Oracle Cloud Infrastructure 2025 Observability Professional Intermediate Practice Exam: Medium Difficulty 2025

A DevOps team is monitoring a multi-tier application running on OCI Compute instances. They need to create a custom metric that tracks the number of active database connections per instance and trigger an alarm when connections exceed 80% of the maximum allowed. The metric data should be available for analysis for 90 days. What is the correct approach to implement this solution?

An organization is implementing centralized logging for their OCI infrastructure. They have VCN Flow Logs, Load Balancer access logs, and application logs from 50 Compute instances across multiple compartments. They need to correlate events across these sources and retain logs for compliance purposes for 1 year. What is the most appropriate solution?

A company has configured an alarm in OCI Monitoring to detect when CPU utilization exceeds 85% on their production database servers. The alarm is triggering notifications via the Notifications service, but the operations team reports they are receiving alerts for brief, non-critical spikes that resolve within seconds. What configuration change would best address this issue while still catching sustained high CPU conditions?

A microservices application deployed on OCI Container Engine for Kubernetes (OKE) is experiencing intermittent latency issues. The development team needs to identify which service in the call chain is causing delays and understand the dependencies between services. Which OCI Observability service and approach should they use?

An operations team needs to monitor critical business metrics derived from application logs stored in Log Analytics. They want to create alarms that trigger when the number of failed transaction logs exceeds 50 occurrences within a 5-minute window. What is the correct approach to implement this requirement?

A company has multiple OCI regions with resources distributed globally. They need to implement a centralized monitoring solution where alarms from all regions trigger notifications to a single operations team. The team wants to receive notifications via email, Slack, and PagerDuty based on alarm severity. What is the most effective architecture to achieve this?

A data engineering team is using Log Analytics to analyze application logs and has created several complex queries for different dashboards. They notice that similar queries take significantly different amounts of time to execute. Which factors most significantly impact Log Analytics query performance, and what optimization strategies should they implement?

An e-commerce application running on OCI is experiencing performance degradation during peak hours. The APM service shows increased response times, but the team needs to understand if the issue is caused by database queries, external API calls, or application code execution. What APM features and analysis approach should they use to identify the root cause?

A company wants to monitor their OCI Autonomous Database instances and create alarms for high CPU usage and storage consumption. They also need to track custom application-level metrics like transaction throughput. How should they architect their monitoring solution to meet both infrastructure and application monitoring requirements?

A security team needs to monitor and alert on specific patterns in OCI Audit logs, such as unauthorized access attempts, resource deletions, and policy changes across all compartments in their tenancy. They need to retain audit data for 2 years for compliance. What is the best approach to implement this monitoring and retention strategy?
