Task 11
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
Answer:
Explanation:
See the Explanation for step by step solution.
Explanation:
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/<filename> to remove the file causing the storage bloat. Replace <filename> 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.

NEW QUESTION # 31
The Infosec team has requested that all operational tasks performed within Cluster 1 be properly logged to include the top 4 severity levels and pushed to their syslog system using highest reliability possible for analysis. This is to include any Virtual Machine changes only.
The Infosec team has also requested that monitor logs for the given RSyslog Server Module be included for now. No extra logs should be included.
No other clusters should connect to this syslog server.
Syslog configuration:
* Syslog Name: Corp_Syslog
* Syslog IP: 34.142.155.231
* Port: TCP/514
Ensure only Cluster 1 is configured to meet these requirements.
Answer:
Explanation:
See the Explanation below for detailed answer.
Explanation:
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.

NEW QUESTION # 32
The DB team is requesting an SQL database instance and has requested it be configured for best performance.
This VM has been migrated from a 3 tier solution into Nutanix.
The database VM hosts 4 databases, each set to a 20 GB limit. Logs are expected to not grow beyond 20 GB and should be limited to within 25% to avoid runaway processes. Do not configure more storage than is needed.
The VM that has been migrated is identified as sql3532. Once the VM has been properly reconfigured, the DBA team will reconfigure the OS and database.
The VM should be configured as per KB-3532.
While this VM is being tested, make sure it is the first VM to power up in the event the node it is on goes down.
To maximize performance, ensure as much of the VM as possible will be kept on SSD drives.
Note: The VM does not need to be powered on. The VM should remain on the default container and should not be configured with a volume group. No network is required at this time.
Answer:
Explanation:
See the Explanation below for detailed answer.
Explanation:
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.
