Which HA concept applies for OAuth operations in a multi-node Kubernetes cluster?

AQuorum

BHeartbeat

CSTONITH

DQuantum

Show Suggested Answer

Suggested Answer: A

High Availability (HA) Concept: In a multi-node Kubernetes cluster, the concept of ''Quorum'' is crucial for ensuring high availability and consistency, especially for operations like OAuth.

Quorum Definition: Quorum refers to the minimum number of nodes that must agree on a transaction or operation to ensure consistency and avoid split-brain scenarios. This is particularly important in distributed systems to maintain data integrity and availability.

OAuth Operations: For OAuth operations, maintaining a quorum ensures that the authentication and authorization processes are reliable and consistent across the cluster. This helps in preventing issues where different nodes might have conflicting states.

Documentation Reference: According to the IBM Certified Solution Implementer - API Connect v10.0.3 documentation, the concept of quorum is applied to ensure high availability and consistency in OAuth operations within a multi-node Kubernetes cluster1.

Quantum? What is this, some kind of quantum computing exam? I'll have to pass on that one. Let's stick to good old-fashioned high availability practices, shall we?

STONITH? Really? That's more of a hardware-level concept. I don't think that applies here. Unless Kubernetes has secretly developed its own teleportation technology. *chuckles*

I think Heartbeat makes more sense for Kubernetes.

Definitely not STONITH, maybe Heartbeat?

Yeah, STONITH is more for hardware, not Kubernetes.

Actually, I believe the correct answer is B) Heartbeat because it ensures the availability of nodes in the cluster.

I agree with Andree, Quorum makes sense for OAuth operations in a multi-node Kubernetes cluster.

I'm not too sure about this one. Heartbeat might be a good option, but it's usually more associated with traditional HA setups. Hmm, let me think about this a bit more.
