What is the best way to see how much traffic went through the firewall that was TCP, UDP and ICMP?
Which command displays FireWall internal statistics about memory and traffic?

Which command can be used to see all active modules on the Security Gateway:
In some situations, switches may not play nicely with a Check Point Cluster and it is necessary to change from multicast to broadcast. What command should you invoke to correct the issue?
What is the corresponding connection template entered into the SecureXL connection table from the connection: “10.0.0.100:1024 > 216.239.59.59:80”
The command fwaccel stat displays what information?

What could be a possible cause of the high CPU usage?
How do you enable IPv6 support on a R77 gateway running the GAiIA OS?
What command allows you to monitor IPV6 packets in the kernel module?
True or False: It is possible to operate a Security Gateway entirely with IPv6 addressing.
Does R77 SmartDashboard support IPv6?
One of IPS Layers’ main functions are to ensure compliance to well-defined protocol standards, detect anomalies if any exist, and assemble the data for further inspection by other components of the IPS engine. Which component is responsible for these functions?

Since R76 GAiA, what is the method for configuring proxy ARP entries for manual NAT rules?
The fw tab –t ___________ command displays the NAT table.
Which flag in the fw monitor command is used to print the position of the kernel chain?
A firewall has 8 CPU cores and the correct license. CoreXL is enabled. How could you set kernel instance #3 to run on processing core #5?
CoreXL on IPSO R77.20 does NOT support which of the following features?
Your customer has a well optimized Rule Base with most traffic accelerated by SecureXL. They are still seeing slow performance. They are using an 8 core machine. They see the following output from fw ctl affinity -l. What could be done to improve performance with this deployment?
What is the method to change the number of cores that CoreXL will use?
From a Best Practices perspective, what percentage of your packets should be accelerated?
Under which scenario would you most likely consider the use of Multi-Queue?
