The correct answer is B. Go to clash-Run cpconfig | Configure CoreXL to make use of the additional Cores | Exit cpconfig |. After replacing a single-core CPU with a multicore CPU, CoreXL must be manually configured via cpconfig to utilize the additional cores.

Deployment and Configuration

Question

Due to high CPU workload on the Security Gateway, the security administrator decided to purchase a new multicore CPU to replace the existing single core CPU. After installation, is the administrator required to perform any additional tasks?

Options

  • AGo to clash-Run cpstop | Run cpstart
  • BGo to clash-Run cpconfig | Configure CoreXL to make use of the additional Cores | Exit cpconfig |
  • CAdministrator does not need to perform any task. Check Point will make use of the newly installed
  • DGo to clash-Run cpconfig | Configure CoreXL to make use of the additional Cores | Exit cpconfig |

Why each option

After replacing a single-core CPU with a multicore CPU, CoreXL must be manually configured via cpconfig to utilize the additional cores.

AGo to clash-Run cpstop | Run cpstart

Running cpstop followed by cpstart simply restarts Check Point services without configuring CoreXL to recognize or allocate the additional CPU cores.

BGo to clash-Run cpconfig | Configure CoreXL to make use of the additional Cores | Exit cpconfig |Correct

Check Point's CoreXL technology must be explicitly configured to take advantage of additional CPU cores - this is done by running cpconfig from the CLI, navigating to the CoreXL section, and specifying the number of firewall worker instances to match the available cores, then restarting Check Point services to apply the change.

CAdministrator does not need to perform any task. Check Point will make use of the newly installed

Check Point does not automatically detect and allocate new CPU cores to CoreXL - manual configuration through cpconfig is required for the gateway to leverage the additional processing capacity.

DGo to clash-Run cpconfig | Configure CoreXL to make use of the additional Cores | Exit cpconfig |

This option also invokes cpconfig for CoreXL but includes an incorrect or additional final step that deviates from the correct procedure of exiting cpconfig and restarting Check Point services.
