OCI Container Registry (OCIR) is a managed Docker registry service that provides a Docker Hub equivalent functionality within Oracle Cloud Infrastructure. It allows users to store, share, and manage container images securely, making it an essential part of the infrastructure for containerized applications like those in Sunbird ED.

The SQL WHERE keyword is used to specify a condition while fetching data from a single table or by joining with multiple tables. If the given condition is satisfied, then it returns the specific value from the table.

To replay all messages in a Kafka topic using a Flink job, you would typically stop the job, reset the consumer group offset to the earliest position (often referred to as 'oldest'), and then restart the job. This process ensures that the Flink job will reprocess all messages from the beginning of the topic.

The Auto-Tiering feature in Oracle Cloud Infrastructure Object Storage is designed to optimize storage costs by automatically moving objects between the Standard and Infrequent Access tiers based on access patterns. This feature helps in reducing storage costs while ensuring that data remains accessible when needed.

Enabling Multi-Factor Authentication (MFA) is a crucial step in enhancing the security of user access to cloud services, including the Oracle Cloud Infrastructure (OCI) Console. MFA adds an additional layer of security by requiring users to provide two or more verification factors to gain access, significantly reducing the risk of unauthorized access.

Redis Cluster provides a way to run a Redis installation where data is automatically sharded across multiple Redis nodes. It's designed for horizontal scaling and high availability, which includes partitioning data across multiple nodes to enhance performance and ensure availability.

The naming conventions used in microservices often reflect their functionality. 'questionset-service' seems most aligned with the functionality one might expect in an inquiry microservice within an educational platform, handling sets of questions or inquiries.

In Oracle Cloud Infrastructure, each subnet within a VCN is associated with a single route table, not multiple route tables. Route tables contain rules to route traffic from subnets to destinations outside the VCN, and they can be used in both public and private subnets. The default routetable for a private subnet does not allow all outbound traffic to reach the Internet without specifically configured rules and an Internet Gateway or NAT Gateway.

Using the Kubernetes Cluster Autoscaler with OCI Container Engine for Kubernetes (OKE) is an effective way to dynamically adjust the resources allocated for containerized workloads based on demand. This ensures that during peak hours, additional resources are automatically provisioned to accommodate the increased load, thereby maintaining performance and availability.

The primary purpose of distributing compute instances across different Fault Domains within an availability domain is to protect against unexpected hardware failures and ensure high availability. Fault Domains provide a way to distribute instances such that they are not on the same physical hardware, reducing the risk of simultaneous failures affecting all instances.
