Which is NOT a valid source CIDR for a security list rule in an Oracle Cloud Infrastructure (OC'II Virtual Cloud Network (VCN)?

Show Suggested Answer Hide Answer
Suggested Answer: A

'oci-local-vcn' is not a valid source CIDR for a security list rule in Oracle Cloud Infrastructure VCNs. Security list rules are configured using CIDR notation to specify allowed or denied IP address ranges for ingress and egress traffic. Valid CIDR notations include specific IP ranges like '0.0.0.0/0', '10.0.1.0/24', and '192.168.1.0/24'.

That makes sense. So, the correct answer should be B) 0.0.0.0/0 as it's too broad.

oci-local-vcn represents the local VCN and allows instances within the same VCN to communicate.

Hmm, I'm not sure about that. Can you explain why you think oci-local-vcn is valid?

I agree with Queen, 0.0.0.0/0 is too broad and represents all IP addresses.
