156-315.81.20 Practice Test 11 — 15 Questions

Question 1

A Check Point Security Gateway uses Identity Awareness with AD Query. An administrator notices that user identities are not being recognized in firewall rules that reference Active Directory groups. The gateway can identify individual users, but group-based rules do not match. What is the most likely cause?

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

Accepted Answer

The gateway is not configured to synchronize user groups from Active Directory, or the groups are not included in the Identity Awareness configuration.. Identity Awareness must be configured to synchronize group information from Active Directory for group-based rules to work. If only user identification is enabled, the gateway lacks the group membership data needed to evaluate rules referencing AD groups. Ensuring group synchronization is the key step to resolve the issue.

Answer

The Security Gateway's Identity Awareness blade is not licensed for group-based identification.

Answer

The AD Query account lacks permissions to read group membership information from Active Directory.

Answer

The firewall rules are using the wrong source object type; they should reference users instead of groups.

Question 2

An administrator is deploying a new R81.20 Security Gateway cluster. The cluster will use ClusterXL in High Availability mode. The administrator wants to ensure that the cluster members can communicate with each other for synchronization and failover. Which network configuration is required for the synchronization interface?

Accepted Answer

The synchronization interface must be configured with a unique IP address on each cluster member and be on the same dedicated subnet.. ClusterXL synchronization requires each cluster member to have a dedicated interface with a unique IP address on the same subnet. This dedicated subnet ensures that synchronization and heartbeat traffic is isolated from other network traffic, providing reliable and secure communication between cluster members. Other configurations either violate IP uniqueness or do not provide the necessary isolation.

Answer

The synchronization interface must be configured as a VLAN trunk to carry both synchronization and management traffic.

Answer

The synchronization interface must be on the same subnet as the management interface.

Answer

The synchronization interface must use the same IP address on all cluster members to simplify routing.

Question 3

A Check Point administrator is troubleshooting a Site-to-Site VPN where the tunnel is up, but traffic is not passing. The administrator runs 'vpn tu tlist' and sees the tunnel is established. However, 'fw monitor' shows packets being dropped with the error 'Encryption failure: no SA'. What is the most likely cause?

Accepted Answer

The encryption domain of the local gateway does not include the source or destination network of the dropped packets.. The error 'Encryption failure: no SA' occurs when a packet matches a VPN rule but the gateway cannot find an existing SA for that traffic. This usually happens when the packet's source or destination is not included in the VPN encryption domain, so the gateway cannot map it to the established tunnel. The administrator should check the VPN Domain settings on both gateways to ensure they include all relevant networks.

Answer

The Security Gateway's routing table is missing a route to the remote network.

Answer

The pre-shared key is incorrect.

Answer

The VPN community is not configured to allow the specific traffic.

Question 4

A Check Point administrator is deploying a ClusterXL High Availability cluster with two members. The administrator wants to ensure that the cluster can properly synchronize connection tables and maintain state during failover. Which two conditions must be met for successful synchronization? (Choose two.)

Accepted Answer

Both cluster members must run the same Check Point software version and patch level.. Successful ClusterXL synchronization requires that both members run the same software version and patch level, and that a synchronization network is properly configured and reachable. Version consistency ensures that Full Sync can transfer kernel tables without compatibility issues. A dedicated sync network provides the communication path for state updates. These two conditions are essential for maintaining synchronized connection tables and ensuring seamless failover.

Answer

The cluster members must have the same number of network interfaces.

Answer

The cluster members must be configured with the same cluster ID and cluster name.

Answer

Both cluster members must have identical hardware configurations.

Question 5

A security administrator is configuring a ClusterXL High Availability cluster. The administrator wants to verify that the cluster is using the correct synchronization interface and that the synchronization status is healthy. Which command should be used to display the synchronization status of the cluster members?

Accepted Answer

cphaprob syncstat. The `cphaprob syncstat` command is designed to show synchronization statistics, including the sync interface and any errors. It allows administrators to confirm that the synchronization network is functioning and that the standby member is receiving updates. Other commands provide interface or general HA status but lack the specific sync details needed for this verification.

Answer

fw ctl pstat

Answer

cphaprob -a if

Answer

cpstat ha

Question 6

An administrator is preparing to upgrade a Security Gateway from R80.40 to R81.20 using CPUSE. Before starting the upgrade, the administrator wants to ensure that the gateway meets all prerequisites. Which two actions should the administrator perform? (Choose two.)

Accepted Answer

Run the Pre-Upgrade Verifier to check for potential issues.. Before upgrading, it is essential to verify sufficient disk space and run the Pre-Upgrade Verifier. These steps help identify and mitigate potential issues, ensuring a successful upgrade. Disabling blades, uninstalling hotfixes, or changing IP addresses are not required and could introduce unnecessary risks or complications.

Answer

Disable all blade protections to prevent interference with the upgrade.

Answer

Manually uninstall all hotfixes to ensure a clean upgrade.

Answer

Change the gateway's IP address to avoid conflicts during the upgrade.

Question 7

A security administrator notices that a user downloaded a file that was flagged as malicious by Threat Emulation, but the file was not blocked. The Threat Prevention policy shows that the Threat Emulation blade is set to 'Detect' mode for that user group. What is the most likely reason the file was not blocked?

Accepted Answer

The Threat Emulation blade is configured to only detect and not block malicious files.. When Threat Emulation is set to Detect mode, it logs malicious files but does not block them. To block, the action must be Prevent. The scenario shows the file was flagged, so the blade is active, but the action is set to Detect, resulting in no block.

Answer

The user has administrator privileges, which bypass Threat Emulation blocking.

Answer

The file was not actually malicious; the detection was a false positive.

Answer

The Threat Emulation blade is not enabled for the user's group.

Question 8

An administrator is configuring a VPN community in a Check Point R81 environment to support multiple remote access clients using Office Mode. The administrator needs to ensure that Office Mode IP addresses are assigned correctly. Which two statements about Office Mode are true? (Choose two.)

Accepted Answer

Office Mode assigns an IP address to the remote client from a predefined pool, allowing the client to access internal resources as if it were on the local network.. Office Mode assigns a virtual IP from a pool, DHCP, or manual configuration, allowing remote clients to access internal resources. It does not require a public IP, is not for Site-to-Site VPNs, and does not automatically encrypt all traffic. The two correct statements are that it assigns an IP from a predefined pool and that allocation can be from DHCP, manual pool, or gateway-defined pool.

Answer

Office Mode is only supported for Site-to-Site VPNs and not for Remote Access VPNs.

Answer

Office Mode automatically encrypts all traffic from the client, including traffic destined for the Internet, without any configuration.

Answer

Office Mode requires the remote client to have a publicly routable IP address to establish the VPN tunnel.

Question 9

A security administrator has a two-member ClusterXL High Availability cluster running R81.20. After a power failure at the primary site, the secondary member becomes active. When the primary member reboots, the administrator wants it to automatically resume the active role. Which ClusterXL setting should be configured to achieve this behavior?

Accepted Answer

Set the cluster member priority to a higher value on the primary member and verify that the cluster is in High Availability mode.. In ClusterXL High Availability mode, the active member is elected based on priority. The member with the highest priority becomes active when it is available. Therefore, setting a higher priority on the primary member ensures it reclaims the active role after recovery. Load Sharing and VRRP are not appropriate here because they change the cluster mode or protocol and do not provide the desired automatic active-role restoration.

Answer

Enable Load Sharing mode and assign the primary member a higher priority.

Answer

Set the cluster to use VRRP and assign the primary member a higher priority.

Answer

Configure the primary member as a standby member and the secondary member as active, then rely on failover.

Question 10

An administrator is configuring Identity Awareness on a Check Point Security Gateway using the Captive Portal method. The organization wants to ensure that users who authenticate via the portal are correctly identified and that their identities are used in security policies. Which two actions are necessary to enable this? (Choose two.)

Accepted Answer

Configure the Captive Portal to use Local Authentication or an external authentication server such as RADIUS.. Captive Portal requires an authentication method (local or external) and network access to the portal interface. These two actions enable users to authenticate and be identified. Installing endpoint agents or using AD Query/Identity Collector are not necessary for the Captive Portal method, as it is designed to work without endpoint software and uses its own authentication flow.

Answer

Configure the gateway to use the Identity Collector for real-time identity updates.

Answer

Enable AD Query to synchronize user groups from Active Directory.

Answer

Install a Check Point Identity Agent on each user workstation.

Question 11

A security engineer configures a Threat Prevention profile with Threat Emulation enabled for PDF files. Users report that some PDF files are not being emulated, and the logs show the action 'Bypass' with the reason 'File size exceeds limit'. The engineer wants to ensure all PDFs are inspected without overloading the gateway. What is the most appropriate action?

Accepted Answer

Increase the 'Maximum file size for emulation' in the Threat Emulation blade settings to a value that accommodates the largest PDFs, while monitoring gateway performance.. Threat Emulation bypasses files that exceed the configured maximum size to protect gateway resources. To inspect larger PDFs, the administrator must increase this limit in the Threat Emulation settings. However, because emulation is CPU and memory intensive, the limit should be raised cautiously with performance monitoring. Other options describe non-existent features or incorrect offloading to ThreatCloud.

Answer

Enable 'Threat Emulation for large files' in the gateway's global properties, which automatically compresses files before emulation to stay under the size limit.

Answer

Disable the 'Bypass files larger than' option in the Threat Prevention profile, which will force all files to be emulated regardless of size.

Answer

Configure a file size exception in the Threat Prevention policy for PDF files, specifying that they should be sent to ThreatCloud for emulation instead of local emulation.

Question 12

An administrator has a ClusterXL High Availability cluster with two members. The primary member fails, and the secondary member becomes active. After the primary member is repaired and rebooted, it does not become active again, even though it has a higher priority. The administrator checks and finds that the cluster is in High Availability mode and priorities are correctly set. What is the most likely reason for this behavior?

Accepted Answer

The cluster is configured with 'ClusterXL HA' mode but the 'Preempt' option is disabled in the cluster properties.. In ClusterXL High Availability mode, preemption is not enabled by default. Even if a member has a higher priority, it will not automatically become active after recovery unless the 'Preempt' option is enabled in the cluster properties. This setting ensures that the higher-priority member takes over when it becomes available. The other options are either unlikely or contradicted by the scenario details.

Answer

The secondary member has a higher member ID, causing it to retain the active role.

Answer

The primary member's synchronization interface is down, preventing it from learning the current state and preempting.

Answer

The primary member's priority is set to a lower value than the secondary member's priority.

Question 13

A security analyst is reviewing logs and sees multiple entries indicating that files were sent to Threat Emulation but the verdict was 'Malicious'. However, the files were not blocked. What is the most likely cause?

Accepted Answer

The Threat Prevention policy is configured in 'Detect' mode instead of 'Prevent' mode.. When Threat Prevention is set to 'Detect' mode, malicious files are logged but not blocked. This mode is often used during initial deployment or testing. To enforce blocking, the policy must be changed to 'Prevent' mode. The logs clearly show detection without prevention, pointing to the policy mode as the cause.

Answer

Threat Emulation only detects but never blocks; blocking is handled by another blade.

Answer

The files were allowed because the user has administrator privileges and bypassed the policy.

Answer

The gateway is not licensed for Threat Emulation, so it only logs and does not block.

Question 14

A security administrator is setting up a VPN tunnel between two Check Point Security Gateways. The administrator wants to ensure that only specific services are allowed through the tunnel, while all other traffic is blocked. Which Check Point feature should be used to enforce this?

Accepted Answer

Security Policy rules that match the VPN community and specify the allowed services.. To allow only specific services through a VPN tunnel, you must create Security Policy rules that match the VPN community as the source and destination, and specify the allowed services. The default rule should block all other traffic. This ensures that only the desired services are permitted. The encryption domain defines which traffic is encrypted, but the security policy defines what is allowed.

Answer

VPN Community with 'Encryption Domain' set to the specific services.

Answer

VPN Community with 'Disable NAT inside the VPN Community' enabled.

Answer

VPN Community with 'Shared Secret' and 'Perfect Forward Secrecy' enabled.

Question 15

An administrator is configuring a VPN tunnel between a Check Point Security Gateway and a third-party gateway. The third-party gateway uses a certificate signed by an internal CA. The administrator wants to use certificate-based authentication. Which step is required on the Check Point gateway to trust the third-party certificate?

Accepted Answer

Import the third-party root CA certificate into the Check Point gateway's trusted CA list.. Certificate-based VPN authentication requires that each peer trusts the CA that signed the other's certificate. On the Check Point gateway, you must import the third-party root CA certificate into the trusted CA list. This allows the gateway to validate the certificate presented by the third-party during IKE. Without this trust, the negotiation fails. The process is done via SmartConsole or the command line, and the CA certificate must be in PEM or DER format.

Answer

Configure the VPN community to use 'Pre-Shared Secret' and manually enter the third-party's certificate fingerprint.

Answer

Add the third-party gateway's IP address to the 'Trusted Clients' list in SmartConsole.

Answer

Enable 'Certificate Authority' on the Check Point gateway and issue a certificate to the third-party gateway.
