• To reconfigure a proxy server on a Windows BigFix Root server, the administrator needs to run the command BESAdmin.exe /setproxy from the BES Server folder with the appropriate parameters1.
• The command BESAdmin.exe /setproxy allows the administrator to edit the proxy configuration settings after installation by specifying the proxy host, port, user, password, exception list, secure tunneling, authentication methods, and downstream notification1.
• The command BESAdmin.exe /setproxy can also be used to delete the existing proxy settings by using the /delete parameter1.
• The command BESAdmin.exe /setproxy is only available on Windows systems. On Linux systems, the equivalent command is BESAdmin.sh -setproxy2. References:

• The Site Administrator key is a private key that is used to perform site-level tasks such as setting global system options, editing mastheads, and administering Distributed Server Architecture (DSA)1.
• The Site Administrator key is generated during the installation of the BigFix Server, when the site administrator is prompted to enter a password to encrypt the key2.
• The Site Administrator key is stored in a file named license.pvk in the BigFix Enterprise\BES Server folder on the BigFix Server3.
• The Site Administrator key is required to run the BESAdmin.exe tool, which is used to manage the BigFix Server configuration and settings.
• The Site Administrator key is also required to create the masthead file, which is a file that contains the digital signature and configuration information of the BigFix deployment.
• The Site Administrator key is different from the Master Operator key, which is used to access the BigFix Console and create other operators.

• Domains are a major organizing principle in the BigFix Console that allow you to access and manage related sites, such as Patch Management, AntiVirus Management, Power Management, and so on.
• Domains are not collections of Fixlet messages, but rather contain a set of related sites that have Fixlet messages, tasks, analyses, and other content. The content is created by HCL, other vendors, or yourself, depending on the site type and subscription.
• Domains do not provide a way to deploy actions across the network, but rather help you to find and select the relevant content for your actions. You can still use the Action Wizard or the Take Action button to deploy actions from any domain or site.
• Domains are located in the lower-left portion of the Console, where you can select the domain you want from the buttons at the bottom of the panel. The contents of the domain are then displayed in the upper-right panel, where you can filter and sort them by various criteria.
• Domains are not located under Tools in the Console, but rather under the Sites node in the navigation tree. You can also access the Manage Domains dialog from the Tools menu, where you can create, edit, or delete domains. References:

• An external site is a site that is created and maintained by HCL or a third-party vendor, and is subscribed by the BigFix administrator1. External sites provide content such as fixlets, tasks, analyses, and dashboards for various purposes, such as patching, compliance, inventory, and security1.
• The site properties for an external site in the Console show the following information2:
• Therefore, the correct answer is C. Description, as it is one of the information that is displayed in the site properties for an external site in the Console, along with Publisher and Current Version. The other options, A. Creator, B. Gather URL, and D. Created Date, are not correct, as they are either not shown or not relevant for the question. References:

• On a Windows Root Server, the service that is responsible for inserting client report data into the database is BES FillDB.
• BES FillDB is a process that runs on the BigFix Server system and is responsible for storing the information returned from the BigFix Agents into the BigFix database. This information can be data, such as the value of retrieved properties or the result of the evaluation of the applicability relevance or the success criteria of Fixlets and Tasks, or the information contained in a report returning the result of a BigFix Query1.
• BES FillDB reads the buffer directory content, parses the report, and stores the report data in the database. It also offers a parameter called DatabaseBoostLevel to optimize BigFix performance2.
• The other services listed are not responsible for inserting client report data into the database. BES ServerDB Plugin Service is a service that allows the BigFix Server to communicate with the database. BES Root Server is a service that manages the communication between the BigFix Server and the BigFix Agents. BES GatherDB is a service that gathers the site content from the BigFix Server and stores it in the database3. References:

• BigFix Clients use UDP (User Datagram Protocol) to automatically find their closest relay based on network hops12.
• UDP is a connectionless protocol that does not guarantee reliable delivery of packets, but is faster and more efficient than TCP (Transmission Control Protocol)3.
• BigFix Clients send UDP packets to the BigFix Server and all the BigFix Relays in their subnet, and wait for responses12.
• The BigFix Server and the BigFix Relays reply with UDP packets containing their relay information and the number of hops to reach them12.
• The BigFix Client compares the responses and selects the relay with the lowest number of hops as its closest relay12.
• If the BigFix Client does not receive any response within a timeout period, it assumes that there is no relay in its subnet and falls back to the BigFix Server12. References:

• UDP (User Datagram Protocol)

• The license.pvk file is the private key file that is part of the BigFix license. It is protected by a password that is set during the installation of the BigFix server.
• The license.pvk file is used to authenticate the BigFix Master Operators, who are the highest level of authority in the BigFix hierarchy. They can perform any action on any computer or site in the BigFix deployment.
• The license.pvk file is also used to sign the masthead file, which contains the configuration settings and the public key for the BigFix deployment. The masthead file isdistributed to all BigFix components, such as clients, relays, and consoles, to verify the identity and authority of the BigFix server.
• The license.pvk file is not used to authenticate the BigFix Site Administrator, who is a special Master Operator that can manage the license and the masthead files. The Site Administrator uses the site admin password to access the license.pvk file and perform license-related tasks.
• The license.pvk file is not used to authenticate the BigFix local operators, who are the lower level of authority in the BigFix hierarchy. They can only perform actions on the computers and sites that are assigned to them by the Master Operators. The local operators use their username and password to log in to the BigFix console.
• The license.pvk file is not used to authenticate the BigFix LDAP operators, who are the local operators that are authenticated by an external LDAP server. They use their LDAP credentials to log in to the BigFix console. References:

• If UDP is not allowed on a network segment, the BigFix clients on that segment will not receive the UDP notifications from the server or relay, and will rely on the default 45-minute polling interval to check for new actions.1
• To reduce the delay in receiving new actions, you can enable the client polling feature, which allows the clients to poll the server or relay more frequently for new commands.2
• To enable the client polling feature, you need to set two client settings on the target clients:2
• You can set these client settings either through the console or manually on the endpoint.4
• After setting these client settings, the clients will poll the server or relay at the specified interval and receive new actions faster.

• To create a Custom Site, you need to select Tools > Create Custom Site from the BigFix Console and enter a name for your site. You can also provide a description and a domain for your site.
• To assign permission levels to operators, you need to click the Operator Permissions tab from the site dialog and select the operators from the list. You can also grant read permission globally to all operators by clicking the corresponding button.
• The permission levels that can be assigned to operators are:

• When an action is performed by the Master Operator, the action is saved in the Master Action Site, which is a special site that contains all the actions taken by the Master Operator.
• The Master Action Site is replicated to all the relays and clients in the deployment, so that they can receive and execute the actions from the Master Operator.
• The Master Action Site is also visible to all the operators in the console, but only the Master Operator can create, modify, or delete actions in this site.
• The Master Action Site is different from the Master Operator Site, which is a custom site that contains content created by the Master Operator, such as Fixlets, tasks, analyses, and baselines.
• The Master Operator Site is not replicated to the relays and clients, but it can be subscribed to by other operators or computers.
• The Master Operator Site is also different from the source site of a Fixlet, which is the site where the Fixlet was originally published by the content provider, such as HCL or a third-party vendor.
• The source site of a Fixlet is not affected by the actions taken by the Master Operator, unless the Master Operator modifies the Fixlet itself and republishes it to the same site or a different site.
• The Local Operator Site is a custom site that contains content created by a non-master operator, such as Fixlets, tasks, analyses, and baselines.
• The Local Operator Site is not replicated to the relays and clients, but it can be subscribed to by other operators or computers.
• The Local Operator Site is not affected by the actions taken by the Master Operator, unless the Master Operator modifies the content in the Local Operator Site and republishes it to the same site or a different site. References:

• The WebUI is a web-based interface that provides access to the flexibility and power of BigFix.
• The WebUI has some upper use limits that depend on many factors, such as the number of endpoints, the workload, the time of day, the server location, and the number of concurrent users.
• Concurrent users are defined as highly active users who perform multiple actions per minute on the WebUI.
• According to the BigFix Capacity Planning Guide, both the Windows and Linux WebUI instances support 36 concurrent users on a 250k deployment base. This is the recommended scalability limit for the WebUI server on BigFix v10.x.
• The WebUI also requires additional hardware resources, such as CPU, memory, and storage, to power the WebUI. These resources are in addition to the BigFix root server requirements and depend on the number of concurrent users.
• The WebUI also implements a database cache for several counters to improve the WebUI response times. The cache has a default refresh interval of 10 minutes. References:
• Hardware Requirements
• WebUI Administrators Guide
• BigFix WebUI

Here is a step by step comprehensive explanation of why this is the case:

• The Action Script you are testing is trying to stop, start, and execute a service using batch commands.
• The first line of the script uses the “appendfile” command to create a new file with the content “net stop myService”.
• The second line of the script uses the “move” command to rename the file created by “appendfile” to “c:\runme.bat”.
• The third line of the script uses the “waithidden” command to execute the file “c:\runme.bat” and wait for it to finish.
• The fourth line of the script uses the “appendfile” command again to create a new file with the content “net start myService”.
• The fifth line of the script uses the “move” command again to rename the file created by “appendfile” to “c:\runme.bat”.
• The sixth line of the script uses the “waithidden” command again to execute the file “c:\runme.bat” and wait for it to finish.
• The error occurs at the fifth line of the script because “appendfile” is trying to copy content to “c:\runme.bat” which already exists due to the previous actions in the script. In BigFix Action Script, “appendfile” is used to create a new file or append to an existing one, but it seems there’s an issue with overwriting or permissions that causes this line to fail.
• To fix this error, you can either delete the file “c:\runme.bat” before using “appendfile” again, or use a different file name for the second “appendfile” command.

• The WebUI cache is used to improve the response time of the WebUI by storing and refreshing some data that requires complex calculations, such as the number of applicable devices or patches1.
• The cache refresh interval, also known as the cache Time To Live (TTL) value, determines how often the cached data is invalidated and updated1. The default value is 600 seconds (10 minutes)1.
• To change the cache refresh interval, you can use the client setting _WebUIAppEnv_CACHE_TTL and enter the desired interval in seconds1. The minimum value is 180 seconds (3 minutes)1.
• Increasing the cache refresh interval can reduce the impact on system resources, especially for large deployments and intensive patching activities1. However, it can also affect the freshness of the cached data1.
• Another setting that affects the WebUI caching is _WebUIAppEnv_CACHE_INTERVAL, which determines how often the WebUI checks for new data from the BigFix server1. The default value is 60 seconds1.
• Decreasing the cache interval can improve the responsiveness of the WebUI, but it can also increase the load on the BigFix server1. Therefore, you should balance the cache interval and the cache TTL values according to your needs and environment1.
• The other settings, _WebUIAppEnv_SP_QUEUE_CONCURRENT, _WebUIAppEnv_DATA_REFRESH_SECONDS, and _WebUIAppEnv_SITE_CACHE_SIZE, are not related to the WebUI cache refresh interval12.
• _WebUIAppEnv_SP_QUEUE_CONCURRENT limits the number of stored procedures that run simultaneously per app in the background that update cache values1. The default value is 51.
• _WebUIAppEnv_DATA_REFRESH_SECONDS determines how often the WebUI polls the BigFix server for new data2. The default value is 15 seconds2.
• _WebUIAppEnv_SITE_CACHE_SIZE specifies the maximum size of the site cache in megabytes2. The default value is 100 MB2.

According to the BigFix Platform documentation, the upgrade Fixlet in the Support site does not upgrade a remote server correctly. You must run the full BigFix server installer to perform the upgrade. Remote database setups might encounter problems during upgrade and require resetting database connection settings after manually running the BigFix Server installer1.

The upgrade procedure is as follows:

• Upgrade the Server Installers using the Support Fixlets.
• Run the Server installer as a user that has DB Owner or SA permissions to the database server. The installer recognizes that the Server is at an earlier version and asks if you want to upgrade to the latest version.
• Run the BigFix Administrator Tool (BESAdmin.exe) to update the remote database tables; you will be prompted for the site admin password. Note: The BESAdmin.exe should be run automatically, if your account has the DB Owner or SA privileges to the remote database.
• The BigFix server is now correctly upgraded.

The other options (A, B, and C) are not correct because:

• Running the server installer as a local administrator does not guarantee that the user has the appropriate database permissions.
• Using the upgrade Fixlets from the console does not work for a remote server setup.
• Upgrading the server installers and using the upgrade Fixlets from the BigFix Console is redundant and unnecessary.

• A Non-Master operator can create a Retrieved Property by creating an Analysis, which is a collection of properties and relevance expressions that can be evaluated on a set of computers1.
• To create an Analysis, the operator needs to have the Create Custom Content permission and the Read permission on the site where the Analysis will be created2.
• To create an Analysis, the operator can follow these steps3:
• After creating the Analysis, the operator can activate it by right-clicking on it and choosing Activate from the context menu. The Analysis will then be evaluated on the computers that match the relevance expression and the property values will be reported to the server4.
• The operator can view the property values by selecting the Analysis from the Analyses list area in the Console and then selecting the Results tab. The property values will be displayed in the columns corresponding to the property names.
• The operator can also use the property values as filters, sorts, or targets in other Console features, such as computer listings, Fixlet actions, or Web Reports.
