Oracle Cloud Infrastructure 2025 Observability Professional Practice Exam 2025: Latest Questions

You want to monitor CPU utilization for a fleet of OCI compute instances and view the trend over the last 24 hours in the Console. Which OCI Observability feature is primarily used to query and visualize these time-series values?

A security team wants all audit events to be retained and searchable in a central location for investigations. Which OCI service and log type should you use to meet this requirement with minimal configuration?

You need to notify an on-call engineer when an OCI alarm transitions to FIRING. Which OCI component is responsible for delivering the alarm message to endpoints such as email, SMS, or a webhook?

An application team wants to quickly identify which service call is causing slow end-to-end transaction times in a distributed microservices architecture. Which APM capability is most directly used to see the breakdown across services?

You are building a dashboard that shows error rate by service. Application teams want to tag each metric with environment (prod/dev) and serviceName to filter and group results. What is the recommended approach in OCI Monitoring?

A team ingests application logs into OCI Logging. They want to run advanced searches, create dashboards on extracted fields, and perform aggregations over time (for example, count of 5xx errors by client IP). Which service best fits this requirement?

An operations team created an alarm on a high-volume metric and receives frequent notifications during brief spikes, causing alert fatigue. They still want to be notified when the issue persists. Which alarm configuration change is most appropriate?

Users report intermittent timeouts. APM shows that overall response time increases, but you need to determine whether latency is in the application code or in downstream database calls. Which APM view or telemetry should you use first to isolate where time is spent?

You must route logs from multiple compartments to a centralized log analytics compartment while ensuring teams can still access their own raw logs in their source compartments. What design best meets this requirement with least operational overhead?

An alarm based on a custom metric never fires, even though you see values on a dashboard. The alarm query uses a different compartment than where the metric is emitted. Which is the most likely cause and fix?

You need to quickly determine whether an OCI Compute instance is experiencing CPU saturation using built-in observability features. Which metric is the most direct indicator to check first?

A team wants to centrally store and search all service logs from multiple OCI resources (Load Balancer, API Gateway, Functions) using a consistent approach. Which OCI feature should they use to route these logs into a common destination for querying?

You created an OCI alarm that should notify on-call engineers when triggered. Which OCI service is the alarm typically configured to publish to so that multiple subscription endpoints (email, HTTPS, PagerDuty bridge) can receive the alert?

A security team needs to identify the top 20 source IPs generating failed login attempts across hundreds of Linux instances. They want to normalize and query the logs at scale and build dashboards. Which approach best meets this requirement?

An alarm based on a metric is not firing even though the console graph shows metric data points. The metric appears in a different compartment than the alarm. What is the most likely reason?

You are instrumenting a microservices application for distributed tracing. The goal is to follow a single user request across multiple services and see end-to-end latency contributions. Which APM concept is primarily responsible for linking the operations across services?

A platform team wants to route VCN Flow Logs and Load Balancer access logs into a central analytics solution and also retain raw copies in Object Storage for compliance. What is the most appropriate OCI design?

An on-call engineer wants an alarm that triggers only when error rate is high AND request volume is significant, to avoid alerting during low-traffic periods. What is the best approach in OCI Monitoring?

After deploying APM, you see traces for a service but database calls are missing, making it hard to identify whether latency is caused by SQL execution. The application uses a JDBC client and runs on a supported platform. Which is the most likely cause?

Your organization needs to ensure that only a subset of administrators can modify alarm definitions, while a broader group can view alarm status and history. Which OCI approach best enforces this separation of duties?

You manage a fleet of compute instances. You want to alert only when an instance is unreachable from the OCI monitoring plane (for example, network path or agent health issues), not when CPU or memory is high. Which metric-based approach best fits this requirement?

A platform team wants developers to query logs across many compartments using a consistent tag-based filter (for example, Environment=Prod) without granting broad access to read all resources in those compartments. What is the recommended OCI Logging/Log Analytics design approach?

You configured an OCI alarm that should notify an Operations team email address. The alarm state changes to FIRING, but no one receives email. The Notifications topic shows multiple undelivered messages. What is the MOST likely cause?

An application instrumented with OCI APM shows high end-to-end latency. APM traces indicate the slowest segment is an outbound call to a database service, but the database team claims the DB is healthy. What is the BEST next step in OCI Observability to isolate whether the issue is network-related versus database execution time?

You need an alarm that triggers when error logs exceed a threshold (for example, more than 50 "ERROR" entries in 5 minutes) for a set of microservices. Which approach is MOST appropriate in OCI Observability?
