Question 21

An AI platform team is investigating poor I/O performance for a specific workload that involves processing hundreds of thousands of small metadata files. The application is running on a Kubernetes cluster with storage provided by a NetApp ONTAP system over NFS. Performance metrics show acceptable network throughput but very high latency for metadata operations (e.g., open, stat, close).
The current storage configuration is as follows:
Storage_System: NetApp AFF A-Series
Protocol: NFSv4.1
Workload_Profile: Metadata-intensive, many small file lookups
Observed_Issue: High latency on metadata operations, slow job completion Which storage architecture would be better suited to handle this specific metadata-intensive workload?
  • Question 22

    An AI research team is experiencing slow model training times. Their performance monitoring indicates that the GPUs are frequently idle, waiting for data. They want to implement a single technology change to create a more direct data path between their storage and GPUs.
    Their current setup is as follows:
    Compute: Server with NVIDIA A100 GPUs
    Storage: NetApp AFF A-Series (All-Flash)
    Network: 100GbE Ethernet
    Data_Path: Storage -> Host CPU/Memory -> GPU Memory
    Which technology should the architect recommend to specifically address this data path inefficiency?
  • Question 23

    A training job on one of the NVIDIA DGX servers is running slowly. A performance engineer runs the 'dstat' command on the server and captures the following output during the job execution.
    -total-cpu-usage- -dsk/total- -net/total- paging-- system-- usr sys idl wai hiq siq| read writ| recv send| in out | int csw 15 5 70 10 0 0| 1.2G 15.0M| 1.2G 12.0M| 0 0 | 15k 35k
    14 6 69 11 0 0| 1.2G 14.3M| 1.2G 11.8M| 0 0 | 14k 33k
    16 5 68 11 0 0| 1.2G 16.1M| 1.2G 13.1M| 0 0 | 16k 36k
    The server is connected to the NetApp ASA via a 100GbE (12.5 GB/s) network.
    What is the most likely performance bottleneck based on this data?
  • Question 24

    An organization's AI platform team needs to provide two distinct tiers of storage for their data scientists on a single Kubernetes cluster:
    1. 'gold-tier': Extremely low-latency storage for active model training, using an all-flash NetApp ASA system.
    2. 'bronze-tier': Cost-effective, high-capacity storage for data staging and archiving, using a NetApp StorageGRID system.
    How should the platform team configure NetApp Trident to meet these requirements? (Select all that apply.)
  • Question 25

    Which of the following platforms can be used to manage containerized AI workloads on Kubernetes? (Choose two)
