300-710 SNCF Practice Test 13 — 15 Questions

Question 1

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 2

Which FTD command-line tool is primarily used to check interface status and physical link state?

Accepted Answer

show interface. The 'show interface' command provides detailed status on physical link state, speed, and duplex.

Answer

show run

Answer

show service-policy

Answer

show version

Question 3

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 4

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 5

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 6

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 7

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

Accepted Answer

Active/Standby.. FTD supports active/standby and clustering for high availability.

Answer

Active/Active (non-clustered).

Answer

Failover-on-demand.

Answer

Load-Balanced Passive.

Question 8

An administrator is managing Cisco Secure Firewall Threat Defense devices using Cisco Defense Orchestrator (CDO). Which TWO capabilities does CDO provide for firewall deployment and management? (Choose two)

Accepted Answer

Cloud-based policy management, configuration deployment, and security rule cleanup across multiple FTD devices.. CDO is a cloud-based management platform that provides policy management, configuration drift analysis, and bulk management across FTD and other Cisco security devices.

Answer

Deep forensic packet capture analysis equivalent to a full packet broker collector.

Answer

Hardware RMA replacement and physical cabling verification.

Answer

Local hypervisor provisioning for ESXi and KVM virtual machine hypervisors.

Question 9

Which deployment scenario represents the correct use case for deploying a Cisco Secure Firewall Threat Defense in passive NGIPS mode?

Accepted Answer

Out-of-band monitoring of core switch traffic using a SPAN port to detect threats without impacting production latency.. Passive NGIPS mode is used when monitoring traffic out-of-band via a tap or SPAN port without putting the device in the direct path of data flow.

Answer

Acting as the default Layer 3 gateway and DHCP server for guest Wi-Fi users.

Answer

Terminating remote access AnyConnect VPN tunnels for mobile employees.

Answer

Inline inspection of all core data center traffic where blocking malicious packets is mandatory.

Question 10

An engineer is troubleshooting a Cisco Secure Firewall Threat Defense virtual appliance deployed in Microsoft Azure. Connectivity tests show intermittent packet drops. Which THREE troubleshooting steps or configurations should be verified in Azure and FTDv? (Choose three)

Accepted Answer

Check Azure User Defined Routes (UDRs) to ensure packet steering to the correct firewall internal/external ENIs is accurate.. Azure deployments require checking User Defined Routes (UDRs), Source NAT (SNAT) configurations for load balancers, and Azure NSG (Network Security Group) rules.

Answer

Verify that physical fiber optic bypass modules are firmly clicked into the Azure hypervisor chassis.

Answer

Ensure the FTDv is running in transparent mode with BVI clustering enabled across multiple Azure regions.

Question 11

An engineer is configuring NGIPS inline sets on a Cisco Secure Firewall Threat Defense deployment. Which THREE configuration options or behaviors are associated with inline sets? (Choose three)

Accepted Answer

Snort Bypass can be configured to pass traffic uninspected if the inspection engine is overloaded.. Inline sets inspect traffic passing between paired interfaces, support Snort bypass options, and can utilize tap or inline normalization features.

Answer

Inline sets automatically function as dynamic OSPF routers for neighboring switches.

Answer

Inline sets require every participating interface to have a unique Layer 3 IP address.

Question 12

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 13

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 14

An enterprise is deploying a high-availability cluster of Cisco Secure Firewall Threat Defense devices to scale performance. Which requirement must be met regarding the physical switch infrastructure connecting the cluster nodes?

Accepted Answer

Connections between the switches and cluster nodes must use Port Channels (EtherChannels) to aggregate bandwidth and ensure proper traffic distribution.. Firewall clustering requires specific switch features such as EtherChannel (Port Channels) and often requires specific load-balancing algorithms to distribute traffic across cluster members evenly.

Answer

Switches must be configured with Spanning Tree Protocol (STP) disabled globally to prevent cluster split-brain.

Answer

The switches must run Cisco StackWise Virtual and be managed by the firewall cluster master node.

Answer

Routing protocols must be disabled on all switch interfaces connected to the cluster control link (CCL).

Question 15

An engineer is deploying an NGIPS inline set across two physical interfaces. To prevent network disruption during maintenance, the engineer needs to ensure that if the firewall loses power or experiences a kernel panic, traffic can still traverse the physical link. Which hardware feature must the interfaces support?

Accepted Answer

Hardware bypass capability (fail-open). Optical or copper bypass capability (hardware fail-open/fail-close bypass caps) allows traffic to pass physically through the ports when power is lost or the system crashes.

Answer

Unidirectional Link Detection (UDLD)

Answer

Spanning Tree PortFast BPDU filtering

Answer

Dynamic ARP Inspection (DAI)
