Oracle Cloud Infrastructure 2022 Architect Associate — Question 34

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

Answer options

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

Correct answer: A

Explanation

Option A is incorrect because overlapping CIDR prefixes can cause routing issues and conflicts within the network. The other options (B, C, D) correctly describe valid practices for managing VCNs, such as using separate route tables for traffic control, tagging for organization, and reserving IP addresses for future needs.
