Which set of technologies does NVIDIA Spectrum-X utilize to achieve lossless data transmission required for RDMA over Converged Ethernet (RoCE) workloads?
- A . Transmission Control Protocol (TCP) sliding windows
- B . Priority Flow Control (PFC) and Explicit Congestion Notification (ECN)
- C . Spanning Tree Protocol (STP) and Shortest Path Bridging (SPB)
- D . Fiber Channel over Ethernet (FCoE) encapsulation
A customer observes that their legacy InfiniBand cluster experiences significant performance jitter (run-to-run variability) when multiple workloads run simultaneously. They are considering HPE Slingshot.
Which specific capability of the HPE Slingshot QoS (Quality of Service) architecture directly addresses the "noisy neighbor" problem where one workload impacts another?
- A . The ability to detect congestion at the switch level and send backpressure signals specifically to the source NIC causing the congestion, throttling it before it impacts the shared fabric.
- B . The use of a central subnet manager to recalculate routes every 5 minutes.
- C . The use of Deep Packet Inspection (DPI) to drop low-priority packets.
- D . The ability to reserve physical cables for specific jobs.
A Storage Architect is explaining why a traditional All-Flash NAS (Network Attached Storage) solution is often unsuitable for a large-scale HPC cluster, despite having high-speed SSDs.
What is the primary architectural bottleneck of a standard NAS design that limits its scalability for HPC workloads compared to a parallel file system?
- A . NAS systems cannot use NVMe drives.
- B . The single NAS head (controller) handles all metadata and user data services; as the number of compute clients increases, this single point of entry becomes a throughput bottleneck.
- C . NAS systems only support Windows clients (SMB).
- D . NAS systems require Fibre Channel connectivity, which is not supported by Cray EX.
An AI team needs to access a legacy 500TB dataset stored in an on-premises Hadoop Distributed File System (HDFS) from their new HPE Private Cloud AI environment. They do not want to migrate the data.
How can HPE AI Essentials facilitate access to this external data source for training jobs?
- A . By installing the Hadoop YARN resource manager on the Kubernetes control plane.
- B . By converting the HDFS data into S3 objects using a permanent background job.
- C . By configuring a Data Connector that mounts the HDFS volume or accesses it via a proxy layer, allowing the AI tools (like Spark or Notebooks) to consume the data in place.
- D . By automatically copying the 500TB dataset to the local NVMe flash tier during the night.
A Facility Engineer is planning the power infrastructure for a new deployment of HPE Cray EX liquid-cooled cabinets. The cluster will operate at extreme density.
According to HPE specifications, what is the maximum supported power capacity per cabinet that the facility must be able to supply for a fully loaded HPE Cray EX cabinet?
- A . 400 kW
- B . 150 kW
- C . 300 kW
- D . 50 kW
You are sizing the capacity for an HPE Cray Storage Systems C500 Hybrid configuration. The customer needs to add approximately 4 PB of usable capacity using Hard Disk Drives (HDDs) for their "Capacity Tier."
What is the maximum number of 5U84 HDD expansion enclosures supported by a single C500 system to achieve this capacity?
- A . 4 enclosures
- B . 2 enclosures
- C . 8 enclosures
- D . 1 enclosure
A Data Engineer observes that an Airflow DAG scheduled to run every hour has been paused for maintenance for the last 24 hours. They are ready to resume the DAG.
If the DAG’s catchup parameter is set to True (default), what will happen immediately after the engineer toggles the DAG to "Unpause"?
- A . The scheduler will schedule and execute all missed DAG runs from the last 24 hours sequentially or in parallel (depending on concurrency limits).
- B . The scheduler will automatically delete the missing runs to save database space.
- C . The DAG will enter a "Broken" state until the start_date is updated.
- D . The scheduler will ignore the past interval and only schedule the *next* hourly run.
