CUDA, Driver and Framework Version Compatibility Quiz

Answers and explanations appear as you take the quiz.

1. Which component manages the physical GPU from the host operating system?
   • The NVIDIA driver
   • The framework wheel
   • The model checkpoint
   • The Python virtual environment
2. What does a framework's CUDA build tag describe most directly?
   • The exact host driver installed on every machine
   • The CUDA support that framework package was built to use
   • The version of the physical GPU firmware
   • The model's training data format
3. Why may nvcc --version differ from a driver utility's CUDA capability display?
   • Both report the framework version
   • One must be corrupted whenever values differ
   • They report different layers: toolkit compiler versus driver-supported capability
   • They both identify the GPU model only
4. What does CUDA backward compatibility generally allow under documented conditions?
   • An older driver can run applications built with a newer toolkit without a compatibility path
   • Driver and toolkit versions must always have identical minor numbers
   • A sufficiently new driver can run applications built with older CUDA toolkits
   • Any toolkit build works with every older driver
5. A framework imports, but a GPU operation fails. Which conclusion is warranted?
   • The host driver must be correct
   • Package import succeeded, but runtime compatibility still needs diagnosis
   • The model checkpoint is incompatible by definition
   • All CUDA libraries are initialized
6. Where should an engineer verify a supported framework and CUDA combination?
   • A container filename alone
   • An arbitrary version string copied from another project
   • The framework's official release installation guidance and NVIDIA compatibility documentation
   • The newest toolkit regardless of framework build
7. Why change one compatibility layer at a time during troubleshooting?
   • It makes toolkit and driver versions identical
   • It guarantees a newer driver works with every package
   • It avoids recording versions
   • It helps identify which change resolves or causes the failure
8. What should a reproducible GPU bug report record?
   • OS, GPU, host driver, image and framework build
   • Only the framework's major version
   • Only the displayed CUDA capability
   • The user's password and model weights
