300-710 SNCF Practice Test 3 — 10 Questions

Question 1

An administrator is investigating an issue where connection events are failing to reach the FMC from a managed FTD. Which THREE daemons or logs on the FTD and FMC should be checked to troubleshoot event transport and communication issues? (Choose three)

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

Accepted Answer

FTD event streaming and SFIMS logs. Option A is correct because the FTD's event streaming process and SFIMS (the Firepower Management Center communication agent) are responsible for generating and forwarding connection events to the FMC, so their logs directly reveal whether events are being produced and transmitted. Option C is correct because /var/log/cisco/sftunnel.log records the status of the sftunnel (Secure Firewall Tunnel) connection between the FTD and FMC; if this tunnel is down or flapping, event transport will fail. Option E is correct because on the FMC, the event collection and correlator components receive and process events, and their logs (for example /var/log/messages or application logs under /var/sf/log) show whether events arrive and are ingested. Option B is not relevant because /var/log/dhcpd.log pertains to DHCP daemon activity, which has nothing to do with FTD-to-FMC event transport. Option D is not relevant because /var/log/samba/smb.log relates to SMB/CIFS file-sharing services, which are unrelated to Firepower event communication.

Answer

/var/log/dhcpd.log

Answer

/var/log/samba/smb.log

Question 2

You need to configure link redundancy on a Cisco Secure Firewall Threat Defense pair using EtherChannel (Port Channel) across multiple physical interfaces. When configuring LACP (IEEE 802.3ad) for the port channel interface via the Firepower Management Center (FMC), which requirement must be met for successful negotiation?

Accepted Answer

Both the FTD and the connected switch must be configured in LACP active mode or one must be active and the other passive.. LACP (IEEE 802.3ad) requires that at least one side of the link be in active mode for the protocol to negotiate. The valid combinations are active/active or active/passive; passive/passive will never form a bundle because neither side initiates LACP PDUs. On FTD managed by FMC, the port channel must be set to active or passive consistently with the switch side to bring the EtherChannel up.

Answer

The Port Channel must be configured in static mode (ON) regardless of the upstream switch settings to avoid LACP PDUs dropping.

Answer

The EtherChannel must use Source-Destination IP hashing exclusively, as MAC-based hashing is unsupported on FTD.

Answer

LACP fast rate (1-second timer) is mandatory for FTD clustering but optional for standalone firewalls.

Question 3

Which of the following must be identical on both units of an FTD high availability pair to ensure successful synchronization?

Accepted Answer

Software versions.. Both units must have the same model, software version, and license capabilities for the HA configuration to function correctly.

Answer

The management IP addresses.

Answer

The number of configured VLANs.

Answer

Physical serial numbers.

Question 4

An administrator is configuring high availability for Cisco Secure Firewall Threat Defense using Cisco FMC. Which TWO configuration steps are required during the initial setup of an Active/Standby HA pair? (Choose two)

Accepted Answer

Configure a dedicated failover interface and IP address scheme for stateful heartbeat communication.. Option A is correct because an Active/Standby Threat Defense HA pair requires a dedicated failover link (a physical interface or subinterface) with its own IP addressing scheme, over which the units exchange heartbeat and stateful failover messages. Option D is correct because, during HA configuration in FMC, the administrator must designate which chassis is the Primary unit and which is the Secondary unit, which determines failover precedence and role assignment. Option B is incorrect because HA management interfaces must use static IP addresses on the same subnet, not DHCP, so each unit retains a stable, unique management address for FMC communication. Option C is incorrect because both HA peers must run the same firewall mode (both routed or both transparent); mismatched modes are not supported. Option E is incorrect because stateful failover synchronization should remain enabled so that connections and state tables are replicated to the standby unit for seamless failover.

Answer

Configure the management interfaces to use DHCP so the standby unit can adopt the primary IP address.

Answer

Ensure both units are configured in different firewall modes (one routed, one transparent).

Answer

Disable stateful synchronization to improve failover switching speed.

Question 5

Which of the following is a limitation when deploying an FTD in transparent mode?

Accepted Answer

It does not support dynamic routing protocols.. Transparent mode does not support dynamic routing protocols (like OSPF or BGP) because it acts as an L2 bridge.

Answer

It does not support NAT.

Answer

It cannot handle VLAN tags.

Answer

It requires manual ARP entries for all hosts.

Question 6

Which feature in FMC allows you to group multiple physical interfaces into a single logical zone for policy assignment?

Accepted Answer

Security Zone. Security Zones allow logical grouping of interfaces for easier policy management.

Answer

VLAN Group

Answer

Port Channel

Answer

Bridge Group

Question 7

An administrator integrates Cisco Secure Firewall Management Center with Cisco ISE via pxGrid. After successful registration, the administrator wants to create an Access Control policy rule that blocks traffic from users in the 'Contractors' Security Group Tag. Where in the FMC rule creation wizard should the administrator configure this condition?

Accepted Answer

In the Access Control Rule, navigate to the Users tab and select the desired Security Group Tag.. In FMC Access Control policies, user and tag-based criteria are added under the 'Users' tab of the rule configuration, where Security Group Tags learned via pxGrid can be selected.

Answer

In Objects > Object Management > Access Control > SGT Objects.

Answer

In the Platform Settings policy under Identity Sources.

Answer

In the Access Control Rule, navigate to the Networks tab and select Security Groups.

Question 8

You are deploying FTD in a cloud environment. What is the primary purpose of the 'Management Interface' when launching the virtual instance?

Accepted Answer

To communicate with the FMC.. The management interface is used exclusively for the FMC or FDM to configure and manage the FTD appliance. Data traffic is kept separate to maintain security and throughput.

Answer

To provide high availability heartbeats.

Answer

To perform stateful inspection of internal traffic.

Answer

To handle internet-bound traffic.

Question 9

An administrator is preparing an upgrade plan for an FMC and its managed FTD devices. Which THREE best practices should be followed during the upgrade process to minimize downtime and avoid failure? (Choose three)

Accepted Answer

Take a complete backup of the FMC and export device configurations prior to starting the upgrade.. Option A is correct because taking a full FMC backup and exporting FTD configurations before any upgrade provides a rollback point if the upgrade fails or corrupts data, which is essential for minimizing downtime. Option B is correct because Cisco's upgrade best practice requires the FMC to be upgraded to the target version first, since a newer FMC can manage older FTD versions but an older FMC cannot manage newer FTD devices, avoiding management incompatibility. Option C is correct because running the pre-upgrade checker (e.g., via the FTD CLI or the FMC upgrade readiness check) identifies blockers such as unsupported configurations, insufficient disk space, or deprecated features before the upgrade begins. Option D is incorrect because factory resetting FTD devices after pushing an upgrade would erase the configuration and cause an outage, not minimize downtime. Option E is incorrect because the sftunnel is the management tunnel between FMC and FTD; disabling it permanently would break management and prevent the FMC from pushing the upgrade or policies, and it is not a valid upgrade practice.

Answer

Factory reset all FTD devices immediately after pushing the upgrade package.

Answer

Disable the sftunnel service permanently during the upgrade to prevent packet inspection.

Question 10

You are troubleshooting a port channel failure on an FTD device. The port channel is 'Up/Down'. What is the most likely cause?

Accepted Answer

Mismatched LACP configuration.. An 'Up/Down' status for a port channel usually indicates that LACP negotiation is failing between the FTD and the connected switch.

Answer

Insufficient license.

Answer

The FTD is in transparent mode.

Answer

Physical cable damage.
