156-315.81.20 Practice Test 10 — 10 Questions

Question 1

An administrator is deploying a Route-Based VPN between two Check Point R81 Security Gateways to support dynamic routing over the tunnel. After configuring the VPN community as a Route-Based VPN type, the administrator notices that traffic is not being encrypted. What is the most likely reason?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

The administrator did not configure a Virtual Tunnel Interface (VTI) and corresponding routes.. In a Route-Based VPN, Check Point uses Virtual Tunnel Interfaces (VTIs) to route traffic into the VPN tunnel. The administrator must create a VTI on each gateway and configure routing to direct traffic for the remote encryption domain into that interface. Without the VTI and appropriate routes, traffic will not be encrypted, even if the VPN community is configured correctly.

Answer

The administrator did not configure NAT for the VPN traffic.

Answer

The administrator did not enable IPsec on the Security Gateways.

Answer

The VPN community was not configured with the correct encryption domain.

Question 2

A security administrator is upgrading a Security Gateway from R80.40 to R81.20. After the upgrade, the administrator notices that the gateway's management connection is lost, and the gateway is not responding to pings. The administrator can access the gateway via the console. What is the most likely cause of this issue?

Accepted Answer

The network interface configuration was not preserved during the upgrade, and the management interface is down.. After an upgrade, losing management connectivity while console access remains available often points to a network interface problem. The management interface may have failed to initialize properly, or its configuration might have been altered. Checking interface status via console and re-enabling it if necessary is the appropriate troubleshooting step. Other causes like policy or IP changes are less likely in this scenario.

Answer

The upgrade process changed the default gateway IP address.

Answer

The firewall policy was not installed after the upgrade, causing the gateway to block all traffic.

Answer

The upgrade failed and the gateway is still running the old version.

Question 3

A Check Point R81 gateway is using Threat Emulation. An administrator observes that a PDF file was emulated, and the log shows the verdict as 'Malicious'. However, the user was able to open the file without any warning. What is the most likely cause of this behavior?

Accepted Answer

The Threat Emulation blade was configured in 'Detect' mode instead of 'Prevent' mode.. The most likely cause is that Threat Emulation is configured in Detect mode, which only logs malicious files without blocking them. This allows users to open the file despite the malicious verdict. Switching to Prevent mode would block the file and prevent user access, aligning with the security policy.

Answer

The PDF file was corrupted and could not be executed, so it was allowed.

Answer

The file was downloaded over HTTPS, which bypasses Threat Emulation.

Answer

The user has administrative privileges and overrode the block.

Question 4

An administrator is tuning a Security Gateway with CoreXL enabled. The administrator notices that the 'fw_worker' processes are evenly distributed across cores, but overall throughput is lower than expected. After checking SecureXL, the administrator finds that a significant portion of traffic is not being accelerated. Which of the following is the most likely cause for this performance bottleneck?

Accepted Answer

The SecureXL templates are disabled.. The most likely cause is that SecureXL templates are disabled. Templates allow SecureXL to accelerate common traffic patterns by pre-compiling the processing steps. When disabled, more traffic is passed to the Firewall path, increasing CPU usage on CoreXL workers and reducing overall throughput. Even with even core distribution, the workers become overloaded, leading to lower performance.

Answer

The network interface does not support hardware acceleration.

Answer

CoreXL is configured with more instances than CPU cores.

Answer

The firewall kernel is not compiled with SecureXL support.

Question 5

A Check Point administrator is designing a hub-and-spoke VPN community where all branch offices must communicate through the central gateway. The administrator wants to ensure that traffic between spokes is routed via the hub without requiring direct tunnels. Which Check Point VPN community configuration achieves this?

Accepted Answer

Configure the community as 'Star' topology with the central gateway as the center and branch gateways as satellites.. In Check Point VPN community design, a Star topology explicitly defines a central gateway and satellite gateways. Satellites only build tunnels to the center, ensuring all inter-spoke traffic traverses the hub. This is the standard way to implement hub-and-spoke VPNs and centralize security policy enforcement.

Answer

Enable 'Mesh' topology in the VPN community, allowing all gateways to establish direct tunnels with each other.

Answer

Set the VPN domain of each branch gateway to include all other branch networks, enabling direct tunnels.

Answer

Use 'Remote Access' community type, which automatically routes all inter-branch traffic through the central gateway.

Question 6

A security administrator is deploying a ClusterXL High Availability cluster and needs to ensure that the cluster will successfully synchronize kernel tables between members. Which two conditions are required for successful synchronization? (Choose two.)

Accepted Answer

The synchronization interface must be configured and reachable between members.. Successful ClusterXL synchronization requires a dedicated, reachable synchronization interface and identical software versions and hotfix levels on all members. These conditions ensure that kernel table updates can be transmitted and interpreted correctly. Hardware differences and management server placement do not affect synchronization, and not all interfaces need to be on the same broadcast domain.

Answer

The cluster members must have identical hardware specifications.

Answer

The cluster members must be connected to the same broadcast domain on all interfaces.

Answer

The management server must be a member of the cluster.

Question 7

A security engineer is configuring a ClusterXL High Availability cluster with two members. The cluster is operational, but the engineer wants to ensure that the Active member can detect a failure of the Standby member's synchronization path. Which interface should be configured as the synchronization network?

Accepted Answer

A dedicated, high-speed interface (e.g., 10GbE) directly connected or on a dedicated VLAN. Synchronization in ClusterXL High Availability demands a dedicated, high-speed link to handle the continuous flow of state information. A dedicated interface, whether directly connected or on a dedicated VLAN, provides the necessary bandwidth and isolation, ensuring that synchronization traffic does not compete with production traffic and that failover remains stateful and timely.

Answer

The management interface (eth0) on each member

Answer

Any interface that is part of the same subnet as the cluster VIP

Answer

A dedicated interface on each member connected to a separate switch

Question 8

An administrator is troubleshooting why Threat Emulation is not inspecting files downloaded over HTTPS. The gateway is configured with HTTPS Inspection, but files are still bypassing emulation. What is the most likely cause?

Accepted Answer

The HTTPS Inspection policy is not configured to inspect the relevant category or site.. For Threat Emulation to inspect files over HTTPS, HTTPS Inspection must be enabled and the policy must include the relevant traffic. If the policy does not cover the sites or categories, traffic bypasses inspection, and files are not emulated. Other options are either limitations that do not exist or are less likely given the scenario.

Answer

The gateway's HTTPS Inspection certificate is not trusted by the clients.

Answer

Threat Emulation does not support files downloaded over HTTPS.

Answer

Threat Emulation is only applied to HTTP traffic by default.

Question 9

A Check Point administrator is troubleshooting a Threat Emulation issue where a specific PDF file was not emulated, despite the Threat Prevention policy being configured to inspect PDFs. The log shows the file was allowed with the action 'Bypass' under Threat Emulation. The administrator verifies that the file is not password-protected and is under the maximum file size limit. What is the most likely reason for the bypass?

Accepted Answer

The file hash was found in the ThreatCloud whitelist, so emulation was skipped.. A 'Bypass' action in Threat Emulation logs often occurs when the file's hash is found in the ThreatCloud whitelist, indicating it is known to be benign. This avoids unnecessary emulation and reduces latency. Other common bypass reasons include unsupported file types, password-protected files, or files that exceed size limits, but those are ruled out by the scenario. Therefore, the whitelist is the most likely cause.

Answer

The PDF contained embedded JavaScript, which Threat Emulation cannot inspect.

Answer

The Threat Emulation blade was not enabled on the Security Gateway.

Answer

The PDF file was too large and exceeded the maximum file size for emulation.

Question 10

A network administrator is configuring Identity Awareness on a Security Gateway using AD Query. The administrator wants to ensure that user identities are correctly associated with IP addresses and that the gateway can resolve user group memberships for policy enforcement. Which component must be installed and configured on the Security Gateway to enable AD Query?

Accepted Answer

Check Point AD Query configuration in the Identity Awareness blade. AD Query is a transparent identification method where the Security Gateway queries Active Directory domain controllers to learn user logon events and group memberships. It is configured within the Identity Awareness blade on the gateway and does not require any client-side software. The Identity Agent, Captive Portal, and Terminal Server Agent are separate identification methods used in different scenarios. For AD Query, only the gateway configuration and proper permissions to query AD are needed.

Answer

Check Point Identity Agent

Answer

Check Point Terminal Server Agent

Answer

Check Point Captive Portal
