HP HPE2-K45 Exam With Confidence Using Practice Dumps

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 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 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:
