The administrator can select the check name, such as disk_usage_check, and click on Edit Schedule. The administrator can then choose the desired frequency, such as every 15 minutes, every hour, or every day, and click on Save. This will change how often the check runs and alerts are generated.
質問 # 98
An administrator is tasked with configuring networking on an AHV cluster and needs to optimize for maximum single VM throughput.
Which bond mode should the administrator select?
- A. Active-Active
- B. Active-Active with Mac pinning
- C. Active-Backup
- D. No Uplink Bond
正解：A
解説：
Active-Active is a bond mode that allows all uplinks in the bond to be used simultaneously for traffic transmission and reception. This bond mode provides load balancing and increased bandwidth for the AHV host and its VMs. Active-Active bond mode uses a hashing algorithm based on source MAC addresses to distribute traffic across different uplinks in the bond. Each individual VM NIC uses only a single bond member interface at a time, but multiple VM NICs are spread across different bond member interfaces. As a result, it is possible for a Nutanix AHV node with two 10 Gb interfaces to use up to 20 Gbps of network throughput, while individual VMs have a maximum throughput of 10 Gbps6.
Therefore, if an administrator needs to optimize for maximum single VM throughput, they should select Active-Active bond mode for their AHV cluster. This bond mode can be configured using Prism Element UI or manage-ovs commands on each AHV host7. No additional configuration is required on the upstream switch side, as long as the switches are interconnected physically or virtually and both uplinks trunk the same VLANs8.
質問 # 99
Which component can be associated with a storage policy?
- A. Vm
- B. Category
- C. Subnet
- D. Catalog
正解：A
解説：
A storage policy can be associated with a VM. A storage policy is a set of rules that define how data objects are stored and protected. It specifies the characteristics of storage, data protection, and data placement for virtual disks that are assigned to a VM. Subnets, catalogs, and categories are not associated with storage policies.https://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-vpc_2022_6:mul-cluster-storage-policy-summary-view-pc-r.html
質問 # 100
An administrator needs to configure Prism to send encrypted messages to a set of recipients.
Which setting must be applied?
- A. Install SSL certificates on Prism Central
- B. Configure Prism Central to use Cluster Lockdown
- C. Use SMTP Port 25
- D. Set SMTP Security Mode to STARTTLS
正解：D
解説：
The best way for the administrator to configure Prism to send encrypted messages to a set of recipients is to set the SMTP Security Mode to STARTTLS. This will ensure that all messages sent over SMTP are encrypted and secure. Additionally, the administrator should consider installing SSL certificates on Prism Central to ensure that the messages are being sent securely. Finally, the administrator should consider configuring Prism Central to use Cluster Lockdown, which will help ensure that the messages are only sent to the intended recipients.
質問 # 101
An administrator has created a Nutanix managed it a VLAN ID of 512.
Several VMs have been created, and the administrator notices that the can successfully communicate with other VMs on that VLAN.
Provided they are on the host, but cannot communicate with VMs that reside on different hosts in the cluster.
What is most likely thee cause of this issue?
- A. VLANS12 is a reserved VLAN ID, and not usable for guest VMs.
- B. The VLAN was not created on the upstream switches.
- C. There is a firewall rule blockingVLAN512 traffic.
- D. The administrator did not create the VLAN on all hosts
正解：B
解説：
The correct answer is C. The VLAN was not created on the upstream switches.
A VLAN (virtual local area network) is a logical segmentation of a physical network that allows devices on the same VLAN to communicate with each other, regardless of their physical location. A VLAN also isolates the devices on different VLANs from each other, unless there is a router or a layer 3 switch that can route traffic between VLANs. To create a VLAN, the administrator needs to configure the network devices that are involved in the VLAN, such as switches, routers, and hosts. The administrator also needs to assign a unique VLAN ID to each VLAN, which is a number between 1 and 4094 that identifies the VLAN1.
In Nutanix AHV, the administrator can create a Nutanix managed network with a specific VLAN ID for guest VMs. This network can be assigned to VM NICs using Prism Element or Prism Central. However, creating a Nutanix managed network does not automatically create the VLAN on the upstream switches that connect the AHV hosts. The administrator needs to manually configure the upstream switches to allow the VLAN traffic on the ports that connect to the AHV hosts. The administrator also needs to ensure that the upstream switches are interconnected physically or virtually and can forward traffic between different VLANs if needed2.
Therefore, if an administrator has created a Nutanix managed network with a VLAN ID of 512 and notices that the VMs on that network can only communicate with other VMs on the same host, but not with VMs on different hosts in the cluster, the most likely cause of this issue is that the VLAN was not created on the upstream switches. This means that the switches are dropping or blocking the traffic with VLAN ID 512 and preventing it from reaching other hosts or VMs. To resolve this issue, the administrator should create the VLAN on the upstream switches and allow it on the ports that connect to the AHV hosts3.
質問 # 102
What is a requirement to enable Flow Neworking?
- A. A dedicated virtual switch has been created for Flow Networking.
- B. Flow Micro segmentation must be enabled.
- C. Microservices infrastructure must be enabled.
- D. Prims Central is using a three-node scale-out deployment
正解：C
解説：
Flow Networking is a feature that enables software-defined networking for AHV clusters. It allows users to create and manage virtual private clouds (VPCs), subnets, and network services such as NAT, DHCP, routing, and VPN. Flow Networking also supports service insertion and chaining, which enables integration with third-party network functions such as firewalls and load balancers. Flow Networking is built on top of the microservices infrastructure (MSP) in Prism Central, which provides the platform for running various Nutanix services such as Calm, Karbon, and Objects. Therefore, to enable Flow Networking, the MSP must be enabled first on Prism Central1. The MSP can be enabled from the Prism Central settings page or from the command line interface (CLI) of the Prism Central VM2. Enabling the MSP will also enable Flow Microsegmentation, which is another feature that provides network security and visibility for AHV clusters.

質問 # 104
Refer to Exhibit:
An administrator needs to enable inline deduplication for a pre-existing storage container. When trying to enable deduplication on the storage container. this feature is grayed-out.
What is the reason for this behavior?
- A. The cluster has less than 5 nodes which is the minimum node-count to enable deduplication.
- B. Capacity reservation is not enabled on the storage container.
- C. Replication Factor 1 is configured on the storage container.
- D. The cluster has hybrid storage and deduplication is supported only on all-flash clusters.
正解：D
解説：
Nutanix supports two types of deduplication: post-process and inline. Post-process deduplication runs periodically on a schedule and can be enabled on any cluster. Inline deduplication runs in real time before data is written to disk and can be enabled only on all-flash clusters.
Therefore, by checking the type of storage and the type of deduplication, you can determine if you can enable inline deduplication on a storage container or not.
Nutanix inline deduplication is a feature that reduces the stored size and avoids duplicate data on a storage container1. It is recommended only on some specific scenarios, such as when using Nutanix Files or virtual desktop infrastructure (VDI) workloads12.

質問 # 109
Refer to Exhibit:
An administrator is attempting to create an additional virtual switch on a newly deployed AHV cluster, using the two currently disconnected interfaces. The administrator is unable to select the disconnected interfaces when creating the virtual switch.
What is the likely cause of this issue?
- A. Interfaces must be assigned to virtual switches via the cli
- B. The disconnected interfaces are currently assigned to virtual switch 0,
- C. Only one interface is available on the selected hosts.
- D. Interfaces must be connected to the network before they can be assigned.
正解：B
解説：
when you create a new virtual switch on AHV, you need to select one or more uplink interfaces that are connected to a physical network. You cannot select an interface that is already assigned to another virtual switch. By default, AHV creates a virtual switch called br0 that uses all available interfaces on the host2.
Therefore, if you want to use some of those interfaces for another virtual switch, you need to remove them from br0 first.

質問 # 110
When a VM is connected to a Nutanix managed network, when is the IP addressed assigned?
- A. When the vNIC is created on the VM.
- B. When the guest OS sends a DHCP request.
- C. When the guest OS receives a DHCP acknowledge.
- D. When the VM is powered on.
正解：D
解説：
When a VM is connected to a Nutanix managed network, the IP address is assigned when the VM is powered on. A Nutanix managed network is a network that is created and managed by Prism Central using IP address management (IPAM). IPAM allows Prism Central to automatically assign IP addresses to VMs from a pool of available addresses in a subnet. IPAM also tracks the IP address usage and availability across clusters and networks4.
When a VM is connected to a Nutanix managed network, the administrator can choose one of the following assignment types for the IP address:
* Assign Static IP: This option allows the administrator to manually specify a static IP address for the VM from the subnet range. The IP address will not change unless the administrator changes it.
* Assign with DHCP: This option allows Prism Central to dynamically assign an IP address for the VM from the subnet range using DHCP. The IP address may change depending on the DHCP lease time and availability.
* No Private IP: This option allows the administrator to skip assigning an IP address for the VM. This option is useful for scenarios where the administrator wants to use an external IPAM solution or assign an IP address later5.
Regardless of the assignment type, the IP address is assigned when the VM is powered on. This is because Prism Central needs to communicate with the hypervisor (AHV or ESXi) to configure the virtual NIC (vNIC) of the VM with the IP address information. This communication can only happen when the VM is in a powered on state6.

質問 # 111
When creating a VM on an AHV cluster, how is the initial placement of the VM determined?
- A. AHV uses a round robin algorithm, placing new VMs onto hosts based on the numerical order of their UUID
- B. Placement is determined by the host that holds the new_VM token at the time of VM creation
- C. The Acropolis Dynamic Scheduler selects a host which provides adequate resources for the VMs configuration
- D. The administrator right clicks on the desired host and selectsPower on VMfrom the dropdown menu
正解：C
解説：
According to section 6 of the exam blueprint guide1, one of the topics covered is VM placement options.
When creating a new VM on an AHV cluster, there are two ways to determine its initial placement:
* Automatic placement: The Acropolis Dynamic Scheduler (ADS) selects a host that provides adequate resources for the VM's configuration, such as CPU, memory, disk space, and network bandwidth. ADS also considers factors such as host load, power state, availability domains, and affinity rules.
* Manual placement: The administrator can specify a host or a host group where they want to place the VM.
