NEW QUESTION # 38
URL Filtering is an essential part of Web Security in the Gateway. For the Security Gateway to perform a URL lookup when a client makes a URL request, where is the sync-request forwarded from if a sync-request is required?
Answer: A
Explanation:
When a Security Gateway performs a URL lookup and the URL is not found in the local caches, a request for online categorization is necessary. This process involves the Resource Advisor Daemon (RAD), which has components in both kernel space and user space.
Based on descriptions of the URL Filtering categorization process (often cited in CCTE R81.20 materials):
A client (internal component, potentially the URLF Kernel Client or a similar kernel module handling the traffic) initiates a URL lookup.
The URL is first checked against kernel caches.
If the URL is not found in the kernel cache (a cache miss), the RAD kernel component is notified.
The client component then typically sends an asynchronous request to the RAD kernel component.
The RAD Kernel Space component is then responsible for forwarding this request to the RAD User Space module.
The RAD User Space module handles the actual online categorization, often by querying the URLF Online Service (Check Point's cloud-based categorization service).
The result is then returned, and the kernel cache is updated.
The question asks where the sync-request (or a request requiring immediate online lookup) is forwarded from. In this flow, the RAD Kernel Space acts as the intermediary that forwards the request from the initial kernel-level lookup mechanism to the user-space RAD process for further handling.
Supporting Information (derived from CCTE R81.20 related materials/discussions):
The typical flow for URL categorization when an online lookup is needed involves these steps:
"The kernel cache notifies the RAD kernel of hits and misses."
"The client sends an a-sync request back to RAD if the URL was not found." (This request goes to the RAD Kernel Space).
"The a-sync request is forwarded to the RAD User space via the RAD kernel for online categorization." This indicates that the RAD Kernel (RAD Kernel Space) is the component that forwards the request to the RAD User Space.
Therefore, if a sync-request (a request needing immediate online lookup) is required, it is forwarded from the RAD Kernel Space to the RAD User Space.
Reference Context (based on CCTE R81.20 materials and general Check Point URL Filtering architecture):
Discussions and explanations related to Check Point Certified Troubleshooting Expert (CCTE) R81.20 curriculum often detail this RAD architecture. For example, study materials might state: "RAD has a kernel module that looks up the kernel cache, notifies client about hits and misses and forwards a-sync requests to RAD user space module which is responsible for online categorization." The 1 "RAD kernel module" corresponds to the RAD Kernel Space, and it is this component that performs the forwarding action to the RAD User Space.(Exact page numbers like "CCTE R81.20, p338/339" have been referenced in public CCTE exam discussions pointing to this flow)
NEW QUESTION # 39
When viewing data for CPMI objects in the Postgres database, what table column should be selected to query for the object instance?
Answer: A
Explanation:
The CpmiHostCkp table in the Postgres database contains the data for CPMI objects, such as gateways, clusters, and servers. The table column that should be selected to query for the object instance is the objid column, which is the primary key of the table and uniquely identifies each object. The objid column can be used to join with other tables that reference CPMI objects, such as CpmiClusterMember, CpmiCluster, and CpmiServer. The objid column can also be used to retrieve the object name, IP address, type, and other attributes from the CpmiHostCkp table itself. References:

NEW QUESTION # 40
When a User process or program suddenly crashes, a core dump is often used to examine the problem Which command is used to enable the core-dumping via GAIA clish?
Answer: B
Explanation:
In Check Point Gaia, you can enable core dumping through the command line interface (clish) using the following command:
set core-dump enable
This command activates the core dump mechanism, allowing the system to generate core dump files when user processes crash. Remember to save the configuration after enabling core dumps with the command:
save config
Why other options are incorrect:
* B. set core-dump total: This command is used to set the total disk space limit for core dump files, not to enable core dumping itself.
* C. set user-dump enable: There is no such command in Gaia clish for enabling core dumps.
* D. set core-dump per_process: This command sets the maximum number of core dump files allowed per process, but it doesn't enable core dumping.
Check Point Troubleshooting References:
* Check Point R81.20 Security Administration Guide: This guide provides comprehensive information about Gaia clish commands, including those related to system configuration and troubleshooting.
* Check Point sk92764: This knowledge base article specifically addresses core dump management in Gaia, explaining how to enable and configure core dumps.
Enabling core dumps is a crucial step in troubleshooting process crashes as it provides valuable information for analysis and debugging.
NEW QUESTION # 41
In some scenarios it is very helpful to use advanced Linux commands for troubleshooting purposes. Which command displays information about resource utilization for running processes and shows additional information for core utilization and memory?
Answer: D
NEW QUESTION # 42
What does CMI stand for in relation to the Access Control Policy?
Answer: A
Explanation:
CMI stands for Context Management Infrastructure, which is a component of the Access Control Policy that enables the Security Gateway to inspect traffic based on the context of the connection. Context includes information such as user identity, application, location, time, and device. CMI allows the Security Gateway to apply different security rules and actions based on the context of the traffic, and to dynamically update the context as it changes. CMI consists of three main elements: Unified Policy, Identity Awareness, and Content Awareness.
