Checkpoint 156-215.81 Exam With Confidence Using Practice Dumps

The BEST way to tune the profile in order to lower the CPU load still maintaining security at good level is to set the Performance Impact to Medium or lower. This will reduce the number of packets that are inspected by the Threat Prevention blades, while still providing a high level of protection . Setting High Confidence to Low and Low Confidence to Inactive will lower the security level, as it will allow more traffic that may be malicious. The problem is likely with the Threat Prevention Profile, as it can have a significant impact on the CPU utilization of the Security Gateway. Adding more memory to the appliance will not solve the problem, as memory is not the bottleneck in this case. Setting the Performance Impact to Very Low Confidence to Prevent will increase the CPU load, as it will inspect more packets and block more traffic that may be false positives.

 In hide NAT, the source IP address is translated. Hide NAT is also known as many-to-one NAT or PAT (Port Address Translation). It maps multiple private IP addresses to one public IP address by using different port numbers. Hide NAT allows outbound connections from the private network to the public network, but not inbound connections from the public network to the private network. In static NAT, the source or destination IP address is translated depending on the direction of the traffic. Static NAT is also known as one-to-one NAT or bi-directional NAT. It maps one private IP address to one public IP address and allows both outbound and inbound connections. In simple NAT, there is no translation of IP addresses. Simple NAT is also known as routing mode or transparent mode. It allows traffic to pass through the NAT device without any modification. There is no hide NAT for destination IP address translation5678 References: What Is Network Address Translation (NAT)?, Network address translation, Network Address Translation Definition, Network Address Translation (NAT)

The TCP/IP model is made up of four layers: Application, Transport, Internet, and Network Interface1, p. 10. The TCP/IP model is a simplified version of the OSI model, which has seven layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical.
