156-315.81.20 Practice Exam 2 — 20 Questions

Question 1

Refer to the exhibit. An administrator notices that the cluster state is Active/Standby, but the sync status shows 'Problem'. What is the most likely consequence for the network traffic?

Accepted Answer

Existing connections will be dropped if the active member fails, as the standby unit lacks state information.. When the sync status indicates a problem, the cluster members cannot share connection state information. Although traffic still flows through the active member, any failover event will cause all existing connections to drop because the standby member lacks the current connection table. This state renders the HA solution ineffective for session persistence, making immediate investigation of the synchronization interface or connectivity between members mandatory for maintaining service continuity.

Answer

The active member will stop passing traffic until the synchronization issue is resolved by the administrator.

Answer

The cluster will enter a 'Split Brain' condition, causing duplicate IP address conflicts on the network.

Answer

The standby member will automatically promote itself to active status to force a resynchronization attempt.

Question 2

Which TWO authentication methods are natively supported by Check Point Identity Awareness for acquiring user identities without requiring a client-side agent installation? (Choose TWO)

Accepted Answer

Active Directory Query (AD Query). Active Directory Query and Captive Portal allow the Security Gateway to identify users transparently or interactively without deploying software to endpoints. AD Query reads domain controller events, while Captive Portal prompts users via a browser redirect, making both methods ideal for unmanaged devices or environments where endpoint agent deployment is restricted.

Answer

Check Point Endpoint Identity Agent

Answer

Terminal Server Identity Agent

Answer

Browser-Based Identity Agent

Question 3

When configuring Threat Prevention, what is the significance of the 'Hold' vs. 'Background' emulation mode?

Accepted Answer

'Hold' mode prevents the file from reaching the user until the emulation is finished.. The emulation mode determines the user experience and security trade-off. 'Hold' mode blocks file access until the emulation is complete, ensuring maximum security but adding latency. 'Background' mode allows the file to be downloaded immediately while emulation runs in parallel. If the file is later found malicious, the security gateway can then block it, but the user may have already received the file, presenting a risk of temporary exposure.

Answer

'Hold' mode is only available for files larger than 10MB.

Answer

'Background' mode is the default and most secure setting.

Answer

'Background' mode is necessary for all HTTPS traffic.

Question 4

What is the primary benefit of using CPUSE (Check Point Upgrade Service Engine) for gateway upgrades compared to manual 'upgrade_export' and re-installation methods?

Accepted Answer

It automates the installation process, reduces manual effort, and performs pre-upgrade validation checks.. CPUSE is designed to automate the download, installation, and verification of software packages, significantly reducing the potential for human error. By handling dependencies, pre-flight checks, and package management in a unified interface, it streamlines the maintenance process, ensures that the gateway environment remains consistent, and allows for easier rollback options if an upgrade encounter unexpected issues during the deployment.

Answer

It allows for the downgrade of the operating system version to an older release.

Answer

It automatically performs a full system backup before starting the upgrade process.

Answer

It removes the need to maintain an active internet connection to the Check Point User Center.

Question 5

Which feature must be enabled on the network interface to allow SecureXL to distribute the processing load across multiple CPU cores effectively?

Accepted Answer

Multi-Queue. Multi-Queue is the essential technology that allows the network interface card (NIC) to spread incoming traffic across multiple receive queues. Without Multi-Queue, all traffic would arrive at a single CPU core, negating the benefits of CoreXL. Enabling Multi-Queue ensures that the gateway can handle higher concurrent traffic loads, as each queue can be assigned to a different processing core, maximizing the total throughput capacity of the system.

Answer

VLAN Tagging

Answer

Dynamic Routing

Answer

Jumbo Frames

Question 6

Which core software blade must be enabled on a Check Point Security Gateway to allow the creation of access control rules based on Active Directory user groups and computer objects?

Accepted Answer

Identity Awareness. Identity Awareness is the foundational Check Point software blade responsible for identifying network users and computer objects across various access methods. Enabling this blade enables administrators to write granular security policies incorporating directory attributes, ensuring robust access control aligned with corporate identity management structures.

Answer

URL Filtering

Answer

Threat Emulation

Answer

Application Control

Question 7

What is the primary function of the 'VPN Domain' in a Check Point VPN community?

Accepted Answer

It defines the range of IP addresses for which the gateway will encrypt traffic.. The VPN Domain defines the specific network objects that are 'interesting' to the VPN. When traffic hits the gateway, it compares the destination IP against the VPN Domain. If it matches, the gateway initiates the VPN tunnel. This effectively tells the firewall which traffic is internal and requires encryption, and which traffic should be handled normally via standard routing or NAT outside the VPN context.

Answer

It determines which authentication method the remote user must use.

Answer

It manages the distribution of certificates to remote gateways.

Answer

It controls the encryption algorithms used for the VPN tunnel.

Question 8

When configuring a VPN with multiple encryption domains, what is the most effective way to ensure traffic is correctly routed through the tunnel without complex policy rules?

Accepted Answer

Implementing VTI and using the routing table.. Using Route-Based VPNs with Tunnel Interfaces (VTI) allows the routing table to make the decision rather than the policy. This simplifies management, as adding a new network only requires updating the routing table rather than modifying complex policy rules or VPN domain groups. This is the industry-standard approach for large, scalable networks needing robust traffic engineering.

Answer

Defining one massive group object for all domains.

Answer

Using policy-based VPNs with extensive exclusion rules.

Answer

Enabling manual tunnel establishment at the gateway.

Question 9

Which TWO of the following are primary functions of the Threat Extraction blade in Check Point SandBlast? (Choose two)

Accepted Answer

Delivering a clean, flattened PDF version of an original document to the user immediately.. Threat Extraction provides immediate protection by proactively removing potentially malicious content from files, rather than waiting for sandbox analysis to complete. By delivering a sanitized version of the document to the user, it maintains workflow productivity. This function is vital for organizations that cannot afford the latency associated with full emulation, ensuring that business-critical documents remain accessible even if they contain active, suspicious content.

Answer

Updating the local ThreatCloud database with new malware signatures detected.

Answer

Performing full behavioral analysis on executable files to determine malicious intent.

Answer

Blocking encrypted archives that cannot be scanned for malware.

Question 10

Refer to the exhibit. An administrator is troubleshooting a site-to-site VPN tunnel. What is the most effective next step to resolve the 'No proposal found' error?

Accepted Answer

Update the VPN Community to match the peer's IKE parameters.. The 'No proposal found' error signifies that the Security Gateway does not recognize or accept the parameters offered by the remote peer. This is a common issue in large-scale VPN deployments where policy mismatches occur due to manual configuration errors. Synchronizing the IKE Phase 1 settings, specifically ensuring the Diffie-Hellman group and encryption standards align exactly, resolves the incompatibility and allows the tunnel negotiation to proceed.

Answer

Re-generate the internal CA certificate on the gateway.

Answer

Increase the IKE lifetime settings in the VPN Community.

Answer

Disable NAT-T on the Security Gateway interface.

Question 11

Which TWO requirements must be met before a Security Gateway can be successfully provisioned using the Zero Touch Provisioning (ZTP) service?

Accepted Answer

The appliance must have internet access to reach the Check Point Cloud.. Zero Touch Provisioning relies on the appliance being able to reach the Check Point Cloud to fetch its configuration. This requires the device to have a serial number registered in the Zero Touch portal and a valid path to the internet, usually via DHCP on the designated management or first interface.

Answer

The administrator must manually run the 'cpconfig' command on the CLI first.

Answer

A console cable must be connected to the appliance during the boot sequence.

Answer

The Security Management Server must be in the same Layer 2 network segment.

Question 12

What is the primary function of the 'fwaccel' module in the context of Check Point performance tuning?

Accepted Answer

It offloads packet inspection to the fast path.. The 'fwaccel' module is the heart of SecureXL, responsible for offloading packet processing from the CPU to the hardware acceleration path. By reducing the number of packets that require full inspection, it significantly increases the gateway's throughput. Understanding the role of this module is fundamental for performance tuning, as it allows administrators to recognize the boundary between hardware-accelerated traffic and the traffic that requires full kernel inspection for security validation.

Answer

It manages the routing table entries.

Answer

It handles user authentication for the gateway.

Answer

It enables logging for all traffic.

Question 13

When deploying a new Security Gateway, what is the role of the 'First Time Wizard'?

Accepted Answer

It configures the base network and administrative settings.. The First Time Wizard is a critical tool for initializing a gateway's base configuration, including network interfaces, DNS, NTP, and basic administrative access. It ensures that the gateway is correctly identified and reachable within the network before being connected to the Security Management Server. Properly configuring these parameters through the wizard prevents common connectivity issues during the initial registration of the gateway into the Check Point environment.

Answer

It automatically installs the latest jumbo hotfix.

Answer

It pushes the security policy from the management server.

Answer

It automatically creates the SIC trust with the SMS.

Question 14

Refer to the exhibit. An administrator sees this CPU distribution on a gateway. What is the most appropriate action?

Accepted Answer

Review security policy for non-acceleratable features. This CPU breakdown shows high kernel utilization, suggesting the firewall engine is overburdened, while SecureXL is underutilized. This indicates that traffic is not being successfully offloaded. The administrator should investigate policies or features preventing acceleration, such as complex rules or inspection settings. Addressing this allows the gateway to shift the load from the kernel to the faster SecureXL path, significantly improving throughput and responsiveness.

Answer

Increase the number of CoreXL instances

Answer

Lower the MTU size on the interfaces

Answer

Reinstall the gateway software

Question 15

A security administrator needs to ensure that all encrypted traffic is inspected by the Threat Prevention blades. What is the mandatory requirement for this?

Accepted Answer

Configure the HTTPS Inspection policy and install the CA certificate on all client machines.. HTTPS Inspection is essential because many threats are delivered over encrypted channels to bypass inspection. By performing HTTPS Inspection, the gateway decrypts the traffic, inspects the payload using Threat Prevention blades, and re-encrypts it before sending it to the destination. This provides full visibility into the traffic, ensuring that malicious content hidden within encrypted payloads is effectively detected and blocked before reaching the internal network or the user's endpoint.

Answer

Enable SSL Inspection in the Threat Prevention policy.

Answer

Upgrade to the latest JHF (Jumbo Hotfix) on the Management Server only.

Answer

Enable the 'Deep Packet Inspection' blade globally on all interfaces.

Question 16

When deploying a Security Gateway in a public cloud environment like AWS or Azure, which method is typically used to handle the initial Gaia configuration?

Accepted Answer

Cloud-Init or CloudConfig scripts provided during instance creation.. Cloud deployments often use specialized templates or scripts to automate the initial setup, ensuring that the gateway is correctly integrated with the cloud provider's networking and identity services. This differs from physical appliance deployments where manual console access or ZTP is more common.

Answer

Physical console redirection via a serial-over-LAN connection.

Answer

Using a USB bootable drive with a 'Blink' image pre-installed.

Answer

Connecting to the default IP 192.168.1.1 via a local crossover cable.

Question 17

Refer to the exhibit. Rule 5 allows the group 'Admins'. Why is the user 'admin' being blocked?

Accepted Answer

The rule has additional constraints (e.g., source/destination/time) not met.. The user is correctly associated with the 'Admins' group. If a rule specifically allowing this group is blocking the traffic, it is highly likely that the rule contains additional restrictions, such as time-based limitations, specific service restrictions, or the rule is being shadowed by a higher-priority block rule. Alternatively, the user might be mapped to the group, but the rule requires an additional factor like a specific machine or device.

Answer

The user is not authenticated.

Answer

The PDP table is corrupt.

Answer

The group 'Admins' is not synced to the gateway.

Question 18

When should an administrator consider changing the 'CoreXL instance' count?

Accepted Answer

When the CPU usage indicates an imbalance or capacity constraint. The CoreXL instance count should be adjusted when there is a significant change in traffic volume or available CPU cores. If CPU utilization is uneven or consistently high, adding instances can help distribute the load, provided there are sufficient physical cores available. This tuning ensures that the gateway can handle peak traffic without dropping packets, maintaining the integrity and availability of the network inspection services.

Answer

Only when installing a new software version

Answer

Whenever a new security blade is enabled

Answer

When the gateway is in Standby mode in a cluster

Question 19

In ClusterXL High Availability mode, how many cluster members can be active for a specific virtual IP at any given time?

Accepted Answer

Only one member is active at a time.. High Availability mode is designed for redundancy, not load distribution. Consequently, only one member acts as the Active gateway, while the other remains in a Standby state. This ensures a clear ownership of the virtual IP and simplifies troubleshooting, as traffic flow is deterministic. If the active member fails, the standby member promotes itself to active to maintain service availability.

Answer

All members are active simultaneously for redundancy.

Answer

Up to four members can be active concurrently.

Answer

The number of active members is equal to the number of nodes in the cluster.

Question 20

An administrator notices that the Threat Extraction blade is converting incoming Microsoft Word documents into static PDF files, but users complain that embedded dynamic macros are completely missing from the converted documents. What is the cause of this behavior?

Accepted Answer

Threat Extraction permanently strips all active content, including macros, when rebuilding documents into safe formats.. Threat Extraction operates by removing active content such as macros, scripts, and embedded objects instantly to deliver a clean file while the full inspection happens. When converting files, active content elements are stripped out rather than preserved. This proactive approach prevents zero-day exploits safely without delaying initial user access, making it essential to understand for user expectation management.

Answer

The Threat Emulation blade failed to sandbox the Word document, causing the macro engine to crash during conversion.

Answer

The Security Gateway lacks sufficient memory resources to process complex Visual Basic for Applications scripts during extraction.

Answer

Anti-Bot policy rules supersede Threat Prevention settings, causing active document elements to be blocked at the firewall layer.
