300-710 SNCF Integration — 15 Questions

Question 1

An engineer is troubleshooting an eStreamer integration between Cisco FMC and a third-party SIEM. The SIEM client script successfully connects to the FMC eStreamer port (8302), but no events are being received. Where should the engineer verify the eStreamer client certificate and access rights on the FMC?

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

Accepted Answer

Navigate to System > Integration > eStreamer on the FMC to manage client certificates and allowed IP addresses.. To allow an eStreamer client to connect, the administrator must generate an eStreamer certificate and client configuration file on the FMC using the 'sftunnel' or eStreamer configuration utility in System > Integration > eStreamer, ensuring the client is explicitly authorized.

Answer

Modify the Access Control Policy advanced settings to allow eStreamer traffic through the Snort inspection engine.

Answer

Configure the external Automation policy under Objects > Object Management > eStreamer.

Question 2

Which syslog facility and severity level configuration is recommended when exporting standard firewall audit and connection events from Cisco Secure Firewall Threat Defense to a SIEM?

Accepted Answer

Syslog facility mail with severity debug. Secure Firewall Threat Defense allows administrators to configure syslog forwarding specifying standard facilities (such as local0 through local7) and appropriate severity levels (such as informational or warnings) under Platform Settings.

Question 3

Which menu path in the Cisco Secure Firewall Management Center is used to configure syslog export policies for managed FTD devices?

Accepted Answer

Policies > Access Control > Logging. Platform Settings policies on the FMC contain the configuration options for syslog servers, event logging, and platform-level services for FTD devices.

Answer

System > Integration > Syslog

Answer

Objects > Object Management > Syslog Servers

Question 4

An organization integrates Cisco Secure Firewall Threat Defense with Cisco SecureX (now Cisco Security Cloud Control / Cisco XDR) for threat intelligence and incident response. When investigating an indicator of compromise (IoC) on SecureX, an administrator triggers a block action for a malicious file hash. How is this block action enforced across the managed Secure Firewall Threat Defense devices?

Accepted Answer

The FMC receives the SecureX API notification and automatically pushes an update to the Security Intelligence Blacklist and File Control policies on the FTD.. When an observable (such as a file hash or IP) is blocked via Cisco SecureX threat intelligence/threat response integration, the FMC receives the pivot or API call and automatically updates the Security Intelligence Blacklist or File Control policy objects on the managed FTD devices.

Answer

SecureX uses NETCONF to directly modify the running configuration of the FTD data plane, bypassing the FMC.

Answer

The FTD devices poll Cisco SecureX directly every 60 seconds via secure syslog to retrieve updated file hashes.

Answer

The action requires the administrator to manually export a Snort rule from SecureX and import it into the FMC Advanced Malware Protection (AMP) policy.

Question 5

An administrator configures Cisco Secure Firewall Threat Defense to send connection logs to a syslog server. However, the syslog server receives logs with source IP addresses belonging to the FMC management interface rather than the FTD data interface IP address. What is the correct way to ensure syslog messages are sent directly from the FTD data or management interface as intended?

Accepted Answer

Configure the specific syslog server settings under Platform Settings > Syslog on the FMC and designate the desired egress interface for alert generation.. In Platform Settings > Syslog, administrators can define the syslog server configuration and explicitly select whether the syslog packets originate from the management interface or a specific data interface (Security Intelligence/Routing configuration).

Answer

Configure a NAT exemption rule on the FTD to prevent translation of syslog traffic destined for the SIEM.

Answer

Modify the Snort engine configuration file via Expert Mode to rewrite the source IP of exported syslog packets.

Answer

Enable 'Reliable Syslog' under System > Preferences on the FMC.

Question 6

An administrator wants to stream security events, connection events, and intrusion events from Cisco Secure Firewall Management Center (FMC) to a third-party SIEM platform. Which built-in protocol and feature on the FMC should be configured to export these events in real-time?

Accepted Answer

eStreamer. The eStreamer (Event Streamer) API and service on the FMC allows external applications and SIEMs to securely stream connection, intrusion, host, and malware events from the FMC database.

Answer

pxGrid

Answer

NETCONF

Answer

RADIUS Accounting

Question 7

An administrator is integrating Cisco Secure Firewall Threat Defense with Cisco Identity Services Engine (ISE) using Platform Exchange Services (pxGrid). Which service must be enabled and running on the ISE nodes for pxGrid communication to succeed?

Accepted Answer

Cisco pxGrid Service. pxGrid must be enabled on the designated ISE nodes so that Cisco Secure Firewall Threat Defense can subscribe to user identity and session updates.

Answer

IPAM Synchronization Service

Answer

RADIUS Accounting Service

Answer

TACACS+ Authentication Service

Question 8

A network security engineer configures Cisco Secure Firewall Threat Defense to ingest Security Group Tags (SGTs) from Cisco ISE via pxGrid. The integration is active, and SGTs are successfully mapped to IP addresses. However, access control rules referencing Security Group Tags fail to match traffic originating from authenticated endpoints. What is the most likely cause of this behavior on FTD?

Accepted Answer

The TrustSec SXP peering is not configured between the FTD and the authenticator switch, causing the firewall data plane to drop or ignore inline SGT headers.. For SGTs to be enforced in Access Control policies on FTD, the SGT metadata must be preserved in the data plane (such as through inline SGT propagation using Cisco TrustSec SXP or inline tagging). If SXP is not configured to propagate the tags across routed hops, or if the interface is not configured to trust SGT headers, FTD will not inspect the tag in the packet header.

Answer

Cisco Secure Firewall Threat Defense does not support enforcement of SGTs learned via pxGrid; it only supports SXP.

Answer

The Identity Source Sequence on ISE must include Active Directory LDAP bindings specifically for FTD rule evaluation.

Answer

The FMC requires a manual restart of the Snort detection engine every time a new SGT is learned via pxGrid.

Question 9

An administrator is integrating Cisco Secure Firewall Threat Defense with Cisco Identity Services Engine (ISE) using pxGrid. During the initial connection phase, the Secure Firewall is stuck in a 'Connecting' state and fails to download user-to-IP mapping. Where should the administrator check the pxGrid client status and troubleshoot the registration certificate handshake on the Secure Firewall CLI?

Accepted Answer

Run the command 'show pxgrid status' and 'show crypto ca certificates' in the FTD expert mode or CLI.. On Secure Firewall Threat Defense (managed via FMC), the pxGrid client runs as part of the FTD platform services. Troubleshooting pxGrid connection issues requires checking the fxos/platform or system logs, specifically using the command 'show pxgrid status' and verifying the PKI certificates issued by ISE under the security-client framework.

Answer

Inspect the 'estreamer.log' file on the FMC to view ISE pxGrid heartbeat failures.

Answer

Run 'show ise identity source' on the FMC CLI to confirm active pxGrid threads.

Answer

Check the Platform Settings policy under 'Cisco Identity Services Engine' and review the 'show sgt-mapping' command.

Question 10

Which menu path in the Cisco Secure Firewall Management Center (FMC) is used to configure the connection to Cisco Threat Response or Cisco SecureX?

Accepted Answer

System > Integration > SecureX. Integration with Cisco SecureX (Threat Response) is configured under System > Integration on the FMC interface.

Answer

Devices > Device Management > Threat Intelligence

Answer

Objects > Object Management > Cloud Services

Answer

Policies > Access Control > Security Intelligence

Question 11

An enterprise integrates Cisco Secure Firewall Management Center with Cisco ISE using pxGrid for identity-based access control. The security team notices that user identity mapping works for domain users authenticating via 802.1X, but guest users connecting through a WebAuth portal do not have their user-to-IP mappings populated on the FTD. What is the root cause of this issue?

Accepted Answer

The pxGrid connection on ISE is not subscribed to the guest session topic, or guest session publishing is disabled in ISE deployment settings.. Guest users authenticated via WebAuth on ISE may not have active pxGrid session directory notifications if the guest profile or ISE profiler service is not configured to publish guest sessions, or if the pxGrid node is not subscribed to guest session topics (such as 'Session Directory' guest events).

Answer

FMC requires an active eStreamer connection to ingest guest identities because pxGrid only supports Active Directory domain accounts.

Answer

Guest users must manually log into a captive portal hosted on the FTD data plane before ISE can share their identity.

Answer

The FTD identity policy must be configured with a RADIUS server group instead of pxGrid to support guest VLANs.

Question 12

An administrator is configuring third-party SIEM integration using eStreamer. The external client application encounters a TLS handshake failure when attempting to connect to the FMC eStreamer port. What is the standard troubleshooting step to resolve certificate validation issues between an external eStreamer client and the FMC?

Accepted Answer

Generate a new pkcs12 client certificate bundle from the FMC eStreamer configuration menu and import it into the client application store.. When setting up an external eStreamer client, the administrator must generate a PKCS#12 (.pfx or .pem) client certificate bundle and copy the corresponding CA certificate to the client host so that mutual TLS authentication succeeds.

Answer

Disable SSL/TLS verification in the FMC Platform Settings under the eStreamer daemon parameters.

Answer

Restart the Snort inspection engine on all managed FTD devices.

Answer

Change the eStreamer listening port from 8302 to 443 in the FMC System Preferences.

Question 13

When configuring Cisco Secure Firewall Threat Defense to forward syslog messages to a remote SIEM receiver, which transport layer protocols are natively supported for syslog export?

Accepted Answer

UDP and TCP. Cisco Secure Firewall Threat Defense supports both UDP and TCP (including reliable syslog over TCP) for transmitting syslog messages to external SIEMs.

Answer

HTTP and HTTPS only

Answer

UDP only

Answer

TCP and SCTP

Question 14

An engineer configures Cisco Secure Firewall Threat Defense to ingest context from Cisco ISE using pxGrid. The integration status on the FMC shows 'Connected', but when inspecting user identities via the FTD CLI using 'show user-identity user', no active users appear. Which CLI command should the engineer use to troubleshoot the pxGrid session feed specifically at the FTD process level?

Accepted Answer

Access the expert mode shell and check the identity daemon logs or execute 'show idedb statistics'.. To troubleshoot low-level pxGrid and identity agent behavior on Secure Firewall Threat Defense, engineers use diagnostic shell commands such as 'pmtool' or checking the identity daemon logs located in /var/log/Cisco/identity or running 'show idedb' commands.

Answer

Run 'clear pxgrid cache' from the FTD privileged EXEC mode.

Answer

Run 'debug crypto pxgrid' from the FMC CLI.

Answer

Execute 'show threat-response status' on the FTD.

Question 15

An organization uses Cisco Secure Firewall Threat Defense and integrates with Cisco ISE for identity policies. The security team notices that identity rules are intermittently failing because the FTD cache of IP-to-user mappings is being flushed unexpectedly. Upon investigation, what condition on FTD or ISE typically causes the purging of active user identity maps?

Accepted Answer

Receipt of an accounting stop message from the authenticator or an explicit session termination event from ISE pxGrid.. User identity mappings on FTD can be purged or invalidated due to RADIUS accounting stop messages, explicit pxGrid session termination notices from ISE (such as logoff or re-authentication timeouts), or when the maximum session idle timer expires on the firewall identity policy configuration.

Answer

A mismatch in the NTP time synchronization greater than 5 minutes between the FTD and the FMC.

Answer

Exceeding the FMC database storage limit for event logging.

Answer

Automatic daily rotation of the FMC administrator password.
