When simulating a problem on a ClusterXL cluster with the command "cphaprob –d STOP -s problem -t 0 register" to initiate a failover on an active cluster member, you can use the command "cphaprob –d STOP unregister" to remove the problematic state and return the cluster to normal operation.

Option A correctly identifies the command that allows you to remove the problematic state, making it the verified answer.

Check Point API is a set of web services that enable the usage of functions and commands in a dynamic and automated fashion. Check Point API is available in different types, each serving a different purpose and functionality. According to the Check Point Resource Library1, the following are the types of Check Point API available in R81.x:

• Identity Awareness Web Services: This type of API allows external applications to send identity and location information to the Security Gateway, which can then use this information for policy enforcement. Identity Awareness Web Services can be used for scenarios such as guest registration, captive portal, identity agents, etc.
• OPSEC SDK: This type of API provides a framework for developing applications that interact with Check Point products using the OPSEC (Open Platform for Security) protocol. OPSEC SDK can be used for scenarios such as log export, event management, anti-virus integration, etc.
• Management: This type of API allows external applications to perform management operations on the Check Point Management server using RESTful web services. Management API can be used for scenarios such as policy installation, object creation, configuration backup, etc.

Mobile Access is not a type of Check Point API, but rather a feature that provides secure remote access to corporate resources from various devices. Mobile Access uses SSL VPN technology and supports different authentication methods and access scenarios.

VPN Link Selection is a feature that allows the Security Gateway to select the best link for each VPN tunnel based on the network topology and the Link Selection configuration1. When the primary VPN link goes down, the Firewall can update the Link Selection entries to start using a different link for the same tunnel, as long as the remote peer supports this feature and has multiple IP addresses configured2. This way, the VPN tunnel can be maintained without interruption or renegotiation. The other options are not correct because:

Firewall

• A. The Firewall will not drop the packets, but will try to send them over another link if possible.

Firewall

• C. The Firewall will not send out the packet on all interfaces, but will use the routing table to determine the best interface for each destination.

Firewall

• D. The Firewall will not inform the client that the tunnel is down, but will try to keep the tunnel up by switching to another link.

 SecureXL templates are a mechanism to accelerate the rate of connection establishment by grouping connections that match a particular service and whose sole differentiating element is the source port. SecureXL templates enable even the very first packets of a TCP handshake to be accelerated, without waiting for the Firewall kernel to create a connection entry. The first packets of the first connection on the same service will be forwarded to the Firewall kernel, which will then create a template of the connection. The template will contain all the relevant information for the connection, such as source and destination IP addresses, destination port, NAT information, policy decision, etc. The template will be used by SecureXL to handle subsequent connections on the same service, without involving the Firewall kernel. This reduces the CPU load and increases the throughput.

There are three types of SecureXL templates: Accept, Drop, and NAT. Accept templates are used for connections that are allowed by the Firewall policy. Drop templates are used for connections that are blocked by the Firewall policy. NAT templates are used for connections that require NAT translation. Deny templates are not a valid type of SecureXL template.
