Questions # 31:

Which two (2) AQL functions are used for calculations and formatting?

Options:

INCIDR

START

LOWER

STRLEN

GROUP BY

Answer

C, D

Explanation

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 .

Questions # 32:

Which type of rule should you use to test events or (lows for activities that are greater than or less than a specified range?

Options:

Behavioral rules

Anomaly rules

Custom rules

Threshold rules

Answer

Explanation

Threshold rules in QRadar are designed to test events or flows for activities that are greater than or less than a specified range. These rules are particularly useful for detecting significant changes such as bandwidth usage variations, failed services, changes in the number of connected users, and large outbound data transfers. By setting acceptable limits within threshold rules, administrators can effectively monitor for and respond to abnormal activities within the network.

Questions # 33:

A mapping of a username to a user’s manager can be stored in a Reference Table and output in a search or a report.

Which mechanism could be used to do this?

Options:

Quick Search filters can select users based on their manager’s name.

Reference Table lookup values can be accessed in an advanced search.

Reference Table lookup values can be accessed as custom event properties.

Reference Table lookup values are automatically used whenever a saved search is run.

Answer

Questions # 34:

Which log source and protocol combination delivers events to QRadar in real time?

Options:

Sophos Enterprise console via JDBC

McAfee ePolicy Orchestrator via JDBC

McAfee ePolicy Orchestrator via SNMP

Solaris Basic Security Mode (BSM) via Log File Protocol

Answer

Questions # 35:

What two (2) guidelines should you follow when you define your network hierarchy?

Options:

Do not configure a network group with more than 15 objects.

Organize your systems and networks by role or similar traffic patterns.

Use the autoupdates feature to automatically populate the network hierarchy.

Import scan results into QRadar.

Use flow data to build the asset database.

Answer

B, E

Explanation

When defining the network hierarchy in QRadar, it is recommended to organize systems and networks by role or similar traffic patterns to differentiate network behavior effectively. Additionally, it is advised not to configure a network group with more than 15 objects to avoid difficulties in viewing detailed information for each object and to ensure efficient management of network groups.

Questions # 36:

Offense chaining is based on which field that is specified in the rule?

Options:

Rule action field

Offense response field

Rule response field

Offense index field

Answer

Explanation

Offense chaining in IBM Security QRadar SIEM V7.5 is based on the offense index field specified in the rule. This means that if a rule is configured to use a specific field, such as the source IP address, as the offense index field, there will only be one offense for that specific source IP address while the offense is active. This mechanism is crucial for tracking and managing offenses efficiently within the system.

Questions # 37:

Which statement regarding saved event search criteria is true?

Options:

Saved search criteria expires

Saved search criteria does not expire

Saved search criteria cannot be reused

You cannot define the name of the saved search criteria

Answer

Explanation

In QRadar, when you save search criteria, especially on the Offenses tab, the configured search criteria are retained for future use and do not expire. This permanence ensures that users can quickly access and reuse their preferred search configurations, thereby streamlining the process of monitoring and investigating offenses over time.

Questions # 38:

Which condition is required to display the "Include in my Dashboard" parameter in the Log Activity tab while saving a search?

Options:

Filter the columns that are listed in the Available Columns list and disable the Enable Unique Counts to display the flow counts instead of average counts over Real Time

This parameter is only displayed if the search is grouped

The search must be set to Advanced Search and must be propagated with a high level of confidence

The result limits cannot be empty and not in a group

Answer

Questions # 39:

An analyst must create a reference set collection containing the IPv6 addresses of command-and-control servers in an IBM X-Force Exchange collection in order to write a rule to detect any enterprise traffic with those malicious IP addresses.

What value type should the analyst select for the reference set?

Options:

IPv6

IPv4 or IPv6

AlphaNumeric (Ignore Case)

Answer

Explanation

Specificity: The question states that the addresses are specifically IPv6-formatted. Using the 'IPv6' type ensures precision in the reference set.

IP Matching by QRadar: QRadar's rule engine will properly match against IPv6 addresses when the reference set type is 'IPv6'.

Questions # 40:

Which of these statements regarding the deletion of a generated content report is true?

Options:

Only specific reports that were not generated from the report template as well as the report template are deleted.

All reports that were generated from the report template are deleted, but the report template is retained.

All reports that were generated from the report template as well as the report template are deleted.

Only specific reports that were not generated from the report template are deleted, but the report template is retained.

Answer

Explanation

When deleting a generated content report in QRadar, all reports that were generated from the report template are deleted, but the report template itself is retained. This ensures that the structure for generating future reports remains intact, while only the instances of reports generated from that template are removed.
