Free and Premium HP HPE2-K45 Dumps Questions Answers

According to the HPE SimpliVity documents and learning resources, the best practice for designing an HPE SimpliVity solution is to use nodes with the same drive configuration and capacity within a cluster, and avoid mixing All-flash and hybrid nodes, or nodes with different drive types, sizes, or speeds. This is because mixing nodes with different drive configurations can result in unbalanced 10 performance and capacity utilization, as well as compatibility issues.Therefore, the recommended option for this design is to create a new cluster with HPE SimpliVity 380 Gen10 H SFF nodes at the remote site, and keep the existing cluster with HPE SimpliVity 380 Gen10 hardware accelerated nodes at the primary site. The other options are incorrect because they do not follow the best practice and can cause performance and capacity problems. References: Using HPE SimpliVity Official Certification Study Guide, page 42; HPE SimpliVity networking explained; HPE SimpliVity Releases

Hyper Protected is one of the four pillars of HPE SimpliVity’s value proposition, along with Hyper Simple, Hyper Efficient, and Hyper Manageable. Hyper Protected refers to the ability of HPE SimpliVity to provide built-in data protection and disaster recovery for virtual machines (VMs) with unprecedented speed and efficiency. HPE SimpliVity can backup or restore 1TB VM in less than 1 minute, thanks to its unique data architecture that deduplicates, compresses, and optimizes data at inception, and its global federated management that enables policy-based automation across multiple sites. Restoring individual files from a VM backup, defining a storage policy using RAID 6 or RAID 60 to protect the VM, and integrating with Veeam to provide an external backup solution are not specific to HPE SimpliVity’s Hyper Protected capability, and can be done by other solutions as well. References: Using HPE SimpliVity Official Certification Study Guide, page 11, section 1.2. SimpliVity Hyperconverged, section “Hyper Protected”. HPE SimpliVity 380 Gen10 Node, section “Features”. SimpliVity HyperGuarantee, section “Remain online and recoverable — always”.

To use this option, you need to select the backup from which you want to restore the files, then click Backup Actions > Restore Files. You will be prompted to enter the following information:

• The name of the virtual machine where you want to restore the files
• The path of the folder where you want to restore the files
• The path of the folder that you want to restore from the backup

• HPE SimpliVity 380 Gen10 LFF H and HPE SimpliVity 380 Gen10 SFF H nodes are two types of HPE SimpliVity nodes that differ in their form factor, storage capacity, and performance. LFF stands for large form factor, which means that the node has 3.5-inch hard disk drives (HDDs) and can support up to 40 TB of raw storage capacity. SFF stands for small form factor, which means that the node has 2.5-inch solid state drives (SSDs) and can support up to 23.4 TB of raw storage capacity12.
• HPE SimpliVity nodes can be grouped into clusters, which are logical units of compute and storage resources that share the same configuration and policies. HPE SimpliVity clusters can be further grouped into federations, which are collections of clusters that span across different physical locations and provide unified management and data protection34.
• For this setup, the recommended design is to put SFF and LFF nodes in separate clusters, but within the same federation. According to the HPE SimpliVity Federation Design and Scaling Guide document, the following reasons support this recommendation:

According to the HPE SimpliVity Administration Guide1, the file level restore option allows you to recover individual files or folders from a backup of a virtual machine. Thisoption is useful when you need to restore a specific file that was accidentally deleted or corrupted, without affecting the rest of the virtual machine. The file level restore option supports both Windows and Linux based virtual machines, and can be performed using the HPE SimpliVity plugin in the vSphere Web Client. The file level restore option creates a temporary virtual machine from the backup, mounts the virtual disks, and copies the selected files or folders to a destination of your choice. The temporary virtual machine is then deleted automatically.

The other options are not suitable for recovering a single file from a Linux based virtual machine. Restoring a virtual machine from the backup would overwrite the entire virtual machine with the backup data, which may not be desirable or necessary. Moving a virtual machine from DR site to the primary site would not help if the file was deleted from both sites. Reverting to the SimpliVity snapshot would also overwrite the entire virtual machine with the snapshot data, which may not be the latest or the most relevant version. References:

• Register External Store …1

This option allows you to register an HPE StoreOnce Catalyst Store as an external backup target for HPE SimpliVity. This enables you to store VM backups on an HPEStoreOnce system, which is a disk-based backup solution that offers deduplication, compression, encryption, remote replication, and direct application-managed integration2.

To use this option, you need to have an HPE StoreOnce appliance connected to your HPE SimpliVity cluster, and configure a Catalyst Store on it. Then, you can select the All HPE SimpliVity Actions menu, and click Register External Store. You will be prompted to enter the following information:

• The name of the external store
• The IP address or hostname of the HPE StoreOnce appliance
• The name of the Catalyst Store
• The credentials of the Catalyst Store

After you enter the required information, click OK to register the external store1.

 According to the HPE SimpliVity documents and learning resources, the HPE SimpliVity 380 Gen10 is the only model that can be equipped with the HPE mniStack Accelerator card. The HPE mniStack Accelerator card is a PCIe-based card that provides hardware acceleration for data compression and deduplication. It also enables the HPE SimpliVity RapidDR feature, which automates and simplifies disaster recovery operations. The other models, such as the HPE SimpliVity 2600, the HPE SimpliVity 380 Gen10 H, and the HPE SimpliVity 325 Gen10, do not support the HPE mniStack Accelerator card. They rely on software-based data efficiency and backup features. References: Using HPE SimpliVity Official Certification Study Guide, page 29; HPE SimpliVity networking explained; HPE SimpliVity Releases

• A stretched cluster is a configuration that allows two or more HPE SimpliVity clusters to span across different physical locations, while maintaining a single logical cluster and asingle management interface. A stretched cluster provides high availability, disaster recovery, and workload mobility for the virtual machines (VMs) running on the HPE SimpliVity platform12.
• A VDI infrastructure is a virtualization solution that delivers desktops and applications to end users from a centralized data center. VDI infrastructure can use different types of VMs, such as linked clones or full clones, to provide the desktops and applications to the end users. Linked clones are VMs that share a common base image and consume less storage space, while full clones are VMs that have their own independent copies of the base image and consume more storage space34.
• According to the HPE Reference Architecture for VMware Horizon on HPE SimpliVity document, both linked clones and full clones are supported on a stretched cluster. The document states that "HPE SimpliVity supports both linked clones and full clones on a stretched cluster. Linked clones are recommended for better storage efficiency and performance. Full clones can be used for persistent desktops that require more customization and personalization."5 The document also provides the design considerations and best practices for deploying VDI infrastructure on HPE SimpliVity stretched cluster, such as the network requirements, the VM placement, the backup and restore policies, and the failover and failback scenarios.

 According to the HPE InfoSight for HPE SimpliVity Getting Started document1, HPE InfoSight provides the following functionality for HPE SimpliVity:

• Monitoring of cluster, node, and virtual machine performance, capacity, and health
• Reporting of system configuration, inventory, and compliance
• Analysis of trends, anomalies, and root causes
• Prediction of future resource needs and potential issues
• Recommendation of best practices and optimization actions

One of the key features of HPE InfoSight is the ability to monitor the latency of virtual machines, which is the time it takes for a request to be processed by the system. Latency is an important indicator of the performance and efficiency of the system, and HPE InfoSight provides detailed and granular data on the latency of each virtual machine, as well as the breakdown of the latency components, such as CPU, memory, network, and storage. HPE InfoSight also provides alerts and notifications when the latency exceedsthe predefined thresholds, and helps to identify and resolve the root causes of the latency issues.

Therefore, the correct answer is D. monitoring of virtual machine latency, as this is one of the functionality that HPE InfoSight provides for HPE SimpliVity. References:

The correct answer is A. All VMs on the node restart in a node where the replica resides. This is because HPE SimpliVity uses a replication factor (RF) of 2 or 3 to ensure that each virtual machine (VM) has one or two copies of its data on different nodes in the cluster. If an HPE OmniStack Virtual Controller (VC) fails, the VMs on that node lose access to their primary data, but they can still access their replica data on another node. The vSphere HA feature detects the VC failure and restarts the VMs on the node where the replica resides, ensuring data availability and continuity1.

The other options are not correct. Option B is incorrect because HPE SimpliVity Intelligent Workload Optimizer (IWO) is a feature that balances the VMs across the cluster based on CPU and memory utilization, not on VC failures2. Option C is incorrect because the IP address of the VC does not fail over to another node, but remains associated with the failed node. The VMs on the failed node are restarted on another node with a different VC IP address3. Option D is incorrect because the VMs on the node do not go on standby mode, but are restarted on another node to resume their operations.

You can apply a backup policy at the datastore level, as this is the level at which HPE SimpliVity manages the virtual machines and their backups1. A backup policy consists of one or more rules that specify the destination, frequency, and retention of the backups. You can assign a backup policy to a datastore, and all the virtual machines in that datastore will inherit the backup policy. You can also override the backup policy for individual virtual machines, if needed2. Applying a backup policy at the cluster level (option A), the datacenter level (option B), or the vCenter Server level (option C) is not possible, as these are not the levels at which HPE SimpliVity manages the virtual machines and their backups. These levels are used for organizing and managing the ESXi hosts and the HPE SimpliVity nodes, but not for applying backup policies. References:

 The difference between crash consistent and application consistent cloning methods is that the application consistent method ensures that the cloned virtual machine is in a consistent state with respect to the application and database, while the crash consistent method does not guarantee that1. The application consistent method uses the VMware snapshot or the Microsoft Volume Shadow Copy Service (VSS) to quiesce the application and flush the pending I/O operations to the disk before creating the clone, which prevents data corruption or loss2. The crash consistent method does not quiesce the application or flush the pending I/O operations, and creates the clone as if the virtual machine had crashed, which may result in data inconsistency or recovery issues3. The application consistent method is recommended for virtual machines that run database applications, such as SQL Server or Oracle, while the crash consistent method is suitable for virtual machines that run non-database applications, such as web servers or file servers4. The application consistent method is not available only for Linux operating systems (option D), as it also supports Windows Server operating systems that have VMware Tools or VSS installed5. The crash consistent method should not be used only for the virtual machines with Fault Tolerance enabled (option C), as it can be used for any virtual machine that does not require application consistency. Both methods are not the same,and the speed of cloning is not the only difference (option B), as they have different implications for the data integrity and availability of the cloned virtual machine. References:
