質問 # 90
A consultant creates three storage containers (container-1, container-2, container-3). The customer requires that only container-1, which will be utilized as an NFS datastore, be presented to external hosts.
However, users are able to mount all three containers.
What is causing this problem?
- A. A Container-level whitelist entry was configured.
- B. A Global whitelist entry was configured.
- C. Compression was turned on for all containers.
- D. Deduplication was turned on for all containers.
正解：B
解説：
The issue where users can mount all three storage containers despite the intention to restrict access to just container-1 typically stems from a Global whitelist entry. A global whitelist allows all entities to access all containers unless more specific restrictions are applied at the container level. To correct this, specific whitelist entries need to be configured for each container to define and restrict access appropriately.References: Nutanix NCS-Core 6.8 training resources, the Nutanix Bible, and Nutanix technical documentation on storage container management.

質問 # 93
An administrator responsible for a VDI environment needs to investigate reports of slow logins. The administrator 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. Increasing CPU counts will decrease memory utilization
- B. Increase CPU ready%
- C. Increase CPU utilization%
- D. Increase memory utilization%
正解：B、C
解説：
Increasing the number of vCPUs from 2 to 4 can indeed reduce login times by providing more processing power to handle the login requests. However, this action will have two main impacts on the cluster:
A: Increase CPU utilization%: By increasing the number of vCPUs, you are effectively increasing the demand for CPU resources. This will result in a higher percentage of the CPU being utilized.
B: Increase CPU ready%: CPU Ready is a measure of the amount of time a virtual machine is ready to run against the pCPU, but is waiting to be scheduled on the physical CPU. By increasing the number of vCPUs, you are increasing the number of virtual machines that are ready to run, which can increase the CPU Ready percentage.
Increasing the vCPU count does not directly affect memory utilization, so options C and D are not correct.

質問 # 101
Refer to the exhibit.
An administrator has an existing cluster and needs to improve performance using AHV Turbo. Which two items are required to achieve even greater performance? (Choose two.)
- A. VMs have one vCPU configured.
- B. VMs have multi-queue disabled.
- C. Workloads are multi-threaded.
- D. VMs have more than one vCPU.
正解：C、D
解説：
To maximize the performance benefits of AHV Turbo, which is designed to optimize network and storage I/O operations for VMs, certain VM configurations are advantageous. The correct answers are:
Option A, "Workloads are multi-threaded." Multi-threaded applications can better utilize the improvements in I/O processing efficiency provided by AHV Turbo, leading to better overall performance.
Option D, "VMs have more than one vCPU." This configuration allows VMs to handle multiple processes or threads simultaneously, which is particularly beneficial when combined with AHV Turbo's enhanced I/O operations.
References:The benefits of configuring VMs with multiple vCPUs and supporting multi-threaded applications are discussed in Nutanix's documentation on AHV and performance optimization, where AHV Turbo is highlighted for its ability to accelerate VM operations in a Nutanix environment.
質問 # 102
A customer wants to expand an existing cluster with three additional nodes. After running the Foundation process on the new nodes, the customer realizes that the wrong IPs where used and the nodes are configured on a different network. The customer decides to create a new cluster instead.
Which method should be used to recreate the cluster?
- A. Log into Hypervisor and use cluster create command to create the cluster.
- B. Log into IPMI and use cluster create command to create the cluster.
- C. Log into CVM and use cluster create command to create the cluster.
- D. Foundation all nodes again and create the cluster.
正解：D
解説：
When nodes are mistakenly configured with incorrect IP addresses and are on a different network, the most effective way to address this is to re-run the Foundation process. By using Foundation, the nodes can be completely re-imaged with the correct network settings and then properly integrated into a new cluster. This ensures that all hardware and software configurations align with the intended network and cluster settings, avoiding potential conflicts and issues that might arise from manual adjustments.

質問 # 103
A customer recently set up Async Replication between Site A and Site B. The customer wants to conduct a planned failover and clicks Activate on Site B.
The customer then runs the following command on Site A:
ncli pd deactivate_and__destroy_vms name=<protection_domain_name>
What does this do to the customer environment?
- A. Customer must then manually power off VMs at Site A and power them on at Site B.
- B. VMs are powered off on Site A and must be manually powered on at Site B.
- C. VMs get deleted from Site A and the protection domain is no longer active.
- D. VMs get deleted from Site B. and the protection domain is now Active.
正解：C
解説：
https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v5_10:wc-protection-do
The command ncli pd deactivate_and__destroy_vms name=<protection_domain_name> is a critical operation in managing Nutanix environments, particularly in scenarios involving disaster recovery and replication.
* This command deactivates the protection domain and deletes all VMs associated with that protection domain from the source site (Site A in this case). This operation is generally part of a planned migration or failover process where the VMs are intended to be run from the remote site (Site B).
* After this operation, the protection domain at Site A is no longer active, meaning it has been effectively removed along with its associated VMs, thus clearing the way for Site B to take over operations without conflict from the original site.
References:This action and its implications are covered under Nutanix disaster recovery and high availability strategies, detailed in both the Nutanix Bible and official Nutanix NCS-Core training materials, which discuss the management of protection domains and replication processes.

質問 # 106
A customer's security team has a policy prohibiting a consultant's laptop from connecting within the corporate datacenter.
In which two ways should the consultant complete the customer deployment on the factory-prepared nodes?
(Choose two.)
- A. Run the Network Crashcart Script, provide IPs, and create the cluster manually.
- B. Use the Controller VM-based Foundation process.
- C. Configure IPs on hosts and create the cluster.
- D. Manually edit ifcfg-etho file on CVM, restart networking, and create the cluster.
正解：A、B
解説：
Given that the customer's security policy prohibits connecting a consultant's laptop within the corporate datacenter, the consultant can complete the deployment using: A. The Controller VM-based Foundation process, which allows the consultant to configure and deploy the cluster using the software tools provided within the Controller VM itself. This method does not require direct laptop connection to the network. C. Run the Network Crashcart Script to manually configure IP addresses on the hosts and then proceed to create the cluster manually. This approach involves using available scripts and utilities that can be executed from within the data center's management interfaces without needing direct laptop access. Options B and D would typically require direct network connection capabilities not permissible under the security constraints.References:
Nutanix Foundation Documentation, Nutanix Deployment Best Practices.
質問 # 107
How should a consultant verify that a Nutanix cluster can tolerate a single-node failure?
- A. [root@cvm~]# ncli cluster get-domain-fault-tolerance-status
type=node - B. [root@avh~]# ncli cluster fault-tolerance-status type=node
- C. nutanix@cvm~$ ncli cluster status type=node
- D. nutanix@cvm~$ ncli cluster get-domain-fault-tolerance-status
type=node
正解：D
解説：
To verify that a Nutanix cluster can tolerate a single-node failure, the consultant should use the command nutanix@cvm~$ ncli cluster get-domain-fault-tolerance-status type=node. This command is executed from the Controller Virtual Machine (CVM) and checks the cluster's fault tolerance status specifically for node failures, providing insights into how the cluster's data resiliency and redundancy configurations are holding up against potential single-node failures.References: Nutanix CLI Guide, Nutanix Fault Tolerance Documentation.
