Threat Extraction is a software blade that delivers PDF versions of original files with active content removed. Active content, such as macros, scripts, or embedded objects, can be used by attackers to deliver malware or exploit vulnerabilities. Threat Extraction removes or sanitizes the active content from the files and converts them to PDF format, which is safer and more compatible. Threat Extraction can also work together with Threat Emulation to provide both clean and original files to the users.

 SecureXL is a technology that accelerates the performance of the Check Point Security Gateway by offloading CPU-intensive operations from the Firewall kernel to the SecureXL device. SecureXL can handle various types of traffic, such as TCP, UDP, ICMP, non-IP, VPN, NAT, etc. SecureXL can also work with various features, such as CoreXL, ClusterXL, QoS, etc.

One way to indicate that SecureXL is enabled is to use the fwaccel commands in clish. Clish is a command-line shell that provides a user-friendly interface for configuring and managing Check Point products. The fwaccel commands are used to control and monitor SecureXL operations, such as enabling or disabling SecureXL, viewing SecureXL statistics, managing SecureXL templates, etc. For example, the command fwaccel stat shows the status of SecureXL, such as whether it is on or off, how many packets are accelerated or not accelerated, etc.

The other options are not valid indicators of SecureXL being enabled:

• A. Dynamic objects are available in the Object Explorer: Dynamic objects are objects that represent IP addresses that change over time, such as VPN clients, DHCP clients, etc. Dynamic objects are available in the Object Explorer regardless of whether SecureXL is enabled or not.
• B. SecureXL can be disabled in cpconfig: Cpconfig is a command-line tool that allows you to configure various settings of Check Point products, such as administrator password, GUI clients, SNMP extension, etc. SecureXL can be disabled in cpconfig only if it was enabled before. Therefore, this option does not indicate that SecureXL is enabled.
• D. Only one packet in a stream is seen in a fw monitor packet capture: Fw monitor is a command-line tool that allows you to capture and analyze network traffic passing through the Security Gateway. Fw monitor shows the traffic at different inspection points in the Firewall kernel. If SecureXL is enabled, some packets may be accelerated by SecureXL and bypass the Firewall kernel inspection. Therefore, fw monitor may not see all packets in a stream. However, this does not mean that only one packet in a stream will be seen by fw monitor. Some packets may still go through the Firewall kernel inspection and be seen by fw monitor. Therefore, this option does not indicate that SecureXL is enabled.

Therefore, the correct answer is C.

 For ClusterXL to work properly, one of the mandatory requirements is that the Magic MAC number must be unique per cluster node. The Magic MAC number is a MAC address that is used by ClusterXL to hide the physical MAC addresses of the cluster members from the network. This way, the cluster can present a single virtual MAC address to the network, and avoid ARP issues when a failover occurs. The Magic MAC number is derived from the Cluster Virtual IP address, which must also be unique per cluster. 

To deploy a TE250X Check Point appliance just for email traffic and in-line mode without a Check Point Security Gateway, you can utilize Check Point Cloud Services. In this scenario, you can leverage cloud-based email security services provided by Check Point without the need for an on-premises Security Gateway.

Option C correctly states that you can use only Check Point Cloud Services for this scenario, making it the verified answer.
