You are performing maintenance on an OCI Load Balancer backend set. You want to temporarily stop sending traffic to a specific backend server without immediately dropping active persistent connections. What feature should you use?

Your organization has deployed an enterprise workload on OCI Exadata Database Service. You are configuring Data Guard with Fast-Start Failover (FSFO). To prevent split-brain scenarios where both primary and standby databases assume primary roles simultaneously, where must the Data Guard Observer be placed?

An architect is configuring Oracle Autonomous Database Disaster Recovery with cross-region Data Guard. The primary database is in Ashburn, and the standby is in Phoenix. You execute a switchover operation. What happens to the connection strings (such as tnsnames.ora entries) used by client applications?

Which OCI storage service provides massively scalable, highly durable regional object storage that is ideal for storing database backups and disaster recovery artifacts?

An OCI architect is reviewing the disaster recovery plan for a mission-critical database. The business requires a recovery drill to be executed in production without interrupting ongoing primary database operations or impacting RPO. Which Data Guard feature allows this?

Your organization uses OCI Full Stack Disaster Recovery to manage failovers between Region A and Region B. During a DR drill, you notice that a custom user-defined step failed because the dependent compute instance in Region B was not yet fully running. How should you resolve this dependency issue in the FSDR plan?
