Question 1140

An administrator migrates from an old TACACS server and forgets to match shared secrets on routers and ISE. The observed failure is: A correct employee password cannot make an unrecognized device a trusted TACACS client. Which remediation resolves the underlying fault while maintaining policy?

  1. The supported recovery is to repair device registration and secret alignment then test login and command authorization.
  2. The supported recovery is to disable shared-secret checks throughout device administration.
  3. The supported recovery is to use the logged-in employee password as the TACACS device shared secret.
  4. The supported recovery is to register only the switch hostname while its actual client source IP differs.

Explanation

Correct Answer

A:

TACACS+ requires a recognized client and shared secret consistent with both the device and server. Recheck tACACS source IP, ISE network device object, shared secret verification, TCP connection and live authentication result.

Incorrect Answers

B:

Disable shared-secret checks throughout device administration. This action does not repair the identified failure. A correct employee password cannot make an unrecognized device a trusted TACACS client. Instead, repair device registration and secret alignment then test login and command authorization. For the specific situation, an administrator migrates from an old TACACS server and forgets to match shared secrets on routers and ISE.

C:

Use the logged-in employee password as the TACACS device shared secret. This action does not repair the identified failure. A correct employee password cannot make an unrecognized device a trusted TACACS client. Instead, repair device registration and secret alignment then test login and command authorization. For the specific situation, an administrator migrates from an old TACACS server and forgets to match shared secrets on routers and ISE.

D:

Register only the switch hostname while its actual client source IP differs. This action does not repair the identified failure. A correct employee password cannot make an unrecognized device a trusted TACACS client. Instead, repair device registration and secret alignment then test login and command authorization. For the specific situation, an administrator migrates from an old TACACS server and forgets to match shared secrets on routers and ISE.

Question 1141

A router administrator from Active Directory is rejected because the device-admin policy uses an unrelated internal identity store. Which administrator action is appropriate for this ISE access-control problem?

  1. Build precise TACACS device-admin policy sets selecting the appropriate identity source and authorization conditions.
  2. Authenticate every network operator through an unrestricted shared local account.
  3. Assume a successful LDAP connection automatically selects the right TACACS policy.
  4. Use only a VLAN number to decide permitted CLI command privileges.

Explanation

Correct Answer

A:

Verify the effect through tACACS selected policy, authenticated identity source, AD group, requested service and authorization result. For the specific situation, a router administrator from Active Directory is rejected because the device-admin policy uses an unrelated internal identity store.

Incorrect Answers

B:

An overly broad policy can grant administrative commands outside the intended job role. This does not implement the required control for TACACS policy set identity source matching.

C:

Assume a successful LDAP connection automatically selects the right TACACS policy. This alternative overlooks a required prerequisite or targets the wrong function. TACACS device-admin policy selects both identity validation and role-based command privileges. The relevant evidence is tACACS selected policy, authenticated identity source, AD group, requested service and authorization result. For the specific situation, a router administrator from Active Directory is rejected because the device-admin policy uses an unrelated internal identity store.

D:

An overly broad policy can grant administrative commands outside the intended job role. For the specific situation, a router administrator from Active Directory is rejected because the device-admin policy uses an unrelated internal identity store.

Question 1142

A router administrator from Active Directory is rejected because the device-admin policy uses an unrelated internal identity store. Which collected records establish that the ISE decision actually took effect?

  1. TACACS selected policy, authenticated identity source, AD group, requested service and authorization result.
  2. A switch interface description without any live AAA request or response.
  3. An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
  4. A current login screenshot from a completely unrelated ISE deployment.

Explanation

Question 1144

A router administrator from Active Directory is rejected because the device-admin policy uses an unrelated internal identity store. An operator proposes the following incorrect shortcut: Authenticate every network operator through an unrestricted shared local account. What specific security or operational failure should be anticipated?

  1. An overly broad policy can grant administrative commands outside the intended job role.
  2. Reading the authentication event report caused the original network access outage.
  3. The only result is an unrelated portal background color change.
  4. Accurate device accounting automatically created every earlier failed EAP exchange.

Explanation

Correct Answer

A:

The shortcut is unsuitable because tACACS device-admin policy selects both identity validation and role-based command privileges. For the specific situation, a router administrator from Active Directory is rejected because the device-admin policy uses an unrelated internal identity store.

Incorrect Answers

B:

This unrelated assertion does not explain the TACACS policy set identity source matching problem. The relevant risk is that an overly broad policy can grant administrative commands outside the intended job role.

C:

This unrelated assertion does not explain the TACACS policy set identity source matching problem. For the specific situation, a router administrator from Active Directory is rejected because the device-admin policy uses an unrelated internal identity store.

D:
