Cisco 300-710 Practice Test 46
Question 450
An engineer validates a Cisco Secure Firewall implementation: A VPN cutover fails after peer certificates rotate and operators edit access-control rules instead of validating IKE authentication. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Inspect IKE and IPsec negotiation state, peer identity, selectors, packet encapsulation counters and return routes.
- Align peer authentication, supported proposals, crypto selectors and routes, and test protected flows in both directions.
- Inspect ordered rules, source and destination zones, network and port conditions and matching connection events.
- Assign management domains and policy ownership deliberately, accounting for inherited settings and shared object scope.
- Assume an IKE SA in an up state proves every subnet selector and data-plane flow is successfully encrypted.
Explanation
Correct Answers
A:Direct independent How to verify: Inspect IKE and IPsec negotiation state, peer identity, selectors, packet encapsulation counters and return routes.
B:Appropriate implementation: Align peer authentication, supported proposals, crypto selectors and routes, and test protected flows in both directions. Case details: A VPN cutover fails after peer certificates rotate and operators edit access-control rules instead of validating IKE authentication. Governing behavior: IKE control-plane establishment is distinct from successful IPsec child security associations and the actual traffic forwarding selectors.
Incorrect Answers
C:That option would inspect ordered rules, source and destination zones, network and port conditions and matching connection events, but it addresses a different concern. Governing behavior: IKE control-plane establishment is distinct from successful IPsec child security associations and the actual traffic forwarding selectors.
D:That option would assign management domains and policy ownership deliberately, accounting for inherited settings and shared object scope, but it addresses a different concern. Governing behavior: IKE control-plane establishment is distinct from successful IPsec child security associations and the actual traffic forwarding selectors.
E:Unsafe or unsupported shortcut for this firewall scenario: Assume an IKE SA in an up state proves every subnet selector and data-plane flow is successfully encrypted.
Question 451
A security operations incident describes: Remote employees authenticate but cannot reach permitted internal resources because the group policy and split-tunnel routes differ from design. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Assume a successful VPN login grants unlimited internal network access and automatically validates endpoint compliance.
- Configure supported remote access VPN or zero-trust network access policies with appropriate identity, entitlement, route and device posture checks.
- Enable appropriate connection logging for the relevant policy and examine the matched rule, action, zones and flow identifiers.
- Assign management domains and policy ownership deliberately, accounting for inherited settings and shared object scope.
Explanation
Correct Answer
B:Appropriate implementation: Configure supported remote access VPN or zero-trust network access policies with appropriate identity, entitlement, route and device posture checks.
Incorrect Answers
A:Unsafe or unsupported shortcut for this firewall scenario: Assume a successful VPN login grants unlimited internal network access and automatically validates endpoint compliance. It cannot establish the stated security outcome.
C: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. Independent evidence: Review user authorization, VPN group policy, client routes, relevant posture integration and application connection results.

Independent evidence: Review user authorization, VPN group policy, client routes, relevant posture integration and application connection results.
Question 452
During a firewall implementation acceptance test: Remote employees authenticate but cannot reach permitted internal resources because the group policy and split-tunnel routes differ from design. Which firewall behavior or technical principle BEST explains the observed condition? Select ONE best answer.
- Assume a successful VPN login grants unlimited internal network access and automatically validates endpoint compliance.
- Encrypted Visibility Engine can infer characteristics of encrypted flows from observable attributes; metadata analytics is distinct from full payload decryption.
- Object reuse improves policy consistency but changes to shared groups propagate to every policy that references them.
- Secure remote access depends on multiple independently configured authorization, endpoint and routing controls, not merely initial authentication.
Explanation
Correct Answer
D:Underlying platform principle: Secure remote access depends on multiple independently configured authorization, endpoint and routing controls, not merely initial authentication.
Incorrect Answers
A:That option would assume a successful VPN login grants unlimited internal network access and automatically validates endpoint compliance, but it addresses a different concern. Approved action: Configure supported remote access VPN or zero-trust network access policies with appropriate identity, entitlement, route and device posture checks.

Question 454
A firewall service owner escalates the following: Remote employees authenticate but cannot reach permitted internal resources because the group policy and split-tunnel routes differ from design. Which observed result BEST confirms that the change meets the intended security requirement? Select ONE best answer.
- Assume a successful VPN login grants unlimited internal network access and automatically validates endpoint compliance.

Question 455
An approved maintenance window surfaces this issue: Remote employees authenticate but cannot reach permitted internal resources because the group policy and split-tunnel routes differ from design. Which misleading assumption MOST directly causes this issue and must be rejected? Select ONE best answer.
- Assume all TCP port 443 traffic is the same application and no application-level identification is required.
