HPE2-K45 Exam Dumps : Using HPE SimpliVity

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:

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.

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
