156-215.81.20 Hard Questions — 25 Difficult Questions

Question 1

An administrator needs to reset Secure Internal Communication (SIC) on a remote Security Gateway that is currently showing a status of 'Communication Error' in SmartConsole. Which TWO actions must be performed to successfully re-establish the SIC relationship? (Choose TWO)

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

Accepted Answer

Run cpconfig on the Security Gateway, select the option to reset SIC, and provide a new activation key.. Resetting SIC requires coordination between the Security Management Server database object and the remote gateway operating system. The administrator must initiate the reset state on both ends using the cpconfig utility on the gateway and re-defining the matching activation key within SmartConsole.

Answer

Execute the fwm unloadlocal command directly on the Security Gateway CLI before generating new certificates.

Answer

Restart the database daemon on the management server using cpstop and cpstart commands.

Answer

Reboot the Security Gateway immediately after generating the internal Certificate Authority files.

Question 2

Refer to the exhibit. An administrator encounters this error when attempting to install a policy. What is the underlying cause?

Accepted Answer

The system clock on the Security Gateway is significantly drifted.. Certificate Revocation Lists (CRL) are used by gateways to verify the validity of the Management Server's certificate. When the CRL expires, the gateway can no longer trust the certificate issued by the SMS, causing the SIC channel to drop for security reasons. This is a common maintenance issue; administrators must ensure the SMS can access CRL distribution points or manually update the local CRL repository to restore trust.

Answer

The license on the Security Gateway has expired.

Answer

The Management Server has a revoked certificate in its database.

Answer

The SIC password requires a mandatory update.

Question 3

Refer to the exhibit. An administrator gets 'Connection refused'. What is the most likely culprit?

Accepted Answer

A firewall rule is dropping port 18211 traffic.. A 'Connection refused' error typically implies that the TCP connection is being actively rejected by the target server or a device in the path. In the context of SIC, this means the port 18211 is either closed on the management server or blocked by a local firewall rule on the gateway or an intermediate network device, preventing the handshake from even initiating.

Answer

The ICA certificate is expired.

Answer

The SIC activation key is incorrect.

Answer

The Management Server has a corrupted SIC database.

Question 4

What happens if the 'sic_reset' command is executed on a gateway without performing the corresponding steps on the Management Server?

Accepted Answer

The management server will reject all future policy installs.. Executing 'sic_reset' on the gateway wipes the local SIC identity. However, the management server still has the old certificate associated with that gateway. Consequently, the management server will reject all future connection attempts from the gateway because the certificate presented by the gateway no longer matches the one stored in the management server's database, leading to a complete management lockout.

Answer

The Management Server automatically deletes the old entry.

Answer

The gateway remains manageable for 24 hours.

Answer

The gateway reverts to its factory default settings.

Question 5

When configuring a Static NAT rule, why is it recommended to use a 'Static' NAT object rather than just defining the IP addresses manually in the rule?

Accepted Answer

It enables automatic Proxy ARP updates.. Using a NAT object (e.g., a host object with Automatic NAT enabled) is best practice because it centralizes the configuration. It ensures that the NAT setting is consistent whenever that object is used in a policy. Manually defining IPs in rules can lead to configuration drift, increased risk of human error, and difficulty in auditing or updating NAT settings during network changes.

Answer

It is required for the policy to be pushed to the gateway.

Answer

It improves the performance of the NAT engine.

Answer

It is the only way to support non-TCP protocols.

Question 6

Which TWO of the following statements are correct regarding the order of NAT processing in a Check Point Security Policy?

Accepted Answer

Manual NAT rules are evaluated in a top-down order.. NAT processing in Check Point follows a specific hierarchy where Automatic NAT (configured within the object) is evaluated before Manual NAT rules. Furthermore, the order of rules in the Manual NAT policy is top-down, similar to the Access Control Policy. Understanding this sequence is vital for ensuring that traffic is translated correctly, especially when overlapping rules or specific host exceptions exist within the environment.

Answer

Automatic NAT rules are processed after all Manual NAT rules.

Answer

Automatic NAT is ignored if a Manual NAT rule matches.

Answer

Manual NAT rules are processed before Automatic NAT rules.

Question 7

When utilizing NAT in a High Availability (HA) cluster, what must be considered regarding Proxy ARP?

Accepted Answer

Proxy ARP must be configured on all cluster members.. In an HA cluster, Proxy ARP entries must be synchronized so that if a failover occurs, the secondary gateway can immediately start responding to ARP requests for the NAT IP. If Proxy ARP is not handled correctly, the failover would result in a black hole for traffic destined to the NAT IP, as no device would claim the traffic.

Answer

Proxy ARP is managed per-node, not globally.

Answer

Proxy ARP is only supported on the active node.

Answer

NAT cannot be used in High Availability setups.

Question 8

Which THREE conditions are required for a successful Hide NAT configuration on a Check Point gateway?

Accepted Answer

The NAT blade must be enabled on the security gateway object.. A successful Hide NAT configuration requires a defined NAT rule, a valid address pool (usually the gateway external IP), and correct routing. The gateway must also have the NAT blade enabled. If any of these components are missing, the translation will fail, resulting in dropped packets or traffic that is not source-natted, potentially exposing internal network information to external entities.

Answer

The internal hosts must have a public IP address.

Answer

The Security Policy must explicitly allow the translated destination IP.

Question 9

Which THREE of the following are prerequisites for effective Application Control and URL Filtering?

Accepted Answer

HTTPS Inspection enabled for encrypted traffic.. For Application Control and URL Filtering to function correctly, the gateway needs to see the traffic, identify the traffic, and have the latest intelligence on the traffic. These prerequisites ensure that the security policy is applied accurately and that the gateway can distinguish between legitimate traffic and potential threats, which is foundational to the security architecture of Check Point's Next Generation Threat Prevention.

Answer

A valid Threat Prevention subscription.

Answer

The policy must be installed on the management server.

Question 10

An administrator notices that Active Directory Query is failing to resolve user identities for a newly established subnet of workstations. The Security Gateway and Domain Controllers can communicate via ICMP, but queries fail. Which TWO troubleshooting steps should the administrator perform to resolve this issue? (Choose two)

Accepted Answer

Verify that TCP ports 135, 445, and ephemeral ports are allowed between the gateway and Domain Controllers.. AD Query relies on proper RPC, SMB, and WMI communication channels between the Security Gateway and Domain Controllers. Verifying firewall rules, network routing, and specific service permissions ensures that the gateway can successfully poll security logs without being blocked by intermediate network security controls.

Answer

Check that the Identity Agent executable is running on every workstation in the new subnet.

Answer

Reconfigure the Captive Portal redirection port from HTTP 80 to HTTPS 443.

Answer

Disable Kerberos ticket decryption on the gateway to force NTLM fallback authentication.

Question 11

An administrator notices that logs are truncated in SmartView. What is the most likely cause for this behavior?

Accepted Answer

The 'Maximum log size' limit is exceeded.. Truncated logs often occur when log data exceeds the maximum allowed size or when the system is misconfigured to cut off data to preserve space. Identifying the cause of truncation is vital for ensuring that full context, such as URL strings or packet payloads, is preserved for forensic investigations. Without the full log entry, critical evidence could be missing, undermining the effectiveness of security response efforts.

Answer

The log threshold setting is too low.

Answer

The SmartView index is corrupted.

Answer

The Security Gateway is running out of memory.

Question 12

Refer to the exhibit. If a user tries to access 'linkedin.com', what happens?

Accepted Answer

Access is allowed due to the URL Filtering exception.. Check Point policy evaluation follows a specific order: explicit rules, then implicit rules. Exceptions created within the URL Filtering blade take precedence over general category blocks. By defining an exception for 'linkedin.com', the administrator overrides the 'Social Networking' block, ensuring the user can access the site. This is standard behavior to prevent category-based policies from being too restrictive in a business environment.

Answer

Access is blocked because it is categorized as Social Networking.

Answer

Access is blocked because category blocks take precedence.

Answer

Access is allowed only if the user is in the Business group.

Question 13

Which THREE of the following are valid Identity Awareness 'Identity Sources' that can be used to identify users?

Accepted Answer

Active Directory Query. Check Point Identity Awareness supports multiple sources to ensure flexibility in diverse network architectures. By combining sources, administrators can create a robust identity-based security strategy. These sources allow the firewall to map IP addresses to specific users, enabling granular security policies that are context-aware and adaptive to the changing needs of the business, regardless of whether the users are on managed or unmanaged endpoints.

Answer

External Database via SQL connection

Answer

SNMP Traps from Switches

Question 14

Which TWO of the following statements accurately describe the functionality of the Identity Awareness 'Identity Collector'?

Accepted Answer

It communicates with Active Directory to retrieve identity information.. The Identity Collector is a dedicated software component that enhances performance by offloading identity acquisition from the Security Gateway. It retrieves identity data from various sources like Active Directory or Cisco ISE and pushes this information to the Gateway. This architecture is vital for large-scale environments where high traffic loads on the gateway would otherwise be negatively impacted by intensive identity polling operations and external communication overhead.

Answer

It must be installed directly on the Security Gateway.

Answer

It eliminates the need for any Identity Awareness configuration on the Gateway.

Answer

It only supports integration with Microsoft Active Directory.

Question 15

Which TWO of the following are prerequisites for configuring LDAP authentication for SmartConsole administrators?

Accepted Answer

An LDAP Account Unit object must be defined in the management database.. LDAP authentication requires the Security Management Server to communicate with the domain controller using configured server objects. Proper connectivity, specifically ensuring the server can reach the LDAP port and that the schema is correctly imported, is vital for the integration to work. This setup facilitates centralized password management, which is a key requirement for organizational security standards and regulatory compliance audits.

Answer

The Security Gateway must have Identity Awareness blade enabled.

Answer

The LDAP server must have a specific Check Point agent installed.

Answer

All administrators must have a local database account before external mapping.

Question 16

Which THREE actions occur when 'Concurrent User Sessions' is enabled for administrators?

Accepted Answer

Administrators can edit the same policy package simultaneously.. Concurrent sessions allow multiple administrators to manage the same policy simultaneously. Enabling this feature requires careful coordination and locking mechanisms to prevent overwriting changes. This is important in large organizations where multiple admins need to work in the same environment, as it balances the requirement for collaborative management with the technical necessity of maintaining database integrity and configuration consistency.

Answer

Only one administrator can connect to the management server at a time.

Answer

Changes are automatically pushed to the gateway upon saving.

Question 17

An administrator is assigned the 'Read-Only' profile. What can this administrator NOT do?

Accepted Answer

Install the security policy to the gateways.. A read-only profile is specifically designed to allow users to view the configuration without the ability to modify it. This is useful for auditing and monitoring purposes. Understanding the limitations of this role is critical for administrators to ensure they provide the right level of access while maintaining the integrity of the security policy, as any unauthorized modification could result in serious security vulnerabilities.

Answer

View the current security policy rules.

Answer

Generate reports via SmartConsole.

Answer

Log in to the SmartConsole.

Question 18

Which THREE factors are required to successfully integrate SmartConsole with an external TACACS+ server for administrative authentication?

Accepted Answer

Valid shared secret between the gateway and server. Integrating external authentication is a multi-step process involving the management server configuration, the network connectivity, and the TACACS+ server policy. Ensuring these three areas are aligned is critical because failures in any one component will lead to authentication timeout or rejection, potentially locking out admins from the management interface during critical operational periods.

Answer

Configured user groups in the local database

Answer

Disabled Multi-Factor Authentication

Question 19

An administrator wants to audit all changes made to the security policy by other administrators. Which tool should they use?

Accepted Answer

The Audit Log in SmartConsole. The Audit Log within SmartConsole is the primary tool for tracking all administrative activity, including who made a change, when it was made, and what the change involved. This is essential for compliance, troubleshooting, and forensics, allowing administrators to maintain a clear history of modifications and ensuring that any unauthorized or accidental changes can be quickly identified and reversed.

Answer

SmartView Monitor

Answer

SmartEvent

Answer

The 'fw log' CLI command

Question 20

Refer to the exhibit. An administrator is configuring RADIUS authentication for Identity Awareness. What is the cause of this error log?

Accepted Answer

The RADIUS server and gateway have mismatched encryption keys.. The 'shared secret mismatch' error explicitly indicates that the RADIUS client (the Security Gateway) and the RADIUS server are using different keys to encrypt their communications. This is a common configuration error in AAA setups. Both the gateway and the server must have an identical, correctly typed shared secret string, or the authentication handshake will be rejected by the server for security reasons.

Answer

The RADIUS server is down.

Answer

The firewall policy is blocking RADIUS traffic.

Answer

The user password is incorrect.
