Important Oracle 1Z0-1111-25 Exam Questions

Answer: A

Explanation:

To enable Stack Monitoring:

Dynamic group for discovery service (A): A dynamic group defines resources (e.g., compute instances) that Stack Monitoring can discover and monitor. A policy granting permissions to this group is also required.

Why not B or C?

Machine Learning group (B): Not a valid OCI concept for Stack Monitoring.

User group for VCN collection (C): User groups manage human access, not service discovery.

This setup ensures Stack Monitoring can access and monitor resources.

Answer: D

Explanation:

APM uses specific metric namespaces to categorize its telemetry data:

oracle_apm_rum, oracle_apm_synthetics, and oracle_apm_monitoring (D):

oracle_apm_rum: Metrics from Real User Monitoring (e.g., page load times).

oracle_apm_synthetics: Metrics from Synthetic Monitoring (e.g., test response times).

oracle_apm_monitoring: Metrics from distributed tracing (e.g., span counts).

These namespaces align with APM's three core features.

Why not A, B, or C?

A: Individual metric names, not namespaces.

B: Incomplete and incorrect namespace naming.

C: Mixes metric types with partial namespace names.

These namespaces enable targeted metric queries in OCI Monitoring.

Answer: C, D

Explanation:

Database Management Service provides advanced database oversight:

Compare database performance across different time periods or perform real-time monitoring of SQL statements (C): Uses Performance Hub for historical and real-time SQL monitoring.

Analyze and tune SQL performance issues of Oracle Databases on-premises, OCI, and multi-cloud environments (D): Offers SQL tuning across diverse deployments.

Why not A or B?

A and B: Capacity forecasting is an Operations Insights feature, not Database Management.

These actions enhance database performance management.

Answer: A, B

Explanation:

The OCI Events Service enables event-driven automation by reacting to changes in OCI resources. Two valid use cases are:

Process files when they are uploaded in an Object Storage bucket (A): You can create an event rule to trigger an action (e.g., invoking an Oracle Function) when an object is created (com.oraclecloud.objectstorage.createobject). The function could process the file (e.g., image resizing).

Perform cleanup tasks when an OCI resource is terminated (B): An event rule can detect resource termination (e.g., com.oraclecloud.computeapi.terminateinstance.end) and trigger a function to clean up associated resources (e.g., delete volumes).

Why not C or D?

Migrate Events (C): Events Service doesn't ''migrate'' events; it triggers actions. Migration is more aligned with Service Connector Hub.

Configuration management (D): This is handled by services like Resource Manager or Ansible, not Events Service.

These use cases showcase the service's ability to automate workflows based on resource state changes.

Answer: B, C

Explanation:

The Database Management Service enhances database oversight:

Monitor database performance (B): Provides tools like Performance Hub to track real-time and historical metrics (e.g., CPU, I/O).

Perform management tasks across a group of databases (C): Database Fleet Management enables bulk operations (e.g., configuration checks, SQL execution) across multiple databases.

Why not A or D?

A: Log viewing is via Logging Service, not a core DM feature.

D: SQL analysis is in Operations Insights, not DM directly.

These capabilities streamline database administration.
