What action should the consultant take to resolve this issue?
- A. Check jumbo frames support of the network switch.
- B. Enable queue depth on ports connected to nodes.
- C. Disable STP on ports connected to Nutanix nodes.

質問 # 105
An administrator is deploying a new application to a Nutanix Enterprise Cloud. The application requires a security to prevent unauthorized access. The application also uses many non-standard ports that are unique to it. Security should not be changed for existing applications.
What should the administrator do to meet these requirement?
- A. Use existing categories for the VMs. and create new security policies to use the existing categories.
- B. Create new categories for the VMs, and create new security policies that include the new categories.
- C. Use existing categories for the VMs and modify existing security policies to include the specific port.
- D. Create new categories for the VMs, and modify existing security policies to include the new categories.
正解：B
解説：
To ensure the new application is securely deployed without affecting existing applications, the administrator should create new categories for the VMs hosting the new application. This approach allows for targeted application of security policies without impacting other applications. After creating these new categories, the administrator should then create new security policies that incorporate these categories and specify the unique, non-standard ports used by the application, ensuring that security is tailored specifically to the new application's needs.References: Nutanix Prism Central Guide, Nutanix Security Configuration Best Practices.
質問 # 106
A customer already has a Prism Central (PC) instance deployed in their environment and expects the consultant to unregister the old cluster before registering the new cluster What steps should the consultant take to safely and successfully unregister the customer's former cluster from PC?
- A. Login to the PC Web UI, locate the PE cluster and click Unregister from the Actions dropdown menu.
- B. Login to any PCVM using SSH and run the PE_unreglster.py script located in the Nutanix scripts directory, followed by the unregistratlon_cleanup.py script
- C. Login to the PC Web Ul, navigate to Cluster Registrations found under settings in the Admin Center, check the box next to the desired PE. and click Remove
- D. Login to any CVM using SSH and use the multicluster command found within NCLi, followed by the unregistration_cleanup.py script on PE and PC.
正解：C
解説：
To safely and successfully unregister the customer's former cluster from Prism Central (PC), the consultant should take the following steps as outlined in option D:
* Login to the Prism Central Web UI, which provides a user-friendly interface for managing multiple clusters.
* Navigate to the "Cluster Registrations" section found under the "Settings" in the "Admin Center" of the Prism Central interface.
* Check the box next to the desired Prism Element (PE) cluster that needs to be unregistered.
* Click the "Remove" button to unregister the cluster.
This method allows the consultant to cleanly and directly manage the cluster registration without needing to interact with command-line tools or scripts, making it a straightforward process that minimizes the risk of errors and ensures that the operation can be tracked and audited through the UI.

質問 # 109
After a consultant runs a bare metal Foundation, the imaging process fails.
In which two locations can the consultant find the logs? (Choose two.)
- A. On the Foundation VM - /home/nutanix/foundation/logs
- B. On the CVM - /home /nutanix/foundation/logs
- C. View Logs link on the Foundation Imaging progress screen
- D. On the Hypervisor - /home/nutanix/foundation/logs
正解：A、C
解説：
After a failed bare metal Foundation imaging process, the consultant can find relevant logs in two primary locations: on the Foundation VM at "/home/nutanix/foundation/logs" and via the "View Logs" link available on the Foundation Imaging progress screen. These logs are crucial for diagnosing issues during the imaging process as they provide detailed error messages and operational data.References:

質問 # 110
After the migration, some SQL queries take longer to execute than prior to migration.
The following SQL best practices were applied while creating the SQL VM on Nutanix:
*8 vDisks per SQL server VM
*Database and Log files on separate vDisk
*2 TempDB database drives and 1 TempDB log drive
What should the administrator to do improve the SQL Server performance?
- A. Create multiple SQL log files and disable autogrowth
- B. Redistribute existing data by creating additional database file and enable autogrowth
- C. Redistribute existing data by creating additional database files and disable autogrowth
- D. Create multiple TempDB data files and enable autogrowth
正解：D
解説：
In the scenario where SQL queries are running slower post-migration, creating multiple TempDB data files is a recognized best practice for optimizing SQL Server performance, especially when dealing with high transaction rates or complex queries. This approach helps in distributing the I/O load across multiple files and drives, reducing the contention and wait times associated with TempDB, which is a common bottleneck in SQL Server environments. Enabling autogrowth ensures that these files can dynamically grow as needed, which helps in handling unexpected increases in database activity without manual intervention.References:
Nutanix Best Practices for SQL Server, SQL Server performance tuning guidelines.
質問 # 111
A consultant is planning to use a flat switch for installation.
What is the network requirement for Foundation VM, CVM, Hypervisor, and IPMI
- A. Foundation VM and CVM must be on the same subnet. Hypervisor and IPMI can be on a different subnet.
- B. Foundation VM, CVM, and IPMI must be on the same subnet. Hypervisor can be on a different subnet.
- C. CVM, Hypervisor, and IPMI must be on the same subnet. Foundation VM can be on a different subnet.
- D. Foundation VM, CVM, and Hypervisor must be on the same subnet. IPMI can be on a different subnet.
正解：D
解説：
In a typical Nutanix deployment using a flat switch, the Foundation VM, the CVM, and the Hypervisor should all be on the same subnet to facilitate seamless communication and management operations during the initial setup and operation. The IPMI, being a management interface, can be on a different subnet as it serves a different purpose primarily for remote management at the hardware level and does not need to be on the same subnet as the other components for cluster functionality.References:
* Nutanix University - NCS-Core 6.8 Learning Path
* The Nutanix Bible, Network Configuration chapter (https://www.nutanixbible.com/)
質問 # 112

- B. 32GB
- C. 24GB
- D. 20G?
正解：A
解説：

質問 # 113
When utilizing the Nutanix cluster As Built Document generator, which two configuration elements should a consultant provide when running the run_as_built.exe command? (Choose two.)
- A. Remote Site IP
- B. Customer Name
- C. Cluster IP
- D. Data Services IP
正解：B、C
解説：
When using the Nutanix cluster As Built Document generator, the necessary configuration elements to provide when running the run_as_built.exe command include the Cluster IP (B) and the Customer Name (D). The Cluster IP is required to properly identify and communicate with the cluster to gather configuration and operational data. The Customer Name is typically used to personalize the documentation, making it specific to the client's deployment, which is useful for record-keeping and future reference purposes.References: Nutanix As Built Documentation generator usage guidelines, Nutanix Best Practices for Documentation.
