156-315.81.20 Sample Questions

  1. Question 1

    Q1

    A global logistics company is deploying Check Point Maestro in a dual-site configuration for disaster recovery. The primary site has 10 Security Gateway Appliances (SGAs) and the secondary site has 8 SGAs. The network architect wants to ensure that if the primary site fails, traffic is seamlessly handled by the secondary site. A key requirement is to maintain symmetric routing for stateful inspection. Which Maestro and ClusterXL feature is specifically designed to manage asymmetric traffic in a dual-site deployment?

    Show answer & explanation

    Correct answer: D

    In a Maestro dual-site deployment, asymmetric routing is a common challenge where a packet may enter through the primary site and the return packet may try to exit through the secondary site. To maintain stateful inspection, the return packet must be processed by the same gateway. Maestro's Connection Stickiness (also known as 'Follow Me') feature, managed under a Single Management Object (SMO), ensures that once a connection is assigned to a specific site, all subsequent packets for that connection are forwarded to that original site for processing, thereby solving the asymmetric routing problem.

  2. Question 2

    Q2Multiple answers

    During a security audit, it was discovered that a high-volume of encrypted DNS traffic (DNS over TLS) is bypassing inspection, creating a potential channel for data exfiltration. The security manager has tasked you with implementing a solution using R81.20 features to gain visibility and apply threat prevention to this traffic without disrupting legitimate DNS resolution for clients. Which TWO of the following actions should be taken to achieve this? (Select TWO)

    Show answer & explanation

    Correct answers: B, C

    DNS over TLS (DoT) standardly uses TCP port 853. To intercept and inspect this encrypted traffic, a specific HTTPS Inspection rule must target this port.

    Once the traffic is decrypted by the HTTPS Inspection rule, a corresponding Threat Prevention policy rule is needed to apply security profiles (like IPS, Anti-Bot, and Anti-Virus) to the now-visible DNS queries.

  3. Question 3

    Q3

    True or False: In a Check Point R81.20 ClusterXL High Availability deployment, enabling the 'Same VMAC' feature eliminates the need for Address Resolution Protocol (ARP) updates to be sent to the network switches upon a cluster failover.

    Show answer & explanation

    Correct answer: A

    The 'Same VMAC' feature, introduced in R81.20, allows all members of a cluster to use the same Virtual MAC address for cluster interfaces. Because the MAC address does not change during a failover, the upstream switch's MAC address table does not need to be updated. This eliminates the dependency on gratuitous ARPs (GARPs) for failover, resulting in faster and more reliable failover events, especially in complex switched environments or public clouds where GARP is not supported.

  4. Question 4

    Q4

    A financial services company is using an R81.20 Security Gateway to protect its algorithmic trading platform, which relies on extremely low-latency multicast data feeds. The security administrator has noticed that under heavy load, some multicast packets are being dropped, causing significant financial impact. A performance analysis reveals that the drops are occurring within the firewall kernel during PIM (Protocol Independent Multicast) processing. The administrator needs to implement a solution that bypasses kernel-level PIM processing for trusted, high-volume multicast streams to ensure the lowest possible latency.

    Which R81.20 Advanced Routing feature should be configured to address this specific requirement?

    Show answer & explanation

    Correct answer: C

    The IPv6 Static Multicast Forwarding Cache (MFC) is a feature in R81.20 designed for exactly this use case. It allows an administrator to manually create forwarding entries for specific multicast groups. This enables the forwarding of multicast data without requiring any PIM configuration or processing in the kernel. By creating a static MFC entry, the gateway can forward the trusted, high-volume multicast streams at line rate, significantly reducing latency and preventing drops associated with dynamic PIM processing.

  5. Question 5

    Q5

    Case Study

    Company Background:
    MedPro Clinics, a large healthcare provider, operates a central data center and numerous remote clinics. They rely on an R81.20 Multi-Domain Security Management (MDS) environment to manage security policies. The MDS server at the data center manages individual Domain Management Servers (DMS) for different regions. Each clinic connects to the data center via a site-to-site VPN tunnel terminated on a local Check Point gateway.

    Current Situation:
    MedPro is experiencing performance issues with policy installations and log indexing on the central MDS server. The audit team has also raised concerns about the lack of granular administrative control, as global administrators currently have access to all regional domains. Furthermore, a recent incident at one clinic went unnoticed for hours because logs were only being analyzed at the central data center, causing a delay in response.

    Requirements:

    1. Improve policy installation and log processing performance across the entire environment.
    2. Implement a more granular administrative model to restrict access based on an administrator's region.
    3. Enable faster, localized threat detection and reporting at the regional level.
    4. The solution must integrate with the existing Multi-Domain Security Management architecture.

    Proposed Solution:
    The lead security architect proposes a significant change to the MDS architecture. The plan is to deploy dedicated servers at each regional headquarters to handle specific management tasks, offloading the central MDS. The goal is to create a more distributed and resilient management infrastructure.

    Which architectural component should be deployed at each regional headquarters to meet all of MedPro's requirements?

    Show answer & explanation

    Correct answer: C

    Deploying a regional Log Server and SmartEvent Server combination addresses all requirements. 1) It offloads log processing and indexing from the central MDS, improving its performance and speeding up policy installations. 2) The central MDS can still be used to define granular permissions, allowing regional administrators to be assigned roles that only grant access to their specific regional SmartEvent server. 3) A local SmartEvent server provides immediate, localized threat analysis and reporting for the region, enabling faster incident detection and response. This solution creates a distributed logging and event management architecture that fully integrates with the central MDS.

  6. Question 6

    Q6

    A system administrator is analyzing the output of fw ctl pstat on an R81.20 Security Gateway experiencing high CPU utilization. They need to understand the relationship between the SecureXL, Medium Path, and Firewall Path (Slow Path). The following ASCII diagram illustrates the packet processing flow:

    Packet IN
    |
    v
    +---------------+
    | SecureXL | --- (Accelerated Path) --> Packet OUT
    +---------------+
    |
    v
    +---------------+
    | Medium Path |
    | (Passive Str.)| --- (Inspection) -------> SecureXL Template -> Packet OUT
    +---------------+
    |
    v
    +---------------+
    | Firewall Path |
    | (Slow Path) | --- (Full Inspection) ---> Medium Path -> Packet OUT
    +---------------+
    

    Based on the diagram and Check Point's performance tuning architecture, which statement accurately describes the HyperFlow feature's role?

    Show answer & explanation

    Correct answer: C

    HyperFlow is designed to optimize the handling of 'elephant flows'—very long, high-bandwidth connections. Normally, a single connection is processed by a single CoreXL firewall instance (Firewall Path). For an elephant flow, this can create a bottleneck on that one CPU core. HyperFlow detects these flows and dynamically assigns additional CoreXL instances (and thus, more CPU cores) to process the same connection in parallel, significantly increasing throughput for that flow and preventing a single core from being overloaded.

  7. Question 7

    Q7

    An administrator is configuring a new R81.20 cluster and wants to use the migrate_server command to export the configuration from an existing R81 Security Management Server. The goal is to perform a clean installation on new hardware and then import the configuration. What is the correct command syntax to initiate the export process on the source Security Management Server?

    Show answer & explanation

    Correct answer: C

    The migrate_server command is the correct tool for this task. The proper syntax requires the export argument followed by the desired path and filename for the output archive. This command packages the entire management database, objects, policies, and settings into a single .tgz file that can be used with migrate_server import on the new server.

  8. Question 8

    Q8

    A DevOps team requires the ability to programmatically add and remove IP addresses from a security policy rule that grants access to a staging environment. They want to avoid giving the team SmartConsole access and need a solution that allows for rapid, automated updates without requiring a full policy installation for every change. Which R81.20 object type is best suited to meet these requirements?

    Show answer & explanation

    Correct answer: B

    Network Feed Objects (a type of Updatable Object) are specifically designed for this purpose. They allow a Security Gateway to pull a list of IPs, domains, or other indicators from an external web server. The DevOps team can manage a simple text file on a web server, and the gateway will periodically fetch and enforce it. This process is handled directly on the gateway and does not require a policy installation for updates, enabling rapid and automated changes.

  9. Question 9

    Q9

    A security engineer is troubleshooting a site-to-site VPN between an R81.20 Security Gateway and a third-party cloud provider. The cloud provider requires IKEv2 and mandates the use of specific, strong cryptographic algorithms for both IKE and IPsec phases. The engineer observes in the logs that the tunnel fails to establish during Phase 2 negotiations. The error message indicates a 'NO_PROPOSAL_CHOSEN' payload. What is the most likely cause of this issue?

    Show answer & explanation

    Correct answer: C

    The 'NO_PROPOSAL_CHOSEN' error message during IKE Phase 2 (for IPsec SAs) or Phase 1 (for IKE SAs) specifically means that the peers could not agree on a common set of cryptographic algorithms. The initiating peer sends a proposal with a list of supported ciphers (e.g., AES-256 for encryption, SHA-256 for integrity), and the responding peer must find at least one matching set that it is also configured to use. If no match is found, this error is returned. The engineer must verify the VPN community's IPsec and IKE properties to ensure they align with the cloud provider's mandate.

  10. Question 10

    Q10Multiple answers

    A retail company is expanding its use of IoT devices, including PoS terminals and inventory scanners. These devices communicate with cloud services over HTTPS. The security team needs to enforce a strict security policy that allows these devices to communicate ONLY with necessary, predefined FQDNs. They also need to apply IPS protections to this traffic. The solution must not rely on maintaining static IP lists for the cloud services and must be efficient.

    Which THREE Check Point features should be combined in the policy to achieve this? (Select THREE)

    Show answer & explanation

    Correct answers: B, C, D

    To apply IPS to encrypted HTTPS traffic, the gateway must first decrypt it. HTTPS Inspection is the feature that performs this decryption and re-encryption, making the payload visible to the IPS engine.

    Using Domain Objects allows the administrator to specify FQDNs in the policy. The gateway dynamically resolves these FQDNs to IPs and updates the policy accordingly. This is the correct way to control access to services with dynamic IPs without manual intervention.

    After the Access Control rule allows the connection and HTTPS Inspection decrypts it, a Threat Prevention rule is required to apply the IPS profile to the decrypted traffic, fulfilling the requirement to inspect for threats.
