20+ practice questions focused on Management And Troubleshooting — one of the most tested topics on the Cisco Securing Networks with Cisco Firewalls (300-710 SNCF, CCNP Security) (300-710 SNCF) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Management And Troubleshooting PracticeAn administrator successfully restores an FMC backup onto a freshly deployed FMC virtual appliance of the exact same software version. However, after the restore completes, all managed FTD devices show a status of 'Offline' or 'Config Apply Failed'. What is the most likely root cause and correct resolution?
Explanation: When an FMC backup is restored onto a new FMC appliance, the new FMC generates its own system UUID and Internal Certificate Authority (CA) keys, which differ from the original FMC's. FTD devices trust the original FMC's CA and UUID, so after restore they cannot re-establish the sftunnel trust relationship and show as Offline or Config Apply Failed. The correct resolution is to re-register each FTD with the new FMC using fresh registration keys.
An administrator notices that the Firepower Management Center (FMC) health monitor shows a critical warning regarding high disk utilization on the /var partition. Which built-in utility or action should the administrator perform first to safely free up disk space without disrupting critical database integrity?
Explanation: The FMC health monitor flags /var disk pressure primarily because event data, correlation logs, and stored packet captures accumulate there. The supported, non-disruptive remediation is to use the FMC GUI to delete unneeded packet captures and prune older correlation/event data (System > Health > Monitor, plus Analysis > Correlation > Audit Log or the event pruning settings). This frees space while preserving the database schema and integrity, unlike manual filesystem surgery.
An FTD device managed by FMC is experiencing high CPU utilization attributed to the Snort inspection engine. The administrator wants to identify which specific intrusion rules or access control rules are consuming the most resources. Which tool or report should the administrator use?
Explanation: The Intrusion Performance dashboard in FMC provides detailed statistics on Snort inspection performance, including top rules by packet count, byte count, and CPU usage. Additionally, the FTD CLI command 'system support diagnostic-cli' followed by 'show perfstats' gives real-time performance data for the Snort engine. Together, these tools allow the administrator to identify which specific intrusion rules or access control rules are consuming the most resources.
An engineer needs to troubleshoot an intermittent connectivity issue between a secured zone and the internet through a Firepower Threat Defense (FTD) managed by FMC. The engineer wants to capture traffic hitting a specific Access Control rule without overwhelming the system. Which packet capture configuration is most appropriate?
Explanation: FMC's advanced packet capture feature (Devices > Device Management > Packet Capture) allows you to define a capture with specific ingress interfaces, IP/port filters, and buffer settings, which limits the capture to only the traffic of interest. This targeted approach avoids overwhelming the FTD's CPU and disk while still capturing packets that hit the specific Access Control rule being troubleshot. Promiscuous mode is not strictly required for FTD captures but the option is available; the key is the filtering and interface scoping.
An administrator is preparing to upgrade a high-availability (HA) pair of Firepower Threat Defense devices managed by an FMC. Before initiating the upgrade task via the FMC upgrade tool, which preliminary action is mandatory to ensure a seamless process and prevent split-brain conditions?
Explanation: Before upgrading an FTD HA pair via FMC, the mandatory preliminary step is to run the software pre-upgrade checker package on the FTD units through the FMC System > Updates interface. This checker validates readiness by identifying blocking dependencies, insufficient disk space, and other conditions that could cause the upgrade to fail or cause HA split-brain. It is a required step in the FMC upgrade workflow.
