Free Practice Questions for Checkpoint 156-836 Exam

The Correction Layer is a Maestro component that ensures that packets from the same connection are handled by the same Security Group Module (SGM) in a multi-appliance system. This is especially important when NAT is involved, as packets sent from the client to the server can be distributed to a different SGM than packets from the same session sent from the server to the client. The Correction Layer must then forward the packet to the correct SGM.

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 correct interfaces to connect to Orchestrator 1 for downlinks’ intra-orchestrator redundancy when using two Orchestrators are Port 1 in Slot 1 and Port 1 in Slot 2. This is because each slot represents a different NIC, and each port represents a different physical link. By connecting two ports from different slots, the appliance can have redundant connections to the same orchestrator, and avoid a single point of failure in case of a NIC or link failure.

The Orchestrator MHO-170 supports QSFP and QSFP28 transceivers on its 32x 100 GbE ports. QSFP stands for Quad Small Form-factor Pluggable and QSFP28 is an enhanced version of QSFP that supports up to 28 Gbps per lane. These transceivers can provide high-speed and high-density connectivity for the Maestro environment.

The asg perf -v command is used to find bottlenecks in the system that are affecting performance, even functionality in some cases. The asg perf -v command displays the performance statistics of the Security Group Modules (SGMs) in the Security Group, such as throughput, packet rate, CPU utilization, memory usage, and more. The asg perf -v command also shows the distribution mode and the correction rate of each SGM, which can indicate potential issues with asymmetric routing or load balancing. The asg perf -v command can help identify which SGMs are overloaded, underutilized, or misconfigured, and provide insights for troubleshooting and optimization.

According to the Installing and Uninstalling a Hotfix on Quantum Maestro Orchestrators, page 1, when you apply a hotfix using gclish, the MHO distributes the hotfix to all SGMs in the SecurityGroup. The SGMs install the hotfix and reboot one by one, in ascending order of their SGM IDs. The SGMs wait for the previous SGM to finish rebooting before starting their own reboot. This ensures that there is no outage for the entire Security Group.
