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

Correct answer: A

Explanation

Option A, 192.168.0.0/16, is a valid private IP address range defined by RFC 1918, suitable for VCNs. Option B contains an invalid IP, while options E and F are public IPs and a default route, respectively, which do not meet the RFC 1918 criteria. Option C and D are also valid RFC 1918 prefixes but do not match the correct answer as per the question's requirement.
