The minimum bandwidth for a flexible load balancer in OCI is 10 Mbps. This allows for granular control over the load balancer's capacity, enabling it to be precisely tailored to the application's needs, such as the Player microservice in Sunbird ED Portal, ensuring efficient distribution of traffic and optimal resource utilization.

In Angular's@NgModuledecorator, thedeclarationsarray is used to make directives (including components and pipes) from the current module available to other directives in the current module. Services are typically provided in theprovidersarray of@NgModuleor a component's@Componentdecorator, not indeclarations.

Grafana is a popular open-source platform for monitoring and observability, widely used for real-time data visualization with support for various data sources, including cloud services and databases, making it an ideal choice for real-time monitoring and visualization of key performance metrics.

For a knowledge microservice, a combination of Neo4J, Cassandra, and Cloud Storage would provide a robust solution. Neo4J offers graph database capabilities for complex queries andrelationships, Cassandra provides scalable and high-performance data management, and Cloud Storage offers a flexible solution for storing large amounts of unstructured data.

The 'inQuiry' module or component within the Sunbird platform logically aligns with the functionality related to questions and question sets. This module is likely responsible forhandling workflows and processes related to creating, managing, and using questions and question sets in educational content or assessments.

In Oracle Cloud Infrastructure (OCI) IAM, the principle of least privilege is applied, which means that access to resources is denied by default. Users and groups are granted access explicitly through policies that define the actions allowed on specific resources, ensuring that access is controlled and minimized to what is necessary.

'oci-local-vcn' is not a valid source CIDR for a security list rule in Oracle Cloud Infrastructure VCNs. Security list rules are configured using CIDR notation to specify allowed or denied IP address ranges for ingress and egress traffic. Valid CIDR notations include specific IP ranges like '0.0.0.0/0', '10.0.1.0/24', and '192.168.1.0/24'.
