Oracle Cloud Infrastructure 2020 Architect Associate — Question 29

Which statement is true about interconnecting Virtual Cloud Network (VCN)?

Answer options

• A. VCNs support transitive peering.
• B. Peering VCNs should not have overlapping CIDR blocks.
• C. VCNs must be in the same tenancy to be peered.
• D. The only way to interconnect VCNs is through peering.

Correct answer: B

Explanation

Option B is correct because when peering VCNs, their CIDR blocks must not overlap to avoid routing conflicts. Option A is incorrect as transitive peering is not supported. Option C is false because VCNs in different tenancies can be peered under certain conditions. Option D is misleading; while peering is a key method, there are other ways to connect VCNs, such as through VPNs or FastConnect.
