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 2

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 3

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 4

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 5

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.

Question 6

When deploying an FTD in a virtual environment, what is the primary role of the 'GigabitEthernet0/0' interface by default?

Accepted Answer

Management interface.. In most virtual FTD deployments, the first interface is typically reserved for the management or diagnostic connectivity.

Answer

Failover link.

Answer

Data transit.

Answer

State link.

Question 7

In the context of FTD, what does 'FMC' stand for?

Accepted Answer

Firepower Management Center. FMC is the central management platform for FTD devices.

Answer

Firewall Management Console

Answer

Firewall Monitoring Center

Answer

Firepower Managed Cloud

Question 8

An engineer is troubleshooting a stateful failover issue in a Cisco Secure Firewall Threat Defense Active/Standby high availability pair. The firewall units are passing data traffic, but failover state synchronization fails. Which dedicated interface must be verified for correct physical connectivity and configuration?

Accepted Answer

The Failover and State Link. In a Cisco Secure Firewall Threat Defense Active/Standby high availability pair, stateful failover requires a dedicated Failover and State Link to synchronize state information (such as connection tables and VPN state) between the units. If data traffic passes but failover state synchronization fails, this dedicated link must be verified for physical connectivity and correct configuration.

Answer

The Cluster Control Link (CCL)

Answer

The Management Interface (eth0)

Answer

The Diagnostic Interface

Question 9

Which TWO protocols or mechanisms are used to integrate Cisco Identity Services Engine (ISE) with Cisco Secure Firewall Threat Defense? (Choose two)

Accepted Answer

SXP. Cisco ISE integrates with Secure Firewall using pxGrid (for identity/context sharing) and SXP (for SGT tag and IP mapping propagation).

Answer

NetFlow v5

Answer

LDAP direct bind

Answer

SNMPv1

Question 10

Which THREE steps are part of a standard FTD upgrade workflow managed via the FMC?

Accepted Answer

Upload the upgrade package to the FMC. Option C is correct because the standard FTD upgrade workflow managed through the FMC begins by uploading the FTD software upgrade package (image) to the FMC, which then stages it for deployment to managed devices. Option E is correct because after the package is available, the administrator selects the target device(s) in the FMC's Upgrade management page to initiate and schedule the upgrade. Option D is correct because the workflow includes running a readiness/health check on the device and reviewing and approving the resulting health check report before proceeding with the actual upgrade. Options A and B are incorrect: manually deleting all existing access rules is not a step in the upgrade workflow and would disrupt policy, and running a factory reset on the FTD is not part of a standard upgrade—it would wipe the configuration rather than upgrade the software.

Answer

Manually delete all existing access rules

Answer

Run a factory reset on the FTD

Question 11

You are deploying a Cisco Secure Firewall Threat Defense in an existing core network as an out-of-band intrusion prevention system. Which NGIPS deployment mode should you configure to ensure the firewall performs deep packet inspection and generates alerts without dropping any production traffic in the event of a device failure or high load?

Accepted Answer

Passive deployment mode using a SPAN or tap source. Passive deployment mode using a SPAN or tap source copies traffic to the Threat Defense without placing it inline in the forwarding path, so deep packet inspection and alerts occur without any risk of dropping production traffic. Even if the device fails or is overloaded, the production network is unaffected because traffic never flows through the firewall. This matches the requirement for out-of-band IPS with zero traffic impact.

Answer

Transparent mode with inline bypass enabled

Answer

Inline deployment mode with fail-open enabled

Answer

Routed mode with asymmetric routing tolerance

Question 12

An engineer is configuring an Identity Policy in FMC to enforce user-based access control. Active Directory integration has been established via User Agent, but the engineer notices that some users authenticated via remote access VPN are not being resolved to their IP addresses. Which feature must be integrated into the identity configuration to capture IP-to-user mappings for remote access VPN users?

Accepted Answer

Cisco Identity Services Engine (ISE) via pxGrid or RADIUS Accounting. Remote access VPN users are authenticated by the VPN headend (e.g., Cisco ASA/FTD or ISE), and their IP-to-user mappings are not learned by the User Agent, which relies on Active Directory security event log parsing on domain controllers. To capture these mappings, FMC must integrate with Cisco ISE via pxGrid or receive RADIUS Accounting records, which provide the user-to-IP binding at the time of VPN session establishment. This allows the Identity Policy to resolve VPN users to their assigned IP addresses.

Answer

FMC Captive Portal

Answer

Terminal Services Agent (TS Agent)

Answer

SNMP polling of the DHCP server

Question 13

When deploying a Cisco Secure Firewall Threat Defense device, what is the purpose of configuring Security Zones?

Accepted Answer

To logically group one or more interfaces together for simplified Access Control Policy application.. Security Zones on FTD are used to logically group one or more interfaces together so that Access Control Policies can be applied to the zone rather than individual interfaces. This simplifies policy management and allows consistent enforcement across multiple interfaces that share the same security posture.

Answer

To establish High Availability stateful synchronization between primary and secondary nodes.

Answer

To assign VLAN IDs to physical switch ports connected to the firewall.

Answer

To encrypt traffic passing between interfaces belonging to different zones using IPsec.

Question 14

When you have multiple overlapping NAT rules, which rule is applied?

Accepted Answer

The first matching rule. The FTD matches NAT rules using a top-down approach, similar to Access Control rules.

Answer

The rule that matches the interface

Answer

The rule with the lowest priority

Answer

The most specific rule

Question 15

In an FTD cluster, what happens if the cluster control link fails?

Accepted Answer

The cluster nodes may disable themselves to avoid split-brain.. If the control link fails, the cluster members cannot synchronize state or status, typically leading to a split-brain scenario or the standby nodes disabling themselves to prevent inconsistency.

Answer

The FMC takes over the cluster.

Answer

The cluster continues to operate normally.

Answer

The entire cluster reboots.

Question 16

You are deploying a Cisco Secure Firewall Threat Defense in transparent mode. How are frames forwarded between the internal and external interfaces of the firewall?

Accepted Answer

By bridging frames at Layer 2 based on destination MAC addresses within a configured Bridge Group.. In transparent mode, the FTD forwards frames at Layer 2 by bridging based on destination MAC addresses within a configured Bridge Group. The firewall does not perform IP route lookups or decrement TTL; it acts like a Layer 2 switch with security inspection. This allows the firewall to be inserted into an existing network without changing IP addressing.

Answer

By encapsulating all packets inside GRE tunnels between the ingress and egress ports.

Answer

By translating all private IP addresses to public IP addresses using NAT overload.

Answer

By performing IP route lookups and decrementing the TTL on every packet.

Question 17

A network engineer needs to configure Auto NAT on a Firepower Threat Defense device managed by FMC to translate internal subnet 10.10.10.0/24 to a single public IP address 203.0.113.50. Which translation type should be selected?

Accepted Answer

Dynamic PAT (Port Address Translation). Dynamic PAT (Port Address Translation) is the correct choice because it translates multiple internal IP addresses to a single public IP address using unique source ports. This allows the entire 10.10.10.0/24 subnet to share one public IP, which is the typical use case for PAT. Static NAT would require a one-to-one mapping, and Dynamic NAT would require a pool of public IPs.

Answer

Static NAT

Answer

Static Identity NAT

Answer

Dynamic NAT

Question 18

An administrator is troubleshooting an FTD device that is failing to register with FMC. The FTD has been configured with the correct FMC IP address, registration key, and NAT ID. Which additional setting must be verified on the FTD to allow successful registration?

Accepted Answer

The FTD must have a default route to reach the FMC.. The FTD requires a route to reach FMC. If FMC is on a different network, a default gateway or static route must be configured on the management interface. Without it, registration packets cannot reach FMC. DNS, time zone, and NAT ID are either already addressed or not blocking registration in this scenario.

Answer

The FTD must be able to resolve the FMC's hostname via DNS.

Answer

The FTD must be configured with the same NAT ID as the FMC.

Answer

The FTD must have the same time zone as the FMC.

Question 19

An administrator needs to create a variable set to define specific port or network variables used within Intrusion Rules. Where are variable sets managed in the FMC?

Accepted Answer

Objects > Object Management > Variable Sets. In FMC, variable sets used by Intrusion Rules are managed under Objects > Object Management > Variable Sets. This is where administrators define variables such as $HOME_NET, $EXTERNAL_NET, and port variables that Snort rules reference. The variable sets are then applied to the Intrusion Policy.

Answer

Devices > Device Management > Variables

Answer

System > Localized Variables

Answer

Policies > Access Control > Variables

Question 20

A security requirement mandates that QoS be applied to limit bandwidth for guest users. Where is QoS configured on an FMC-managed FTD?

Accepted Answer

In a separate QoS Policy. QoS policies are defined as a separate policy type in the FMC and then applied to the Access Control Policy.

Answer

Within the Access Control Policy rules

Answer

Under the Platform Settings

Answer

In the Prefilter Policy
