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 route table 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.

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.

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.

Discourse is a popular, modern, open-source discussion platform known for its robustness and

flexibility. It is often chosen for community forums due to its extensive features, such as real-time

updates, comprehensive moderation tools, and ease of integration, making it a suitable choice for

platforms like Sunbird that require interactive and engaging discussion forums.

Oracle Cloud Agent collects various performance metrics from compute instances, such as Disk Read

I/O, Memory Utilization, and CPU Utilization, to help monitor and manage the performance of

instances. However, Disk Free Space is typically not a metric directly provided by the Oracle Cloud

Agent as it focuses more on performance metrics rather than storage capacity metrics.

To allow members of the NetworkAdmins group to create and configure Virtual Cloud Network (VCN)

components within the Project-A compartment, the policy statement should provide 'manage'

privileges to the 'virtual-network-family' in that compartment. This allows the group to perform all

actions within the virtual network resource family, including creation and configuration.

Compartments in Oracle Cloud Infrastructure are used to logically organize and isolate OCI resources.

They provide a way to separate resources for different projects or departments and control access

through policies, aligning with governance and business requirements.

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 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.

In microservices and distributed systems, caches are often used to improve performance. The

command 'sync-rel-cache-all' suggests a process to synchronize and regenerate the cache for

collection relationships, which is a plausible approach to constructing or reconstructing a cache in

such systems.
