Oracle Cloud Infrastructure for Sunbird ED Specialty Practice Exam 2025: Latest Questions

In a Sunbird ED on OCI deployment, which component is primarily responsible for routing user requests to the appropriate application instances while enabling high availability?

You are setting up OCI networking for Sunbird ED. The application servers must not be directly reachable from the internet, but they must still download OS updates from external repositories. What is the recommended approach?

Sunbird ED is configured to store and serve user-uploaded content. Which OCI service is best suited as a durable, highly available object store for this content?

You need to rotate a database password used by Sunbird ED without placing secrets in instance boot scripts or source control. Which OCI capability is the best fit?

After deploying Sunbird ED, users report intermittent timeouts during peak usage. The application tier is deployed on multiple compute instances behind an OCI Load Balancer. Which change is MOST likely to improve resiliency and reduce timeouts without modifying application code?

A Sunbird ED deployment requires private access from application instances to OCI Object Storage without traversing the public internet. What should you configure in the VCN?

Your operations team wants to centralize logs from Sunbird ED compute instances (system logs and application logs) to search and troubleshoot issues across the fleet. Which OCI approach is most appropriate?

A Sunbird ED environment must enforce least-privilege access: developers can restart application instances but cannot modify networking or IAM policies. Which OCI capability best addresses this requirement?

You are designing a highly available Sunbird ED deployment across multiple Availability Domains (ADs). The database layer must tolerate the loss of an AD with minimal data loss and automatic failover. Which option best fits this requirement on OCI?

After a routine security hardening change, Sunbird ED application instances in a private subnet can no longer reach the database on the database subnet. Both subnets are in the same VCN. Ping is not allowed. Which is the MOST likely root cause to check first in OCI?

A new administrator needs to quickly verify that a Sunbird ED deployment can reach required OCI services without opening the VCN to the public internet. Which approach best meets this requirement?

During a Sunbird ED rollout, you want to ensure API keys for OCI access are never stored on compute instances. What is the best OCI service to store and manage sensitive material such as keys and secrets?

A Sunbird ED operator needs to confirm whether a failed deployment step was caused by an OCI Identity policy denying access to a resource. Where should they look first for authoritative evidence of an authorization failure?

A Sunbird ED environment is deployed across two availability domains for resilience. Users intermittently report slow responses only when their requests are served by instances in the second AD. Which troubleshooting step is MOST likely to identify the root cause at the infrastructure level?

Your Sunbird ED deployment includes a stateless API tier running on multiple instances. You must perform a rolling update with minimal downtime and ensure traffic is only sent to healthy instances. Which OCI capability best supports this requirement?

A platform team wants to enforce a standard, repeatable Sunbird ED infrastructure deployment across multiple compartments. They also want change history and peer review. Which approach is MOST aligned with OCI best practices?

Sunbird ED requires access to Object Storage for backups. Security policy mandates that data must not traverse the public internet, and egress should be restricted to only required OCI services. Which network design best meets these requirements?

A Sunbird ED microservice running on OCI Compute cannot connect to a managed database on a private subnet. Security lists allow the port, and the route tables look correct. Connectivity works from one subnet but not another. What is the MOST likely missing configuration?

A Sunbird ED production environment must remain available if an entire availability domain becomes unavailable. The application uses persistent data that must be recoverable with minimal data loss. Which design is MOST appropriate?

A security team requires that only a dedicated CI/CD service can deploy changes to Sunbird ED resources, and human administrators must not have long-lived broad permissions. Which OCI IAM pattern best satisfies this requirement?

A university is deploying Sunbird ED on OCI and wants to ensure the application servers can reach OCI services (Object Storage, Logging, Monitoring) without traversing the public internet. The VCN already has private subnets for the application tier. What is the recommended approach?

After deploying Sunbird ED, administrators report intermittent login failures and slower response times during peak hours. You suspect the load balancer is distributing traffic across instances, but unhealthy instances are still receiving requests. What OCI feature should you verify and tune first to address this?

A Sunbird ED deployment must store user-generated content and documents durably and make them accessible to multiple application instances across availability domains. The team also wants to enable server-side encryption and avoid managing file servers. Which OCI service best fits these requirements?

Security policy requires that Sunbird ED application instances cannot have SSH access from the internet. Administrators must still perform occasional OS patching and troubleshooting. Which approach best meets the requirement while following OCI best practices?

A Sunbird ED environment uses private subnets and a NAT Gateway for outbound access. Application instances fail to download OS updates from public repositories, but they can still access Object Storage through a Service Gateway. The security lists are permissive for egress, and the NAT Gateway exists. What is the MOST likely cause?
