New Release 1z0-1111-25 Oracle Cloud Infrastructure Questions

SQL Warehouse in Operations Insights categorizes SQL performance:

Degraded (A): SQL statements with declining performance over time (e.g., increased latency), indicating potential issues.

Plan changes (C): SQL statements with altered execution plans, impacting performance or resource use.

Why not B or D?

Climbing (B): Not a standard category; possibly a misnomer.

Efficient (D): Positive performance isn’t a focus category.

These help identify and resolve SQL issues.

To investigate user activity and REST API calls over the last six hours, the OCI Audit service is the appropriate tool.

Audit (E): This service automatically records all API operations (including REST API calls) performed on OCI resources. It provides detailed logs with user details, timestamps, and actions, ideal for security and compliance investigations. You can filter audit logs by time range (e.g., last six hours) and user attributes.

Why not A, B, C, or D?

Notifications (A): Sends alerts but doesn’t store or analyze API call details.

Service Connectors (B): Moves data between services, not for auditing.

Management Agent (C): Collects metrics/logs from resources, not API audit data.

Logging (D): Handles application and system logs, not API activity tracking.

Audit logs are retained for 90 days by default, making this a perfect fit.

MQL expressions in OCI Monitoring retrieve and process metric data. Optional components include:

Statistic (B): Specifies how to summarize data (e.g., avg, max). If omitted, raw data is returned.

Grouping Function (D): Aggregates data across metric streams (e.g., by resourceId). It’s optional if no grouping is needed.

Why not A, C, E, or F?

Interval (A): Defines the time window; defaults apply if omitted, but it’s typicallyrequired for meaningful queries.

Previous (C): Not a standard MQL component (possibly a typo).

Metric (E): Mandatory to specify what’s being queried.

Dimensions (F): Filters data; required if specific streams are targeted, though optional in basic queries.

Statistic and Grouping Function enhance flexibility but aren’t mandatory.

Stack Monitoring tracks application stack components:

WebLogic Servers (B): Monitors performance and health of WebLogic instances.

Oracle External Databases (C): Tracks on-premises or cloud Oracle databases outside OCI’s native DBaaS.

Why not A or D?

Object Storage Buckets (A): Not supported by Stack Monitoring; use Logging instead.

Virtual Cloud Networks (D): Network monitoring is separate (e.g., VCN Flow Logs).

These align with Stack Monitoring’s focus on application stacks.
