Cisco 300-715 Practice Test 54
Question 530
A visitor captive portal works but their post-login ACL inadvertently blocks DNS and public web browsing. The observed failure is: An unrestricted postlogin ACL can let visitors reach internal business systems. How should the administrator correct and verify this failure?
- The supported recovery is to disable all DNS service to avoid internal name exposure without a functioning replacement.
- The supported recovery is to give every guest the same role as a domain administrator.
- The supported recovery is to correct guest network segmentation and prove public access and internal denial.
- The supported recovery is to assume guest portal acceptance alone enforces routing firewall rules.
Explanation
Correct Answer
C:This restores the intended operational behavior for Guest access DNS HTTP and restricted Internet policy. For the specific situation, a visitor captive portal works but their post-login ACL inadvertently blocks DNS and public web browsing.
Incorrect Answers
A:Disable all DNS service to avoid internal name exposure without a functioning replacement. This action does not repair the identified failure. An unrestricted postlogin ACL can let visitors reach internal business systems. Instead, correct guest network segmentation and prove public access and internal denial. For the specific situation, a visitor captive portal works but their post-login ACL inadvertently blocks DNS and public web browsing.
B:Give every guest the same role as a domain administrator. This action does not repair the identified failure. An unrestricted postlogin ACL can let visitors reach internal business systems.

Question 531
Security operations cannot link a visitor's wireless login to the sponsor and time of registration. Which configuration decision most directly satisfies the requirement?
- Use one perpetual lobby password as unique identity evidence for every visitor.
- Use uniquely traceable guest accounts and preserve sponsor, session and authorization audit records.
- Delete sponsor logs as soon as a guest account is activated.
- Assume an IP geolocation label definitively identifies the human visitor.
Explanation
Correct Answer
B:Verify the effect through guest account identity, sponsor, device MAC, authentication timeline, RADIUS accounting and expiry. For the specific situation, security operations cannot link a visitor's wireless login to the sponsor and time of registration.
Incorrect Answers
A:Use one perpetual lobby password as unique identity evidence for every visitor. This does not implement the required control for Guest portal audit records and accountable access. Shared untracked visitor credentials make post-incident attribution unreliable. Use the supported approach: use uniquely traceable guest accounts and preserve sponsor, session and authorization audit records. For the specific situation, security operations cannot link a visitor's wireless login to the sponsor and time of registration.
C:Attributable guest access depends on distinct account ownership and retained session evidence. For the specific situation, security operations cannot link a visitor's wireless login to the sponsor and time of registration.
D:Assume an IP geolocation label definitively identifies the human visitor. This leaves the original requirement unresolved. Shared untracked visitor credentials make post-incident attribution unreliable. Instead the intended policy action is use uniquely traceable guest accounts and preserve sponsor, session and authorization audit records. For the specific situation, security operations cannot link a visitor's wireless login to the sponsor and time of registration.
