IBM Security Access Manager V9.0 Deployment — Question 20

A large bank has multiple applications protected by two identically configured WebSEAL servers. One junction supports a reporting application that frequently expenses performance issues which slows response time. The worst case results in the entire site becoming unresponsive when all WebSEAL worker threads on all WebSEAL instances are consumed on the junctions to this one reporting application.
Which configuration change will prevent this situation from occurring without impacting the behavior of any other application (junction), and keeping the entire site up?

Answer options

• A. Change worker-thread-hard-limit to 75 in WebSEAL configuration file on both WebSEAL servers.
• B. Use the "throttle" option on the "pdadmin server task" command for the reporting application junction on both WebSEAL instances.
• C. Use the ""L 75 and ""f options on the "pdadmin server task" command for the reporting application junction on both WebSEAL instances.
• D. Create a third WebSEAL instance supporting only this one reporting application and load balance requests across all three WebSEAL instances.

Correct answer: C

Explanation

Option C is correct because using the 'L 75' and 'f' options on the 'pdadmin server task' command allows you to specifically limit the resources allocated to the reporting application, preventing it from monopolizing all worker threads. Options A and B do not provide an effective solution to isolate the reporting application's resource usage, while option D introduces unnecessary complexity without directly addressing the issue at hand.
