156-315.81.20 Quick Quiz — 10 Questions

Question 1

You are upgrading a Security Gateway from R80.40 to R81.20 using the CPUSE 'In-Place Upgrade' method. After the upgrade, you notice the gateway is not communicating with the Management Server. Which file should you check first to identify potential SIC-related errors during the boot process?

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

Accepted Answer

$FWDIR/log/cpd.elg. Checking the cpd.elg file is critical because it captures the Check Point Daemon logs, which document the secure communication initialization process. During an upgrade, SIC certificates or trust relationships can occasionally fail to re-initialize due to connectivity issues or synchronization mismatches. By examining these logs, an administrator can quickly pinpoint whether the issue stems from a certificate expiration, an incorrect IP address resolution, or a failure in the initial handshake process between the gateway and management.

Answer

$FWDIR/log/fw.log

Answer

/var/log/messages

Answer

$FWDIR/log/fwm.log

Question 2

Which THREE factors can cause a ClusterXL member to transition to a 'Down' state?

Accepted Answer

The Security Gateway process (fwd) is not responding on the local member.. A member enters the 'Down' state when critical processes stop responding or connectivity is lost. Monitoring these factors is essential for HA stability. Failures in critical processes like fwd or cphad, or persistent loss of connectivity on heart-beat interfaces, directly trigger state transitions. Administrators must monitor these components carefully, as a 'Down' state triggers an automatic failover to the secondary gateway, affecting production traffic patterns during the transition period.

Answer

A temporary spike in CPU utilization exceeding 90% for two seconds.

Answer

An administrator manually initiates a policy install on a peer member.

Question 3

Which TWO of the following are benefits of using the Threat Prevention 'Recommended' profile over a custom profile?

Accepted Answer

It automatically includes the latest security best practices from Check Point.. The 'Recommended' profile is a pre-configured best-practice policy designed by Check Point security researchers. It automatically incorporates the most effective settings, balance of blades, and confidence levels. Using this profile ensures that the security posture is aligned with industry-standard best practices, reducing administrative overhead and preventing gaps in protection that often occur due to misconfigurations or the omission of critical protections during custom policy creation.

Answer

It disables all non-essential features to maximize network throughput.

Answer

It guarantees zero false positives in every network environment.

Answer

It forces all traffic to be inspected by every blade regardless of protocol.

Question 4

A Check Point administrator is configuring a Site-to-Site VPN between a Security Gateway and a third-party device using IKEv2. The third-party device requires a specific non-standard IKEv2 proposal. Where should the administrator define this custom proposal in SmartConsole?

Accepted Answer

Under the Gateway object > IPsec VPN > Advanced > IKEv2 Proposals.. Custom IKEv2 proposals are defined within the VPN Advanced settings of the Gateway object. While standard proposals are pre-defined, interoperability with third-party vendors often necessitates manual negotiation settings. Defining these correctly is critical for successful Phase 1 establishment, as mismatches in encryption, integrity, or Diffie-Hellman groups will result in IKE negotiation failures, preventing the tunnel from initiating securely between the disparate security appliances.

Answer

In the Global Properties under VPN Advanced settings.

Answer

Within the VPN Community object properties.

Answer

In the Policy tab under the VPN Rule properties.

Question 5

Which command is used to manually verify the synchronization status of the kernel tables between ClusterXL members?

Accepted Answer

cphaprob syncstat. The 'cphaprob' command is the primary utility for troubleshooting and verifying ClusterXL status. Specifically, 'cphaprob syncstat' provides detailed information regarding the synchronization of kernel tables. Monitoring this output is critical for identifying synchronization latency, missed updates, or connection table mismatches that could lead to dropped packets or session resets after a failover event, ensuring that both members maintain consistent state information.

Answer

cphaprob stat

Answer

fw ctl pstat

Answer

cphaprob list

Question 6

Refer to the exhibit. What is the impact of having templates disabled on this gateway?

Accepted Answer

The firewall will process all packets in the connection. Templates are the core mechanism for SecureXL acceleration. When disabled, the gateway cannot create the fastpath entries needed for sustained connections. Consequently, every packet must be processed by the Firewall kernel, leading to significantly higher CPU consumption and lower throughput. This is a critical configuration issue because it renders the acceleration layer ineffective, forcing the system to perform full inspection on every packet, even for established sessions.

Answer

Only the first packet of each connection is processed by the firewall

Answer

The gateway will automatically enable templates after 60 seconds

Answer

This configuration is required for HTTPS Inspection

Question 7

An administrator is troubleshooting an Identity Awareness deployment where AD Query fails to resolve user identities for workstations located in a newly added branch office subnet. The Security Gateway can successfully ping the Domain Controllers in the branch office. What is the most likely cause of this communication failure?

Accepted Answer

Necessary ports such as RPC (135) and SMB (445) are blocked between the Security Gateway and the Domain Controllers.. AD Query relies on specific remote procedure call mechanisms and Windows Management Instrumentation protocols to read Security Event logs from Domain Controllers. If required ports like RPC Endpoint Mapper (135), SMB (445), or dynamic RPC ports are blocked by intermediate firewalls or host firewalls, the gateway cannot poll logs, resulting in complete identity resolution failure.

Answer

The Security Gateway lacks the necessary routing table entries to reach the branch office local subnet.

Answer

The branch office workstations have not installed the Check Point Identity Agent software.

Answer

The Captive Portal Web API service on the Security Gateway has been stopped by the administrator.

Question 8

Refer to the exhibit. What is the most immediate risk to this cluster configuration?

Accepted Answer

Existing connections will not survive a failover event.. The synchronization interface (eth1) is in a 'Down' state while the cluster is in an active/standby configuration. This means the active member cannot replicate state information to the standby member. If the active member fails, all current connections will be dropped because the standby member has no knowledge of existing sessions. This risk makes the cluster functionally equivalent to a simple failover pair without state persistence.

Answer

The firewall will stop passing traffic on the External interface.

Answer

The standby member will attempt to go Active, resulting in IP conflicts.

Answer

The cluster will automatically disable the External interface to prevent data loss.

Question 9

An administrator needs to implement Identity Awareness in a large environment with multiple Active Directory domains. Which method ensures the most efficient identity retrieval without requiring client-side agent installations on every workstation?

Accepted Answer

Active Directory Query (AD Query). Active Directory Query (AD Query) is the optimal choice here as it leverages WMI/RPC to monitor domain controller security logs for Kerberos/NTLM authentication events. This agentless approach provides real-time identity mapping across complex domain topologies without the administrative overhead of deploying and maintaining Identity Agents on thousands of endpoints, ensuring seamless scalability and minimal impact on user systems.

Answer

Identity Agent

Answer

Browser-Based Authentication

Answer

Remote Access VPN

Question 10

An administrator observes that the 'fw multik' process is consuming significantly more CPU than other processes. What is the most likely cause, and which feature configuration should be checked?

Accepted Answer

Check CoreXL instance count and interface affinity. When the 'fw multik' process consumes excessive CPU, it often indicates an imbalance in CoreXL instance distribution. This occurs when traffic is pinned to a single core or when high-volume traffic matches a rule that cannot be distributed effectively. Tuning core affinity and ensuring that the traffic is evenly distributed across all available CoreXL instances is essential to restore balanced processing and prevent specific core exhaustion.

Answer

Check SecureXL global status

Answer

Increase the amount of RAM on the gateway

Answer

Disable the Application Control blade
