156-315.81.20 Practice Test 4 — 10 Questions

Question 1

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 2

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 3

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 4

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 5

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 6

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 7

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 8

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 9

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 10

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.
