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:

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:

The impact of using the wildcards in the path is that all executable files in the “Program Files” folder and subfolders will be ignored, including malware files. This is because the double asterisk ** matches any files or directories in that path, and the Bypass action means that the sensor will notmonitor or block any operations performed by those files. This is a very permissive and risky rule, as it could allow malicious files to run without interference from the sensor. A more restrictive and secure rule would be to specify the exact path of the application that needs to be allowed, and use the Allow and Log action instead of Bypass. This way, the sensor will only ignore the specified application, and still log its operations for visibility and analysis. References: Carbon Black Cloud: How to Use Wildcards in Policy Rules, Set Permission Policy Rules
