Explanation
The type of SecureXL template that is not valid among the options is Deny template. SecureXL templates are pre-allocated data structures that store information about connections that match certain criteria. They are used to accelerate the processing of packets that belong to those connections. The valid types of SecureXL templates are Accept, Drop, NAT, and Crypt. The Accept template is used for connections that are allowed by the Firewall policy. The Drop template is used for connections that are blocked by the Firewall policy. The NAT template is used for connections that require Network Address Translation. The Crypt template is used for connections that require encryption or decryption. References: [SecureXL Templates]

Two policy layers:
- Network Policy Layer
- Application Control Policy Layer

Comprehensive and Detailed Explanation: The "MAC magic" value, also known as the "Cluster Global ID", is a mechanism that identifies different clusters on the same network segment. It is used to prevent MAC address conflicts and ensure proper load balancing among cluster members. The "MAC magic" value is a hexadecimal number that is appended to the virtual MAC address of the cluster interface. By default, the "MAC magic" value is set to 1 for all clusters, but it must be changed manually if there is more than one cluster connected to the same VLAN. Otherwise, the clusters will not be able to communicate with each other or with external hosts.
The "MAC magic" value does not need to be modified under the other conditions listed in the question. The firewall cluster can use either Broadcast or Multicast for CCP traffic without affecting the "MAC magic" value. The number of members in a firewall cluster also does not affect the "MAC magic" value, as long as they belong to the same cluster and have the same Cluster Global ID.

The Compliance Blade allows you to search for text strings in many windows and panes, to search for a value in a field, the syntax is field_name:string. For example, to search for all rules that have a comment containing
"VPN", the syntax is comment:VPN. The other options are not valid syntaxes for searching for a value in a field3. References: 3: Check Point Software, Getting Started, Searching for Text Strings.
