Cisco 300-710 Practice Test 28
Question 270
A firewall service owner escalates the following: A security administrator believes a child domain has complete independent ownership of a globally shared object and breaks another tenant. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Assume assigning a device to a child domain automatically isolates every global object from parent policies.
- Inspect selected network analysis policy, protocol diagnostics, event evidence and controlled traffic samples.
- Assign management domains and policy ownership deliberately, accounting for inherited settings and shared object scope.
- Inspect selected management domain, object ownership, inherited policies and test permissions in the intended child domain.
- Create narrowly scoped management roles and verify device or domain privileges for each operational persona.
Explanation
Correct Answers
C:Appropriate implementation: Assign management domains and policy ownership deliberately, accounting for inherited settings and shared object scope. Case details: A security administrator believes a child domain has complete independent ownership of a globally shared object and breaks another tenant. Governing behavior: Multidomain management enables delegated administration, but inheritance and shared definitions can affect multiple managed areas.
D:Direct independent How to verify: Inspect selected management domain, object ownership, inherited policies and test permissions in the intended child domain.
Incorrect Answers
A:Unsafe or unsupported shortcut for this firewall scenario: Assume assigning a device to a child domain automatically isolates every global object from parent policies.
B:This alternative describes a different control, Network analysis policy protocol preprocessing, rather than this scenario’s FMC domain hierarchy and configuration ownership: Inspect selected network analysis policy, protocol diagnostics, event evidence and controlled traffic samples.
E: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: Multidomain management enables delegated administration, but inheritance and shared definitions can affect multiple managed areas.
Question 271
An approved maintenance window surfaces this issue: A new block rule never applies because a broader allow rule above it already matches a sensitive application flow. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Choose supported URL and application matching with explicit TLS decryption or metadata limitations and test exception scope.
- Place sufficiently specific access-control rules in intended evaluation order and set a documented default action.
- Assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules.
- Define and review reusable network or host objects with scoped references and test impacted policies before edits.
Explanation
Correct Answer
B:Appropriate implementation: Place sufficiently specific access-control rules in intended evaluation order and set a documented default action.
Incorrect Answers
A: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: Access-control evaluation follows configured rule order and matching conditions, and a broad earlier match can make later rules unreachable.
C:That option would assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules, but it addresses a different concern. Governing behavior: Access-control evaluation follows configured rule order and matching conditions, and a broad earlier match can make later rules unreachable.
D: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: Access-control evaluation follows configured rule order and matching conditions, and a broad earlier match can make later rules unreachable.
Question 272
A Secure Firewall deployment change request reports: A new block rule never applies because a broader allow rule above it already matches a sensitive application flow. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
- A service port does not by itself prove the application protocol; application detectors use traffic characteristics with visibility constraints.
- Assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules.
- Multidomain management enables delegated administration, but inheritance and shared definitions can affect multiple managed areas.
- Access-control evaluation follows configured rule order and matching conditions, and a broad earlier match can make later rules unreachable.
Explanation
Correct Answer
D:Underlying platform principle: Access-control evaluation follows configured rule order and matching conditions, and a broad earlier match can make later rules unreachable.
Incorrect Answers
A:This alternative describes a different control, Application detector tuning and custom signatures, rather than this scenario’s Access control policy ordering and default behavior: A service port does not by itself prove the application protocol; application detectors use traffic characteristics with visibility constraints.
B:That option would assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules, but it addresses a different concern. Acceptance criterion: A representative allowed flow matches its intended rule while the restricted test flow is denied by the correct policy.
C:This alternative describes a different control, FMC domain hierarchy and configuration ownership, rather than this scenario’s Access control policy ordering and default behavior: Multidomain management enables delegated administration, but inheritance and shared definitions can affect multiple managed areas.
Question 273
An FMC policy and traffic review discovers: A new block rule never applies because a broader allow rule above it already matches a sensitive application flow. Which specific evidence is MOST useful to confirm the real root cause? Select ONE best answer.
- Inspect selected network analysis policy, protocol diagnostics, event evidence and controlled traffic samples.
- Inspect ordered rules, source and destination zones, network and port conditions and matching connection events.
- Assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules.
- Inspect EVE policy, TLS handshake metadata, connection correlation and independent endpoint or intrusion evidence.
Explanation
Correct Answer
B:Direct independent verification: Inspect ordered rules, source and destination zones, network and port conditions and matching connection events.
Incorrect Answers
A:This alternative describes a different control, Network analysis policy protocol preprocessing, rather than this scenario’s Access control policy ordering and default behavior: Inspect selected network analysis policy, protocol diagnostics, event evidence and controlled traffic samples.
C:Unsafe or unsupported shortcut for this firewall scenario: Assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules. It cannot establish the stated security outcome.
D:That option would inspect EVE policy, TLS handshake metadata, connection correlation and independent endpoint or intrusion evidence, but it addresses a different concern. Governing behavior: Access-control evaluation follows configured rule order and matching conditions, and a broad earlier match can make later rules unreachable.
Question 274
An engineer validates a Cisco Secure Firewall implementation: A new block rule never applies because a broader allow rule above it already matches a sensitive application flow. Which observed result BEST confirms that the change meets the intended security requirement? Select ONE best answer.
- Assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules.
- Investigators can attribute the denied or permitted session to the correct deployed rule without logging unnecessary sensitive data.
- A representative allowed flow matches its intended rule while the restricted test flow is denied by the correct policy.
- An analyst can review authorized events without modifying policies or viewing unrelated restricted infrastructure.
Explanation
Correct Answer
C:Required acceptance evidence: A representative allowed flow matches its intended rule while the restricted test flow is denied by the correct policy.
Incorrect Answers
A:Unsafe or unsupported shortcut for this firewall scenario: Assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules. It cannot establish the stated security outcome.
B:This alternative describes a different control, Access policy rule logging and event attribution, rather than this scenario’s Access control policy ordering and default behavior: Investigators can attribute the denied or permitted session to the correct deployed rule without logging unnecessary sensitive data.
D:This alternative describes a different control, FMC user roles and management authorization, rather than this scenario’s Access control policy ordering and default behavior: An analyst can review authorized events without modifying policies or viewing unrelated restricted infrastructure.
Question 275
A security operations incident describes: A new block rule never applies because a broader allow rule above it already matches a sensitive application flow. Which misleading assumption MOST directly causes this issue and must be rejected? Select ONE best answer.
- Assume a classification of encrypted traffic means the firewall has read and verified all plaintext application contents.
- Assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules.
- Assume access-control port rules alone replace network analysis and protocol normalization for intrusion detection.
- Assume every HTTPS session exposes its complete URL path to any firewall policy without TLS decryption.
Explanation
Correct Answer
B:Reject the scenario-specific unsafe assumption: Assume placing a specific block rule anywhere in an ordered access list overrides earlier matching allow rules. The stated shortcut conflicts with the intended control and its documented verification.
Incorrect Answers
A:That option would assume a classification of encrypted traffic means the firewall has read and verified all plaintext application contents, but it addresses a different concern. Governing behavior: Access-control evaluation follows configured rule order and matching conditions, and a broad earlier match can make later rules unreachable.
C:That option would assume access-control port rules alone replace network analysis and protocol normalization for intrusion detection, but it addresses a different concern. Governing behavior: Access-control evaluation follows configured rule order and matching conditions, and a broad earlier match can make later rules unreachable.
