Securing Cluster Interconnect Communication in Oracle RAC

Grid Infrastructure architecture and components

Short answer

A Secure Cluster Communication is invoked automatically during new Oracle Grid Infrastructure 19c deployments or upgrades without requiring configuration changes.

Question

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?
  1. Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c and Database administrators or cluster administrators do not need to make any configuration changes for this feature. Correct Answer
  2. Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c using an auto-generated encryption key that is stored locally on each node of the cluster in an Oracle Wallet and Database administrators or cluster administrators must provide a valid path for the Wallet file.
  3. Security for the cluster interconnect is invoked by auto-generated server certificates that will be assigned to each cluster node as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c.
  4. Database administrators or cluster administrators must provide an encryption key during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.
  5. Database administrators or cluster administrators must provide a valid server certificate and an Oracle Wallet for each node during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.

Key Takeaways

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.

Common mistake: 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.
