質問 # 41
What requires iSCSI initiator configuration in the guest OS to use Volumes?

A. Microsoft Windows Failover Cluster
B. SQL Server Always On Availability Group
C. Oracle RAC
D. Exchange DAG

正解：A

解説：
The only option that requires iSCSI initiator configuration in the guest OS to use Volumes is Microsoft Windows Failover Cluster. Volumes is an enterprise-class, software-defined block storage solution that exposesstorage resources directly to virtualized guest operating systems or physical hosts using the iSCSI protocol7. To use Volumes, customers need toconfigure iSCSI initiators on their hosts or guest OSes.
However, some applications or services can use native storage adapters instead of iSCSI initiators when running on AHV VMs. These include:
* SQL Server Always On Availability Group: This is a high availability and disaster recovery solution for SQL Server databases that uses Windows Server Failover Clustering (WSFC) and Availability Groups (AGs) as its core components. When running on AHV VMs, SQL Server Always On Availability Group can use native storage adapters instead of iSCSI initiators.
* Oracle RAC: This is a clustered database system that provides high availability and scalability for Oracle databases. When running on AHV VMs, Oracle RAC can use native storage adapters instead of iSCSI initiators.
* Exchange DAG: This is a group of up to 16 mailbox servers that hosts a set of databases and provides automatic database-level recovery from failures that affect individual servers or databases. When running on AHV VMs, Exchange DAG can use native storage adapters instead of iSCSI initiators.

質問 # 42
A user running a Computer Aided Design (CAD) application is complaining about slow response time within the VM, particular when moving windows or rendering images.
Which VM metric will guide the administrator toward diagnosing the problem?

A. Hypervisor Memory Usage (%)
B. GPU Usage
C. Storage Controller Latency
D. Swap in Rate

正解：B

解説：
A GPU (graphics processing unit) is a specialized hardware device that can accelerate graphics rendering and computation for applications that use APIs such as DirectX, OpenGL, CUDA, and OpenCL. A GPU can also offload the CPU from encoding and decoding tasks for remote display protocols such as Frame Remote Desktop Protocol (FRP). A VM can use a GPU either by directly accessing a physical GPU (pGPU) on the host or by using a virtual GPU (vGPU) that shares a pGPU with other VMs. A user running a computer aided design (CAD) application may benefit from using a GPU or a vGPU to improve the performance and responsiveness of the application, especially when moving windows or rendering images. However, if the GPU or vGPU is not properly configured or provisioned, the user may experience slow response time within the VM. Therefore, to diagnose the problem, the administrator should monitor the GPU Usage metric for the VM. The GPU Usage metric shows the percentage of GPU resources that are consumed by the VM over time3. The administrator can use Prism Central to view the GPU Usage metric for each VM in a chart or a widget4. The administrator can also use Prism Central to view other metrics related to GPU performance, such as GPU Memory Usage, GPU Encoder Usage, and GPU Decoder Usage3. By analyzing these metrics, the administrator can determine if the VM is using the GPU efficiently and optimally, or if it needs more or less GPU resources.

質問 # 43

D. Network latency

正解：D

質問 # 44
An administrator wants to expand the Failure Domain level of a cluster.
What two options are available? (Choose two.)

A. Node
B. Block
C. Rack
D. Data Center

正解：B、C

解説：
Nutanix clusters are resilient to a drive, node, block, and rack failures because they use redundancy factor 2 by default, allowing Nutanix clusters to self-heal2. Failure scenarios can be thought of in terms of fault domains, which are the physical or logical parts of a computing environment or location that are adversely affected when a device or service experiences an issue or outage3. There are four fault domains in a Nutanix cluster: Disk, Node, Block, and Rack4. Block and Rack are two options that are available for expanding the failure domain level of a cluster. Block fault tolerance is enabled by default and ensures that data is replicated across different blocks in a cluster5. Rack fault tolerance has to be configured manually and ensures that data is replicated across different racks in a cluster4.

質問 # 45
How many SSL certificates are used by Prism Element on a Nutanix cluster?

A. 0
B. 1
C. 2
D. 3

正解：D

質問 # 46
Refer to Exhibit:

Which statement is true?

A. A critical alert will be triggered when there is an anomaly above 4000 MB.
B. A warning alert will be triggered if I/O working set size goes over the blue band.
C. A warning alert will be triggered after 3 anomalies have been catch.
D. A critical alert will be triggered if I/O working set size goes over 6000 MB.

正解：A

解説：
A). This statement is incorrect because there is no static threshold set to trigger a critical alert at 6000 MB. The graph shows a peak that goes above 6000 MB, but the alert configuration below does not specify a static threshold at this value.
B). This is the correct statement. The configuration under "Behavioral Anomaly" is set to alert every time there is an anomaly, with a critical level alert set to trigger when the I/O working set size is between 0 MB and 4000 MB. The graph illustrates that the anomalies (highlighted in pink) occur when the working set size exceeds the normal range (blue band). Therefore, any anomaly detected above 4000 MB would trigger a critical alert.
C). This statement is incorrect because there is no indication that a warning alert is configured to trigger after 3 anomalies. The exhibit does not show any configuration that specifies an alert based on the number of anomalies.
D). This statement is incorrect as there's no indication that a warning alert will be triggered based on the I/O working set size exceeding the blue band. The alert settings are configured to ignore anomalies below 4000 MB and to trigger a critical alert for anomalies above this threshold.
The settings displayed in the exhibit are typically part of Nutanix's Prism infrastructure management platform, which can set various thresholds for performance metrics and trigger alerts based on those thresholds. The behavior is defined in the Prism documentation where the alert configuration is outlined.

質問 # 47

正解：B

質問 # 48
What Nutanix feature provides effective caching optimization In VDI environments?

A. Remote Protection Group
B. Shadow Clones
C. Snap Clones
D. Local Protection Group

正解：B

解説：
Shadow Clones is a Nutanix feature that provides effective caching optimization in VDI environments. VDI stands for Virtual Desktop Infrastructure, which is a technology that allows users to access virtual desktops hosted on a centralized server. VDI environments typically have a high degree of similarity among desktop images, which means that many VMs access the same data blocks from the storage layer. Shadow Clones leverages this similarity by creating read-only copies of frequently accessed data blocks on each node's SSD tier, reducing network traffic and improving performance. Shadow Clones works automatically and transparently without any configuration or intervention from the administrator.

質問 # 49
Which component can be associated with a storage policy?

A. Catalog
B. Subnet
C. Vm
D. Category

正解：C

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-clust

質問 # 50
An administrator needs to configure a new subnet on an AHV cluster and want to ensure that VMs will automatically be assigned an IP address at creation time.
Which type of network does the administrator need to create?

A. Dynamic Network
B. DHCP Network
C. Managed Network
D. Unmanaged Network

正解：C

解説：
A managed network is a type of network that can be created on an AHV cluster and allows VMs to automatically be assigned an IP address at creation time. A managed network uses the Nutanix IP Address Management (IPAM) service, which provides DHCP and DNS functionality for the VMs on the network. A managed network can be configured with a subnet range, a default gateway, and DNS servers. The IPAM service will allocate IP addresses from the subnet range to the VMs and register their hostnames in the DNS servers. The IPAM service will also release the IP addresses when the VMs are deleted or moved to another network1.
To create a managed network on an AHV cluster, the administrator can use Prism Element or Prism Central. The steps are as follows2:
In Prism Element, go to the Network Configuration page and click Create Network.
In Prism Central, go to the Networks page and click Create.
Enter a name and description for the network.
Select Managed as the network type.
Enter the subnet range, default gateway, and DNS servers for the network.
Optionally, enable VLAN tagging and enter a VLAN ID for the network.
Click Save.
