$ ncli host edit id= enable-maintenance-mode=false

  You can determine the host ID by usingncli host ls. See the troubleshooting topics related to failed cluster services in the Advanced Administration Guide available from the Nutanix Portal'sSoftware Documentationpage. (Use the filters to

  search for the guide for your AOS version). These topics have information about common and AOS-specific logs, such as Stargate, Cassandra, and other modules.

  Check for any latest FATALs for the service that is down. The following command prints all the FATALs for a CVM. Run this command on all CVMs. nutanix@cvm$ for i in `svmips`; do echo "CVM: $i"; ssh $i "ls -ltr /home/nutanix/data/logs/
