HCL-BF-PRO-10 Dumps With Exact Questions and Answers

A Top Level Relay is a relay that directly communicates with the BigFix Server and has other relays as its children. A Top Level Relay has no limit as to the number of relays they can manage, but it is recommended to have no more than 1000 relays per Top Level Relay for optimal performance. When designing a relay hierarchy, the BigFix Administrator should consider the following factors:

• The network bandwidth and latency between the relays and the server
• The number and size of the fixlets, actions, and reports that are exchanged between the relays and the server
• The CPU and memory resources of the relays and the server
• The relay affiliation and selection settings of the clients and the relays
• The encryption and decryption of the client reports by the relays and the server

• The BES Client Usage Profiler is a tool that collects information about the client evaluation cycle, such as the average, maximum, and minimum duration, and the percentage of time spent on different tasks, such as action, api, archive, gather, etc.1
• To enable the BES Client Usage Profiler, you need to run the task 361 TROUBLESHOOTING: Enable BES Client Usage Profiler on the target clients. This task will set the _BESClient_UsageProfiler_Enable client setting to 1 and restart the client service.2
• After the task is completed, you can use the analysis 362 TROUBLESHOOTING: BES Client Usage Profiler to view the results of the profiler. This analysis will show you the evaluation cycle statistics and the breakdown of the time spent on each task.3
• You can use this information to identify any potential issues or bottlenecks in the client evaluation cycle, such as long action duration, high api percent, or excessive gather time. You can also compare the results with other clients or the average values to see if there are any anomalies or outliers.4
• To disable the BES Client Usage Profiler, you need to run the task 363 TROUBLESHOOTING: Disable BES Client Usage Profiler on the target clients. This task will set the _BESClient_UsageProfiler_Enable client setting to 0 and restart the client service.

• 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:
