The HCL BigFix platform utilizes a granular Role-Based Access Control (RBAC) model for managing operator privileges. The ability to create, edit, or delete an analysis is not granted to all operators by default. This specific capability is controlled by the "Can Manage Analyses" permission. While Master Operators possess this permission inherently, it can also be assigned to Non-Master Operators through custom roles. Therefore, the defining requirement is having the specific permission, not the operator's master or non-master status.

A. Not all console operators have this permission. It must be explicitly granted through a role, unless the operator is a Master Operator.

B. Non-Master Operators can also be granted the "Can Manage Analyses" permission, so this capability is not exclusive to Master Operators.

C. Master Operators have all permissions by default, including the ability to manage analyses, making this statement incorrect.

1. HCL BigFix Platform 10.0 Documentation

"Managing operators and roles" > "Console Permissions": This section details the specific permissions available to console operators. It lists "Can Manage Analyses" and describes its function: "Allows the operator to create

edit

and delete analyses." This directly confirms that a specific permission is required.

2. HCL BigFix Platform 10.0 Documentation

"Managing operators and roles" > "Operator": This section describes the two types of operators: Master and Non-Master. It clarifies that Master Operators have all permissions

while Non-Master Operators' permissions are determined by their assigned roles

reinforcing that the permission itself is the key factor.

When configuring a scheduled activity within HCL BigFix Web Reports, the "Activity Actions" section provides three distinct options for handling the generated report. Users can choose to:

1. Email: Automatically send the report to specified recipients.

2. Archive: Save a copy of the report to a designated archive folder on the Web Reports server.

3. Customized Executable: Trigger a custom script or executable file, allowing for advanced integration and automated workflows based on the report's generation.

B. Email, Archive, and API: While BigFix has robust API capabilities, "API" is not a direct, selectable option within the Web Reports scheduled activity actions interface.

C. Email, SNMP, and Customized Executable: SNMP (Simple Network Management Protocol) is not an available action for scheduled activities in Web Reports; it is not used for report distribution in this context.

D. Email SNMP and iSiFTP: Neither SNMP nor iSiFTP are standard, built-in action options for scheduled activities in the HCL BigFix Web Reports interface.

HCLSoftware. (2023). HCL BigFix Web Reports Guide Version 10.0. In the section "Scheduling Activities

" under the sub-section "Creating a Scheduled Activity

" the guide explicitly states: "In the Activity Actions box

you can choose to have the activity send an email

save to an archive

or run a custom executable." (Reference link: HCL BigFix Web Reports Guide - Creating a Scheduled Activity)

Enabling Message Level Encryption (MLE) means every report from all 50,000 endpoints is encrypted and can only be decrypted by the BigFix Root server. This decryption process is computationally intensive and directly impacts the server's CPU. For a large-scale deployment, the cumulative effect of decrypting tens of thousands of reports significantly increases the CPU load. Therefore, ensuring the Root server has adequate CPU resources is the most critical consideration to support this configuration and maintain performance.

A. All Relays must have at least 8GB RAM to support this configuration.

Relays do not decrypt MLE-protected reports; they simply pass the encrypted data to the server. The performance impact on Relays is negligible, and there is no specific RAM requirement for them related to MLE.

C. An additional NIC must be added to the BigFix Root server to balance the extra load caused by the encrypted reports.

MLE adds minimal data overhead to reports. The primary bottleneck created by MLE is CPU processing for decryption, not network bandwidth. A standard NIC is sufficient to handle the network traffic.

D. The BESServerMaxReportDecryptions setting should be set to an appropriate value on the BigFix Root server to minimize the impact from handling the encrypted reports.

This setting tunes the number of concurrent decryption threads. While important for managing CPU usage, it is a configuration setting, not a resource requirement. The fundamental consideration is having sufficient CPU hardware (Option B) to handle the load in the first place.

Section: "Message Level Encryption (MLE)"

Page 21.

"Enabling MLE increases the CPU usage on the BigFix server because it must decrypt every report that it receives from the BigFix clients. The performance impact of MLE on the BigFix server is directly proportional to the number of reports that the server processes." (Supports B)

"The performance impact of MLE on the BigFix relays is negligible because the relays do not decrypt the reports." (Refutes A)

2. HCL BigFix Platform 10.0 Installation Guide

Chapter 2: "Installation Scenarios and Requirements"

Section: "Server Requirements".

Under the hardware requirements tables

a note states: "If you plan to enable Message Level Encryption (MLE)

the CPU requirements for the BigFix server will be higher. The additional CPU load is proportional to the number of managed endpoints." (Supports B)

3. HCL BigFix Platform 10.0 Administrator's Guide

Chapter 2: "BigFix Administration"

Section: "Securing your environment".

"Be aware that enabling this feature will increase the CPU load on your main BigFix server." (Supports B)

The guide also describes the BESServerMaxReportDecryptions setting as a way to "throttle the decryption process to reduce the CPU usage

" confirming its role as a tuning parameter rather than a primary resource requirement. (Explains why D is secondary to B)

To improve WebUI response time, an administrator can adjust the frequency at which the WebUI queries the database for new information. The WebUIAppEnvDATAREFRESHSECONDS setting controls the overall interval for refreshing WebUI data. The WebUIAppEnvCACHETTL (Time To Live) setting specifically defines how long data remains valid in the cache before it is considered stale and needs to be refreshed. Increasing the values for these settings reduces the load on the database and server, which can improve the perceived performance and responsiveness of the WebUI at the cost of data freshness.

A. WebUIAppEnvSPQUEUECONCURRENT: This setting manages the number of concurrent stored procedure calls to the database, affecting throughput, not the cache refresh interval.

C. WebUIAppEnvCACHEINTERVAL: This is not a valid or recognized advanced setting for the HCL BigFix WebUI.

D. WebUIAppEnvSITECACHESIZE: This setting controls the maximum number of sites to be held in the cache, which relates to the size of the cache, not its refresh timing.

1. HCLSoftware. (2023). HCL BigFix Platform 10.0 Documentation: List of advanced options for WebUI. In Installing > WebUI. Retrieved from HCLSoftware Help Center.

Section: List of advanced options for WebUI

Details: This document explicitly lists and describes WebUIAppEnvDATAREFRESHSECONDS as "The interval

in seconds

at which the WebUI data is refreshed" and WebUIAppEnvCACHETTL as "The time to live

in seconds

for the WebUI cache." It also defines WebUIAppEnvSPQUEUECONCURRENT and WebUIAppEnvSITECACHESIZE

confirming their purposes are unrelated to cache refresh intervals. The setting WebUIAppEnvCACHEINTERVAL is not present

confirming it is not a valid option.

The HCL BigFix architecture uses a lightweight notification mechanism to inform clients when new content (such as Fixlets, tasks, or actions) is available. The BigFix Server or Relay sends a small User Datagram Protocol (UDP) packet to the client on its listening port, which is port 52311 by default. This UDP "ping" serves as a notification, prompting the client to wake up and initiate a "gather" process to retrieve the new policy or content information from its parent relay or server. This method is highly efficient for near real-time client management across large networks.

A. TCP: TCP is used for reliable, connection-oriented communication, such as when the client uploads reports or downloads the actual action/Fixlet content, but not for the initial notification ping.

C. ICMP: ICMP is a network layer protocol used for diagnostic purposes and error reporting (e.g., the ping command), not for application-level content notifications.

D. ISMTP: This is a protocol related to email transport and is not used within the HCL BigFix communication architecture.

The Site Administrator's public/private key pair is created during the initial HCL BigFix server installation process. The installation wizard prompts the user to create a password for this key. This password protects the private key file (e.g., username.pvk), which is required for the Site Administrator to log in to the console and digitally sign actions and content. This local generation ensures that the private key remains secure and is never transmitted outside the customer's environment.

B. The BigFix License Portal is used to generate the license authorization file (license.crt) and the masthead (actionsite.afxm), not the user-specific private keys for administration.

C. For security reasons, HCL Support never generates or has access to a customer's private keys. These keys are fundamental to the security of the deployment and must be created by the customer.

D. While openssl is a cryptographic tool, the BigFix installer has its own integrated mechanism for generating the required keys. Using a separate command-line tool is not part of the standard installation procedure.

1. HCL BigFix Platform Installation Guide

Version 10.0

"Installing the server on Windows": In the section detailing the installation steps

it states: "In the IEM Site Administrator Private Key Password dialog

enter a password to protect your private key file... The installation program uses this password to create a private key file (username.pvk) that is associated with the user name that you specified." (This describes the key generation as an integral part of the installation wizard).

2. HCL BigFix Platform Installation Guide

Version 10.0

"Installing the server on Linux": The guide describes the ./install.sh script process

which includes the step: "You are prompted to create a site admin key and to provide a password for it. This key is used to authorize all the actions that you will deploy in the future." (This confirms the same key generation process occurs during the Linux installation).

3. HCL BigFix Platform Installation Guide

Version 10.0

"BigFix security": This section explains the Public Key Infrastructure (PKI) used by BigFix

clarifying that the "site-level key file" is created during installation to sign all content published on the site.

The recommended and most efficient method for updating the BigFix installation packages (Console, Agent, Relay) on the root server is by using the dedicated Fixlet provided in the "BES Support" site. When a new platform version is released, HCL publishes a Fixlet, such as "Updated Windows Installation Folders - BigFix version 10.0.8 Now Available!", which automates the process. Taking action on this Fixlet ensures that the correct files are downloaded and placed in the appropriate wwwrootbes\Installers directory, making them available for future component deployments and upgrades. This leverages the native automation capabilities of BigFix for self-management.

A. Manually downloading and replacing files is not the best practice. It is prone to human error, such as placing files in the wrong location or downloading incorrect versions, and bypasses the integrated, audited BigFix process.

B. The installer packages are not updated automatically. An administrator must explicitly initiate the update process by taking action on the relevant Fixlet to ensure the server is ready to deploy the new version's components.

C. The BigFix Administration Tool is primarily used for initial installation, license authorization, and database configuration. It is not used for operational tasks like updating the installation folders for a platform version upgrade.

1. HCL BigFix Platform 10.0 Installation Guide

"Upgrading on Windows systems

" Section: "Step 4: Update the installation folders." This section explicitly states: "To update the installation folders

run the task with the title Updated Windows Installation Folders - BigFix version Now Available! from the BES Support site." This confirms that using the specified Fixlet is the correct procedure.

2. HCL BigFix Platform 10.0 Installation Guide

"BigFix Installation Generator." This section describes how the installation folders are created initially. The upgrade process leverages a Fixlet to update the content created by this tool

rather than re-running the tool or using the Administration Tool.

When creating a new property within an Analysis in the HCL BigFix Console, the "Edit Property" dialog box is presented. This dialog contains three primary fields: "Name," "Relevance," and "Evaluate Every." The "Evaluate Every" field is a dropdown menu that allows the operator to specify the reporting interval for the property (e.g., every report, once a day). This setting controls how frequently the BigFix client evaluates the property's relevance expression and sends the result to the server, which is critical for managing endpoint performance and ensuring data timeliness.

A. Create in site: The site is the location where the Analysis (and its properties) is created, but it is not a configurable field within the individual property's creation dialog.

B. Applicability: Applicability is a relevance clause that defines which endpoints will run the entire Analysis, not a field for an individual property within that Analysis.

D. CVEID: A Common Vulnerabilities and Exposures ID (CVEID) is a metadata field used to identify security vulnerabilities, typically associated with Fixlet content, not custom properties.

The HCL BigFix platform enforces a hierarchical version compatibility rule to ensure proper communication and functionality during and after an upgrade. The server component must always be at a version greater than or equal to the relays it manages. Similarly, relays must be at a version greater than or equal to the clients that report to them. This rule facilitates a phased upgrade process, which mandates upgrading the server first, followed by the relays, and then the clients, ensuring that higher-level components can always process information from lower-level components.

A. This is an ideal end-state but not a mandatory rule during the upgrade process; mixed-version environments are fully supported.

B. This option incorrectly omits the relay component, which is critical to the BigFix hierarchy and version dependency chain.

C. This is incorrect because a relay cannot be at a lower version than a client it manages, as it might not understand the newer client's data format.

1. HCL BigFix Platform Installation Guide Version 10.0. In the "Upgrading" chapter

the section "Upgrading the BigFix components" specifies the mandatory upgrade order: "1. Server

2. Consoles

3. Relays

4. Clients". This prescribed order directly enforces the version relationship where server version >= relay version >= client version at all times during the upgrade cycle.

2. HCL BigFix Capacity Planning

Performance

and Management Guide Version 10.0. The "Upgrading" section reinforces this principle by stating

"The recommended upgrade path is to upgrade the BigFix server first

then the BigFix relays

and finally the BigFix clients." This best practice is based on the underlying technical requirement for hierarchical version compatibility.

The BigFix Client, also known as the agent, is the component installed on every managed endpoint. Its primary responsibility is to continuously run an assessment cycle. During this cycle, it evaluates the Relevance language expressions contained within all subscribed content (such as Fixlets, Tasks, and Baselines) against the current state of the local computer. This constant, intelligent evaluation allows the client to determine applicability for patches, policies, or configurations in real-time and report its status back to the BigFix Server without needing constant server polling.

B. BigFix Root Server: The server acts as the central coordinator and database for the deployment. It gathers and processes reports from clients but does not perform the state assessment on the endpoints.

C. BigFix Relay: A relay is a hierarchical distribution and collection point. It caches content from the server to serve to clients and aggregates client reports, but it does not evaluate content relevance.

D. BigFix Console: The console is the user interface for administrators. It is used to create and deploy content and view the results of the assessments performed by the clients, not to perform the assessments itself.

1. HCLSoftware BigFix Platform 10.0 Documentation

"BigFix Overview": This section describes the core components. It states

"The BigFix client

which resides on every computer that you want to manage... continuously assesses the state of the endpoint against the applied policies

and it can report the results back to the server." This directly confirms the client's role in continuous assessment.

2. HCLSoftware BigFix Platform 10.0 Documentation

"Key Concepts > Relevance": This document explains the evaluation mechanism. It details that "The BigFix client evaluates Relevance expressions on the endpoint to determine whether the endpoint is relevant for a particular action." This specifies that the evaluation logic is executed by the client on the local machine.
