156-215.81.20 Practice Test 16 — 15 Questions

Question 1

When using LDAP as an external authentication provider for administrators, why must the 'Search Base' be configured correctly?

Accepted Answer

To specify the location in the directory to begin the user search. The Search Base defines the starting point in the LDAP directory tree for user queries. If misconfigured, the management server will fail to find the user objects, resulting in failed authentication. Proper configuration of the search base is essential for ensuring that the firewall can successfully query the directory to verify administrative credentials during the login sequence.

Answer

To define the encryption level of the password hash

Answer

To enable write-access for the management server

Answer

To bypass the need for an LDAP service account

Question 2

What is the primary function of the 'Identity Collector' in a distributed Identity Awareness environment?

Accepted Answer

Offloading identity collection from the Gateway.. The Identity Collector is a dedicated software component that offloads the task of querying directory services (like Active Directory) from the Security Gateway. By centralizing the collection of identity events, it reduces the load on the gateway's CPU and allows for the integration of multiple identity sources, such as Cisco ISE or Windows Event Logs, into a single, unified feed for the security gateways.

Answer

Encrypting all user traffic.

Answer

Providing endpoint antivirus protection.

Answer

Enforcing access policies on the user.

Question 3

Where do you configure 'Automatic NAT' for a specific network host object in SmartConsole?

Accepted Answer

Within the NAT tab of the Network Object properties.. Automatic NAT is configured directly within the Network Object properties. By navigating to the NAT tab of an object (such as a Host or Network), an administrator can enable 'Add automatic address translation rules'. This simplifies management by automatically creating the required NAT rules in the background, ensuring consistency across the security policy without requiring manual rule creation for each object.

Answer

In the Security Policy tab under the NAT section.

Answer

In the Global Properties under NAT settings.

Answer

Using the 'fw nat' command in the CLI.

Question 4

Which phase of the IKE negotiation is responsible for authenticating the peers and establishing a secure channel for subsequent management traffic?

Accepted Answer

IKE Phase 1 (Main/Aggressive Mode). IKE Phase 1 establishes the bidirectional secure tunnel, known as the ISAKMP SA, which protects subsequent IKE negotiations. This phase is crucial for ensuring that identities are verified before exchanging sensitive keying material. Without successful Phase 1, no Phase 2 SAs can be established to protect user data, making it the foundational security handshake in any site-to-site VPN implementation on Check Point gateways.

Answer

IKE Phase 2 (Quick Mode)

Answer

Diffie-Hellman Group negotiation

Answer

PFS (Perfect Forward Secrecy) phase

Question 5

Which TWO of the following are consequences of using 'Hide NAT' incorrectly in a network environment?

Accepted Answer

Port exhaustion due to high concurrent connections.. Incorrect Hide NAT usage can lead to port exhaustion, where too many connections share a single IP and run out of available source ports. Furthermore, it can cause return traffic routing failures if the upstream device does not know how to handle the translated source IP. Both issues result in significant connectivity outages for the internal services that rely on these NAT mappings.

Answer

Increased security due to internal IP obfuscation.

Answer

Automatic encryption of all internal traffic.

Answer

Improved performance for all internal applications.

Question 6

Which blade must be active to perform HTTPS Inspection on traffic?

Accepted Answer

HTTPS Inspection. HTTPS Inspection is a prerequisite for several other blades, including Application Control, URL Filtering, and Threat Prevention. It is managed via a dedicated policy area in the SmartConsole. The inspection engine decrypts SSL/TLS traffic, inspects the plaintext, and then re-encrypts it, allowing the security blades to see the content that would otherwise be hidden from the gateway, which is essential for modern security.

Answer

Threat Emulation

Answer

Application Control

Answer

Identity Awareness

Question 7

What is the difference between 'Main Mode' and 'Aggressive Mode' in IKE Phase 1?

Accepted Answer

Main Mode protects peer identity. Main Mode provides identity protection by encrypting the exchange and hiding the gateway's identity until after the tunnel is established. Aggressive Mode is faster but sends the peer's ID in cleartext, which is less secure but useful in scenarios where the dynamic IP of a remote client makes Main Mode difficult to negotiate. Choosing between them involves balancing security posture against connection speed and network compatibility.

Answer

Main Mode is faster than Aggressive

Answer

Aggressive Mode is more secure than Main

Answer

Aggressive Mode supports more DH groups

Question 8

Which object property must be enabled on a gateway for it to support NAT?

Accepted Answer

NAT. The 'NAT' blade must be enabled within the gateway's general properties. Without this feature enabled, the gateway will not process NAT rules defined in the policy. This is a foundational step in Check Point administration, as NAT configurations rely entirely on the NAT blade being active to translate internal addresses to external ones for internet access or vice-versa.

Answer

Threat Prevention

Answer

IPSec VPN

Answer

Identity Awareness

Question 9

An administrator wants to ensure that logs are indexed properly for quick searching in SmartView. Which process is responsible for this indexing?

Accepted Answer

log_indexer. The log indexing process is critical for search performance. Understanding that the Log Indexer daemon performs this task allows administrators to troubleshoot why certain logs might be missing from search results. If the indexer is failing, searching becomes extremely slow or impossible, even if the logs are physically present on the server's disk.

Answer

fwd

Answer

cpd

Answer

smartview_server

Question 10

Refer to the exhibit. An administrator notices that traffic from Internal_Net to Server_Farm is being translated by Rule 1 instead of Rule 2. What is the most likely cause?

Accepted Answer

Rule 1 is processed before Rule 2 due to rule order.. NAT rules are processed in order from top to bottom. If Rule 1 matches the traffic first, the gateway applies that rule and stops processing subsequent rules. In this case, Rule 1 is too broad ('Dst: Any'), causing it to 'shadow' or override Rule 2. Administrators must order rules from most specific to least specific to ensure the correct NAT translation is applied to targeted traffic flows.

Answer

Rule 2 is disabled by default.

Answer

The gateway requires a reboot to update the NAT rule base.

Answer

The object 'Server_Farm' is not defined correctly.

Question 11

An administrator is troubleshooting an issue where users are identified as 'Unknown' despite having Identity Awareness enabled. What is the first logical step to investigate?

Accepted Answer

Check 'pdp monitor' output.. The most effective first step is to check if the gateway is correctly receiving identity information from the sources. Using the command 'pdp monitor' allows the administrator to see the current status of all configured identity sources. If the source shows as 'Disconnected' or 'Failed', the problem lies in the connectivity or credentials used for the identity source, rather than a policy-level filtering issue.

Answer

Restart the security gateway.

Answer

Review the Access Control policy.

Answer

Reinstall the Identity Agent.

Question 12

Which object type should an administrator use to block access to a wide range of websites deemed inappropriate, such as adult content?

Accepted Answer

A URL Filtering category.. URL Filtering categories are the most efficient way to block vast numbers of sites based on their content type. Instead of manually inputting thousands of individual URLs, administrators use these pre-defined categories provided by Check Point. This approach is highly scalable and ensures that new sites added to these categories are automatically blocked as the cloud-based database updates, keeping the policy effective without constant manual intervention by the security team.

Answer

An Application object.

Answer

A Service object.

Answer

A Host object.

Question 13

What is the primary benefit of the 'ThreatCloud' service for URL Filtering?

Accepted Answer

It provides real-time updates and global intelligence on URLs.. ThreatCloud provides real-time, global threat intelligence and URL categorization. By querying this cloud service, the gateway receives immediate updates on newly registered malicious domains or updated site categories. This is vital because the landscape of malicious websites changes daily; local database snapshots are insufficient, and cloud-based intelligence ensures the gateway stays ahead of emerging threats by leveraging data collected from millions of sensors worldwide in a collaborative security model.

Answer

It replaces the need for local gateway policy rules.

Answer

It forces all traffic to be sent to a Check Point data center for processing.

Answer

It automatically decrypts all HTTPS traffic for the gateway.

Question 14

Refer to the exhibit. An administrator reports they can see all objects but cannot push policies. Reviewing the configuration, what is the most likely cause of this restriction?

Accepted Answer

The assigned Permission Profile lacks 'Install Policy' rights. The exhibit shows the admin configuration file where permissions are mapped. In Check Point, read-write access at the object level does not automatically grant the 'Policy Installation' privilege. This distinction is vital for maintaining segregation of duties, where one admin might manage objects while another is explicitly authorized to perform the risk-heavy task of pushing security policies to gateways.

Answer

The administrator's database is corrupted

Answer

The administrator is logged into the wrong domain

Answer

The gateway is currently in a cluster state

Question 15

Why might you use a 'Hide NAT' rule with a specific IP pool instead of a single interface IP?

Accepted Answer

To increase the total number of concurrent connections.. Using a pool of public IP addresses for Hide NAT allows for scaling across many internal hosts. A single IP address has a limit on the number of concurrent connections (due to port exhaustion). By using a pool, the gateway can distribute outgoing sessions across multiple public IPs, significantly increasing the total number of simultaneous connections that can be supported.

Answer

To hide the gateway's actual interface address.

Answer

To allow external hosts to initiate connections.

Answer

To improve internal routing performance.
