質問 # 151
A consultant is working to setup the network before starting the Foundation process.
How should the consultant complete this task?
- A. Using the shared IPMI port, ensure that the connected switch can auto-negotiate to 1 Gbps.
- B. Disable IPv6 on the network to which the nodes are connected to ensure that IPv6 unicast is blocked.
- C. Ensure the IPMI of the nodes are reachable using pre-configured IPMI IPv6 addresses.
- D. On Nutanix NX Series, connect the IPMI port and any one of the data ports to the switch.
正解：D
解説：
Before starting the Foundation process, the consultant should prepare the network by:
* On Nutanix NX Series, connect the IPMI port and any one of the data ports to the switch: This ensures that the IPMI (for management and remote access) and at least one data port (for cluster communication and data traffic) are connected and operational, facilitating a smooth foundation process.

質問 # 153
A Nutanix cluster has 10TB usable storage. The customer wants to create a 100GB datastore for ISO images to eliminate too much storage being consumed by unnecessary images.
Which setting should be used to accomplish this goal?
- A. From Container Advanced Settings, configure 100GB for reserved capacity.
- B. From Container Advanced Settings, enable erasure coding.
- C. From Container Advanced Settings, turn on compression and deduplication.
- D. From Container Advanced Settings, configure 100GB for advertised capacity.
正解：D
解説：
To limit a datastore to a specific capacity within a Nutanix cluster, the best approach is to configure the advertised capacity in the Container Advanced Settings. Setting the advertised capacity to 100GB ensures that this amount of storage is reported to external entities (like hypervisors or operating systems) as the total usable capacity of the datastore, effectively preventing the storage of additional data beyond this limit. This method is preferred over reserving capacity, which guarantees space for specific uses but doesn't limit the total size visible to the system.

質問 # 154
The installation process stops before imaging any of the nodes and an error message is displayed notifying the IPMI IP address is unreachable.
What should consultant do to fix the issue?
- A. Re-try Foundation using a non-flat switch.
- B. if the nodes are in the same subnet go to the Cluster page and configure multi-homing.
- C. Ensure the Foundation VM is not in the same broadcast domain as the Controller VMs.
- D. Check the service. log and the individual node log files for more detailed information.
正解：D
解説：
When facing an error during the installation process that the IPMI IP address is unreachable:
* C. Check the service.log and the individual node log files for more detailed information: Reviewing these log files will provide insights into what might be causing the IPMI connectivity issue, offering specific error messages or network configuration problems that need resolution.

質問 # 155
An administrator responsible for a VDI environment needs to investigate reports of slow logins.
Theadministrator finds that increasing the number of vCPUs from 2 to 4 will reduce the login times.
Production workloads are consuming 75% of the host CPU on the cluster. The administrator increases the vCPU count on all of the VDI VMs.
What are two impacts on the cluster? (Choose two.)
- A. Increase CPU ready%
- B. Increase CPU utilization%
- C. Increase memory utilization%
- D. Increasing CPU counts will decrease memory utilization
正解：A、B
質問 # 156
A customer racks all nodes in the new cluster. The customer does not allow IPv6 for node discovery.
The consultant is not allowed to use the consultant's own flat switch in the customer's environment.
Which step should the consultant take to resolve this issue?
- A. Bare metal image all nodes with Foundation VM.
- B. Image each node individually with Foundation VM.
- C. Open a console to all nodes and statically assign IP addresses.
- D. Connect to the top of rack switch and discover the nodes with IPv4.
正解：D
解説：
In environments where IPv6 is not allowed for node discovery and the use of an external flat switch by the consultant is also restricted, the viable approach is to connect to the top of rack switch and discover the nodes using IPv4. This method aligns with the customer's networking policies and leverages the existing network infrastructure to facilitate the discovery and configuration of the nodes within the Nutanix cluster.References:
Nutanix Bible, Nutanix University NCS-Core 6.8 resources, and Nutanix official guidelines on node discovery using IPv4.
質問 # 157
A consultant needs to verify the make and model of the systems that will be imaged with Foundation. The consultant does not have the Bill of Materials (BOM) available to review.
When should the consultant verify the make and model to prepare for the cluster deployment?
- A. While conducting the Tech Review Call
- B. When reviewing the Statement of Work (SOW)
- C. During the Foundation Process
- D. Upon arriving on-site
正解：A
解説：
The make and model of the systems should be verified during the Tech Review Call. This step is essential to ensure that all necessary information is collected and verified before any physical interaction with the hardware. Verifying these details during the call helps in preparing adequately for the cluster deployment, allowing the consultant to anticipate and mitigate any compatibility or configuration issues before arriving onsite.References: Nutanix Foundation Guide, Pre-installation Checklist Documents.
質問 # 158
An administrator configure Active Directory (AD) authentication for their Nutanix environment. When login in using an AD user account, the login process takes more than one minute to complete. No delay occurs when logging a local account.
What should the administrator confirm to resolve this issue?
- A. The domain controller being used is configured as a global catalog server.
- B. The service Account Username is correct for the domain.
- C. Active directory lookups are configured to use Non-Recursive mode.
- D. The user search base for the group is configured correctly
正解：C
解説：
In a Nutanix environment, if the login process using an Active Directory (AD) user account takes more than a minute to complete, it could be due to the configuration of the AD lookups.
Active Directory lookups can be configured to use either Recursive or Non-Recursive mode. In Recursive mode, the system will look up each group that a user is a member of, then each group that those groups are members of, and so on. This can lead to a large number of lookups and potentially slow down the login process1.
On the other hand, in Non-Recursive mode, the system only looks up the direct groups that a user is a member of. This can significantly reduce the number of lookups and speed up the login process1.
Therefore, the administrator should confirm that Active Directory lookups are configured to use Non-Recursive mode to resolve this issue.

In which part of the Knowledge Transfer can the customer learn how to create, escalate, comment, and close cases?
- A. Demonstration of features
- B. Operations Guide
- C. Handover Slides and Checklist
- D. Demonstration of the Support Portal
正解：D
