What is mandatory for ClusterXL to work properly?
- A. The Sync interface must not have an IP address configured
- B. If you have "Non-monitored Private" interfaces, the number of those interfaces must be the same on all cluster members
- C. The number of cores must be the same on every participating cluster node
- D. The Magic MAC number must be unique per cluster node
正解：D
解説：
Explanation
For ClusterXL to work properly, one of the mandatory requirements is that the Magic MAC number must be unique per cluster node. The Magic MAC number is a MAC address that is used by ClusterXL to hide the physical MAC addresses of the cluster members from the network. This way, the cluster can present a single virtual MAC address to the network, and avoid ARP issues when a failover occurs. The Magic MAC number is derived from the Cluster Virtual IP address, which must also be unique per cluster.
質問 # 67
Which of the following statements about Site-to-Site VPN Domain-based is NOT true?
- A. Domain-based- VPN domains are pre-defined for all VPN Gateways. A VPN domain is a host or network that can send or receive VPN traffic through a VPN Gateway.
- B. Route-based- The Security Gateways will have a Virtual Tunnel Interface (VTI) for each VPN Tunnel with a peer VPN Gateway. The Routing Table can have routes to forward traffic to these VTIs. Any traffic routed through a VTI is automatically identified as VPN Traffic and is passed through the VPN Tunnel associated with the VTI.
- C. Domain-based- VPN domains are pre-defined for all VPN Gateways.
When the Security Gateway encounters traffic originating from one VPN Domain with the destination to a VPN Domain of another VPN Gateway, that traffic is identified as VPN traffic and is sent through the VPN Tunnel between the two Gateways. - D. Domain-based- VPN domains are pre-defined for all VPN Gateways.
A VPN domain is a service or user that can send or receive VPN traffic through a VPN Gateway.
正解：D

質問 # 70
An administrator would like to troubleshoot why templating is not working for some traffic. How can he determine at which rule templating is disabled?
- A. He can use the fw accel stat command on the gateway.
- B. He can use the fwaccel stat command on the gateway
- C. He can use the fwaccel stat command on the Security Management Server.
- D. He can use the fw accel statistics command on the gateway.
正解：B
解説：
Explanation
The fwaccel stat command on the gateway shows the status of SecureXL acceleration, including the number of accelerated and non-accelerated connections, and the reason for non-acceleration. The reason for non-acceleration can be either a rule that disables templating, or a feature that is not supported by SecureXL.
To determine which rule disables templating, the administrator can use the -s option to show the rule numbers and names. For example:
質問 # 71
An established connection is going to www.google.com. The Application Control Blade Is inspecting the traffic. If SecureXL and CoreXL are both enabled, which path is handling the traffic?
- A. Slow Path
- B. Medium Path
- C. Fast Path
- D. Accelerated Path
正解：D
解説：
Explanation
The traffic is handled by the Accelerated Path. According to the R81.x Security Gateway Architecture (Logical Packet Flow)1, the Accelerated Path is the fastest path for processing packets, as it bypasses most of the inspection and uses SecureXL to accelerate the traffic. The Accelerated Path is used for connections that are established, compliant with the security policy, and do not require any content inspection or NAT1.
The Application Control blade inspects the traffic based on the application identity, which is determined by the Application Control Software Blade in the Medium Path1. However, once the application identity is established, the connection can be offloaded to SecureXL and handled by the Accelerated Path2. This way, the Application Control blade can improve performance and reduce CPU consumption2.
The other paths are not used for this traffic because:
The Slow Path is used for packets that are not compliant with the security policy, require stateful inspection or NAT, or are not supported by SecureXL1. This path involves the most inspection and processing, and is therefore the slowest3.
The Fast Path is used for packets that are trusted and do not require any inspection or NAT. This path bypasses both SecureXL and the Firewall kernel, and uses a kernel module called simfast to forward the packets directly to the network interface driver4. This path is not enabled by default, and requires manual configuration of rules to define which traffic can use it4.
The Medium Path is used for packets that require content inspection, such as IPS, Anti-Virus, Anti-Bot, URL Filtering, or Application Control1. This path uses SecureXL to accelerate some parts of the inspection, but still involves some processing by the Firewall kernel3. This path is only used for the first few packets of a connection until the application identity is established, and then the connection can be offloaded to the Accelerated Path2.

質問 # 75
How many users can have read/write access in Gaia at one time?
- A. One
- B. Two
- C. Infinite
- D. Three
正解：A
解説：
Explanation
How many users can have read/write access in Gaia at one time? Only one user can have read/write access in Gaia at one time. This is to prevent conflicts and inconsistencies in the configuration changes made by different users. If another user tries to login with read/write access while a user is already logged in, they will receive a warning message and will be given the option to either login with read-only access or force the other user to logout. References: [Gaia Administration Guide R81], page 15.
質問 # 76
What is a best practice before starting to troubleshoot using the "fw monitor" tool?
- A. Disable SecureXL
- B. Disable CoreXL
- C. Run the command: fw monitor debug on
- D. Clear the connections table
正解：A
解説：
A best practice before starting to troubleshoot using the fw monitor tool is to disable SecureXL. SecureXL is a performance acceleration solution that optimizes the packet flow through the Security Gateway. However, SecureXL can also bypass some inspection points and cause some packets to be invisible to fw monitor. Therefore, disabling SecureXL can ensure that fw monitor captures all the relevant packets for troubleshooting purposes. Reference: Check Point Security Expert R81 Course, fw monitor, SecureXL
質問 # 77
What Factor preclude Secure XL Templating?
- A. Source Port Ranges/Encrypted Connections
- B. IPS
- C. ClusterXL in load sharing Mode
- D. CoreXL
正解：A
解説：
Explanation
SecureXL Templating is a feature that accelerates the processing of packets that belong to the same connection or session by creating a template for the first packet and applying it to the subsequent packets.
SecureXL Templating is precluded by factors that prevent the creation of a template, such as source port ranges, encrypted connections, NAT, QoS, etc. References: SecureXL Mechanism
質問 # 78
