An MQL query for an alarm must evaluate a condition:

(CpuUtilization[1m].max() > 80).grouping().sum() (B):

CpuUtilization[1m]: Queries CPU utilization over 1-minute intervals.

.max(): Takes the maximum value per interval.

> 80: Sets a threshold (80%).

.grouping().sum(): Aggregates across metric streams, triggering the alarm if the sum exceeds 80%.This is a complete alarm query.

Why not A, C, or D?

A: Filters by shape but lacks a threshold or alarm condition.

C: Missing condition for alarming.

D: No threshold; case sensitivity doesn’t match OCI convention.

B ensures threshold-based alerting.

In OCI APM’s Synthetic Monitoring, Vantage Points are locations from which synthetic tests (e.g., HTTP requests) are run. Dedicated Vantage Points are private, user-managed instances, distinct from public ones hosted by Oracle:

Applications on-premise or on secured network cannot be tested from a public Vantage Point (B): Public Vantage Points, located in Oracle-managed regions, lack access to private networks (e.g., on-premise servers or firewalled applications). Dedicated Vantage Points, deployed within a user’s network, overcome this limitation.

Test internal customer applications (C): Dedicated Vantage Points enable testing of internal applications (e.g., intranet sites) not exposed to the public internet, ensuring performance monitoring from within the secured environment.

Why not A or D?

Test from public Vantage Point (A): Contradicts B; public Vantage Points can’t access private networks.

Test Deployment Manager and Scheduler (D): These are unrelated OCI components, not Synthetic Monitoring targets.

Dedicated Vantage Points extend monitoring to restricted environments.

APM tracks request flows using:

Using Trace ID (A): A unique identifier assigned to a trace (collection of spans) for a single user request. Propagated via HTTP headers, it links all spans across services.

Why not B or C?

User ID (B): Identifies users, not request flows.

Application Name (C): Too broad; doesn’t correlate specific requests.

Trace ID ensures end-to-end visibility in distributed systems.

The Trace Explorer in OCI Application Performance Monitoring (APM) is a tool for analyzingdistributed traces and spans. Its key functions include:

View the details of specific spans (A): Trace Explorer allows users to drill into individual spans within a trace, displaying details such as duration, status, tags, logs, and errors. This helps identify performance bottlenecks or failures in specific service calls.

Select pre-defined queries for common use cases (B): It provides built-in queries (e.g., slowest traces, error traces, traces by service) to quickly filter and analyze common scenarios, enhancing troubleshooting efficiency.

Why not C or D?

Display status of monitored systems (C): System status is monitored via OCI Monitoring or Stack Monitoring, not Trace Explorer, which focuses on traces.

Define custom metrics for traces (D): Custom metrics are defined in OCI Monitoring, not Trace Explorer, which is for viewing, not creating metrics.

Trace Explorer enhances visibility into distributed application performance.

The solution must address continuous monitoring and event-driven notifications:

D:

OCI Compute agent on on-premises VMs and OCI instances: Ensures metric continuity (e.g., CPU, memory) across the migration, using Management Agents for both environments.

Events service: Tracks launchinstance.end for deployment completion and createbucket for new buckets.

Notifications and Events: Sends email alerts for these events.

Why not A, B, or C?

A: Misses on-premises monitoring continuity.

B: Lacks bucket creation tracking.

C: Redundant 3rd-party tool use; OCI agents suffice.

D provides end-to-end coverage.

The correct OCI CLI syntax for searching logs must include the compartment, log group, log, and query:

B: oci logging-search search-logs --search-query 'search "ocid1.compartment.oc1..aaaaaaaawqegmjifhni77bqm625cxioavoq775jckfn2syxqtmglabcccdxyz/web/application" | where data.statusCode = 400' --time-start 2022-02-06T00:00:00Z --time-end 2022-02-07T00:00:00Z

Specifies the compartment OCID, web Log Group, and application Log in the scope path.

Filters for data.statusCode = 400 using proper syntax (= instead of space).

Includes valid UTC time range.

Why not A, C, or D?

A: Missing log group/log; incorrect filter syntax (400 without =).

C: No filter for status code 400.

D: Incorrect command (oci log instead of oci logging-search); redundant parameters.

B aligns with OCI Logging’s search syntax.

In OCI Logging Analytics, Log Sources are predefined parsers that extract fields from specific types of log data, enabling structured analysis.

Windows Events, Syslog Listener, and Database SQL parsers (B): These are examples of Log Sources in Logging Analytics. Each represents a specific log type with a predefined parser:

Windows Events: Parses event logs from Windows systems (e.g., security, application logs).

Syslog Listener: Handles logs in the Syslog format, common in Unix-based systems or network devices.

Database SQL parsers: Extracts fields from database logs (e.g., Oracle Database audit logs).These sources come with built-in field mappings and labels for analysis.

Why not A, C, or D?

Long, Integer, String fields (A): These are data types, not Log Sources.

File, Database, Windows Events System, Syslogs (C): While close, this mixes log locations (e.g., File, Database) with source types and isn’t a precise match to predefined Log Sources.

JSON, XML, CSV files (D): These are file formats, not Log Sources; Logging Analytics can parse them but they’re not predefined sources.

Log Sources streamline log ingestion by providing out-of-the-box parsing for common log types.

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.

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.

Management Agents collect and send data to OCI services:

Logging Analytics (B): Agents gather log data from various sources (e.g., files, databases)and send it to Logging Analytics for indexing and analysis.

Enterprise Manager (C): Agents integrate with Oracle Enterprise Manager, enabling monitoring of on-premises or cloud targets within OCI.

Why not A or D?

Application Performance Management (A): Uses Java and Browser Agents, not Management Agents.

Database Management (D): Leverages agents indirectly via other services, not a direct target.

These services leverage Management Agents for observability.
