Cisco 300-715 Practice Test 16
Question 150
An LDAP identity source works over cleartext but must meet a secure directory transport policy. The observed failure is: A generic TCP connection to the LDAP port does not prove search authentication or TLS trust is correct. What recovery action restores supported network-access behavior?
- The supported recovery is to treat an unrelated AD OU name as a complete LDAP search filter.
- The supported recovery is to repair the LDAP bind and trust settings then verify user search and permitted access.
- The supported recovery is to store a shared privileged bind credential in a public guest portal.
- The supported recovery is to ignore server identity validation when enabling secure LDAP.
Explanation
Correct Answer
B:LDAP integration depends on a valid service bind and supported secure connection to the directory. Recheck lDAP bind result, DN mapping, server certificate, query logs and identity lookup test.
Incorrect Answers
A:Treat an unrelated AD OU name as a complete LDAP search filter. This action does not repair the identified failure. A generic TCP connection to the LDAP port does not prove search authentication or TLS trust is correct. Instead, repair the LDAP bind and trust settings then verify user search and permitted access. For the specific situation, an LDAP identity source works over cleartext but must meet a secure directory transport policy.
C:Store a shared privileged bind credential in a public guest portal. This action does not repair the identified failure. A generic TCP connection to the LDAP port does not prove search authentication or TLS trust is correct. Instead, repair the LDAP bind and trust settings then verify user search and permitted access. For the specific situation, an LDAP identity source works over cleartext but must meet a secure directory transport policy.
D:Ignore server identity validation when enabling secure LDAP. This action does not repair the identified failure. A generic TCP connection to the LDAP port does not prove search authentication or TLS trust is correct. Instead, repair the LDAP bind and trust settings then verify user search and permitted access. For the specific situation, an LDAP identity source works over cleartext but must meet a secure directory transport policy.
Question 151
An AD controller is unavailable and ISE sends matching 802.1X users to an identity source that contains no such accounts. What action addresses this authenticated network-access scenario?
- Design supported identity source sequence ordering and failure handling consistent with the policy's user types.
- Make every access request bypass password checks on AD timeout.
- Use a guest user store for all privileged machine identities automatically.
- Treat a domain controller ping failure as proof every directory account is invalid.
Explanation
Correct Answer
A:Verify the effect through selected policy rule, identity store lookup sequence, AD availability and audit result. This is the targeted action for Identity source outage versus authentication fallback.
Incorrect Answers
B:Blind fallback to a permissive local database can grant access during a directory outage. This does not implement the required control for Identity source outage versus authentication fallback.
C:Identity source selection changes the authentication path and must not silently broaden allowed identities. This alternative overlooks a required prerequisite or targets the wrong function.
D:Blind fallback to a permissive local database can grant access during a directory outage. Instead the intended policy action is design supported identity source sequence ordering and failure handling consistent with the policy's user types.
Question 152
An AD controller is unavailable and ISE sends matching 802.1X users to an identity source that contains no such accounts. What verification should the engineer use before declaring success?
- A switch interface description without any live AAA request or response.
- An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
- Selected policy rule, identity store lookup sequence, AD availability and audit result.
- A current login screenshot from a completely unrelated ISE deployment.
Explanation
Correct Answer
C:These observations directly establish the result of Identity source outage versus authentication fallback for the described endpoint or network device. Identity source selection changes the authentication path and must not silently broaden allowed identities.
Incorrect Answers
A:A switch interface description without any live AAA request or response. This observation cannot verify Identity source outage versus authentication fallback. Check selected policy rule, identity store lookup sequence, AD availability and audit result. Identity source selection changes the authentication path and must not silently broaden allowed identities.

Question 153
An AD controller is unavailable and ISE sends matching 802.1X users to an identity source that contains no such accounts. Which underlying service behavior supports the proposed solution?
- A captive portal page automatically changes network authorization on every active NAD session without signaling.
- A successful switch port link signal always proves the device identity and policy were verified.
- Identity source selection changes the authentication path and must not silently broaden allowed identities.
- Every RADIUS Access-Accept grants unrestricted access to all applications.
Explanation
Correct Answer
C:The supported implementation is to design supported identity source sequence ordering and failure handling consistent with the policy's user types. This is the governing technical behavior for Identity source outage versus authentication fallback.
Incorrect Answers
A:A captive portal page automatically changes network authorization on every active NAD session without signaling. This generalization is not valid for Identity source outage versus authentication fallback. Instead identity source selection changes the authentication path and must not silently broaden allowed identities.

Question 154
An AD controller is unavailable and ISE sends matching 802.1X users to an identity source that contains no such accounts. An operator proposes the following incorrect shortcut: Make every access request bypass password checks on AD timeout. Why does that proposed shortcut not satisfy the requirement?
- Blind fallback to a permissive local database can grant access during a directory outage.
- Reading the authentication event report caused the original network access outage.
- The only result is an unrelated portal background color change.
- Accurate device accounting automatically created every earlier failed EAP exchange.
Explanation
Correct Answer
A:The shortcut is unsuitable because identity source selection changes the authentication path and must not silently broaden allowed identities. For the specific situation, an AD controller is unavailable and ISE sends matching 802.1X users to an identity source that contains no such accounts.
Incorrect Answers
B:This unrelated assertion does not explain the Identity source outage versus authentication fallback problem. The relevant risk is that blind fallback to a permissive local database can grant access during a directory outage.

D:This unrelated assertion does not explain the Identity source outage versus authentication fallback problem. For the specific situation, an AD controller is unavailable and ISE sends matching 802.1X users to an identity source that contains no such accounts.
