300-710 SNCF Deployment Practice Test 10 — 15 Questions

Question 1

Which TWO of the following are benefits of using a Port Channel on an FTD?

Accepted Answer

Improved link redundancy.. Option A is correct because a Port Channel (EtherChannel/LACP or static) bundles multiple physical interfaces into one logical interface, so if a member link fails, traffic continues over the remaining links, providing link redundancy without a topology change. Option E is correct because the bundled member links share traffic through the hashing algorithm, so the logical interface's throughput is the aggregate of its members, increasing total available bandwidth beyond a single link. Options B, C, and D are not benefits of a Port Channel: it does not inherently reduce latency, it does not eliminate spanning tree (STP still runs on the logical bundle and the FTD still participates in loop prevention), and it has nothing to do with automatic NAT mapping, which is a separate FTD NAT policy function.

Answer

Reduced latency.

Answer

Elimination of spanning tree.

Answer

Automatic NAT mapping.

Question 2

Which TWO of the following are valid high availability modes for FTD?

Accepted Answer

Active/Standby.. Option C (Active/Standby) is correct because FTD supports a stateful failover HA pair in which one unit actively passes traffic while the standby unit synchronizes connection and state information and takes over if the active unit fails. Option D (Clustering) is correct because FTD supports clustering, where multiple FTD devices are grouped into a single logical cluster to provide both high availability and increased throughput/scalability. The other options are not valid FTD HA modes: Active/Active (non-clustered) is not a supported FTD failover mode, Failover-on-demand is not an FTD HA configuration, and Load-Balanced Passive is not a recognized FTD high availability mode.

Answer

Active/Active (non-clustered).

Answer

Failover-on-demand.

Answer

Load-Balanced Passive.

Question 3

Which THREE considerations must be addressed when deploying FTDv in a public cloud?

Accepted Answer

Integration with cloud route tables for failover.. When deploying FTDv in a public cloud, integration with cloud route tables for failover (A) is required because FTDv cannot use traditional Layer 2 failover mechanisms; instead, failover is achieved by manipulating cloud provider route tables to redirect traffic to the standby instance. VPC security group constraints (B) must be addressed because security groups act as stateful virtual firewalls at the instance level and can block the management, data, and failover traffic that FTDv requires, so rules must be carefully configured. Cloud-specific instance sizing (C) is also essential because FTDv performance depends on the selected cloud instance type's CPU, memory, and network bandwidth, and supported instance sizes differ from on-premises hardware models. Hardware bypass capabilities (D) do not apply because public cloud instances have no physical network interface cards or hardware bypass pairs. Clustering using local control links (E) is not applicable because FTDv clustering in public clouds uses cloud-native constructs and does not rely on dedicated local control-link interfaces as on physical appliances.

Answer

Hardware bypass capabilities.

Answer

Clustering using local control links.

Question 4

Which TWO of the following are valid reasons to use Transparent Mode?

Accepted Answer

Simplified L2 insertion.. Option D is correct because Transparent Mode lets a firewall be inserted into an existing Layer 2 segment without requiring any IP addressing or routing changes, so deployment is a simple drop-in at the L2 level. Option E is correct because in Transparent Mode the device forwards traffic without acting as a router or NAT boundary, preserving the original source and destination IP addresses so the network remains address-transparent. Options A, B, and C are not valid reasons: Transparent Mode still inspects L3/L4 headers rather than ignoring them, it explicitly does not act as a Layer 3 gateway, and it does not provide dynamic routing, which requires an L3 interface and routing protocols.

Answer

To increase throughput by ignoring L3 headers.

Answer

To act as a Layer 3 gateway.

Answer

To enable dynamic routing.

Question 5

Which THREE factors affect the choice between deploying FTD in Routed vs Transparent mode?

Accepted Answer

Layer 2 vs Layer 3 placement.. Option A is correct because the fundamental decision between FTD Routed and Transparent mode hinges on whether the firewall is inserted as a Layer 3 hop (routed, with IP addresses on its interfaces) or as a Layer 2 bridge (transparent, forwarding traffic without modifying the IP topology). Option B is correct because Transparent mode is specifically designed for scenarios where existing IP addressing and subnets cannot be renumbered or changed, since it acts as a "bump in the wire" and preserves the current Layer 3 scheme. Option E is correct because Routed mode is required to perform NAT and to participate in dynamic routing protocols (such as OSPF, EIGRP, or BGP), whereas Transparent mode does not support NAT or dynamic routing and only forwards frames based on Layer 2 information. Option C is incorrect because the brand of the upstream switch is irrelevant — FTD interoperability does not depend on switch vendor. Option D is incorrect because the number of users is a sizing/scalability consideration, not a factor that determines Routed versus Transparent mode selection.

Answer

The brand of the upstream switch.

Answer

The number of users.

Question 6

Which THREE items are synchronized across an FTD high availability pair?

Accepted Answer

NAT tables.. HA synchronization includes NAT tables, connection/session states, and the system configuration policies.

Answer

Management interface IP.

Answer

Physical interface counters.

Question 7

Which TWO FTD interface types are commonly used for connectivity to an ISP?

Accepted Answer

Routed interface.. A routed interface (C) is correct because it is a Layer 3 interface configured with an IP address that can be used as the outside/egress interface toward an ISP, supporting static routes, DHCP client, and NAT. A sub-interface (E) is correct because it is a logical VLAN-tagged interface created on a physical or port-channel interface, commonly used when the ISP provides multiple VLANs or services over a single link (e.g., internet plus MPLS). The cluster control link (A) is wrong because it is a dedicated interface for inter-chassis clustering traffic, not ISP connectivity. A passive interface (B) is wrong because it is an interface where routing protocols are suppressed from sending updates, not a connectivity type to an ISP. A bridge group interface (D) is wrong because it is a Layer 2 bridging construct used to join interfaces into a bridge domain, not a typical ISP-facing Layer 3 interface.

Answer

Cluster control link.

Answer

Passive interface.

Answer

Bridge group interface.

Question 8

Which TWO components must be configured to manage an FTD via the FMC?

Accepted Answer

Registration key.. To manage an FTD via the FMC, the FTD must be configured with a registration key (Option A), which is a shared secret entered on both the FTD and the FMC to authenticate and authorize the device's addition to the FMC's inventory. The FTD must also have a management interface IP address (Option B) so that the FMC can reach the device over the network for initial registration and ongoing management communications. The default gateway on the data interface (Option C) is not required for FMC management because management traffic uses the dedicated management interface, not a data interface. A valid license on the FMC (Option D) is not a per-device configuration component needed to establish management, and an SNMP community string (Option E) is only for monitoring via SNMP, not for FMC management.

Answer

Default gateway on the data interface.

Answer

A valid license on the FMC.

Answer

SNMP community string.

Question 9

You are deploying a Cisco Firepower Threat Defense (FTD) device in transparent mode. Which requirement must be met to allow traffic flow through the firewall?

Accepted Answer

Configure a Bridge Group Virtual Interface (BVI) with an IP address for management.. In transparent mode, FTD acts as a Layer 2 device. It uses bridge groups, and traffic is bridged between interfaces. Since it is L2, the interfaces do not require IP addresses for routing, but the bridge group interface (BVI) needs an IP address for management purposes.

Answer

Define a default gateway on the upstream router pointing to the FTD MAC address.

Answer

Assign a unique IP address to each physical interface in the bridge group.

Answer

Enable dynamic routing protocols on all physical interfaces.

Question 10

You are configuring an NGIPS mode deployment on an FTD device. You need to ensure that the FTD can drop malicious traffic in real-time. Which mode must you select?

Accepted Answer

Inline Mode. Inline Mode places the FTD directly in the traffic path so packets must traverse the sensor, allowing it to drop malicious frames in real time before they reach the protected host. This is the only NGIPS deployment mode that supports blocking/drop actions; the other modes are detection-only.

Answer

Promiscuous Mode

Answer

Bypass Mode

Answer

Passive Mode

Question 11

You are deploying a Cisco FTD High Availability pair. During the synchronization process, what occurs when the standby unit fails to receive three consecutive heartbeat hellos from the primary?

Accepted Answer

The standby unit transitions to the Active state.. In FTD HA, three consecutive missed hellos trigger a state change, and the standby unit initiates a failover because it assumes the primary has failed.

Answer

The standby unit initiates a full configuration overwrite from the secondary flash.

Answer

The standby unit enters a suspended state to wait for administrative intervention.

Answer

The primary unit is rebooted automatically by the standby unit.

Question 12

In an FTD clustering deployment, how does the control plane communicate state information between the master and slave units?

Accepted Answer

Via the Control Link.. In FTD clustering, the Control Link (CL) is responsible for heartbeat and state synchronization between the master unit and the subordinate units.

Answer

Via the Management Interface.

Answer

Via the backplane bus protocol.

Answer

Via the Data Link.

Question 13

You are configuring static route tracking on an FTD device. What is the primary purpose of this configuration?

Accepted Answer

To ensure traffic is only routed through a verified path.. Static route tracking allows the firewall to monitor the availability of a path using ICMP or other probes and remove the route from the routing table if the probe fails.

Answer

To load-balance traffic across ISPs.

Answer

To increase the throughput of the interface.

Answer

To dynamically adjust the MTU of the link.

Question 14

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 15

When deploying an FTD virtual appliance on-prem using VMware ESXi, which virtual network adapter type is recommended for optimal performance?

Accepted Answer

VMXNET3. VMXNET3 is the recommended virtual network adapter type for Cisco Secure Firewall Threat Defense virtual appliances on VMware ESXi because it is a paravirtualized adapter designed for high performance, offering better throughput and lower CPU utilization than emulated adapters. It supports advanced features like multi-queue, checksum offload, and large receive offload, which are critical for a firewall processing high packet rates. Cisco documentation explicitly recommends VMXNET3 for FTDv deployments.
