156-315.81.20 Practice Test 4 — 25 Questions

Question 1

A security administrator is troubleshooting a performance issue on an R81 Security Gateway. The administrator runs 'fwaccel stats -s' and observes that a large number of connections are being handled by the Firewall path instead of being accelerated. The administrator wants to identify which specific connections are not being accelerated. Which command should be used to view the acceleration status of active connections?

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

Accepted Answer

fwaccel conns. To identify which specific connections are not being accelerated, the administrator must view the SecureXL connection table. The 'fwaccel conns' command lists active connections and indicates whether each is accelerated or handled by the Firewall path. This granular view is essential for troubleshooting why certain traffic bypasses acceleration, as it provides details like source, destination, and the reason for non-acceleration.

Answer

fwaccel stats

Answer

fw monitor -e 'accel;'

Answer

cpview -t

Question 2

An administrator is preparing to upgrade a Security Gateway from R80.40 to R81.20 using the CPUSE Web UI. Before initiating the upgrade, the administrator wants to ensure that all required packages are available and that the repository is up to date. Which action should the administrator take first?

Accepted Answer

In the CPUSE Web UI, click 'Check for Updates' to refresh the repository and list available packages.. Before upgrading, the administrator must ensure that the CPUSE repository is current. The CPUSE Web UI provides a 'Check for Updates' button that queries Check Point's servers for the latest packages, including the R81.20 upgrade package and required hotfixes. This step ensures that the correct packages are available for the upgrade, avoiding failures due to missing or outdated files. It is a best practice to perform this check before any upgrade.

Answer

Run 'yum update' to update the underlying operating system packages.

Answer

Manually download the R81.20 upgrade package from the Check Point Support Center and upload it via SCP.

Answer

Run 'cpuse fetch' from the command line to download the latest packages.

Question 3

A security administrator is configuring a Remote Access VPN with Endpoint Security VPN clients. The requirement is that all client traffic, including Internet-bound traffic, must be inspected by the gateway's Threat Prevention blades before reaching its destination. Which client configuration setting should the administrator enable?

Accepted Answer

Enable 'Route all traffic to gateway' in the VPN client's advanced settings.. To have the gateway inspect all client traffic, the client must route everything into the tunnel. The 'Route all traffic to gateway' option creates a full-tunnel configuration, ensuring that Internet-bound packets reach the Security Gateway where Threat Prevention and other blades can inspect them before forwarding.

Answer

Configure the client to use 'Hub Mode' with a dedicated gateway cluster.

Answer

Enable 'Allow split tunneling' and define the corporate subnet as the only encrypted route.

Answer

Enable 'Visitor Mode' on the gateway so clients connect over a single port.

Question 4

A Security Gateway is configured with Identity Awareness using AD Query, and users authenticate to the domain normally. An administrator notices that identities for users who log on to workstations on a remote subnet are not appearing in the Identity Awareness database, while local subnet users are identified correctly. The domain controllers are reachable and audit logging is enabled. Which configuration item should the administrator verify first?

Accepted Answer

The remote subnet is included in the AD Query configuration's monitored networks. AD Query filters the domain controller logon events it consumes based on the configured monitored networks. A subnet that is not listed produces no identities for its users, even when domain controllers and auditing are healthy. Verifying that the remote subnet appears in the AD Query network list is the direct and most likely fix for this selective failure.

Answer

The Captive Portal certificate is trusted by the remote workstations

Answer

The gateway's identity sharing setting is set to 'Sharing to all gateways'

Answer

The gateway's DNS resolver is configured to query the domain controllers

Question 5

An administrator is analyzing the performance of a Security Gateway with CoreXL and SecureXL enabled. The administrator notices that certain types of traffic, such as VoIP and streaming media, are not being accelerated by SecureXL. Which of the following is the most likely reason for this behavior?

Accepted Answer

The traffic requires deep packet inspection by the firewall.. Traffic that requires deep packet inspection, such as VoIP and streaming media subject to IPS or application control, cannot be accelerated by SecureXL. These advanced security features require full firewall processing, so SecureXL bypasses them. This is a common reason for selective non-acceleration, as SecureXL is designed to offload only simple, stateless packet handling.

Answer

The SecureXL templates for UDP are disabled by default.

Answer

CoreXL is not configured to handle UDP traffic.

Answer

SecureXL does not accelerate UDP traffic.

Question 6

A Check Point Security Gateway is experiencing high CPU utilization on a single core, while other cores are underutilized. CoreXL is enabled, and the administrator suspects that the traffic is not being distributed evenly across the CoreXL firewall instances. Which command should the administrator use to verify the distribution of connections across CoreXL instances?

Accepted Answer

fw ctl multik stat. To verify the distribution of connections across CoreXL instances, the administrator should use 'fw ctl multik stat'. This command provides per-instance statistics, including the number of connections and packets, allowing the administrator to see if the load is balanced. If one instance is handling more traffic, it may indicate a configuration issue or a traffic pattern that is not being hashed evenly. The other commands provide different information, such as SecureXL statistics or thread-level CPU usage, which are not specific to CoreXL instance distribution.

Answer

fw ctl multik print_instances

Answer

top -H

Answer

fwaccel stats -s

Question 7

A security administrator is deploying a new ClusterXL High Availability cluster with two members. The administrator needs to ensure that the cluster can properly synchronize state and perform failover. Which two actions are required to configure the synchronization network? (Choose two.)

Accepted Answer

Assign a dedicated interface on each member for synchronization and configure it with a unique IP address on each member.. To configure the synchronization network in a ClusterXL High Availability cluster, each member needs a dedicated interface with a unique IP address, and this network should be separate from the data network to avoid interference. Using the same IP address, enabling VRRP, or configuring a virtual IP on the sync interface are incorrect and can cause communication failures or unnecessary complexity.

Answer

Configure the synchronization interface as a cluster interface with a virtual IP address.

Answer

Enable VRRP on the synchronization interface to provide redundancy.

Answer

Configure the synchronization interface to use the same IP address on both members.

Question 8

A Security Administrator is configuring a new ClusterXL High Availability cluster with two members. The administrator wants to ensure that if the active member fails, the standby member takes over within the shortest possible time. Which ClusterXL mechanism is responsible for detecting a failure of the active member and triggering the failover?

Accepted Answer

Cluster Control Protocol (CCP) heartbeats exchanged over the synchronization network and cluster interfaces.. ClusterXL High Availability uses Cluster Control Protocol (CCP) heartbeats to monitor member health. These heartbeats are exchanged over the synchronization network and cluster interfaces, allowing the standby member to detect when the active member fails and to take over. Other protocols like VRRP, SNMP, or ICMP are not the internal failure detection mechanism for ClusterXL.

Answer

Simple Network Management Protocol (SNMP) traps generated by the active member.

Answer

Virtual Router Redundancy Protocol (VRRP) advertisements sent by the active member.

Answer

Internet Control Message Protocol (ICMP) pings sent between cluster members.

Question 9

An administrator is troubleshooting an Identity Awareness deployment where users authenticated through a Captive Portal are shown as unidentified on a different Security Gateway in the same distributed environment. The portal gateway correctly identifies the users, but the second gateway does not. Which action should the administrator take to allow the identity information to reach the second gateway?

Accepted Answer

Configure Identity Sharing on the portal gateway to share identities with the second gateway. Identity Sharing is the feature that lets one gateway publish the identities it has learned so that peer gateways can use them for policy enforcement. When users are identified at the portal gateway but unknown at another gateway, enabling and correctly scoping Identity Sharing from the acquiring gateway to the peer is the direct fix.

Answer

Enable AD Query on the second gateway and point it at the same domain controllers

Answer

Add the second gateway's internal interface to the Captive Portal configuration

Answer

Configure the second gateway as a Secondary Security Management Server

Question 10

An administrator is deploying a new R81.20 Security Gateway using the Gaia First Time Configuration Wizard. The organization requires the gateway to obtain its IP address dynamically from the corporate DHCP server, but the administrator also needs to ensure the gateway can be reached at a predictable address for management. Which configuration should the administrator select during the wizard?

Accepted Answer

Use DHCP and configure a DHCP reservation on the DHCP server for the gateway's MAC address.. The requirement is twofold: obtain an IP dynamically via DHCP and ensure the gateway remains reachable at a predictable address. A DHCP reservation on the server side achieves both by binding a specific IP to the gateway's MAC address, so the gateway still uses DHCP but always receives the same address. This is the standard method for combining dynamic configuration with stable management access.

Answer

Configure a static IP address manually on the management interface.

Answer

Configure a secondary IP address on the management interface using an alias.

Answer

Use DHCP and rely on DNS dynamic updates to resolve the gateway's hostname.

Question 11

An administrator is upgrading a Security Gateway using CPUSE. The pre-upgrade verification fails with the error 'Unsupported configuration: IPv6 is enabled on interface eth0'. What is the most appropriate action to resolve this?

Accepted Answer

Disable IPv6 on eth0 using the Gaia Portal or CLI before re-running the upgrade.. The pre-upgrade verification fails because IPv6 is enabled on eth0, which is unsupported for the upgrade. The correct resolution is to disable IPv6 on that interface using Gaia tools. This ensures the configuration meets the upgrade requirements and allows the process to proceed without errors.

Answer

Ignore the warning and proceed with the upgrade, as IPv6 is not used in the environment.

Answer

Upgrade the gateway to an intermediate version that supports IPv6 before upgrading to R81.20.

Answer

Remove the IPv6 address from eth0 but leave IPv6 enabled globally.

Question 12

A security administrator manages a two-member ClusterXL High Availability cluster running R81.10. The primary member fails and the secondary takes over. After the primary is repaired and rejoins, the administrator wants to verify which member is currently active and which is standby, and confirm that the failover completed cleanly. Which command should be run on either member to display the current cluster state and member roles?

Accepted Answer

cphaprob stat. To confirm the current ClusterXL role of each member after a failover, the administrator needs a command that reports live cluster state. cphaprob stat outputs the local member's state (Active/Standby), the cluster mode, and the identity of the active member, providing exactly the post-failover confirmation required.

Answer

cpstat ha

Answer

fw ctl pstat

Answer

cpconfig

Question 13

A security administrator is configuring Threat Prevention on a R81.20 Security Gateway. They enable Threat Emulation for incoming files and want to reduce the gateway's CPU load by having emulation performed by a dedicated appliance rather than the gateway itself. Which Check Point component should they deploy and configure to achieve this?

Accepted Answer

Threat Emulation appliance (SandBlast TE2500). The dedicated Threat Emulation appliance is designed to offload emulation from Security Gateways, reducing their CPU load. The other options either are cloud-based, do not perform emulation, or are endpoint-focused, and thus do not meet the requirement of a dedicated appliance for gateway offload.

Answer

Check Point SandBlast Agent

Answer

ThreatCloud Emulation service

Answer

Security Management Server

Question 14

A security administrator is setting up a VPN community between two Check Point Security Gateways using IKEv2. The administrator wants to ensure that the gateways authenticate each other using certificates. What must be configured on both gateways to enable certificate-based authentication?

Accepted Answer

A valid certificate from a trusted Certificate Authority. To enable certificate-based authentication in an IKEv2 VPN community, each gateway must have a valid certificate issued by a trusted Certificate Authority. The gateways exchange these certificates during IKE negotiation and verify them against the trusted CA, providing mutual authentication without relying on pre-shared secrets.

Answer

A VPN tunnel interface

Answer

A shared secret key

Answer

Pre-shared secret

Question 15

An administrator is troubleshooting a performance degradation on a Check Point Security Gateway. The administrator suspects that SecureXL is not accelerating traffic as expected. Which two actions should the administrator take to verify and potentially resolve the issue? (Choose two.)

Accepted Answer

Run 'fwaccel conns' to identify non-accelerated connections.. To verify and resolve SecureXL acceleration issues, the administrator should first confirm that SecureXL is enabled using 'fwaccel stat'. Then, using 'fwaccel conns', the administrator can identify which connections are not accelerated and why. These two actions provide the necessary information to diagnose the problem and take corrective measures, such as enabling SecureXL or adjusting policy to allow acceleration.

Answer

Disable CoreXL to force all traffic through SecureXL.

Answer

Increase the number of CoreXL instances to improve SecureXL acceleration.

Answer

Check the SecureXL templates status with 'fwaccel templates'.

Question 16

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?

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 17

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 18

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 19

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 20

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.
