5V0-93.22 Practice Exam Questions with Answers VMware Carbon Black Cloud Endpoint Standard Skills Certification

The correct statement regarding Blocking/Isolation rules and Permission rules is D. Blocking & Isolation rules are overridden by Permission Rules. This means that if a file or process matches both a Blocking/Isolation rule and a Permission rule, the action specified by the Permission rule will take precedence over the action specified by the Blocking/Isolation rule. For example, if a file has a reputation of SUSPECT_MALWARE and a Blocking/Isolation rule is set to terminate any SUSPECT_MALWARE file that runs, but a Permission rule is set to allow and log any file that runs from a specific path, the file will be allowed and logged if it runs from that path, regardless of its reputation. Permission rules are useful for tuning the behavior of VMware Carbon Black Cloud Endpoint Standard and preventing false positives or unnecessary blocks1.

The other statements are false or irrelevant. Blocking & Isolation rules are not overridden by Upload Rules. Upload Rules are rules that specify which files and metadata are uploaded to the Carbon Black Cloud for analysis and reputation. Upload Rules do not affect the prevention or detection capabilities of VMware Carbon Black Cloud Endpoint Standard2. Permission Rules are not overridden by Blocking & Isolation rules. As explained above, Permission Rules have a higher priority than Blocking & Isolation rules and can override their actions. Upload Rules are not overridden by Blocking & Isolation rules. Upload Rules and Blocking & Isolation rules are independent of each other and do not affect each other’s functionality. References:

• Prevention Policy Settings - VMware Docs, Permissions section, Action subsection.
• Upload Rules - VMware Docs, Overview section.

The impact of using the wildcards in the path for this rule is C. Any executable in the downloads directory for any user on the system will be bypassed for inspection. This is because the permission rule has the following options selected:

• Application at path: C:\Users*\Downloads**
• Operation Attempt: Performs any operation
• Action: Bypass

The application at path field specifies the path of the executable file that the rule applies to. The * wildcard matches 0 or more consecutive characters up to a single subdirectory level. For example, C:\Users*\ matches any subdirectory under the Users directory, such as C:\Users\Lorie, C:\Users\John, or C:\Users\Alice. The ** wildcard matches a partial path across all subdirectory levels and is recursive. For example, \Downloads** matches any files in that directory and all subdirectories. Therefore, by using the wildcards in the application at path field, the permission rule covers any executable file in the downloads directory for any user on the system.

The operation attempt field specifies the type of operation that the executable file attempts to perform. The Performs any operation option means that the rule applies to any operation, such as creating a file, modifying a registry key, or executing a command.

The action field specifies the action that the VMware Carbon Black Cloud Endpoint Standard sensor takes when the rule is triggered. The Bypass option means that the sensor ignores the executable file and does not apply any blocking rules or log any events for it1.

Therefore, by using the wildcards in the path for this rule, the permission rule effectively bypasses any executable file in the downloads directory for any user on the system from the VMware Carbon Black Cloud Endpoint Standard sensor’s prevention and detection capabilities. References:

• Prevention Policy Settings - VMware Docs, Permissions section, Action subsection.

This feature allows the administrator to test the rule against historical data and see how many events would have matched the rule criteria in the past 24 hours. The administrator can also see the details of the matching events, such as the device name, the process name, the process path, the operation type, and the operation result. This feature can help the administrator to confirm that the new rulewould have prevented a previous execution that had been observed, as well as to evaluate the effectiveness and accuracy of the rule1.

The other options are not features that can be used for this purpose. A. Setting up a notification based on a policy action, and then selecting Terminate is a feature that allows the administrator to receive an alert when a terminate rule is triggered by a current event, but it does not allow the administrator to test the rule against historical data. C. Configuring the rule to terminate the process is a feature that allows the administrator to specify the action that the sensor will take when the rule is triggered by a current event, but it does not allow the administrator to test the rule against historical data. D. Configuring the rule to deny operation of the process is a feature that allows the administrator to specify a different action than terminate for the rule, but it does not allow the administrator to test the rule against historical data. References:

The VMware Carbon Black sensor uses port 443 by default to communicate with the VMware Carbon Black Cloud. This port is used for both incoming and outgoing TCP connections to the environment-specific URLs that provide console access, API requests, sensor communication, UBS download, signature update, third-party certificate validation, and Live Response uploads. Port 54443 is used as a backup port in case port 443 is blocked or unavailable. Ports 80 and 22 are not used by the VMware Carbon Black sensor. References: Configure a Firewall, Ports and URLs

 The Investigate page in the VMware Carbon Black Cloud Endpoint Standard console is where the security administrator can perform a search to further inspect the script-based attack that was coded into Excel VBA. The Investigate page allows the administrator to use advanced search techniques to query the endpoint data collected by the VMware Carbon Black Cloud sensors. The administrator can use various fields and operators to filter and refine the search results, such as process_name, file_name, file_path, file_type, file_description, and more. The administrator can also use the processtree view to visualize the process execution and the event details to examine the process activity. For example, the administrator can use the following search query to find all the processes that have a file type of Excel VBA:

file_type:EXCEL_VBA

This query will return all the processes that have a file type of EXCEL_VBA, which is a file type that indicates the file contains Excel VBA code. The file_type field is a string that indicates the type of the file based on its content and format. The possible values for this field are:

• EXE: Executable file
• DLL: Dynamic-link library file
• SYS: System file
• BAT: Batch file
• CMD: Command file
• VBS: Visual Basic Script file
• JS: JavaScript file
• PS1: PowerShell Script file
• HTA: HTML Application file
• MSI: Windows Installer file
• DOC: Microsoft Word document file
• XLS: Microsoft Excel spreadsheet file
• PPT: Microsoft PowerPoint presentation file
• PDF: Portable Document Format file
• SWF: Shockwave Flash file
• JAR: Java Archive file
• CLASS: Java class file
• PY: Python script file
• SH: Shell script file
• PL: Perl script file
• RB: Ruby script file
• PHP: PHP script file
• ASP: Active Server Pages file
• ASPX: Active Server Pages Extended file
• HTML: HyperText Markup Language file
• XML: Extensible Markup Language file
• DOCM: Microsoft Word document with macros file
• XLAM: Microsoft Excel add-in with macros file
• XLSM: Microsoft Excel spreadsheet with macros file
• XLTM: Microsoft Excel template with macros file
• PPTM: Microsoft PowerPoint presentation with macros file
• POTM: Microsoft PowerPoint template with macros file
• PPAM: Microsoft PowerPoint add-in with macros file
• EXCEL_VBA: Excel Visual Basic for Applications file
• WORD_VBA: Word Visual Basic for Applications file
• POWERPOINT_VBA: PowerPoint Visual Basic for Applications file
• OUTLOOK_VBA: Outlook Visual Basic for Applications file
• ACCESS_VBA: Access Visual Basic for Applications file

• VISIO_VBA: Visio Visual Basic for Applications file
• PUBLISHER_VBA: Publisher Visual Basic for Applications file
• INFOPATH_VBA: InfoPath Visual Basic for Applications file
• ONENOTE_VBA: OneNote Visual Basic for Applications file
• UNKNOWN: Unknown file type

Therefore, by using the Investigate page in the VMware Carbon Black Cloud Endpoint Standard console, the security administrator can perform a search to further inspect the script-based attack that was coded into Excel VBA. References:

According to the VMware Carbon Black Cloud Sensor Installation Guide, the permission level that is required when a user wants to install a sensor on a Windows endpoint is Administrator. The usermust have local administrator privileges on the endpoint to install the sensor. The user can install the sensor by using one of the following methods:

• Method 1: Invite Users to Install Sensors on Endpoints: This method allows the user to install the sensor by using an installation code that is sent by email from the Carbon Black Cloud console. The user must run the installation code as an administrator on the endpoint.
• Method 2: Install the Sensor on the Endpoint by using the Command Line or Software Distribution Tools: This method allows the user to install the sensor by using the command line, or by using a scripted or automated method such as Group Policy or systems management tools. The user must run the installation command or script as an administrator on the endpoint.

The other permission levels are not sufficient or relevant for installing a sensor on a Windows endpoint. Everyone is a group that includes all users and groups on the endpoint, but it does not grant administrator privileges. Root is a user that has full access and control over a Linux or Unix system, but it is not applicable to a Windows endpoint. User is a general term that refers to any person who uses a computer or network service, but it does not imply administrator privileges. References:

• VMware Carbon Black Cloud Sensor Installation Guide, page 7, Sensor Components section, Sensor Service (RepMqr) subsection.
• Installing Windows Sensors on Endpoints - VMware Docs, Procedure section, step 1.

Placing the device in quarantine is the recommended immediate action to prevent further exfiltration of data by the malware. Quarantine is a feature of VMware Carbon Black Cloud Endpoint Standard that allows you to isolate a device from the network, preventing any communication with other devices or external servers. This can help contain an active threat and prevent further damage. You can quarantine a device from the Devices page or from the Device Summary page. You can also unquarantine a device when the threat is resolved. References:

• VMware Carbon Black Cloud Endpoint Standard - On Demand, Module 5: Responding to Threats, Lesson 2: Quarantine a Device, slide 5.
• VMware Carbon Black Cloud Endpoint Standard, page 11, Quarantine a Device.

To create a reputation override for a company-critical application based on the highest available priority in the reputation list, the administrator must use the IT Tool method of reputation override. The IT Tool method allows the administrator to specify a path to a known IT tool application, such as C:\Program Files\IT\Tools\application.exe, and assign it the Local Approved reputation. This reputation is the highest priority in the reputation list and overrides any other reputations assigned by VMware Carbon Black or other sources. The IT Tool method is useful for applications that are already known by VMware Carbon Black, but need to be allowed to run without interference from the sensor. The other options are incorrect because they are not the highest priority in the reputation list. Option A is incorrect because the Signing Certificate method assigns the Company Approved reputation, which is lower than the Local Approved reputation. Option B is incorrect because the Hash method assigns the Company Approved or Company Banned reputation, depending on the action selected, which are lower than the Local Approved reputation. Option C is incorrect because the Local Approved method is not a valid method of reputation override. It is a reputation level that can be assigned by the IT Tool method or by the sensor for pre-existing files or files signed by a trusted certificate. References: Manage Reputations, Reputation Assignment

The path that meets the criteria for allowing application.exe using wildcards is :\Users*\Temp\Allowed\application.exe. This path specifies that the executable file can run only from inside of the user’s Temp\Allowed directory, regardless of the drive letter or the user name. The wildcards used in this path are:

• *: Matches any single character or no character at all. For example, *:\ matches any drive letter, such as C:, D:, or E:.
• **: Matches a partial path across all subdirectory levels and is recursive. For example, \Users**\ matches any subdirectory under the Users directory, such as \Users\Lorie, \Users\John, or \Users\Alice\Documents.

The other paths do not meet the criteria for allowing application.exe using wildcards. A. C:\Users?\Temp\Allowed\application.exe does not allow running from any drive other than C:, and it only matches a single character for the user name, which may not be sufficient. B. C:\Users*\Temp\Allowed\application.exe does not allow running from any drive other than C:, and it may match more than one character for the user name, which may not be desired. D. *:\Users*\Temp\Allowed\application.exe allows running from any drive, but it may match more than one character for the user name, which may not be desired. References:

• Carbon Black Cloud: How to Use Wildcards in Policy Rules - Carbon Black Community, Wildcard Description table.

This rule will prevent any application that is not listed in the Carbon Black Cloud Endpoint Standard from scraping the memory of another process, which is a common technique used by malware to retrieve credentials from the Local Security Authority Subsystem Service (LSASS). This rule will terminate the process that attempts to perform this operation, thus blocking the credential theft. This rule is more specific and effective than option A, which only applies to unknown applications, or option B, which applies to all executable files regardless of their reputation. Option C is incorrect because it will only deny the operation but not terminate the process, which may allow the malware to continue running and try other methods of credential theft. References: VMware Carbon Black Cloud Endpoint Standard Skills Reference Materials, Module 4: Endpoint Standard Rules, Lesson 2: Rule Types and Actions, slide 12.

The action that an administrator should take to ensure application.exe cannot run is to remove the Permissions rule for C:\Program Files\IT\Tools*. This is because the Permissions rule has a higher priority than the Blocking and Isolation rule, and it allows any operation on any file in that path, including application.exe. By removing the Permissions rule, the Blocking and Isolation rule will apply and terminate application.exe based on its SUSPECT_MALWARE reputation. The other options are incorrect because they will not prevent application.exe from running. Option A is incorrect because changing the reputation to KNOWN MALWARE will not override the Permissions rule that allows any operation on the file. Option B is incorrect because the file will not be blocked based on reputation alone, as the Permissions rule will bypass the reputation check. Option D is incorrect because adding the hash to the company banned list will not override the Permissions rule that allows any operation on the file. References: Precedence of Policy Rules, Set Permission Policy Rules, Set Blocking and Isolation Policy Rules

 To enable Live Response on all endpoints in a specific policy, the security administrator needs to follow the correct path to configure the required sensor policy setting. The correct path is Enforce > Policies > Policy > Sensor. This path allows the administrator to select a policy group, then click on the Sensor tab, where they can select or deselect the Enable Live Response checkbox as applicable, and then click Save. This will enable or disable Live Response for all endpoints that are assigned to that policy group. The other options are incorrect because they do not match the correctpath to configure the sensor policy setting for Live Response. References: Use Live Response, Use Live Response for VM Workloads

According to the VMware Carbon Black Cloud Endpoint Standard Skills Reference Materials, alerts are categorized as either “Threat” or “Observed” based on the severity and confidence of the event. “Threat” alerts indicate a high-severity and high-confidence event that is more likely to be malicious, such as a ransomware attack, a credential theft, or a network beacon. “Observed” alerts indicate a low-severity and low-confidence event that is less likely to be malicious, such as a suspicious registry modification, a fileless script execution, or a process injection. The categorization of alerts helps analysts prioritize their investigations and responses. References: VMware Carbon Black Cloud Endpoint Standard Skills Reference Materials, page 14, section 2.3.1.
