You are configuring networking for a new AI cluster in your data center. The cluster will handle large-
scale distributed training jobs that require fast communication between servers.
What type of networking architecture can maximize performance for these AI workloads?
Select the answer
1 correct answer
A.
Implement a leaf-spine network topology using standard Ethernet switches to ensure scalability as more nodes are added.
B.
Prioritize out-of-band management networks over compute networks to ensure efficient job scheduling across nodes.
C.
Use standard Ethernet networking with a focus on increasing bandwidth through multiple connections per server.
D.
Use InfiniBand networking to provide low-latency, high-throughput communication between servers in the cluster.

Quiz

5/10
You are a Solutions Architect designing a data center infrastructure for a cloud-based AI application
that requires high-performance networking, storage, and security. You need to choose a software
framework to program the NVIDIA BlueField DPUs that will be used in the infrastructure. The
framework must support the development of custom applications and services, as well as enable
tailored solutions for specific workloads. Additionally, the framework should allow for the integration
of storage services such as NVMe over Fabrics (NVMe-oF) and elastic block storage.
Which framework should you choose?
Select the answer
1 correct answer
A.
NVIDIA TensorRT
B.
NVIDIA CUDA
C.
NVIDIA NSight
D.
NVIDIA DOCA

Quiz

6/10
You are managing a Slurm cluster with multiple GPU nodes, each equipped with different types of
GPUs. Some jobs are being allocated GPUs that should be reserved for other purposes, such as
display rendering.
How would you ensure that only the intended GPUs are allocated to jobs?
Select the answer
1 correct answer
A.
Verify that the GPUs are correctly listed in both gres.conf and slurm.conf, and ensure that unconfigured GPUs are excluded.
B.
Use nvidia-smi to manually assign GPUs to each job before submission.
C.
Reinstall the NVIDIA drivers to ensure proper GPU detection by Slurm.
D.
Increase the number of GPUs requested in the job script to avoid using unconfigured GPUs.

Quiz

7/10
A data scientist is training a deep learning model and notices slower than expected training times.
The data scientist alerts a system administrator to inspect the issue. The system administrator
suspects the disk IO is the issue.
What command should be used?
Select the answer
1 correct answer
A.
tcpdump
B.
iostat
C.
nvidia-smi
D.
htop

Quiz

8/10
You have noticed that users can access all GPUs on a node even when they request only one GPU in
their job script using --gres=gpu:1. This is causing resource contention and inefficient GPU usage.
What configuration change would you make to restrict users’ access to only their allocated GPUs?
Select the answer
1 correct answer
A.
Increase the memory allocation per job to limit access to other resources on the node.
B.
Enable cgroup enforcement in cgroup.conf by setting ConstrainDevices=yes.
C.
Set a higher priority for Jobs requesting fewer GPUs, so they finish faster and free up resources sooner.
D.
Modify the job script to include additional resource requests for CPU cores alongside GPUs.

Quiz

9/10
A new researcher needs access to GPU resources but should not have permission to modify cluster
settings or manage other users.
What role should you assign them in Run:ai?
Select the answer
1 correct answer
A.
L1 Researcher
B.
Department Administrator
C.
Application Administrator
D.
Research Manager

Quiz

10/10
