HPE2-K45 Exam Dumps : Using HPE SimpliVity

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.

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”.

• 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:
