Oracle Cloud Infrastructure 2025 Architect Associate — Question 1

Which of the following is a valid RFC 1918 CIDR prefix that can be used for creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN)?

Answer options

• A. 172.16.0.0/12
• B. 189.215.154.89/32
• C. 0.0.0.0/0
• D. 192.168.0.0/16
• E. 10.0.0.0/8
• F. 192.268.0.0/24

Correct answer: D

Explanation

The correct answer is D, 192.168.0.0/16, which is a valid private IP address range as defined by RFC 1918. Options A and E are also valid RFC 1918 prefixes but are not the ones asked for here. Option B is a public IP address, option C is a default route that includes all addresses, and option F has an invalid octet (268), rendering it unusable.
