156-315.81 Sample Questions

  1. Question 1

    Q1

    A financial services company is experiencing intermittent connectivity drops for high-volume trading applications passing through their R81.20 ClusterXL Active-Active cluster. A preliminary analysis with fw ctl pstat shows a large number of non-sticky connections. The network administrator suspects that the default load-sharing mechanism is not correctly distributing TCP connections that lack a PUSH flag in the SYN packet. Which command should be executed on the cluster members to ensure these connections are handled by the same member and become sticky?

    Show answer & explanation

    Correct answer: C

    The fwha_ls_syn_based_stickiness kernel parameter forces the cluster to make a stickiness decision based on the SYN packet alone, regardless of whether it contains a PUSH flag. This is the correct solution for ensuring TCP connections, especially from non-standard applications, are sticky and handled by a single member in an Active-Active Load Sharing cluster, preventing the described connectivity drops. The other options address different, unrelated stickiness behaviors.

  2. Question 2

    Q2Multiple answers

    A security architect is designing a security policy for a large enterprise that uses a shared services model. To improve management efficiency and policy readability, they decide to use Policy Layers. The goal is to have a baseline corporate policy applied first, followed by department-specific policies, and finally a global cleanup rule. What is the most effective way to structure the policy layers to achieve this? (Select TWO).

    Show answer & explanation

    Correct answers: A, C

    Using an Ordered Layer for the corporate baseline ensures its rules are processed first, providing a consistent security posture before any department-specific rules are considered. This is a best practice for structured policy management.

    Inline Layers are ideal for department-specific policies. A parent rule can match traffic based on source/destination (e.g., department subnets) and then direct the inspection engine to a dedicated Inline Layer for that department's specific rules. This is more efficient and scalable than creating many top-level Ordered Layers.

  3. Question 3

    Q3

    During a kernel debug session using fw ctl zdebug, an administrator observes a packet being dropped. The debug output contains the drop code fw_log_drop_ex: Packet proto=6 ... dropped by fwchain_upd_exceptions_v4 Reason: PSL Drop: ASPII_MT. What is the most likely cause of this packet drop?

    Show answer & explanation

    Correct answer: C

    The PSL Drop: ASPII_MT reason code in a kernel debug specifically indicates that the Passive Streaming Library (PSL) dropped the packet because it was matched by the Application Control & URL Filtering (ASPII) engine. MT stands for Match. This means a signature within the APPI/URLF blades caused the drop, not a standard firewall rule or state violation.

  4. Question 4

    Q4

    True or False: When configuring Management High Availability (HA), the secondary Security Management Server must be installed with the exact same version and Jumbo Hotfix Accumulator as the primary server before initiating the first manual synchronization.

    Show answer & explanation

    Correct answer: A

    This statement is true. Check Point requires that for Management HA to function correctly, both the primary and secondary management servers must be running the identical OS version, Check Point software version, and Jumbo Hotfix Accumulator. Mismatched versions will cause the synchronization to fail.

  5. Question 5

    Q5

    An administrator needs to create a scheduled task that automatically backs up the Security Management Server every Sunday at 2 AM. They want to use the most efficient, built-in method available in R81.20 SmartConsole. Which feature should they use?

    Show answer & explanation

    Correct answer: D

    The SmartTasks feature in R81 and later provides a native, GUI-based method for automating administrative tasks. It includes a built-in 'Backup Management Server' action that can be paired with a 'Time' trigger to schedule the backup without requiring any command-line scripting, making it the most efficient and recommended method.

  6. Question 6

    Q6Multiple answers

    A hospital is deploying HTTPS Inspection on its R81.20 gateways to inspect outbound traffic from clinical workstations. To comply with privacy regulations, traffic to specific financial and healthcare domains must not be decrypted. The security team also wants to ensure that if the gateway's CPU utilization for the fwk worker process exceeds 85%, HTTPS Inspection is temporarily bypassed to maintain network performance. Which two configuration steps are required to meet these requirements?

    Show answer & explanation

    Correct answers: B, C

    The HTTPS Inspection policy is the correct place to define bypass rules. Creating rules that match traffic destined for the sensitive financial and healthcare domains and setting their action to 'Bypass' will prevent decryption for compliance purposes.

    This is a specific performance-related feature within the gateway's HTTPS Inspection settings. Enabling it allows the gateway to automatically and temporarily bypass inspection when CPU load on the relevant worker processes (fwk) is high, thus preserving network availability and performance.

  7. Question 7

    Q7

    A system administrator notices that the Dynamic Dispatcher on a 16-core Security Gateway is assigning most traffic to a small subset of firewall instances, leading to high CPU on those cores while others remain underutilized. They have confirmed that SecureXL is enabled and connection templates are being used. Which CoreXL command should the administrator run to get a detailed, real-time view of the packet distribution per firewall instance (core)?

    Show answer & explanation

    Correct answer: A

    fw ctl multik stat is the correct command to display real-time statistics for CoreXL, including the number of packets being processed by each firewall instance (worker core). This output allows an administrator to immediately identify an imbalanced distribution caused by the Dynamic Dispatcher.

  8. Question 8

    Q8

    When implementing a route-based VPN (VTIs) on an R81.20 gateway, where is the encryption domain defined?

    Show answer & explanation

    Correct answer: C

    In a route-based VPN, the concept of a statically defined encryption domain is replaced by the routing table. Any traffic that is routed to the VTI by the gateway's routing table (either via static routes or a dynamic routing protocol like BGP) is considered part of the 'encryption domain' and will be encrypted and sent over the tunnel.

  9. Question 9

    Q9

    A global logistics company uses Updatable Objects to block traffic from Geo-locations known for malicious activity. The Security Management Server is in an isolated network segment with no direct internet access, but it can reach a dedicated proxy server. How must the administrator configure the Security Gateway and Management Server to allow the Updatable Objects to be updated successfully?

    graph TD Internet((Internet)) --> Proxy[Proxy Server] subgraph DMZ Proxy end subgraph MgmtNet [Management Network] SMS[Security Management Server] end subgraph InternalNet [Internal Network] GW[Security Gateway] end SMS --> Proxy GW --> Internet

    Show answer & explanation

    Correct answer: A

    The Security Management Server is responsible for downloading updates for Updatable Objects from Check Point's cloud services. In an environment where the SMS has no direct internet, it must be configured to use a proxy. This is done in the Gaia Portal of the SMS. Once the SMS downloads the updates, it distributes them to the managed Security Gateways during policy installation. The gateways themselves do not need direct internet or proxy access for this specific feature.

  10. Question 10

    Q10

    Case Study

    A retail corporation, 'GlobalMart', is upgrading its security infrastructure to a distributed R81.20 environment. They have two primary data centers (DC-A and DC-B) which will each host a Security Management Server in a Management High Availability (HA) configuration. The Primary SMS will be in DC-A, and the Secondary SMS will be in DC-B. A dedicated Log Server will also be deployed in each data center, and gateways will be configured to send logs to their local Log Server.

    Current Situation: All management components are currently on a single R80.40 server. The network team has provisioned new appliances for the R81.20 upgrade. The data centers are connected via a high-speed, low-latency WAN link. The primary goal is to ensure management redundancy and localized logging to reduce WAN traffic, with seamless failover in case the primary data center becomes unavailable.

    Requirements:

    1. Establish a resilient Management HA pair between DC-A and DC-B.
    2. Security Gateways in DC-A must log to the Log Server in DC-A. Gateways in DC-B must log to the Log Server in DC-B.
    3. In the event of a failure of the Log Server in DC-A, the DC-A gateways must automatically start sending logs to the Log Server in DC-B.
    4. The solution must be configured following Check Point best practices for performance and redundancy.

    Which configuration approach best satisfies all of GlobalMart's requirements?

    Show answer & explanation

    Correct answer: D

    This is the Check Point best practice for achieving logging redundancy. By creating a Log Server Cluster object and adding both Log Servers to it, the gateways can be configured to send logs to the cluster. This abstraction layer handles the failover automatically. If the primary defined logger (the local one) fails, the gateway will seamlessly redirect its logs to the other member of the cluster (the remote one), fulfilling all requirements without manual intervention.
