The cloud-based SandBlast Mobile application that is used to register new devices and users is Check Point Gateway. Check Point Gateway is a web portal that allows administrators to enroll devices and users into the SandBlast Mobile service, which is a cloud-based solution that protects mobile devices from advanced threats. Check Point Gateway also allows administrators to configure policies, monitor device status, and generate reports for SandBlast Mobile. 

 The number of cores that can be used in a Cluster for Firewall-kernel on the new device with 4 cores is 4. Cluster is a feature that allows two or more Security Gateways to provide high availability and load balancing for network traffic. Firewall-kernel is a component of the Security Gateway that performs packet inspection according to security policies. The number of cores that can be used for Firewall-kernel in a Cluster depends on the number of cores available on each device in the Cluster. The Cluster will use the lowest common denominator of cores among all devices in the Cluster for Firewall-kernel. Therefore, if one device has 2 cores and another device has 4 cores, the Cluster will use 2 cores for Firewall-kernel on each device. However, if both devices have 4 cores, the Cluster will use 4 cores for Firewall-kernel on each device.

 The order of NAT priorities is determined by the type of NAT rule that is applied to the traffic. There are three types of NAT rules in Check Point: static NAT, IP pool NAT, and hide NAT12.

• Static NAT: This type of NAT rule maps a single IP address to another single IP address. It is usually used to allow external hosts to access internal servers or devices. Static NAT has the highest priority among the NAT rules, and it is applied before the security policy is enforced12.
• IP pool NAT: This type of NAT rule maps a range of IP addresses to another range of IP addresses. It is usually used to balance the load among multiple servers or devices. IP pool NAT has the second highest priority among the NAT rules, and it is applied after the security policy is enforced12.
• Hide NAT: This type of NAT rule hides a group of IP addresses behind a single IP address or an interface. It is usually used to allow internal hosts to access external resources. Hide NAT has the lowest priority among the NAT rules, and it is applied after the security policy is enforced12.

Therefore, the order of NAT priorities is: static NAT, IP pool NAT, hide NAT.

The Access Control policy supports two policy layers. These are the Network layer and the Application & URL Filtering layer. The Network layer contains rules that control the network traffic based on the source, destination, service, and action. The Application & URL Filtering layer contains rules that control the application and web access based on the application, site category, and user identity12.

The Access Control policy can also use inline layers, which are sub-policies that are embedded within a rule. Inline layers allow more granular control over specific traffic or scenarios, such as VPN, Mobile Access, or different user groups13. However, inline layers are not considered as separate policy layers, but rather as extensions of the parent rule4.

Therefore, the correct answer is A. The Access Control policy supports two policy layers.
