IBM C1000-162 Exam With Confidence Using Practice Dumps

Within IBM Security QRadar's Ariel Query Language (AQL), functions play a crucial role in manipulating data, performing calculations, and formatting results for more insightful analysis. Among the options provided, "LOWER" (C) and "STRLEN" (D) are valid AQL functions used for formatting and calculations, respectively. The "LOWER" function is used to convert a string to lowercase, which can be useful for case-insensitive comparisons or data normalization. The "STRLEN" function calculates the length of a string, providing valuable information about the data content, such as detecting unusually long or short values that might indicate anomalies or issues within the event or flow data .

Custom Properties: QRadar allows you to extract custom properties from raw log and flow data, enriching your analysis capabilities.

Supported Expression Types:

Regex (Regular Expressions): Powerful patterns for extracting specific strings or values from textual data.

JSON (JavaScript Object Notation): Extracts values from structured JSON data within events and flows.

Unsupported Types:

XLS: Excel spreadsheet format. QRadar isn't designed to parse spreadsheets directly.

YAML: A data serialization language. QRadar's extraction is more focused on data within events and flows rather than standalone configuration files.

HTML: Markup language used for web pages. Event data is unlikely to be solely in HTML format.
