You are a data scientist working inside a notebook session and you attempt to pip install a package from a public repository that is not included in…

Detailed Answer in Step-by-Step Solution:

Objective: Diagnose a network timeout during pip install in a notebook session.

Understand Notebook Networking: Sessions run in a VCN; internet access requires specific configs.

Analyze Timeout: Indicates failure to reach the public PyPI repository—likely no internet outbound

route.

Evaluate Options:

A: NAT Gateway—Provides internet access for private subnets—correct fix. B: Service

Gateway—Accesses OCI services privately, not public internet. C: FastConnect—Links to on-premises,

not public internet.

D: VNIC—Essential but present by default; doesn’t solve internet access. Reasoning: NAT Gateway

enables outbound traffic to public repos like PyPI. Conclusion: A is correct.

OCI documentation notes: “Notebook sessions in a private subnet require a NAT Gateway to access

public internet resources, such as PyPI, for package installation via pip. Without it, network timeouts

occur.” Service Gateway (B) is for OCI services, FastConnect (C) is irrelevant, and VNIC (D) is

standard—only A resolves the issue.
