A financial services company is using OCI Resource Manager to deploy a complex, multi-VCN architecture. The lead DevOps engineer needs to ensure that sensitive outputs, such as a database administrator's initial password, are not displayed in the stack's log files or stored in the state file in plain text. Which Terraform language feature should be used in the configuration to achieve this?
An operations team is managing a large fleet of compute instances across several compartments. They need to retrieve a list of all instances that are tagged with `"environment"="production"` but only display their OCID, display name, and lifecycle state. Which OCI CLI command correctly accomplishes this using a JMESPath query?
A cloud engineer is writing an Ansible playbook to automate the patching of a fleet of Oracle Linux instances in OCI. The playbook needs to connect to the instances, apply the latest security patches using `yum`, and then reboot the instance only if a kernel update was applied. Which TWO Ansible modules are essential for this task? (Select TWO)
A startup is deploying a new application on OCI compute instances and wants to automate the installation of their monitoring agent and the configuration of the firewall upon first boot. The configuration steps are identical for all instances and are defined in a shell script stored in an OCI Object Storage bucket. What is the most efficient method to execute this script using cloud-init?
A media company is experiencing significant cost overruns in their OCI tenancy, primarily related to Object Storage. The finance department wants to understand which specific department, identified by a cost-tracking tag named `Department`, is responsible for the majority of storage costs over the last quarter. How can a Cloud Ops professional generate this report using the Cost Analysis tool?
An e-commerce platform runs its primary database on a high-performance compute instance with a 1 TB block volume. During peak sales events, the database experiences I/O bottlenecks, leading to slow transaction times. The current block volume is set to the 'Balanced' performance level. What is the most effective and immediate action to mitigate the I/O bottleneck without causing downtime for the database?
True or False: A compartment quota policy, once set, prevents users from creating any new resources in that compartment if any one of the specified limits in the policy statement is reached.
A global logistics company is designing a highly available application on OCI. The application consists of a web tier running on an instance pool. To ensure resilience and responsiveness, the application must automatically scale out when CPU utilization averages above 70% for 5 minutes, and scale in when it drops below 30% for 10 minutes. Which OCI service is used to define these specific scaling triggers?
A healthcare provider needs to implement a robust disaster recovery (DR) plan for their critical patient data stored in an OCI Block Volume. The Recovery Point Objective (RPO) is 1 hour, and the Recovery Time Objective (RTO) is 4 hours. The primary region is US East (Ashburn) and the DR region is US West (Phoenix). Which OCI feature should be implemented to meet these DR requirements?
A retail company uses OCI Object Storage to store transaction logs. For compliance reasons, logs must be retained for 7 years. However, they only need to be accessed frequently for the first 30 days. After 30 days, they should be moved to a more cost-effective storage tier, and after one year, they should be moved to the most cost-effective long-term storage. Which OCI mechanism automates this process?
