質問 # 22
Which Logging Analytics concept represents an asset on your host that could provide log data?
- A. Parser
- B. Association
- C. Entity
- D. Source
正解：D
解説：
Explanation
A source represents an asset on your host that could provide log data, such as a log file, a database audit log, or a Windows event log. A source defines the location, format, and frequency of the log data. You can associate a source with an entity type to enable Logging Analytics to parse and analyze the log data. For more information, see Sources.
質問 # 23
What determines the parsing options for a given source of log data in Logging Analytics?
- A. Entity Group
- B. Source-Entity Association
- C. Entity Type
- D. Entity
正解：C
解説：
Explanation
The parsing options for a given source of log data in Logging Analytics are determined by the entity type. An entity type is a predefined template that defines the attributes, log sources, and parsers for a specific type of log data, such as Apache Web Server, Oracle Database, or Linux Host. By associating an entity type with a log source, you can enable Logging Analytics to parse and extract fields from the log data. For more information, see Entity Types.

質問 # 31
Which step is essential while building a reliable log monitoring environment?
- A. Determination of the Machine Learning models you need to program
- B. Creation of the Key Performance Indicators (KPIs) to monitor
- C. Noise baseline determination
- D. Define permissions for the user roles in the region
正解：C
解説：
Explanation
An essential step while building a reliable log monitoring environment is noise baseline determination. Noise baseline is the level of noise or irrelevant log data that is present in your environment.

- D. Synthetic Monitoring
正解：D
解説：
Explanation
You would use a vantage point in Synthetic Monitoring. Synthetic Monitoring is a feature of APM that allows you to create synthetic tests to monitor the availability and performance of your web applications or APIs from different locations around the world. A vantage point is a location from where you can run synthetic tests against your target applications or APIs. A vantage point can be public or dedicated depending on your needs.
質問 # 40
Which of the following is required to enable Stack Monitoring?
- A. Dynamic group for discovery service
- B. User group for VNC collection
- C. Machine Learning group for resource associations
正解：A
解説：
Explanation
The required step to enable Stack Monitoring is to create a dynamic group for discovery service. A dynamic group is a group of OCI resources that match certain rules or criteria. You need to create a dynamic group for discovery service to allow Stack Monitoring to discover and monitor the resources in your stack. You also need to attach a policy to the dynamic group that grants the required permissions for Stack Monitoring.
質問 # 41
As a solutions architect of the Oracle Cloud Infrastructure (OCI) tenancy, you have been asked to provide members of the CloudOps group the ability to view and retrieve monitoring metrics, but only for all monitoring-enabled compute instances. Which policy statement would you define to grant this access?
- A. Allow group cloudOps to read metrics in tenancy where target.metrics.namespace-'oci_computeagent'
- B. Restricting monitoring access only to compute instancesmetrics is not possible.
- C. Allow group cloudops to read compute-metrics in tenancy
- D. Allow group cloudops to read metrics in tenancy where tar-get.metrics.monitoring='oci_computeagent'
正解：D
解説：
Explanation
To grant the CloudOps group the ability to view and retrieve monitoring metrics only for all monitoring-enabled compute instances, you need to use a policy statement with a condition that filters by the metric namespace. The metric namespace is a unique name that identifies the source of the metrics. For compute instances, the metric namespace is oci_computeagent. Therefore, the policy statement should be:
Allow group cloudops to read metrics in tenancy where target.metrics.namespace='oci_computeagent'
質問 # 42
