HPE2-K45 Practice Exam Questions with Answers Using HPE SimpliVity Certification

 HPE Storence Management Console is a web-based management interface for HPE StoreOnce Systems, which are backup appliances that provide deduplication and replication capabilities. One of the features that can be configured using HPE Storence Management Console is the Catalyst store, which is a logical container for backup data that supports Catalyst protocol. Catalyst protocol is a proprietary protocol that enables source-side deduplication, low-bandwidth replication, and direct backup from application servers. Backup policy, storage policy, and deduplication ratio are not specific to HPE Storence Management Console, and can be configured using other tools or interfaces. References: HPE StoreOnce system software, section “Software Details”. The StoreOnce System Management Console, section “The StoreOnce System GUI and CLI together make up the Management Console”. HPE StoreOnce Catalyst User Guide, section “Introduction to HPE StoreOnce Catalyst”.

According to the HPE SimpliVity Administration Guide1, one of the major considerations for integrating HPE Storence with HPE SimpliVity is the physical location of the HPE Storence system. The guide recommends that the HPE Storence system should be located in a third site that is independent from the two HPE SimpliVity sites, and that the network latency between the sites should be less than 10 ms. This ensures that the HPE Storence system can act as a reliable backup target for the HPE SimpliVity federation, and that the backup and restore operations can be performed efficiently and securely. The other options are not correct because:

• The number of HPE Storence/SimpliVity integration licenses is not a major consideration for this integration. The HPE SimpliVity federation does not require any additional licenses to integrate with HPE Storence1.
• The number of the stores configured with HPE SimpliVity is not a major consideration for this integration. The HPE SimpliVity federation can integrate with any number of HPE Storence stores, as long as they are configured with the HPE Storence Catalyst protocol1.
• The limited support from software-optimized HPE SimpliVity models is not a major consideration for this integration. The HPE SimpliVity federation can integrate with HPE Storence regardless of the hardware model of the HPE SimpliVity nodes, as long as they are running the same software version1. References: 1: HPE SimpliVity Administration Guide (A00019350ENW), pages 105-107.

The Support Capture file is a compressed file that contains diagnostic data from the HPE SimpliVity hosts, such as system status information and log files. The system status information includes the configuration, performance, and health of the host and its components, such as the HPE OmniStack Virtual Controller, the HPE OmniStack Accelerator Card, the datastore, the network, and the virtual machines. The log files include the messages and events that are generated by the host and its components, such as the kernel, the hypervisor, the HPE SimpliVity software, and the HPE SimpliVity hardware1. The Support Capture file is used by the HPE Support team to troubleshoot and resolve issues with the HPE SimpliVity system.

The other options are not included in the Support Capture file. The license entitlement is the information that verifies the customer’s right to use the HPE SimpliVity software and features, but it is not part of the diagnostic data2. The HPE InfoSight connection parameters are the settings that enable the HPE SimpliVity system to connect to the HPE InfoSight cloud-based platform for predictive analytics and proactive support, but they are not part of the diagnostic data3. The security token to access the system remotely is a temporary credential that allows the HPE Support team to access the HPE SimpliVity system via a secure tunnel, but it is not part of the diagnostic data.

The Persistent Storage layer is the lowest layer of the HPE SimpliVity Data Visualization Platform. It is responsible for storing and tracking all data and metadata on the HPE SimpliVity nodes. It uses a distributed file system that spans across all nodes in a cluster, and provides high availability, scalability, and performance. The Persistent Storage layer also integrates with the HPE OmniStack Accelerator Card, which enables accelerated data efficiency, global unified management, and built-in data protection12. References: HPE SimpliVity Data Virtualization Platform technical white paper, SimpliVity Data Virtualization Platform Architecture - YouTube

 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:

Before moving a virtual machine to another datastore, you need to take a snapshot of the virtual machine using the HPE SimpliVity plugin in vSphere. This ensures that the virtual machine is in a consistent state and that the data is protected. The snapshot also serves as a backup in case the move operation fails or is interrupted. After taking the snapshot, you can use the HPE SimpliVity move operation to move the virtual machine to the desired datastore, either within the same cluster or across clusters. The move operation preserves the data efficiency and resiliency of the virtual machine, and does not require any downtime or reconfiguration12. References: Move a virtual machine to another datastore - Hewlett Packard Enterprise, HPE SimpliVity frequently asked questions

 According to the HPE SimpliVity documents and learning resources, 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 data and transactions. This means that the application consistent method allows the pending 10 operations to finish before committing them to the database, and flushes the memory buffers and caches to the disk. This ensures that the cloned virtual machine can resume the application without any data loss or corruption. The crash consistent method, on the other hand, does not guarantee that the cloned virtual machine is in a consistent state with respect tothe application data and transactions. This means that the crash consistent method does not wait for the pending 10 operations to finish or flush the memory buffers and caches to the disk. This may result in some data loss or corruption if the cloned virtual machine resumes the application. The crash consistent method is faster than the application consistent method, but less reliable. The other options are incorrect because they are either false or irrelevant. Both methods are not the same, and the difference is not only speed of cloning. The crash consistent method can be used for any virtual machine, not only for those with Fault Tolerance enabled. The application consistent method is available for both Windows and Linux operating systems, not only for Linux. References: Clone a virtual machine; HPE SimpliVity frequently asked questions, page 17; Using HPE SimpliVity Official Certification Study Guide, page 65
