Securing Cluster Interconnect Communication in Oracle RAC
Secure Cluster Communication protects the cluster interconnect from common security threats when used together with Single Network Support. Secure Cluster Communication includes message digest mechanisms, protection against fuzzing, and uses Transport Layer Security (TLS) to provide privacy and data integrity between the cluster members. Which statement is true about securing cluster interconnect communication?
Community Votes
100% of anonymous learners picked answer A. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The question tests knowledge of automatic security features in GI 19c, specifically that secure interconnect communication is activated without user intervention.
In Oracle Grid Infrastructure 19c, Secure Cluster Communication is enabled by default to protect the cluster interconnect using TLS. This feature requires no manual configuration from administrators during deployment or upgrade.
Candidates often assume that securing network traffic always requires manual certificate management or key provisioning, leading them to choose options involving wallets or certificates.

Expert Analysis
Why the Answer Is Correct
Option A is correct because Oracle introduced Secure Cluster Communication as a default feature in Grid Infrastructure 19c. According to official release notes, this security layer is automatically invoked during new deployments or upgrades, ensuring privacy and data integrity via TLS without requiring any configuration changes from DBAs or cluster admins.Why the Other Options Are Wrong
Options B, C, D, and E all imply that manual intervention is required. Specifically, they suggest that administrators must provide wallet paths (B), manage server certificates (C, E), or supply encryption keys (D). Since the feature is designed to be 'set-and-forget' with auto-generated credentials handled internally by the software, these manual steps are unnecessary and incorrect.Community Comment Notes
Community consensus strongly supports Option A. Multiple users cited the official Oracle documentation for GI 19c release changes, confirming that increased security for the cluster interconnect is invoked automatically and no configuration changes are needed. One comment explicitly quoted the documentation stating that administrators do not need to make any configuration changes.Official Reference
Exam Strategy
For Oracle 19c-specific questions, look for keywords like 'automatically' or 'default'. Newer versions often introduce security features that remove manual configuration burdens, so be wary of options requiring complex manual setup unless specified otherwise.
Frequently Asked Questions
Does Secure Cluster Communication require an Oracle Wallet?
No. In GI 19c, the system handles encryption and certificates automatically. Administrators do not need to create or manage an Oracle Wallet for the cluster interconnect.
Is TLS used for the cluster interconnect in GI 19c?
Yes. Secure Cluster Communication uses Transport Layer Security (TLS) to ensure privacy and data integrity between cluster nodes automatically.
