CCSM Practice Test 14 — 15 Questions

Question 1

A security administrator is reviewing logs and notices that the Anti-Bot blade is not inspecting traffic on a specific network segment. The administrator confirms that the segment is routed through the gateway and that the Anti-Bot blade is enabled globally. What is the most likely reason for this behavior?

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

Accepted Answer

The network segment is excluded from inspection by a policy rule in the Threat Prevention policy.. Threat Prevention policies are rule-based and can include exceptions that bypass inspection for specific sources, destinations, or services. If a rule excludes the network segment, Anti-Bot will not inspect its traffic even if the blade is enabled globally. The administrator should check the policy rule base for any exclusions and remove or modify them as needed.

Answer

The Anti-Bot blade requires a separate license for each network segment.

Answer

Anti-Bot only inspects traffic on port 80 and 443, and the segment uses a different port.

Answer

The gateway is in a cluster and the segment is only routed through the standby member.

Question 2

A remote access user reports that the Mobile Access VPN client connects, but internal web applications are unreachable. The administrator confirms the user authenticates successfully and receives an IP address from the Office Mode pool. Which action should the administrator take to diagnose why traffic is not reaching internal resources?

Accepted Answer

Check that the Office Mode network is included in the VPN domain and that a firewall rule permits traffic from the Office Mode pool to the internal servers.. The Mobile Access client successfully authenticated and received an Office Mode IP, which indicates the VPN tunnel is established. Connectivity to internal resources then depends on the Office Mode network being part of the VPN domain so return traffic is encrypted, and on a firewall rule permitting the Office Mode pool to reach internal servers. Checking both items resolves the typical cause of this symptom.

Answer

Run 'vpn tu' on the gateway to list the IKE and IPsec SAs for the user's Office Mode IP.

Answer

Verify that the user's certificate has not expired and reissue it if necessary.

Answer

Increase the IKE Phase 1 lifetime on the Security Gateway to prevent rekeying during the session.

Question 3

A Check Point Security Gateway is experiencing intermittent VPN tunnel failures. The logs show 'Phase 2 completion failed' with the reason 'No proposal chosen'. Which of the following is the most likely cause?

Accepted Answer

The IPsec Phase 2 proposal (encryption and integrity algorithms) does not match between peers.. The 'No proposal chosen' error during Phase 2 completion indicates that the gateways could not agree on the IPsec parameters for the Phase 2 SA. This is most often caused by mismatched encryption or integrity algorithms in the Phase 2 proposal. Each gateway sends its list of supported proposals; if there is no common proposal, the negotiation fails. Verifying and aligning the Phase 2 proposals on both peers resolves the issue.

Answer

The VPN tunnel is blocked by a firewall rule.

Answer

The Phase 1 shared secret is incorrect.

Answer

The peer gateway is using a different Diffie-Hellman group for Phase 2.

Question 4

An administrator is troubleshooting a VPN tunnel that is not establishing between two Check Point Security Gateways. They suspect an issue with IKE negotiation. Which TWO commands are most appropriate to debug the IKE negotiation process? (Choose two.)

Accepted Answer

vpn debug trunc. The commands vpn debug ikeon and vpn debug trunc are both used to enable and manage IKE debugging. vpn debug ikeon starts logging IKE negotiation details, while vpn debug trunc truncates the log and can also start debugging. Together, they provide the necessary information to diagnose IKE failures. The other commands either show packet-level information without IKE payload or provide general VPN statistics, which are less useful for this specific issue.

Answer

fw ctl zdebug drop

Answer

cpstat -f vpn

Answer

fw monitor -e 'accept;'

Question 5

An administrator notices that a site-to-site VPN tunnel between two Check Point gateways frequently renegotiates Phase 2, causing brief interruptions. The log shows 'IKE Phase 2 rekey failed' messages. Which of the following is the most likely cause?

Accepted Answer

The Phase 2 lifetime values are mismatched, causing one peer to expire the SA before the other.. Phase 2 rekey failures often stem from mismatched IPsec SA lifetimes. When lifetimes differ, one gateway may attempt to rekey while the other still uses the existing SA, causing collisions or rejections. Aligning Phase 2 lifetimes and proposals on both peers is the direct fix. Other issues like PFS or Phase 1 mismatches would prevent the tunnel from coming up at all.

Answer

Perfect Forward Secrecy (PFS) is disabled on one peer and enabled on the other.

Answer

The Phase 1 lifetime values are mismatched on the two peers.

Answer

The IKE Phase 1 encryption algorithms are different on the two peers.

Question 6

A security administrator is tuning a Check Point R81 Security Gateway that protects a high-traffic web server farm. The administrator wants to ensure that files downloaded by users are inspected by Threat Emulation without introducing excessive latency for files that are unlikely to contain malicious content. Which Threat Emulation configuration setting should the administrator adjust to control the maximum file size sent for emulation?

Accepted Answer

Set the 'Max File Size' parameter in the Threat Emulation blade configuration to an appropriate value.. The Max File Size setting in the Threat Emulation blade is specifically designed to control the upper limit of file size that will be sent for sandbox analysis. By setting this parameter appropriately, the administrator can avoid emulating very large files that are less likely to be malicious and could cause performance degradation, thus optimizing both security and latency.

Answer

Adjust the 'File Size Limit' in the Anti-Virus blade's profile settings.

Answer

Modify the 'ThreatCloud' connection timeout setting in the gateway's global properties.

Answer

Configure the 'Emulation Queue Size' in the gateway's kernel parameters.

Question 7

An administrator is deploying a new R81 Security Gateway with Threat Prevention blades. The administrator needs to ensure that Threat Emulation and Threat Extraction work together to protect against zero-day threats in email attachments. Which TWO of the following statements accurately describe the combined operation of these blades? (Choose two.)

Accepted Answer

Threat Extraction sanitizes attachments before delivery, while Threat Emulation analyzes the original file in a sandbox.. Threat Extraction and Threat Emulation are complementary. Threat Extraction immediately sanitizes files to remove active content, providing a safe version for users. Meanwhile, Threat Emulation analyzes the original file in a sandbox to detect unknown malware. If malicious, the file is blocked, but the sanitized version may still be delivered. This dual approach ensures both immediate and dynamic protection.

Answer

Threat Extraction and Threat Emulation cannot be enabled on the same gateway due to performance constraints.

Answer

Threat Extraction requires Threat Emulation to be disabled to function properly.

Answer

Threat Emulation only scans files that have been sanitized by Threat Extraction.

Question 8

An administrator is hardening a Threat Prevention policy against zero-day exploits. The goal is to reduce exposure to unknown exploits while limiting false positives on business-critical applications. Which TWO measures are appropriate for this objective? (Choose two.)

Accepted Answer

Enable the relevant IPS protections, including those marked as high confidence for the affected services, and set the profile to Prevent.. Hardening against zero-day exploits calls for complementary layers. Enabling high-confidence IPS protections in Prevent mode blocks known exploitation techniques on the services in use, while Threat Emulation detonates unknown files delivered to critical hosts and blocks malicious ones. Scoping emulation to critical hosts manages performance, and high-confidence IPS keeps false positives low, together reducing exposure without broadly exempting valuable assets.

Answer

Add broad exceptions for all protections on business-critical servers to eliminate any chance of false positives.

Answer

Rely solely on Anti-Bot to block command-and-control callbacks, since exploit traffic is always part of a botnet.

Answer

Disable IPS protections rated as low confidence to reduce noise, leaving only medium and high confidence enabled.

Question 9

A Check Point Security Gateway is configured for a site-to-site VPN with a third-party gateway. The tunnel is up, but users cannot access resources across the VPN. You suspect a Phase 2 (IPsec) issue. Which of the following would you check first to ensure that the encryption domains are correctly configured?

Accepted Answer

Verify that the encryption domain of the local gateway includes all internal subnets that should be accessible.. In a site-to-site VPN, the encryption domain defines the subnets that are protected. If the local encryption domain is incomplete, traffic from a missing subnet will not be encrypted or accepted by the peer. This is a common cause of traffic failure even when the tunnel is up. Checking and correcting the encryption domain on both gateways ensures that all necessary subnets are included and match, allowing traffic to flow.

Answer

Verify that the peer gateway's certificate is valid and not expired.

Answer

Ensure that Perfect Forward Secrecy (PFS) is enabled on both gateways.

Answer

Check that the IKE Phase 1 proposal matches the peer's proposal.

Question 10

A Check Point Security Gateway in a site-to-site VPN environment is configured with multiple external interfaces. After a recent ISP change, the VPN tunnel intermittently fails to establish, and the logs show 'Received notification from peer: INVALID-ID-INFORMATION'. Which action should you take first to resolve this issue?

Accepted Answer

Check the VPN community configuration and ensure the peer's identity matches the actual external IP address.. The INVALID-ID-INFORMATION notification during IKE Phase 1 indicates that the identity (ID) sent by the peer does not match what the local gateway expects for that peer. In Check Point, the peer identity is typically derived from the configured IP address. An ISP change likely changed the external IP, causing a mismatch. Verifying and updating the peer's identity in the VPN community ensures the gateway accepts the peer's ID and allows the tunnel to establish.

Answer

Disable Perfect Forward Secrecy (PFS) to simplify the negotiation.

Answer

Verify that the peer gateway's certificate is not expired.

Answer

Increase the IKE Phase 1 lifetime to allow more time for negotiation.

Question 11

An administrator is configuring a new Security Gateway in a Check Point environment. They want to ensure that the gateway can be managed by the Management Server and that policy can be installed. After configuring the gateway object in SmartConsole, they initiate SIC (Secure Internal Communication). The SIC status remains 'Not Communicating'. Which action should the administrator take FIRST to troubleshoot this issue?

Accepted Answer

Verify that the one-time password entered during SIC initialization matches the activation key defined in the gateway object.. SIC initialization requires that the one-time password entered on the gateway matches the activation key configured in the gateway object. If they differ, the trust cannot be established, and the status remains 'Not Communicating'. Checking this match is the quickest and most common first step. Other steps like verifying IP addresses or reinitializing SIC are secondary and should be done only after confirming the activation key.

Answer

Verify that the gateway's IP address is correctly configured in the gateway object.

Answer

Reinitialize SIC on the gateway and reset the SIC trust on the Management Server.

Answer

Check the SIC trust state on both the Management Server and the gateway using the command 'cpstat mg' on the management and 'cpstat fw' on the gateway.

Question 12

A security analyst is investigating a series of alerts from the Anti-Bot blade. The logs show that an internal host is repeatedly connecting to a domain that resolves to multiple IP addresses, and the connections use HTTP with a User-Agent string that changes on each request. The analyst suspects a botnet using domain generation algorithm (DGA) and fast-flux techniques. Which Check Point feature would provide the most direct evidence to confirm this suspicion?

Accepted Answer

Anti-Bot's DNS reputation and domain analysis, including DGA detection and fast-flux indicators.. Anti-Bot's DNS reputation and domain analysis capabilities are designed to detect DGA and fast-flux by examining domain names and their resolution behavior. This includes identifying domains that appear algorithmically generated and tracking IP address changes associated with a single domain. Such analysis provides direct evidence to confirm the analyst's suspicion.

Answer

Threat Emulation reports showing the behavior of files downloaded from the domain.

Answer

Identity Awareness logs showing the user associated with the internal host.

Answer

Threat Extraction logs showing the sanitization of files from the domain.

Question 13

An administrator configures a Star VPN community between a Check Point R81 gateway and a third-party peer. Phase 1 and Phase 2 complete, but the remote peer reports receiving packets with a source IP that does not match the negotiated selector, causing them to be dropped. The Check Point gateway shows the tunnel as up. Which Check Point mechanism is most likely rewriting the source address before encryption?

Accepted Answer

Hide NAT applied to the internal subnet by a rule above the VPN rule. The remote peer is rejecting inner packets whose source falls outside the negotiated traffic selectors, which points to address translation occurring before encryption. A Hide NAT rule positioned above the VPN rule in the security policy will translate the internal subnet to the gateway address, so the encrypted payload carries an unexpected source and the peer drops it despite a healthy tunnel.

Answer

Link Selection set to use the gateway's external interface address

Answer

IPsec tunnel management configured for route-based VPN

Answer

Automatic Static NAT configured on the gateway object

Question 14

An administrator is troubleshooting a site-to-site VPN where Phase 1 completes but Phase 2 fails. The log shows 'Quick Mode failed: no proposal chosen'. Which of the following is the most likely cause?

Accepted Answer

The Phase 2 encryption or integrity algorithms do not match between peers.. Phase 2 negotiation fails with 'no proposal chosen' when the two peers cannot agree on IPsec SA parameters. This is commonly due to mismatched encryption or integrity algorithms. Since Phase 1 is successful, the IKE SA is established, and the problem is isolated to the Phase 2 proposal. Verifying and aligning the Phase 2 settings on both gateways resolves the issue.

Answer

The VPN community is not configured with the correct encryption domain.

Answer

The pre-shared secret is incorrect.

Answer

The peer's IP address is not reachable.

Question 15

A Check Point administrator needs to verify whether IPsec traffic from a specific remote peer is being decrypted and passed to the internal network. The administrator has access to the gateway's command line. Which command provides a real-time capture of packets on the gateway's external interface, showing both encrypted and decrypted traffic?

Accepted Answer

fw monitor -e 'accept host 203.0.113.5;'. fw monitor is a Check Point diagnostic tool that captures packets at several inspection points, including before encryption and after decryption. It can filter by host, showing both the encrypted and decrypted versions of the traffic. This makes it ideal for verifying that packets from a remote peer are decrypted and forwarded internally.

Answer

tcpdump -i eth0 host 203.0.113.5

Answer

cpstat vpn

Answer

vpn debug ikeon
