300-710 SNCF Deployment Practice Test 8 — 15 Questions

Question 1

An administrator needs to deploy an FTD in inline mode for IPS functionality but must ensure that the traffic remains uninterrupted if the software process fails. Which feature should be enabled?

Accepted Answer

Configure the interfaces as a hardware bypass pair.. The fail-open feature (hardware bypass) on supported FTD interfaces ensures that traffic continues to flow even if the FTD software fails or reboots.

Answer

Set the FTD to passive mode.

Answer

Enable high availability failover.

Answer

Implement ECMP routing.

Question 2

You are configuring a high availability pair of FTDs. Which interface type is strictly reserved for state synchronization?

Accepted Answer

Dedicated Failover/State link. In a Cisco FTD high availability pair, a dedicated failover/state link is strictly reserved for state synchronization and HA control traffic. This link carries hello messages, unit state, and stateful inspection data between the active and standby units. It must be a dedicated interface separate from data and management traffic to ensure reliable, low-latency synchronization.

Answer

Management interface

Answer

Data interface

Answer

Diagnostic interface

Question 3

An FTD device is configured in routed mode. What must be configured to allow traffic to exit the network through the firewall?

Accepted Answer

A static route pointing to the gateway.. In routed mode, the FTD acts as a router; therefore, an upstream default route or specific static routes are required to forward traffic to the next hop.

Answer

An inline bypass pair.

Answer

A bridge group interface.

Answer

A passive monitoring interface.

Question 4

Which FTD deployment mode is best suited for an environment where the device should monitor traffic without performing any blocking or dropping actions?

Accepted Answer

Passive mode. Passive mode is specifically designed for monitoring traffic via a SPAN or TAP port without impacting traffic flow.

Answer

Transparent mode

Answer

Inline mode

Answer

Routed mode

Question 5

When deploying an FTD virtual appliance in AWS, which feature allows the FTD to scale horizontally to handle varying traffic loads?

Accepted Answer

Auto Scaling Groups.. In cloud environments, FTD virtual appliances can be deployed within an Auto Scaling group to handle dynamic traffic loads.

Answer

ECMP load balancing.

Answer

Clustering.

Answer

Stateful failover.

Question 6

You are troubleshooting high availability. The units are connected, but the failover link shows as 'Down'. What is the most likely cause?

Accepted Answer

Mismatched failover link configuration or physical layer issues.. The failover link must be a direct cable connection or a dedicated VLAN. Mismatched cable types or misconfigured link settings are common causes for the link to remain down.

Answer

The primary unit is in routed mode.

Answer

The standby unit has an expired license.

Answer

Mismatched IP addresses on the data interface.

Question 7

In which mode does the FTD firewall act as a Layer 3 hop and perform NAT?

Accepted Answer

Routed mode. Routed mode is the standard deployment mode where the FTD operates as a Layer 3 device and supports NAT and routing protocols.

Answer

Passive mode

Answer

Inline mode

Answer

Transparent mode

Question 8

You need to implement static route tracking on an FTD to ensure traffic fails over to a secondary ISP. Which object is used to define the reachability check?

Accepted Answer

SLA Monitor object. SLA Monitor objects are used to track reachability to a target IP, and the static route is then associated with this monitor.

Answer

Route map

Answer

Failover group

Answer

Interface tracking group

Question 9

When configuring an FTD cluster, what is the purpose of the Control Plane IP address?

Accepted Answer

To allow the FMC to manage the cluster as a single logical device.. The Control Plane IP allows the FMC to communicate with the entire cluster as a single entity, rather than needing to manage individual nodes separately.

Answer

To synchronize the configuration files across the cluster.

Answer

To handle user authentication traffic.

Answer

To serve as the default gateway for internal hosts.

Question 10

In an FTD high availability pair, what happens to the standby unit if it loses the heartbeat signal on the failover link?

Accepted Answer

It promotes itself to Active.. If the standby unit loses heartbeat signals from the active unit, it assumes the active unit has failed and initiates a failover transition to become the new active unit.

Answer

It reboots.

Answer

It remains standby.

Answer

It enters a 'Failed' state.

Question 11

You are deploying an FTD in a cloud environment and need to ensure high availability. Which technology is typically used to manage the virtual IP failover?

Accepted Answer

Cloud API calls to update route tables.. In cloud environments, FTD high availability failover is managed by cloud API calls that update route tables to redirect traffic from the failed instance to the standby instance. Because cloud providers like AWS and Azure do not support traditional Layer 2 protocols such as VRRP or gratuitous ARP for floating IPs, the FTD uses cloud-native mechanisms (e.g., AWS API calls to reassign an Elastic IP or update route tables) to achieve failover. This is the standard HA approach for FTDv in public clouds.

Answer

VRRP.

Answer

EtherChannel hashing.

Answer

Gratuitous ARP.

Question 12

Which FTD deployment mode must be selected to use the device as a transparent bump-in-the-wire for security inspection?

Accepted Answer

Transparent. Transparent mode allows the FTD to be inserted into a network without changing the IP scheme, acting as a bridge.

Answer

Hybrid

Answer

Passive

Answer

Routed

Question 13

When configuring a Port Channel on an FTD, what is the primary benefit of using LACP (Link Aggregation Control Protocol)?

Accepted Answer

It provides automated link negotiation and failure detection.. LACP ensures link integrity by performing negotiation and error checking, preventing misconfiguration in the bundle.

Answer

It increases the throughput limit.

Answer

It bypasses the need for an IP address.

Answer

It converts the port to a virtual switch.

Question 14

When deploying an FTD appliance, which interface role is used for receiving traffic from a SPAN port?

Accepted Answer

Passive interface. A passive interface is configured to monitor traffic without being part of the production traffic path, making it perfect for SPAN/TAP input.

Answer

Routed interface

Answer

Inline set

Answer

Bridge group interface

Question 15

When configuring ECMP (Equal-Cost Multi-Path) on FTD, what happens if one of the next-hop paths fails?

Accepted Answer

Traffic is automatically load-balanced across the remaining active paths.. FTD monitors the routes; if a path fails, the FTD removes that specific route from the routing table, and traffic is automatically redistributed across the remaining paths.

Answer

Traffic is dropped until manual intervention.

Answer

The entire cluster enters a maintenance mode.

Answer

All traffic is rerouted to the primary management interface.
