Oracle Cloud Infrastructure 2022 Architect Associate — Question 27

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

Correct answer: C

Explanation

The correct answer, C (192.168.0.0/16), represents a valid private IP address range as per RFC 1918, suitable for use in a Virtual Cloud Network. Options A (10.0.0.0/8) and F (172.16.0.0/12) are also valid RFC 1918 ranges, but only option C was specified as correct in this context. Options B (0.0.0.0/0) and D (189.215.154.89/32) are not private addresses, and E (192.268.0.0/24) is invalid due to the incorrect octet.
