Question 690
A MAC address is spoofed and security operations rely on browser fields as conclusive proof of device ownership. The observed failure is: Using only a user-controlled browser string to grant sensitive access creates spoofing risk. How should the administrator correct and verify this failure?
- The supported recovery is to grant unrestricted network access because a page reports an enterprise device name.
- The supported recovery is to treat any browser User-Agent string as a device certificate.
- The supported recovery is to assume HTTPS encryption always exposes full HTTP headers to a passive sensor.
- The supported recovery is to repair probe data visibility and require stronger evidence before granting privileged policy.
Explanation
Correct Answer
D:HTTP headers may assist endpoint type classification but can be missing or forged. For the specific situation, a MAC address is spoofed and security operations rely on browser fields as conclusive proof of device ownership.
Incorrect Answers
A:Grant unrestricted network access because a page reports an enterprise device name. This action does not repair the identified failure. Using only a user-controlled browser string to grant sensitive access creates spoofing risk. Instead, repair probe data visibility and require stronger evidence before granting privileged policy. For the specific situation, a MAC address is spoofed and security operations rely on browser fields as conclusive proof of device ownership.
B:Treat any browser User-Agent string as a device certificate. This action does not repair the identified failure. Using only a user-controlled browser string to grant sensitive access creates spoofing risk. Instead, repair probe data visibility and require stronger evidence before granting privileged policy. For the specific situation, a MAC address is spoofed and security operations rely on browser fields as conclusive proof of device ownership.

Question 691
A profiling administrator runs active scans on sensitive devices and some embedded clients become unresponsive. Which configuration decision most directly satisfies the requirement?
- Scan every medical device aggressively in production without owner approval.
- Use supported controlled active profiling scans only where authorized and assess device impact and scan reachability.
- Treat a blocked TCP port as proof a service does not exist on the endpoint.
- Use unauthorized broad network scanning to force a trusted device label.
Explanation
Correct Answer
B:Verify the effect through nMAP scan policy, targeted host set, port results, firewall blocks and observed endpoint stability. Active service probing may supplement profiles but has operational and authorization constraints.
Incorrect Answers
A:This does not implement the required control for NMAP profiling active probe and access restrictions. Aggressive unapproved probes can disrupt fragile endpoints or generate misleading classification.
C:Treat a blocked TCP port as proof a service does not exist on the endpoint. This alternative overlooks a required prerequisite or targets the wrong function. Active service probing may supplement profiles but has operational and authorization constraints. The relevant evidence is nMAP scan policy, targeted host set, port results, firewall blocks and observed endpoint stability. For the specific situation, a profiling administrator runs active scans on sensitive devices and some embedded clients become unresponsive.
D:Aggressive unapproved probes can disrupt fragile endpoints or generate misleading classification. Instead the intended policy action is use supported controlled active profiling scans only where authorized and assess device impact and scan reachability.
Question 692
A profiling administrator runs active scans on sensitive devices and some embedded clients become unresponsive. What observations most directly test this network-access condition?

D:This observation cannot verify NMAP profiling active probe and access restrictions. For the specific situation, a profiling administrator runs active scans on sensitive devices and some embedded clients become unresponsive.
Question 693

- Every RADIUS Access-Accept grants unrestricted access to all applications.
Explanation
Correct Answer

Incorrect Answers
B:This generalization is not valid for NMAP profiling active probe and access restrictions. Instead active service probing may supplement profiles but has operational and authorization constraints.
C:This generalization is not valid for NMAP profiling active probe and access restrictions. Verify the actual state using nMAP scan policy, targeted host set, port results, firewall blocks and observed endpoint stability.

Question 694
A profiling administrator runs active scans on sensitive devices and some embedded clients become unresponsive. An operator proposes the following incorrect shortcut: Scan every medical device aggressively in production without owner approval. Which negative consequence BEST explains the shortcut’s flaw?
- Reading the authentication event report caused the original network access outage.
- The only result is an unrelated portal background color change.
- Aggressive unapproved probes can disrupt fragile endpoints or generate misleading classification.

Explanation
Correct Answer
C:The shortcut is unsuitable because active service probing may supplement profiles but has operational and authorization constraints. The supported preventive action is to use supported controlled active profiling scans only where authorized and assess device impact and scan reachability.
