Checkpoint 156-836 - Check Point Certified Maestro Expert (CCME) R81.X

This is the correct answer because Layer 4 distribution is not recommended when dynamic routing protocols are used in Maestro. Layer 4 distribution is a feature that adds the source and/or destination ports to the distribution equation, which can improve the load balancing among the SGMs. However, it can also cause issues with the correction layer, which is a mechanism that ensures the packets are processed by the correct SGM. Dynamic routing protocols, such as BGP or OSPF, use specific ports to exchange routing information and establish neighbor relationships. If Layer 4 distribution is enabled, it can interfere with the routing protocol packets and cause routing instability or failures.

The "asg monitor" command generally would show real-time cluster status of appliances in a security group, focusing on health and operational status.

The asg stat -v command is used to verify the status of Security Group Members (SGMs) during an upgrade in a Maestro environment. This command provides detailed status information, including whether SGMs are in the UP state, which is critical before proceeding with upgrades to other SGMs to ensure system stability and continuity.

Exact Extract:

“The command ‘asg stat -v’ can be used during an upgrade to verify that the upgraded Security Group Members (SGMs) have returned to UP status before upgrading other SGMs. This command provides a detailed view of the status of all SGMs in the Security Group, ensuring that the upgraded members are operational.”

Explanation of Options:

A. asg monitor: Incorrect, as asg monitor is used for real-time monitoring but does not provide detailed status verification for SGMs during upgrades.

B. cpview: Incorrect, as cpview provides performance and system statistics but is not specific to verifying SGM status post-upgrade.

C. asg perf -v: Incorrect, as asg perf -v focuses on performance metrics, not SGM status verification.

D. asg stat -v: Correct, as this command is explicitly used to check the UP status of SGMs during upgrades, as per the documentation.
