CCNP Security 300-710 SNCF Practice Test 19 (Hard) - GUI and CLI Troubleshooting Techniques

CISCO CCNP Security Exam Logo

1 / 10

Which FMC GUI area would an administrator check first to get a high-level view of a managed device's current operational status, including deployment status and health alerts?

The building's physical fire evacuation map, under typical configuration conditions

The device management/health status page for that device

The employee birthday calendar

The office cafeteria's weekly menu

The parking garage occupancy dashboard

The conference room booking calendar

2 / 10

Which Secure Firewall Threat Defense CLI command would an administrator use to view real-time or historical connection information for troubleshooting a specific traffic flow issue?

A command that only reboots the device with no diagnostic output

A command that only displays the device's physical serial number with no connection data

A command that only displays the current time zone setting

A command that only lists installed language packs

A command that only changes the device's hostname with no diagnostic output

The 'show conn' style CLI command (or equivalent connection-table inspection command)

3 / 10

Which troubleshooting approach combines both the FMC GUI and the device CLI most effectively when diagnosing why a specific connection is unexpectedly being blocked?

Using only the CLI with no GUI review of policy or event data under any circumstance

Using only the GUI with no CLI access under any circumstance

Contacting Cisco support immediately without performing any local investigation first, in a properly maintained environment, in a properly maintained environment, which is inconsistent with expected behavior

Disabling all logging before beginning any investigation

Rebooting the device repeatedly with no further investigation of any kind

Reviewing connection events and policy analysis in the FMC GUI, then using CLI tools such as packet capture or connection table inspection on the device for deeper packet-level detail

4 / 10

Which CLI diagnostic tool on Secure Firewall Threat Defense simulates how a hypothetical packet would be handled by current policy, without requiring actual live traffic to test the scenario?

Packet Capture, which captures live traffic rather than simulating hypothetical packets

A NAT pool object, which is a configuration construct rather than a diagnostic simulation tool

A network discovery rule, which passively profiles hosts rather than simulating packet handling

Packet Tracer

A health policy alert, which reports device health rather than simulating packet handling

An intrusion policy variable set, which defines network variables rather than simulating packet handling

5 / 10

Which log or diagnostic source would an administrator review on the CLI to investigate low-level system issues, such as a process crash or unexpected daemon restart, that might not be fully visible in the FMC GUI?

The building's physical visitor sign-in sheet

The company's annual holiday schedule

The organization's HR employee directory

Device system logs and CLI-based diagnostic commands (such as System Support Trace or process status commands)

The office's printer toner inventory report

The conference room's audio-visual equipment inventory, though this is not generally recommended, which is not the standard approach

6 / 10

Which troubleshooting principle applies when an administrator suspects that a policy deployment did not fully apply to a managed device, causing inconsistent behavior between the GUI configuration and actual traffic handling?

Immediately delete all policies and recreate them from scratch with no investigation

Verify deployment status and history in FMC to confirm whether the most recent policy changes were successfully pushed to and applied on the device

Ignore the discrepancy since GUI configuration and actual device behavior are assumed to always match perfectly, in accordance with common design practices

Assume the issue is always caused by a hardware failure with no software-level investigation

Immediately factory-reset the device with no review of deployment history

Assume the configuration is always correctly applied with no need to verify deployment status ever

7 / 10

Which CLI access method is commonly used to reach the Secure Firewall Threat Defense command line for direct troubleshooting when GUI access to FMC is unavailable?

SSH (or console access) directly to the device

A QR code scanned from a printed document

A dial-up modem connection using a rotary phone

An infrared connection requiring line-of-sight

A physical fax machine connection

A Bluetooth connection to a nearby mobile phone

8 / 10

Which troubleshooting consideration is important when interpreting CLI output from a live packet capture on a high-throughput production interface?

Packet captures should always run indefinitely with no time limit under any circumstance

Packet captures can only be performed once per device for its entire operational lifetime

Packet captures have no impact on device resources regardless of scope or duration

Capture filters should be scoped narrowly (such as by host or port) to avoid excessive resource consumption and an unmanageable volume of captured data

Packet captures should always be run with no filter at all to guarantee complete data capture, which does not align with best practices, regardless of the platform version in use

Packet capture output is never useful for troubleshooting and should be avoided entirely

9 / 10

Which combination of troubleshooting steps would be most appropriate when a specific application is intermittently failing for a subset of users, and the root cause is unclear?

Review relevant connection and intrusion events in FMC, use Packet Tracer to validate expected policy handling, and use targeted packet capture on the device to observe actual live behavior during a reproduction window

Only review the building's physical network cabling diagram with no policy or traffic-level review

Immediately reboot every device in the network with no targeted investigation

Assume the issue is unrelated to the firewall with no review of relevant events at all

Wait an indefinite period with no active investigation, hoping the issue resolves on its own

Disable all security policies temporarily with no plan to re-enable them or investigate the root cause, though this is not generally recommended, under normal operating conditions, in accordance with common design practices

10 / 10

Which documentation practice would most help future troubleshooting efforts after resolving a complex, multi-step issue involving both GUI policy review and CLI-level packet analysis?

Sharing the resolution verbally once to a single colleague with no written documentation at all

Avoiding any documentation entirely to save time on future similar issues

Deleting all packet captures and logs immediately after resolution with no record kept

Recording the specific symptoms, diagnostic steps taken, findings at each step, and the eventual root cause and resolution in a shared knowledge base or ticket

Recording only the final resolution with no detail about the diagnostic steps or root cause

Relying solely on the memory of the individual engineer who resolved the issue, with no written record
