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:

To troubleshoot Identity Awareness issues related to user identification and Access Role application, you need to enable debugging for both Identity Collectors (IDC) and Identity Providers (IDP). The command pdp debug set IDC all IDP all on the gateway achieves this.
Here's why this is the correct answer and why the others are not:
* A. on the gateway: pdp debug set IDC all IDP all: This correctly enables debugging for all Identity Collectors and Identity Providers, allowing you to see detailed logs and messages related to user identification and Access Role assignment. This helps pinpoint issues with user mapping, authentication, or authorization.
* B. on the gateway: pdp debug set AD all and IDC all: This command only enables debugging for Active Directory (AD) as an Identity Provider and all Identity Collectors. It might miss issues related to other Identity Providers if they are in use.
* C. on the management: pdp debug on IDC all: This command has two issues. First, it should be executed on the gateway, not the management server, as the gateway is responsible for user identification and policy enforcement. Second, it only enables debugging for Identity Collectors, not Identity Providers.
* D. on the management: pdp debug set all: While this command might seem to enable debugging for everything, it's not specific enough for Identity Awareness troubleshooting. It might generate excessive logs unrelated to the issue and make it harder to find the relevant information.

URL Filtering is an essential part of Web Security in the Gateway that allows the administrator to control the access to web sites based on the site categorization and reputation. For the Security Gateway to perform a URL lookup when a client makes a URL request, the following steps are involved12:
* The URLF Kernel Client is the component that intercepts the URL request from the client and extracts the URL information, such as the host name, the path, and the query parameters. The URLF Kernel Client then checks the local cache to see if the URL has been previously categorized. If the URL is found in the cache, the URLF Kernel Client returns the cached category to the Security Policy and enforces the relevant action. If the URL is not found in the cache, the URLF Kernel Client sends a sync- request to the URLF User Space.
* The URLF User Space is the component that handles the sync-request from the URLF Kernel Client and performs the URL lookup. The URLF User Space first checks the local database to see if the URL has been previously categorized. If the URL is found in the database, the URLF User Space returns the database category to the URLF Kernel Client. If the URL is not found in the database, the URLF User Space sends an async-request to the URLF Online Service.
* The URLF Online Service is the component that handles the async-request from the URLF User Space and performs the URL lookup. The URLF Online Service is a cloud-based service that provides the most updated and accurate URL categorization and reputation. The URLF Online Service queries the Check Point cloud servers to get the category and reputation of the URL, and returns the result to the URLF User Space. The URLF Online Service also updates the local database and cache with the new URL information.
Therefore, the sync-request is forwarded from the URLF Kernel Client to the URLF User Space, if a sync- request is required.
