 Packet filtering, stateful inspection, and application layer firewall are technologies used to deny or permit network traffic based on different criteria. Packet filtering is a basic firewall technology that examines the header of each packet and compares it to a set of rules to decide whether to allow or drop it. Stateful inspection is an advanced firewall technology that tracks the state and context of each connection and applies security rules based on the connection information. Application layer firewall is a firewall technology that inspects the content and behavior of applications and protocols at the application layer of the OSI model and enforces granular policies based on the application identity, user identity, and content type.

 Windows Management Instrumentation (WMI) is a protocol that allows remote management and monitoring of Windows systems. It is used by AD Query to connect to the Active Directory Domain Controllers and query them for user and computer information. AD Query uses WMI to get real-time updates on user logon events, group membership changes, and computer status changes. WMI is not the same as LDAP, which is a protocol for accessing and modifying directory services. HTTPS and RDP are also different protocols that are not used by AD Query.

Which command is used to obtain the configuration lock in Gaia? The command that is used to obtain the configuration lock in Gaia is lock database override. This command allows a user to take over the configuration lock from another user who is currently logged in with read/write access. The other user will be forced to logout and will lose any unsaved changes. This command should be used with caution and only when necessary. References: Gaia Administration Guide R81, page 15.

High Availability (HA) is a deployment scenario where two or more Security Management Servers are configured to work together as a cluster. One server acts as the Primary server and handles all management operations, while another server acts as the Secondary server and serves as a backup. If the Primary server fails, the Secondary server takes over and becomes active. The cluster members communicate using a Virtual IP (VIP) address, which is used by SmartConsole to connect to the active server. If the Primary server is temporarily down, the administrator does not need to do anything, as SmartConsole will automatically connect to the VIP address and reach the Secondary server that has become active. Therefore, the correct answer is A.

Check Point ClusterXL Active/Active deployment is used when there is Load Sharing solution set up. Load Sharing is a ClusterXL mode that allows distributing the network traffic between all cluster members, while still providing high availability in case of failures. Load Sharing can be configured as either Unicast or Multicast, depending on the network topology and switches support. References: R81 ClusterXL Administration Guide, page 9.

 The best sync method in the ClusterXL deployment is to use one dedicated sync interface. This means that one interface on each cluster member is used exclusively for synchronization traffic, which improves performance and security. Using multiple clusters or sync interfaces is not recommended, as it can cause network congestion or synchronization issues.

The verified answer is B. Automatic proxy ARP configuration can be enabled.

Proxy ARP is a feature that allows a gateway to respond to ARP requests on behalf of another IP address that is not on the same network segment. Proxy ARP is required for manual NAT rules when the NATed IP addresses are not routed to the gateway1.

By default, proxy ARP for manual NAT rules has to be configured manually by editing the local.arp file or using the CLISH commands on the gateway2. However, since R80.10, there is an option to enable automatic proxy ARP configuration for manual NAT rules by modifying the files $CPDIR/tmp/.CPprofile.sh and $CPDIR/tmp/.CPprofile.csh on the gateway3.

fw ctl proxy is a command that displays the proxy ARP table on the gateway, but it does not configure proxy ARP4.

Translate Destination on Client Side is a NAT option that determines whether the destination IP address is translated before or after the routing decision. It does not affect proxy ARP.
