Cisco 300-710 Practice Test 34
Question 330
An engineer validates a Cisco Secure Firewall implementation: A security team blocks a generic web category and inadvertently disrupts an approved business portal because exceptions were not staged. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Inspect system time and NTP reachability, DNS lookups, update attempts and health messages in FMC.
- Choose supported URL and application matching with explicit TLS decryption or metadata limitations and test exception scope.
- Assume every HTTPS session exposes its complete URL path to any firewall policy without TLS decryption.
- Inspect effective SSL or TLS inspection settings, application identification and URL event fields for test sessions.
- Enable and tune supported encrypted-traffic analysis using available metadata, then corroborate detections without claiming decrypted content.
Explanation
Correct Answers
B:Appropriate implementation: Choose supported URL and application matching with explicit TLS decryption or metadata limitations and test exception scope. Case details: A security team blocks a generic web category and inadvertently disrupts an approved business portal because exceptions were not staged. Governing behavior: Encrypted traffic may expose less application detail than decrypted traffic, while URL category and application detectors use different identification inputs.
D:Direct independent How to verify: Inspect effective SSL or TLS inspection settings, application identification and URL event fields for test sessions.
Incorrect Answers
A:That option would inspect system time and NTP reachability, DNS lookups, update attempts and health messages in FMC, but it addresses a different concern. Governing behavior: Encrypted traffic may expose less application detail than decrypted traffic, while URL category and application detectors use different identification inputs.
C:Unsafe or unsupported shortcut for this firewall scenario: Assume every HTTPS session exposes its complete URL path to any firewall policy without TLS decryption.
E:That option would enable and tune supported encrypted-traffic analysis using available metadata, then corroborate detections without claiming decrypted content, but it addresses a different concern. Governing behavior: Encrypted traffic may expose less application detail than decrypted traffic, while URL category and application detectors use different identification inputs.
Question 331
A security operations incident describes: A discovery policy produces few asset records because its monitored networks exclude the active data center segment. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Enable appropriate connection logging for the relevant policy and examine the matched rule, action, zones and flow identifiers.
- Assume enabling host discovery makes every unreachable or unobserved endpoint immediately and perfectly inventoried.
- Configure appropriate network discovery scope and review observed host attributes, data age and privacy boundaries.
- Use supported application identification or custom detector methods based on recognizable traffic attributes and validate on controlled samples.
Explanation
Correct Answer
C:Appropriate implementation: Configure appropriate network discovery scope and review observed host attributes, data age and privacy boundaries.
Incorrect Answers
A:That option would enable appropriate connection logging for the relevant policy and examine the matched rule, action, zones and flow identifiers, but it addresses a different concern. Governing behavior: Network discovery can infer assets from observed traffic but only for monitored coverage and with potentially incomplete or stale attributes.
B:That option would assume enabling host discovery makes every unreachable or unobserved endpoint immediately and perfectly inventoried, but it addresses a different concern. Governing behavior: Network discovery can infer assets from observed traffic but only for monitored coverage and with potentially incomplete or stale attributes.
D:That option would use supported application identification or custom detector methods based on recognizable traffic attributes and validate on controlled samples, but it addresses a different concern. Governing behavior: Network discovery can infer assets from observed traffic but only for monitored coverage and with potentially incomplete or stale attributes.
Question 332
During a firewall implementation acceptance test: A discovery policy produces few asset records because its monitored networks exclude the active data center segment. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
- Assume enabling host discovery makes every unreachable or unobserved endpoint immediately and perfectly inventoried.
- Network discovery can infer assets from observed traffic but only for monitored coverage and with potentially incomplete or stale attributes.
- Correlation detects relationships among observed events when required fields and timing overlap, rather than inferring every attack from one event.
- Certificate trust validates issuer, validity and identity; installing any certificate file does not automatically establish peer trust.
Explanation
Correct Answer
B:Underlying platform principle: Network discovery can infer assets from observed traffic but only for monitored coverage and with potentially incomplete or stale attributes.
Incorrect Answers
A:Unsafe or unsupported shortcut for this firewall scenario: Assume enabling host discovery makes every unreachable or unobserved endpoint immediately and perfectly inventoried. It cannot establish the stated security outcome.
C:This alternative describes a different control, Correlation policies for related security events, rather than this scenario’s Network discovery and host profiling scope: Correlation detects relationships among observed events when required fields and timing overlap, rather than inferring every attack from one event.
D:This alternative describes a different control, Device certificates management and trust chains, rather than this scenario’s Network discovery and host profiling scope: Certificate trust validates issuer, validity and identity; installing any certificate file does not automatically establish peer trust.

Question 335
An approved maintenance window surfaces this issue: A discovery policy produces few asset records because its monitored networks exclude the active data center segment. Which misleading assumption MOST directly causes this issue and must be rejected? Select ONE best answer.
- Assume a certificate is trusted merely because it was imported into a firewall management interface.
