Cisco 300-710 Practice Test 26
Question 250
An engineer validates a Cisco Secure Firewall implementation: A regional operations user can view unrelated device groups because inherited management privileges were not tested. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Assume allowing a user to sign in to FMC automatically grants only read-only permissions and no other access.
- Create narrowly scoped management roles and verify device or domain privileges for each operational persona.
- Inspect system time and NTP reachability, DNS lookups, update attempts and health messages in FMC.
- Inspect effective role assignments, domains, device scope and actual attempted view versus edit actions using test accounts.
- Configure supported identity sources and mapping methods with suitable user or group rules and verification of mapping freshness.
Explanation
Correct Answers
B:Appropriate implementation: Create narrowly scoped management roles and verify device or domain privileges for each operational persona. Case details: A regional operations user can view unrelated device groups because inherited management privileges were not tested. Governing behavior: Management console privileges are distinct from firewall data-plane access rules and should enforce task-based least privilege.
D:Direct independent How to verify: Inspect effective role assignments, domains, device scope and actual attempted view versus edit actions using test accounts.
Incorrect Answers
A:Unsafe or unsupported shortcut for this firewall scenario: Assume allowing a user to sign in to FMC automatically grants only read-only permissions and no other access.
C:This alternative describes a different control, FMC DNS NTP update and system health settings, rather than this scenario’s FMC user roles and management authorization: Inspect system time and NTP reachability, DNS lookups, update attempts and health messages in FMC.
E:This alternative describes a different control, Identity-based rule mapping and directory sources, rather than this scenario’s FMC user roles and management authorization: Configure supported identity sources and mapping methods with suitable user or group rules and verification of mapping freshness.
Question 251
A security operations incident describes: A Management Center shows inaccurate event times because its NTP sources are unreachable, obscuring incident sequence. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Create narrowly scoped management roles and verify device or domain privileges for each operational persona.
- Set appropriate management DNS, time synchronization and update connectivity, then verify reachability before changes.
- Configure supported health policies and actionable alerts, correlate symptoms with baseline metrics and perform scoped remediation.
- Assume logged event timestamps remain reliably comparable when management and sensor clocks are unsynchronized.
Explanation
Correct Answer
B:Appropriate implementation: Set appropriate management DNS, time synchronization and update connectivity, then verify reachability before changes.
Incorrect Answers
A:That option would create narrowly scoped management roles and verify device or domain privileges for each operational persona, but it addresses a different concern. Governing behavior: Reliable event correlation and control-plane services depend on correct DNS, clock synchronization and authorized network paths.
C:That option would configure supported health policies and actionable alerts, correlate symptoms with baseline metrics and perform scoped remediation, but it addresses a different concern. Governing behavior: Reliable event correlation and control-plane services depend on correct DNS, clock synchronization and authorized network paths.
D:Unsafe or unsupported shortcut for this firewall scenario: Assume logged event timestamps remain reliably comparable when management and sensor clocks are unsynchronized. It cannot establish the stated security outcome.
Question 252
During a firewall implementation acceptance test: A Management Center shows inaccurate event times because its NTP sources are unreachable, obscuring incident sequence. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
- Network analysis normalizes and interprets protocol traffic before some inspection decisions, and incorrect handling can affect detection fidelity.
- Assume logged event timestamps remain reliably comparable when management and sensor clocks are unsynchronized.
- Intrusion signatures and their policy actions can be tuned with context; disabling broad prevention sacrifices coverage unrelated to one alert.
- Reliable event correlation and control-plane services depend on correct DNS, clock synchronization and authorized network paths.
Explanation
Correct Answer
D:Underlying platform principle: Reliable event correlation and control-plane services depend on correct DNS, clock synchronization and authorized network paths.
Incorrect Answers
A:This alternative describes a different control, Network analysis policy protocol preprocessing, rather than this scenario’s FMC DNS NTP update and system health settings: Network analysis normalizes and interprets protocol traffic before some inspection decisions, and incorrect handling can affect detection fidelity.

C:This alternative describes a different control, Custom intrusion rules and rule-set tuning, rather than this scenario’s FMC DNS NTP update and system health settings: Intrusion signatures and their policy actions can be tuned with context; disabling broad prevention sacrifices coverage unrelated to one alert.

Question 254
A firewall service owner escalates the following: A Management Center shows inaccurate event times because its NTP sources are unreachable, obscuring incident sequence. Which observed result BEST confirms that the change meets the intended security requirement? Select ONE best answer.
- Updated objects reflect approved networks and dependent rules continue to enforce the intended segmentation.
- Events have consistent timestamps and the management platform reaches approved update services without uncontrolled outbound exposure.
- Assume logged event timestamps remain reliably comparable when management and sensor clocks are unsynchronized.

Question 255
An approved maintenance window surfaces this issue: A Management Center shows inaccurate event times because its NTP sources are unreachable, obscuring incident sequence. Which misleading assumption MOST directly causes this issue and must be rejected? Select ONE best answer.
- Assume logged event timestamps remain reliably comparable when management and sensor clocks are unsynchronized.
- Assume security events being visible proves that all sensor resources and management processes are healthy.
