HPE2-K45 Exam Dumps : Using HPE SimpliVity

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

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.

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
• The credentials of the virtual machine where you want to restore the files

After you enter the required information, click OK to start the restore process3.
