HPE0-V27 Practice Questions

HPE Alletra 9000 is a cloud-native data infrastructure that delivers a cloud experience for mission-critical workloads. It is designed to provide extreme low-latency, reliability, and performance density in a 4U enclosure. Some of the business values of HPE Alletra 9000 are:

100% uptime guarantee: HPE Alletra 9000 ensures resiliency with a guaranteed 99.9999% data availability, backed by the HPE Alletra Availability Guarantee program 1 .  It also offers built-in data protection, replication, and disaster recovery capabilities to safeguard data from any eventuality 2 .

Enterprise scalability and performance: HPE Alletra 9000 delivers consistent sub-millisecond latency and up to 15M IOPS for the most demanding applications 1 .  It also supports massive scalability, with up to 96 NVMe drives and 6PB of raw capacity per system, and up to 4 systems in a single namespace 2 .  HPE Alletra 9000 can also easily extend to the cloud with consistent data services and native integration with cloud platforms 3 .

According to the  Advanced HPE Edge-to-Cloud Solutions , page 98, the following matches are correct:

Communicates key parameters between DCB-capable devices. = DCBX

Enables control over how much bandwidth can be used over a conventional link. = ETS

Helps to ensure that Ethernet can provide the lossless frame delivery of FCo

E.  

= PFC

Provides instructions to CNA about application-to-CoS mapping. = APP

DCBX: Data Center Bridging Exchange Protocol. It is a protocol that enables the exchange of configuration and capability information between DCB-capable devices, such as switches and servers.  It allows the devices to negotiate and agree on the parameters for the DCB features, such as ETS, PFC, and APP 1 .

ETS: Enhanced Transmission Selection. It is a feature that enables the allocation of bandwidth to different traffic classes on a link, based on the priority and the service level agreement.  It allows the devices to control how much bandwidth can be used by each traffic class, and to avoid congestion and contention on the link 1 .

PFC: Priority-based Flow Control. It is a feature that enables the pause and resume of traffic on a link, based on the priority and the buffer availability.  It allows the devices to prevent the loss of frames due to buffer overflow, and to ensure the lossless delivery of FCoE traffic, which requires reliable and in-order transmission 1 .

APP: Application Priority. It is a feature that enables the mapping of applications to traffic classes on a link, based on the priority and the quality of service.  It allows the devices to instruct the Converged Network Adapter (CNA) about which traffic class to use for each application, and to optimize the performance and efficiency of the traffic 1 .

HPE GreenLake Data Protection is a cloud service that provides backup and recovery solutions for hybrid cloud environments. It enables customers to protect their data from edge to cloud, with rapid recovery on premises or low-cost archiving in the cloud.  It also offers ransomware protection, data mobility, and data analytics capabilities 1 .

Two of the components that are part of HPE GreenLake Data Protection are:

Disaster recovery: HPE GreenLake Data Protection offers disaster recovery as a service (DRaaS) based on Zerto, a leading platform for cloud data management and protection 2 . DRaaS enables customers to replicate and recover their data and applications across different sites, regions, or clouds in minutes, with minimal data loss and downtime.  DRaaS also provides orchestration, automation, and testing tools to simplify and streamline the disaster recovery process 2 .

Azure blob backup: HPE GreenLake Data Protection supports Azure blob backup, which allows customers to backup their data to Azure Blob Storage, a scalable and cost-effective cloud storage service 3 . Azure blob backup can be used for long-term retention, compliance, or archival purposes, as well as for restoring data to Azure or on-premises environments.  Azure blob backup also leverages deduplication, compression, and encryption technologies to optimize the backup performance and security 3 .

The other options, such as application mobility, CSI plugin, and object gateway, are not components of HPE GreenLake Data Protection.  Application mobility is a feature of Zerto that enables customers to migrate their applications across different platforms, such as VMware, Hyper-V, AWS, Azure, or Google Cloud, without disruption or data loss 4 . CSI plugin is a container storage interface plugin that enables customers to provision and manage persistent storage for their containerized applications using HPE storage solutions. Object gateway is a component of HPE Ezmeral Data Fabric, a data platform that provides a unified and secure data layer for analytics, AI, and cloud-native applications.
