You are performing maintenance on an HPE Cray XD2000 chassis populated with four compute nodes. One node requires a DIMM replacement.
Does the chassis architecture support servicing a single node without disrupting the operation of the other nodes in the same chassis?
- A . No, the entire chassis must be powered down to remove the shared cover.
- B . No, pulling one node disconnects the shared power bus for all nodes.
- C . Yes, the shared infrastructure allows individual serviceability of nodes without impacting the operation of others.
- D . Yes, but you must put the entire chassis into maintenance mode in HPCM first.
An AI Administrator wants to enable a DAG so that all users in the platform can view its code and trigger runs, regardless of their specific role.
Which access_control configuration achieves this "public read/execute" behavior?
- A . access_control={‘User’: {‘can_read’}, ‘Guest’: {‘can_edit’}}
- B . access_control={‘All’: {‘can_read’, ‘can_edit’}}
- C . access_control={‘Public’: {‘read_write’}}
- D . access_control={‘Everyone’: {‘full_access’}}
An administrator needs to delete a custom framework that failed to install correctly. They receive an error stating that the chart already exists, preventing a clean re-installation. They decide to manually remove the chart from the internal ChartMuseum.
Which API command format should the administrator use to delete the specific chart version from the internal repository?
- A . kubectl delete helmchart <chart_name>
- B . helm delete <chart_name>
- C . rm -rf /var/lib/charts/<chart_name>
- D . curl -X DELETE http://chartmuseum…/api/charts/<chart_name>/<version>
You are troubleshooting a Ray Dashboard in HPE AI Essentials. The dashboard loads, but the "Cluster Metrics" charts (CPU/GPU history) are completely empty. You verify that Ray jobs are running.
What is the missing component or configuration required to populate these specific charts?
- A . A dedicated Grafana instance must be installed on the Ray Head node itself (via framework configuration) to visualize these specific metrics.
- B . The user must have "Super Admin" privileges to see metrics.
- C . The Prometheus Node Exporter service has stopped on all worker nodes.
- D . The browser is blocking pop-ups.
Which ASIC powers the HPE Slingshot switch blades found in the HPE Cray EX system, enabling features like 64-port high-radix connectivity and hardware-based congestion control?
- A . Broadcom Tomahawk
- B . Rosetta
- C . Mellanox Switch-IB
- D . Intel Tofino
How does the Prometheus server in HPE Private Cloud AI obtain metrics from the various targets (like Node Exporter, MySQL, or Kubernetes components)?
- A . The Retrieval component pulls (scrapes) metrics from the targets at regular intervals.
- B . The targets push metrics to the Prometheus server via a REST API.
- C . The targets send email reports to Prometheus.
- D . The targets write metrics to a shared NFS volume that Prometheus reads.
In an HPE Cray Storage Systems C500 Hybrid configuration, data must be moved between the Flash tier (CSU) and the Disk tier (5U84) based on usage policies.
Which component provides the compute resources to execute these data movement operations (tiering)?
- A . The Client Compute Nodes, which use their CPU cycles to copy data.
- B . The LNet Routers, which intercept packets and redirect them.
- C . The 5U84 Enclosure itself, which has embedded tiering controllers.
- D . The System Management Unit (SMU), which runs integrated data mover services.
During the initial setup of an HPE Cray EX supercomputer using HPCM, the administrator needs to provision the operating system to 5,000 compute nodes.
What is a key performance characteristic of HPCM’s provisioning engine that makes it suitable for this scale?
- A . It requires each node to be manually rebooted by a technician to initiate the PXE boot.
- B . It relies on peer-to-peer BitTorrent sharing between nodes, which takes 24 hours to converge.
- C . It can provision thousands of cluster nodes in parallel, completing the task in as little as one hour.
- D . It provisions nodes sequentially (one at a time) to prevent network storms.
If the ezuserconfig is deleted and the user is removed from Keycloak, but onboarding still fails or hangs, which backend service pod might require a restart ("bounce") to clear a stuck processing state?
- A . istio-ingressgateway (in the istio-system namespace)
- B . jupyter-web-app (in the kubeflow namespace)
- C . kube-apiserver (in the kube-system namespace)
- D . tenant-operator (in the hpe-tenant namespace)
An HPC Network Architect is explaining the performance characteristics of the HPE Slingshot interconnect to a customer running a weather simulation model that generates massive amounts of small, unordered MPI messages.
How does HPE Slingshot’s Adaptive Routing mechanism handle this specific type of "unordered" traffic to maximize link utilization?
- A . It buffers all packets at the ingress switch until a dedicated circuit is established.
- B . It uses packet-by-packet adaptive routing, sending individual packets across different paths based on real-time congestion, ensuring high bandwidth utilization without head-of-line blocking.
- C . It uses flow-based hashing (ECMP) to ensure all packets in the stream follow the exact same path.
- D . It encapsulates the traffic in TCP/IP frames to guarantee ordering at the expense of latency.
