Question 1

A Behavioral Threat Protection (BTP) alert is triggered with an action of "Prevented (Blocked)" on one of several application servers running Windows Server 2022. The investigation determines the involved processes to be legitimate core OS binaries, and the description from the triggered BTP rule is an acceptable risk for the company to allow the same activity in the future.

This type of activity is only expected on the endpoints that are members of the endpoint group "AppServers," which already has a separate prevention policy rule with an exceptions profile named "Exceptions-AppServers" and a malware profile named "Malware-AppServers."

The CGO that was terminated has the following properties:

SHA256: eb71ea69dd19f728ab9240565e8c7efb59821e19e3788e289301e1e74940c208

File path: C:\Windows\System32\cmd.exe

Digital Signer: Microsoft Corporation

How should the exception be created so that it is scoped as narrowly as possible to minimize the security gap?

ACreate the exception via the alert itself, selecting the CGO hash, CGO signer, CGO process path, and applying the scope to the 'Exceptions-AppServers' profile.

BCreate a Disable Prevention Rule via Exceptions Configuration with the following selections:

CCreate a Legacy Agent Exception via Exceptions Configuration with the following selections:

DCreate the exception via the alert itself, selecting the CGO hash, CGO signer, CGO process path, and applying the scope to 'Global.'

Answer : B

The most secure approach is to create a Disable Prevention Rule via Exceptions Configuration, scoped specifically to the Exceptions-AppServers profile. This rule should include the hash (SHA256), signer (Microsoft Corporation), and file path (C:\Windows\System32\cmd.exe). This ensures the exception is applied only to the trusted, legitimate process on the AppServers group while minimizing the security gap.

Question 2

A Cortex XSIAM engineer is developing a playbook that uses reputation commands such as '!ip' to enrich and analyze indicators.

Which statement applies to the use of reputation commands in this scenario?

AIf no reputation integration instance is configured, the '!ip' command will execute but will return no results.

BReputation commands such as '!ip' will fail if the required reputation integration instance is not configured and enabled.

CThe mapping flow for enrichment commands is disabled if extraction is set to 'None.'

DEnrichment data will not be saved to the indicator unless the extraction setting is manually configured in the playbook task.

Answer : B

Reputation commands such as !ip rely on a configured and enabled reputation integration instance (for example, VirusTotal, Palo Alto WildFire, or other threat intel sources). If no such instance is available, the command execution will fail, since it cannot retrieve enrichment data.

Question 3

How will Cortex XSIAM help with raw log ingestion from third-party sources in an existing infrastructure?

AAny structured logs coming into it are left completely unchanged, and only metadata is added to the raw data.

BFor structured logs, like CEF, LEEF, and JSON, it decouples the key-value pairs and saves them in table format.

CAny unstructured logs coming into it are left completely unchanged, and metadata is not added to the raw data.

DFor unstructured logs, it decouples the key-value pairs and saves them in a table format.

Answer : B

Cortex XSIAM ingests structured third-party logs (such as CEF, LEEF, and JSON) by breaking down the key-value pairs and saving them in a normalized table format. This enables efficient correlation, analytics, and query performance across diverse log sources while preserving data fidelity.

Question 4

What is a key characteristic of a parsing rule in Cortex XSIAM?

AIt uses regular expressions exclusively for data modifications, discards unmatched logs by default, and only retains fields with non-null values.

BIt is bound to all vendors and products, performs data parsing once per log, and does not allow grouping.

CIt is bound to a specific vendor and product, performs data parsing once per log, and does not allow grouping.

DIt is bound to a specific vendor and product which allow grouping with a no-match policy, and retains all fields.

Answer : C

A parsing rule in Cortex XSIAM is bound to a specific vendor and product, ensuring accurate parsing logic for that log source. It processes each log individually (once per log) and does not allow grouping, making it distinct from data model rules.

Question 5

A Cortex XSIAM engineer is preparing to install a new content pack and notices that there are several optional content packs associated with the main one that needs to be installed.

What must the engineer take into consideration when deciding whether or not to install the optional content packs?

AMandatory dependencies required by the optional content packs are automatically included during installation. The engineer should consider the additional functionality and potential impact on system performance.

BThe optional content packs without their associated dependencies are installed first, and then the main content pack installation is triggered. The engineer should ensure that the optional content packs do not conflict with existing configurations.

COptional content packs are installed without any dependencies, as they are not necessary. The engineer should only install them if they require the additional features.

DOnly the selected optional content packs are installed, without including any additional dependencies. The engineer should manually check for any required dependencies.

Answer : A

When installing optional content packs in Cortex XSIAM, any mandatory dependencies are automatically included. The engineer's main consideration is whether the additional functionality is needed and whether it may have a performance impact on the system.

Question 6

Administrators from Building 3 have been added to Cortex XSIAM to perform limited functions on a subset of endpoints. Custom roles have been created and applied to the administrators to limit their permissions, but their access should also be constrained through the principle of least privilege according to the endpoints they are allowed to manage. All endpoints are part of an endpoint group named "Building3," and some endpoints may also be members of other endpoint groups.

Which technical control will restrict the ability of the administrators to manage endpoints outside of their area of responsibility, while maintaining visibility to Building 3's endpoints?

ASBAC enabled in Building 3's IP range with the 'EG:Building3' tag assigned to each administrator's scope

BSBAC enabled in Permissive Mode with the 'EG:Building3' tag assigned to each administrator's scope

CSBAC enabled in Restrictive Mode with the 'EG:Building3' tag assigned to each administrator's scope

DSBAC enabled globally with the 'EG:Building3' tag assigned to each administrator's scope

Answer : C

To enforce least privilege for Building 3 administrators, SBAC must be enabled in Restrictive Mode and the administrators' scope must be limited to EG:Building3. This ensures they can only manage endpoints within the Building 3 group, even if those endpoints are also part of other groups, while blocking access to endpoints outside their responsibility.

Question 7

What should be considered when creating a custom incident domain?

AAlert grouping will not apply, but SmartScore will.

BAlert grouping will apply, but SmartScore will not.

CAlert grouping and SmartScore will not be applied to incidents.

DAlert grouping and SmartScore will be applied to incidents.

Answer : B

When creating a custom incident domain in Cortex XSIAM, alert grouping still applies, allowing related alerts to be combined into incidents. However, SmartScore is not applied, since it is reserved for predefined domains.
