300-710 SNCF Deployment Practice Test 11 — 15 Questions

Question 1

When using clustering with FTD, what is the 'Flow Owner' in the context of traffic distribution?

Accepted Answer

The unit that maintains the connection state for a specific flow.. In FTD clustering, the Flow Owner is the unit that owns and maintains the connection state (session table entry) for a specific flow. All packets of that flow are forwarded to the Flow Owner, which performs stateful inspection and maintains the connection. This ensures stateful failover and consistent policy enforcement across the cluster, since only one unit owns the flow at a time.

Answer

The master unit that manages the configuration.

Answer

Any unit that has the highest CPU availability.

Answer

The unit that performs the SSL decryption for the flow.

Question 2

Which component is mandatory for managing multiple FTD devices in a distributed enterprise deployment?

Accepted Answer

Firepower Management Center (FMC). Firepower Management Center (FMC) is the centralized management platform required to manage and orchestrate policies across multiple FTD appliances.

Answer

Cisco Secure Workload

Answer

Cisco DNA Center

Answer

Firepower Device Manager (FDM)

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

Which of the following must be identical on both units of an FTD high availability pair to ensure successful synchronization?

Accepted Answer

Software versions.. Both units must have the same model, software version, and license capabilities for the HA configuration to function correctly.

Answer

The management IP addresses.

Answer

The number of configured VLANs.

Answer

Physical serial numbers.

Question 5

Which TWO statements are true regarding NGIPS passive mode deployment?

Accepted Answer

It is transparent to the network traffic path.. In a passive NGIPS deployment, the sensor is not placed directly in the traffic path; instead it receives a copy of the traffic, so option B is correct because the device is transparent to the network and cannot affect forwarding. Option C is correct because that copy is delivered by connecting the sensor to a SPAN (mirror) port on a switch or to a network TAP, which replicates packets for monitoring. Option A is incorrect because an inline bypass switch is used for inline (fail-to-wire) deployments, not passive ones. Option D is incorrect because resetting connections requires the sensor to be inline or to send TCP resets via an inline-capable interface, which is not the passive monitoring model. Option E is incorrect because dual-homed physical interfaces are associated with inline or routed deployments, whereas passive mode typically uses a single monitoring interface.

Answer

It requires an inline bypass switch.

Answer

It can actively reset connections.

Answer

It requires dual-homed physical interfaces.

Question 6

In an FTD cluster, which unit is responsible for assigning flow ownership to other units in the cluster?

Accepted Answer

The master unit. The master unit in an FTD cluster handles management, orchestration, and the distribution/assignment of traffic flows to subordinate units.

Answer

The FMC

Answer

The subordinate unit

Answer

The external load balancer

Question 7

When considering virtual FTD deployments, which THREE factors significantly impact the performance of the instance?

Accepted Answer

The amount of provisioned RAM. Option B is correct because the amount of provisioned RAM directly determines how much memory the virtual FTD can use for connection tables, Snort/Snort 3 inspection buffers, and other runtime data structures; insufficient RAM causes packet drops and degraded throughput. Option D is correct because the virtual network adapter type (for example, VMXNET3 versus E1000, or SR-IOV versus paravirtualized) determines whether traffic is offloaded to hardware, how many queues are available, and how much CPU overhead is incurred per packet, all of which strongly affect instance performance. Option E is correct because the number of allocated CPU cores governs how many Snort inspection instances and other processes can run in parallel, directly scaling inspection throughput and the ability to handle concurrent flows. Option A is not correct because the number of configured Access Control Rules is a configuration/policy factor that affects rule lookup efficiency only marginally and is not one of the primary resource factors that determine virtual FTD instance performance. Option C is not correct because the number of active management sessions consumes only a small amount of control-plane resources and does not significantly impact the data-plane performance of the virtual FTD instance.

Answer

The number of configured Access Control Rules

Answer

The number of active management sessions

Question 8

Which TWO of the following are valid methods for deploying an FTD appliance?

Accepted Answer

As a virtual machine on ESXi. Option D is correct because Cisco Firepower Threat Defense (FTD) can be deployed as a virtual appliance on VMware ESXi, where it runs as a VM using the FTDv image with virtual NICs mapped to the host's vSwitches. Option E is correct because FTD is also available as a dedicated physical hardware appliance, such as the Cisco Firepower 1000, 2100, 4100, or 9300 series, where the FTD software runs directly on the appliance's hardware. Options A, B, and C are not valid deployment methods: FTD is not supported as a module inside a Nexus switch (that role belongs to the ASA/FTD module in a Catalyst 6500 or Firepower 4100/9300 chassis, not Nexus), it is not distributed as a Docker container, and it is not installed as an OS-level package on Windows Server.

Answer

As a hardware module inside a Cisco Nexus switch

Answer

As a Docker container on a Linux host

Answer

As an OS-level package on a Windows server

Question 9

Which THREE items are required to create a port channel on an FTD device?

Accepted Answer

LACP configuration. To create a port channel on an FTD device, you must configure LACP (option B), which is the link aggregation protocol used to negotiate and bundle the member links, and you need two or more physical interfaces (option C) to serve as the members of the EtherChannel. You also must create a logical Port-Channel interface (option E), which is the aggregated interface that receives the IP configuration and is referenced by policies and routing, with the physical interfaces assigned to it. A static route to the port channel (option A) is not required to build the port channel itself; routing is configured separately after the interface exists. A physical bypass module (option D) is a hardware fail-to-wire feature unrelated to forming a port channel and is not a prerequisite.

Answer

A static route to the port channel

Answer

A physical bypass module

Question 10

An engineer is deploying a pair of Cisco Secure Firewall Threat Defense appliances managed by a Firewall Management Center. The requirement is that the two appliances share a single management IP address and a single data IP address so that downstream routers only need one next-hop address, and failover must occur automatically when the active unit fails. Which deployment mode should the engineer configure?

Accepted Answer

Active/Standby failover. The requirement for one shared management IP, one shared data IP, and automatic takeover on failure maps directly to Active/Standby failover. In this mode the standby unit continuously synchronizes configuration and state so it can assume the active role and both addresses without operator intervention, giving downstream devices a stable single next hop.

Answer

Transparent mode with bridge groups

Answer

Standalone deployment with equal-cost multipath routing

Answer

Clustering with spanned EtherChannel

Question 11

An engineer is deploying Cisco Secure Firewall Threat Defense in a routed environment where the inside network uses private RFC 1918 addresses and the outside interface connects to an ISP. The requirement is that inside hosts can reach the internet, but the firewall must not translate traffic destined for an internal server farm that is also reachable through a secondary internal interface. Which configuration approach correctly meets this requirement?

Accepted Answer

Configure a manual NAT rule with the inside source networks translated to the outside interface address, and place a no-NAT (identity) rule above it for traffic destined to the internal server farm.. Selective translation requires ordered rules. A manual NAT policy lets the engineer place an identity rule for internal server farm destinations above a dynamic PAT rule for internet-bound traffic, so only the intended flows are translated. This ordering is the key to meeting both the translation and the exemption requirements in one policy.

Answer

Disable NAT control entirely and let the upstream ISP router perform translation for all inside traffic.

Answer

Rely solely on auto NAT applied to the inside interface object, because auto NAT automatically excludes internal destinations.

Answer

Apply dynamic identity NAT to all inside networks and use a policy-based route to redirect internet traffic to the ISP.

Question 12

A security team is deploying a Cisco Secure Firewall Threat Defense device in a data center where the requirement is to inspect traffic flowing between two Layer 3 segments without changing the IP addressing or routing of those segments. The firewall must sit logically between the two segments and forward traffic based on MAC addresses. Which deployment mode should be used?

Accepted Answer

Transparent mode with a bridge group. Transparent mode with a bridge group allows the FTD to inspect and forward traffic as a Layer 2 bridge, keeping the existing IP addressing and routing intact. This is the intended deployment when the firewall must be inserted between segments without becoming a Layer 3 hop.

Answer

Clustering with individual interface IP addresses

Answer

Inline tap mode with a passive interface

Answer

Routed mode with static routes

Question 13

An engineer is deploying a Cisco Secure Firewall Threat Defense device managed by a Firewall Management Center in a high-availability pair. The engineer configures the failover link and state link, verifies interface monitoring, and then applies the configuration. After applying, the standby unit shows as failed and does not synchronize. Which action should the engineer take to resolve the issue?

Accepted Answer

Verify that the failover link interfaces on both units are on the same subnet and are not used for data traffic.. A standby unit marked failed in an FTD high-availability pair usually indicates a problem with the failover link itself. Verifying that the failover interfaces are on a dedicated, correctly addressed subnet and are not carrying data traffic restores hello communication and allows the standby to synchronize and return to a healthy state.

Answer

Disable interface monitoring so the standby stops reporting interface failures.

Answer

Change the standby unit to active mode manually so it begins forwarding traffic.

Answer

Re-register both FTD devices with the FMC using a new registration key.

Question 14

A network administrator is preparing to register a new Cisco Secure Firewall Threat Defense device with a Cisco Secure Firewall Management Center. The device is currently running a supported software version and has network connectivity to the management center. Which action must the administrator take on the FTD device to begin the registration process?

Accepted Answer

Run the configure manager add command and provide the management center hostname and registration key. Registration begins on the FTD CLI with configure manager add, which specifies the management center address and a unique registration key. Once that command is entered, the management center can discover the device and complete the addition using the same key, after which policies can be deployed.

Answer

Import a self-signed certificate from the management center onto the FTD device

Answer

Enable the REST API on the FTD device and create an administrative user for the management center

Answer

Configure a NAT exemption rule on the management center before registration

Question 15

A network security engineer is deploying a Cisco Secure Firewall Threat Defense (FTD) device in a routed mode with two interfaces: inside (10.1.1.1/24) and outside (203.0.113.2/24). The engineer wants to allow inside hosts to reach the internet while ensuring that return traffic is permitted without creating overly permissive rules. The FTD is managed by FMC. Which deployment approach should the engineer use to meet these requirements?

Accepted Answer

Configure a static route for 0.0.0.0/0 pointing to the outside next-hop and create an access control policy that allows traffic from inside to outside with an associated NAT rule for dynamic PAT.. A default route to the outside next-hop enables the FTD to forward internet-bound traffic. An access control policy permits the inside-to-outside flow, and dynamic PAT translates inside addresses to the outside interface, which also handles return traffic. This is the standard routed-mode deployment for internet access with FMC management.

Answer

Configure a static route for 0.0.0.0/0 pointing to the inside next-hop and create an access control policy that allows traffic from outside to inside with a manual NAT rule for static translation.

Answer

Configure a static route for 0.0.0.0/0 pointing to the outside next-hop and create a prefilter policy that allows all IP traffic, then apply a NAT rule for dynamic PAT.

Answer

Configure a static route for 0.0.0.0/0 pointing to the outside next-hop and rely on the implicit allow rule in the access control policy to permit all traffic, then enable NAT exemption for inside hosts.
