Cisco 300-710 Practice Test 41
Question 400
A Secure Firewall deployment change request reports: A responder disables an entire inspection policy to avoid one noisy rule without checking a targeted suppression or tuning option. Which THREE complementary elements form the corrective action, diagnostic proof and successful acceptance outcome? Select THREE answers.
- Inspect ordered rules, source and destination zones, network and port conditions and matching connection events.
- Assume suppressing or disabling all intrusion events is the only way to handle one noisy signature.
- Review supported Snort intrusion rule conditions and select narrowly scoped tuning, suppression or rule-state changes with tests.
- Inspect intrusion rule identity, traffic payload sample, triggered variables and event distribution before and after tuning.
- Known benign test flows stop generating the false alert while genuine matching malicious patterns remain detectable.
- Define and review reusable network or host objects with scoped references and test impacted policies before edits.
Explanation
Correct Answers
C:Appropriate implementation: Review supported Snort intrusion rule conditions and select narrowly scoped tuning, suppression or rule-state changes with tests. Case details: A responder disables an entire inspection policy to avoid one noisy rule without checking a targeted suppression or tuning option. Governing behavior: Intrusion signatures and their policy actions can be tuned with context; disabling broad prevention sacrifices coverage unrelated to one alert.
D:Direct independent How to verify: Inspect intrusion rule identity, traffic payload sample, triggered variables and event distribution before and after tuning.
E:Required acceptance evidence: Known benign test flows stop generating the false alert while genuine matching malicious patterns remain detectable. Case details: A responder disables an entire inspection policy to avoid one noisy rule without checking a targeted suppression or tuning option. Governing behavior: Intrusion signatures and their policy actions can be tuned with context; disabling broad prevention sacrifices coverage unrelated to one alert.
Incorrect Answers
A:This alternative describes a different control, Access control policy ordering and default behavior, rather than this scenario’s Custom intrusion rules and rule-set tuning: Inspect ordered rules, source and destination zones, network and port conditions and matching connection events.
B:Unsafe or unsupported shortcut for this firewall scenario: Assume suppressing or disabling all intrusion events is the only way to handle one noisy signature.
F:That option would define and review reusable network or host objects with scoped references and test impacted policies before edits, but it addresses a different concern. Governing behavior: Intrusion signatures and their policy actions can be tuned with context; disabling broad prevention sacrifices coverage unrelated to one alert.
Question 401
An FMC policy and traffic review discovers: A managed firewall presents an expired management certificate and secure registration or API access fails. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Define appropriately scoped correlation rules with relevant event inputs, thresholding and response evaluation.
- Choose supported URL and application matching with explicit TLS decryption or metadata limitations and test exception scope.
- Assume a certificate is trusted merely because it was imported into a firewall management interface.
- Install a supported identity certificate with correct hostname and issuing trust chain, then verify secure management connections.
Explanation
Correct Answer
D:Appropriate implementation: Install a supported identity certificate with correct hostname and issuing trust chain, then verify secure management connections.
Incorrect Answers
A:This alternative describes a different control, Correlation policies for related security events, rather than this scenario’s Device certificates management and trust chains: Define appropriately scoped correlation rules with relevant event inputs, thresholding and response evaluation.
B:That option would choose supported URL and application matching with explicit TLS decryption or metadata limitations and test exception scope, but it addresses a different concern. Governing behavior: Certificate trust validates issuer, validity and identity; installing any certificate file does not automatically establish peer trust.
C:Unsafe or unsupported shortcut for this firewall scenario: Assume a certificate is trusted merely because it was imported into a firewall management interface. It cannot establish the stated security outcome.
Question 402
An engineer validates a Cisco Secure Firewall implementation: A managed firewall presents an expired management certificate and secure registration or API access fails. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
- Assume a certificate is trusted merely because it was imported into a firewall management interface.
- Multidomain management enables delegated administration, but inheritance and shared definitions can affect multiple managed areas.
- Certificate trust validates issuer, validity and identity; installing any certificate file does not automatically establish peer trust.
- Correlation detects relationships among observed events when required fields and timing overlap, rather than inferring every attack from one event.
Explanation
Correct Answer
C:Underlying platform principle: Certificate trust validates issuer, validity and identity; installing any certificate file does not automatically establish peer trust.
Incorrect Answers
A:Unsafe or unsupported shortcut for this firewall scenario: Assume a certificate is trusted merely because it was imported into a firewall management interface. It cannot establish the stated security outcome.

- Authorized management clients complete verified TLS sessions with valid nonexpired trusted identities.
- Current authorized indicators are applied with reversible controls and legitimate destinations are not broadly blocked by unreviewed stale data.
- Investigators can attribute the denied or permitted session to the correct deployed rule without logging unnecessary sensitive data.
- Assume a certificate is trusted merely because it was imported into a firewall management interface.
Explanation
Correct Answer
A:Required acceptance evidence: Authorized management clients complete verified TLS sessions with valid nonexpired trusted identities.

Question 405
A CCNP Security practice scenario presents this condition: A managed firewall presents an expired management certificate and secure registration or API access fails. 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.
- Assume every HTTPS session exposes its complete URL path to any firewall policy without TLS decryption.
