Exam 156-315.81 topic 1 question 214 discussion

its definitely C cause i had an issue with a customer that got a CP with 4 cores and not 2 and he wanted them to be in a cluster... needs to the same in short...

I think it is C: All Cluster Members must run on identically configured hardware platforms.

ClusterXL operation completely relies on internal timers and calculation of internal timeouts, which are based on hardware clock ticks. Therefore, in order to avoid unexpected behavior, ClusterXL is supported only between machines with identical CPU characteristics.

Answer is C: 2 cores

A, based off this.. 4 cores, 4 instances When you enable CoreXL, the number of kernel instances is based on the total number of CPU cores. https://sc1.checkpoint.com/documents/R80.10/WebAdminGuides/EN/CP_R80.10_PerformanceTuning_AdminGuide/html_frameset.htm?topic=documents/R80.10/WebAdminGuides/EN/CP_R80.10_PerformanceTuning_AdminGuide/91164

I think A is correct https://sc1.checkpoint.com/documents/R80.10/WebAdminGuides/EN/CP_R80.10_PerformanceTuning_AdminGuide/html_frameset.htm?topic=documents/R80.10/WebAdminGuides/EN/CP_R80.10_PerformanceTuning_AdminGuide/91164

The number of cores should be equal
