Correct Answers: B and D
Microsoft Azure Monitor stores two types of data: logs and metrics. This data helps users to monitor, tune and troubleshoot their applications and services. Azure Monitor collects data from applications, operating systems, Azure resources, subscriptions, tenants, and custom sources.
Logs data are the records that contain predominantly text information but can include numeric data as well. Typically logs store event information from a variety of sources. Azure Monitor creates a table for each log source to store its data and uses Log Analytics workspace as a data storage. You can use Azure Monitor tools or Azure Data Explorer to query logs data with the help of Kusto Query Language (KQL).
Metrics data is numeric information that you can collect from services such as Application Insights. It includes metric telemetry data like request rates, response times, performance counters, etc. This type of data is collected in the Metric part of the Azure Monitor. The structure of the Metric data differs from the Log Analytics data. Metric data is stored in time-series databases. These databases are optimized for analyzing time-stamped data. To work with Metric data, you can use Azure Metrics Explorer or other tools to analyze telemetry data details, like Application maps, Profiler, Dashboards, etc.
All other options are incorrect.
