300-710 SNCF Deployment Practice Test 2 — 15 Questions

Question 1

A network security engineer is setting up a high availability (HA) pair for two Cisco Secure Firewall Threat Defense devices managed by Cisco FMC. Which prerequisite condition must be met between the primary and secondary units before configuring the HA pair?

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

Accepted Answer

Both units must have different management IP addresses assigned to their respective management interfaces.. Before configuring an HA pair, both units must have the same exact model, identical license configurations, the same software version, and identical interface configurations/naming.

Answer

The primary unit must be configured in routed mode while the secondary unit is in transparent mode.

Answer

The secondary unit must be running a newer software version than the primary unit to support failover synchronization.

Answer

The data interfaces must use dynamic DHCP addressing to ensure seamless failover state transfer.

Question 2

An administrator is deploying Cisco Secure Firewall Virtual in a Microsoft Azure environment using automated templates. The deployment requires multiple network interfaces for management, internal, and external zones. How does Azure assign IP configurations to these virtual network interfaces (NICs)?

Accepted Answer

Azure assigns IP configurations via DHCP directly to each attached virtual NIC, which must correspond to the FMC interface settings.. In Microsoft Azure, each virtual NIC attached to a VM receives its IP configuration via DHCP from the Azure fabric, and the assigned addresses must match what is configured on the corresponding FMC interface objects. Azure does not allow arbitrary static IP assignment inside the guest OS for the primary IP configuration; the address is defined in the NIC's IP configuration in Azure and delivered via DHCP. This is why the FMC interface settings must align with the Azure-assigned IPs.

Answer

Azure relies on stateful ARP broadcasts to dynamically allocate IPs to virtual firewall subinterfaces.

Answer

IP addresses must be manually hardcoded inside the cloud-init script using API tokens.

Answer

The firewall assigns static IP addresses to the Azure fabric controllers via BGP peering.

Question 3

An engineer is preparing to deploy a Cisco Secure Firewall Threat Defense cluster in an enterprise data center. Which THREE requirements must be verified and configured prior to cluster initialization? (Choose three)

Accepted Answer

A dedicated high-speed, low-latency Cluster Control Link (CCL) must be connected between all nodes.. Option A is correct because the Cluster Control Link (CCL) is a dedicated, high-speed, low-latency network that carries cluster heartbeats, state synchronization, and forwarded traffic between nodes, and it must be connected between all cluster members before initialization. Option B is correct because Cisco Secure Firewall clustering requires all members to be the exact same physical or virtual model with identical interface counts and types so that configuration and failover behavior remain consistent across the cluster. Option E is correct because data interfaces on each cluster unit must be connected to upstream and downstream switches using EtherChannel/Port Channels, which the cluster uses as the distributed data plane for traffic forwarding and load balancing. Option C is incorrect because all cluster members must operate in the same firewall mode (routed or transparent); mixing modes across master and slave nodes is not supported. Option D is incorrect because all cluster members must run the same compatible software version, not different versions, to ensure consistent clustering behavior and avoid incompatibilities.

Answer

The cluster master must be configured in transparent mode while slave nodes operate in routed mode.

Answer

Each cluster member must run a different software version to prevent simultaneous kernel panics.

Question 4

An administrator is deploying a Cisco Secure Firewall Threat Defense High Availability pair. During the initial configuration in Cisco FMC, the administrator assigns specific priority values. How does the failover process use the primary and secondary unit designations and priorities?

Accepted Answer

The active unit is chosen based on health status, preemption settings, and designated failover priorities.. In an Active/Standby HA pair, the unit configured with the higher priority or designated role determines preemption and active state behavior when both units boot up simultaneously.

Answer

Both units actively share the workload in an active-active load-balanced state.

Answer

The unit designated as Primary always becomes Active, ignoring preemption or health status.

Answer

The unit with the lowest management IP address is automatically elected as Active.

Question 5

An administrator is deploying a new Cisco Secure Firewall Threat Defense device and needs to ensure that the firewall performs layer 3 routing while keeping the existing subnet architecture completely transparent to the upstream router. Which firewall mode must be selected during initial configuration?

Accepted Answer

Transparent mode. In transparent mode, the firewall acts like a Layer 2 bridge. The upstream and downstream networks remain in the same subnet, making the firewall transparent to layer 3 routing.

Answer

Inline mode

Answer

Routed mode

Answer

Passive mode

Question 6

When deploying Cisco Secure Firewall Threat Defense in transparent mode, which TWO operational characteristics or restrictions apply to the deployment? (Choose two)

Accepted Answer

The firewall bridges traffic at Layer 2 between interfaces belonging to the same BVI bridge group.. Option C is correct because in transparent mode the Cisco Secure Firewall Threat Defense (FTD) operates as a Layer 2 bridge: interfaces are assigned to a Bridge Virtual Interface (BVI) bridge group, and traffic is switched between member interfaces within that same bridge group without modifying the IP header. Option E is correct because transparent mode is designed as a bump-in-the-wire Layer 2 device, so dynamic routing protocols such as OSPF and RIP cannot be run across the transparent interfaces (routing must occur on devices outside the firewall). Option A is incorrect because transparent interfaces do not require unique public routable IP addresses; the BVI typically holds a management IP, and the bridged interfaces themselves are not routed addresses. Option B is incorrect because the FTD in transparent mode is not required to be the primary DHCP server for downstream VLANs; DHCP server duties are not an inherent requirement of transparent deployment. Option D is incorrect because NAT is not fully supported across transparent interfaces; NAT is generally a routed-mode feature, and transparent mode does not support the full range of NAT translations.

Answer

Every physical interface must be configured with a unique public routable IP address.

Answer

The firewall must act as the primary DHCP server for all downstream VLANs.

Answer

Network Address Translation (NAT) is fully supported for changing IP addresses across interfaces.

Question 7

You are configuring a Cisco Secure Firewall Threat Defense deployment in an AWS environment. Which specific component is required to handle automated failover and route table updates when deploying a clustered or high-availability pair across multiple Availability Zones?

Accepted Answer

Cisco Secure Firewall AWS Lambda scripts. AWS deployments of Cisco Secure Firewall Threat Defense rely on AWS Lambda functions triggered by cloud watch events or API calls to automatically update route tables during a failover event.

Answer

Cisco Adaptive Security Virtual Appliance (ASAv) state synchronization protocol

Answer

BGP peering directly with the AWS Internet Gateway

Answer

Gratuitous ARP via the transit gateway

Question 8

A security engineer is deploying a Cisco Secure Firewall Threat Defense device inline in front of a critical server farm. The goal is to inspect all incoming and outgoing traffic for intrusions without modifying the IP addressing schema of the servers. Which interface mode should be configured on the FTD device?

Accepted Answer

Inline mode with a bypass capability. Inline mode places the firewall directly in the path of traffic, allowing it to inspect, drop, or modify packets while operating transparently or via routed configurations.

Answer

Passive mode

Answer

SPAN mode

Answer

Promiscuous mode

Question 9

You are deploying a Cisco Firepower Threat Defense (FTD) unit in transparent mode. Which requirement must be met for the device to process traffic correctly in this mode?

Accepted Answer

The device does not require an IP address on its interfaces to forward traffic.. Transparent mode requires the FTD to be configured with a management IP address, but it acts as a Layer 2 device where interfaces do not require IP addresses for traffic forwarding.

Answer

Each interface must have a unique IP address assigned within the same subnet.

Answer

The FTD must be configured with a management IP address for traffic forwarding.

Answer

The upstream router must be configured with a static ARP entry for the FTD management IP.

Question 10

When deploying a Cisco Secure Firewall Threat Defense virtual appliance (FPRv) in a public cloud environment such as Microsoft Azure, which TWO architectural considerations or limitations must be accounted for? (Choose two)

Accepted Answer

User-Defined Routes (UDRs) in Azure must be configured to point traffic destined for other subnets to the FTDv internal interface IP.. Option A is correct because in Azure the platform does not automatically route traffic between subnets through a firewall appliance; User-Defined Routes (UDRs) must be created on the relevant subnets with the next-hop set to the FTDv's internal (data) interface IP so that inter-subnet and egress traffic is inspected by the firewall. Option B is correct because the FTDv in Azure requires a minimum of three network interfaces — Management, Inside (internal), and Outside (external) — each attached to separate Azure subnets, since the management interface cannot carry data-plane traffic and the inside/outside separation is mandatory for the firewall's routing and security zones. Option C is wrong because the FTDv management interface is dedicated and cannot be shared with data-plane traffic, regardless of any bandwidth optimization setting. Option D is wrong because Azure does not support the Layer 2 broadcast/multicast and dedicated failover/control links that on-premises physical clustering relies on; FTDv in Azure uses a different HA mechanism (e.g., Azure-based failover with UDR/API manipulation) rather than native physical clustering. Option E is wrong because dynamic routing protocols such as BGP are supported on FTDv in public clouds (and are commonly used with Azure Route Server or VPN gateways), so the claim that they are entirely unsupported is false.

Answer

The FTDv management interface can be shared with the data plane traffic if bandwidth optimization is enabled.

Answer

Physical clustering using dedicated control interfaces is natively supported in Azure just like on-prem hardware.

Answer

Dynamic routing protocols (BGP/OSPF) are entirely unsupported on virtual appliances deployed in public clouds.

Question 11

Which TWO interface modes are available when configuring an intrusion prevention (NGIPS) security policy on a Cisco Secure Firewall Threat Defense device? (Choose two)

Accepted Answer

Inline mode. Inline mode (C) is correct because a Cisco Secure Firewall Threat Defense NGIPS security policy can be deployed in inline (inline interface set) mode, where traffic passes through the device and the sensor can drop malicious packets in real time. Passive mode (E) is also correct because the NGIPS can be deployed passively, monitoring a copy of traffic (for example via SPAN or a tap) and generating alerts/blocking via other means without being inline. The other options do not belong: 'Bridged Layer 4 mode' (A) is not an NGIPS interface mode, 'NAT-patrolled mode' (B) is not a valid mode, and 'Promiscuous trunk mode' (D) is not an interface mode offered for NGIPS policy configuration.

Answer

Bridged Layer 4 mode

Answer

NAT-patrolled mode

Answer

Promiscuous trunk mode

Question 12

Which THREE of the following are valid requirements or characteristics when deploying Cisco Secure Firewall Threat Defense in a high availability (HA) configuration? (Choose three)

Accepted Answer

Both units must run the exact same software version and maintenance patch level.. Option C is correct because Cisco Secure Firewall Threat Defense HA requires both peers to run identical software versions and maintenance patch levels; mismatched versions prevent the HA pair from forming or staying healthy. Option D is correct because a dedicated physical interface (the failover link) must be configured to carry HA control and state-synchronization traffic between the units, separate from the data interfaces. Option E is correct because HA peers must be the same hardware model, such as two FPR-1010 appliances, ensuring identical interface layout and capabilities. Option A is not valid because transparent mode HA does not support asymmetric routing across active and standby units simultaneously; traffic must traverse the active unit consistently. Option B is not valid because HA units must match in hardware resources, including RAM, not merely CPU core count.

Answer

Transparent mode HA supports asymmetric routing paths across both active and standby units simultaneously.

Answer

The active and standby units can have differing amounts of RAM as long as the CPU core counts match.

Question 13

You are configuring High Availability for two FTD devices. Which TWO conditions must be met for a successful failover state? (Choose two)

Accepted Answer

The devices must use different management IP addresses.. FTD failover requires identical hardware/software and specific link configuration for state synchronization.

Answer

The failover link must be connected to a public-facing switch.

Answer

The standby unit must have a higher priority value than the active unit.

Answer

The devices must use different serial numbers.

Question 14

You are deploying a Cisco Secure Firewall in transparent mode. Which requirement must be met to ensure the appliance can successfully pass traffic between two directly connected subnets?

Accepted Answer

Define a Bridge Group and assign interfaces to it, ensuring the device is in Layer 2 mode.. In transparent mode, the firewall acts as a Layer 2 device. It requires a management IP address for communication but does not route traffic. It processes traffic based on L2 segments.

Answer

Configure the firewall as the default gateway for the subnets.

Answer

Enable dynamic routing protocols on the bridge interface.

Answer

Configure an IP address on each physical interface participating in the bridge group.

Question 15

You are deploying a high-availability pair of Firepower Threat Defense (FTD) units. Which TWO requirements must be met to ensure stateful failover functions correctly?

Accepted Answer

Both units must be running the exact same version of FTD software.. Stateful failover requires a dedicated link and matching hardware/software configurations.

Answer

The failover link must be connected to a dedicated management port.

Answer

The standby unit must be configured with a different hostname.

Answer

The failover interface must be configured as a physical interface for redundancy.
