Checkpoint 156-315.81 Exam With Confidence Using Practice Dumps

Each instance of VRRP running on a supported interface may monitor the link state of other interfaces. The monitored interfaces do not have to be running VRRP.

If a monitored interface loses its link state, then VRRP will decrement its priority over a VRID by the specified delta value and then will send out a new VRRP HELLO packet. If the new effective priority is less than the priority a backup platform has, then the backup platform will begin to send out its own HELLO packet.

Once the master sees this packet with a priority greater than its own, then it releases the VIP.

 A best practice before starting to troubleshoot using the fw monitor tool is to disable SecureXL. SecureXL is a performance acceleration solution that optimizes the packet flow through the Security Gateway. However, SecureXL can also bypass some inspection points and cause some packets to be invisible to fw monitor. Therefore, disabling SecureXL can ensure that fw monitor captures all the relevant packets for troubleshooting purposes. References: Check Point Security Expert R81 Course, fw monitor, SecureXL

 When SecureXL is enabled, all packets should be accelerated, except packets that match the following conditions: CIFS packets. SecureXL is a technology that accelerates network traffic processing by offloading intensive operations from the Firewall kernel to a dedicated SecureXL device. However, some packets cannot be accelerated by SecureXL due to various reasons, such as unsupported features, security policy settings, or protocol limitations. One example of packets that cannot be accelerated by SecureXL are CIFS packets, which are used for file sharing and access over SMB protocol. CIFS packets are not accelerated by SecureXL because they require stateful inspection by the Firewall kernel.
