Oracle Cloud Infrastructure 2021 Architect Associate — Question 38

Which is NOT a valid Oracle Cloud Infrastructure Virtual Cloud Network (VCN) approach?

Answer options

• A. Private subnets are recommended to have individual route tables to control the flow of traffic within and outside of VCN.
• B. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges
• C. Use OCI tags to tag VCN resources so that all resources are following organizational tagging/naming conventions
• D. Ensure not all IP addresses are allocated at once within a VCN or subnet, instead plan to reserve some IP addresses for future use.

Correct answer: B

Explanation

Option B is the correct answer because the CIDR prefix for a VCN should not overlap with any other VCNs or private IP networks to avoid routing conflicts. Options A, C, and D are valid practices for VCN configuration, promoting effective traffic management, organizational compliance, and future scalability.
