Cisco 300-715 Practice Test 69
Question 680
ISE SNMP probe receives timeouts after access switches move to a restricted management VRF. The observed failure is: An unreachable SNMP agent leaves physical attachment evidence incomplete. Which controlled recovery BEST restores the intended state?
- The supported recovery is to restore protected SNMP connectivity and validate MAC-to-port mapping against the access switch.
- The supported recovery is to use an old topology diagram instead of checking the current forwarding table.
- The supported recovery is to expose SNMP community strings in public guest-portal HTML.
- The supported recovery is to assume any ICMP ping proves SNMP inventory authorization works.
Explanation
Correct Answer
A:SNMP probes can enrich endpoint context using network device data when permissions and routes work. Recheck sNMP query result, interface table, MAC address table, access source and corresponding endpoint record.
Incorrect Answers
B:Use an old topology diagram instead of checking the current forwarding table. This action does not repair the identified failure. An unreachable SNMP agent leaves physical attachment evidence incomplete. Instead, restore protected SNMP connectivity and validate MAC-to-port mapping against the access switch. For the specific situation, iSE SNMP probe receives timeouts after access switches move to a restricted management VRF.
C:Expose SNMP community strings in public guest-portal HTML. This action does not repair the identified failure. An unreachable SNMP agent leaves physical attachment evidence incomplete. Instead, restore protected SNMP connectivity and validate MAC-to-port mapping against the access switch. For the specific situation, iSE SNMP probe receives timeouts after access switches move to a restricted management VRF.
D:Assume any ICMP ping proves SNMP inventory authorization works. This action does not repair the identified failure. An unreachable SNMP agent leaves physical attachment evidence incomplete. Instead, restore protected SNMP connectivity and validate MAC-to-port mapping against the access switch. For the specific situation, iSE SNMP probe receives timeouts after access switches move to a restricted management VRF.
Question 681
An unmanaged tablet enters a portal and ISE does not capture its HTTP User-Agent for endpoint classification. What is the BEST supported ISE implementation or corrective action?
- Treat any browser User-Agent string as a device certificate.
- Assume HTTPS encryption always exposes full HTTP headers to a passive sensor.
- Capture supported HTTP probe metadata and treat user-agent fingerprints as supplemental evidence.
- Grant unrestricted network access because a page reports an enterprise device name.
Explanation
Correct Answer
C:Verify the effect through observed HTTP request, User-Agent header, portal reachability, profiler attribute and match. For the specific situation, an unmanaged tablet enters a portal and ISE does not capture its HTTP User-Agent for endpoint classification.
Incorrect Answers
A:This does not implement the required control for HTTP probe user-agent and browser fingerprint limitations. Using only a user-controlled browser string to grant sensitive access creates spoofing risk.
B:Assume HTTPS encryption always exposes full HTTP headers to a passive sensor. This alternative overlooks a required prerequisite or targets the wrong function. HTTP headers may assist endpoint type classification but can be missing or forged. The relevant evidence is observed HTTP request, User-Agent header, portal reachability, profiler attribute and match. For the specific situation, an unmanaged tablet enters a portal and ISE does not capture its HTTP User-Agent for endpoint classification.
D:Using only a user-controlled browser string to grant sensitive access creates spoofing risk. For the specific situation, an unmanaged tablet enters a portal and ISE does not capture its HTTP User-Agent for endpoint classification.
Question 682
An unmanaged tablet enters a portal and ISE does not capture its HTTP User-Agent for endpoint classification. Which evidence BEST verifies the intended operational outcome?

- A current login screenshot from a completely unrelated ISE deployment.
- A browser theme label without a current authorization trace.

- All Cisco ISE administration and policy personas perform exactly the same service.
- A policy display name alone is the complete source of enforcement state.

C:This generalization is not valid for HTTP probe user-agent and browser fingerprint limitations. For the specific situation, an unmanaged tablet enters a portal and ISE does not capture its HTTP User-Agent for endpoint classification.
D:This generalization is not valid for HTTP probe user-agent and browser fingerprint limitations. Verify the actual state using observed HTTP request, User-Agent header, portal reachability, profiler attribute and match.
Question 684
An unmanaged tablet enters a portal and ISE does not capture its HTTP User-Agent for endpoint classification. An operator proposes the following incorrect shortcut: Treat any browser User-Agent string as a device certificate. What material risk or failure follows from that shortcut?
- A justified least-privilege ACL caused every unrelated network authentication fault.
- A correctly recorded TACACS command audit caused the preceding security violation.
- Using only a user-controlled browser string to grant sensitive access creates spoofing risk.
- Reading the authentication event report caused the original network access outage.
Explanation
Correct Answer
C:The shortcut is unsuitable because hTTP headers may assist endpoint type classification but can be missing or forged. For the specific situation, an unmanaged tablet enters a portal and ISE does not capture its HTTP User-Agent for endpoint classification.
