QuestionQ1

Advanced Troubleshooting Techniques

If IPS protections that stop SecureXL from accelerating traffic, such as Network Quota, Fingerprint Scrambling, and TTL Masking, must be used, what practice is recommended to improve gateway performance?

  • A Use the IPS exception mechanism
  • B Disable all such protections
  • C Disable SecureXL and use CoreXL
  • D Upgrade the hardware to include more Cores and Memory
Explanation

Certain IPS protections inspect or alter every packet in a flow and therefore force the affected connections out of the SecureXL accelerated (fast) path and into F2F processing, which can significantly reduce gateway throughput. Check Point recommends using the IPS protections' exception mechanism to limit application of protections like Network Quota, Fingerprint Scrambling, and TTL Masking to only the traffic/scope that genuinely needs them, so that unrelated connections remain eligible for SecureXL acceleration instead of unnecessarily bypassing it.

QuestionQ2

Advanced Kernel Debugging

The Check Point Firewall Kernel is the core component of the Gala operating system and an integral part of the traffic-inspection process. Two procedures are available for debugging the firewall kernel. Which procedure/command is used for detailed troubleshooting and requires more resources?

  • A fw ctl debug/kdebug
  • B fw ctl zdebug
  • C fw debug/kdebug
  • D fw debug/kdebug ctl
Explanation

fw ctl zdebug performs kernel debugging while presenting the debug output in real time. This detailed tracing raises CPU load and should be run with appropriate resource and maintenance considerations.

QuestionQ3

Advanced Kernel Debugging

What are the four methods for inserting an FW Monitor into the firewall kernel chain?

  • A Relative position using location, relative position using alias, absolute position, all positions
  • B Absolute position using location, absolute position using alias, relative position, all positions
  • C Absolute position using location, relative position using alias, general position, all positions
  • D Relative position using geolocation, relative position using inertial navigation, absolute position, all positions
Explanation

FW Monitor can be inserted by specifying a relative position number from the chain listing, a relative position alias, or an absolute chain position. The -p all option inserts it at all inbound and outbound positions. Check Point: fw monitor

QuestionQ4

Advanced Troubleshooting Techniques

The customer uses Check Point appliances that were configured long ago by third-party administrators. The current policy contains various enabled IPS protections and the Bypass Under Load function. Bypass Under Load is set to disable IPS inspections when CPU and memory usage is above 80%.

The customer reports that IPS protections do not work at all, irrespective of CPU and memory usage. What could cause this behavior?

  • A The kernel parameter ids_assume_stress is set to 0
  • B The kernel parameter ids_assume_stress is set to 1
  • C The kernel parameter ids_tolerance_no_stress is set to 10
  • D The kernel parameter ids_tolerance_stress is set to 10
Explanation

Setting ids_assume_stress to 1 makes the IPS engine assume the gateway is under load. With Bypass Under Load enabled, IPS inspection is therefore bypassed continuously instead of only after CPU or memory usage exceeds 80%.

QuestionQ5

Management Database and Processes

Which SecureXL database is the primary one for tracking the acceleration status of traffic?

  • A cphwd_db
  • B cphwd_tmp1
  • C cphwd_dev_conn_table
  • D cphwd_dev_identity_table
Explanation

SecureXL records accelerated traffic connection state in cphwd_db, its primary connections database. Check Point documentation describes this table as being maintained by SecureXL for connection tracking.
