You must allow Sunbird ED application instances in a private subnet to download OS updates securely without assigning public IPs. Which OCI configuration is the most appropriate?

After a change window, users report intermittent authentication failures in Sunbird ED. Logs show successful connection to the identity provider, but some app nodes fail token validation. Which is the most likely root cause?

You need to store Sunbird ED configuration secrets (database password, API keys) and enable automatic rotation with auditing. Which OCI service is best suited?

Sunbird ED experiences unpredictable peak loads during national assessments. You want to scale application nodes automatically while maintaining session continuity for users. Which design is most appropriate?

You are required to ensure that only the Sunbird ED application instances can reach the database on port 1521, and no other instances in the same subnet can connect. Which control provides the most precise enforcement?

During deployment, your team wants a repeatable, auditable way to provision Sunbird ED infrastructure (VCN, subnets, load balancer, compute) across multiple environments. Which approach is most aligned with OCI best practices?

A Sunbird ED production environment must meet strict data protection requirements. You need to ensure that database backups remain accessible even if a single OCI service has an outage, while also preventing accidental deletion. Which strategy best satisfies this?

A school district is deploying Sunbird ED on OCI. They want a clear separation between public entry points and private application components, while still allowing administrators to manage private instances securely without exposing SSH/RDP to the internet. Which OCI design best meets this requirement?

In a Sunbird ED deployment, users report intermittent login failures. The application logs show occasional timeouts when calling a backend microservice. The load balancer health check is currently configured to probe only the TCP port. What is the most appropriate improvement?

Your team needs Sunbird ED audit logs retained and searchable for incident investigations. They want to track who changed IAM policies and who modified networking components. Which OCI capability directly provides these records?

A Sunbird ED environment uses Object Storage for storing exported reports. The security team requires that objects cannot be deleted or overwritten for a defined retention period, even by administrators. What should you implement?

You must deploy Sunbird ED across separate OCI compartments for networking, security, and application teams. The application team needs to read secrets from OCI Vault but must not be able to create or delete vaults. Which IAM approach is most appropriate?

A Sunbird ED deployment uses private subnets. Instances need to download OS patches and reach OCI public services without being reachable from the internet. Which networking component should you add?

After scaling out Sunbird ED application instances behind an OCI Load Balancer, you notice some users intermittently lose session state during navigation. The application is not designed to be stateless yet. Which load balancer feature most directly addresses this symptom?

A Sunbird ED production deployment must meet strict requirements: (1) only private connectivity from on-premises to the application, (2) no public IPs on any tier, and (3) access to Object Storage for exports must not traverse the public internet. Which combination of OCI components best satisfies all requirements?

You are designing Sunbird ED for high availability across fault domains and want to minimize blast radius during maintenance.
