300-710 SNCF Deployment Practice Test 4 — 15 Questions

Question 1

Which THREE features must be configured to successfully implement static route tracking on an FTD device?

Accepted Answer

Track ID association with the route. Static route tracking requires a monitor object, a tracking command associated with that monitor, and a static route that references the track ID.

Answer

BGP peer group

Answer

Multicast routing enabled

Question 2

An engineer is deploying a pair of Cisco Secure Firewall Threat Defense appliances in a data center. Management wants a firewall cluster that can forward traffic at line rate on all members simultaneously without requiring a separate load balancer, and they need the cluster to survive the failure of the master unit without manual intervention. Which clustering mode should the engineer implement?

Accepted Answer

Individual interface clustering with Distributed forwarding mode. Distributed mode in a FTD cluster allows every member to actively forward traffic on its own interfaces, so throughput scales with the number of appliances without an external load balancer. The cluster automatically elects a new master if the current master fails, providing the uninterrupted redundancy the data center requires.

Answer

Active/Standby failover with stateful link and interface monitoring

Answer

Active/Active failover with asymmetric flow handling enabled

Answer

Spanned EtherChannel clustering with a single management IP

Question 3

An engineer is deploying a Cisco Secure Firewall Threat Defense device at a remote branch and needs to stage the device so it can be discovered by the management center before any data interfaces are configured. The branch uses a single DHCP-assigned uplink on the management interface. Which deployment approach should be used to allow the management center to onboard the device with zero-touch provisioning?

Accepted Answer

Enable zero-touch provisioning on the management center, then add the device using its serial number and have the device initiate a connection to the management center over the internet.. Zero-touch provisioning is designed for exactly this situation: the branch device has only a DHCP uplink and no preconfigured data interfaces, so the management center adds the device by serial number and the device initiates the outbound connection. This avoids inbound reachability and manual CLI steps, which is why the serial-number-based onboarding approach satisfies the zero-touch requirement.

Answer

Configure a DHCP server on the branch uplink to hand the device an IP address and then manually run the configure manager add command with the registration key.

Answer

Deploy the device in transparent mode and use the management center's discovery task to scan the branch subnet for the device's management IP address.

Answer

Configure a local management bootstrap file with the management center's IP address, NAT ID, and registration key, then let the device reach out to the management center over the data uplink.

Question 4

An engineer is preparing to register a Cisco Secure Firewall Threat Defense (FTD) device to a Firepower Management Center (FMC) using the CLI. The FTD management interface is on the 10.10.10.0/24 network, the FMC is reachable at 10.10.20.50, and the FTD management IP is 10.10.10.5 with a default gateway of 10.10.10.1. After issuing the configure manager add command, the registration fails because the FTD cannot resolve the FMC key. Which action should the engineer take to complete registration successfully?

Accepted Answer

Issue the configure manager add 10.10.20.50 <registration_key> command on the FTD and then add the FTD to the FMC using the same key.. The configure manager add command on the FTD specifies the FMC IP and a registration key, and the same key is then entered in FMC when adding the device. This creates the management trust and completes registration. The other options either use invalid commands, unnecessary settings, or the wrong mechanism for FMC onboarding.

Answer

Enable the FTD REST API and then add the FMC as a manager using the web interface on port 443.

Answer

Configure a static route on the FTD to the FMC network and then use the register manager command to push the key to the FMC.

Answer

Run the configure manager add DONTRESOLVE <registration_key> command and then register the FTD in FMC using its hostname.

Question 5

An engineer is preparing to register a new Cisco Secure Firewall Threat Defense (FTD) appliance with Cisco Secure Firewall Management Center (FMC). The FTD will be managed through its management interface, which is reachable from the FMC on the same management network. The engineer wants to add the device using the FMC device registration workflow. Which command must be run on the FTD CLI before the device can be successfully added to FMC?

Accepted Answer

configure manager add

. Registering an FTD with FMC requires the configure manager add command on the FTD CLI, specifying the FMC hostname or IP address and a shared registration key. The optional NAT ID supports deployments where FTD is behind NAT. Once this command is issued, FMC can discover and register the device using the same key, after which policies can be assigned and deployed.

Answer

configure manager add

Answer

configure manager add

Answer

configure manager add

Question 6

A security team is deploying a Cisco Secure Firewall Threat Defense cluster in spanned EtherChannel mode across two switches. During validation, the team observes that the cluster units do not form a single logical device and traffic is not load-balanced. Which configuration element is required for the cluster control link to function correctly in this topology?

Accepted Answer

The cluster control link must be configured as a port-channel with the same EtherChannel mode and VLAN on both switches, and the cluster interface must reference that port-channel.. Spanned EtherChannel clustering requires the cluster control link to be a port-channel that is consistently configured on both switches and referenced by the cluster interface. This consistency allows heartbeat and state messages to flow between units regardless of which switch they are attached to, enabling the units to form a single logical device and support load balancing.

Answer

The cluster control link must be configured as a dedicated physical interface on each unit, not as a port-channel, to carry heartbeat and state messages.

Answer

The cluster control link must be a separate Layer 2 network with jumbo frame support and must not be shared with data traffic.

Answer

The cluster control link must be configured with a static route to the management center so that state updates can be relayed through the management network.

Question 7

An engineer is deploying a Cisco Secure Firewall Threat Defense cluster in spanned EtherChannel mode across two switches. The design requires that the cluster survive the failure of a single switch without losing the ability to forward traffic, and that the cluster use a single logical interface for each data interface. Which two switch-side configuration elements are required to support this deployment? (Choose two.)

Accepted Answer

Configure the switch ports as a port-channel with LACP in active mode on both switches. A spanned EtherChannel cluster relies on a port-channel formed with LACP across the switches, and the ports must be trunks that permit the required VLANs with a consistent native VLAN. These two elements provide both the link redundancy and the multi-VLAN transport needed for the cluster to keep forwarding if one switch fails.

Answer

Configure the switch ports as access ports in a single VLAN with no trunking

Answer

Ensure both switches are configured with the same EtherChannel load-balancing hash algorithm

Answer

Configure the port-channel on each switch with a unique channel-group number that matches the FTD cluster interface

Question 8

An engineer is configuring a Cisco Secure Firewall Threat Defense (FTD) device in transparent mode. The FTD is deployed between a router and a switch, and the engineer wants to allow specific traffic while blocking all other traffic. The management interface is already configured and the device is registered to FMC. Which statement describes how the FTD handles traffic in transparent mode?

Accepted Answer

The FTD acts as a Layer 2 bridge and requires an access control policy to permit traffic; without a permit rule, traffic is blocked by the default action.. In transparent mode, the FTD bridges traffic at Layer 2 and enforces access control policies. To allow specific traffic and block the rest, the engineer configures permit rules for desired traffic and sets the default action to block. The FTD does not route traffic in this mode, so static routes are not used for the bridged flows.

Answer

The FTD acts as a Layer 2 bridge and requires a prefilter policy to permit traffic; without a prefilter rule, all traffic is dropped before access control.

Answer

The FTD acts as a Layer 2 bridge and automatically allows all traffic unless an explicit block rule is configured, because the default action is permit.

Answer

The FTD acts as a Layer 3 router and requires static routes for each connected subnet to forward traffic between interfaces.

Question 9

An administrator is deploying a Cisco Secure Firewall Threat Defense device in a small branch office. The device will be managed locally without FMC. The administrator needs to perform the initial setup, including configuring the management IP address and enabling the device for local management. Which interface is used by default for initial device setup and management access on an FTD appliance?

Accepted Answer

The Management0/0 interface. The Management0/0 interface is the dedicated out-of-band management interface on FTD appliances. It is used for initial setup, has a default IP address, and provides ongoing management access separate from data traffic. This separation improves security and simplifies management in branch deployments where FMC is not used.

Answer

The Console port

Answer

The GigabitEthernet0/0 data interface

Answer

The Diagnostic interface

Question 10

An engineer is deploying a Cisco Secure Firewall Threat Defense (FTD) device in a high-availability pair using Active/Standby failover. The engineer must ensure that failover occurs properly and that traffic continues to flow after a failure. Which two statements are true about the requirements for this deployment? (Choose two.)

Accepted Answer

A dedicated failover link and a state link must be configured between the two FTD devices.. Active/Standby failover requires both units to run the same software version and have compatible resources. A failover link and a state link are also required to exchange control messages and synchronize connection state. These ensure that the standby can take over seamlessly and maintain traffic flow after a failure.

Answer

The standby FTD must have a different hostname and IP address on all data interfaces to avoid conflicts.

Answer

The management interface of both FTD devices must be on the same subnet as the FMC.

Answer

Both FTD devices must be registered to different FMCs to avoid management conflicts.

Question 11

An administrator is troubleshooting a Stateful High Availability (HA) pair of Cisco Secure Firewall 4100 series devices managed by FMC. The units are failing to form an HA state, and logs indicate a state mismatch on the control link. Which underlying cause is most likely preventing the HA synchronization?

Accepted Answer

One unit is running a slightly different maintenance patch release of FTD than its peer.. For FTD stateful HA to form and synchronize, both units must run the identical software version, including the same maintenance patch release. A mismatch in patch level causes the control link state to fail because the HA state machine and configuration synchronization protocol versions differ between peers. The logs indicating a state mismatch on the control link are consistent with this version incompatibility.

Answer

The MTU on the data interfaces differs by 4 bytes.

Answer

The stateful HA control link is configured across a routed switch interface instead of a direct cross-over cable.

Answer

The management IP addresses on the active and standby units are identical.

Question 12

An engineer is configuring static route tracking on a Cisco Secure Firewall Threat Defense to ensure high availability for outbound internet connectivity. A backup static route is configured with a higher metric. What mechanism does the firewall use to dynamically switch from the primary route to the backup route when the primary next-hop fails?

Accepted Answer

Bidirectional Forwarding Detection (BFD) or ICMP ping SLA trackers that monitor the next-hop IP.. Static route tracking on Cisco Secure Firewall Threat Defense uses SLA monitors — either BFD or ICMP ping — to track the reachability of the next-hop IP. When the tracked object goes down, the primary static route is removed from the routing table and the backup route with the higher metric is installed, providing dynamic failover.

Answer

STP topology change notifications received on the tracked interface.

Answer

FMC heartbeat loss detection between the firewall and the gateway.

Answer

Automatic generation of dynamic OSPF neighbor adjacencies over the static interface.

Question 13

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 14

You are configuring an active/standby High Availability pair for Cisco Secure Firewall Threat Defense using FMC. You need to configure port channels for the data interfaces to increase bandwidth and redundancy. Which guideline must be followed regarding port channels in an HA deployment?

Accepted Answer

The port channel interfaces on both the primary and secondary units must have identical interface IDs and member port compositions.. In a Cisco Secure Firewall Threat Defense HA deployment, port channels must be configured identically on both the primary and secondary units — same interface IDs and same member port composition — so that failover preserves the link aggregation and the standby unit can take over seamlessly. This is a documented guideline for EtherChannel in HA.

Answer

LACP active mode is unsupported on HA secondary units; static port channels must be used instead.

Answer

Port channels are restricted to transparent mode HA configurations only.

Answer

Port channels can only be configured on the active unit; the standby unit automatically inherits them via stateful sync.

Question 15

An enterprise network design incorporates Equal-Cost Multi-Path (ECMP) routing across two Cisco Secure Firewall Threat Defense units functioning independently in routed mode. What is the primary benefit of enabling ECMP on the firewalls?

Accepted Answer

It enables the firewall to balance outbound traffic across multiple next-hop gateways using multiple equal-cost routes.. ECMP allows the firewall to install multiple equal-cost paths to the same destination in its routing table, distributing traffic across multiple next-hop routers for load balancing and redundancy.

Answer

It allows passive NGIPS interfaces to share inspection load without SPAN replication.

Answer

It pools the CPU and memory resources of both firewalls into a single logical cluster.

Answer

It synchronizes connection state tables across both independent firewalls for zero-loss failover.
