NEW QUESTION # 175
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. Increase CPU utilization%
- B. Increasing CPU counts will decrease memory utilization
- C. Increase CPU ready%
- D. Increase memory utilization%
Answer: A,C
Explanation:
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.

* The conclusions above are based on general virtualization principles covered in resources like the Nutanix Bible (https://www.nutanixbible.com/) and the Nutanix University training materials for NCS-Core certification (https://university.nutanix.com/). These sources explain the impact of CPU allocation and utilization in detail, particularly in the context of cluster performance and virtual desktop infrastructure.
* Additionally, practical insights into these dynamics are discussed in various video tutorials from the Nutanix official YouTube playlist for NCS-Core learning (https://www.youtube.com/playlist?list=PLAHgaS9IrJecs_AcQT3Y7vSsKT2mjz3Iu), which provide visual and step-by-step breakdowns of how CPU resources are managed in a Nutanix environment.
NEW QUESTION # 176
An organization subscribes to field advisories from the Nutanix support portal. An administrator receives an email about a rare problem that could cause cluster instability and affect the entire AOS cluster. The organization is running Vmware vsphere 6.x on Nutanix.
What action should be taken to resolve this issue?
- A. Open Prism Element and select Upgrade Software to update AOS.
- B. Use VMware Update Manager to update the cluster.
- C. File a ticket to Nutanix Support and provide the Field Advisory ID.
- D. In Prism Central, select Life Cycle Management and perform LCM update.
Answer: A
Explanation:
When receiving a field advisory from Nutanix support regarding a rare problem that could destabilize the cluster, the recommended action is to update AOS. This can be done via Prism Element by selecting "Upgrade Software." This method ensures that any patches or updates that address the identified issue are applied directly to the AOS environment, mitigating any potential risks associated with the reported problem. Since the organization uses VMware vSphere, the update specifically targets the AOS to ensure the underlying infrastructure supporting vSphere remains stable.References: Nutanix Support Portal, Nutanix Field Advisories, Prism Element Guide.

NEW QUESTION # 179
A customer has engaged a Nutanix consultant to deploy a cluster consisting of two NX-3460-G6 blocks. The consultant arrives at the customer site and fines the following:
* One rack with a total of 5U available
* Two ToR switches with 14 total available ports
* Dual PDUs with six available sockets
What will prevent the consultant from successfully installing the cluster?
- A. Insufficient network ports for communication.
Insufficient sockets for power allocation. - B. Insufficient network ports for communication.
Insufficient sockets for power allocation. - C. Insufficient sockets for power allocation.
Rack space may not be continuous. - D. Insufficient network ports for communication.
Rack space may not be continuous. - E. Insufficient rack space for block installation.
Insufficient sockets for power allocation.
Answer: E
Explanation:
To determine the correct answer, you must evaluate the requirements for installing a Nutanix NX-3460-G6 block. Each block typically occupies 2U of rack space. Since the customer has two blocks, a total of 4U is required, which fits within the available 5U rack space. Additionally, each block requires two power sockets (one for each node in the block), totaling four sockets. Since there are six available sockets, there is enough power availability. Therefore, the primary constraints are adequately met in terms of rack space and power sockets. The mention of network ports and their sufficiency is not required here, as it isn't the limiting factor based on the details provided.

NEW QUESTION # 183
A consultant creates a Nutanix cluster using the 10.10.10.0/24 network and VLAN 10. The customer creates a VM network inside the Prism using VLAN 20. The customer starts to create VMs but is unable to ping the default gateway from these new systems.
What is causing the issue?
- A. The CVM/hypervisor must be on an untagged VLAN.
- B. The CVM/hypervisor cannot use the same VLAN as guest VMs.
- C. The switch port is not set up as a trunk.
- D. Only one VLAN is supported on AHV.
Answer: C
Explanation:
The issue of VMs not being able to ping the default gateway from a newly created VM network on VLAN 20, while the Nutanix cluster uses VLAN 10, most likely stems from the switch port configuration. For the VMs on VLAN 20 to communicate outside their local network, the switch port to which the Nutanix nodes are connected must be configured as a trunk. This configuration allows multiple VLANs to coexist on the same physical port and enables routing between them. Without the trunk setup, the VLAN 20 traffic is restricted and cannot reach the network beyond the switch, including the default gateway.References: Nutanix Network Configuration Guide, Best Practices for VLAN Configurations.SZXCDESX
NEW QUESTION # 184
During a six-node cluster deployment, one node fails to image successfully and Foundation is unable to automatically configure the cluster. The consultant decides to manually complete cluster formation with the successful nodes, then expand the cluster with the remaining unconfigured node.
Which command should be used to begin the process?
- A. cluster status
- B. cluster expand
- C. cluster start
- D. cluster create
Answer: D
Explanation:
When deploying a multi-node Nutanix cluster, if one node fails to image and the Nutanix Foundation tool cannot configure the cluster automatically, the consultant can manually create the cluster with the nodes that were successfully imaged. The correct command to initiate this process is cluster create. This command starts the cluster services and allows for further expansion once the cluster is operational, which would include adding the node that initially failed to image.

Which step should the administrator use to initiate the project?
- A. Enable Jumbo Frames to accommodate network frames
- B. Convert storage only nodes into vSphere nodes
- C. Enable Nutanix Flow at the Prism Central Level
- D. Manually disable CVM network Segmentation
Answer: A
NEW QUESTION # 186
A consultant has been tasked with increasing security on a Nutanix cluster by disabling password authentication when accessing the CVM and AHV hosts and instead moving to key-based SSH.
What is the easiest way for the consultant to meet these requirements?
- A. Configure LDAP authentication through a secure server.
- B. Enable Cluster Lockdown and provide an RSA key.
- C. Enable STlGs via command line on SSH to a CVM.
- D. Restrict access with User Management in Prism.
Answer: B
Explanation:
The most straightforward approach for increasing security by disabling password authentication and moving to key-based SSH on a Nutanix cluster involves:
* C. Enable Cluster Lockdown and provide an RSA key: Cluster Lockdown mode restricts management access to the cluster, ensuring that only key-based SSH authentication is used to access the CVM and AHV hosts, enhancing security by eliminating the use of passwords.

NEW QUESTION # 188
A consultant finishes creating a new ESXi cluster. The consultant connects to the nodes via laptop and a personal flat switch. The host/CVM network is on VLAN 23. The customer has the native VLAN on the ToR switches set to 23.
The customer wants to use LACP. Before placing the nodes on the customer network, the consultant tags VLAN 23 for each host and CVM. The consultant connects the nodes to the customer network and finds that they are unreachable.
What is causing this issue?
- A. The hosts have not been migrated to a vSphere Distributed Switch.
- B. The customer has LACP fallback enabled on switch ports.
- C. Under the vSwitch0 settings, the consultant did not select Route based on IP hash.
- D. The host and CVM are incorrectly configured.
Answer: C
Explanation:
In this scenario, the connectivity issue arises because the VLAN settings require a specific configuration on the vSwitch settings when using LACP. When using LACP for load balancing network traffic, the vSwitch or Distributed Switch must be configured with the "Route based on IP hash" load balancing algorithm. This setting is necessary to properly distribute the traffic across the LACP bonded links. Not selecting this setting in vSwitch0 settings would result in improper handling of network packets over the LACP bonded links, thereby causing the hosts and CVMs to be unreachable. Adjusting the vSwitch settings to "Route based on IP hash" should resolve the connectivity issue.References: VMware vSphere Networking documentation, Nutanix Bible LACP configuration guidelines.
NEW QUESTION # 189
During a Site Readiness Check, a customer informed the consultant that there is no NTP server currently configured in the environment.
Which two statements should the consultant consider for continuing the cluster deployment? (Choose two.)
- A. If an NTP server is provided using FQDN, a DNS server is required.
- B. At least one external NTP server must be used to complete Foundation process.
- C. An NTP server is not required for cluster Foundation and can be added later.
- D. At least 3 NTP servers must be provided in a comma-separated list.
Answer: A,C
Explanation:
For continuing the cluster deployment without an NTP server immediately available: A. An NTP server is not required for the initial foundation process of the cluster and can indeed be added later. This allows the deployment to proceed without delays, although it's critical to add NTP synchronization as soon as possible post-deployment to ensure proper cluster time management. B. If an NTP server is to be provided using an FQDN, then a DNS server must indeed be available. This is because the FQDN needs to be resolved to an IP address, which requires DNS resolution services. Options C and D are not strictly required as per Nutanix deployment standards; a single NTP server can suffice initially, and there's no requirement for it to be external or in a comma-separated list unless specifically dictated by network or organizational policies.References:
Nutanix Installation and Configuration Guide, Nutanix Foundation Tool documentation.
