2. 1.Which of the following is a core function of Check Point VSX technology? A. Provides high availability only for physical firewalls B. Enables multiple virtual security gateways on one device C. Disables stateful inspection on all virtual systems D. Supports only Layer 2 switching Answer: B Explanation: Check Point VSX allows multiple virtual firewalls to run on a single hardware platform. This consolidates infrastructure, reduces costs, and maintains segmentation using independent security policies and routing. 2.What is the role of the VSX Gateway? A. Central management server for all firewalls B. Host for physical firewall interfaces C. Virtualized platform hosting virtual systems D. Management database repository Answer: C Explanation: The VSX Gateway hosts virtual systems such as Virtual Systems (VS), Virtual Routers, and Virtual Switches. It acts as the core virtualization engine, enabling the creation and operation of these virtual components. 3.Which of the following components are considered part of the VSX environment? (Choose two) A. Virtual Switch B. SmartEvent C. Virtual Router D. ClusterXL Answer: A, C Explanation: Virtual Switches and Virtual Routers are integral components in VSX that handle Layer 2 and Layer 3 traffic respectively. They help manage internal connectivity between Virtual Systems and external networks. 4.What is the purpose of the VS0 context in a VSX system? A. Routing traffic between VSs B. Hosting user authentication services C. Managing shared operating system components D. Providing web filtering Answer: C Explanation: VS0 is the default context used by the VSX Gateway to manage shared resources like the kernel and operating system configurations. It does not perform firewall filtering itself. 5.Which of the following are benefits of using VSX technology in enterprise networks? (Choose three) 2 / 4

3. A. Hardware resource sharing B. Simplified policy creation across gateways C. Logical separation of customer environments D. Reduced hardware sprawl Answer: A, C, D Explanation: VSX optimizes resource usage by virtualizing gateways, reduces hardware needs, and provides complete isolation between virtual environments, making it ideal for MSPs or segmented enterprise networks. 6.In VSX, what does each Virtual System (VS) typically represent? A. An entire Layer 3 network B. A single VLAN C. A virtualized security gateway D. A hardware firewall instance Answer: C Explanation: Each Virtual System in VSX acts as an independent virtualized security gateway with its own rule base, interfaces, and routing table, allowing isolated policies for different network segments or tenants. 7.Which of the following VSX components performs Layer 3 routing? A. Virtual Router B. Virtual Switch C. VS0 D. Smart Dashboard Answer: A Explanation: The Virtual Router component within VSX is responsible for interconnecting networks at Layer 3. It enables packet forwarding and dynamic routing between Virtual Systems and external networks. 8.What is the main difference between a Virtual Router and a Virtual Switch in VSX? A. Routers are physical, switches are virtual B. Virtual Routers operate at Layer 3, switches at Layer 2 C. Switches apply policies, routers do not D. Virtual Switches are managed by SmartView Monitor Answer: B Explanation: In VSX, Virtual Routers forward packets at Layer 3 based on IP routing, while Virtual Switches operate at Layer 2, handling MAC-based forwarding within the virtual environment. 9.Which two tools are used for managing VSX objects? (Choose two) A. SmartView Tracker B. SmartConsole C. VSX Provisioning Tool D. Gaia Portal 3 / 4

4. Answer: B, C Explanation: SmartConsole provides GUI-based management of VSX objects, while the VSX Provisioning Tool offers CLI-based automation for VSX object creation and configuration. These tools ensure flexibility and control. 10.What role does the Security Management Server play in a VSX setup? A. Acts as a virtual router B. Hosts firewall policies for VSs C. Stores log data only D. Forwards network traffic Answer: B Explanation: The Security Management Server centrally manages security policies for all VSs. It pushes configurations and policies to individual virtual systems running on the VSX Gateway. 11.Which of the following statements about traffic flow in a VSX environment is correct? A. All VSs share one IP stack B. Traffic between VSs always goes through external interfaces C. Virtual Switches or Routers direct internal VS-to-VS traffic D. VS0 handles inter-VS traffic routing Answer: C Explanation: Virtual Switches or Routers are responsible for directing traffic between Virtual Systems. These internal components enable isolated routing or switching without involving external interfaces. 12.How does a Virtual Switch differ from a traditional switch? A. It lacks port mirroring B. It cannot filter VLANs C. It’s configured within VSX and runs in the VSX Gateway D. It has no MAC address table Answer: C Explanation: Virtual Switches in VSX provide internal Layer 2 connectivity between VSs and are software-based constructs running within the VSX Gateway, offering the same functionalities as physical switches. 13.Which components are mandatory when creating a new Virtual System (VS)? (Choose two) A. External interface B. Dedicated routing engine C. Policy package D. Virtual Switch or Router connection Answer: C, D 4 / 4
